Description

Technical Field

[0001] The utility model relates to the technical field of pressure compensators, and particularly relates to a pressure compensator. Background Art

[0002] In many industrial fields, the pressure stability of pipeline systems is crucial. However, in practical applications, due to the influence of various factors, the pressure within the pipeline system often changes, which may have a serious impact on the safe operation of the pipeline and the normal operation of equipment. Traditional connection methods often have deficiencies in dealing with pressure changes and are difficult to achieve effective pressure compensation, which may lead to problems such as leakage at the connection site and equipment damage. At the same time, the existing connection devices may be relatively complex during installation and disassembly, with inconvenient operation and unable to quickly achieve connection and fixation. To solve these problems, a new type of pressure compensator is needed that can quickly achieve connection and fixation in the pipeline system and effectively compensate for pressure changes to ensure the safe and stable operation of the pipeline system.

[0003] However, for traditional equipment, traditional connection methods often have deficiencies in dealing with pressure changes, are difficult to achieve effective pressure compensation, and may lead to problems such as leakage at the connection site and equipment damage. At the same time, the existing connection devices may be relatively complex during installation and disassembly, with inconvenient operation and unable to quickly achieve connection and fixation, and need to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems raised in the above background art.

[0005] The utility model adopts the following technical scheme: A pressure compensator includes a corrugated pipe. Both ends of the corrugated pipe are fixedly installed with connecting plates. Insertion holes are formed on the surfaces of the connecting plates. Insertion rods are sleeved inside the insertion holes. Bolts are threadedly connected to both ends of the insertion rods. Grooves are formed inside the connecting plates. Arc-shaped blocks are sleeved inside the grooves. A moving block is fixedly installed at the rear end of the arc-shaped block. Tooth blocks are formed on the surface of the moving block. A first gear is sleeved inside the groove. A first rotating rod is fixedly installed at the top of the first gear. A second gear is fixedly installed at the other end of the first rotating rod. An annular block is sleeved inside the groove. A first rack is fixedly installed on the inner surface of the annular block. A second rack is fixedly installed on the outer surface of the annular block. A third gear is sleeved inside the groove. A second rotating rod is fixedly installed at the top of the third gear. A rotating block is fixedly installed at the top of the second rotating rod. A silica gel tube is fixedly installed inside the groove.

[0006] Preferably, the surface of the first gear meshes with the surface of the tooth block, the surface of the second gear meshes with the surface of the first rack, and the surface of the second rack meshes with the surface of the third gear. Here, through the meshing of the first gear with the tooth block, the second gear with the first rack, and the second rack with the third gear, the transmission and linkage between components are realized. This design enables the operator to precisely control the movement of the arc block by rotating the rotating block, thereby adjusting the sealing performance and pressure compensation effect between the silicone tube and the connection part.

[0007] Preferably, the number of the arc blocks, moving blocks, first gears, and second gears is four groups and they are circumferentially distributed inside the groove. Here, the four groups of arc blocks, moving blocks, first gears, and second gears are circumferentially distributed in the groove, which can apply uniform pressure to the silicone tube from multiple directions, ensuring the stability and reliability of pressure compensation.

[0008] Preferably, the surface of the rotating block is provided with anti-slip lines, which are circumferentially distributed on the surface of the rotating block. Here, the anti-slip lines on the surface of the rotating block increase the friction force, facilitating the operator to rotate the rotating block, and improving the convenience and accuracy of operation. When the pressure compensator needs to be adjusted, the operator can operate more easily to ensure that the pressure compensation effect meets the actual requirements.

[0009] Preferably, the front end of the silicone tube is conical in shape, and the number of the silicone tubes is two groups and they are symmetrically distributed on the surface of the corrugated pipe. Here, the front end of the silicone tube is conical, which is convenient for better fitting with the connection part and improving the sealing performance. The two groups of silicone tubes are symmetrically distributed on the surface of the corrugated pipe, which can bear the pressure more evenly and improve the pressure compensation effect. At the same time, the material of the silicone tube has good elasticity and corrosion resistance, and can adapt to different working environments.

