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……進口襯氟電磁閥是將聚四氟乙烯樹脂采用模壓(或鑲嵌)方法置于鑄鋼或不銹鋼閥體內壁的表面，復位彈簧、動鐵芯等金屬件設置在介質外，與腐蝕性流體完全隔離，利用其在抗強腐蝕介質方面的獨特性能制做成襯四氟電磁閥可耐各種強酸(98%濃硫酸，王水)強堿、強氧化劑及有機溶劑，實現了真正的耐腐蝕retz The fluorine lined solenoid valve is made by placing polytetrafluoroethylene resin on the surface of the inner wall of a cast steel or stainless steel valve body using a molding (or embedding) method. Metal parts such as reset springs and moving iron cores are placed outside the medium, completely isolated from corrosive fluids. By utilizing its unique characteristics in resisting strong corrosive media, the fluorine lined solenoid valve can withstand various strong acids (98% concentrated sulfuric acid, aqua regia), strong alkalis, strong oxidants, and organic solvents, achieving true corrosion resistance
襯氟電磁閥工作原理Working principle of fluorine lined solenoid valve
常閉-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
