Description

Technical Field

[0001] This utility model relates to the technical field of DC thrustless sleeve compensators, specifically a DC thrustless sleeve compensator for preventing excessive displacement. Background Technology

[0002] Expansion joints, also commonly called compensators or expansion joints, consist of a bellows (an elastic element) that forms the main working part, and accessories such as end pipes, supports, flanges, and conduits. Expansion joints are flexible structures installed on container shells or pipelines to compensate for additional stress caused by temperature differences and mechanical vibrations. Utilizing the effective expansion and contraction deformation of its main working body, the corrugated pipe, it absorbs dimensional changes in pipelines, ducts, and containers caused by thermal expansion and contraction, or compensates for axial, lateral, and angular displacements of pipelines, ducts, and containers. It can also be used for noise reduction, vibration damping, and heating. To prevent pipeline deformation or damage caused by thermal expansion or temperature stress when heating pipelines heat up, compensators need to be installed on the pipeline to compensate for the thermal expansion of the pipeline, thereby reducing the stress on the pipe wall and the force acting on valves or support structures. Existing compensators are mostly inner tube sleeves outer tube structures, lacking a medium pressure balance structure. When a corresponding force is generated due to temperature changes, the inner tube can provide a good compensation response; however, when there is a large medium pressure inside the inner tube, due to the lack of medium pressure balance compensation, the inner tube is prone to large axial displacement, which will affect the safe operation and service life of the sleeve compensator. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a DC thrustless sleeve compensator to prevent excessive displacement. This solves the problem mentioned in the background art where, when there is a large medium pressure inside the inner tube, the lack of medium pressure balance compensation can easily cause large axial displacement of the inner tube, which will affect the safe operation and service life of the sleeve compensator.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a DC thrustless sleeve compensator for preventing excessive displacement, comprising an inner tube structure, wherein the outer wall of the inner tube structure is provided with an outer tube structure;

[0005] The inner tube structure includes an inner tube body with a guide sliding groove on the inner side, and the inner tube body slides and matches the inner ring disc through the guide sliding groove and the guide slider. At the same time, a conveying connection pipe with a sealing ring is fixedly installed on one side of the inner ring disc.

[0006] An installation plate is fixedly installed through the outer wall of the inner tube, and a through-hole block is fixedly installed on the surface of the installation plate.

[0007] By adopting the above technical solution, the conveying connecting pipe can achieve force compression and sliding adjustment.

[0008] Preferably, the outer tube structure includes an outer tube body with a connecting plate fixed at one end, and a flange pipe fixedly installed at one end of the connecting plate, while an elastic corrugated pipe that is in communication with the flange pipe is fixedly installed on the other side of the connecting plate.

[0009] By adopting the above technical solution, the outer tube body is used to wrap and fix the installation.

[0010] Preferably, another through-hole block is fixedly installed on the connecting plate, and the other through-hole block is installed and connected to the through-hole block through the connecting bolt group, and the outer tube body wraps around the inner tube body for installation and connection.

[0011] By adopting the above technical solution, a fixed installation can be achieved through the connection plate.

[0012] Preferably, the guide slide grooves are arranged in a circular array.

[0013] By adopting the above technical solution, the guide slide groove is opened to guide the slide.

[0014] Preferably, there are two sets of through-hole blocks, and the through-hole blocks are symmetrically arranged about the axis of the mounting plate.

[0015] By adopting the above technical solution, the through-hole block is used to achieve a through-connection.

[0016] Preferably, one set of elastic bellows is provided, and the elastic bellows are symmetrically arranged about the inner tube body.

[0017] By adopting the above technical solution, the flexible corrugated pipe is used to connect the two ends.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this anti-excessive displacement DC thrustless sleeve compensator,

[0019] (1) This case solves the problem of large axial displacement of the inner tube due to lack of medium pressure balance compensation when there is a large medium pressure inside the inner tube. This is achieved by setting the inner ring disc, conveying connection pipe and elastic bellows in the inner tube structure and outer tube structure. This will affect the safe operation and service life of the sleeve compensator. When the medium pressure inside the inner tube is large, it will push the inner ring disc and conveying connection pipe to squeeze the elastic bellows synchronously. When the medium pressure is balanced by the inner ring disc, conveying connection pipe and elastic bellows, the axial displacement of the inner tube is small, thus avoiding the above problems.

