This product is widely used in industrial furnaces, drying equipment, pharmaceutical machinery, vacuum equipment, pharmaceutical, water plant siphon pipelines, aerospace, petrochemical, power equipment, steel, electroplating and coating, gas fuel, environmental protection equipment, brewing, dust removal, textile printing and dyeing, HVAC, food, water treatment, and other control systems with negative working pressure in pipeline systems

進(jìn)口真空電磁閥工作原理--Working principle of imported vacuum solenoid valve

常閉式：當(dāng)線圈通電時，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，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 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.
