Introduction:
The valve is arranged in the input pipeline, which is used to eliminate the air in the pipe and improve the work efficiency. When the pipeline produces negative pressure, the valve can quickly absorb the outside air and prevent the pipeline from being damaged. Begin water injection pipeline, the valve in the open position, to a large number of exhaust, when the air is exhausted, a floating ball rises, close the valve, to stop the exhaust, such as a small amount of air valve in the water decreased, air is discharged through the small hole; when the pump stops, pipeline to generate negative pressure, valve flap to open quickly, inhaled air to ensure pipeline safety.
This vavle is suitable on system such as petroleum, chemical industry, foodstuff, medicine, papemaking, water and electricity, shipping, plumbing, the smelting and sources of energy etc the pipe route. Can regard on gas, liquid, semifluid as well as solid powder pipes and power lines and the container of many kinds of corrosiveness and non-corrosiveness adjusts and dams a river the equipment use. Especially extensively being in high layer of building fire protection system reaches other to show in the pipes and power lines system of valve of vavle switch state.
