Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a connecting seat. Background Technology

[0002] The exhaust valve is usually installed at a high point on the main pipeline. In order to facilitate the connection between the exhaust valve and the main pipeline, the existing technology usually uses a connecting seat to connect the exhaust valve and the main pipeline. That is, one end of the connecting seat is connected to the exhaust valve and the other end of the connecting seat is connected to the main pipeline.

[0003] Existing connectors are typically two-part structures, consisting of an upper first connector and a lower second connector. The second connector includes an external threaded section and a sealing ring, with the sealing ring located above the external threaded section.

[0004] The main pipeline is equipped with an internal thread section and a receiving groove, which is located at the port of the main pipeline. In actual installation, in order to achieve the ideal sealing effect, the receiving groove needs to be temporarily processed according to the wire diameter (size) of the sealing ring, resulting in a cumbersome installation process and low assembly efficiency. Utility Model Content

[0005] This utility model provides a connector, the purpose of which is to overcome the problem of low installation efficiency in the prior art.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A connector includes a first connector and a second connector, which are fixed to each other and communicate with each other. The outer wall of the second connector is provided with an external thread section, and a sealing ring for sealing fit is provided in the interval where the external thread section is located.

[0008] In the recommended embodiment, the sealing ring protrudes radially from the external threaded section, improving the sealing effect.

[0009] In the recommended embodiment, an annular groove is provided within the section containing the external thread segment, and the sealing ring is fitted into this groove. The sealing ring is installed within the groove to ensure it will not fall off.

[0010] In the recommended embodiment, the width of the groove is greater than the width of the sealing ring, which facilitates the installation of the sealing ring.

[0011] In the recommended embodiment, the groove has a bottom surface with knurled grooves evenly distributed thereon. The knurled grooves provide redundancy for the deformation of the sealing ring and also prevent rotation of the sealing ring.

[0012] In the recommended embodiment, the knurling groove extends along the width direction of the groove, which facilitates the processing of the knurling groove.

[0013] In the recommended embodiment, the groove includes a bottom surface and inclined side surfaces located on both sides of the bottom surface. The inclined side surfaces facilitate the installation of the sealing ring.

[0014] In the recommended implementation, the inclination angle of the inclined side is an obtuse angle.

[0015] In the recommended embodiment, the sealing ring is made of PTFE, which has a certain degree of wear resistance, ensuring that the connector still has good sealing performance after repeated disassembly and assembly.

[0016] In the recommended implementation, the outer wall of the first connector is formed with a wrench structure for easy assembly and disassembly.

[0017] The beneficial effects of this utility model are:

[0018] This invention directly sets a sealing ring in the section where the external thread of the second connector is located. During installation, it can directly seal with the internal thread interface of the main pipeline (without needing to open a receiving groove in the internal thread interface of the main pipeline), thus significantly improving installation efficiency.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] Reference Figure 1 and Figure 4 A connector includes a first connector 2 for connecting to an exhaust valve 1 and a second connector 4 for connecting to a main pipeline 3, wherein the first connector 2 and the second connector 4 are fixed to each other and communicate with each other.

[0029] Simultaneously refer to Figure 2 To facilitate assembly and disassembly, the outer wall of the first connector 2 forms a wrench structure 21. This wrench structure 21 has several force-bearing surfaces for use with tools such as wrenches. In this embodiment, the cross-section of the wrench structure 21 is polygonal. Of course, the wrench structure 21 in this application is not limited to polygonal shapes; it can also be designed into other shapes according to actual needs. (See also...) Figure 3 The inner wall of the first connector 2 is provided with an internal thread structure 22, which is used to connect with the inlet / outlet connector 11 at the lower end of the exhaust valve 1.

[0030] Reference Figure 1The outer wall of the second connector 4 is provided with an external thread section 41, and a sealing ring 42 for sealing and engaging with the main pipeline 3 is provided within the section of the external thread section 41. The sealing ring 42 of this application is located in the middle of the external thread section 41, but it can also be offset upwards or downwards from the middle position as needed.

[0031] Simultaneously refer to Figure 3 In this embodiment, the external thread section 41 has an annular groove 40 in the middle, and the sealing ring 42 is fixedly fitted inside the groove 40. To facilitate the installation of the sealing ring 42, the width of the groove 40 is slightly larger than the width of the sealing ring 42.

[0032] As can be seen from the figure, the groove 40 includes a bottom surface 401 and inclined side surfaces 402 located on both sides of the bottom surface 401. In order to facilitate the installation of the sealing ring, the inclined side surface 402 has an obtuse angle.

[0033] Simultaneously refer to Figure 2 The bottom surface 401 of the groove 40 is evenly provided with knurled grooves 403. The knurled grooves 403 provide redundant space for deformation of the sealing ring 42 and prevent the sealing ring 42 from rotating. In addition, to facilitate the processing of the knurled grooves 403, the knurled grooves 403 extend along the width direction of the groove 40.

[0034] Continue to refer to Figure 1 To ensure a good sealing effect, the sealing ring 42 protrudes slightly from the external thread section 41 in the radial direction. Furthermore, the sealing ring 42 in this embodiment is made of PTFE (polytetrafluoroethylene), which has a certain degree of wear resistance, ensuring that the connector 100 maintains good sealing performance even after repeated disassembly and assembly. In addition, the material of the sealing ring 42 is not limited to PTFE; it can also be other materials, as long as they have a certain degree of hardness and wear resistance.

[0035] Reference Figure 4 The specific installation process in this embodiment is as follows:

[0036] First, the second connector 4 of the connector 100 is directly threaded onto the internal thread interface 31 of the main pipeline 3. Then, the exhaust valve 1 is threaded onto the first connector 2 of the connector 100. This invention directly sets a sealing ring 42 within the area where the external thread section 41 of the second connector 4 is located. During installation, it can directly seal with the internal thread interface 31 of the main pipeline 3 (without needing to create a receiving groove on the internal thread interface of the main pipeline), thus significantly improving installation efficiency.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
