Technical Field
[0001] This utility model relates to the field of heating pipeline structure technology, specifically a heating pipeline connection structure. Background Technology
[0002] The heating network is a crucial part of a centralized heating system. It is responsible for transporting the heat medium (such as high-temperature water or steam) generated by the heat source to various heat users. The heating network refers to the pipeline system and its transport equipment that delivers the heat medium from the heat source to each heat user. It constitutes the core component of the centralized heating system, ensuring the efficient transmission and distribution of heat energy. Through underground pipeline systems, heat energy generated by heat source stations (such as boiler rooms, thermal power plants, etc.) is transported to various buildings or user terminals to meet heating and hot water supply needs. The heating network of a simple direct-connection heating system consists of a pipeline system that transports and distributes the heat medium from the heat source to each heat user. In large-scale centralized heating systems, the heating network consists of a primary network, a secondary network, and pipeline systems distributing heat to each heat user, as well as relay pump stations, secondary heat exchange stations, mixing pump stations, etc.
[0003] In the process of using heating pipe networks, it is necessary to connect the pipes to form a network. However, the existing heating pipes are usually installed by workers, but the pipe joints are relatively complex, which reduces the speed of installation and connection and affects the performance. Based on this, a heating pipe connection structure is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a heating pipeline connection structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating pipe connection structure, comprising a first pipe, a second pipe, and a clamp. An inner gasket is movably fitted inside the first pipe, and guide rings are fixedly installed at both ends of the inner gasket. A first ring is fixedly installed at one end of the first pipe, and several first grooves are formed on the side of the first ring away from the first pipe. A second ring is fixedly installed at one end of the second pipe, and several second grooves are formed on the side of the second ring away from the second pipe. An elastic telescopic column is fixedly installed at one end inside each of the second grooves, and an insertion post is fixedly installed at the telescopic end of the elastic telescopic column. Several... The device has a dry groove, and sealing grooves are provided at the opposite ends of the first and second rings. A sealing gasket is movably installed inside the sealing groove. A sealing ring is fixedly sleeved on the outside of the inner gasket tube. Threaded strips are fixedly installed on the outside of both the first and second rings. Several bolt holes are provided inside the first and second rings. A hinge is fixedly installed at the connection of the clamp. An installation plate is fixedly installed at the end of the clamp away from the hinge. Several fastening bolts are movably inserted into the interior of the installation plate. A rubber plate is movably installed on the opposite side of the installation plate. A threaded groove is provided on the inner side of the clamp. Silicone rings are movably sleeved on the inner sides of both ends of the clamp.
[0006] Preferably, the dimensions of the first tube, the first ring, the second tube, and the second ring are all compatible, and the dimensions of the inner tube are compatible with the dimensions of the first tube and the second tube.
[0007] Preferably, the first and second slots are circumferentially distributed inside the first and second rings, respectively, and the dimensions of the first and second slots are compatible. The first and second slots are circumferentially staggered with the bolt holes.
[0008] Preferably, the grooves are linearly and evenly distributed on the outer side of the insert, the dimensions of the insert are adapted to the dimensions of the first groove, and the dimensions of the sealing ring are adapted to the dimensions of the sealing gasket.
[0009] Preferably, the fastening bolts move through the mounting plate and the rubber plate and extend to the outside of the mounting plate.
[0010] Preferably, the dimensions of the threaded strip are adapted to the dimensions of the threaded groove, and the dimensions of the clamp are adapted to the dimensions of the first ring and the second ring.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this structure, the user first connects the first pipe and the second pipe, inserts the inner gasket into the immovable first pipe or the second pipe, and applies the sealing rings to one side of the pipe respectively, so that the insert pin aligns with the inside of the second slot. After the position is aligned, the first pipe or the second pipe is pushed closer together, so that the insert pin aligns with the inside of the second slot. Then, the bolt is inserted through the bolt hole and tightened, so that the first pipe and the second pipe are firmly connected, and the sealing gasket and sealing ring are compressed and compacted. Then, the clamp is opened and fitted onto the outside of the first ring and the second ring. Then, the fastening bolt is inserted into the mounting plate and the rubber plate and tightened, thereby causing the clamp to shrink and tightly connect the threaded groove to the outside of the threaded strip, which is convenient for stabilization, reduces leakage, increases the tightness of installation, and at the same time, the connection is quick and the installation is stable.
[0012] By using clamps, when the clamps are fitted onto the outside of the first and second rings, the threaded strip and the threaded groove can be aligned through clamping. The elastic deformation of the silicone ring is used to seal and stabilize the position. Alternatively, by fitting the clamps onto the outside of the first and second rings, the threaded strip and the threaded groove are aligned at one end. The connection is then made by rotating the clamps. This method facilitates the installation of smaller pipes, increases the overall connection tightness, reduces loosening, and increases the installation speed. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-4 This utility model provides a technical solution: a heating pipe connection structure, including a first pipe 1, a second pipe 3, and a clamp 16. An inner gasket 7 is movably fitted inside the first pipe 1, and guide rings 23 are fixedly installed at both ends of the inner gasket 7. A first ring 2 is fixedly installed at one end of the first pipe 1, and several first grooves 8 are formed on the side of the first ring 2 away from the first pipe 1. A second ring 4 is fixedly installed at one end of the second pipe 3, and several second grooves 9 are formed on the side of the second ring 4 away from the second pipe 3. An elastic telescopic post 10 is fixedly installed at one end inside the second groove 9, and an insertion post 11 is fixedly installed at the telescopic end of the elastic telescopic post 10. Several grooves 12 are formed on the outer side of the insertion post 11. The first ring 2... Sealing grooves 15 are provided at the opposite ends of the first ring 2 and the second ring 4. A sealing gasket 14 is movably installed inside the sealing groove 15. A sealing ring 13 is fixedly sleeved on the outside of the inner gasket tube 7. Threaded strips 5 are fixedly installed on the outside of the first ring 2 and the second ring 4. Several bolt holes 6 are provided inside the first ring 2 and the second ring 4. A hinge 21 is fixedly installed at the connection of the clamp 16. An installation plate 18 is fixedly installed at the end of the clamp 16 away from the hinge 21. Several fastening bolts 22 are movably inserted into the inside of the installation plate 18. A rubber plate 19 is movably installed on the opposite side of the installation plate 18. A threaded groove 20 is provided on the inside of the clamp 16. Silicone rings 17 are movably sleeved on the inside of both ends of the clamp 16.
