An electromagnetic valve

Abstract

The application discloses an electromagnetic valve, which comprises a valve body, a coil, wherein the valve body comprises a mounting groove, the coil comprises a clamping spring, the clamping spring is partially located in the mounting groove, the clamping spring is limitedly matched with the coil, the mounting groove comprises an opening part, a first groove wall and a second groove wall, the second groove wall is located above the first groove wall, the first groove wall limits the downward displacement of the clamping spring, the second groove wall limits the upward displacement of the clamping spring, the opening part is located on the outer side wall of the valve body, the second groove wall is arranged in a conical surface, along the longitudinal direction of the electromagnetic valve, the included angle between the surface where the second groove wall is located and the surface where the transverse direction of the electromagnetic valve is located is defined as A, and 5° < A ≤ 20° is met, and the second groove wall gradually increases towards the opening part. The mounting groove of the electromagnetic valve can limit the pulling force of the clamping spring of the coil, and the stability of the product is improved.
