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.
