What is the function of an automotive pipeline pressure relief valve?

[ChloeLee]

The function of an automotive pipeline pressure relief valve is to automatically open or close when the system reaches the upper limit of its safe working pressure, thereby reducing the working pressure and ensuring system safety. The pressure relief valve is essentially a protective device that safeguards the car engine and turbocharger. Also known as a safety valve, it is designed to automatically open or close based on the system's working pressure and is typically installed on equipment or pipelines in closed systems to protect system safety. The pressure relief valve consists of components such as a needle valve (I), a pressure gauge (2), a main valve (3), a pilot valve (4), and connecting pipes. The main valve is divided into upper and lower parts by a diaphragm, with the lower chamber serving as the water flow channel and the upper chamber as the control room, which regulates the opening and closing of the main valve disc.
