品牌：RETZ/我们一直致力于流体控制领域的持续创新，始于2005……进口真空电磁阀通常用于真空设备管路作通断,本产品广泛应用在工业炉窑、干燥设备、制药机械、真空设备、制药、水厂虹吸管路、航天、石油化工、电力装备、钢铁、电镀涂装、燃气燃油、环保设备、酿酒、吹灰除尘、纺织印染、暖通空调、食品、水处理、等控制系统等工作压力为负压的管道系统中Retz vacuum solenoid valve is usually used for on-off of vacuum equipment pipelines. This product is widely used in industrial furnaces, drying equipment, pharmaceutical machinery, vacuum equipment, pharmaceutical, water plant siphon pipelines, aerospace, petrochemical, power equipment, steel, electroplating and coating, gas fuel, environmental protection equipment, brewing, dust removal, textile printing and dyeing, HVAC, food, water treatment, and other control systems with negative working pressure in pipeline systems
进口真空电磁阀工作原理--Working principle of imported vacuum 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 is opened, the upper chamber of the valve is depressurized, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened; 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.
