一、V-DYC-JQ型系列电磁真空压差式充气阀概述

V-DYC-JQ型系列电磁真空压差式充气阀，是安装在机械真空泵上的专用阀门。安装于机械真空泵的进气口，并于泵同步开启和关闭。当泵停止工作或电源突然中断时，阀门能依靠大气与真空的压差力使阀板自动关闭，将真空系统封闭，保持其真空度，并将大气通过阀的节流孔充入泵腔内，从而避免泵油逆流污染真空系统。
适用的工作介质为空气及非腐蚀性气体。

The V-DYC-JQ series electromagnetic vacuum pressure differential inflation valve is a specialized valve installed on mechanical vacuum pumps. Installed at the inlet of the mechanical vacuum pump and synchronously opened and closed with the pump. When the pump stops working or the power is suddenly interrupted, the valve can rely on the pressure difference between the atmosphere and vacuum to automatically close the valve plate, seal the vacuum system, maintain its vacuum degree, and fill the pump chamber with atmosphere through the throttle hole of the valve, thereby avoiding pump oil backflow and pollution of the vacuum system.

The applicable working medium is air and non corrosive gases.
