Abstract
Description
Technical Field
[0001] This utility model relates to the field of compensator technology, and in particular to a safe and wear-resistant compensator. Background Technology
[0002] Existing metal compensators are typically manufactured by directly assembling two pipe structures with external flanges and then sealing them with sleeves at the mating points. The mating points are cylindrical spaces sealed with sealing rings. During use, the force at the maximum position of the compensator's movement space is relatively large, which makes it prone to wear and tear, resulting in relatively poor durability, higher costs in the later stages of use, and less convenient maintenance. Utility Model Content
[0003] The purpose of this utility model is to provide a safe and wear-resistant compensator. It features an inclined mating structure on both sides of the sleeve, and a double-sealed connection at both ends, ensuring better sealing at the connection point. The compensator body has a limiting structure that enables double compensation and limiting fit, effectively reducing damage to the flange structure during use and improving overall wear resistance. This structure is also convenient to produce, has relatively low production costs, a longer service life, and higher overall load-bearing capacity during use.
[0004] The technical solution of this utility model is as follows:
[0005] A safe and wear-resistant compensator includes two combined first and second pipeline main structures. A compensator assembly flange seat is provided on the exterior of an adjacent side of the first and second pipeline main structures. The two compensator assembly flange seats are connected together by circumferentially distributed connecting rods. A compensator connecting sealing sleeve is provided on the exterior of the first and second pipeline main structures. The compensator assembly flange seat has a ring of cylindrical compensating limiting fitting columns on the side near the compensator connecting sealing sleeve. The main body of the compensator connecting sealing sleeve is cylindrical. Inclined outward-facing combined sealing stabilizing columns are provided on the left and right sides of the compensator connecting sealing sleeve. The outer side of the combined sealing stabilizing columns is connected to the compensator assembly flange seat. The inner cylindrical surfaces of the compensating limiting fitting column are fitted together. A triangular-section sealing combination safety groove is formed between the combined sealing and stabilizing column and the compensator combined flange seat. A cylindrical safety movable compensating fitting groove is provided inside the compensator connecting sealing sleeve at the splicing position of the first pipeline main structure and the second pipeline main structure. A compensating limiting fitting groove with communication with the interior and evenly distributed around the circumference is provided on the outer cylindrical surface of the adjacent end of the first pipeline main structure and the second pipeline main structure. A main compensating movable limiting bolt is provided on the outside of the compensator connecting sealing sleeve with evenly distributed around the circumference. The interior of the main compensating movable limiting bolt is inserted into the interior of the compensating limiting fitting groove, and the main compensating movable limiting bolt can move within the compensating limiting fitting groove.
[0006] Furthermore, the compensation limiting fitting column and the compensator combined flange seat are integrally formed structures.
[0007] Furthermore, a reinforcing support column is provided at the connection position between the external sealing sleeve of the compensator and the main body compensation movable limit bolt.
[0008] Furthermore, the positions of the compensation limiting grooves provided on the first pipeline main structure and the second pipeline main structure completely overlap in the projection area in the left-right direction.
[0009] Furthermore, the upper end of the combined sealing and stabilizing column is provided with a combined safety sealing ring with an L-shaped cross section at the connection position between the compensation limiting and matching column and the compensator combined flange seat.
[0010] The beneficial effects of this utility model are:
[0011] This utility model adopts a brand-new structural design. By setting an inclined mating structure on both sides of the sleeve, and using a double sealing method for the connection at both ends, better sealing of the connection position is ensured. The compensator body position can achieve double compensation and limiting mating by setting a limiting structure, which can effectively reduce damage to the flange structure during use, and improve the overall wear resistance. This structure is also more convenient to produce, with relatively low production cost, longer service life, and higher overall load-bearing capacity during use. Attached Figure Description

[0021] like Figures 1 to 8As shown, a safety-type wear-resistant compensator includes two combined first pipeline main structures 1 and second pipeline main structures 2. Compensator combination flange seats 3 are provided on the exterior of adjacent sides of the first pipeline main structure 1 and the second pipeline main structure 2. The two compensator combination flange seats 3 are connected together by circumferentially distributed connecting combination rods 4 to form the main structure of the compensator. Compensator connecting sealing sleeves 6 are provided on the exterior of the first pipeline main structure 1 and the second pipeline main structure 2. A ring of cylindrical compensation limiting fitting columns 5 is provided on the side of the compensator combination flange seat 3 near the compensator connecting sealing sleeve 6. The main body of the compensator connecting sealing sleeve 6 is a cylindrical structure. Inclined outward-facing combination sealing stabilizing columns 7 are provided on the left and right sides of the compensator connecting sealing sleeve 6, resulting in stronger bearing capacity at the end positions during assembly and providing more space for the installation of the sealing structure. The outer side of the combination sealing stabilizing column 7 is fitted and fitted together with the inner cylindrical surface of the compensation limiting fitting column 5. The combined sealing and stabilizing column 7 and the compensator combined flange seat 3 form a triangular cross-section sealing combination safety groove 9, which can be combined and connected with the sealing ring to achieve internal sealing fit. The compensator connecting sealing sleeve 6 has a cylindrical safety movable compensation fit groove 8 at the splicing position of the first pipeline main structure 1 and the second pipeline main structure 2, which provides a larger space between this position and the two pipeline main structures, effectively reducing wear during use and improving the overall wear resistance. The outer cylindrical surface of the first pipeline main structure 1 and the second pipeline main structure 2 at adjacent ends is provided with compensation and limiting grooves 10 that are connected to the interior and are evenly distributed around the circumference. The outside of the compensator connecting sealing sleeve 6 is provided with main compensation movable limiting bolts 11 that are evenly distributed around the circumference. The interior of the main compensation movable limiting bolts 11 is inserted into the interior of the compensation and limiting grooves 10. The main compensation movable limiting bolts 11 can move within the compensation and limiting grooves 10. In use, they can limit the movement of the pipeline main structure and form a double limiting function with the external connecting rod. The load-bearing capacity is more guaranteed in use and can meet the safety requirements of application environments with large impact forces. It adopts a brand-new structural design. By setting an inclined mating structure on both sides of the sleeve, the mating positions at both ends are combined and connected in a double-sealing manner, which ensures better sealing at the connection position. The compensator body position can achieve double compensation and limiting mating by setting a limiting structure, which can effectively reduce damage to the flange structure during use, making the overall wear resistance better. This structure is also relatively convenient to produce, with relatively low production costs, longer service life, and higher overall load-bearing capacity during use.
[0022] Preferably, the compensation limiting fitting column 5 and the compensator combination flange seat 3 are integrally formed, which makes the overall structural support strength better and the service life longer during use.
[0023] Preferably, the external connection position of the compensator connecting sealing sleeve 6 and the main body compensation movable limiting bolt 11 is provided with a reinforced support mating column, which has a stronger load-bearing capacity when mating, a stronger anti-cracking ability at the external position, and better overall durability during use.
[0024] Preferably, the positions of the compensation limiting grooves 10 provided on the first pipeline main structure 1 and the second pipeline main structure 2 completely overlap in the projection area in the left and right directions. This results in better balance of their mutual cooperation positions during use, more reliable stability, and further improved wear resistance and stability during use.
[0025] Preferably, the upper end of the combined sealing and stabilizing column 7 is provided with a combined safety sealing ring with an L-shaped cross section at the connection position between the compensation limiting and fitting column 5 and the compensator combined flange seat 3, so as to improve the sealing safety of the fitting position and make the internal safety more reliable during use.
[0026] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
