Compound Exhaust Valve
Product overview
The composite exhaust valve body is in the shape of a barrel, which is used in the place where the highest point on the pipeline has a closed air to eliminate the gas in the pipe to dredge the pipe to achieve normal operation. Heat causes gas to form a short circuit, which makes the water output capacity of the pipeline fail to meet the design requirements. Secondly, when the pipeline is in operation, there will be a power outage, and a negative pressure in the pip-eline will cause the pipeline to vibrate or rupture. The exhaust valve quickly draws air into the pipe to prevent the pipeline from vibrating or rupturing.
Product Features
Compound exhaust valve is reliable, which can discharge a large amount of air in the pipeline and a small amount of gas in the system operation to the outside air at high speed. The compound exhaust valve can be easily removed from the system for maintenance, and the water in the system will not flow out, so there is no need to empty the system. Only exhaust, no drainage, steam, moisture off the disk design using a special structure, to ensure that no drainage. As long as the system has pressure, the compound exhaust valve will exhaust continuously.
