Description

Technical Field

[0001] The utility model belongs to the technical field of pressure pipeline maintenance, and particularly relates to a pressure pipeline maintenance tooling. Background Technique

[0002] With the acceleration of the industrialization process, pressure pipelines are widely used in various industrial fields, such as petroleum, chemical industry, water supply and gas supply, etc. However, during the long-term use of pressure pipelines, due to external force impact, corrosion and other reasons, they often suffer from breakage or leakage. The existing repair methods mainly include two ways: welding repair and pipeline replacement. Welding repair requires professional equipment and personnel, with complex operations and high costs; pipeline replacement requires shutdown construction, resulting in significant economic losses. Therefore, it is particularly important to develop a convenient and efficient pressure pipeline maintenance tooling.

[0003] In practical applications, some complex maintenance situations are often encountered. For example, the ground source heat pump unit of a villa is usually installed in the basement. Due to the humid indoor environment, the pipeline insulation is severely damaged. After the unit has been used for a long time, the pipeline is severely corroded. Leakage points are prone to appear at the elbows, and the leakage points at the elbows cannot be repaired by welding, and clamps cannot be used for the elbows. Replacing the pipeline involves the welding of copper and steel, and the pipeline is located inside the unit, without enough construction space. Content of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a pressure pipeline maintenance tooling, which can achieve convenient maintenance and effectively improve the sealing performance and pressure resistance after repair.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pressure pipeline maintenance tooling includes a first pipe fitting and a second pipe fitting, and the first pipe fitting and the second pipe fitting are fixed on the pipeline bend through bolts;

[0007] First flow guiding members are arranged at equal intervals on the inner side of the first pipe fitting, second flow guiding members are arranged at equal intervals on the inner side of the second pipe fitting, and the first flow guiding members and the second flow guiding members are staggered with each other;

[0008] A lining piece covering the damaged part is arranged between the first pipe fitting and the second pipe fitting;

[0009] One end of the first pipe fitting is fixedly connected with a first glue injection pipe on the outer side, and one end of the second pipe fitting is fixedly connected with a second glue injection pipe on the outer side.

[0010] Furthermore, a first connection seat is fixedly connected to the outer edge of the first pipe fitting, and a first connection hole is penetrated through the upper end surface of the first connection seat;

[0011] A second connecting seat is fixedly connected to the outer edge of the second pipe fitting, and a second connecting hole is penetratingly formed in the upper end surface of the second connecting seat.

[0012] Furthermore, sealing caps are connected to both the first glue injection pipe and the second glue injection pipe, and anti-slip grooves are formed on the outer sides of the sealing caps.

[0013] Furthermore, sealing rings are clamped at both inner ends of the first pipe fitting and the second pipe fitting.

[0014] Furthermore, the sealing ring includes semi-circular members, the number of the semi-circular members is set to two, and the two semi-circular members are clamped with each other.

[0015] Furthermore, a splicing head is fixedly connected to one end of the semi-circular member, and a splicing groove is formed in the other end of the semi-circular member.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] The pressure pipeline repair tooling in the present utility model is simply designed and quick to operate, and can effectively improve the sealing performance and pressure resistance after repair. Through the structural design of the first pipe fitting and the second pipe fitting, it can be fixed on the pipe bend by bolts, thus solving the problem of insufficient sealing performance in the prior art. The design of using the sealing ring ensures the tight connection between the first pipe fitting and the second pipe fitting and the pipeline, and prevents the repaired pipeline from leaking under high pressure.

[0018] The design of the diversion member in the present utility model enables cement or glue to be evenly distributed between the first pipe fitting and the second pipe fitting, thereby enhancing the repair effect. The staggered arrangement of the first diversion member and the second diversion member ensures that the filling material can be evenly distributed at the damaged part of the pipeline, improving the overall strength and pressure resistance of the pipeline. This design effectively solves the problem that the filling material is not easily evenly distributed in the prior art.

[0019] The present utility model is designed with the first connecting seat and the second connecting seat, and is fastened by bolts, which is simple to operate and can be quickly installed. The settings of the first connecting hole and the second connecting hole ensure the stability during the installation process, improving the adaptability and versatility of the repair tooling. This structural design not only simplifies the installation process, but also reduces the operation difficulty and time cost, solving the problem of complex installation process in the prior art.

