Abstract
The utility model discloses a vacuum solenoid valve, which comprises a coil support. A through hole is formed in the coil support. A mandrel I is embedded into the lower part of the through hole, and is a fixed valve element. A sealing ring is clamped outside the mandrel I to ensure seal between the mandrel I and the inner wall of the coil support. A movable valve element is embedded into the upper part of the through hole. A gap is formed between the movable valve element and the inner wall of the coil support. A plug is embedded into the center of the movable valve element, penetrates through the upper and lower ends of the movable valve element, and is positioned over a shaft hole of the mandrel I. The upper end of the through hole is connected with a mandrel II and a mandrel III. A shaft hole of the mandrel II is positioned over the plug. The mandrel III is perpendicular to the mandrel II. A necking part is arranged at the lower end of the movable valve element and the upper end of the mandrel I. The two ends of a spring are sleeved on and pressed against the necking part respectively. A coil is wound outside the coil support. A shell is arranged outside the coil. The vacuum solenoid valve has the advantages of low machining cost, good sealing effect and long service life.
