DDC-JQ型電磁真空帶充氣閥
DDC-JQ型-電磁真空帶充氣閥概述
DDC-JQ型電磁真空帶充氣閥是機械真空泵安全閥，安裝于機械真空泵的進氣口，并與泵同步開啟和關閉。當泵停止工作或電源突然中斷時，閥門自動關閉，使真空系統保持真空并將大氣充入泵腔內，從而避免泵油逆向流動而污染真空系統。適用介質為純凈空氣或非腐蝕性氣體。
DDC-JQ electromagnetic vacuum belt inflatable valve is a mechanical vacuum pump safety valve, installed in the mechanical vacuum pump inlet, and synchronously open and close with the pump. When the pump stops working or the power supply suddenly interrupts, the valve automatically closes, so that the vacuum system keeps vacuum and fills the air into the pump cavity, thereby avoiding the reverse flow of pump oil and polluting the vacuum system. The applicable medium is pure air or non corrosive gas.
