Description

Technical Field

[0001] This utility model relates to the technical field of pipeline compensators, and in particular to a bidirectional sealing sleeve type pipeline compensator. Background Technology

[0002] The bidirectional sealing sleeve type pipe compensator is a key device for flexible pipe connection and thermal compensation in the field of pipeline engineering. It is mainly used to solve the problems of axial, lateral displacement and angular deflection of pipelines caused by temperature changes, medium pressure fluctuations or installation errors.

[0003] Currently, among existing pipe compensators, such as the patent with announcement number CN220727506U, this utility model discloses a bidirectional sealing sleeve type pipe compensator, which relates to the field of pipe compensator technology. This pipe compensator aims to solve the technical problem that existing bidirectional pipe compensators are usually unable to be quickly installed with pipes of different diameters when connected to pipes, and it is difficult to reduce the flow velocity of water flowing into the pipe compensator.

[0004] Existing pipeline compensators have been found to require the external pipeline to be rotated as a whole when connecting the compensator to the external pipeline, which increases the complexity of installation and reduces the efficiency of loading and unloading the compensator. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a bidirectional sealing sleeve type pipe compensator that enables a sealed connection between the connecting pipe and the external pipeline, improves the convenience of installation and operation, limits the expansion and contraction of the bellows by the limiting device to avoid damage to the bellows due to excessive movement, and improves the movement compensation effect of the external pipeline connection.

[0006] This utility model discloses a bidirectional sealing sleeve-type pipe compensator, comprising a corrugated pipe and two sets of connecting plates, the two sets of connecting plates being disposed at both ends of the corrugated pipe; it also includes a limiting device, a pushing device, connecting pipes, semi-circular fittings, and sealing gaskets. The two sets of connecting pipes are respectively connected to the outer walls of the two sets of connecting plates, and the ends of the two sets of connecting pipes respectively contact the external pipelines on both sides. Each pair of semi-circular fittings is respectively fitted between one side of the connecting pipe and the external pipeline. The sealing gasket is disposed on the inner wall of the semi-circular fitting. The limiting device and the pushing device are respectively disposed between the two sets of connecting plates. The limiting device is used to limit the movement between the two sets of connecting plates, and the pushing device is used to push and support the two sets of connecting plates. The pipe is equipped with a filter screen. When the corrugated pipe needs to be installed, the ends of the two sets of connecting pipes are brought into contact with the external pipes on both sides. Then, the two sets of connecting plates are pushed to the sides by the pushing device, so that the two sets of connecting plates press the two sets of connecting pipes and the external pipes tightly. Then, the semi-circular kit is installed on the outer wall between the connecting pipes and the external pipes to achieve a sealed connection between the connecting pipes and the external pipes, improving the convenience of installation. After that, the pushing device is removed and the limiting device is installed between the two sets of connecting plates. The limiting device restricts the expansion and contraction and bending of the corrugated pipe, avoiding excessive movement that could damage the corrugated pipe, and improving the movement compensation effect of the external pipe connection.

[0007] Preferably, the pushing device includes a rotating seat, a first set screw, an internally threaded tube, a stud, and a polygonal assembly. The rotating seat is mounted on the outer wall of the left connecting plate. The first set screw is fitted onto the rotating seat. The internally threaded tube is rotatably mounted on the rotating seat. The stud is screwed onto the internally threaded tube, and an anti-slip pad is provided at the front end of the stud. The polygonal assembly is mounted on the outer wall of the internally threaded tube. The internally threaded tube is rotatably mounted on the rotating seat, and then the stud is rotated and moved so that the anti-slip pad at the front end of the stud presses against the right connecting plate. Then, the operator rotates the internally threaded tube through the polygonal assembly, thereby causing the internally threaded tube to push the stud to the right. This causes the internally threaded tube and the stud to cooperate in pushing the two sets of connecting plates, achieving a tight connection between the connecting pipes on both sides and the external pipeline. When the semi-circular assembly needs to be installed, the first set screw is first rotated to lock and fix the internally threaded tube, thereby preventing the internally threaded tube from rotating freely due to vibration during the installation of the semi-circular assembly, improving the reliability of the sealing connection of the connecting pipe. After the semi-circular assembly is installed, the internally threaded tube and the stud can be disassembled.

