Product Description

DYC-JQ series electromagnetic vacuum differential pressure charging valve is a special valve installed on the mechanical vacuum pump. It is installed in the inlet of the mechanical vacuum pump, and synchronously open and close in the pump. When the pump stops working or the power supply is suddenly interrupted, the valve can rely on the pressure difference between the atmosphere and the vacuum to automatically close the valve plate, close the vacuum system, maintain its vacuum degree, and fill the atmosphere into the pump chamber through the throttle hole of the valve, so as to avoid the pump oil countercurrent pollution of the vacuum system. The applicable working medium is air and non-corrosive gas.

First, DYC-JQ electromagnetic vacuum with inflation differential pressure valve overview:
DYC-JQ type electromagnetic vacuum with inflation differential pressure valve is a necessary vacuum component in the vacuum system, it is installed in the mechanical vacuum pump air inlet on the special valve, and connected with the pump on the same power supply, pump open and stop directly control the opening and closing of the valve. When the pump stops working or the power supply is suddenly interrupted, the valve uses atmospheric pressure to make the valve plate automatically fall to close the vacuum system, and the atmosphere is inflated into the pump chamber through the valve's inflation port, so as to avoid the pump oil countercurrent and pollution of the vacuum system.
