Abstract

A two-position and two-way electromagnetic valve comprises a valve body and a valve element. The valve element can be arranged in an inner cavity of the valve body in a vertical sliding manner. An air inlet and an air outlet are formed in the side edge of the valve body. The air inlet and the air outlet are arranged in parallel in the height direction. A ventilation groove is formed in the side face of the valve element in the circumferential direction. The upper end of the valve element is connected with the lower end of an elastic element. The upper end of the elastic element is connected with a coil used for driving the valve element to slide upwards after electrification, and the coil is fixed to the upper portion of the inner cavity of the valve body. In the electrification state of the coil, the height of the ventilation groove is consistent with the height of the air inlet and the height of the air outlet, the ventilation groove communicates with the air inlet and the air outlet, and in the non-electrification state of the coil, the height of the ventilation groove is smaller than that of the air inlet and that of the air outlet. The two-position and two-way electromagnetic valve high in adjusting precision is provided.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a two-position two-way solenoid valve. Background technique [0002] As we all know, the solenoid valve is an automatic basic component used to control the direction of the fluid. It belongs to the actuator and has a two-position switch action. The existing research on pneumatic high-speed switching valves focuses on the two-position two-way type, mainly on the cut-off pneumatic switching valve, and less research on the slide valve type pneumatic valve. The existing two-position two-way solenoid valve has the defect of low adjustment accuracy. Therefore, improvements are required. Contents of the invention [0003] In order to overcome the disadvantage of low adjustment precision of the existing two-position two-way solenoid valve structure, the present invention provides a two-position two-way solenoid valve with high adjustment precision. [0004] The technical solution ado...
