Underwater solenoid valves, also known as submersible solenoid valves, underwater solenoid valves, and fountain specific solenoid valves, are common switching components in automatic control systems and the core control equipment for music fountains. They are particularly suitable for controlling the water path of running springs and jumping springs. Direct acting solenoid valves that utilize medium pressure differences work. They adopt a diaphragm structure and have characteristics such as fast opening and closing, stable performance, convenient use, high reliability, and long service life; This valve has strong anti pollution ability and can be used for a long time in rivers, lakes, seas, and various artificial water bodies
進口水下電磁閥工作原理-Working principle of imported underwater solenoid valve
常閉式：Normally closed
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。
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.
