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)口油用電磁閥采用先導(dǎo)閥、活塞組合的結(jié)構(gòu)設(shè)計(jì),適用于導(dǎo)熱油、潤(rùn)滑油、機(jī)油、柴油、汽油等常溫介質(zhì)在管路中的自動(dòng)啟閉，從而達(dá)到系統(tǒng)和設(shè)備的程序控制或遠(yuǎn)程控制The RETZ oil solenoid valve is designed with a combination of pilot valve and piston structure, suitable for automatic opening and closing of normal temperature media such as heat transfer oil, lubricating oil, engine oil, diesel, gasoline, etc. in pipelines, thus achieving program control or remote control of the system and equipment
進(jìn)口油用電磁閥控制原理--
常閉：normal close
當(dāng)線圈通電時(shí)，先導(dǎo)閥芯吸合，先導(dǎo)孔打開(kāi)，閥上腔卸壓，活塞靠下腔介質(zhì)壓力推動(dòng)，電磁閥打開(kāi)。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
