Description

Technical Field

[0001] This utility model belongs to the field of valve seat technology, specifically relating to a high-temperature resistant and deformation-resistant filling valve seat for automotive air conditioning. Background Technology

[0002] The charging valve seat is a component of the automotive air conditioning charging valve, which is a valve used for vacuuming and refrigerant charging in automotive air conditioning systems. It typically consists of a valve body, valve core, and valve cap. As part of the valve body, the charging valve seat's main function is to connect the refrigerant circuit and the refrigerant charging device, ensuring that refrigerant can be smoothly and safely charged into the automotive air conditioning system.

[0003] As a crucial component of automotive air conditioning systems, the charging valve seat's technology has continuously evolved with the changing refrigerants. Traditional charging valve seats may have some shortcomings, such as insufficient sealing performance and susceptibility to damage, problems that become more pronounced with the use of new refrigerants. Therefore, technological improvements and innovations in charging valve seats are particularly important. Summary of the Invention

[0004] Based on the above, this application provides a high-temperature resistant and deformation-resistant filling valve seat for automotive air conditioning that is resistant to deformation, has strong balance, and a simplified structure.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A high-temperature resistant and deformation-resistant filling valve seat for automotive air conditioning includes a base; the base has a vertically oriented mounting hole at its center; a disc seat is recessed at the upper center of the base; a guide sleeve is vertically mounted at the top center of the disc seat; a valve seat end is fitted around the outer ring of the guide sleeve; a retainer is mounted on the neck of the valve seat end; the retainer has radially distributed support bodies; and the bottom support of the retainer is mounted on the upper surface of the disc seat.

[0007] Furthermore, the plate base includes an upper plate base and a lower plate base; a first groove is retained between the upper plate base and the lower plate base.

[0008] Furthermore, the bottom end face of the lower plate seat is chamfered, and the chamfered end face of the lower plate seat makes guide contact with the base.

[0009] Furthermore, the lower plate seat has a cavity along its center.

[0010] Furthermore, the valve seat end includes a bottom end and a top end;

[0011] A second groove is provided between the bottom end and the top end, and the lowest horizontal plane of the second groove is flush with the top horizontal plane of the cage.

[0012] Furthermore, the retainer has a groove along its bent end.

[0013] The beneficial effects of this utility model are as follows:

[0014] Compared with existing technologies, this utility model adopts a cage structure to assist in the positioning and balancing support of the valve seat end at the top of the valve body, ensuring the overall stability of the valve body structure and preventing valve body misalignment during use, which would reduce sealing performance. At the same time, the overall structure is simplified, and the cage effectively suppresses valve body structural displacement caused by high-temperature deformation. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0020] like Figure 1 and Figure 2 As shown, a high-temperature resistant and deformation-resistant filling valve seat for automotive air conditioning includes a base. The base 1 has a vertically oriented mounting hole at its center. A disc seat is recessed into the upper center of the base 1. A guide sleeve 11 is vertically mounted at the top center of the disc seat. A valve seat end is fitted around the outer ring of the guide sleeve 11. A retainer 6 is mounted on the neck of the valve seat end. The retainer 6 has radially distributed support structures, and its bottom frame 7 supports the upper surface of the disc seat. The base 1 serves as the main support for the overall valve seat, guiding and supporting the disc seat, adapting to subsequent vacuum environment operations. The valve seat end fitted by the guide sleeve 11 is a second guiding support structure, which, together with the third guiding support structure of the top retainer 6, further maintains the structural stability of the valve seat. Simultaneously, the support structure of the retainer 6 can further control the offset of local deformation of the valve seat end caused by temperature changes.

[0021] like Figure 1 and Figure 2As shown, the plate holder includes an upper plate holder 12 and a lower plate holder 13; a first groove 9 is provided between the upper plate holder 12 and the lower plate holder 13. The design of the first groove 9 is to add a sealing ring to maintain an internal vacuum environment.

[0022] like Figure 1 and Figure 2 As shown, the bottom end face of the lower plate seat 13 is chamfered, and the chamfered end face of the lower plate seat 13 makes guiding contact with the base 1. The chamfer design serves as a guiding contact.

[0023] like Figure 1 and Figure 2 As shown, the lower plate base 13 has a cavity 8 along its center. The design of the cavity 8 can save local materials and also reduce the chamfer area, avoiding unevenness at the bottom end face that could cause the frame to tilt.

[0024] like Figure 1 and Figure 2 As shown, the valve seat end includes a bottom end 5 and a top end 4;

[0025] A second groove 10 is provided between the bottom end 5 and the top end 4, and the lowest horizontal plane of the second groove 10 is flush with the top horizontal plane of the retainer 6. The design of the second groove 10 allows for the addition of a limiting device or a sealing ring, etc., to achieve a positioning effect.

[0026] like Figure 1 and Figure 2 As shown, the retainer 6 has a groove along its bent end. This groove ensures smooth bending of the retainer 6 and reduces the difficulty of the bending operation.

[0027] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
