Abstract

The invention discloses a magnetic exchange valve which comprises an armature (1), a coil (2), a push rod (4), a valve core (5) and a valve body (7), wherein the push rod (4) and the valve core (5) are mounted inside the valve body (7), the push rod (4) is connected with the valve core (5), the armature (1) is mounted at the top of the push rod (4), and the coil (2) is mounted at the lower end of the armature (1). According to the magnetic exchange valve provided by the invention, the cross section area of a runner is increased, the liquid flow is increased, and parameters of an electromagnet are changed, so as to reduce power dissipation and increase direction-changing frequency.

Description

technical field [0001] The invention relates to an electromagnetic reversing valve. Background technique [0002] In the prior art, the electromagnetic reversing valve used in the hydraulic system is mainly composed of valve body, valve core, spring, electromagnet and other parts, which mainly solve the start, stop and direction control of the hydraulic actuator. There are common shortcomings such as oil leakage and low commutation frequency. Contents of the invention [0003] The object of the present invention is to provide an electromagnetic reversing valve.
