品牌:RETZ瑞茨/我們一直致力于流體控制領(lǐng)域的持續(xù)創(chuàng)新,始于2005……進(jìn)口先導(dǎo)式電磁閥比較適合大口徑場合,高壓力工況下使用,需要注意的是,流通的介質(zhì)-定要大于0.03Mpa的壓力才能正確使用本產(chǎn)品廣泛應(yīng)用于蒸汽系統(tǒng),高壓系統(tǒng),低溫系統(tǒng),工業(yè)石油供用系統(tǒng),灌裝系統(tǒng),液化氣系統(tǒng),供熱系統(tǒng),儲(chǔ)灌設(shè)備,電廠設(shè)備,石化設(shè)備,氣動(dòng)設(shè)備,管道自控等自動(dòng)化裝置retz The pilot operated solenoid valve is more suitable for large diameter occasions and high pressure conditions. It should be noted that the circulating medium must be greater than 0.03Mpa to use correctly. This product is widely used in steam systems, high-pressure systems, low-temperature systems, industrial oil supply systems, filling systems, liquefied gas systems, heating system, storage and irrigation equipment, power plant equipment, petrochemical equipment, pneumatic equipment, pipeline automation and other automation devices
注解-
1.流體中若含有雜質(zhì),電磁閥進(jìn)端必須安裝過濾閥(精度40—200目),
2.電磁閥安裝方位無限制。(S-水平安裝、C-垂直安裝)
3.無粘稠,無凝固及結(jié)晶現(xiàn)象。
由先導(dǎo)閥和主閥芯聯(lián)系形成通道組合而成動(dòng)作可靠,間接開關(guān),在有壓力的情況下正常工作 The combination of a channel formed by the connection between the pilot valve and the main valve core is reliable in action, with an indirect switch that operates normally under pressure
大通徑,多種密封形式可選 Large diameter, multiple sealing forms available
進(jìn)口先導(dǎo)式電磁閥控制原理--
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。
