品牌：RETZ/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)口水用電磁閥通常采用先導(dǎo)式結(jié)構(gòu),適用于中性純凈氣體或液體、水、熱水、冷凍水、循環(huán)水、除鹽水、海水等管路的自動化控制系統(tǒng),從而達(dá)到系統(tǒng)和設(shè)備的程序控制或遠(yuǎn)程控制The RETZ water solenoid valve usually adopts a pilot type structure and is suitable for automatic control systems of neutral pure gas or liquid, water, hot water, chilled water, circulating water, desalinated water, seawater, and other pipelines, in order to achieve program control or remote control of the system and equipment.
進(jìn)口水用電磁閥控制原理--
常閉型：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，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Normally closed type: When the coil is energized, the pilot valve core is closed, the pilot hole is opened, the upper chamber of the valve is depressurized, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened; 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.
