Answer

Are you looking for the price of a mixer? Are you looking for a water mixing device to replace the bath mixing valve? Do you think the price of water mixer is expensive? Let the editor show you the Chengde Longzhida water mixer.

 

First of all, the Chengde Longzhida water mixer needs an external power supply to be used. It cannot be heated and can only mix hot and cold water. Secondly, the water mixer is composed of an induction control part and a mixing execution part. The sensing part uses a temperature sensor to sense the change in water temperature, uses a microcomputer to control and adjusts the ratio of cold and hot water, and implements some mixing. The execution part has a mystery inside the mixing bucket, not just one or several mixing blades. Instead, the water is cut into several sections, without the vortex mixing blades. Ensure that the water temperature in each part of the barrel is consistent, and the temperature set in advance can be quickly mixed. Generally, the temperature control accuracy can reach 0.5°C.

 

Well, after a simple understanding of the structure and working principle of the mixer, I think it is time to talk about the price of the mixer that you are most concerned about. We also learned that the internal structure of the mixer is designed to include temperature sensors, solenoid valves (more than one), and electronic components. The biggest difference between it and the water mixing valve is the infusion of higher technology. So now I compare the price of the traditional mixing valve with the mixer, you may be more "knowledge".

 

1. The price of a single-piece valve of the mixing valve ranges from tens to hundreds of prices in the market, and there is often more than one mixing valve for bath mixing. If a standard of 100 yuan is used by the public, 20 showers will cost 2,000 yuan. The thermostatic mixing valve is more expensive. In Alibaba, one usually costs two hundred or three hundred, and a package of 500 yuan after sale. So 20 showers cost 10,000 yuan.

 

2. There are two common water mixing valves. The installation structure of these two water mixing valves is not the same: one is that can be turned to the right and the handle can be turned upwards for water supply. The middle port is the water outlet, and the ports at both ends are connected to cold and hot water; the other type of mixing valve has a switch on the left dedicated to water supply. This type of mixing valve usually connects the upper port to hot water, and the lower port to For cold water, the right port is for water. The first thing to make sure for you is: Ordinary mixing valve can not be installed according to the cold and hot signs; but the thermostatic mixing valve with constant temperature water must be installed according to the cold and hot signs, and it must not be installed, otherwise there will be no water or water coming out. It may be all cold water or all hot water. The mixing valve is a valve that mixes hot and cold water. In fact, the valve itself cannot be mixed, but it is connected to the cold and hot water pipes to play a mixing role. There are two types of water mixing valve installation: one is the shower and bathtub faucets directly installed on the wall, the distance between hot and cold water is generally about 14.5cm, equipped with specific connection accessories, and higher requirements for the interface; The kind is connected by a hose, and its connection requires the installation of a triangular valve at the hot and cold water outlets and a metal hose to connect the valve. As for the need for S-bends, this concept is confusing and unclear. The cost of this accessory and the cost of installation labor are carefully calculated, and it may not be cost-effective to have a mixer.

 

4. The water temperature mixed by the water mixing valve is unstable, and people will waste a lot of water when adjusting the water temperature. The water mixer has no problem of wasting, and the leftover cold water can be recycled and mixed for use the next day. The cost of bath water can be saved in the long run.

 

5. The water mixer does not need to add any accessories at all. There is at most one water tank, and this water tank is also a necessary container for most baths. We sell a set of mixers as a complete machine plus installation plan. We will also send people to provide installation services, and the after-sales service is also first-class. lifetime warranty. No need for those messy accessories. Central mixing water, unified water delivery.

 

6. In addition, the water mixer has an over-temperature and under-temperature alarm function. Ensure safety and help you avoid the risk of scalding customers.

 

Do you think the price of water mixer is expensive? If you are interested in contacting Manager Qiu by phone: 15343144268

What brand is good for Heilongjiang bath mixing equipment? Heilongjiang has always been a large province that uses coal. In addition to heating in winter, the amount of coal used to boil water in baths is also numerous. At present, the state has repeatedly mentioned water charges, and the heating of baths has also introduced some policies to restrict coal burning. Energy saving and water saving are no longer empty slogans. We solemnly promise that the use of constant temperature mixing equipment baths can save 40% of water resources and also save heat.

