Embodiment Construction

[0030] image 3 The electromagnetic coil shown is mainly composed of a skeleton 11, a winding 12, a magnetically conductive sleeve 13, a magnetically conductive body 14, an insulating coating 15, and a lead wire 16 (or insert), wherein:

[0031] The frame 11 is in the shape of a circular tube, with an inner hole 11a in its center, and folded edges 11c at both ends, so that a winding winding accommodation is formed between the folded edges to stabilize the wound winding; the two ends of the frame 11 are self-connecting The hole 11b expands outward to form a positioning portion 11b;

[0032] The magnetic sleeve 13 is also in the shape of a round tube, its outer diameter matches the inner hole 11a, and one end is provided with an end flange 13b, the size of which end flange can just be located in the positioning portion 11b of the aforementioned skeleton and be aligned with the skeleton. The end faces are basically flat;

[0033] The winding 12 is a wire wound on the skeleton 1...

Abstract

A magnet coil of solenoid valve consists of insulation covering substance, winding being packaged on frame, magnetic conductive body set at external of insulation covering substance, lead wire terminal being configured outwards from said winding and magnetic conductive sleeve set in internal hole of said frame.

Description

technical field [0001] The invention is an electromagnetic coil for an electromagnetic valve used in a heat pump air conditioner. Background technique [0002] The structural principle of the existing solenoid valve scheme is as follows: figure 1 As shown, it consists of three parts: electromagnetic coil, pilot valve and main valve. Its structure and working principle are described as follows: [0003] The main valve includes a cylindrical valve body 31, on which there is a discharge connection D (that is, a high-pressure area) connected to the compressor discharge port, and a suction connection S (that is, a high-pressure area) connected to the compressor suction port. The connecting pipe E connected with the indoor heat exchanger, the connecting pipe C connected with the outdoor heat exchanger, the two ends of the valve body are sealed with end caps 34, the valve seat 36 is welded inside, and the connecting rod 32 The integrated slide block 35 and a pair of pistons 33, t...
