Description

Technical Field

[0001] This utility model relates to the field of pipe clamps, specifically a bidirectional butt joint sealing pipe clamp. Background Technology

[0002] In the field of pipe connections, achieving bidirectional connection between two pipes while ensuring a tight seal is a critical requirement. Traditional pipe connection methods have many limitations:

[0003] Insufficient sealing performance: Some traditional connection methods fail to create a reliable and durable seal at pipe joints. For example, some simple socket or plain-end connections, relying solely on the adhesion of the pipe material or simple sealing materials, are prone to seal failure when faced with changes in fluid pressure, temperature fluctuations, and material aging after long-term use, leading to fluid leakage. This not only wastes resources but may also pollute the surrounding environment. If the fluid being transported is corrosive or hazardous, it can even cause safety accidents.

[0004] Poor connection stability: Some traditional pipeline connection structures lack effective limiting and fixing devices. When the pipeline is subjected to external forces, such as vibration, impact, or foundation settlement, the pipeline is prone to detachment from the connection or relative displacement, thereby disrupting the normal operation of the pipeline system. Especially in some applications where the reliability of pipeline connections is highly demanding, such as fluid transportation pipelines in industrial production and urban water and gas supply pipelines, this unstable connection method can seriously affect production and residents' lives.

[0005] Installation is complex and inefficient: Some traditional pipe connection methods are cumbersome to operate, requiring specialized technicians and complex installation tools, and the installation process is time-consuming. This not only increases installation costs but also reduces the construction efficiency of the pipeline system, hindering the rapid progress of the project. For example, some welded connection methods require on-site welding operations, which demand high levels of welding skills and operator expertise, and quality inspection is also required after welding, making the entire process quite complex. Utility Model Content

[0006] The purpose of this invention is to provide a bidirectional butt joint sealing pipe clamp to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bidirectional butt joint sealing pipe clamp, comprising a plug pipe, the two ends of which are respectively inserted into two pipes, a connecting ring fixedly fitted on the pipe body of the plug pipe, two clamp plates fixed on both sides of the connecting ring, the two clamp plates being connected by bolts, and the two clamp plates clamping the pipes.

[0008] Preferably, sealing gaskets are fixed on both sides of the connecting ring. The sealing gaskets have an annular plate structure and are sandwiched between the pipe and the connecting ring.

[0009] Preferably, the hoop plate has notches at both ends on the side near the connecting ring.

[0010] Preferably, bolt holes are provided at both ends of the hoop plate, and the bolts are locked after passing through the bolt holes on the surfaces of the two hoop plates.

[0011] Preferably, a rubber pad is fixed to the inner ring surface of the hoop, and the rubber pad is clamped between the hoop and the pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention proposes a bidirectional butt joint sealing pipe clamp. By setting annular plate-shaped sealing gaskets on both sides of the connecting ring, when two pipes are respectively fitted onto the ends of the plug and pushed against one side of the connecting ring, the sealing gaskets are compressed by the pipes. The sealing gaskets, utilizing their own elastic deformation, can tightly fill the gap between the pipes and the connecting ring, effectively preventing fluid leakage. This sealing method is less affected by changes in fluid pressure and temperature within the pipe, maintaining good sealing performance for a longer period, greatly improving the safety and reliability of pipe connections.

[0014] Two clamping plates fixed on both sides of the connecting ring are connected by bolts and clamped onto the pipe. The cleverly designed notches at both ends of the clamping plates near the connecting ring cause the ends of the two clamping plates to be pulled closer together during bolt tightening, tightly gripping the pipe and effectively limiting its movement. This structure can withstand certain external forces, such as pipe vibration, impact, or minor foundation settlement, preventing the pipe from detaching from the plug end, ensuring the stability of the pipe connection, and guaranteeing the long-term stable operation of the pipeline system.

[0015] The installation is simple: just slip two pipes over the ends of the plug, push the pipes against one side of the connecting ring, then place two clamps on the top and bottom sides of the pipes, pass bolts through, and tighten. The entire installation process is quick and convenient, significantly shortening the construction cycle of the piping system, reducing installation costs, and improving work efficiency.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a bidirectional butt joint sealing pipe clamp, comprising a plug tube 1, with both ends of the plug tube 1 inserted into two pipes 9 respectively. A connecting ring 2 is fixedly fitted onto the body of the plug tube 1, and sealing gaskets 8 are fixed on both sides of the connecting ring 2. The sealing gaskets 8 have an annular plate structure and are sandwiched between the pipes 9 and the connecting ring 2. When the two pipes 9 are connected, the two pipes 9 are respectively fitted onto both ends of the plug tube 1, and the pipes 9 are pushed against one side of the connecting ring 2. At this time, the sealing gaskets 8 are squeezed by the pipes 9, ensuring the sealing of the pipes 9 after they are fitted onto the plug tube 1.

