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)口水下電磁閥也稱之潛水電磁閥、水下電磁閥、噴泉專用電磁閥，是自動(dòng)控制系統(tǒng)中常見的開關(guān)元件、為音樂噴泉的核心控制設(shè)備，特別適用于跑泉、跳泉的水路控制,利用介質(zhì)壓力差工作的直動(dòng)式電磁閥門，他采用膜片結(jié)構(gòu)，具有啟閉迅速、性能穩(wěn)定、使用方便、可靠性高、壽命長等特點(diǎn)；該閥抗污能力極強(qiáng)，可在江、河、湖、海及各種人工水域中長期使用

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(jìn)口水下電磁閥工作原理-Working principle of imported underwater solenoid valve

常閉式：Normally closed

當(dāng)線圈通電時(shí)，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(dòng)，電磁閥打開。當(dāng)線圈斷電時(shí)，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。

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.
