Abstract
The utility model discloses an assembly structure of an electronic expansion valve nut bed, which comprises the nut bed and a valve body, wherein the nut bed is arranged in an inner bore of the valve body; the upper end of the inner bore of the valve body is inwards contracted to form a grab; and a clamping part which is matched with the grab is shaped on the outer wall of the nut bed. In the utility model, the nut bed and the valve body can be firmly connected through matching the grab at the upper end of the inner bore of the valve body with the clamping part on the outer wall of the nut bed so as to ensure that the nut bed cannot be separated from the inner bore of the valve body when an electronic expansion valve is under the extreme condition, and the using effect is very good.
Description
Technical field:
The utility model relates to the operation of air conditioning systems technical field, especially relates to a kind of nut seat assembly structure that is used for the electric expansion valve of frequency-conversion air-conditioning system.
Background technique:
Electric expansion valve is by the rotation of electronic driver control step motor rotor, and the transmission by screw thread drives needle and axially moves, thereby regulates the flow area of valve port, reaches the purpose of regulating refrigerant flow.See shown in Figure 1: existing electric expansion valve nut seat assembly structure is that nut seat 01 directly is pressed in valve body 02 endoporus by interference fit, this assembly structure needs the outside dimension of strict control nut seat 01 and the interior hole dimension of valve body 02, in the production process of reality as size Control problem such as bad or fault in material, the electric expansion valve that is assemblied on the air-conditioning breaks away from valve body 02 endoporus because of long-term operation may cause nut seat 01, causes the inefficacy of electronic expansion valve controls function.
The model utility content:
The purpose of this utility model provides a kind of assembly structure of new electric expansion valve nut seat with regard to being the deficiency that exists at prior art, it has rational in infrastructure, can guarantee that electric expansion valve can not break away from the characteristics of valve body inner bore at extreme condition lower nut seat.
For achieving the above object, the assembly structure of electric expansion valve nut seat of the present utility model includes nut seat and valve body, nut seat is installed in the endoporus of valve body, and the formation grab is inwardly shunk in the upper end of described valve body inner bore, and the outer wall of nut seat forms the inserted part that cooperates with grab.
Preferred as technique scheme, described grab is with the lower end transition of cone angle or stepped form and valve body, and its wall thickness is less than the wall thickness of valve body lower end.
Preferred as technique scheme, described inserted part is a step.
Preferred as technique scheme, described inserted part is a groove.
The beneficial effects of the utility model are: the cooperating of the inserted part on its grab by valve body inner bore upper end and the nut seat outer wall, nut seat firmly is connected with valve body, guarantee that electric expansion valve can not break away from valve body inner bore at extreme condition lower nut seat, using effect is very good.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is existing electric expansion valve nut seat assembly structure schematic representation;
Fig. 2 is one of the utility model embodiment's a structural representation;
Fig. 3 is the utility model embodiment's two a structural representation;
Fig. 4 is the utility model embodiment's three a structural representation;
Fig. 5 is the utility model embodiment's four a structural representation;
Fig. 6 is a user mode schematic representation of the present utility model.
Embodiment:
See that Fig. 2 is to shown in Figure 6: the assembly structure of electric expansion valve nut seat of the present utility model includes nut seat 10 and valve body 20, nut seat 10 is installed in the endoporus of valve body 20, the upper end of valve body 20 endoporus is inwardly shunk and is formed grab 21, and the outer wall of nut seat 10 forms the inserted part 11 that cooperates with grab 21.During practical set, at first nut seat 10 is pressed in valve body 20 endoporus, riveting valve body 20 openings make it inwardly to tighten and block nut seat 10 again, avoid nut seat 10 to break away from valve body 20 endoporus.
Inserted part 11 on the nut seat 10 can be groove (as shown in Figure 3) or step (as Fig. 2, Fig. 4, shown in Figure 5); The grab 21 that cooperates with inserted part 11 can cone angle or the lower end transition of stepped form and valve body 20, with the wall thickness at attenuate bending deflection position.
The above only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, and every equalization of doing according to the utility model changes with modifying and all belongs in the claim that the utility model contains.