[0010] Preferably, the surface of the connecting plate is provided with a sliding groove, a moving rod is sleeved inside the sliding groove, a spring is sleeved on the outer surface of the moving rod, a closing cover is sleeved on the outer surface of the top end of the moving rod, and a rotating groove is provided on the surface of the closing cover. Here, the combination of the moving rod, spring, and closing cover provides protection for the bolt. The closing cover can prevent the bolt from being affected by the external environment, such as dust, corrosion, etc., and extend the service life of the bolt. At the same time, the elasticity of the spring can enable the closing cover to automatically adapt to different connection states within a certain range, ensuring the sealing performance of the closing cover.

[0011] Preferably, one end of the spring is fixedly connected to the surface of the moving rod, and the other end of the spring is fixedly connected to the surface of the sliding groove. Here, the spring connects the moving rod and the sliding groove, providing an elastic restoring force for the closing cover. When the closing cover is opened or closed, the spring can make the closing cover automatically reset, improving the convenience of operation. At the same time, the elasticity of the spring can also enable the closing cover to better adapt to bolts of different sizes, improving the versatility.

[0012] Preferably, the closing cover is sleeved on the outer surface of the bolt, and the number of the closing covers is four groups. Here, the four groups of closing covers are respectively sleeved on the outer surface of the bolt, which can comprehensively protect the bolt and ensure the stability and sealing performance of the connection part of the pressure compensator. At the same time, the design of multiple closing covers also improves the overall aesthetics of the pressure compensator.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

In the present utility model, by arranging a corrugated pipe, a connecting plate, an insertion hole, an insertion rod, a bolt, a groove, an arc-shaped block, a moving block, a toothed block, a first gear, a first rotating rod, a second gear, and an annular block structure, during the use of the device, by arranging a first gear, a second gear, a first rotating rod, a second rotating rod, a third gear, and an annular block structure, effective pressure compensation can be achieved when dealing with pressure changes, effectively preventing leakage at the connection part and equipment damage that may be caused. At the same time, during the installation and disassembly process, through the coordinated movement of multiple structures, the installation and disassembly can be simple and fast, so as to quickly achieve connection and fixation, effectively improving the quickness and convenience of the device. By arranging a silica gel tube and an arc-shaped block, the sealing performance of the device can be effectively improved, effectively preventing leakage.

A first rack 14 is fixedly installed on the inner surface of the annular block 13. A second rack 15 is fixedly installed on the outer surface of the annular block 13. A third gear 16 is sleeved inside the grooves 6. A second rotating rod 17 is fixedly installed at the top of the third gear 16. A rotating block 18 is fixedly installed at the top of the second rotating rod 17. A silica gel tube 19 is fixedly installed inside the grooves 6. First of all, the connecting plates 2 at both ends of the corrugated pipe 1 play a role of connection and support. The insertion rod 4 is sleeved into the insertion holes 3 on the connecting plates 2, and then preliminary fixed connection is carried out through the bolts 5 at both ends of the insertion rod 4. When quick connection and fixation are required, the operator rotates the rotating block 18, and the rotating block 18 drives the second rotating rod 17 to rotate, thereby causing the third gear 16 to rotate. The third gear 16 meshes with the second rack 15 on the outer surface of the annular block 13, driving the annular block 13 to move. The first rack 14 on the inner surface of the annular block 13 meshes with the second gear 12, causing the second gear 12 to rotate, thereby driving the first rotating rod 11 to rotate, and making the first gear 10 rotate accordingly. The first gear 10 meshes with the tooth blocks 9 on the surface of the moving block 8, pushing the moving block 8 to move, and the moving block 8 drives the arc-shaped block 7 to move inside the groove 6 of the connecting plate 2. As the arc-shaped block 7 moves, the arc-shaped block 7 gradually squeezes the silica gel tube 19 inside the groove 6. Under the extrusion of the arc-shaped block 7, the silica gel tube 19 is closely attached to the connection part, realizing quick connection and fixation.

