Exhaust valve is a kind of valve on fluid pipeline, but many customers are not very clear about its selection. Today, Gongao Valve will introduce relevant knowledge for everyone.
1: The position of the exhaust valve is more important than the diameter.
2: For long-distance pipelines, the ideal exhaust method is to install a large number of exhaust valves with a smaller diameter in a shorter distance (generally 500 to 1 000 m), rather than installing a larger diameter but quantity Exhaust valves with few and long intervals.
3: In most cases, it is required to install a three-function combination valve of small capacity automatic exhaust, large capacity system water filling exhaust and system emptying and vacuum destruction, that is, a compound exhaust valve.
4: When there are different slopes on the top two sides, determine the size of the exhaust valve according to the slope of the harsh conditions.
5: If you choose an exhaust valve without slow closing, it is best to install two exhaust valves, one large and one small, in one place. If you choose a slow-closing exhaust valve, just install one at the top of the pipe. For undulating pipelines, exhaust valves should be installed at all high points.
