Factory Direct Supply High Speed Combined Compound air Vent Pressure Release Valve Dn 20

Description

This product is used on the highest point of the pipeline or the place where there is airtight to remove the gas in the pipe to clear the pipeline and achieve normal work. If the exhaust valve is not installed, the liquid flowing in the pipe will generate dynamic heat and cause gas, forming a section. Make the water output of the pipeline meet the design requirements. Secondly, when the pipeline is running, there will be a power outage or a negative pressure in the pipeline, which will cause the pipeline to vibrate or rupture. The exhaust valve quickly sucks air into the pipe to prevent the pipeline from vibration or rupture. When the air is exhausted, water enters the valve to float the ball, and the transmission plug is closed to stop the exhaust. For example, when the pipeline is in normal operation, a small amount of gas will naturally be generated and collected in the upper part of the pipe. To a considerable extent, the water level in the valve drops, and the floating ball drops at any time and the gas is discharged from the small hole. If there is a power outage, the pump is stopped, and the water in the pipe is empty, negative pressure will appear in the pipe at any time, and the float will drop along the water. Open the small hole to drive the large hole to enter a large amount of air to ensure the safety of the pipeline.
