Introduction of compound exhaust valve
Composite exhaust valve for high * * * on the pipeline or where breath, excluding the gas pipe to clear the pipe, to work properly, if you do not install the exhaust valve, pipe flow generated in the liquid heat caused by gas, the formation of short circuit, the water pipeline capacity is not up to the requirements, secondly, power outages stop the pump pipe negative pressure pipeline operation, which will cause vibration or pipeline rupture, row (suction) valve quickly from the air suction tube, to prevent vibration or pipeline rupture.
 
Structure features of compound exhaust valve
Sewage composite exhaust valve has a cylindrical body, a total internal main stainless steel ball and plug. The valve installed at the pump outlet or distribution Po water line, to exclude a large number of air in the pipe assembly, to improve water and pump efficiency, and once the tube is negative, this valve can quickly inhaled air, in order to keep the line due to the negative pressure generated damage.
 
Composite exhaust valve application:
1. medium: clear water
2. temperature: room temperature
3. body: gray cast iron HT200
4. float and plug: stainless steel
5., sealing material: butyl rubber
6. body test pressure: 1.5MPa
7. floating ball, sealing test, pressure:
