RETZ/我們一直致力于流體控制領域的持續創新，始于2005……進口高壓電磁閥通常為活塞式結構,廣泛應用于吹瓶機械、空壓機、加濕設備、高溫高壓場合、中高溫熱水、導熱油、高溫蒸汽、飽和蒸汽及過熱蒸汽等需要高壓控制的系統中 The Retz high-pressure solenoid valve is usually a piston type structure and is widely used in systems that require high-pressure control, such as bottle blowing machinery, air compressors, humidification equipment, high-temperature and high-pressure occasions, medium and high temperature hot water, thermal oil, high-temperature steam, saturated steam, and superheated steam, etc
進口高壓電磁閥工作原理--Working principle of imported high-pressure solenoid valve
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.

注：出口端壓力大于進口端壓力，介質會反向導通。可安裝止回閥。
