進口防爆燃氣電磁閥產(chǎn)品簡介：

進口防爆燃氣電磁閥是指用在燃氣管線上，有防爆功能的，緊急切斷，常開或者常閉式電磁閥。

進口防爆燃氣電磁閥工作原理：

常閉：當線圈通電時，先導閥芯吸合，先導孔打開，閥上腔卸壓，活塞靠下腔介質(zhì)壓力推動，電磁閥打開。
     當線圈斷電時，先導閥芯靠彈簧復位，先導孔關閉，閥上腔由活塞節(jié)流孔增壓和復位彈簧的推力，電磁閥關閉。

注：出口端壓力大于進口端壓力，介質(zhì)會反向?qū)?。可安裝止回閥。

Working principle of imported explosion-proof gas solenoid valve:
Normally closed: when the coil is energized, the pilot valve core is closed, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.
When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.
Normally open: when the coil is energized, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.
When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.
Note: if the outlet pressure is greater than the inlet pressure, the medium will conduct reversely. Check valves can be installed.