[0020] The anti-slip groove design of the sealing cap enables the sealing cap to be conveniently unscrewed or tightened during operation, preventing hand slippage. Through the design of the first glue injection pipe and the second glue injection pipe, cement or glue can be injected into the space between the first pipe fitting and the second pipe fitting, ensuring uniform distribution of the filler between the first pipe fitting and the second pipe fitting. After the glue injection is completed, the sealing cap can effectively seal the glue injection pipe, preventing cement or glue from overflowing and improving the sealing effect after repair.

[0021] Through the splicing design of the semi-circular parts, the sealing ring can be conveniently installed at the pipe bend. The design of the splicing joint and the splicing groove enables the semi-circular parts to be firmly connected into a complete sealing ring, ensuring that the sealing ring is not easily detached after installation, thereby improving the sealing effect. This design effectively solves the problem of unreasonable design of the sealing ring in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Referring to Figure 1-3 , a first connection seat 12 is fixedly connected to the outer edge of the first pipe fitting 1; a first connection hole 121 is penetrated through the upper end surface of the first connection seat 12; a second connection seat 22 is fixedly connected to the outer edge of the second pipe fitting 2; a second connection hole 221 is penetrated through the upper end surface of the second connection seat 22; through the first connection hole 121 and the second connection hole 221, bolts are used to fasten the first connection seat 12 and the second connection seat 22; this structure can ensure that the first pipe fitting 1 and the second pipe fitting 2 can be stably fixed on the pipe elbow during installation; during use, by tightening the bolts, the first pipe fitting 1 and the second pipe fitting 2 are tightly buckled, so as to ensure that the repaired pipeline will not leak under high pressure.

[0037] Referring to Figure 5, sealing caps 4 are connected to both the first glue injection pipe 13 and the second glue injection pipe 23; anti-slip grooves 41 are provided on the outer side of the sealing caps 4; this design enables the sealing caps 4 to be easily unscrewed or tightened during operation to prevent hand slippage; through the first glue injection pipe 13 and the second glue injection pipe 23, cement or glue can be injected into the space between the first pipe fitting 1 and the second pipe fitting 2; the sealing caps 4 can effectively seal the glue injection pipes after the glue injection is completed to prevent cement or glue from overflowing and ensure that the filler is evenly distributed between the first pipe fitting 1 and the second pipe fitting 2.

[0038] Refer to Figure 1 and Figure 4 , sealing rings 5 are snap-fitted at both inner ends of the first pipe fitting 1 and the second pipe fitting 2; the sealing rings 5 are composed of semi-circular parts 51, the number of the semi-circular parts 51 is set to two, and the two semi-circular parts 51 are snap-fitted with each other; during installation, first, the two semi-circular parts 51 are snap-fitted into a complete sealing ring 5, and then the sealing ring 5 is installed at the pipe bend; this design can ensure that the sealing ring 5 is at both inner ends when fastening the first pipe fitting 1 and the second pipe fitting 2, so as to effectively seal the damaged part of the pipeline.

[0040] The working principle of the present utility model is:

[0041] When in use, first, it is necessary to clean the damaged part at the pipe bend of the pipeline with sandpaper, then apply glue to the damaged part, cut the lining piece 3, then cover it on the damaged pipeline, then install the sealing ring 5 on the bend pipe, and buckle the first pipe fitting 1 and the second pipe fitting 2 on the bend pipe. When buckling the first pipe fitting 1 and the second pipe fitting 2, the sealing ring 5 should be at both inner ends of the first pipe fitting 1 and the second pipe fitting 2. Then, use bolts to fasten the first connection seat 12 and the second connection seat 22. As the bolts are tightened, the first pipe fitting 1 and the second pipe fitting 2 will be tightly connected together. And because sealing rings 5 are provided at both inner ends of the first pipe fitting 1 and the second pipe fitting 2, the sealing rings 5 provided can make the first pipe fitting 1 and the second pipe fitting 2 tightly connected to the pipeline.

[0042] After the first pipe fitting 1 and the second pipe fitting 2 are fixed on the leaking pipeline, cement or curable glue is then poured into the space between the first pipe fitting 1 and the second pipe fitting 2 through the second glue injection pipe 23. The staggered first flow guiding member 11 and the second flow guiding member 21 can make the connection between the cement or glue and the first pipe fitting 1 and the second pipe fitting 2 more firm, and the filler can also improve the compressive resistance of the damaged part.

[0043] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