[0008] Preferably, the limiting device includes a crossbar, a sliding assembly, a second set screw, and an elastic ring. Two sets of connecting plates are provided with through holes, and the elastic ring is disposed within the through holes. The crossbar passes through the elastic rings, and a movable gap is provided between the crossbar and the elastic rings. Two sets of sliding assemblies are slidably mounted on the outer wall of the crossbar, and two sets of second set screws are respectively fitted onto the two sets of sliding assemblies. The crossbar is installed between the two sets of connecting plates through the elastic rings, and a gap is maintained between the installation positions of the two sets of sliding assemblies and the two sets of connecting plates. When the external pipelines on both sides shift, the bellows compensates for the shift. The crossbar and sliding assemblies cooperate to limit the movement of the two sets of connecting plates, thereby preventing excessive deformation of the bellows and damage.

[0009] Preferably, it also includes bolts and first nuts, which are installed together between multiple sets of semi-circular components; by using multiple sets of bolts and first nuts to fix the multiple sets of semi-circular components together, the ease of loading and unloading the multiple sets of semi-circular components is improved.

[0010] Preferably, it also includes a second nut, wherein every two sets of second nuts are respectively screwed onto both sides of the crossbar; the second nuts on both sides are pressed and fixed together to position the second nuts on both sides, thereby limiting the movement of the second nuts at both ends of the crossbar.

[0011] Preferably, it also includes sealing rings, with two sets of sealing rings respectively disposed at the ends of the two sets of connecting pipes; to improve the sealing performance of the connection between the two sets of connecting pipes and the external pipeline.

[0012] Preferably, the two sets of connecting pipes are equipped with filter screens to improve the filtration effect when the internal liquid passes through, thereby enhancing the functionality.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The two sets of connecting pipes are equipped with filter screens. When the corrugated pipe needs to be installed, the ends of the two sets of connecting pipes are brought into contact with the external pipes on both sides. Then, the two sets of connecting plates are pushed to opposite sides by the pushing device, thereby pressing the two sets of connecting pipes and the external pipes together. Then, the semi-circular kit is fitted and installed on the outer wall between the connecting pipe and the external pipe, achieving a sealed connection between the connecting pipe and the external pipe, improving the convenience of installation. Afterwards, the pushing device is disassembled and a limiting device is installed between the two sets of connecting plates, so that the limiting device restricts the expansion and contraction and bending of the corrugated pipe, avoiding excessive movement that could damage the corrugated pipe, while also improving the movement compensation effect of the external pipe connection.

Detailed Implementation

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0021] like Figures 1 to 5 As shown, the bidirectional sealing sleeve type pipe compensator of this utility model includes a corrugated pipe 1 and two sets of connecting plates 2, which are disposed at both ends of the corrugated pipe 1; it also includes a limiting device, a pushing device, a connecting pipe 3, a semi-circular kit 4 and a sealing gasket 5. The two sets of connecting pipes 3 are respectively connected and disposed on the outer side walls of the two sets of connecting plates 2, and the ends of the two sets of connecting pipes 3 are respectively in contact with the external pipelines on both sides. Each pair of semi-circular kits 4 are respectively fitted between the connecting pipe 3 on one side and the external pipeline. The sealing gasket 5 is disposed on the inner side wall of the semi-circular kit 4. The limiting device and the pushing device are respectively disposed between the two sets of connecting plates 2. The limiting device is used to limit the distance between the two sets of connecting plates 2, and the pushing device is used to push and support the two sets of connecting plates 2.

[0022] like Figure 1 As shown, the pushing device includes a rotating seat 6, a first set screw 7, an internally threaded tube 8, a stud 9, and a polygonal assembly 10. The rotating seat 6 is installed on the outer wall of the left connecting plate 2. The first set screw 7 is fitted on the rotating seat 6. The internally threaded tube 8 is rotatably installed on the rotating seat 6. The stud 9 is screwed onto the internally threaded tube 8, and an anti-slip pad is provided at the front end of the stud 9. The polygonal assembly 10 is installed on the outer wall of the internally threaded tube 8.

