进口PTFE电磁阀美国RETZ品牌

品牌：RETZ瑞茨/我们一直致力于流体控制领域的持续创新，始于2005……进口防腐蚀电磁阀采用聚四氟乙烯/PTFE为原材料,几乎适用于各种化学、酸碱、盐酸、硝酸、醋酸等腐蚀性介质管道作自动化控制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;

进口PTFE电磁阀工作原理--Working principle of imported PTFE solenoid valve

常闭式：当线圈通电时，先导阀芯吸合，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。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.
