What is the function of installing a pressure relief valve?

[LaAnnie]

The function of installing a pressure relief valve is: when the upper limit of the system's safe working pressure is reached, it can automatically open or close, reducing the working pressure and ensuring system safety. The pressure relief valve, also known as a safety valve, is a device that can automatically open or close based on the system's working pressure. It is generally installed on equipment or pipelines of closed systems to protect system safety. The pressure relief valve consists of components such as a needle valve, pressure gauge, main valve, pilot valve, and connecting pipes. The main valve is divided into upper and lower parts by a diaphragm. The lower chamber of the diaphragm serves as the water flow channel, while the upper chamber is the control room, which controls the opening and closing of the main valve disc.
