Description

Technical Field

[0001] This utility model relates to the field of water pipe elbow technology, and in particular to a special-shaped socket water pipe elbow. Background Technology

[0002] A socket-and-socket water pipe elbow consists of a spigot, a socket, and a bend. The key design element is the socket-and-socket structure at the spigot end. This design achieves connection by inserting the pipe into the socket, eliminating the need for complex welding or threading, significantly reducing installation difficulty. Its sealing performance relies on the tight fit of the socket joint; combining it with rubber gaskets or sealant can further improve leak-proof performance. Patent application number 202421020051.6 discloses a non-standard socket-and-socket water pipe elbow, including a non-standard socket-and-socket elbow, an elliptical large pipe, and an elliptical small pipe. The non-standard socket-and-socket elbow includes a water pipe elbow, an upper flat section, a lower flat section, a limiting ring, a first rubber ring, and a second rubber ring. In this patent, the first and second rubber rings are used to limit the elliptical large and small pipes. However, due to the lack of limiting, the rubber rings are prone to displacement during use and insertion / removal, affecting both connection stability and sealing performance. Therefore, we present a non-standard socket-and-socket water pipe elbow. Utility Model Content

[0003] The main purpose of this utility model is to provide a special-shaped socket water pipe elbow, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A special-shaped socket water pipe elbow includes an elbow body, a small pipe inserted and connected to the right end of the elbow body, a large pipe inserted and connected to the lower end of the elbow body, a reinforcing mechanism fixedly connected to the outer surface of the elbow body, a groove opened at the right end of the elbow body, two No. 1 sealing devices fixedly connected to the inner wall of the groove, and two No. 2 sealing devices fixedly connected to the lower part of the outer surface of the elbow body.

[0006] Preferably, the second sealing device includes a fourth limiting ring and a fifth limiting ring. The fourth limiting ring has a structure that is narrower at the top and wider at the bottom, and the fifth limiting ring has a structure that is narrower at the bottom and wider at the top. The second sealing ring is interlocked between the fourth limiting ring and the second sealing ring.

[0007] Preferably, the fourth and fifth limiting rings are fixedly connected to the outer surface of the elbow body, and the second sealing ring is sleeved on the outer surface of the elbow body.

[0008] Preferably, the first sealing device includes a second limiting ring and a third limiting ring, with a first sealing ring inserted between the third limiting ring and the second limiting ring.

[0009] Preferably, the second and third limiting rings are fixedly connected to the inner wall of the groove, the first sealing ring is not connected to the inner wall of the groove, and the first sealing ring is in contact with the outer surface of the tube.

[0010] Preferably, the reinforcement mechanism includes a connecting ring, and a reinforcement rod is fixedly connected to both the front and rear left ends of the connecting ring. A reinforcing rod is fixedly connected to the ends of the two reinforcement rods that are close to each other, and a first limiting ring is fixedly connected to the ends of the two reinforcement rods that are away from the connecting ring.

[0011] Preferably, both reinforcing rods are inclined, and the connecting ring and the first limiting ring are fixedly connected to the outer surface of the elbow body.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, two No. 2 sealing devices are set on the outer surface of the elbow body. The No. 2 sealing device consists of a No. 4 limiting ring, a No. 2 sealing ring, and a No. 5 limiting ring. The No. 2 sealing ring is located between the No. 4 limiting ring and the No. 5 limiting ring, thereby limiting the No. 2 sealing ring. When the large pipe is inserted into the lower end of the elbow body, the No. 2 sealing ring contacts the inner wall of the elbow body and cannot move up and down, thereby improving stability and avoiding misalignment. Two No. 1 sealing devices are set on the inner wall of the elbow body. The No. 1 sealing device consists of a No. 2 limiting ring, a No. 1 sealing ring, and a No. 3 limiting ring. When the small pipe is inserted into the right end of the elbow body, the small pipe is located inside the No. 1 sealing ring. The No. 1 sealing ring cannot move under the clamping action of the No. 2 limiting ring and the No. 3 limiting ring, so that the No. 1 sealing ring is tightly fitted on the outer surface of the small pipe, thereby avoiding misalignment and improving tightness.

[0014] 2. In this utility model, by setting a reinforcement mechanism, the first limiting ring and the connecting ring are respectively fixed to the lower part of the outer surface of the elbow body and the right part of the outer surface, and two reinforcement rods are connected between them. Under the action of the two reinforcement rods, the bending part of the elbow body can be supported, thereby preventing the bending part of the elbow body from breaking and deforming.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A special-shaped socket water pipe elbow includes an elbow body 1, a small pipe 3 inserted and connected to the right end of the elbow body 1, a large pipe 4 inserted and connected to the lower end of the elbow body 1, a reinforcing mechanism 2 fixedly connected to the outer surface of the elbow body 1, a groove 5 opened at the right end of the elbow body 1, two No. 1 sealing devices 6 fixedly connected to the inner wall of the groove 5, and two No. 2 sealing devices 7 fixedly connected to the lower part of the outer surface of the elbow body 1.

