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
進口真空電磁閥工作原理--Working
principle of imported vacuum solenoid valve
常閉式：當線圈通電時，先導閥芯吸合，先導孔打開，閥上腔卸壓，活塞靠下腔介質壓力推動，電磁閥打開；當線圈斷電時，先導閥芯靠彈簧復位，先導孔關閉，閥上腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉。
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.
