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……進口帶信號反潰功能電磁閥是一種能反映電磁閥是處于開或關狀態的閥門,最適合用于需檢測介質是否流動的自動化管道系統,本產品廣泛應用在石油化工、工業爐窯、鍋爐、給排水、采暖空調、消防設備、干燥設備、食品設備、醫療設備、清洗設備、景觀噴灌、石化、電力、化學、輕工、機械等自動化控制RETZ solenoid valve with signal anti collapse function is a valve that can reflect whether the solenoid valve is in an open or closed state. It is most suitable for automated pipeline systems that need to detect the flow of media. This product is widely used in petrochemical, industrial furnaces, boilers, water supply and drainage, heating and air conditioning, fire equipment, drying equipment, food equipment, medical equipment, cleaning equipment, landscape irrigation, petrochemical, power, chemical, light industry, etc Mechanical and other automation control

進口帶信號反饋電磁閥工作原理--Working principle of imported solenoid valve with signal feedback

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.

信號反饋：Signal feedback

當電磁閥打開時，信號公共線和開信號線接通 When the solenoid valve is opened, the signal common line and the open signal line are connected

當電磁閥關閉時，信號公共線和關信號線接通 When the solenoid valve is closed, the signal common line and the off signal line are connected