 

What brand is good for Heilongjiang bath mixing equipment? The temperature in Heilongjiang is relatively cold, so the bath water temperature is not easy to keep warm. The heat preservation of the water tank is no longer enough to meet the needs of constant temperature. The real constant temperature still needs to use water mixing equipment to monitor the mixing in real time. Chengde Longzhida Water Mixing Equipment uses temperature sensors, solenoid valves, and fully automatic microcomputer control to help you manage the bath water temperature like a robot. The shower water is supplied stably with constant temperature and pressure, and the temperature control accuracy reaches 0.5℃, saving a lot of water resources, heat energy, coal and gas.

 

What brand is good for Heilongjiang bath mixing equipment? The mixing barrel of Chengde Longzhida Water Mixing Equipment adopts a vortex mixing structure, which ensures that the cold and hot water are fully mixed in a short and small container, reduces the product volume, and saves a lot of space and materials. The product is designed with five abnormal state alarm indications: no cold water, no hot water, cold water temperature too low, hot water temperature too high, and system abnormality, ensuring the safety and maintainability of the product. Chengde Longzhida water mixing equipment has simple structure, small size, constant output water temperature and fast adjustment speed. It has changed the traditional manual or mechanical type-the water tank needs to be mixed in advance, and long-term storage causes waste of energy and water resources. When it comes to both use and mixing, use more and more, use less and less to achieve the effect of energy saving and water saving, which not only ensures the use of users, but also avoids waste.

Answer

How to use water mixer——The HSZ series bath thermostat water mixer produced by Chengde Longzhida Company adopts microcomputer control technology, uses advanced temperature sensor detection feedback method, and controls solenoid valve to automatically adjust the output water temperature. . The whole set of equipment is composed of two parts, one is the intelligent control electric control part, and the other is the execution part of the water mixing machine.

 

How to use the water mixer-first of all, you need to understand that the water mixer is just a water mixing device, which only has the function of mixing water and maintaining a constant temperature, not a heating device. This bath is mainly to understand.

 

Secondly, the water mixer needs to be plugged in when in use, and the hot water needs to be heated by another boiler or other heating equipment to provide hot water, and the water temperature is below 75 degrees Celsius. Or you can buy hot water, set the mixed water outlet temperature according to the digital display part, and wait for the water temperature to mix. This process is very fast, about 2 minutes.

 

Next, you don’t need to control anything, just leave it to the water mixer. The water temperature difference will not exceed 0.5 degrees Celsius throughout the day, and there is no need to hire someone to manage the water temperature. How does the water mixer achieve such precise temperature control accuracy? It is not a simple heat preservation, but a microcomputer detects the water temperature, the water temperature is under-temperature, over-temperature, and it will replenish and mix at any time. Let's take a look at the working principle of the water mixer.

 

How to use water mixer:

 

(1) The electrical controller of the mixer is composed of a DC stabilized power supply, a single-chip computer, a temperature sensor, and control software. It is used to control the solenoid valve of the water mixing mechanical actuator. According to different flow, water temperature, the system automatically controls the actuator to output constant water.

 

(2) The execution part of Chengde Longzhida water mixing equipment is composed of solenoid valve group, mixing bucket, mixing blade and other actuators. Under the control of the controller, it realizes the full mixing of cold water and hot water. The pressure difference of the hot water is used to mix the cold water into the hot water, and under the action of the mixing blade, the cold and hot water can be fully mixed to output constant temperature hot water.

 

(3) The electrical controller of the desktop water mixer above HSZ-50BP is equipped with a variable frequency controller to control the output pressure of the cold water pump to achieve constant pressure water supply. At the same time, the electrical controller is equipped with a pipeline return pump circulation system controller, which can automatically circulate the cold water in the pipeline back to the water tank, avoiding the waste of water resources caused by the discharge of cold water in the pipeline.

