[0017] 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.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] This utility model provides the following technical solution:

[0020] As attached Figures 1-3As shown, this utility model discloses a sealing pipe fitting connector, including a pipe fitting body 1, a pipe fitting channel 2 formed within the pipe fitting body 1, a body portion 3, and connector portions 4 disposed at both ends of the body portion 3. At least two connector limiting portions 10 protrude from the inner wall of the body portion 3, dividing the pipe fitting channel 2 into a left channel 11 and a right channel 12. External connectors (not shown) extend into both ends of the pipe fitting channel 2, and the external connectors abut against both sides of the connector limiting portions 10. Specifically, in this embodiment, the connector limiting portions 10 not only separate the pipe fitting channel 2 but also precisely define the installation position of the external connectors. When the external connectors are connected to the pipe fitting body 1, they abut against both sides of the connector limiting portions 10, ensuring the stability and firmness of the connector. Simultaneously, the independent separation of the left channel 11 and the right channel 12 makes the fluid flow inside the pipe fitting more orderly, reducing mutual interference between fluids and improving the working efficiency of the pipe fitting. In addition, the protruding structure of the connector limiting part 10 increases the structural strength of the pipe body 1, enabling it to maintain better stability and durability when facing high pressure or high flow rate fluids.

[0021] Furthermore, a sealing ring placement part 5 is formed between the main body part 3 and the connector part 4. A sealing ring groove 6 is formed inside the pipe body 1 corresponding to the sealing ring placement part 5. The sealing ring groove 6 has a sealing ring positioning part 7 and a sealing ring deformation positioning part 8. A sealing ring 9 is disposed within the sealing ring positioning part 7, and the portion of the sealing ring 9 that deforms under force extends into the sealing ring deformation positioning part 8. Specifically, in this design, the sealing ring placement part 5 provided between the pipe body 1 and the connector part 4 provides a stable installation environment for the sealing ring, ensuring accurate positioning during pipe connection. The cooperation between the sealing ring positioning part 7 and the sealing ring deformation positioning part 8 in the sealing ring groove 6 allows the sealing ring to maintain stable positioning after installation and to undergo moderate deformation under external force, thus tightly fitting the inner wall of the pipe body 1, effectively improving sealing performance, enhancing the durability and reliability of the pipe, and maintaining good sealing performance under various complex working conditions.

[0022] Furthermore, the axial cross-sectional shape of the connector limiting part 10 is arc-shaped, and the outer wall of the main body is concave to form an arc-shaped groove 14 corresponding to the shape of the connector limiting part 10. Specifically, in this embodiment, the connector limiting part 10 is hemispherical, which allows the axial movement of the external connector to be effectively restricted by the tight fit between the hemispherical connector limiting part 10 and the arc-shaped groove 14 when the external connector abuts against the connector limiting part 10, further enhancing the stability of the pipe connection. In addition, this arc-shaped connector limiting part 10 design can also absorb and disperse the impact force at the connection to a certain extent, improving the seismic performance of the entire pipe system.

[0023] Furthermore, the axial cross-sectional shape of the connector limiting part is trapezoidal, and a trapezoidal groove 15 corresponding to the shape of the connector limiting part is formed on the outer wall of the main body. Specifically, in this embodiment, the connector limiting part 10 is trapezoidal, which allows the radial movement of the external connector to be effectively restricted through the tight fit between the trapezoidal connector limiting part 10 and the trapezoidal groove 15 when the external connector abuts against the connector limiting part 10, further improving the stability and sealing effect of the pipe connection. This trapezoidal connector limiting part 10 design can also disperse the pressure to the pipe body through the trapezoidal inclined surface when the pipe is subjected to lateral pressure, enhancing the overall load-bearing capacity of the pipe. In addition, the fit between the trapezoidal connector limiting part 10 and the trapezoidal groove 15 also facilitates precise positioning of the external connector during installation, improving installation efficiency and accuracy.

[0024] Furthermore, a symmetrical rounded corner structure 13 is provided between the sealing ring placement part 5, the connector part 4, and the body part 3. Specifically, in this embodiment, the rounded corner structure 13 is designed to optimize the installation process of the sealing ring and enhance the overall sealing performance of the pipe fitting. By adopting a symmetrical rounded corner design, it is not only easier to smoothly insert the sealing ring during installation and reduce installation resistance, but also effectively prevents the sealing ring from being damaged by sharp edges during installation, thereby extending the service life of the sealing ring. In addition, the rounded corner structure 13 can also disperse stress concentration at the pipe fitting connection to a certain extent, enhance the structural stability of the pipe fitting, ensure the sealing effect of the pipe fitting under high pressure or harsh working environments, and further improve the safety and reliability of the pipe fitting. The radius of the rounded corner structure 13 is carefully calculated to ensure that it meets the installation requirements and achieves the best sealing effect.

[0025] Furthermore, the sealing ring deformation positioning part 8 extends from both sides of the sealing ring positioning part 7 toward the inner wall of the connector part 4 and the inner wall of the body part 3. Specifically, in this embodiment, the sealing ring deformation positioning part is designed to better fix and support the sealing ring, preventing it from shifting or deforming during operation. By extending from both sides of the sealing ring positioning part 7 toward the inner wall of the connector part 4 and the inner wall of the body part 3, this deformation positioning part can provide a stable support surface, ensuring that the sealing ring can maintain its correct position after installation, and maintain its sealing performance even under the action of high pressure or high flow rate fluids. This design not only enhances the stability of the sealing ring, but also improves the sealing effect and durability of the entire pipe system.

[0026] Furthermore, the inner wall of the deformation positioning part 8 of the sealing ring is arranged in an arc shape. Specifically, in this embodiment, this arc-shaped inner wall structure design aims to further optimize the stress situation of the sealing ring. By adopting an arc structure, the deformation positioning part can better fit the curved surface of the sealing ring, reducing stress concentration caused by shape mismatch. This not only helps to improve the stability and durability of the sealing ring, but also ensures that it maintains a good sealing effect during long-term operation. At the same time, the arc-shaped inner wall structure is also more conducive to the smooth flow of fluid, reducing fluid resistance and improving the overall performance of the piping system.

[0027] Furthermore, in another embodiment, the inner wall of the arc-shaped deformation positioning part 8 of the sealing ring is configured with a slope structure. Specifically, in this embodiment, this sloped inner wall design is intended to further improve the adaptability and stability of the sealing ring 9 during installation and under stress. The sloped structure design makes it easier for the deformation positioning part to guide the sealing ring 9 into the correct position during installation, reducing installation difficulty and errors. At the same time, under fluid pressure, the sloped structure can better disperse stress, avoiding stress concentration in a local area, thereby extending the service life of the sealing ring. In addition, the sloped structure also helps to improve the fit between the sealing ring and the deformation positioning part, further enhancing the sealing effect and ensuring that the piping system maintains good sealing performance under various operating conditions.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
