The structure of existing electric expansion valve comprises valve body and coil two parts, and the lower end of valve body is inserted in the endoporus of coil, and the upper end of valve body is positioned at the outside of coil, and the upper end of valve body is provided with longitudinal adapter and laterally takes over.For the ease of being connected of valve body and coil, the fixed head of outwardly convex can be set conventionally on the shell of coil, by fixed head, spacer is fixed on the shell of coil, finally realize the axial location of valve body and coil and circumferential location by spacer again.Adopt aforesaid way to connect valve body and comparatively complexity of loop construction, between fixed head and spacer and spacer and the shell of coil, need to be connected by riveted joint or welding manner, its production technology is comparatively complicated, so just make electric expansion valve production efficiency step-down in process of production, production cost increases.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of expanding valve body fixed structure simple in structure, easy to assembly.
For achieving the above object and other relevant objects, the utility model provides a kind of plug-in expanding valve body fixed structure, comprise valve body and coil, the lower end of described valve body is inserted in the endoporus of described coil, the upper end of described valve body is provided with one and longitudinally takes over and a laterally adapter, the shell of described coil is provided with a stator with horizontal grab, and described horizontal adapter is connected in described horizontal grab.
Preferably, outer shell rivething or the welding of described stator and coil.
Preferably, the shell of described coil is provided with one deck plastic housing, and described stator is fixedly connected with described plastic housing.
Preferably, described stator is connected or ultrasonic bonding with described plastic housing hot melt.
As mentioned above, plug-in expanding valve body fixed structure of the present utility model has following beneficial effect: on the shell of this expanding valve body fixed structure direct-on-line circle, stator is set, block the horizontal adapter of valve body by the horizontal grab on stator, so just can make the axial location of valve body and coil and circumferentially locate, valve body is fixedly connected with coil, valve body structure assembles very quick, can effectively increase work efficiency.This expanding valve body fixed structure is easy to assembly, can effectively enhance productivity, and reduces production costs; Plastic housing is set on the shell of coil and can also prevents the original metal shell corrosion of coil, the service life that can effectively improve expansion valve; Plastic housing can also play the effect that suppresses noise simultaneously, the noise can effectively reduce electric expansion valve work time.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this description.
Refer to Fig. 1 to Fig. 4.Notice, appended graphic the illustrated structure of this description, ratio, size etc., all contents in order to coordinate description to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop in the scope that technology contents that the utility model discloses will contain.Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
As shown in Figure 1, 2, the utility model provides a kind of plug-in expanding valve body fixed structure, this fixed structure comprises valve body 1 and coil 2, the lower end of valve body 1 is mainly the magnet rotor part of electromagnetic expanding valve, the upper end of valve body 1 is provided with one and longitudinally takes over 11 and one laterally adapters 12, because the mechanism of valve body 1 is prior art, therefore be not described in detail at this.The lower end of valve body 1 is inserted in the endoporus of coil 2, so just can control by the magnetic field of coil 2 rotational angle of magnet rotor, and then controls the aperture of magnetic valve, and the shell of coil 2 is provided with inlet wire groove 3, and outer lead can carry out groove 3 and is connected with coil 2 through this.On the shell of coil 2, be provided with a stator 4, stator 4 adopts the mode of welding or riveted joint to be fixedly connected with the shell of coil 2.On stator 4, with horizontal grab 41, the horizontal adapter 12 of valve body 1 is connected in this horizontal grab 41.
