DYC-JQ型－电磁真空压差阀 |
|
|
■ |
DYC-JQ型电磁真空压差阀是机械真空泵安全阀，安装于机械真空泵的进气口，并与泵同步开启和关闭。当泵停止工作或电源突然中断时，阀门利用大气压力使阀板自动关闭，使真空系统保持真空并将大气充入泵腔内，从而避免泵油逆向流动而污染真空系统。适用介质为纯净空气和非腐蚀性气体。 |

DYC-JQ Electro-vacuum
DifferentialPressure Valve |

|
■ |
DYC-JQ electro-vacuum differential Pressure valveis
a safely valve for mechanical vacuum pump. It is mounted at
theintake nozzle of mechanical vacuum pump, synchronously opened
andclosed with the pump. In case that pump stops working or
powersupply is suddenly broken off, valve disc will be
closedautomatically under atmospheric pressure, to keep the vacuum
systemvacuum and the air charged into pump cavity, thus to prevent
pumpoil from reverse flow that can pollute the vacuum
system.Applicable medium can be pure air or noncorrosive
gases. |
