进口水下电磁阀 喷泉 跑泉 防水 潜水专用电磁阀 美国RETZ瑞茨

　　品牌：RETZ瑞茨/我们一直致力于流体控制领域的持续创新，始于2005……进口水下电磁阀也称之潜水电磁阀、水下电磁阀、喷泉专用电磁阀，是自动控制系统中常见的开关元件、为音乐喷泉的核心控制设备，特别适用于跑泉、跳泉的水路控制,利用介质压力差工作的直动式电磁阀门，他采用膜片结构，具有启闭迅速、性能稳定、使用方便、可靠性高、寿命长等特点；该阀抗污能力极强，可在江、河、湖、海及各种人工水域中长期使用

　　Underwatersolenoid valves, also known as submersible solenoid valves, underwater solenoidvalves, and fountain specific solenoid valves, are common switching componentsin automatic control systems and the core control equipment for musicfountains. They are particularly suitable for controlling the water path ofrunning springs and jumping springs. Direct acting solenoid valves that utilizemedium pressure differences work. They adopt a diaphragm structure and havecharacteristics such as fast opening and closing, stable performance,convenient use, high reliability, and long service life; This valve has stronganti pollution ability and can be used for a long time in rivers, lakes, seas,and various artificial water bodies

　　进口水下电磁阀工作原理-Workingprinciple of imported underwater solenoid valve

　　常闭式：Normallyclosed

　　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。

　　Whenthe 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 themedium pressure in the lower chamber, and the solenoid valve opens. When thecoil is powered off, the pilot valve core is reset by the spring, the pilothole is closed, and the valve upper chamber is pressurized by the piston orificeand the thrust of the reset spring, and the solenoid valve is closed.
