High pressure automatic exhaust valve
The pipe network of the high-pressure water mist fire extinguishing system is very long, and the pipe network needs to be exhausted during the water filling process, and when the system is sprayed, due to the presence of a large amount of air in the pipe network, the pressure can not reach the normal working pressure in a short time, so the high-pressure automatic exhaust valve needs to be set at the highest point and end of the system pipe network. The function of high-pressure automatic exhaust valve is to achieve rapid exhaust when the empty pipe of the pipeline is filled with water, and when negative pressure is generated in the pipeline, it can quickly enter the air, and the device that can discharge the trace amount of air gathered in the pipeline under working pressure, and has an automatic sealing function after exhausting the gas, which does not affect the normal operation of the system.
The working pressure of high-pressure water mist is very high, are above 10MPa, our self-designed high-pressure automatic exhaust valve, working pressure greater than 16MPa or more, to meet the pressure test and working needs of the system pipeline.
Rated working pressure: 16MPa
Sealing test pressure: 24MPa
Material: 304/316 stainless steel
Connection thread: M18*1.5, G3/8, G1/4 (special thread can be customized)
