进口防爆电磁阀 Imports explosion-proof solenoid valve
进口防爆电磁阀|进口防爆电磁阀【进口防爆电磁阀】优点：Imports explosion-proof solenoid valve | imports of explosion-proof solenoid valve【Import proof solenoid valve】 advantages:
1、防爆电磁阀工作寿命长。
explosion-proof solenoid valve long working life.
2、防爆电磁阀工作制式：分*工作制，反复短时工作制和短时工作制三种。防爆电磁阀均为*工作制，即线圈允许*通电工作。对于长时间阀门开通只有短时关闭的情况，则宜选用常开电磁阀。用在短时工作制而批量又很大时，可作特殊订货以降低功耗。
Explosion-proof solenoid valve working standard: points of long-term work, repeated short-time work and short-time working system of three. Proof solenoid valves are long-term work system, that coil to allow long-term power. For a long time the valve opening only short-term closure, you should use normal open solenoid valve. In short-time work in large quantities when you can make a special order to reduce power consumption.
3、防爆电磁阀工作频率：动作频率要求高时，结构应优选直动式电磁阀，电源听优选交流。
The explosion-proof solenoid valve operating frequency: the frequency of demanding action, the structure should preferably direct acting solenoid valve, the power to listen to the exchange preferred.
进口防爆电磁阀概述：
Overview of imports explosion-proof solenoid valve
进口防爆电磁阀适用于易燃易爆介质，以及对爆炸性危险场所管路介质的自动切换。如天然气、煤气、液化气等气体或其它流体。隔爆型防爆形式是一种具有隔爆外壳的电气设备。进口防爆电磁阀隔爆外壳能承受已进入外壳内部的可燃性混合物内部爆炸而不损坏，并且通过外壳上的任何接合面或结构孔不会引燃一种或多种气体或蒸气所形成的外部爆炸性环境的电气设备。进口防爆电磁阀有两种形式，一种是常闭式，常闭：当线圈通电时，电磁铁芯吸合，卸压孔打开，主活塞由介质压力推动，打开主阀口，介质流通。一种常开式，当线圈通电时，电磁铁芯吸合，卸压孔关闭，主活塞由介质压力推动，关闭主阀口，介质截止。
Import proof solenoid valves are suitable for inflammable and explosive medium, and automatically switch on the explosive hazardous locations pipeline media. Such as natural gas, coal gas, liquefied gas or other fluid. The explosion-proof form of a flameproof enclosures of electrical equipment. The imported proof solenoid valve flameproof enclosure can withstand an internal explosion of the combustible mixture to enter the interior of the housing without damage, and through any joints or structural holes in the housing does not ignite one or more gases or vapors formed by the external electrical equipment for explosive environments. Imports of explosion-proof solenoid valve has two forms, one is normally closed and normally closed: when the coil is energized, the electromagnet core pull, pressure relief hole to open the main piston driven by medium pressure, open the main valve port, media circulation. A normally open when the coil is energized, the electromagnet core pull relief hole is closed, the main piston driven by medium pressure, turn off the main valve port, media cutoff.
进口防爆电磁阀故障排除：
Imports explosion-proof solenoid valve troubleshooting:
一、电磁阀通电后不工作 Solenoid valve is energized not working
检查电源接线是否不良→重新接线和接插件的连接 检查电源电压是否在±工作范围-→调致正常位置范围 线圈是否脱焊→重新焊接 线圈短路→更换线圈 工作压差是否不合适→调整压差→或更换相称的电磁阀 流体温度过高→更换相称的电磁阀 有杂质使电磁阀的主阀芯和动铁芯卡死→进行清洗,如有密封损坏应更换密封并安装过滤器 液体粘度太大，频率太高和寿命已到→更换产品
Check power wiring is bad → re-wiring and connectors connected Check power supply voltage operating range is within ± - → tone range coil to the normal position Desoldering → ??re-welded coil short circuit → Replace the coil operating pressure differential is inappropriate → adjust the differential pressuresolenoid valve fluid temperature is too high →→ or replace commensurate replace the solenoid valve commensurate impurities so that the main spool of the solenoid valve and movable core stuck → cleaning, if the seal is broken should replace the seal and install filter liquid viscosity is tootoo often, and life has to → replacement products
二、电磁阀不能关闭 Solenoid valve can not be closed
主阀芯或铁动芯的密封件已损坏→更换密封件 流体温度、粘度是否过高→更换对口的电磁阀 有杂质进入电磁阀产阀芯或动铁芯→进行清洗 弹簧寿命已到或变形→更换 节流孔平衡孔堵塞→及时清洗 工作频率太高或寿命已到→改选产品或更新产品
The seals of the main spool or iron moving core damage → Replace the seal fluid temperature, the viscosity is too high → impurities into the solenoid valve production spool or moving core → replacement the counterparts of electromagnetic valve cleaning spring life or deformation→ Replace the throttle the Kong Pingheng the holes clogged → timely cleaning too often or life to the → reelection products or updated product
三、其它情况 Other cases
内泄漏→检查密封件是否损坏,弹簧是否装配不良 外泄漏→连接处松动或密封件已坏→紧螺丝或更换密封件 通电时有噪声→头子上坚固件松动，拧紧。电压波动不在允许范围内，调整好电压。铁芯吸合面杂质或不平，及时清洗或更换。
Internal leakage → Check the seals for damage, spring assembly adverse external leakage → connections loose or the seal has been broken → screws or replace the seal energized the noise → chieftain sturdy pieces loose, tighten. Voltage fluctuation is not within the allowable range, adjust the voltage. Core pull the occlusal surface impurities or uneven, timely cleaning or replacement.
