Axotomized, turn the paper of the cam disconnect switch on the side of the circuit, forcing 3XK press paper cutter and a loss of power, but the operators have not yet had enough time to release the button, turn the paper cutting of the cam over the limit switch 3XK, 4J and 1 c was electric pick-up, gnashing paper cutter does not reset, in this case, a rotating cam on the other side lost your limit switch XM, intermediate relay 5J load-disconnected.

纸张切断后，转动的凸轮一侧断开行程开关3XK的回路，迫使压纸和切纸断电，但是操作者还未来得及松开切纸按钮，转动的凸轮滑过行程开关3XK后，4J和1C仍得电吸合，造成切纸刀不复位，这时，转动的凸轮另一侧断开了行程开关XK，中间继电器5J失电断开。

I keep some candle in the house in case that electric power should fail.

Coil power, the electromagnetic suction is zero, the Deputy valve valve plug and the dynamic role of the iron core because of spring brought up, the Deputy valve is opened, the main valve on the valve cup of fluid flow out through the SAFETY VALVES Vice-valve, reducing the role of the cup on the valve in the main valve pressure, when the main valve to reduce pressure on the valve cup to a certain value, the use of pressure to push the main valve valve cup, the solenoid valve is opened, media circulation.

线圈断电时，电磁吸力为零，副阀阀塞和动铁芯由于弹簧作用向上提起，副阀打开，主阀阀杯上的流体经副阀流走，减少了作用在主阀阀杯上的压力，当主阀阀杯上的压力减少到一定值时，利用压差把主阀阀杯推起，电磁阀打开，介质流通。& 2 two-pass solenoid valve works &是由中国针型阀网提供的国际阀门新闻，译文仅供参考。另外，中国针型阀网还提供相关产品搜索：针型阀型号、针型阀价格、针型阀技术、针型阀新闻、针型阀生产商等。

Normal Open Type A unique application of the direct-acting valve structure, when power to the electromagnetic coil when the head is located in the coil around the core component may generate a static magnetic, gravity and Balance valves magnetic components to overcome the stem return spring will be moving core, together with the elastic Stem components suck up with effect, so that even in the solid components of the valve stem disc closely aligns closely with the valve seat and seal, the valve closed; power, the valve plate in the return spring and the stem components of gravity under restoration in situ, the valve opening, pipeline back to normal ventilation.

常开型 阀门应用独特的直动式结构，当给电磁头的线圈通电时，位于线圈周围的静铁芯组件便产生磁性，磁力克服阀杆组件重力和回位弹簧弹力后将动铁芯连同阀杆组件向上吸起，从而使固连在阀杆组件上的阀盘与阀座紧密贴紧而密封，阀门关闭；断电后，阀盘在回位弹簧及阀杆组件重力作用下恢复原位，阀门开启，管道恢复正常通气。&Gas solenoid valve works &是由中国电磁阀网提供的国际阀门新闻，译文仅供参考。另外，中国电磁阀网还提供相关产品搜索：电磁阀型号、电磁阀价格、电磁阀技术、电磁阀新闻、电磁阀生产商等。