[0020] The working principle of the above technical solution is as follows: In use, the user first connects the first pipe 1 and the second pipe 3, inserts the inner gasket 7 into the stationary first pipe 1 or the second pipe 3, and applies the sealing ring 13 to one side of the pipe respectively, so that the insert 11 aligns with the inside of the second slot 9. After the position is aligned, the user pushes the first pipe 1 or the second pipe 3 closer together, so that the insert 11 aligns with the inside of the second slot 9. Then, the user inserts the bolt through the bolt hole 6 and tightens it, so that the first pipe 1 and the second pipe 3 are firmly connected, and the sealing gasket 14 and the sealing ring 13 are compressed and compacted. Then, the clamp 16 is opened and fitted onto the outside of the first ring 2 and the second ring 4. Then, the user inserts the fastening bolt 22 into the mounting plate 18 and the rubber plate 19 and tightens it, so that the clamp 16 contracts, tightly connecting the threaded groove 20 to the outside of the threaded strip 5, which facilitates stability, reduces leakage, increases the tightness of the installation, and at the same time, the connection is quick and the installation is stable.
[0021] In another implementation scheme, such as Figures 1-4 As shown, the specifications and dimensions of the first tube 1, the first ring 2, the second tube 3, and the second ring 4 are all compatible, and the specifications and dimensions of the inner pad tube 7 are compatible with those of the first tube 1 and the second tube 3.
[0022] The first pipe 1, the first ring 2, the second pipe 3, and the second ring 4 are all the same size, which facilitates the connection of pipes of the same size. Products of different specifications cannot be connected. For traditional pipe modification, the first ring 2 and the second ring 4 can be welded and installed on the corresponding pipes, which is convenient for installation and connection. The inner pad pipe 7 provides flow guidance and limit for the middle part, which makes the water flow stable, reduces the scouring of impurities at the connection, and further increases the tightness of the connection and improves the use effect.
[0023] In another implementation scheme, such as Figures 1-4 As shown, the first slot 8 and the second slot 9 are both distributed in a circular pattern inside the first ring 2 and the second ring 4 respectively. The specifications and dimensions of the first slot 8 and the second slot 9 are compatible. The first slot 8 and the second slot 9 are distributed in a circular pattern with the bolt hole 6.
[0024] The correspondence between the first slot 8 and the second slot 9 ensures that the first ring 2 and the second ring 4 do not rotate after docking, facilitating insertion into the corresponding positions. Similarly, the elastic telescopic column 10 can be replaced by inserting the corresponding pin inside the first slot 8 and the second slot 9 for corresponding installation, facilitating the corresponding positions and reducing deflection.
[0025] In another implementation scheme, such as Figure 2 and Figure 3 As shown, the grooves 12 are linearly and evenly distributed on the outside of the insert 11. The dimensions of the insert 11 are adapted to the dimensions of the first hole groove 8, and the dimensions of the sealing ring 13 are adapted to the dimensions of the sealing gasket 14.
[0026] The groove 12 is used to place glue, sealing rings or lubricating oil for connection according to different installation needs. For example, when the elastic telescopic column 10 is replaced by a pin, the insertion column 11 is a pin and the first hole groove 8 and the second hole groove 9 are of equal length. Applying glue to the groove 12 can increase the connection stability of the insertion column 11 and make the structure stable. In addition, applying lubricating oil makes it easy to insert and remove for maintenance and to cope with the effects of different solutions.
[0027] In another implementation scheme, such as Figure 3 As shown, the fastening bolt 22 moves through the mounting plate 18 and the rubber plate 19 and extends to the outside of the mounting plate 18.
[0028] The fastening bolt 22 passes through the mounting plate 18 and the rubber plate 19. When the fastening bolt 22 is tightened and the mounting plate 18 is brought closer together, the rubber plate 19 is compressed, providing a seal and a certain elasticity. This provides an auxiliary effect for tightening the fastening bolt 22, increases the buffering effect of tightening, and increases the tightness of the connection.
[0029] In another implementation scheme, such as Figures 1-4 As shown, the dimensions of the threaded bar 5 are compatible with the dimensions of the threaded groove 20, and the dimensions of the clamp 16 are compatible with the dimensions of the first ring 2 and the second ring 4.
[0030] With the clamp 16, when it is fitted onto the outside of the first ring 2 and the second ring 4, the threaded strip 5 and the threaded groove 20 can be aligned by clamping. The elastic deformation of the silicone ring 17 can be used to seal and stabilize the position. Alternatively, by fitting the clamp 16 onto the outside of the first ring 2 and the second ring 4, the threaded strip 5 and the threaded groove 20 can be aligned at one end. The connection can then be made by rotating the clamp 16. This facilitates the installation of smaller pipes, increases the overall connection tightness, reduces loosening, and increases the installation speed.
[0031] 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.
