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)口高溫電磁閥為先導(dǎo)活塞式結(jié)構(gòu),采用杠桿散熱功能，原理*證線(xiàn)圈和閥體徹底隔離,，提高了使用溫度,，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(chǎng)合、中高溫?zé)崴?、中高溫?dǎo)熱油,、高溫蒸汽、過(guò)熱蒸汽等,、電站抽氣管道疏水系統(tǒng)和蒸發(fā)器的排氣需要高溫控制的系統(tǒng)中The RETZ high-temperature electromagnetic valve is a pilot piston type structure that uses a lever heat dissipation function to ensure complete isolation between the coil and valve body, increasing the operating temperature. It is widely used in bottle blowing machinery, air compressors, humidification equipment, high-temperature and high-pressure occasions, medium to high temperature hot water, medium to high temperature heat transfer oil, high-temperature steam, superheated steam, etc., as well as in systems that require high-temperature control for the drainage system of power station extraction pipelines and the exhaust of evaporators

進(jìn)口高溫電磁閥工作原理--Working principle of imported high-temperature solenoid valve

常閉式：當(dāng)線(xiàn)圈通電時(shí),，先導(dǎo)閥芯吸合，先導(dǎo)孔打開(kāi),，閥上腔卸壓,，活塞靠下腔介質(zhì)壓力推動(dòng)，電磁閥打開(kāi),。 當(dāng)線(xiàn)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.

Note: If the outlet pressure is greater than the inlet pressure, the medium will conduct in the opposite direction. Can be installed with a check valve
