[0037] Please refer to Figures 1-4 This embodiment provides a sealing structure 100, which includes a sealing gasket 110 and an elastic element 120.

[0038] One end of the sealing gasket 110 is provided with a mounting groove 111, and one end of the elastic element 120 is engaged with the mounting groove 111.

[0039] The mounting groove 111 has an anti-detachment part 112 that is connected to the elastic member 120.

[0040] Please refer to Figures 1-4 The working principle of the sealing structure 100 is as follows:

[0041] The sealing structure 100 includes a sealing gasket 110 and an elastic member 120. One end of the sealing gasket 110 has a mounting groove 111, and one end of the elastic member 120 engages with the mounting groove 111. Furthermore, the wall of the mounting groove 111 is provided with an anti-detachment part 112 that connects to the elastic member 120. Thus, by configuring the mounting groove 111 at the end of the sealing gasket 110 near the elastic member 120 and configuring the anti-detachment part 112 within the mounting groove 111, the sealing structure 100 can improve the positioning accuracy of the elastic member 120, thereby increasing assembly efficiency and connection stability, and preventing the elastic member 120 from loosening or falling off.

[0042] Moreover, this arrangement allows part of the elastic element 120 to be located within the mounting groove 111 in the sealing gasket 110, and the structure has good stability after assembly. Therefore, it can also reduce the space it occupies, optimize the structural volume, and reduce weight and cost.

[0043] Furthermore, the elastic element 120 can provide stable and continuous pressure to the gasket 110, thereby improving the sealing performance of the gasket 110 installation site.

[0044] It should be noted that in this embodiment, the elastic element 120 is a spring. When one end of the elastic element 120 is engaged with the mounting groove 111, it means that one end of the elastic element 120 can be accommodated in the mounting groove 111, that is, it has a suitable installation size. The end portion of the elastic element 120 accommodated in the mounting groove 111 abuts against or leaves a gap with the inner wall of the mounting groove 111. Moreover, this embodiment is described using a wave spring as an example. In other embodiments, it can also be a spring of other structural types.

[0045] For further details, please refer to Figures 1-4 In this embodiment, when configuring the mounting groove 111, it is set at one end of the sealing gasket 110 near the elastic member 120. The purpose of the mounting groove 111 is to both position the elastic member 120 and fix it to prevent it from loosening or falling off. Based on this, the mounting groove 111 can be opened in various ways. For example, the mounting groove 111 can be set around the axis of the sealing gasket 110 on the inner circumferential surface of the sealing gasket 110 or on the end face of the sealing gasket 110. Moreover, when the mounting groove 111 is set on the end face of the sealing gasket 110, the mounting groove 111 is recessed from the left end face of the sealing gasket 110 toward the right end face. In addition, the mounting groove 111 can also be set on the outer circumferential surface of the sealing gasket 110.

[0046] In this embodiment, the mounting groove 111 is disposed on the inner circumferential surface of the sealing gasket 110, and the mounting groove 111 is an L-shaped groove disposed on the inner circumferential surface of the sealing gasket 110. The purpose of this arrangement is to improve the assembly efficiency and stability of the elastic member 120.

[0047] When configuring the anti-detachment part 112, its function is to limit the displacement of the elastic member 120 located in the mounting groove 111. Based on this, there are various ways to configure it. The anti-detachment part 112 will be configured as a boss 113 (e.g.) Figure 4 and Figure 5 (as shown), tooth 114 (as shown) Figure 6 and Figure 7 (as shown) and limiting groove 115 (as shown) Figure 8 The methods shown will be explained in detail one by one;

[0048] Please refer to Figures 1-5 When the anti-detachment part 112 is set as a boss 113:

[0049] The anti-detachment part 112 includes a plurality of bosses 113 spaced apart around the axis of the sealing gasket 110, each boss 113 being used to engage with the elastic element 120. Taking the elastic element 120 as a wave spring as an example, when the bosses 113 engage with the elastic element 120, the bosses 113 are inserted into the interlayer gaps of the elastic element 120, or a groove that mates with the elastic element 120 can be provided on the bosses 113. Thus, when configuring the bosses 113, the elastic element 120 extending into the mounting groove 111 can be engaged by the bosses 113, thereby limiting its displacement relative to the mounting groove 111, and thus improving the installation stability of the elastic element 120 through this arrangement.

[0050] Furthermore, when configuring the boss 113, to avoid it affecting the fit between the elastic element 120 and the mounting groove 111, that is, to improve the assembly efficiency of the elastic element 120 and the mounting groove 111, the boss 113 can extend along the axial direction of the sealing gasket 110. Moreover, along the axial direction of the sealing gasket 110, from the outside of the sealing gasket 110 to the inside of the sealing gasket 110 (e.g., Figure 4 (In the direction indicated by the middle arrow D), the distance between the surface of the boss 113 away from the inner peripheral wall of the sealing gasket 110 and the axis of the sealing gasket 110 gradually decreases; wherein, the maximum distance between the surface of the boss 113 away from the inner peripheral wall of the sealing gasket 110 and the axis of the sealing gasket 110 is less than the outer diameter of the elastic element 120.

