進口低溫電磁閥 液化氣 液氨 液氮 LNG空分專用電磁閥的簡單介紹

進口低溫電磁閥 液化氣 液氨 液氮 LNG空分專用電磁閥的詳細(xì)信息

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……進口超低溫電磁閥的閥桿為加長型,本產(chǎn)品通常用于LNG、液氧、乙醛、液氮、液氨、石油液化氣、天然氣、濾油機等易燃易爆等管路作自動化控制The valve stem of RETZ ultra-low temperature solenoid valve is an extended type. This product is usually used for automatic control of flammable and explosive pipelines such as LNG, liquid oxygen, acetaldehyde, liquid nitrogen, liquid ammonia, liquefied petroleum gas, natural gas, oil filters, etc.

液體、氣體、油品可混合使用，提高閥的使用范圍Liquid, gas, and oil can be mixed for use, increasing the range of use of the valve

進口超低溫電磁閥工作原理--

常閉式：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。

Normally closed: When the coil is energized, the pilot valve core is closed, the pilot hole opens, the upper chamber of the valve is depressurized, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens. When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, and the valve upper chamber is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.
