Description

Technical Field

[0001] The utility model belongs to the technical field of compensator joints, and particularly relates to a compensator joint for preventing water leakage. Background Technique

[0002] The chemical compensator joint is a pipeline connection component widely used in the chemical industry. It is mainly used to compensate for the displacement changes of pipelines caused by thermal expansion and contraction or other factors, effectively absorb pipeline deformation, prevent pipelines from being damaged due to stress concentration. The compensator joint mainly consists of a compensator, a connecting piece and a sealing piece. The sealing piece is mainly responsible for the sealing of the connection between the compensator joint and the pipeline, and can avoid water leakage. As the main stress-bearing component, the corrugated pipe has a large elastic deformation ability. The compensator joint can operate stably under various temperature, pressure and medium conditions, improving the safety and reliability of the pipeline system. The chemical compensator joint plays an important role in the chemical industry and provides a strong guarantee for the stable operation of the pipeline system.

[0003] Chinese Patent with the publication number of "CN214064148U" discloses a metal hose compensator joint device, including a compensator body, a pipeline and a joint pipe body. One end of the compensator body is installed with a joint pipe body, and one end of the joint pipe body is installed with a pipeline. The utility model relates to the technical field of pipelines. This metal hose compensator joint device solves the problems that the existing compensator and joint are integrally arranged, so that if one of them is damaged, both must be replaced, the cost is high, and the disassembly and assembly between the joint and the pipeline are inconvenient and the sealing performance is not good. By setting an external thread cap, an internal thread pipe, a fixing ring and a second thread groove, it is convenient to install and disassemble the joint pipe body with the compensator body and the pipeline.

[0004] However, there are still some deficiencies in this joint. Although connecting the compensator joint and the pipe body through threaded parts is beneficial to the later disassembly and assembly, the threaded connection still has certain defects. Because the compensator joint and the pipe body sometimes shake due to external influence, under the long-term threaded fixation, the shaking frequency will loosen the connection points of the threaded connectors, which will affect the stability of the fixation between the compensator joint and the pipe body. Summary of the Utility Model

[0005] Aiming at the problems mentioned in the background technique, the purpose of the utility model is to provide a compensator joint for preventing water leakage to solve the problems raised in the above background technique.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A leak-proof compensator joint, comprising a compensator joint body. One side of the compensator joint body is threadedly connected to a pipe body. A connecting plate is threadedly connected to the outer wall of the pipe body. One side of the connecting plate is fixedly connected to a connecting frame. External threads are provided on the outer wall of the connecting frame. Thread grooves matching the external threads are provided on the other side of the compensator joint body. The connecting frame is threadedly connected to the inside of the thread groove through the external threads. The pipe body is threadedly connected to one side of the compensator body through the connecting frame. A bayonet is provided on one side of the connecting plate. A clamping block is clamped inside the bayonet. A clamping groove matching the clamping block is provided on the other side of the compensator body. The position of the clamping groove is symmetrical to the position of the clamping block. A convex block is fixedly connected to the other side of the clamping block. A first sealing ring is fixedly connected to one side of the connecting plate. A second sealing ring matching the first sealing ring is fixedly connected to the other side of the compensator joint body. The positions of the first sealing ring and the second sealing ring are symmetrical. When in use, first rotate the pipe body through the thread principle. The pipe body can drive the connecting frame to rotate together. The connecting frame can be screwed into the thread groove through the external threads, so as to effectively limit and fix the position of the pipe body. When the pipe body is fixed, the first sealing ring and the second sealing ring will be attached to each other, thereby being able to prevent water from flowing out through the connection point between the two. Subsequently, the user can snap the clamping block into the symmetrical clamping groove through the clamping principle. The clamping block can perform secondary limiting on the fixed position of the connecting plate.

[0008] As a preferred technical solution, an anti-corrosion layer is coated on the outer wall of the compensator joint body. The thickness of the anti-corrosion layer is one centimeter. The anti-corrosion layer covers the outer wall of the compensator joint body. By applying the anti-corrosion layer, the corrosion resistance of the compensator joint body can be effectively improved, thereby increasing the service life of the compensator joint body.

[0009] As a preferred technical solution, a heat-resistant layer is coated on the inner wall of the compensator joint body. The thickness of the heat-resistant layer is one centimeter. The heat-resistant layer covers the inner wall of the compensator joint body. By applying the heat-resistant layer, the heat resistance of the inner wall of the compensator joint body can be effectively improved, and the compensator joint body can be prevented from being damaged due to high temperature.

[0010] As a preferred technical solution, a fixing block is fixedly connected to the other side of the connecting plate. The rear side of the fixing block is attached to the outer wall of the pipe body. A first screw hole is provided on the front side of the fixing block. The first screw hole penetrates through the fixing block and the outer wall of the pipe body. A first bolt is threadedly connected to the inside of the first screw hole. The rear side of the first bolt is threadedly connected to the inside of the pipe body through the first screw hole. The connecting plate is threadedly connected to the outer wall of the pipe body through the fixing block, the first screw hole and the first bolt. By screwing in the first bolt, the position of the connecting plate can be effectively fixed, and the connecting plate can be prevented from shifting. When the connecting plate needs to be disassembled, unscrew the first bolt from the first screw hole.

