Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as any limitation to the present invention.

[0026] see Figure 1-Figure 4 : The present invention is mainly made up of coil cover 1, coil 2, pole shoe assembly 3, spring 4, armature assembly 5, ejector rod 6 and valve body 7.

[0027] During the assembly process, the coil 2 and the coil cover 1 are successively put on the pole shoe assembly 3, and the right end of the coil cover 1 and the pole shoe assembly 3 are welded and fixed; then the ejector rod 6 is installed into the armature assembly 3 and then together with the spring 4 Press into the pole shoe assembly 3, and finally press the valve body 7 into the pole shoe assembly 3, after the left end of the valve body 7 and the pole shoe assembly 3 are welded and fixed, the assembly of the entire valve assembly is completed.

[0028] Such as figure 2 As shown, the pole shoe assembly 3 is compo...

Abstract

The invention discloses a micro normally closed electromagnetic valve with two-stage gag bit structures. The micro normally closed electromagnetic valve mainly consists of a coil cover (1), a coil module (2), a pole shoe module (3), a spring (4), a gag bit module (5), an ejector rod (6) and a valve body (7). In the assembly process, the coil (2) and the coil cover (1) sleeve the pole shoe module (3) in succession; the right end of the coil cover (1) is fixedly welded with the pole shoe module (3); after the ejector rod (6) is mounted in the gag bit module (5), the ejector rod (6) and a springare pressed into the pole shoe module (3); finally, the valve body (7) is pressed into the pole shoe module; and the valve body (7) and the pole shoe module (3) are fixed through electronic beam welding to finish assembly of a whole valve assembly. The electromagnetic valve adopts split two-stage gag bit structures to improve the opening electromagnetic force of the electromagnetic valve; and under the same performance indexes, the volume and the mass of the electromagnetic valve are about 50% of that of a traditional electromagnetic valve.

Description

technical field [0001] The invention relates to a miniature electromagnetic valve, in particular to a two-position, two-position normally closed miniature electromagnetic valve with a two-stage armature structure. Background technique [0002] The fuel adjustment system in the hydraulic system has the advantages of simple structure, high reliability, and good environmental adaptability. In aviation, aerospace, ships and some special fields, the fuel adjustment system has been widely used. Especially in the aerospace field, the solenoid valve is an important control element of the hydraulic system, and its reliability requirements are continuously improved with the development and improvement of the hydraulic system, and it is developing in the direction of miniaturization and light weight. Moreover, the micro solenoid valves currently on the domestic market basically rely on imports. Contents of the invention [0003] The object of the present invention is to provide a mi...
