品牌：RETZ瑞茨/我們一直致力于流體控制領(lǐng)域的持續(xù)創(chuàng)新，始于2005……進(jìn)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(guān)狀態(tài)的閥門,適合用于需檢測介質(zhì)是否流動的自動化管道系統(tǒng),本產(chǎn)品廣泛應(yīng)用在石油化工、工業(yè)爐窯、鍋爐、給排水、采暖空調(diào)、消防設(shè)備、干燥設(shè)備、食品設(shè)備、醫(yī)療設(shè)備、清洗設(shè)備、景觀噴灌、石化、電力、化學(xué)、輕工、機(jī)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(jìn)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(dāng)線圈通電時，先導(dǎo)閥芯吸合，先導(dǎo)孔打開，閥上腔卸壓，活塞靠下腔介質(zhì)壓力推動，電磁閥打開。當(dāng)線圈斷電時，先導(dǎo)閥芯靠彈簧復(fù)位，先導(dǎo)孔關(guān)閉，閥上腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力，電磁閥關(guān)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(dāng)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(dāng)電磁閥關(guān)閉時，信號公共線和關(guān)信號線接通 When the solenoid valve is closed, the signal common line and the off signal line are connected