[0023] In this embodiment, the two sets of connecting pipes 3 are equipped with filters. When the corrugated pipe 1 needs to be installed, the ends of the two sets of connecting pipes 3 are brought into contact with the external pipes on both sides. Then, the two sets of connecting plates 2 are pushed to the sides by the pushing device, so that the two sets of connecting plates 2 push the two sets of connecting pipes 3 to press tightly against the external pipes. Then, the semi-circular kit 4 is installed on the outer side wall between the connecting pipe 3 and the external pipe to achieve a sealed connection between the connecting pipe 3 and the external pipe, improving the convenience of installation. Then, the pushing device is disassembled and the limiting device is installed between the two sets of connecting plates 2, so that the limiting device restricts the expansion and contraction and bending of the corrugated pipe 1, avoiding excessive movement that could damage the corrugated pipe 1, and improving the movement compensation effect of the external pipe connection. Example 2

[0024] Based on Example 1, such as Figure 3 As shown, the bidirectional sealing sleeve type pipe compensator of this utility model includes a limiting device comprising a crossbar 11, a sliding assembly 12, a second set screw 13, and an elastic ring 14. Two sets of connecting plates 2 are provided with through holes, and the elastic ring 14 is disposed in the through holes. The crossbar 11 passes through the elastic ring 14, and an movable gap is provided between the crossbar 11 and the elastic ring 14. Two sets of sliding assemblies 12 are respectively slidably installed on the outer side wall of the crossbar 11, and two sets of second set screws 13 are respectively fitted onto the two sets of sliding assemblies 12.

[0025] like Figure 2 As shown, it also includes bolt 15 and first nut 16, which are fitted together between multiple sets of semi-circular kits 4;

[0026] like Figure 3 As shown, it also includes a second nut 17, wherein every two sets of second nuts 17 are respectively screwed onto both sides of the crossbar 11;

[0027] like Figure 2 As shown, it also includes sealing rings 18, with two sets of sealing rings 18 respectively disposed at the ends of the two sets of connecting pipes 3;

[0028] like Figure 2 As shown, filters are installed inside the two sets of connecting pipes 3;

[0029] In this embodiment, the internally threaded tube 8 is rotatably mounted on the rotating seat 6. Then, the stud 9 is rotated and moved so that the anti-slip pad at the front end of the stud 9 presses against the right-side connecting plate 2. Next, the operator rotates the internally threaded tube 8 using the polygonal kit 10, causing the internally threaded tube 8 to push the stud 9 to the right. This allows the internally threaded tube 8 and the stud 9 to cooperate in pushing the two sets of connecting plates 2, achieving a tight connection between the connecting tubes 3 on both sides and the external pipeline. When it is necessary to install the semi-circular kit 4, the first set screw 7 is rotated to lock and fix the internally threaded tube 8, thereby preventing the semi-circular kit from being installed. 4. Vibration during installation causes the internally threaded pipe 8 to rotate freely, improving the reliability of the sealing connection of the connecting pipe 3. After the semi-circular kit 4 is installed, the internally threaded pipe 8 and the stud 9 can be disassembled. The crossbar 11 is passed through the elastic ring 14 and installed between the two sets of connecting plates 2. The installation position of the two sets of sliding kits 12 is kept at a gap with the two sets of connecting plates 2. When the external pipelines on both sides move or shift, the bellows 1 compensates for the movement and shift. The crossbar 11 and the sliding kit 12 cooperate to limit the two sets of connecting plates 2, thereby avoiding excessive deformation of the bellows 1 and damage.

[0030] This utility model of a bidirectional sealing sleeve-type pipe compensator involves the following steps during operation: When installing the corrugated pipe 1, the ends of the two sets of connecting pipes 3 are brought into contact with the external pipelines on both sides. Then, the two sets of connecting plates 2 are pushed to opposite sides by a pushing device, thereby pressing the two sets of connecting pipes 3 and the external pipelines together. Afterward, the semi-circular kit 4 is fitted and installed on the outer wall between the connecting pipe 3 and the external pipeline to achieve a sealed connection between the connecting pipe 3 and the external pipeline. Then, the pushing device is disassembled and a limiting device is installed between the two sets of connecting plates 2 to limit the expansion, contraction, and bending of the corrugated pipe 1.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
