Description

Oil pipe compensator convenient for installation

Technical Field

The utility model relates to the technical field of oil pipe compensators, in particular to an oil pipe compensator which is easy to install.

Background technique

The tubing compensator, also known as the bellows expansion joint and compensator, is a common axial bellows expansion joint that is used to compensate for the axial length of the pipeline. It is installed and fixed with a connecting ring at one end of the equipment pipeline. It can be used to compensate for the angular deformation and lateral deformation of the pipeline. The tubing compensator uses its own elastic expansion function to compensate for the axial, angular, lateral and combined displacement of the pipeline caused by thermal deformation, mechanical deformation and various mechanical vibrations, thereby reducing the distortion and rupture of the pipeline caused by mechanical deformation.

The existing oil pipe compensator connects and fixes the connecting pipe of the oil pipe compensator to the connecting ring at one end of the equipment pipeline by bolts. The connection position between the connecting pipe and the connecting ring is a smooth plane. After the two sets of cross sections of the connecting pipe and the connecting ring are connected by bolts, a gap is inevitably generated at the connection position. The generation of the gap easily leads to poor sealing effect of the oil pipe compensator, making it difficult to achieve a better sealing connection effect.

Utility Model Content

The utility model aims to provide an oil pipe compensator which is easy to install, so as to solve the problem of poor sealing effect between the connecting pipe of the oil pipe compensator on the market and the connecting ring at one end of the equipment pipeline proposed in the above background technology.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oil pipe compensator that is easy to install, comprising a corrugated pipe, a connecting pipe, a fixing block, a limiting groove and a bolt, a connecting pipe is arranged at the top of the corrugated pipe, a fixing block is arranged on the outer wall of the connecting pipe, a limiting groove is provided inside the connecting pipe, a bolt is sleeved inside the limiting groove, and a sealing ring is sleeved on the outer wall of the bolt located on one side of the connecting pipe.

Preferably, a nut is sleeved on the outer wall of one end of the bolt, and a sealing gasket is sleeved on the outer wall of the bolt located inside the limiting groove.

Preferably, there are two groups of connecting pipes.

Preferably, a threaded rod is sleeved inside the fixing block, two groups of first positioning blocks are sleeved on the outer wall of the threaded rod located inside the fixing block, and second positioning blocks are sleeved on the outer walls at both ends of the threaded rod.

Preferably, a hexagonal groove engaging with one end of a bolt is formed at one end of the inner wall of the limiting groove.

Preferably, three groups of fixing blocks are provided on the outer wall of a group of the connecting pipes.

Compared with the prior art, the beneficial effects of the utility model are:

1. When the operator needs to install and connect the tubing compensator to the equipment pipeline, the operator inserts the end of the connecting pipe away from the corrugated pipe into the equipment pipeline, and the operator passes the bolt through the limit groove, the sealing ring and the connecting ring of the pipeline, and connects the nut and the bolt through a thread, so that the connecting pipe and the equipment pipeline are fixed by the nut and the bolt, and the connecting pipe pushes the sealing ring to fit the equipment pipeline, so that a sealed state is formed between the equipment pipeline and the tubing compensator, so that the tubing compensator is not prone to leakage during operation. By setting the sealing ring, nut and bolt, the sealing performance of the tubing compensator is improved after being connected to the equipment pipeline, which can improve the sealing effect of the tubing compensator. By setting the bolts, limit grooves, sealing rings, nuts and connecting pipes, the tubing compensator has a better sealing effect after installation and a better use effect.

2. When the operator needs to use the oil pipe compensator to compensate the axial length of the equipment pipeline, the operator rotates the first positioning block forward, and the first positioning block moves forward on the outer wall of the threaded rod. The distance between the first positioning block and the fixed block becomes larger, and the first positioning block moves to the position of the allowable compensation amount and stops. When the equipment pipeline becomes longer, the connecting ring of the equipment pipeline pushes the connecting pipe to descend, and the descent of the connecting pipe pushes the corrugated pipe to compress, and the connecting pipe drives the fixed block to slide on the outer wall of the threaded rod. The first positioning block limits the position of the fixed block, and the corrugated pipe is compressed or deformed, which is convenient for compensating the pipeline. By setting a hexagonal groove that engages with one end of the bolt at one end of the inner wall of the limiting groove, one end of the bolt is located inside the limiting groove, reducing the probability of the corrugated pipe touching and rubbing with the corners of the bolt during elastic expansion or deformation, effectively improving the service life of the corrugated pipe, and the hexagonal groove on the inner wall of the limiting groove is engaged with one end of the bolt, reducing the contact between the corrugated pipe and one end of the bolt, which is convenient for the long-term operation of the oil pipe compensator.

Implementation

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4. The utility model provides a technical solution: an oil pipe compensator that is easy to install, including a corrugated pipe 1, a connecting pipe 2, a fixing block 3, a limiting groove 4 and a bolt 5. The top of the corrugated pipe 1 is provided with a connecting pipe 2, the outer wall of the connecting pipe 2 is provided with a fixing block 3, the interior of the connecting pipe 2 is provided with a limiting groove 4, the interior of the limiting groove 4 is provided with a bolt 5, and the outer wall of the bolt 5 is located on one side of the connecting pipe 2 and is provided with a sealing ring 501.

