進(jìn)口高壓電磁閥 美國RETZ品牌

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)口高壓電磁閥通常為活塞式結(jié)構(gòu),廣泛應(yīng)用于吹瓶機(jī)械、空壓機(jī)、加濕設(shè)備、高溫高壓場合、中高溫?zé)崴?dǎo)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(tǒng)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(jìn)口高壓電磁閥工作原理--working principle of imported high-pressure solenoid valve
常閉式：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。
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.
