进口防爆螺纹电磁阀 德国洛克防爆螺纹电磁阀

一、进口防爆螺纹电磁阀产品概述：

德国《LOCKE》洛克--进口防爆螺纹电磁阀，imported explosion proof threaded solenoid valve，是把设备可能点燃爆炸性气体混合物的部件全部封闭在一个外壳内，其外壳能够承受通过外壳任何接合面或结构间隙，渗透到外壳内部的可燃性混合物在内部爆炸而不损坏，并且不会引起外部由一种、多种气体或蒸气形成的爆炸性环境的点燃，把可能产生火花、电弧和危险温度的零部件均放入隔爆外壳内，隔爆外壳使设备内部空间与周围的环境隔开。隔爆外壳存在间隙，因电气设备呼吸作用和气体渗透作用，使内部可能存在爆炸性气体混合物。

1、 Introduction of imported explosion proof threaded solenoid valve products:

The imported explosion proof proof threaded solenoid valve is designed to seal all parts of the equipment that may ignite explosive gas mixture in a shell. The shell can withstand the internal explosion of combustible mixture penetrating into the shell through any joint surface or structural gap of the shell without damage, Besides, it will not cause the ignition of the explosive environment formed by one or more gases or vapors. The parts that may produce sparks, arcs and dangerous temperatures are put into the flameproof enclosure, which separates the internal space of the equipment from the surrounding environment. There is a gap in the flameproof enclosure, and there may be explosive gas mixture in the enclosure due to the breathing and gas penetration of electrical equipment.

三、进口防爆螺纹电磁阀工作原理：

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。

常开—当线圈通电时，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。

          当线圈断电时，先导阀芯靠弹簧复位，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。

注—出口端压力大于进口端压力，介质会反向导通。可安装止回阀。

3、 Working principle of imported explosion-proof threaded 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.

LOCKE, Germany -- imported explosion proof threaded solenoid valve, imported explosive proof solenoid valve, is a device that can ignite a mixture of explosive gases all parts enclosed in a shell, the housing is capable of withstanding an internal explosion of combustible mixture that penetrates through any joint or structural gap in the housing without damage, and will not cause the ignition of an external explosive environment formed by one or more gases or vapors, putting the parts that may produce sparks, ARCS and dangerous temperatures into the explosion-proof enclosure, the flameproof enclosure separates the internal space of the equipment from the surrounding environment. There is a gap in the flameproof enclosure, which may contain explosive gas mixture due to the suction and gas permeation of the electrical equipment. Sentence is too long, please supply a shorter sentence, pilot Spool Suction, pilot hole open, relief pressure on the Valve Chamber, Piston Chamber media pressure driven, solenoid valve open. When the coil is cut 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 throttle hole and the thrust of the reset spring, and the solenoid valve is closed. When the coil is energized, the pilot core is reset by the spring, the pilot hole is closed, the upper chamber is pressurized by the Piston throttling hole and the thrust of the reset spring, and the solenoid valve is closed. When the coil is cut off, the pilot spool is reset by spring, the pilot hole is opened, the upper chamber of the valve is unloaded, the Piston is driven by the lower chamber medium pressure, and the solenoid valve is opened. Note the pressure at the outlet is greater than that at the inlet and the medium is turned on in the opposite direction. Installable check valve.
