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)口防腐蝕電磁閥采用聚四氟乙烯/PTFE為原材料,幾乎適用于各種化學(xué)、酸堿、鹽酸、硝酸、醋酸等腐蝕性介質(zhì)管道作自動(dòng)化控制The Retz anti-corrosion solenoid valve uses polytetrafluoroethylene/PTFE as the raw material, and is almost suitable for automatic control of various corrosive media pipelines such as chemical, acid-base, hydrochloric acid, nitric acid, acetic acid, etc;

進(jìn)口PTFE電磁閥工作原理--Working principle of imported PTFE solenoid valve

常閉式：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。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.
