品牌：RETZ瑞茨/我們一直致力于流體控制領域的持續創新，始于2005……進口真空直動式電磁閥廣泛應用真空泵等設備上，電磁閥與泵并聯在一起受泵的開關控制，當泵的開啟或者停止時，同步控制了不銹鋼直動式真空電磁閥的開啟與關閉。當泵停止工作或電源突然中斷時，真空電磁閥能自動將系統封閉，并將大氣通過泵的進氣口充入泵腔，避免泵油返流污染真空系統。真空電磁閥適用的工作介質為空氣及非腐蝕性氣體
The imported vacuum direct acting solenoid valve is widely used in equipment such as vacuum pumps. The solenoid valve is connected in parallel with the pump and is controlled by the pump's switch. When the pump is started or stopped, it synchronously controls the opening and closing of the stainless steel direct acting vacuum solenoid valve. When the pump stops working or the power supply is suddenly interrupted, the vacuum solenoid valve can automatically close the system and charge the atmosphere into the pump chamber through the pump's air inlet, avoiding the return flow of pump oil from polluting the vacuum system. The working medium suitable for vacuum solenoid valves is air and non corrosive gases
工作原理 working principle
進口真空直動式電磁閥常閉型 retz Imported large direct acting solenoid valve, normally closed type
斷電時呈關閉狀態，當線圈通電產生電磁力，使動鐵芯克服彈簧力和靜鐵芯吸合直接開啟閥口，介質通過；當線圈斷電時電磁力消失，動鐵芯在彈簧力的作用下復位，直接關閉閥口，介質不通。
When the normally closed type is powered off, it is in a closed state. When the coil is energized, electromagnetic force is generated, causing the moving iron core to overcome the spring force and the static iron core to directly open the valve port, and the medium passes through; When the coil loses power, the electromagnetic force disappears, and the moving iron core recovers under the action of spring force Position, directly close the valve port, medium blocked
