进口防爆电磁阀 防爆电磁阀线圈 RETZ瑞茨品牌

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……进口防爆电磁阀线圈必须采用相等等级的防爆接线盒做过渡,线圈引出导线长度必须大于1m,防爆线圈与电磁阀配套使用时，介质温度不得超过60℃，阀体外露表面 温度不大于130℃,本产品广泛应用在制冷剂、油路管道、燃气管网、工业窑炉、城市 、 、天然气、化学等 危险场所使TheRETZ explosion-proof solenoid valve coil must use an explosion-proof junctionbox of equal grade as a transition, and the length of the coil lead wire mustbe greater than 1m. When the explosion-proof coil is used in conjunction withthe solenoid valve, the medium temperature should not exceed 60 ℃, and themaximum temperature on the exposed surface of the valve body should not exceed130 ℃. This product is widely used in explosive hazardous areas such asrefrigerants, oil pipelines, gas pipelines, industrial kilns, urban gas,liquefied petroleum gas, natural gas, and chemistry

进口防爆电磁阀工作原理--Workingprinciple of imported explosion-proof solenoid valve

常闭：当线圈通电时，先导阀芯吸合，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。

Normallyclosed: When the coil is energized, the pilot valve core is closed, the pilothole opens, the upper chamber of the valve is depressurized, the piston ispushed by the medium pressure in the lower chamber, and the solenoid valveopens. When the coil is powered off, the pilot valve core is reset by the spring,the pilot hole is closed, and the valve upper chamber is pressurized by thepiston orifice and the thrust of the reset spring, and the solenoid valve isclosed.
