Embodiment Construction

[0042] This part is the embodiment of the present invention, which is used to explain and illustrate the technical solution of the present invention.

[0043] A method for fixing a double coil of an electromagnetic valve, comprising the following steps:

[0044] Step 1: Cut an insulating tape of appropriate size and wind at least one layer on the valve assembly 1;

[0045] Step 2, prepare at least two insulating gaskets 2, apply insulating varnish on all the insulating gaskets 2, and attach the insulating gaskets 2 to the left end surface and the right end surface of the valve assembly 1 respectively;

[0046] Step 3, install the retaining ring 5 on the valve assembly 1, and the retaining ring 5 is used to isolate the double coil;

[0047] Step 4, place the block 15 at the position of the second coil 14 to fix the retaining ring 5, and then wind the first coil 13;

[0048] Step 5, remove the stopper 15, and then wind the second coil 14, the second coil 14 is wound into a tra...

Abstract

The invention belongs to the technical field of electromagnetic valves, and discloses an electromagnetic valve double-coil fixing method. An insulating tape is wound on a valve assembly, an insulating spacer is pasted on the valve assembly and the like are carried out in advance, then double coils of an electromagnetic valve are wound by using a special method, and meanwhile, the position and the form of a leading-out wire meet certain requirements. The double-coil electromagnetic device wound through the method has the advantages of being compact in structure, small in size and higher in reliability, and leading-out wires are not prone to falling off.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic valves, and relates to a method for manufacturing an electromagnetic valve, in particular to a method for fixing double coils of an electromagnetic valve. Background technique [0002] As an important control element of the aviation hydraulic system, the reliability requirements of the solenoid valve are continuously improved with the development and improvement of the hydraulic system, and are developing in the direction of miniaturization and light weight. The traditional solenoid valve coil structure has a large volume and weight, and the welding part of the lead wire and the enamelled copper round wire takes up a lot of space, the solder joints are not reliably protected, the tensile force that can be tolerated is small, and the reliability of the lead wire fixing is low. The traditional solenoid valve coil structure can no longer meet the requirements of miniaturization, light weight ...
