Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a gap blocking structure. Background Art

[0002] The Haff joint is a sealing joint, a connection tool between pipes, and a detachable connection point between components and pipes. The Haff joint plays an indispensable and important role in pipe fittings. It is one of the two main components of hydraulic pipes. It is usually used for linear connections such as instruments. The connection forms include socket welding or threaded connection. Furthermore, the Haff joint is mainly used for small-diameter low-pressure pipelines, for parts that need to be frequently installed and disassembled, or for the final adjustment of pipelines using threaded pipe fittings. The structural form should adopt a metal surface contact sealing structure. The gasket sealing structure is usually used in general pipelines for conveying water, oil, air, etc., and is made of malleable cast iron. For example, the drainage pipe of the 2×1000MW power plant uses a φ4000*32mm steel pipe. After being sunk in sections, the interfaces between the sections are connected with Haff joints to stop water.

[0003] However, the water-stop rubber (sealing ring gasket) in the Hough joint is easily aged and broken under the long-term erosion of high-temperature water in the drainage pipe, causing large gaps in the pipe at the Hough joint and water leakage.

[0004] Therefore, it is urgent to propose a gap blocking structure to solve the above problems. Utility Model Content

[0005] The utility model provides a gap blocking structure to solve the leakage problem caused by aging and fracture of a sealing ring gasket of a half joint.

[0031] The utility model provides a gap blocking structure to solve the leakage problem caused by aging and fracture of the sealing ring gasket of the half joint 3.

[0032] Specific as Figure 1 and Figure 2 As shown, the gap blocking structure is used to block the broken sealing ring gasket of the half joint 3, and includes a first blocking block 100, a second blocking block 200 and a connecting assembly 300. The first blocking block 100 can be inserted and blocked in the first gap formed by the outer wall of the first pipe 1 and the inner wall of the half joint 3. The first blocking block 100 and the second blocking block 200 are arranged between the first pipe 1 and the second pipe 2 along the first direction; the second blocking block 200 can be inserted and blocked in the second gap formed by the outer wall of the second pipe 2 and the inner wall of the half joint 3, and the two ends of the connecting assembly 300 are connected to the first blocking block 100 and the second blocking block 200 respectively. The first blocking block 100 blocks the first gap and the second blocking block 200 blocks the second gap to solve the leakage problem caused by the aging and breaking of the sealing ring gasket of the half joint 3. And the first blocking block 100 and the second blocking block 200 are connected by the connecting assembly 300, which is convenient to connect and has a simple structure.

[0033] It should be noted that the first direction is the axial direction of the first pipeline 1 and the second pipeline 2 .

[0034] Furthermore, in order to facilitate the insertion of the first blocking block 100, the first blocking block 100 is a first wedge-shaped block, and the wedge-shaped end of the first wedge-shaped block is inserted into the first gap. And the wedge-shaped end can increase the contact area with the first pipe 1 and the half joint 3, thereby increasing the sealing performance of the connection between the first pipe 1 and the half joint 3, and further solving the leakage problem.

[0035] Similarly, in order to facilitate the insertion of the first blocking block 100 and increase the contact area between the second blocking block 200 and the second pipe 2 and the half joint 3, thereby increasing the sealing performance of the connection between the second pipe 2 and the half joint 3 and further solving the leakage problem, the second blocking block 200 is a second wedge block, and the wedge-shaped end of the second wedge block is inserted in the second gap.

[0036] Continue as Figure 1 and Figure 2 As shown, in order to minimize the structural size of the gap blocking structure and thus reduce the occupied space, the two ends of the connecting component 300 are respectively connected to two opposite surfaces of the first blocking block 100 and the second blocking block 200 along the first direction.

[0037] Furthermore, two ends of the connection assembly 300 are respectively plugged into the first blocking block 100 and the second blocking block 200 , so the connection is simple and the connection strength is high.

[0038] Furthermore, the connection assembly 300 includes a first connection member 310 and a second connection member 320 that are connected to each other, which facilitates the separate installation of the first blocking block 100 and the second blocking block 200 and improves the installation efficiency.

[0039] In this embodiment, in order to facilitate the disassembly of the first connecting member 310 and the second connecting member 320, the first connecting member 310 and the second connecting member 320 are detachably connected.

[0040] Optionally, the first connecting member 310 is a sleeve, and the second connecting member 320 is a connecting rod, and the connecting rod is plugged into the sleeve, which is convenient for plug-in connection, has high connection strength, and has a compact structure.

[0041] In a preferred embodiment, the outer wall of the connecting rod is provided with an external thread, and the gap sealing structure also includes a nut, which is threadedly connected to the connecting rod and abuts against the end of the sleeve. The connection structure is strong and can adjust the distance between the first sealing block 100 and the second sealing block 200 along the first direction as needed.

[0042] In another embodiment, the gap sealing structure further includes bolts, which are radially penetrated through the sleeve and the connecting rod to connect the sleeve and the connecting rod, and have high connection strength.

[0043] It is worth mentioning that when implementing the plugging operation, first, it is necessary to enter the first pipeline 1 and the second pipeline 2 respectively to measure the sizes of the first gap and the second gap, and process the first blocking block 100 and the second blocking block 200 of corresponding sizes; then push the first blocking block 100 into the first gap, and push the second blocking block 200 into the second gap; then process deep grooves on the two opposite surfaces of the first blocking block 100 and the second blocking block 200 respectively; insert the first connecting piece 310 (sleeve) into the deep groove on the first blocking block 100, and after putting a nut on the second connecting piece 320 (connecting rod), insert one end into the sleeve and the other end into the deep groove on the second blocking block 200, and push the sleeve to fix the first blocking block 100 and the second blocking block 200 by tightening the nut.

[0044] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