[0020] (2) By setting the inner tube structure and the outer tube structure, not only are the above problems solved, but the guide sliding groove and guide slider opened and set in the inner tube structure are used to ensure the stable positioning and force guidance sliding adjustment of the inner ring plate. Furthermore, by setting the conveying connection pipe with the sealing ring, the leakage of liquid or other objects is avoided. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a DC thrustless sleeve compensator to prevent excessive displacement, such as... Figure 1 , Figure 2 and Figure 3As shown, it includes an inner tube structure 1, which includes an inner tube body 101 with guide sliding grooves 102 on its inner side. The guide sliding grooves 102 are arranged in a ring array. This ring array arrangement not only enhances the aesthetics of the structure but also demonstrates axial and longitudinal symmetry. Furthermore, it provides adjustable guiding and sliding capabilities. The inner tube body 101 slides and engages with the inner ring disc 104 via the guide sliding grooves 102 and guide sliders 103. A conveying connection pipe 105 with a sealing ring is fixedly installed on one side of the ring disc 104. An installation disc 106 is fixedly installed through the outer wall of the inner pipe body 101, and a through hole block 107 is fixedly installed on the surface of the installation disc 106. Two sets of through hole blocks 107 are provided, and the through hole blocks 107 are symmetrically arranged about the axis of the installation disc 106. When the above-mentioned components are provided in two sets of four blocks, it not only reflects the practicality of the above-mentioned component installation, but also reflects the through connection of the above-mentioned component installation. Furthermore, when the above-mentioned components are provided in two sets of four blocks, it reflects the symmetry of the above-mentioned components.

[0028] like Figure 4 As shown, the outer wall of the inner tube structure 1 is provided with an outer tube structure 2. The outer tube structure 2 includes an outer tube body 201 with a connecting plate 202 fixed at one end, and a flange pipe 203 fixedly installed at one end of the connecting plate 202. At the same time, an elastic bellows pipe 204 that is connected to the flange pipe 203 is fixedly installed on the other side of the connecting plate 202. One set of elastic bellows pipes 204 is provided, and the elastic bellows pipes 204 are symmetrically arranged about the inner tube body 101. When the above-mentioned components are provided in a set of two, this not only reflects the fixed installation at both ends of the above-mentioned components, but also reflects the through-conveying and conveying properties of the above-mentioned components, thereby reflecting the practicality of the connection and conveying of the above-mentioned components. When the component is provided with a set of two, it simultaneously demonstrates the stress compression and elastic recovery adjustment effects of the aforementioned component. Another through-hole block 107 is fixedly installed on the connecting plate 202, and the other through-hole block 107 is installed and connected to the connecting bolt group 205. The outer tube body 201 is installed and connected to the inner tube body 101. The flange tube 203 is provided to facilitate the installation, connection and disassembly of the flange tube 203 with the external pipeline. The sealing ring of the conveying connecting pipe 105 ensures the sealing of the inner tube body 101 and prevents liquid leakage due to poor sealing of the inner tube body 101 when the conveying connecting pipe 105 is adjusted under force.

[0029] In the above scheme, after the operator connects to the external pipeline through the flange pipe 203, the external medium is transported into the inner pipe body 101 through the flange pipe 203 and the elastic bellows pipe 204. When the pressure of the medium transported inside the inner pipe body 101 is high, it pushes the inner ring plate 104 and the conveying connection pipe 105 to squeeze the elastic bellows pipe 204 simultaneously. When the pressure of the medium is compensated and balanced by the inner ring plate 104, the conveying connection pipe 105 and the elastic bellows pipe 204, the displacement of the inner axis of the inner pipe body 101 is small.
