Background technique
Electromagnetic switching valve is the important devices of heat pump type air conditioner, is applicable to central authorities, detachable air conditioner etc.The action of existing electromagnetic switching valve is the height pressure reduction utilizing in system, utilizes the conversion of the electromagnetic coil power on/off state of control valve, realizes the switching to the stream of main valve body 1, and then realizes the transformation that in system, refrigerant flows to.Control valve is connected by fixing frame 6 with main valve body 1.Existing fixing frame 6 adopts two ends riveted joint, exists riveted joint distortion large, the technical problems such as riveting process complexity, and with the fitment stability of control valve valve body 2 a little less than, riveted joint efficiency is lower, processing cost is high.Therefore be necessary to be improved.
Summary of the invention
The deficiency existing for prior art, the object of this invention is to provide a kind of electromagnetic switching valve, and its riveting process is easy, and fitment stability is good, and manufacturing efficiency is high, and processing cost is relatively low.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of electromagnetic switching valve, comprise main valve body, the fixing frame of control valve valve body and Integral mold Blanking Shaping, the first side of fixing frame is provided with a snap ring type fixing frame, middle part is provided with connection bracket, the second side is provided with a circular hole fixing frame, snap ring type fixing frame and circular hole fixing frame stand upright on respectively the both sides of connection bracket, snap ring type fixing frame, connection bracket and circular hole fixing frame are connected, connection bracket or snap ring type fixing frame are fixed on main valve body, control valve valve body is arranged in circular hole fixing frame near a side of valve end, the opposite side that is connected with conduit is fixed on snap ring type fixing frame.
Further, in technological scheme, described snap ring type fixing frame comprises the first sheet material, and the lower end of the first sheet material is linked to connection bracket, and on sheet material, stamping-out has the clasp of a side mouth.
Further, in technological scheme, described circular hole fixing frame comprises the second sheet material, and the lower end of the second sheet material is linked to connection bracket, and the second sheet material offers a manhole corresponding to the position of clasp.
Further in technological scheme, the central axis of described manhole is parallel and a little less than the central axis of the control valve valve body after fixing.
Further, in technological scheme, described control valve valve body is provided with cylindrical stage stage structure in the position near end, and described ledge structure is arranged in circular hole fixing frame.
Further, in technological scheme, the external diameter of described ledge structure is less than described manhole.
Further, in technological scheme, on described ledge structure, be provided with annular groove, described annular groove is embedded in through hole.
Further, in technological scheme, the groove width of described annular groove is greater than the thickness of described the second sheet material.
Adopt after said structure, the advantage that compared to the prior art the present invention had is: in the situation that not changing main valve body and control valve valve body agent structure, by optimizing fixed rack structure, be simplified to fix frame processing technology, both sides snap ring type fixing frame is made into clasp one side, one side circular hole formula fixing frame as positioning control valve body structure simultaneously, avoided because fixing frame distortion in riveted joint process is bad and the unstable product causing of locating bias is bad, simplified riveting process complexity, larger improving production efficiency, save control valve valve body raw material utilization rate simultaneously, guarantee control valve valve body and main valve body setting height(from bottom), improving product consistency of performance, reduce production costs.

Embodiment
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Snap ring type fixing frame 3 comprises the first sheet material, and the lower end of the first sheet material is linked to connection bracket 4, and on sheet material, stamping-out has the clasp of a side mouth.Circular hole fixing frame 5 comprises the second sheet material, and the lower end of the second sheet material is linked to connection bracket 4, the second sheet materials and offers a manhole 51 corresponding to the position of clasp.
The central axis of manhole 51 is parallel and a little less than the central axis of the control valve valve body after fixing.Control valve valve body 2 is provided with cylindrical stage stage structure 52 in the position near end, and ledge structure 52 is arranged in circular hole fixing frame 5.Control valve valve body 2 when mounted, first ledge structure 52 is stretched in manhole 51, due to the central axis of manhole 51 central axis a little less than control valve valve body 2, therefore, when mounted, control valve valve body 2 slightly tilts, now that 3 riveted joints of snap ring type fixing frame are fixing, because the external diameter of ledge structure 52 is less than manhole 51, under the effect of rivet force, manhole 51 forms inscribed circle with ledge structure 52, now, control valve valve body 2 axes recovery levels, and control valve valve body 2 is fastening with fixing frame 6.
As embodiment 2, to compare with embodiment 1, difference is: on cylindrical stage stage structure 52, be provided with circular groove structure again, groove structure is embedded in manhole, during installation, control valve valve body, by circular hole fixing frame 5 axial limitings, can effectively prevent that control valve valve body 2 from axial dipole field occurring.
Fixing frame 6 of the present invention adopts the structure of snap ring type fixing frame 3, one side circular hole fixing frame 5 on one side, avoided because 6 distortion of fixing frame in riveted joint process are bad and the unstable product causing of locating bias is bad, simplified riveting process complexity, larger improving production efficiency, the valve body raw material utilization rate of simultaneously saving control valve, reduces production costs.Simplified riveting process complexity, larger improving production efficiency is saved guide valve blocks raw material utilization rate simultaneously, guarantees control valve valve body 2 and main valve body 1 setting height(from bottom), and improving product consistency of performance, reduces production costs.
Above content is only preferred embodiment of the present invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, for example, on the basis of manhole, be transformed into the structure shapes such as semi-circular hole or the half side rectangle of half side circle, all belong to invention thought of the present invention, this description should not be construed as limitation of the present invention.
