The purpose of the universal vacuum valve electromagnetic vacuum belt inflation valve and electromagnetic vacuum differential pressure valve is a vacuum valve specially designed to prevent the mechanical vacuum pump from returning oil, installed in the air inlet of the mechanical vacuum pump, and opened and closed synchronously with the pump. Generally can not be used elsewhere, that is to say can not be used for deflation in vacuum systems. The advantage of using Niwei electromagnetic vacuum differential pressure valve is that the power consumption is small and energy is saved; the valve body of DN≤50 is made of aluminum alloy, which is light in weight, small in volume and fast in valve plate closing speed.
The flapper valve is used in corners and tees in the vacuum line. The driving method is hand, gas, electromagnetic, and electric, which are determined by the user. Among them, GDC-J electromagnetic high-pressure flapper valve is metal bellows seal, which has wide application range and can also be used as inflation valve; the installation position can be arbitrary, it can reverse the top one atmosphere, and has feedback signal output.
The flapper valve is used in applications where high vacuum requirements or high pipe sizes are required. Full-conductance, valve leakage rate of 10-7Pa.L / S, two-way sealing. The driving method of hand, gas and electric is determined by the user. Both pneumatic and electric have signal feedback devices.
The diaphragm valve and the ball valve are straight-through and can be used in situations where positive pressure and vacuum coexist. The driving method of hand, gas and electric is determined by the user.
The butterfly valve is in the form of straight-through, and the three driving modes of hand, gas and electricity are determined by the user. The opening angle of the manual butterfly valve is arbitrarily adjustable; the opening angle of the intelligent pneumatic and electric butterfly valves is also arbitrarily adjustable.
Valve use conditions:
1. The medium is pure air or non-corrosive gas.
2. The medium temperature is determined by the extreme temperature at which the rubber is used.
