Eliminate Pipe's Air , Work Efficiency Composite Exhaust Valve
Flange Connection
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.
