Vacuum valve and it's purpose

Vacuum valve:

Vacuum valve refers to a vacuum system component used to change the direction of airflow, adjust the flow rate, and cut off or connect pipelines in a vacuum system.

Purpose of universal vacuum valves:

The electromagnetic vacuum belt inflation valve and electromagnetic vacuum differential pressure valve are vacuum valves specifically designed to prevent oil return from mechanical vacuum pumps. They are installed at the air inlet of the mechanical vacuum pump and open and close synchronously with the pump. Generally, it cannot be used elsewhere, which means it cannot be used for venting in vacuum systems. The advantage of using an electromagnetic vacuum differential pressure valve is that it consumes very little electricity and saves energy; The valve body material for DN ≤ 50 is aluminum alloy, with light weight, small volume, and fast valve plate closing speed.

Baffle valves are used in corner and tee connections in vacuum pipelines. The driving mode is determined by the user, including manual, pneumatic, electromagnetic, and electric. The GDC-J electromagnetic high vacuum baffle valve is sealed with metal corrugated pipes, which has a wide range of applications and can also be used as an inflation valve; The installation position can be arbitrary, and it can withstand an atmospheric pressure, with feedback signal output.

Plug valves are used in situations with high vacuum requirements or pipeline size requirements. Full conductivity, valve leakage rate of 10-7Pa.L/S, bi-directional sealing. The driving mode is determined by the user, including manual, pneumatic, and electric. Both pneumatic and electric devices are equipped with signal feedback devices.

Diaphragm valves and ball valves are straight through and can be used in situations where positive pressure and vacuum coexist. The driving mode is determined by the user, including manual, pneumatic, and electric.

The butterfly valve is in a straight through form, 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 intelligent pneumatic and electric butterfly valves can also be adjusted at will.