[0027] Please refer to Figures 1 - 5 , the surface of the first gear 10 meshes with the surface of the tooth block 9, the surface of the second gear 12 meshes with the surface of the first rack 14, the surface of the second rack 15 meshes with the surface of the third gear 16. The number of the arc-shaped blocks 7, moving blocks 8, first gears 10, and second gears 12 is four groups each and they are circumferentially distributed inside the groove 6. Anti-slip lines 20 are provided on the surface of the rotating block 18, and the anti-slip lines 20 are circumferentially distributed on the surface of the rotating block 18. The front end shape of the silica gel tube 19 is conical. The number of the silica gel tubes 19 is two groups and they are symmetrically distributed on the surface of the corrugated pipe 1. One end of a spring 23 is fixedly connected to the surface of a moving rod 22, and the other end of the spring 23 is fixedly connected to the surface of a sliding groove 21. By setting the spring 23, it is convenient for the staff to disassemble the equipment. A closing cover 24 is sleeved on the outer surface of the bolt 5, and the number of the closing covers 24 is four groups.

[0028] Example Two

[0029] Please refer to Figure 4 , a sliding groove 21 is formed on the surface of the connecting plate 2. A moving rod 22 is sleeved inside the sliding groove 21. A spring 23 is sleeved on the outer surface of the moving rod 22. A closing cover 24 is sleeved on the outer surface of the top end of the moving rod 22. A rotating groove 25 is formed on the surface of the closing cover 24. When it is necessary to protect or operate the bolt 5, the moving rod 22 moves in the sliding groove 21 on the surface of the connecting plate 2. The movement of the moving rod 22 drives the closing cover 24 sleeved on the outer surface of its top end to move. The rotating groove 25 on the closing cover 24 facilitates the rotating operation of the closing cover 24 by the operator. During the movement of the moving rod 22, the spring 23 sleeved on its outer surface will be compressed or extended according to the position of the moving rod 22. When the closing cover 24 is opened, the spring 23 is compressed; when it is necessary to close the closing cover 24, the spring 23 extends, pushing the moving rod 22 and the closing cover 24 back to the initial position, so that the closing cover 24 tightly covers the bolt 5, playing a role in protecting the bolt 5 and preventing the bolt 5 from being affected by the external environment, such as dust and corrosion.

[0030] Working principle: When the staff connects the pipelines, first, the hand contacts the surface of the anti-slip pattern 20, and then rotates the rotating block 18. The rotating block 18 drives the second rotating rod 17 to rotate, and further rotates the third gear 16. The third gear 16 meshes with the second rack 15 on the outer surface of the annular block 13, driving the annular block 13 to move. The first rack 14 on the inner surface of the annular block 13 meshes with the second gear 12, causing the second gear 12 to rotate, thereby driving the first rotating rod 11 to rotate and making the first gear 10 rotate accordingly. The first gear 10 meshes with the tooth block 9 on the surface of the moving block 8, pushing the moving block 8 to move. The moving block 8 drives the arc-shaped block 7 to move in the groove 6 of the connecting plate 2. As the arc-shaped block 7 moves, the arc-shaped block 7 gradually squeezes the silica gel tube 19 in the groove 6. Under the extrusion of the arc-shaped block 7, the silica gel tube 19 is closely attached to the connection part, realizing rapid connection and fixation. When it is necessary to protect or operate the bolt 5, the moving rod 22 moves in the sliding groove 21 on the surface of the connecting plate 2. The movement of the moving rod 22 drives the closing cover 24 sleeved on the outer surface of its top end to move. The rotating groove 25 on the closing cover 24 facilitates the rotating operation of the closing cover 24 by the operator. During the movement of the moving rod 22, the spring 23 sleeved on its outer surface will be compressed or extended according to the position of the moving rod 22. When the closing cover 24 is opened, the spring 23 is compressed; when it is necessary to close the closing cover 24, the spring 23 extends, pushing the moving rod 22 and the closing cover 24 back to the initial position, so that the closing cover 24 tightly covers the bolt 5, playing a role in protecting the bolt 5 and preventing the bolt 5 from being affected by the external environment, such as dust and corrosion.

[0031] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
