品牌：RETZ瑞茨/我們一直致力于流體控制領域的持續創新，始于2005……進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、酸堿、鹽酸、硝酸、醋酸等腐蝕性介質管道作自動化控制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;
進口PTFE電磁閥工作原理--Working principle of imported PTFE solenoid valve
常閉式：當線圈通電時，先導閥芯吸合，先導孔打開，閥上腔卸壓，活塞靠下腔介質壓力推動，電磁閥打開。當線圈斷電時，先導閥芯靠彈簧復位，先導孔關閉，閥上腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉。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.
