Embodiment Construction

[0017] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.

[0018] Such as figure 1 As shown, a solenoid valve core structure for enhancing electromagnetic force according to the present invention includes a moving iron core 1 and a fixed iron core 2 forming an electromagnetic path with the moving iron core 1, and a sealing rubber is arranged on the moving iron core 1 3. The sealing rubber 3 is used to seal with the moving iron core 1 during work. The side of the moving iron core 1 is provided with two transverse ventilation holes 4 perpendicular to each other, and a blind hole for ventilation is opened in the center of the moving iron core 1. 5. The center of the fixed iron core 2 is provided with a vent hole 6, the edge of the end face of the moving iron core 1 is provided with a chamfer 7, and the end face of the fixed iron core 2 is provided...

Abstract

The invention discloses an electromagnetic valve core structure with an enhanced electromagnetic force. The electromagnetic valve core structure with the enhanced electromagnetic force comprises a movable core and a fixed core forming an electromagnetic passage with the movable core, wherein sealing rubber is arranged on the movable core; the sealing rubber is used for sealing the movable core in the working process; two transverse vent holes which are perpendicular to each other are formed in the side surface of the movable core; a ventilating blind hole is formed in the center of the movable core; vent holes are formed in the center of the fixed core; a chamfer is arranged on the edge of the end surface of the movable core; a conical groove matched with the chamfer on the edge of the end surface of the movable core is arranged on the end surface of the fixed core. The edge of the end part of the movable core is designed to be a shape of a chamfer, and the fixed core and the movable core are matched with each other through the chamfer and the groove, so that flux area is increased, a magnetic air gap is decreased, the electromagnetic force is enhanced, and the problem that the startup voltage of the electromagnetic valve is high is solved; the conical groove is easy to manufacture, the chamfering process is good, and the production process is easy to control.

Description

technical field [0001] The invention belongs to the technical field of solenoid valves, and relates to a solenoid valve for an automobile engine system, in particular to a solenoid valve iron core structure for enhancing electromagnetic force. Background technique [0002] At present, solenoid valves are widely used in automobile engine systems as auto parts. In the automobile engine system, through the opening and closing of the solenoid valve, the intake air volume of the gas circuit system is controlled to ensure the normal operation of the engine. During this process, the work of the solenoid valve is controlled by the electrical signal sent by the ECU. The iron core is the core component of the solenoid valve. If the design is not reasonable, the solenoid valve will not be able to open and close normally under the electrical signal sent by the ECU, thus affecting the performance of the vehicle. [0003] In the existing solenoid valve, the magnetic flux surface of the ...
