Vacuum Valve Use
Electromagnetic vacuum belt inflation valve and electromagnetic vacuum differential pressure valve are vacuum valves specially used to prevent mechanical vacuum pumps from returning oil. They are installed at the inlet of mechanical vacuum pumps and open and close in synchronization with the pumps. Generally cannot be used elsewhere, that is to say cannot be used for deflation in vacuum systems. The advantage of using electromagnetic vacuum differential pressure valve is that it consumes little power and saves energy; the valve body material of DN≤50 is aluminum alloy, light weight, small size, and fast closing of the valve plate.
Baffle valves are used in corner and tee positions in vacuum pipes. The driving modes are manual, pneumatic, electromagnetic and electric. Among them, the GDC-J electromagnetic high vacuum baffle valve is a metal bellows seal, which has a wide range of applications and can also be used as an inflation valve; the installation position can be arbitrary, can be reversed to an atmospheric pressure, and has a feedback signal output.
The flapper valve is used in places with high vacuum requirements or high pipe sizes. All-way conduction, valve leakage rate is 10-7Pa.L / S, two-way sealed. The driving mode is manual, pneumatic and electric. Both pneumatic and electric with signal feedback device.
Diaphragm and ball valves are straight-through, and can be used in situations where both positive pressure and vacuum coexist. The driving mode is manual, pneumatic and electric.
The butterfly valve is a straight-through type, and the three driving modes of manual, pneumatic and electric are determined by the user. The opening angle of the manual butterfly valve can be adjusted arbitrarily; the opening angle of the intelligent pneumatic and electric butterfly valves can also be adjusted arbitrarily.
Conditions of use of the valve:
- The medium is pure air or non-corrosive gas.
- The medium temperature is determined by the extreme temperature of the rubber used.
