Coil combination structure and assembling method

Abstract

The present invention discloses a coil combination structure and an assembling method. The coil combination structure comprises a magnetic conductive framework and a cover plate, the magnetic conductive framework and the cover plate are both of cuboid structures, and the magnetic conductive framework is integrally formed; a first mounting hole penetrating through the magnetic conductive framework along the vertical direction is formed in the magnetic conductive framework, and a second mounting hole penetrating through the cover plate along the vertical direction is formed in the middle of the cover plate; a static iron core is in threaded connection in the second mounting hole, the cover plate is fixed to the magnetic conductive framework through a screw assembly, and a coil assembly is mounted in the first mounting hole; the upper end of the coil assembly forwards penetrates out of the magnetic conductive framework and extends to the front side of the magnetic conductive framework, and the lower middle portion of the static iron core is inserted into the coil assembly. The coil combination structure of the invention has the advantages of convenience in processing and positioning, long service life and the like.

Description

technical field [0001] The invention belongs to the technical field of valve bodies, and in particular relates to a coil combination structure and an assembly method. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic. It is an automatic basic component used to control fluid. It belongs to actuator. Solenoid valve is usually composed of coil combination structure and magnetic core and other parts. When the coil is energized or de-energized, the operation of the magnetic core will cause the fluid to pass through the valve body or be cut off, so as to achieve the purpose of changing the direction of the fluid. The coil combination structure in the solenoid valve is very important to the solenoid valve. The magnetic permeable frame manufactured by the traditional coil combination structure is mostly U-shaped and needs to be molded after low-pressure injection molding. The patent application number 201711370805.5 in the prior ar...

The coil combination structure in the solenoid valve is very important to the solenoid valve. The magnetic permeable frame manufactured by the traditional coil combination structure is mostly U-shaped and needs to be molded after low-pressure injection molding. In the prior art, the patent application number 201711370805.5 has an integrally formed The coil combination structure used in the valve of the adjustable double-body tank of the pole piece, the first tank body and the second tank body are connected by threaded connection, which is inconvenient to process, and the end cover of the first tank body has an outward protrusion Therefore, it is necessary to reserve the installation position for installing the electrical connector when processing the first tank body, which is not easy to process and difficult to locate
