Purpose of vacuum valve:
The electromagnetic vacuum charging valve and the electromagnetic vacuum differential pressure valve are vacuum valves specially used to prevent oil return from the mechanical vacuum pump. They are installed at the air inlet of the mechanical vacuum pump and are opened and closed synchronously with the pump. Generally, it cannot be used in other places, that is to say, it cannot be used for venting in the vacuum system. The advantage of using Niwei electromagnetic vacuum differential pressure valve is that the power consumption is very small and energy is saved; The valve body with DN ≤ 50 is made of aluminum alloy, which is light in weight, small in size and fast in closing.
The flapper valve is used in the corner and tee of the vacuum pipeline. The driving modes are manual, pneumatic, electromagnetic and electric, which are determined by the user. Among them, GDC-J electromagnetic high vacuum flapper valve is a metal bellows seal, which has a wide range of applications and can also be used as an air charging valve; The installation position can be arbitrary, and the pressure can be reversed to one atmosphere, with feedback signal output.
The gate valve is used in the situation where the vacuum degree is high or the pipe size is high. Full conduction, valve leakage rate is 10-7Pa L/S, double sealing. The driving mode is determined by the user. Both pneumatic and electric devices are equipped with signal feedback devices.
Diaphragm valve and ball valve are straight through type and can be used in situations where positive pressure and vacuum coexist. The driving mode is determined by the user.
The butterfly valve is a straight through type, and the manual, pneumatic and electric drive modes are determined by the user. The opening angle of manual butterfly valve can be adjusted at will; The opening angle of intelligent pneumatic and electric butterfly valves can be adjusted at will.

Service conditions of valves:
1. The medium is pure air or non corrosive gas.
2. The medium temperature is determined by the extreme temperature of rubber.

Vacuum valve refers to the vacuum system element used in the vacuum system to change the air flow direction, adjust the air flow, and cut off or connect the pipeline. The closing element of vacuum valve is sealed with rubber sealing ring or metal sealing ring.
The bellows of the bellows stop valve is made of stainless steel, high zinc brass JI80, plastic and other materials. Diaphragm seals can be used for shut-off parts of stop valves with small diameters (diameters below 10 mm). Ball cock valves can be used for low and medium vacuum.
