Description

Technical Field

[0001] The utility model relates to the technical field of non-metal compensators, in particular to a non-metal compensator with an anti-leakage structure. Background Art

[0002] In modern industrial production, many piping systems are subject to stresses caused by temperature changes, vibrations or installation errors. In order to reduce the rigid impact of these stresses on the system, non-metallic compensators are usually used as flexible connections to absorb displacement, reduce noise and prevent pipeline damage.

[0003] The existing patent (publication number: CN212361213U) proposes a non-metallic compensator. The compensator body is composed of a ring body and a compensation component. The two ring bodies are connected by a skin, and the skin wraps the space between the two ring bodies. The two ends of the skin are bent and attached to the side of the ring body and pressed tightly with an annular pressure plate. Finally, they are fixed with a number of bolt assemblies to connect the two ring bodies and the skin into a whole. Several ear plates with through holes are evenly distributed on the outer circumference of the pressure plates on both sides.

[0004] This utility model can compensate for multi-dimensional directions, effectively compensate for and eliminate installation errors and displacement errors, has a wide applicable temperature range, good corrosion resistance, and effectively isolates vibrations and reduces noise. However, in actual use, the following deficiencies still exist, such as: existing non-metallic compensators cannot solve the problem of leak prevention at the connection between the compensator and the pipeline. Leakage will cause the loss of medium in the system, thereby affecting the working efficiency of the system. Leakage of the medium may cause pollution to the surrounding environment, especially the leakage of harmful or dangerous media. Leakage is often accompanied by wear and corrosion of components, which will shorten the service life of the equipment. Therefore, this utility model proposes a non-metallic compensator with a leak-proof structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a non-metallic compensator with an anti-leakage structure.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a non-metallic compensator with an anti-leakage structure, comprising a non-metallic compensator body, an anti-leakage component is provided on the non-metallic compensator body, and an elastic component is provided in the non-metallic compensator body; the anti-leakage component comprises a fixed block, a rotating shaft is rotatably connected to the fixed block, a sealing plate is fixed on the rotating shaft, a rubber pad is fixed on the side of the sealing plate close to the fixed block, a first fixed seat is fixed on the fixed block, a second fixed seat is fixed on the sealing plate, and a limiting groove is provided in the fixed block.

[0007] As a preferred embodiment, the fixing block is fixed on the non-metallic compensator body, and a limiting ring is fixed on the non-metallic compensator body.

[0008] The beneficial effect of adopting the above-mentioned further scheme is: since the fixing block is fixed on the non-metallic compensator body, the anti-leakage component as a whole can be supported and fixed on the non-metallic compensator body; since the limiting ring is fixed on the non-metallic compensator body, the sealing effect between the pipeline and the non-metallic compensator body can be enhanced after the limiting ring is inserted into the pipeline.

[0009] As a preferred embodiment, a bolt is threadedly connected to the second fixing seat, and the bottom of the bolt is threadedly connected to the first fixing seat.

[0010] The beneficial effect of adopting the above further solution is: since the second fixing seat is threaded with a bolt, and the bottom of the bolt is threadedly connected to the first fixing seat, the bolt can fix the first fixing seat and the second fixing seat, thereby enabling the sealing plate to be fixed to the fixing block.

[0011] As a preferred embodiment, the elastic component includes a support plate, the support plate is fixed on the non-metallic compensator body, and an annular spring is fixed on the support plate.

[0012] The beneficial effect of adopting the above further scheme is that when the temperature inside the non-metallic compensator body exceeds a certain range, the compensator will lose its elasticity, harden or break due to overheating. The annular spring fixed on the support plate can continue to provide elastic effect after the non-metallic compensator body loses its elasticity.

[0013] As a preferred embodiment, a first limiting block is fixed on a side of the support plate close to the annular spring.

[0014] The beneficial effect of adopting the above further solution is that since the first limit block is fixed on the side of the support plate close to the annular spring, the first limit block can support and limit the limit rod and the second limit block.

[0015] As a preferred embodiment, a limiting rod is slidably connected to the first limiting block, and a second limiting block is fixed to the limiting rod.

[0016] The beneficial effect of adopting the above further solution is that through the cooperation of the first limit block, the limit rod and the second limit block, the limit rod can limit the elastic expansion and contraction of the annular spring and prevent the annular spring from deflecting.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are: in the present invention, the operator inserts the pipe on which the non-metallic compensator needs to be installed into the limiting groove opened on the fixed block, inserts the limiting ring into the pipe, rotates the sealing plate so that the first fixing seat and the second fixing seat can be aligned, screws the bolt thread into the first fixing seat and the second fixing seat so that the sealing plate can be fixed on the fixed block, and after the flange on the pipe is fixed to the flange of the non-metallic compensator, the rubber pad is provided so that the pipe mouth and the flange can be sealed to the fixed block, thereby solving the technical problem of liquid or gas leakage at the connection between the pipe and the non-metallic compensator.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1-4 As shown, this embodiment provides a technical solution: a non-metallic compensator with an anti-leakage structure, comprising a non-metallic compensator body 1, an anti-leakage component 2 is provided on the non-metallic compensator body 1, and an elastic component 3 is provided in the non-metallic compensator body 1.

