Description
Affiliated technical field
The present invention relates to the mortor operated valve on refrigeration systems such as air conditioner, refrigerating machine, installed and used, especially relate to a kind of at stator for the mortor operated valve that has characteristics aspect the fixation arrangement of housing.
Background technique
Installing and using existing mortor operated valve on this air conditioner, refrigerating machine etc. is the machinery of adjustment refrigerant fluid flow, generally include have its through with valve chamber in valve seat contact the valve body that passes through flow that the needle that leaves is adjusted fluid; Be fixed on the housing on the valve body; Be installed in the housing, the rotation that stator is produced magnetic field formation changes into the rotor that needle contacts, leaves valve seat; Its outer being contained on the housing, the central part that drives said rotor rotation has the stator of through hole to constitute,
Figure 13 and Figure 14 are an example of a kind of typical mortor operated valve in the existing technology.Figure 13 is the exploded perspective view of mortor operated valve, and Figure 14 is this mortor operated valve stereogram after the expression assembling.With respect to the valve body 1 loading and unloading coil device (stator) 3 of assembling freely, on being fitted to housing 1a after, adopt circumferential clasp 2 to be fixed on the valve body 1, this circumferential clasp 2 has 6 resilient 2c of department of assembly.Embed among the pilot hole 2b that is formed at annular body 2a and welding through the boss 3a that is provided with on the stator 3; Thereby circumferential clasp 2 is fixed on the stator 3; Stator 3 constitutes: with respect to housing 1a, on the circumference of housing 1a, can select any in the 6 places assembling attitude.Through such structure, when setting mortor operated valve in the refrigeration cycle, can select assembling attitude with respect to the optimal stator 3 of the other side's machine.
Specifically, will be chimeric through 4 projection 1b on embedding hole 2d that forms and the peripheral parts that form housing 1a such as stamping-out, thus being fixed in the mortor operated valve side to stator 3, said embedding hole 2d is formed on 6 2c of department of assembly that are fixed on the stator 3.The diameter of embedding hole 2d that is formed at the 2c of department of assembly is slightly littler than the diameter of the root of the projection 1b on the peripheral part that is formed on housing 1a; Stator 3 is positioned with respect to the housing 1a of mortor operated valve main body thus; Through such structure; Two 2c of department of assembly of symmetry that are formed with embedding hole 2d push housing 1a across projection 3, and other the 2c of department of assembly that is formed with embedding hole 2d directly pushes housing 2, and stator 3 is positioned and is fixed with respect to housing 2 thus.
Yet, having the above-mentioned location and the mortor operated valve of fixation arrangement, 4 projections on the described housing peripheral part are very near because of the shrinking away from theshell end of body; Cause the shell end distortion during manufacturing easily, influence the welding quality of shell ends oral area next procedure argon arc welding, secondly; 4 projection practical implementations on the housing peripheral part are that punching press such as punch press distortion is shaped and forms, and forming process is prominence wall thickness attenuation, simultaneously with the stator assembling after; As repeatedly loading and unloading, exist projection is galled or wear down, cause the risk of leakage.
Summary of the invention
