What is the function of air relief valve?
The main function of the air relief valve is to regulate the pressure of gas (such as air, oxygen, hydrogen, liquefied gas, natural gas, etc.), ensure the stable flow of gas in the pipeline, and protect the system from damage caused by excessive pressure. The following are the specific functions of the air relief valve:
Pressure regulation: The air relief valve adjusts the outlet pressure of the gas through the internal main valve and pilot valve assembly to keep it within the set range. This helps to maintain the stable operation of the gas system and prevent pressure fluctuations.
Pressure stabilization function: In the case of constantly changing inlet pressure, the air relief valve can keep the outlet pressure and temperature values within a certain range to ensure the quality and safety of the gas.
Safety protection: The relief valve also has safety protection functions, such as automatically opening the safety valve when the outlet pressure rises abnormally, releasing excess pressure, and preventing the system from being damaged due to excessive pressure.
Installation and maintenance: The air relief valve is usually installed on a horizontal pipeline for easy maintenance and operation. In addition, during installation, it should be noted that the flow direction of the medium is consistent with the direction of the arrow shown on the valve body to ensure the normal operation of the pressure reducing valve.
In short, the air relief valve is an indispensable part of the gas system. It ensures the safe, efficient and stable flow of gas through precise pressure regulation and pressure stabilization functions.