[0051] That is, in this way, the boss 113 gradually increases in size from the end of the sealing gasket 110 toward its interior, thereby guiding the elastic member 120 to extend into the bottom of the mounting groove 111, so as to improve assembly efficiency. Moreover, in order for the boss 113 to engage with the elastic member 120, the maximum distance between the axis of the boss 113 and the sealing gasket 110 is less than the outer diameter of the elastic member 120.

[0052] It should be noted that, when the elastic member 120 is guided to extend into the bottom of the mounting groove 111 and installed in place, in order to improve the installation stability of the elastic member 120, a retaining groove can be configured at the position of the boss 113 corresponding to the end of the elastic member 120. The distance between the surface of the retaining groove away from the inner peripheral wall of the sealing gasket 110 and the axis of the sealing gasket 110 is the same as the outer diameter of the end of the elastic member 120, so that the end of the elastic member 120 can be accommodated. Moreover, in this case, the retaining groove structure at this location forms a variable diameter with the rest of the boss 113, thereby enhancing the locking effect on the elastic member 120.

[0053] Please refer to Figures 1-7 When the anti-detachment part 112 is set as a locking tooth 114:

[0054] The anti-detachment part 112 includes a plurality of locking teeth 114 arranged in a ring array around the axis of the sealing gasket 110 on the groove wall of the mounting groove 111. This arrangement, by having the locking teeth 114 arranged in an array on the inner wall of the mounting groove 111, results in multiple rings of locking teeth 114 distributed along the axis of the sealing gasket 110, with each ring capable of engaging with the elastic member 120. This arrangement allows for the formation of multiple ring structures that provide engagement as the elastic member 120 extends into the mounting groove 111, thereby improving its anti-detachment performance. Furthermore, this arrangement allows for adjustment of the length of the elastic member 120 extending into the mounting groove 111.

[0055] In addition, in order to allow the elastic element 120 to smoothly extend into the mounting groove 111 and engage with the locking teeth 114, the distance between the locking teeth 114 and the axis of the sealing gasket 110 gradually increases from the outside to the inside of the sealing gasket 110, that is, it is set as a wedge structure; wherein, the maximum distance between the axis of each locking tooth 114 and the sealing gasket 110 is less than the outer diameter of the elastic element 120.

[0056] Please refer to Figures 1-8 When the anti-detachment part 112 is set as the limiting groove 115:

[0057] The anti-detachment part 112 includes a limiting groove 115 disposed on the groove wall of the mounting groove 111 around the axis of the sealing gasket 110. The limiting groove 115 is used to engage with one end of the elastic member 120 located in the mounting groove 111. It should be noted that, taking the engagement of the limiting groove 115 with one end of the elastic member 120 extending into the mounting groove 111 as an example, when the limiting groove 115 is provided on the groove wall of the mounting groove 111, the position of the limiting groove 115 can be adaptively set according to the position of the end of the elastic member 120 extending into the mounting groove 111. That is, when the elastic member 120 extends into the bottom of the mounting groove 111, the limiting groove 115 is set at the bottom of the mounting groove 111, that is, along the direction from the outside of the sealing gasket 110 to the inside of the sealing gasket 110 (e.g., ...). Figure 8 (As indicated by the middle arrow D), the limiting groove 115 is located at the end of the mounting groove 111, and the inner diameter of the limiting groove 115 is larger than the inner diameter of the mounting groove 111. In this way, one end of the elastic element 120 located in the mounting groove 111 can be engaged into the limiting groove 115, thereby playing a role in positioning and preventing it from falling off.

[0058] It should be noted that when configuring the aforementioned boss 113, limiting groove 115 and locking tooth 114, one of the aforementioned can be selected as the anti-detachment part 112, or multiple structures can be combined.

[0059] Based on the above, please refer to Figures 1-8This embodiment also provides a valve body device, which includes a valve body, a valve core, and the aforementioned sealing structure 100; the valve body is provided with a flow channel, and the sealing structure 100 is disposed at the flow channel and abuts against the valve core.

[0060] The valve body device employs the aforementioned sealing structure 100, which is installed at the flow port of the valve body and fits tightly with the valve body and valve core. Through the interaction of the sealing gasket and the elastic element, the sealing performance between the flow port of the valve body and the valve core is ensured. Specifically, the installation groove 111 and the anti-detachment part 112 improve the positioning accuracy of the elastic element 120, thereby improving assembly efficiency, enhancing the stability of its connection, and preventing the elastic element 120 from loosening or falling off. Furthermore, based on the improved installation stability of the elastic element 120, it can provide the sealing gasket 110 with continuous temperature installation pressure, thus effectively maintaining the installation state of the sealing gasket 110 and improving the sealing performance at the installation point of the sealing gasket 110 in the valve body device.

[0061] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