 

The water mixer is easy to use and has stable performance. It is especially suitable for large baths and bathing places. It can also be applied to food processing that requires constant temperature water, or factory equipment cleaning and supplying constant temperature hot water, etc.

Answer

The water meter rotation may have one or several of the following reasons

 

1. The user's indoor pipeline or water appliance leaks. It is easy to find leaks in the taps of general users. However, due to the large-scale application of concealed projects in modern buildings, the water supply pipelines of many buildings are buried underground or in walls. It is difficult to detect the leakage of the pipelines laid by this method. At this time, the user is actually Water is used, but the water flows slowly in the pipe.

 

2. Water users illegally use water. In daily life water, individual users, especially users in areas with low water pressure, in order to use water appliances (mostly shower appliances) in their homes, install pumps directly on the tap water pipes in their homes. When the water pump or valve is started or stopped, water hammer often occurs, impacting the water meter impeller to make the water meter rotate.

 

3. The pipeline water pressure fluctuates. As a kind of liquid, water has compressibility when the pressure of water supply pipeline is high. Pressure fluctuations in the water pipeline are inevitable. When the pressure in the main network increases, the volume of water in the pipeline after the meter decreases due to the increase in pressure. At this time, a small amount of water passes through the water meter to produce a positive rotation. turn. Since the resistance of the internal gear of the water meter is greater than the resistance during the forward rotation, even if the water intake at both ends of the water meter is the same, the readings reflected on the water meter will be different, and the overall performance is forward rotation.

 

4. Dissolved gas in water overflows. A large amount of gas will be dissolved in the production process of tap water, and gas will accumulate in the pipeline during pipeline construction. If the home does not use water for a long time or the pipeline design is unreasonable, the highest point or protruding point of the pipeline will generate air bags. Due to the strong compressibility of gas, if there are pressure fluctuations in the pipeline at this time, the space in the pipeline behind the meter will expand and contract, so the water meter will produce a greater amount of rotation. At present, most users' water meters rotate due to the existence of air bags in the pipes behind the meters.

 

5. Improper design and construction of water supply pipeline facilities. When installing the water meter, the necessary straight pipe sections or equivalent water flow rectifiers should be installed upstream and downstream of the water meter (upstream straight pipe length ≥ 10D, downstream straight pipe length ≥ 5D, and the water rotation caused by the bent pipe and the water pump must be Install the rectifier device before the straight pipe section) so as not to affect the accuracy of water meter measurement. However, in actual construction, due to limited space in the pipeline gallery, or poor management, the workers did not operate as required, and the water meter installation was not standardized.

 

Take appropriate control methods according to different reasons:

 

1. Replace all the pipes in the home that have been in disrepair for a long time, and check the water appliances such as toilets and concealed pipes one by one to reduce unnecessary water expenses.

 

2. Once someone is found to use water in violation of regulations, they should immediately report to the water supply company to eliminate the phenomenon of illegal water usage.

 

3. Water compression due to pipeline pressure fluctuation is one of the reasons for the rotation of the water meter. Consider installing a check valve to prevent the water from flowing back. To facilitate installation, a water meter with a built-in check valve can be selected. Due to the high frequency of residential water use and the small fluctuations in pipeline pressure, the quality and sensitivity of the check valve should be paid attention to when selecting check valves or water meters.

 

4. In order to effectively remove the gas in the pipeline and avoid the occurrence of airbags, attention should be paid to: rationally arrange the exhaust valve when designing the pipeline; reduce pipe bends and bending points when installing the pipeline at home, and design the highest point of the pipeline at the frequently used faucet; The valve should be opened slowly when the new pipeline passes water for the first time, and the gas in the pipeline should be emptied as much as possible; the dead water pipe section that appears during the household meter reformation is easy to produce airbags, so try to remove or modify it; when the water meter is designed and installed, ensure that the straight pipe section meets the installation requirements of measuring instruments.

 

Water meter rotation is a problem caused by comprehensive factors. Users are requested to check the reasons for inaccurate water meter readings. Existing methods can significantly reduce the phenomenon of rotation. At the same time, users are reminded to purchase high-quality, guaranteed after-sales water meter manufacturers' products.
