Heating metering transformation temperature control valve is the key

heating metering transformation regulation is the premise, metering is the means, energy saving is the purpose, and the indoor radiator regulating valve is the only device that users can adjust independently. It must be transformed and installed, otherwise the purpose of energy saving will not be achieved. Therefore, no matter what scheme is selected, without good temperature control products, energy saving is equal to empty talk

the heating metering transformation also has some unique performance. Regulation is the premise, measurement is the means, and energy saving is the purpose. The indoor radiator regulating valve is the only device used to minimize the corrosion of the metal contact installed in the module, which must be modified and installed, otherwise the purpose of energy saving will not be achieved. Therefore, no matter what scheme is selected, without good temperature control products, energy saving is equal to empty talk

the core of heating metering is the indoor temperature control device (also known as radiator thermostatic valve or radiator thermostatic valve, referred to as thermostatic valve or thermostatic valve for short). The thermostatic valve can adjust the temperature and heat energy flow of the heating system. Without the regulating effect of thermostatic valve, better energy-saving effect cannot be achieved. Only by choosing good thermostatic valve products can we have the practical effect of saving money. Saving money here does not mean saving the purchase cost of a single product, but saving the heating cost. Please indicate the source of Reprint: global valve

at present, with the deepening of the heating metering transformation process, it is well known that new buildings must be forced to install radiator thermostatic control valves. So, what is a good thermostatic valve (thermostatic valve) product like? According to the relevant national regulations and industry standards, the thermostatic valve must have the following functions: first, it has the function of removing blockage with water and pressure or replacing the valve core. During the heating period, due to various factors, the thermostatic valve cannot work effectively and normally. Under the condition that the heating cannot be stopped, the maintenance personnel can clear the blockage of the thermostatic valve or replace the valve core to ensure the normal operation of the whole heating system. Second, the thermostatic valve installed in the vertical double pipe system must have the function of preset resistance, in order to more effectively and reasonably adjust the flow of heating and the pressure of heating pipeline, and adjust the regional balance. These two requirements are mandatory technical requirements in the technical specification for heat metering (JGJ) issued by the Ministry of housing and urban rural development. Third, the Kv value of the thermostatic valve can be preset. Fourth, another important indicator of thermostatic valve is the water leakage of heating valve. Where there is a valve, there is the possibility of water leakage according to the data of the National Bureau of statistics, Especially using "Guoliang copper high conductivity corrosion-resistant copper alloy functional new material was just mass-produced in August. Therefore, whether the valve has the function of preventing leakage is a very important reference index to judge the advantages and disadvantages of the thermostatic valve.

thermostatic valve is an automatically controlled valve. When nobody uses it, the thermostatic valve will work repeatedly and automatically every day. When the thermostatic valve leaks, no one can judge at all, so, Thermostatic valve seems small, but it is an important livelihood issue

for new residential buildings, it is recommended to select thermostatic valves that should have the following basic functions: (1) no special tools can be used to clean up or replace the valve core with water pressure, and special tools can be used to clean up or replace the valve core with water pressure. There is a big difference between the two. The use of special tools is very convenient, and the tools are small and available everywhere. You can repair and replace it by yourself, while special tools are special tools, which are expensive and not retail. (2) The vertical double pipe system must have the function of preset resistance coefficient to solve the problem of hydraulic imbalance. (3) Anti leakage function, so that users can rest assured

recently, the heating metering transformation of old residential buildings across the country is also gradually carried out, and many transformation schemes have emerged, basically focusing on household control. The so-called household control refers to the measurement and temperature control based on households. No matter what scheme is selected, temperature control products must be included. At present, the commonly used products include: electric heating valve, electric two-way valve, electric ball valve and other related products. These products use 220V strong current for water system. The core driving element of the electric heating valve is the paraffin bulb, which is composed of paraffin and metal powder. Under the condition of heat conduction, the paraffin and metal powder in the bulb are very easy to be layered, resulting in the deposition of metal powder, which accelerates the failure of the electric heating valve. At the same time, the electric heating valve cannot drain and replace the valve core

for the reconstruction of existing (old) residential buildings, it is recommended to select the basic functions of household control temperature control valve: (1) safety products with working voltage lower than 24 volts will not have leakage, electric shock and other conditions. (2) The working power should be less than 1 watt, which saves both thermal energy and electrical energy consumption. (3) After abnormal power failure, the valve should be in the normally open state to avoid the influence of the heating system and unnecessary disputes. (4) It can remove the blockage with water and pressure or replace the valve element, which is convenient for maintenance. (5) The anti leakage function makes users feel more at ease. (6) It is also a necessary condition to protect the normal operation of the heating system that the product can automatically return to its position (i.e. keep it normally open) after failure

it is very important to choose good temperature control products, which is related to the vital interests of the people. In particular, development enterprises, construction enterprises, heating enterprises and heating transformation enterprises must choose temperature control products that meet the national technical standards, truly do practical things for the people, and lay the foundation for promoting the benign development of heating metering in China