[0026] In this embodiment, the second sealing device 7 includes a fourth limiting ring 71 and a fifth limiting ring 73. The fourth limiting ring 71 has a structure that is narrower at the top and wider at the bottom, while the fifth limiting ring 73 has a structure that is narrower at the bottom and wider at the top. The second sealing ring 72 is inserted between the fourth limiting ring 71 and the second sealing ring 72. Both the fourth limiting ring 71 and the fifth limiting ring 73 are fixedly connected to the outer surface of the elbow body 1, and the second sealing ring 72 is sleeved on the outer surface of the elbow body 1. The first sealing device 6 includes a second limiting ring 61 and a third limiting ring 63. The first sealing ring 62 is inserted between the third limiting ring 63 and the second limiting ring 61. Both the second limiting ring 61 and the third limiting ring 63 are fixedly connected to the inner wall of the groove 5, while the first sealing ring 62 is not connected to the inner wall of the groove 5 and is in contact with the outer surface of the small tube 3.

[0027] Through the above scheme: when the large pipe 4 is smoothly inserted into the lower end of the elbow body 1, the second sealing ring 72, due to its flexibility and elasticity, will be in close contact with the inner wall of the elbow body 1. At this time, due to the double restriction of the fourth limiting ring 71 and the fifth limiting ring 73, the second sealing ring 72 is firmly fixed in the predetermined position and cannot move up or down. When the small pipe 3 is inserted into the right end of the elbow body 1, the small pipe 3 will be precisely located inside the first sealing ring 62. Under the tight clamping action of the second limiting ring 61 and the third limiting ring 63, the first sealing ring 62 is firmly fixed and cannot be displaced.

[0028] In this embodiment, the reinforcement mechanism 2 includes a connecting ring 21. Reinforcing rods 22 are fixedly connected to the front and rear left ends of the connecting ring 21. A reinforcing rod 23 is fixedly connected to the ends of the two reinforcing rods 22 that are close to each other. A first limiting ring 24 is fixedly connected to the ends of the two reinforcing rods 22 that are away from the connecting ring 21. Both reinforcing rods 22 are inclined. The connecting ring 21 and the first limiting ring 24 are both inserted and fixedly connected to the outer surface of the elbow body 1.

[0029] With the above scheme, the first limiting ring 24 and the connecting ring 21 are firmly fixed to the lower part of the outer surface and the right part of the outer surface of the elbow body 1, respectively. The two are connected by two reinforcing rods 22, forming a stable support structure at the bend of the elbow body 1, thereby greatly enhancing the load-bearing capacity at the bend of the elbow body 1.

[0030] It should be noted that this utility model describes a special-shaped socket water pipe elbow. Two second-level sealing devices 7 are provided on the outer surface of the elbow body 1. Each second-level sealing device 7 is composed of a fourth-level limiting ring 71, a second-level sealing ring 72, and a fifth-level limiting ring 73. The second-level sealing ring 72 is precisely positioned between the fourth-level limiting ring 71 and the fifth-level limiting ring 73 to prevent unnecessary displacement during operation. When the large pipe 4 is smoothly inserted into the lower end of the elbow body 1, the second-level sealing ring 72, due to its flexibility and elasticity, will tightly seal against the elbow. When the elbow body 1 contacts the inner wall, the second sealing ring 72 is firmly fixed in the predetermined position due to the double restriction of the fourth limiting ring 71 and the fifth limiting ring 73, and cannot move up or down. This stable sealing state greatly improves the sealing performance at the connection between the main pipe 4 and the elbow body 1, effectively avoiding fluid leakage caused by poor sealing, and also avoiding safety hazards such as loose pipe connection caused by misalignment of the sealing ring. On the inner wall of the elbow body 1, two first sealing devices 6 are also set, each of which consists of two... The system consists of a first limiting ring 61, a first sealing ring 62, and a third limiting ring 63. When the small pipe 3 is inserted into the right end of the elbow body 1, the small pipe 3 will be precisely positioned inside the first sealing ring 62. Under the tight clamping action of the second limiting ring 61 and the third limiting ring 63, the first sealing ring 62 is firmly fixed and cannot be displaced. This not only effectively prevents fluid leakage that may occur at the connection between the small pipe 3 and the elbow body 1, but also avoids misalignment caused by pipe shaking or pressure changes through a tight fit, further improving the tightness and stability of the connection. To ensure the normal operation of the pipeline system under various working conditions, and to further enhance the overall structural strength of the elbow body 1, the first limiting ring 24 and the connecting ring 21 are firmly fixed to the lower part of the outer surface and the right part of the outer surface of the elbow body 1, respectively. The two are connected by two reinforcing rods 22, forming a stable support structure at the bend of the elbow body 1. This greatly enhances the load-bearing capacity at the bend of the elbow body 1, avoids problems such as fracture and deformation caused by excessive stress, and ensures the structural integrity and stability of the elbow body 1 during long-term use.