[0011] As a preferred technical solution, a rotating shaft is rotatably connected to one side of the pipe body. A filter plate is threadedly connected to one side of the rotating shaft. The filter plate covers the inner side of the compensator joint body. The outer wall of the filter plate is slidably connected to the inner wall of the compensator joint body. By installing the filter plate, the filter plate can effectively filter the water source flowing inside the pipe body and the compensator joint body, thereby filtering out a large amount of mixtures in the water source. The rotating shaft enables the pipe body to rotate normally, thus not interfering with the normal connection of the pipe body.

[0012] As a preferred technical solution, a chute matching the filter plate is provided on the inner wall of the compensator joint body. The filter plate is slidably connected to the inner wall of the compensator joint body through the chute. By providing the chute, the position and angle of movement of the filter plate can be effectively limited, thereby improving the stability of the position adjustment of the filter plate.

[0013] As a preferred technical solution, a second screw hole is provided on one side of the filter plate. The second screw hole penetrates through one side of the filter plate and the rotating shaft. A second bolt is threadedly connected to the inner side of the second screw hole. The other side of the second bolt is threadedly connected to the inside of the rotating shaft through the second screw hole. The filter plate is threadedly connected to one side of the rotating shaft through the second screw hole and the second bolt. By screwing in the second bolt, the position of the filter plate can be effectively fixed, and the situation of the filter plate falling off can be avoided. When the filter plate needs to be disassembled, unscrew the second bolt from the second screw hole.

[0014] In summary, the present utility model mainly has the following beneficial effects:

[0015] First, during use, first rotate the pipe body through the thread principle. The connecting frame can be screwed into the thread groove through the external thread, thereby effectively limiting and fixing the position of the pipe body. When the pipe body is fixed, the first sealing ring and the second sealing ring will be in contact with each other, thereby preventing the water source from flowing out through the connection point between the two. Subsequently, the user can snap the block into the symmetrical slot through the snap connection principle. The block can perform secondary limiting on the fixed position of the connecting plate. When the compensator joint body and the pipe body shake, the block can prevent the fixed point of the connecting frame from loosening, thereby preventing the stability of the connection between the compensator joint body and the pipe body from being reduced.

[0016] Second, due to the presence of the filter plate, the filter plate can effectively filter the water source flowing between the compensator joint body and the pipe body, thereby blocking the mixtures flowing in the water source. The provision of the chute is conducive to effectively limiting the moving position of the filter plate, thereby improving the stability of the position movement of the filter plate. When it is necessary to clean the mixtures blocked by the filter plate, first disassemble the pipe body, and then directly pull out the filter plate through the chute. The filter plate can bring out the blocked mixtures together, thereby effectively improving the quality of the water source itself. Description of the Drawings

[0023] Embodiment

[0024] Refer to Figures 1 to 5, A leak-proof compensator joint in this embodiment includes a compensator joint body 1. One side of the compensator joint body 1 is threadedly connected to a pipe body 2. A connecting plate 5 is threadedly connected to the outer wall of the pipe body 2. One side of the connecting plate 5 is fixedly connected to a connecting frame 9. An external thread 10 is provided on the outer wall of the connecting frame 9. A thread groove 16 matching the external thread 10 is provided on the other side of the compensator joint body 1. The connecting frame 9 is threadedly connected to the inside of the thread groove 16 through the external thread 10. The pipe body 2 is threadedly connected to one side of the compensator body through the connecting frame 9. A bayonet 12 is provided on one side of the connecting plate 5. A clamping block 13 is clamped inside the bayonet 12. A clamping groove 17 matching the clamping block 13 is provided on the other side of the compensator body. The position of the clamping groove 17 is symmetrical to the position of the clamping block 13. A convex block 14 is fixedly connected to the other side of the clamping block 13. A first sealing ring 11 is fixedly connected to one side of the connecting plate 5. A second sealing ring 15 matching the first sealing ring 11 is fixedly connected to the other side of the compensator joint body 1. The position of the first sealing ring 11 is symmetrical to the position of the second sealing ring 15. The compensator joint for chemical industry has multiple important uses in the chemical industry field. Due to reasons such as temperature changes and medium flow in chemical pipelines, thermal expansion, contraction and vibration will occur. The compensator joint can effectively absorb and relieve these stresses, reduce the impact on pipelines and equipment, protect the safety and stability of the pipeline system. Due to construction errors, earthquakes and other reasons, the pipeline may be displaced. The compensator joint can compensate for the displacement of the pipeline within a certain range, maintain the connectivity and sealing performance of the pipeline, and ensure the normal operation of the pipeline system. When the medium flows in the pipeline, vibration and noise will be generated. The compensator joint has good shock absorption and noise reduction effects, and can effectively reduce the vibration and noise of the pipeline system, improving the comfort of the working environment. By absorbing pipeline stress and compensating for pipeline displacement, the compensator joint can reduce the stress concentration at the pipeline connection point, prevent the pipeline from being damaged due to excessive stress at the pipeline connection point, and thus extend the service life of the pipeline. The compensator joint can adjust the pressure of the pipeline according to the needs of the pipeline system, maintain the balance and stability of the pipeline system, and ensure the smooth progress of chemical production.