[0025] Two clamping plates 3 are fixed on both sides of the connecting ring 2. The two clamping plates 3 are connected by bolts 5 and clamp the pipe 9. The clamping plates 3 have notches 7 at both ends on the side near the connecting ring 2. Bolt holes 4 are opened at both ends of the clamping plates 3. The bolts 5 pass through the bolt holes 4 on the surface of the two clamping plates 3 and are locked. A rubber pad 6 is fixed on the inner ring surface of the clamping plates 3 and is clamped between the clamping plates 3 and the pipe 9. When the pipe 9 is fitted onto the end of the plug tube 1, the two clamping plates 3 are distributed on the upper and lower sides of the pipe 9. The bolts 5 are passed through the bolt holes 4 on the surface of the two clamping plates 3 and locked. Since the clamping plates 3 have notches 7 on the side near the connecting ring 2, the ends of the two clamping plates 3 are pulled closer during the locking process of the bolts 5. That is, the two clamping plates 3 tightly hold the pipe 9, thereby limiting the pipe 9 and preventing the pipe 9 from falling off the end of the plug tube 1. The addition of the rubber pad 6 increases the friction between the pipe 9 and the clamping plates 3.

[0026] Instructions for using the bidirectional butt-connected sealing pipe clamp: Place two pipes 9 onto both ends of the plug pipe 1. During operation, slowly and steadily push the pipes 9 towards the plug pipe 1, ensuring accurate insertion. Push the pipes 9 so they press against one side of the connecting ring 2. At this point, the annular plate-shaped sealing gaskets 8 on both sides of the connecting ring 2 are compressed by the pipes 9. The elastic deformation of the sealing gaskets 8 fills the gap between the pipes 9 and the connecting ring 2, ensuring a tight seal after the pipes 9 are fitted onto the plug pipe 1 and preventing fluid leakage. Place the two clamp plates 3, fixed on both sides of the connecting ring 2, on the upper and lower sides of the fitted pipes 9. Ensure the clamp plates 3 are accurately positioned, with the side of the clamp plate 3 closest to the connecting ring 2 fitting against it, and aligning the two clamp plates 3 with the pipes 9, preparing for subsequent connection and fixation. Pass the bolts 5 through the bolt holes 4 at both ends of the two clamp plates 3. When inserting the bolts 5, ensure they pass smoothly, avoiding jamming or misalignment, and ensuring the precision of the fit between the bolts 5 and the bolt holes 4. Tighten the bolts 5 using appropriate tools. During the tightening process, because the clamp plate 3 has a notch 7 on the side near the connecting ring 2, as the bolt 5 is gradually tightened, the ends of the two clamp plates 3 are pulled closer together, thus tightly holding the pipe 9 and limiting the pipe 9 to prevent it from falling off the end of the plug pipe 1. A rubber pad 6 is fixed to the inner ring surface of the clamp plate 3. During the clamp plate 3's tightening of the pipe 9, the rubber pad 6 is squeezed between the clamp plate 3 and the pipe 9. The rubber pad 6 not only increases the friction between the pipe 9 and the clamp plate 3, further preventing the pipe 9 from loosening and falling off, but also plays a certain sealing role, enhancing the overall sealing performance of the clamp connection. After installation, the fit of the rubber pad 6 can be checked to ensure it is evenly and tightly fitted between the pipe 9 and the clamp plate 3. After completing all the above steps, a comprehensive inspection of the entire bidirectional butt joint sealing clamp connection is carried out. This includes checking whether the pipe 9 and the plug pipe 1 are securely connected, whether the sealing gasket 8 is fully compressed, whether the clamp plate 3 is tightly fixed to the pipe 9, and whether the bolt 5 is tightened without loosening.

[0027] Once confirmed to be correct, the bidirectional butt joint sealing clamp can be put into use to connect the two pipes 9 and ensure the sealing and stability of the connection.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
