Description
Technical field
The utility model belongs to refrigeration accessory technical field, and automobile air-conditioning heating power expansion valve especially low with a kind of cost, that stability is high, outward appearance is good is relevant.
Background technique
Because current rearmounted vaporizer still cannot replace with the H type heating power expansion valve of inner equilibrium formula, F type heating power expansion valve just becomes the essential throttling arrangement of domestic and international rearmounted vaporizer, be characterized in outer balance, interior temperature-sensitive and be quick on the draw, can meet the requirement of car air conditioner to antidetonation, efficient and aspect easy to assemble.Yet traditional outer balance type vehicle air conditioner heating power expansion valve has adopted old-fashioned argon arc welding machine at air tank head weld, causes deficient manufacturing procedure rate too high, and product appearance is bad, and stability is poor.And itself also adopt copper product, greatly increased cost of production.
Model utility content
The purpose of this utility model is exactly to overcome existing heating power expansion valve to exist the defect that the life-span is short, stability is poor, and the automobile air-conditioning heating power expansion valve that a kind of life-span is long, stability is high is provided.
For this reason, the utility model by the following technical solutions: a kind of automobile air-conditioning heating power expansion valve, comprises gas tank seat, top cover, valve body, balance tube, drive link, diaphragm, valve ball, valve ball seat, pressure spring and spring seat, one end of balance tube is inserted in the mounting hole at top cover top, and the other end of balance tube is connected with temperature-sensitive bag, top cover, diaphragm and gas tank seat adopt the laminating of resistance soldering encapsulation technology to weld together from top to down, have reduced reject ratio and the cost of product, put forward high performance stability, drive link, valve ball, valve ball seat, pressure spring and spring seat pack in the inner chamber of valve body from top to down successively, the lower end of valve body is connected with liquid storage device for drying and filtering, the right side outlet of valve body is connected with vaporizer, temperature-sensitive bag is arranged on the outlet conduit of vaporizer, it is characterized in that: described automobile air-conditioning heating power expansion valve also comprises skull, between described diaphragm and gas tank seat, be provided with skull, the upper end of drive link is connected with this skull, increased and diaphragm between surface of contact, greatly improve the stability of performance, also extended the working life of heating power expansion valve.
Working principle of the present utility model: when the temperature rising of evaporator outlet refrigeration agent, will make the upward pressure of diaphragm increase, the drive link that promotes skull below increases expansion valve opening, strengthens the flow of refrigeration agent in vaporizer, refrigerating capacity is increased, and vice versa.
As to technique scheme further supplement and perfect, the utility model also comprises following supplementary technology scheme:
Described skull is arranged to round platform, and the large straight lower surface through round platform end and diaphragm is fitted and connected, and small-diameter circular you is connected with the upper end of drive link.
The flat board of punching press projection in the middle of described skull also can be set as, dull and stereotyped raised face (RF) is connected with the upper end of drive link, and the reverse side of dull and stereotyped projection and the lower surface of diaphragm are fitted and connected.
Use the utility model can reach following beneficial effect: the utility model is provided with skull between diaphragm and gas tank seat, increased and diaphragm between surface of contact, greatly improved the stability of performance, also extended the working life of heating power expansion valve.
