Characteristics and principle of pressure reducing valve
Release time:
2021-03-13
Temperature and Pressure Reducing ValveThis valve adjusts the flow rate of the medium by adjusting the opening degree of the opening and closing part in the valve body, reduces the pressure of the medium, and simultaneously adjusts the opening degree of the opening and closing part. The pressure after the valve is adjusted by the parts, keeping the pressure after the valve within a certain range, and cooling water is sprayed into or after the valve body to reduce the temperature of the medium. This type of valve is called a temperature and pressure reducing valve.
Temperature and Pressure Reducing ValveIts characteristic is that when the inlet pressure changes continuously, the outlet pressure and temperature are maintained within a certain range. The temperature and pressure reducing valve is an important accessory of the pneumatic control valve. Its main function is to reduce the air source pressure and stabilize it at a fixed value, so that the control valve can obtain stable air source power for adjustment and control. This valve should generally be installed horizontally in the pipeline.
According to the structure, it can be divided into diaphragm type, spring diaphragm type, piston type, lever type and bellows type. According to the number of valve seats, it can be manually single-seat and double-seat; according to the position of the valve disc, it can be divided into positive action and reverse action.
In modern industry,Temperature and Pressure Reducing ValveMainly used in the following fields:
1.Temperature and Pressure Reducing ValveIt is mainly used to reduce the temperature of superheated steam from the bypass system of a steam turbine to an effective temperature level, thus providing power for other equipment in factories that require saturated steam.
2. As part of a temperature and pressure reducing device, it reduces the temperature and pressure of superheated steam from a boiler or thermal power plant to the operating conditions required by the equipment. These processes include: food, textile, tobacco, brewing, papermaking, chemical, pharmaceutical, petrochemical, etc.
Temperature and Pressure Reducing ValveIt is widely used in various industries, and many companies produce this product, but the Price is indeed very confusing, because some have a high unit Price, while some companies offer very cheap Prices. This makes it difficult for customers to choose. If you choose a higher Price, you worry that it is not worth the Price, and if you choose a low-end one, you will worry about the quality. Here, I believe that many customers understand the concept of "you get what you pay for", so when choosing high-qualityTemperature and Pressure Reducing Valveproducts, we should also choose temperature and pressure reducing valves with moderate Prices.