1 , 2 , 3 and 4 , a nut 502 is sleeved on the outer wall of one end of the bolt 5 , a sealing gasket 503 is sleeved on the outer wall of the bolt 5 located inside the limiting groove 4 , and the nut 502 is threadedly connected to the bolt 5 .

During specific implementation, when the operator needs to install and connect the oil pipe compensator to the equipment pipeline, the operator inserts the end of the connecting pipe 2 away from the corrugated pipe 1 into the equipment pipeline, and the operator passes the bolt 5 through the limit groove 4, the sealing ring 501 and the connecting ring of the pipeline, and threadedly connects it with the bolt 5 through the nut 502, so that the connecting pipe 2 and the equipment pipeline are fixed by the nut 502 and the bolt 5, and the connecting pipe 2 pushes the sealing ring 501 to fit between the equipment pipeline, so that a sealed state is formed between the equipment pipeline and the oil pipe compensator, so that the oil pipe compensator is not prone to leakage during operation. By setting the sealing ring 501, the nut 502 and the bolt 5, the sealing of the oil pipe compensator after being connected to the equipment pipeline is improved, which can improve the sealing effect of the oil pipe compensator.

1 and 2 , it can be seen that there are two groups of connecting pipes 2 , and the two groups of connecting pipes 2 are located at the top and bottom ends of the corrugated pipe 1 .

During specific implementation, two groups of connecting pipes 2 are connected to the connecting rings of the equipment pipeline to facilitate installation between the oil pipe compensator and the equipment pipeline.

Referring to Figures 1, 2, 3 and 4, it can be seen that a threaded rod 301 is sleeved inside the fixing block 3, and two sets of first positioning blocks 302 are sleeved on the outer wall of the threaded rod 301 located on the inner side of the fixing block 3, and second positioning blocks 303 are sleeved on the outer walls at both ends of the threaded rod 301, the first positioning blocks 302 are threadedly connected to the threaded rod 301, the second positioning blocks 303 are threadedly connected to the threaded rod 301, and the fixing block 3 is slidably connected to the threaded rod 301.

During specific implementation, when the operator needs to use the oil pipe compensator to compensate the axial length of the equipment pipeline, the operator rotates the first positioning block 302 forward, and the first positioning block 302 rotates forward to move on the outer wall of the threaded rod 301, and the distance between the first positioning block 302 and the fixed block 3 becomes larger. The first positioning block 302 moves to the position of the allowed compensation amount and stops. When the equipment pipeline becomes longer, the connecting ring of the equipment pipeline pushes the connecting pipe 2 to descend, and the descending connecting pipe 2 pushes the corrugated pipe 1 to compress, and the connecting pipe 2 drives the fixed block 3 to slide on the outer wall of the threaded rod 301. Block 302 limits the position of the fixed block 3, and the corrugated pipe 1 is compressed or deformed, which is convenient for compensating the pipe. The oil pipe compensator uses its own elastic expansion and contraction function to compensate for the axial, angular, lateral and combined displacements of the pipe caused by thermal deformation, mechanical deformation and various mechanical vibrations. A hexagonal groove is provided at one end of the inner wall of the limiting groove 4 to engage with one end of the bolt 5, so that one end of the bolt 5 is located inside the limiting groove 4, thereby reducing the probability of the corrugated pipe 1 touching and rubbing with the corners of the bolt 5 during the process of elastic expansion and contraction or deformation, thereby effectively improving the service life of the corrugated pipe 1.

As can be seen from FIG. 2 , a hexagonal groove for engaging with one end of a bolt 5 is formed at one end of the inner wall of the limiting groove 4 .

In specific implementation, one end of the bolt 5 is limited by the hexagonal groove, thereby preventing the corrugated pipe 1 from being deformed and causing friction damage when doing work.

1 , 2 and 3 , it can be seen that three groups of fixing blocks 3 are disposed on the outer wall of a group of connecting pipes 2 . The three groups of fixing blocks 3 are located on the outer wall of the connecting pipes 2 and are distributed in a circular manner with equal intervals.

To sum up: when the operator needs to connect the oil pipe compensator with the equipment pipeline, the operator inserts the end of the connecting pipe 2 away from the corrugated pipe 1 into the equipment pipeline, and the operator passes the bolt 5 through the limit groove 4, the sealing ring 501 and the connecting ring of the pipeline, and threadedly connects the bolt 5 with the nut 502, so that the connecting pipe 2 and the equipment pipeline are fixed through the nut 502 and the bolt 5, and the sealing ring 501 forms a sealing state between the equipment pipeline and the oil pipe compensator. Through the elastic expansion and contraction function of the oil pipe compensator itself, the axial, angular, lateral and combined displacements of the pipeline caused by thermal deformation, mechanical deformation and various mechanical vibrations are compensated. As a compensation element, the oil pipe compensator utilizes the effective expansion and contraction deformation of its working body, the corrugated pipe, to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, and compensates for the length of the pipeline.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
