進(jìn)口超低溫電磁閥
美國(guó)米勒(MILLER)品牌：進(jìn)口超低溫液氮電磁閥|-196℃電磁閥主要使用于制冷劑,液態(tài)二氧化碳,液氨,液氧,液氮,氟里昂等低溫流體的管路上，是設(shè)備系統(tǒng)控制中氣體、液體、油類等各種管道介質(zhì)的自動(dòng)化控制，實(shí)現(xiàn)節(jié)能和程序控制自動(dòng)化。是自動(dòng)控制系統(tǒng)中常見的管路開關(guān)元件，被廣泛使用于冷凍庫(kù)、石油化工、暖通空調(diào)、消防、冶金、紡織、船舶重工、環(huán)保及其他各工業(yè)部門的管路裝置中。
產(chǎn)品特點(diǎn)：
1、采用原裝密封材料，壽命是同類產(chǎn)品十倍
2、數(shù)控機(jī)床加工，確保電磁閥的精度與可靠性
3、液體、氣體、油品可混合使用，提高閥的使用范圍
4、采用塑封線圈，提高閥的可靠性并能防水、防潮
5、現(xiàn)場(chǎng)可自由安裝；動(dòng)作響應(yīng)迅速；閥體采用熱鍛成型工藝、外型美觀
6、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(zhǎng)時(shí)間停止動(dòng)作重新啟動(dòng)，作同樣靈敏
7、安裝提示：線圈豎直向上，也可根據(jù)需要任意安裝
主要技術(shù)參數(shù)：
產(chǎn)品規(guī)格： | DN0.5～DN100 |
閥體材質(zhì)： | 不銹鋼 |
適用介質(zhì)： | 液氮、氣、油、蒸汽、腐蝕流體等 |
溫度范圍： | -200～+150℃ |
介質(zhì)粘度： | 小于50C St(大于時(shí)需定制） |
防護(hù)性能： | 防潮、防爆（Exd IICT5)、防腐 |
接線方式： | 接線座式；引線式；插頭式 |
控制方式： | 常開、常閉 |
電源電壓： | DC24～127V; AC36～380V |
連接方式： | 內(nèi)螺紋、法蘭（外螺紋和特殊接口可定做或加轉(zhuǎn)接頭） |
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，閥上腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力，電磁閥關(guān)閉。

Applications:
It is widely used in aerospace, shipbuilding Heavy Industry, chemical, refrigeration equipment, Medical equipment, food refrigeration piping systems.
Features:
Spool is stainless steel piston, piston ring with a special low temperature resistant, wear-resistant material; the piston and the metal does not produce direct friction valve chamber, valve mounting direction unlimited; special coil, not easy to burn; a long time to stop action to re-start, for the same sensitivity.
Main technical parameters:
Specifications: | DN0.5～DN100 DN0.5 ~ DN100 |
Body material: | Stainless Steel |
Medium: | Liquid nitrogen, gas, oil, steam, corrosive fluids |
Temperature range: | -200 ~ +150 ℃ |
Media Viscosity: | Less than 50C St (greater than the time to be customized) |
Protection performance: | Moisture-proof, explosion-proof (Exd IICT5), anti-corrosion |
Wiring: | Terminal Block Type; lead type; male |
Control: | Normally open, normally closed |
Power supply voltage: | DC24 ~ 127V; AC36 ~ 380V |
Connection: | Thread, flange (male and special interfaces or add custom adapter) |
How it works:
NC: When the coil is energized, the pilot spool pull the pilot hole to open, pressure relief valve on the chamber, the piston on the lower chamber medium pressure to promote, the electromagnetic valve is opened; When the coil power, the pilot valve by the spring return, pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed.
Normally Open: When the coil is energized, the pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed. When the coil power, the pilot valve by the spring return, pilot hole open, pressure relief valve on the chamber, medium pressure piston push the lower chamber, the electromagnetic valve is opened.
Note: The outlet pressure is greater than the inlet pressure, the media will pass anti-wizard. Can be installed or custom built non-return valve function of the valve.
