        Military industry, nuclear industry, shipbuilding, petrochemical, power, chemical, light industry, machinery, scientific research, industrial furnace, gas pipeline, pipeline medium automation control field.

        進口防爆電磁閥技術參數(Imported electromagnetic valve technical parameters)
        產品規格:DN1~DN500
        閥體材質:鑄鐵、不銹鋼 (304、316)
        溫度范圍:-100~+450℃
        適用介質:易燃易爆液體或氣體
        防護性能:防水、防腐 、防爆(Exd IICT5)
        控制方式:常開、常閉
        電源電壓:AC(380、240、220、24)V、DC(110、24)V
        連接方式:螺紋、法蘭
        泄漏量:零

        Product specifications: DN1~DN500

        Body material: cast iron, stainless steel ( 304, 316)

        Temperature range: -100~+450

        Applicable medium: flammable liquids or gases

        Protective performance of waterproof, anti-corrosion, explosion-proof: ( Exd IICT5 )

        Control mode: normally open, normally closed

        Power supply voltage: AC ( 380, 240, 220, 24) V, DC ( 110, 24) V

        Connection: thread, flange

        Leakage: Zero



        進口防爆電磁閥工作原理(Imported electromagnetic valve working principle)

        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,閥上腔由活塞節流孔增壓和復位彈簧的推力,電磁閥關閉。

        Normally closed: when the coil is energized, the pilot valve is open, pilot hole, cavity pressure relief valve on the piston cavity, rely on medium pressure to promote, the solenoid valve opens.

        When the coil is de-energized, the pilot valve core by the reset spring, the pilot hole is closed by the piston, valve chamber orifice pressurizing and reset spring thrust, the electromagnetic valve is closed.

        When the coil is de-energized, the pilot valve core by the reset spring, the pilot hole is opened, the valve cavity pressure relief, pressure to push the piston cavity medium, the solenoid valve opens.
