二、進(jìn)口低溫電磁閥工作原理：

常閉：當(dāng)線圈通電時(shí)，先導(dǎo)閥芯吸合，先導(dǎo)孔打開，閥上腔卸壓，活塞靠下腔介質(zhì)壓力推動(dòng)，電磁閥打開；當(dāng)線圈斷電時(shí)，先導(dǎo)閥芯靠彈簧復(fù)位，先導(dǎo)孔關(guān)閉，閥腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力，電磁閥關(guān)閉。

When the pressure of the pilot valve core is opened, the solenoid valve is closed by the pressure of the solenoid valve.

Normally open: when the coil is energized, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the return 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 released, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.

三、進(jìn)口低溫電磁閥結(jié)構(gòu)特點(diǎn)：

1、經(jīng)過低溫深冷處理，能耐-196℃低溫

2、獨(dú)特設(shè)計(jì)、壽命超長、性能穩(wěn)定、密封性好、開關(guān)迅速。

3、獨(dú)特設(shè)計(jì)、外觀精美；活塞結(jié)構(gòu)、性能穩(wěn)定；低溫材料、密封性好專制線圈、不易燒毀。

4、閥芯均為不銹鋼活塞式,活塞環(huán)用特殊耐低溫、耐磨材料制作:活塞與金屬閥腔不產(chǎn)生直接摩擦,閥體安裝方向無限制；特制線圈,不易燒毀；長時(shí)間停止動(dòng)作重新啟動(dòng),作同樣靈敏。

1. After cryogenic treatment, it can withstand - 196 ℃ low temperature

2. Unique design, long service life, stable performance, good sealing and quick switching.

3. Unique design, beautiful appearance; piston structure, stable performance; low temperature material, good sealing performance, autocratic coil, not easy to burn.

4. The valve core is stainless steel piston type, and the piston ring is made of special low temperature resistant and wear-resistant materials: the piston and metal valve chamber do not have direct friction, the installation direction of the valve body is unlimited; the special coil is not easy to burn; it stops and restarts for a long time, which is equally sensitive.
