[0022] The utility model is further illustrated below in connection with drawings and specific embodiments, and it should be understood that the following specific embodiments are only used to illustrate the utility model and not used to limit the scope of the utility model.

[0023] As Figure 1 And Figure 2 Shown, a kind of automobile built-in air conditioner installation valve core, including valve core end;The valve core end 6 is integrally connected with front end 8 structure, the front end 8 rear end is installed with front connecting section 4, the front connecting section 4 is fixedly connected with rear connecting section 2 by extension section 3, the rear connecting section 2 is fixedly installed on the front end face of rear end 1;

[0024] Example one:

[0025] The extension loading installation process between the front end head 8 and the rear end head 1 can be completed through the extension section 3, and the replacement process of the air conditioner valve core of the adaptive model is adapted. The structure completes the butt joint installation process of the extension section 3 through the front extension section 4 and the rear extension section 2 of the front end head 8 and the rear end head 1. Such a butt joint structure can use the front extension section 4 and the rear extension section 2 as a secondary butt joint end head, avoiding the wear caused by the direct butt joint of the front end head 8 and the rear end head 1, and the need for overall replacement of the valve core structure. Therefore, the structure also has the effect of reducing cost and increasing efficiency.

[0026] The front end head 6 of the valve core end head 6 is provided with a slot 7, the slot 7 is open forward, and the slot 7 is in butt joint with the center of the air conditioner valve seat. The slot 7 is provided to cooperate with the installation of the valve seat.

[0027] As shown in Figure 1 and Figure 2 , the extension section 3 is provided with an extension section butt joint end head 3-2 on both sides of the front and rear, and the extension section butt joint end head 3-2 is a recessed end head. The extension section butt joint end heads 3-2 on both sides of the extension section 3 are inlaidly connected with the conical butt joint end head 11. The recessed end head has the advantage of avoiding external impurities from eroding and interfering.

[0028] As shown in Figure 1 and Figure 2 , the extension section 3 is provided with a ceramic layer 3-1 in the middle; the middle structure of the ceramic layer 3-1 can effectively avoid oxidation corrosion, and the material also meets the industrial use standard.

[0029] As shown in Figure 1 and Figure 2 , the valve core end head 6 is provided with a transverse hole 5 transversely penetrating along the front end head, and the transverse hole 5 is in butt joint with the transverse plug of the valve seat butt joint end head. The transverse hole 5 serves as a positioning and installation structure for the transverse plug, which can further reinforce the connection between the valve seat and the valve core.

[0030] As shown in Figure 1 and Figure 2 , the front end head 8 and the rear extension section 2 are both provided with an operation groove 10 in the middle; the design of the operation groove 10 is to prevent the increase of the installation size of the overall valve core caused by hand grease and impurities, and the design of the operation groove 10 is more convenient for the operator to complete the installation process according to the specified force point.

[0031] The front end head 8 and the rear extension section 2 are provided with a sealing ring 9 between the installation connection sections.

[0032] As shown in Figure 1 and Figure 2As shown, the front end 8 and the rear connecting section 2 are uniformly distributed with several groups of equidistant ring grooves 12 along the taper butt joint end 11 segment position. Among them, the design of the equidistant ring groove 12 can cooperate with the volume expansion problem caused by the temperature change, and the equidistant ring groove 12 can provide expansion space to ensure that the valve core can normally operate within a certain temperature and time period.

[0033] It should be noted that the above only illustrates the technical idea of the present application, and cannot limit the protection scope of the present application. For ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which fall within the scope of the claims of the present application.
