公司名称：裕原流体控制（上海）有限公司

品牌：RETZ瑞茨/我们一直致力于流体控制领域的持续创新，始于2005……进口真空直动式电磁阀广泛应用真空泵等设备上，电磁阀与泵并联在一起受泵的开关控制，当泵的开启或者停止时，同步控制了不锈钢直动式真空电磁阀的开启与关闭。当泵停止工作或电源突然中断时，真空电磁阀能自动将系统封闭，并将大气通过泵的进气口充入泵腔，避免泵油返流污染真空系统。真空电磁阀适用的工作介质为空气及非腐蚀性气体
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
进口真空直动式电磁阀常闭型 retz Imported large direct acting solenoid valve, normally closed type
断电时呈关闭状态，当线圈通电产生电磁力，使动铁芯克服弹簧力和静铁芯吸合直接开启阀口，介质通过；当线圈断电时电磁力消失，动铁芯在弹簧力的作用下复位，直接关闭阀口，介质不通。