The anti-corrosion layer 3 covers the outer wall of the compensator joint body 1. The anti-corrosion layer 3 is an anti-corrosion coating, which can form a covering layer on the surface of the compensator joint body 1 to isolate the base material from the surrounding corrosive medium, so as to achieve the purpose of preventing corrosion and extending the service life.

[0026] Reference Figure 1, a heat-resistant layer 4 is coated on the inner wall of the compensator joint body 1. The thickness of the heat-resistant layer 4 is one centimeter. The heat-resistant layer 4 covers the inner wall of the compensator joint body 1.

The rear side of the first bolt 8 is threadedly connected to the inside of the pipe body 2 through the first screw hole 7. The connecting plate 5 is threadedly connected to the outer wall of the pipe body 2 through the fixing block 6, the first screw hole 7 and the first bolt 8. Due to the existence of the first bolt 8, when the first bolt 8 is screwed in, the position of the connecting plate 5 can be effectively fixed, and the displacement of the connecting plate 5 can be avoided. When the connecting plate 5 needs to be disassembled, the first bolt 8 is screwed out of the first screw hole 7, which is also beneficial for the user to disassemble, assemble and maintain the connecting plate 5 individually later.

[0028] Reference Figure 4 And Figure 5 , one side of the pipe body 2 is rotatably connected with a rotating shaft 19. A filter plate 18 is threadedly connected to one side of the rotating shaft 19. The filter plate 18 covers the inside of the compensator joint body 1. The outer wall of the filter plate 18 is slidably connected to the inner wall of the compensator joint body 1. A sliding groove 22 matching the filter plate 18 is opened on the inner wall of the compensator joint body 1. The filter plate 18 is slidably connected to the inner wall of the compensator joint body 1 through the sliding groove 22. Due to the existence of the filter plate 18, the filter plate 18 can effectively filter the water source flowing between the compensator joint body 1 and the pipe body 2, thus blocking the mixture flowing in the water source. The opening of the sliding groove 22 can effectively limit the movement position of the filter plate 18, thus improving the stability of the movement position of the filter plate 18. The rotating shaft 19 can prevent the pipe body 2 from not being able to rotate, thus not affecting the normal installation and disassembly of the pipe body 2. When the mixture blocked by the filter plate 18 needs to be cleaned, first disassemble the pipe body 2, and then directly pull out the filter plate 18 through the sliding groove 22. The filter plate 18 can bring out the blocked mixture together.

Due to the presence of the second bolt 21, the screwing-in of the second bolt 21 can effectively fix the position of the filter plate 18, and can prevent the filter plate 18 from falling off. When it is necessary to disassemble the filter plate 18, just screw out the second bolt 21 from the second screw hole 20. At the same time, it is also beneficial for the user to individually disassemble, assemble and maintain the filter plate 18 in the later stage.

[0030] Principle of use and advantages: When in use, first rotate the pipe body 2 through the screw principle. The connecting frame 9 can be screwed into the thread groove 16 through the external thread 10, so as to effectively limit and fix the position of the pipe body 2.

Subsequently, the user can snap the block 13 into the symmetric slot 17 through the snap connection principle. The block 13 can perform secondary limitation on the fixed position of the connecting plate 5. When the compensator joint body 1 and the pipe body 2 shake, the block 13 can prevent the fixed point of the connecting frame 9 from loosening, thereby avoiding the reduction of the connection stability between the compensator joint body 1 and the pipe body 2. Due to the existence of the anti-corrosion layer 3, the anti-corrosion layer 3 can form a covering layer on the surface of the compensator joint body 1 to isolate the base material from the surrounding corrosive medium, so as to achieve the purpose of preventing corrosion and extending the service life. Due to the existence of the heat-resistant layer 4, the heat-resistant layer 4 is a high-temperature resistant coating, which can effectively improve the high-temperature resistance of the inner wall of the compensator, thereby avoiding the damage of the compensator joint body 1 due to the influence of high temperature. Due to the existence of the first bolt 8, the first bolt 8 can be screwed in to effectively fix the position of the connecting plate 5 and prevent the connecting plate 5 from shifting. When it is necessary to disassemble the connecting plate 5, just unscrew the first bolt 8 from the first screw hole 7, which is also beneficial for the user to disassemble, assemble and maintain the connecting plate 5 individually in the later stage. Due to the existence of the filter plate 18, the filter plate 18 can effectively filter the water flowing between the compensator joint body 1 and the pipe body 2, thereby blocking the mixture flowing in the water. The opening of the sliding groove 22 can effectively limit the movement position of the filter plate 18, thereby improving the stability of the movement position of the filter plate 18. Its rotating shaft 19 can prevent the pipe body 2 from not being able to rotate, and thus will not affect the normal installation and disassembly of the pipe body 2.
