Carx composite exhaust valve

Short Description:

The compound exhaust valve body is barrel shaped, which is used for the place with closed air at the highest point of the pipeline to remove the gas in the pipe to dredge the pipeline, so as to achieve normal operation. If the exhaust valve is not installed, the liquid flowing in the pipe will generate dynamic heat, cause gas, and form a short circuit, so that the water discharge capacity in the pipe can not meet the design requirements. Secondly, in the operation of power failure, pump stop, the pipeline will appear negative pressure, which will cause pipe vibration or rupture, the exhaust valve will quickly draw air into the pipeline to prevent pipe vibration or rupture.
