Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-2 This embodiment provides the following technical solution: a valve body connector, including a connector body 10, wherein a through flow channel 20 is provided inside the connector body 10; the connector body 10 is provided with a plurality of sealing grooves 30 for installing sealing rings 30 to achieve sealing, and the plurality of sealing grooves are evenly distributed along the axial direction of the connector body 10; the connector body 10 is provided with a plurality of clamp grooves 40 for assembling the connector body 10 with clamp bodies, and the plurality of clamp grooves 40 and the plurality of sealing grooves 30 are staggered; through the provision of the plurality of sealing grooves 30 and clamp grooves 40, leakage is effectively avoided, ensuring the sealing performance of the medium transmission in the valve body system, and enhancing the connection stability, preventing the connector body 10 from loosening, and improving the overall structural reliability.

[0026] In some embodiments, the connector body 10 is made of stainless steel and the surface is treated with anti-corrosion measures, such as chrome plating or spraying an anti-corrosion coating, to improve corrosion resistance and adapt to complex working environments.

[0027] The connector body 10 includes an input connection part 11, an output connection part 12, and an intermediate connection part 13. The input connection part 11, the output connection part 12, and the intermediate connection part 13 are coaxially arranged, and the input connection part 11 and the output connection part 12 are fixedly connected through the intermediate connection part 13.

[0028] In some embodiments, the outer diameter of the intermediate connecting portion 13 is larger than the outer diameters of the input connecting portion 11 and the output connecting portion 12, wherein the outer diameter of the input connecting portion 11 is larger than the outer diameter of the output connecting portion 12.

[0029] Three sealing grooves 30 are provided: the sealing groove 30 on the input connection part 11 is the first sealing groove 31, the sealing groove 30 on the intermediate connection part 13 is the second sealing groove 32, and the sealing groove 30 on the output connection part 12 is the third sealing groove 33. Through the provision of the first sealing groove 31, the second sealing groove 32, and the third sealing groove 33, in actual use, when the connector body is connected to the connected valve body, the externally applied pressure will cause the sealing ring to undergo elastic deformation. The rubber sealing ring has good elasticity, and it will fill the gap between the sealing groove 30 and the connected component such as the valve body interface, thereby preventing the medium such as gas or liquid from leaking from the connector.

[0030] Two clamp slots 40 are provided, which are located on the middle connecting part 13 and on both sides of the second sealing groove 32. The clamp slot 40 between the second sealing groove 32 and the first sealing groove 31 is the first clamp slot 41, and the clamp slot 40 between the second sealing groove 32 and the third sealing groove 33 is the second clamp slot 42. With the first clamp slot 41 and the second clamp slot 42, when the clamp is installed in the first clamp slot 41 and the second clamp slot 42, the clamp generates a clamping force on the valve body connector and the connected valve body by external force such as using a tool to clamp it, thereby limiting the relative displacement between the two and ensuring the connection stability between the connector body 10 and the valve body.

[0031] In some embodiments, the outer diameter of the first clamp groove 41 is larger than the outer diameter of the second clamp groove 42.

[0032] Example 2

[0033] Please see Figure 3-4 Since the medium enters the body 10 of the connector and first impacts the sealing surface of the input connection 11, in order to improve its sealing performance, the first sealing groove 31 includes a main sealing section 311 and an auxiliary sealing section 312. The main sealing section 311 and the auxiliary sealing section 312 are distributed sequentially along the flow direction of the medium in the flow channel 20. An elastic self-adaptive sealing ring is provided in the main sealing section 311, and an expansion sealing block is provided in the auxiliary sealing section 312.

[0034] In some embodiments, the elastic adaptive sealing ring uses a nickel-titanium shape memory alloy as the inner skeleton and is wrapped with fluororubber on the outer layer. It is composite molded by co-vulcanization process, so that the sealing ring can adaptively adjust its shape with changes in temperature and pressure.

[0035] The auxiliary sealing section 312 is embedded with a sealing block made of highly absorbent and expandable rubber that expands when in contact with media. The size of the block matches that of the auxiliary sealing section 312, and it expands to fill tiny gaps after contact with media such as water and oil.

[0036] The main sealing section 311 and the auxiliary sealing section 312 are coaxially distributed in a stepped manner, and the groove depth and groove width of the main sealing section 311 are greater than those of the auxiliary sealing section 312. The main sealing section 311 and the auxiliary sealing section 312 together form a stepped spatial layout, constructing a double sealing barrier.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
