Description

Technical Field

[0001] The utility model relates to a reservoir construction pipeline interface docking structure, belonging to the technical field of water conservancy pipeline construction. Background Art

[0002] When constructing water conservancy facilities such as reservoirs, pipelines are laid to guide and discharge water and other fluids. After the pipeline segments are transported to the construction site, the pipe joints need to be connected to ensure the extension and laying. When the pipe joints are connected, sealing rings are installed to ensure a tight seal.

[0003] The prior art is shown in Chinese patent publication number CN2058716U, which discloses a technology in which a rubber sealing ring is installed at the stepped bottom of the cast iron pipe socket to be installed with the socket. Although the sealing ring can be installed at the stepped bottom of the pipe interface end for docking, the problem of displacement and detachment easily occurs when the pipe interface is retracted and adjusted. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a reservoir construction pipeline interface docking structure.

[0005] The utility model is achieved through the following technical solutions.

[0006] The utility model provides a reservoir construction pipeline interface docking structure, comprising:

[0007] The radial outer protrusion of the pipeline A is provided with a protruding ring for the elastic sealing ring.

[0008] It also includes a pipe B which is sleeved on the outside of the pipe A, and the inner diameter surface of the pipe B is in close contact with the elastic sealing ring.

[0009] The end surface of the pipe B is provided with a pin for limiting the end of the elastic sealing ring away from the convex ring.

[0010] An oblique hole is provided on the end surface of the pipe B that is close to the pipe A, and a pin is inserted into the oblique hole. The elastic sealing ring has a limiting notch, and the pin in an inclined state is inserted into the limiting notch.

[0011] The oblique hole at the end of the pin is provided with a blocking layer.

[0012] The end of the pipe B is covered with a tension ring, which is screwed with a tightening ring through bolts and nuts, and the tightening ring presses the elastic sealing ring axially.

[0013] The beneficial effect of the present invention is that: pipe B is sleeved on the outside of pipe A and is in close contact with the elastic sealing ring. When pipe B is retracted away from pipe A, the elastic sealing ring is limited by the convex ring and is not easily displaced or detached, which solves the problem that the sealing ring is installed at the sunken step at the end of the pipe interface and is easily displaced or detached when the pipe interface is retracted or adjusted.

[0018] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0019] like Figures 1 to 3 shown.

[0020] The present invention provides a reservoir pipeline interface construction method, comprising the following steps:

[0021] Docking installation steps: an elastic sealing ring 2 made of elastic rubber is installed at the convex ring 11 at the end of pipe A1, and the elastic sealing ring 2 is limited by the radially protruding convex ring 11; pipe B3 is put on the outside of pipe A1; the tension ring 4 is put on the end of pipe B3, and the tension ring 4 is screwed with a tightening ring 5 through a bolt 41 and a nut 42, and the tightening ring 5 presses the elastic sealing ring 2 axially; screw the nut 42 to pull pipe B3 to dock with pipe A1. During this process, tighten the nut 42 to the right so that the tightening ring 5 presses the elastic sealing ring 2, and the elastic sealing ring 2 is squeezed to the inner diameter surface of pipe B3 along the inclined convex ring 11, so that the inner diameter surface of pipe B3 is in close contact with the elastic sealing ring 2 for sealing.

[0022] Pin limiting step: insert the pin 6 into the inclined hole at the end of the pipe B3, and insert the inclined pin 6 into the limiting notch 21 of the elastic sealing ring 2. The pin 6 limits the elastic sealing ring 2 from retreating. The axial elastic force generated by the retreat of the elastic sealing ring 2 is transmitted to the pipe B3 through the inclined pin 6. Fill the oblique hole at the end of the pipe B3 with a blocking layer 7 to block the end of the pin 6. Figure 2 As shown, the blocking layer 7 can be concrete or glue; the pin 6 is made of ceramic material or zinc-copper alloy material to ensure that the blocking layer 7 and the pin 6 are not easy to oxidize, rust and age; then loosen the nut 42 to the left, remove the bolt 41 and the tension ring 4. At this time, it presents the reservoir construction pipeline interface docking structure, such as Figure 3 As stated.

[0023] The present application relates to a reservoir construction pipeline interface docking structure, comprising:

[0024] A pipe A1 has a convex ring 11 at its end, the convex ring 11 protruding radially outward from the pipe A1; an elastic sealing ring 2 is sleeved on the convex ring 11;

[0025] The pipe B3 is sleeved on the outside of the pipe A1, and the inner diameter surface of the pipe B3 is in close contact with the elastic sealing ring 2.

[0026] The end surface of the pipe B3 close to the pipe A1 is provided with an inclined hole, into which a pin 6 is inserted. The elastic sealing ring 2 has a limiting notch 21, into which the inclined pin 6 is inserted. A blocking layer 7 is provided in the inclined hole at the end of the pin 6.

[0027] Pipe B3 is sleeved on the outside of pipe A1 and is in close contact with the elastic sealing ring 2. When pipe B3 moves away from pipe A1 and retracts, the elastic sealing ring 2 is limited by the convex ring 11 and is not easily displaced or detached, thereby solving the problem that the sealing ring is installed at the sunken step at the end of the pipe interface and is easily displaced or detached when the pipe interface retracts or adjusts.
