Problems solved by technology

[0002] At present, the connection and closure of concrete pipe fittings and steel pipes are mostly connected by welding or flange connection. The pipe fittings of these two kinds of connections need to determine the length of the fittings according to the engineering conditions before they can be customized. However, it is difficult to determine the exact fitting length in engineering applications. Therefore, During the construction process, accessories often undergo on-site cutting or welding and lengthening. The construction site needs to be equipped with generator sets and flame gas cutting equipment, which is time-consuming and labor-intensive. At the same time, it brings inconvenience to the construction of the project, and the welding of the steel plate will cause deformation of the pipe. As a result, it is easy to cause water leakage at the pipe interface, and it is difficult to guarantee the quality of the project.

[0041] See figure 1 The engineering pipeline sliding connection closure provided by this embodiment includes a pipe body 101, which includes an outer pipe 102, an inner pipe 103 and a sealant for sealing the connection between the outer pipe 102 and the inner pipe 103 that are slidably connected to each other Ring 104, the inner tube 103 can slide axially in the outer tube 102.

[0042] A fixing ring 105 is provided on the outer wall of one end of the outer tube 102 close to the inner tube 103, and the fixing ring 105 is fixedly connected to the outer tube 102. A sliding ring 106 is sleeved on the outer side of the inner tube 103, and the sliding ring 106 is slidingly connected to the inner tube 103. The fixing ring 105 and the sliding ring 106 are correspondingly provided with a number of threaded holes, and the fixing ring 105 and the sliding ring 106 are connected by a high-strength bolt 107.

[0043] When the high-strength bolt 107 is tightened, the sliding ring 106 and the fix...

[0048] See figure 2 The engineering pipeline sliding connection closure provided by this embodiment has the same basic structure, principle and technical effect as the first embodiment. For a brief description, for parts not mentioned in this embodiment, please refer to the first embodiment The corresponding content in the example.

[0049] See figure 2 with image 3 A side of the sliding ring 106 close to the sealing rubber ring 104 is provided with an inclined surface 112 for pressing the sealing rubber ring 104 against the outer wall of the inner tube 103.

[0050] When the high-strength bolt 107 is tightened, the inclined surface 112 on the sliding ring 106 exerts an oblique force on the sealing rubber ring 104. Under the action of the oblique force, the sealing rubber ring 104 can better interact with the outer wall of the inner tube 103, The end surface of the outer tube 102 close to the sliding ring 106 is closely attached to effectively avoid the radial gap between the se...

[0069] See Figure 5 The difference between the engineering pipeline sliding connection closure provided in this embodiment and the engineering pipeline sliding connection closure provided in the second embodiment is that: in this embodiment, there are two inner tubes 103 and one outer tube 102.

[0070] See Figure 5 Specifically, the inner tube 103 includes a first inner tube 113 and a second inner tube 114, the socket ring 109 is arranged at one end of the first inner tube 113 away from the outer tube 102, and the socket ring 110 is arranged at the second inner tube 114 away from One end of the outer tube 102.

[0071] Both ends of the outer tube 102 are respectively provided with a first fixing ring 115 and a second fixing ring 116, the first inner tube 113 is sheathed with a first sliding ring 117, and the second inner tube 114 is sheathed with a second sliding ring 118. A fixed ring 115 and the first sliding ring 117 are connected by a first high-strength bolt 119, and the se...
