進(jìn)口超高溫電磁閥│帶散熱片高溫電磁閥│耐700℃超高溫電磁閥
【應(yīng)用范圍】
它廣泛應(yīng)用于船舶重工、測試設(shè)備、加熱設(shè)備、液壓設(shè)備等,工作溫度在300℃以上的導(dǎo)熱系統(tǒng)中。
產(chǎn)品特點(diǎn):
技術(shù)、耐溫設(shè)計(jì);活塞結(jié)構(gòu)、性能穩(wěn)定;材料、密封性好;專制線圈、不易燒毀。
建議:線圈選用脈沖控制或自保持式控制。
【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,閥關(guān)閉。

How it works:
NC: When the coil is energized, the pilot spool pull the pilot hole to open, pressure relief valve, piston push media pressure on the lower chamber, the electromagnetic valve is opened; When the coil power, the pilot valve by the spring return, pilot hole Close the valve on the throttle chamber pressurized by the piston return spring and thrust, the valve 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.
