Abstract
The utility model provides an anti-noise structure of an automobile air-conditioning thermostatic expansion valve, comprising a transmission part and a valve core. The anti-noise structure is characterized in that the bottom part of the transmission part is provided with a fixing groove; and the top end of the valve core is tightly combined with the transmission part by the fixed groove. The anti-noise structure leads a transmission mechanism and the valve core mechanism to be tightly combined, has a certain positioning function, further prevents the thermostatic expansion valve from generating joggling phenomenon in the operating process and improves the problem of noise of an automobile air-conditioning system.
Description
Technical field
The utility model relates to a kind of automobile air-conditioning heating power expansion valve its anti-noise structure, can be used for improving car air conditioner and in use produces the noise phenomenon, belongs to the automobile air-conditioning heating power expansion valve technical field of structures.
Background technique
Shown in Figure 1A, traditional automobile air-conditioning heating power expansion valve structure comprises transmission part 1 and spool 2, and the bottom of transmission part 1 directly contacts with spool 2 tops.Shown in Figure 1B, the shortcoming of this structure is that the slippage shake can take place spool 2 in the course of the work, thereby produces bigger noise.
Summary of the invention
The purpose of this utility model provides a kind of automobile air-conditioning heating power expansion valve structure of difficult generation slippage shake.
In order to achieve the above object, the technical solution of the utility model has provided a kind of automobile air-conditioning heating power expansion valve its anti-noise structure, comprises transmission part and spool, it is characterized in that, bottom at transmission part has fixed groove, combines closely in the top of fixed groove and spool.
The utility model can be combined closely driving mechanism and spool mechanism, and certain positioning action is arranged, and then prevents that heating power expansion valve from jitter phenomenon not taking place in operation, and then improves the automotive air-conditioning system noise problem.
Description of drawings
Figure 1A is former automobile air-conditioning heating power expansion valve structural representation;
Figure 1B is a schematic representation after the displacement of Figure 1A;
A kind of automobile air-conditioning heating power expansion valve its anti-noise structure schematic representation that Fig. 2 provides for the utility model;
Fig. 3 is the partial enlarged drawing of I part among Fig. 2.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figures 2 and 3, a kind of automobile air-conditioning heating power expansion valve its anti-noise structure for the utility model provides has fixed groove 3 in the bottom of transmission part 1, and the top of spool 2 and fixed groove 3 are combined closely.The fixed groove regulation: transmission part 1 matches with spool 2 tops.
Because, by driving fixed groove 3 in the bottom of transmission part 1, the bottom of spool 2 tops and transmission part 1 is closely cooperated, make spool 2 can not produce the slippage shake at the volley, on existing mature technology basis, carry out, keep the product previous condition as far as possible, reduce technical risk, and can guarantee product performance, can solve the heating power expansion valve noise problem simultaneously.
Claims (1)
