The structure of valve core case 18 is specifically introduced below in conjunction with Fig. 2 and Fig. 3, valve core case 18 entirety cylindrically structure, it is internally formed valve core case chamber 181, valve core case 18 is fixedly connected by the cooperation of upper end periphery wall and nut 15 bottom internal perisporium, the connector that the bottom of valve core case 18 is offered by valve seat 10 bottom inserts in discharge connection 13, and valve core case 18 bottom periphery wall is fixedly connected by the inwall of the modes such as welding with valve seat 10 lower end connector and discharge connection 13.Valve core case 18 is provided with through hole 183, and through hole 183 is in order to through valve support chamber 101 and valve core case chamber 181.nullThe bottom of valve core case 18 is further opened with fluid and flows out chamber，Specifically this fluid outflow chamber includes the first outlet plenum 184 and installation portion，First outlet plenum 184 upper end is spool mouth 182，Fluid flows into overall the first outlet plenum 184 in loudspeaker taper from valve core case chamber 181 through spool mouth 182，The installation portion being integrally formed through with the first outlet plenum 184 it is additionally provided with below this first outlet plenum 184，Specifically this installation portion is made up of the first receiving portion 185 and the second receiving portion 186，And second the diameter of receiving portion 186 bigger than the diameter of the first receiving portion 185，First receiving portion 185 top is formed with the first auxiliary section 1851，First receiving portion 185 sidewall is formed with the second auxiliary section 1852，First auxiliary section 1851 also serves as the lower end bottom surface sections of the first outlet plenum 184 simultaneously.
Further, this electric expansion valve also includes silencing means 19, below in conjunction with specifically introducing silencing means 19 shown in Fig. 4.
nullThe profile for silencing means 19 shown in Fig. 4，Silencing means 19 in the present embodiment is that integral net is poroid or ring-type piece of part of cellular，Specifically by metal wire braiding in netted、Thread、Spongy or the wire netting of cavernous structure，Or wire netting forms the multi-ply construction of sintered meshwork by sintering，This silencing means 19 includes circumference, top 191 and external side wall 192，Specifically this silencing means 19 matches with the cavity shape of the first receiving portion 185，Wherein circumference, top 191 abuts against with the first auxiliary section 1851，External side wall 192 abuts against with the second auxiliary section 1852，Pass through riveting、The modes such as welding are fixed in the first receiving portion 185，Certainly silencing means 19 can also be the sub-assembly being coated with mesh or vesicular texture，This silencing means 19 can also is that other shapes in addition to bulk，Should be noted that the material specifically presented for silencing means 19 and shape are not construed as the restriction that the utility model is described.
Further, this electric expansion valve also includes pad 20, when silencing means 19 is fixed, can be by the bottom of riveting valve core case 18 so that it is deformation, pad 20 is fixed on valve core case 18, thus pad 20 is fixed in the second receiving chamber 186, meanwhile, circumference, top 191 and the external side wall 192 of silencing means 19 are connected on the first auxiliary section 1851 of the first receiving portion 185 and the second auxiliary section 1852 firmly, thus realize fixing in the first receiving portion 185.
Mode except riveting, it is also possible to use the mode of welding, will be welded and fixed with valve core case 18 by pad 20；Or make between pad 20 and valve core case 18 by interference press-fit, can realize silencing means 19 is fixed on the purpose in valve core case 18.In addition, not using pad 20 when, also can be by the bottom of riveting valve core case 18, make it deform thus directly silencing means 19 is fixed in the first receiving portion 185, this is no longer going to repeat them to relate to concrete fixed setting method, it should be noted that according to set forth above, during regardless of whether use pad, can realize silencing means 19 is fixed on the purpose in valve core case 18.
It should be noted that in the present embodiment, valve core case 18 is integrated parts, and in actual process, it is also possible to valve core case 18 is set to split-type structural, i.e. the upper cartridge with through hole 183 and the bottom with spool mouth 182；Additionally; fit system between valve core case 18 with valve seat 10, adapter 13 can also make the various replacement means being equal to; this is not defined by the embodiment disclosed in the utility model, it will be appreciated by those skilled in the art that these shift meanses also belong to protection domain of the present utility model.
According to electric expansion valve described above, under coil magnetization energization action, rotor 14 rotates, and drive screw mandrel 16 to be rotated, by the screw thread pair effect between screw mandrel 16 and nut 15, screw mandrel 16 rotate time carry out the elevating movement on axially, so that needle 17 opens or closes spool mouth 182 to regulate the flow of fluid simultaneously.
nullDuring low discharge regulation in the early stage，Needle 17 from completely close spool mouth 182 to slowly open spool mouth 182 low discharge regulate during，Significantly throttling can be produced because aperture is less at spool mouth 182，Now fluid enters valve support chamber 101 from inlet tube 12，Enter valve core case chamber 181 by the through hole 183 of valve core case 18 again to be flowed out by spool mouth 182，Flow through the fluid that spool oral area divides significantly to be accelerated and the vortex of sound of being similar to scream that CF occurs，The mesh being now provided with because of installation portion below spool mouth 182 or cavernous silencing means 19，Fluid flows out discharge connection 13 via this silencing means 19，Now fluid is by multilayer mesh effect，The eddy current that this silencing means 19 can will be formed、Bubble can fully stir and dissipate or smash，Thus reduce abnormal sound，Improve client further and use comfort，A kind of electric expansion valve that the utility model provides simultaneously is all easier to realize for structure or technique，By the silencing means 19 arranged below spool mouth 182，The source produced from noise is optimized design，Meet the demand also being able to inhibit abnormal sound to produce when carrying out low discharge regulation.
A kind of electronic expansion valve structure provided by the utility model is described in detail.Principle of the present utility model and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; on the premise of without departing from the utility model principle, it is also possible to the utility model is carried out some improvement and modification, these improve and modification also falls in the utility model scope of the claims.
