DYC-JQ series angle-pass electromagnetic vacuum differential pressure type with inflation valve
DYC-JQ series angle-pass electromagnetic vacuum differential pressure with inflation valve is a new type of vacuum valve installed on the air inlet of a mechanical vacuum pump. Its working principle is that the mechanical pump and valve are connected to the same circuit. When the vacuum pump needs to work When the operation is stopped or the power is suddenly cut off, the valve uses the pressure difference between atmosphere and vacuum to push the piston to automatically close the valve, cut off the connection between the pump and the vacuum system, maintain the vacuum degree of the vacuum system, and amplify the air to the vacuum pump to prevent the vacuum pump oil from returning to vacuum The system is conducive to restarting the vacuum pump. When the vacuum pump starts again, the valve uses the spring to push the piston open to open the valve.
The applicable working medium is air and non-corrosive gas.

DYC-Q series straight-through electromagnetic vacuum differential pressure with inflation valve
DYC-Q series straight-through electromagnetic vacuum differential pressure belt inflation valve is a new type of vacuum valve installed on the air inlet of a mechanical vacuum pump. Its working principle is that the mechanical pump and valve are connected to the same circuit. When the vacuum pump needs to stop running due to work , Or a sudden power failure, the valve uses the pressure difference between atmosphere and vacuum to automatically close the valve, cut off the connection pump of the pump and the vacuum system, maintain the vacuum degree of the vacuum system, and amplify the air to the vacuum pump to prevent the vacuum pump oil from returning to the vacuum system, which is beneficial The vacuum pump restarts. When the vacuum pump restarts, the valve uses gravity to automatically drop the valve plate to open the valve.
The applicable working medium is air and non-corrosive gas.
