進(jìn)口水用電磁閥

德國萊克LIK品牌：進(jìn)口水用電磁閥應(yīng)用范圍：它廣泛應(yīng)用在航天、船舶重工、石油化工、工業(yè)爐窯、鍋爐、給排水、采暖空調(diào)、消防設(shè)備、干燥設(shè)備、食品醫(yī)療設(shè)備、清洗設(shè)備、景觀噴灌、水廠等管道系統(tǒng)中。p>

產(chǎn)品特點：
先導(dǎo)式結(jié)構(gòu)，閥芯均為不銹鋼活塞，活塞環(huán)不會被介質(zhì)中的雜質(zhì)卡死，動密封性能高,壽命長；活塞與金屬閥腔不產(chǎn)生直接摩擦，閥體安裝方向無限制；專制線圈，不易燒毀；長時間停止動作重新啟動，動作同樣靈敏；泄漏量零；使用壽命長達(dá)100萬次以上。

主要技術(shù)參數(shù)：

工作原理：
常閉：當(dāng)線圈通電時，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，電磁閥打開；當(dāng)線圈斷電時，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, petrochemical, industrial furnaces, boilers, plumbing, heating and air conditioning, fire fighting equipment, drying equipment, food and medical equipment, cleaning equipment, landscape irrigation, water and other piping systems. p> p>

Features:
Pilot structure, the spool is stainless steel piston, piston rings will not be stuck impurities in the medium, dynamic sealing performance and long life; piston valve chamber with the metal does not produce direct friction, the valve mounting direction unlimited; authoritarian coil and difficult to burn; long restart action to stop the action as sensitive; leakage is zero; life of up to 100 million times.

Main technical parameters:

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, the piston on the lower chamber medium pressure to promote the solenoid valve open.

Size:

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.