[0025] like Figure 1-Figure 3 As shown, the leakage prevention assembly 2 includes a fixed block 21, a rotating shaft 23 is rotatably connected to the fixed block 21, a sealing plate 24 is fixed to the rotating shaft 23, a rubber pad 25 is fixed to the side of the sealing plate 24 close to the fixed block 21, a first fixing seat 26 is fixed to the fixed block 21, and a second fixing seat 27 is fixed to the sealing plate 24. A limiting groove 29 is provided in the fixed block 21. When installing the non-metallic compensator, the operator first inserts the pipe into the limiting groove 29 on the fixed block 21 to ensure that the pipe is in the correct position, and then inserts the limiting ring 22 into the pipe to perform Stabilize the pipeline in one step, then rotate the sealing plate 24 to align the first fixing seat 26 with the second fixing seat 27, and then screw the bolt 28 into the two fixing seats to firmly fix the sealing plate 24 on the fixing block 21. After completing these steps, the flange on the pipeline and the flange of the non-metallic compensator are fixed. The rubber gasket 25 is set to effectively seal the pipeline mouth and the flange and fix it in the fixing block 21, thereby improving the safety and reliability of the system, thereby solving the technical problem of liquid or gas leakage at the connection between the pipeline and the non-metallic compensator.

[0026] The above solution also has the problem that when the temperature inside the non-metal compensator body 1 exceeds a certain range, it cannot continue to provide the elastic effect, such as Figure 1-Figure 3 As shown: the fixed block 21 is fixed on the non-metallic compensator body 1, and the limiting ring 22 is fixed on the non-metallic compensator body 1. Since the fixed block 21 is fixed on the non-metallic compensator body 1, the anti-leakage component 2 as a whole can be supported and fixed on the non-metallic compensator body 1. Since the limiting ring 22 is fixed on the non-metallic compensator body 1, the limiting ring 22 can enhance the sealing effect between the pipeline and the non-metallic compensator body 1 after being inserted into the pipeline. The second fixing seat 27 is threadedly connected with a bolt 28, and the bottom of the bolt 28 is threadedly connected to the first fixing seat 26. Since the second fixing seat 27 is threadedly connected with the bolt 28, and the bottom of the bolt 28 is threadedly connected to the first fixing seat 26, the bolt 28 can fix the first fixing seat 26 and the second fixing seat 27, so that the sealing plate 24 can be fixed on the fixed block 21.

[0027] like Figure 3As shown, the elastic component 3 includes a support plate 31, which is fixed on the non-metallic compensator body 1, and a ring spring 32 is fixed on the support plate 31. When the temperature inside the non-metallic compensator body 1 exceeds a certain range, the compensator will lose its elasticity, harden or break due to overheating. The ring spring 32 fixed on the support plate 31 can continue to provide an elastic effect after the non-metallic compensator body 1 loses its elasticity. A first limit block 33 is fixed on the side of the support plate 31 close to the ring spring 32. Since the first limit block 33 is fixed on the side of the support plate 31 close to the ring spring 32, the first limit block 33 can support and limit the limit rod 34 and the second limit block 35. The first limit block 33 is slidably connected to the limit rod 34, and the second limit block 35 is fixed on the limit rod 34. Through the cooperation of the first limit block 33, the limit rod 34 and the second limit block 35, the limit rod 34 can limit the elastic expansion and contraction of the ring spring 32 to prevent the ring spring 32 from deflecting.

[0028] Working principle: Figures 1-4 As shown, when installing the non-metallic compensator, the operator first inserts the pipe into the limiting groove 29 on the fixing block 21 to ensure that the pipe is accurately positioned. Then, the limiting ring 22 is inserted into the pipe to further stabilize the pipe. Then, the sealing plate 24 is rotated to align the first fixing seat 26 with the second fixing seat 27, and then the bolt 28 is screwed into the two fixing seats to firmly fix the sealing plate 24 on the fixing block 21. After completing these steps, the flange on the pipe and the flange of the non-metallic compensator are fixed, and the pipe opening can be effectively sealed by the provided rubber pad 25. With the flange, it is fixed in the fixed block 21, which improves the safety and reliability of the system. When the temperature in the non-metallic compensator body 1 exceeds a certain range, the compensator will lose its elasticity, harden or break due to overheating. The annular spring 32 fixed on the support plate 31 can continue to provide elastic effect after the non-metallic compensator body 1 loses its elasticity. Through the cooperation of the first limit block 33, the limit rod 34 and the second limit block 35, the limit rod 34 can limit the elastic expansion and contraction of the annular spring 32 to prevent the annular spring 32 from deflecting.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
