Description

Technical Field

[0001] This utility model relates to the field of rotary compensator technology, specifically a rotary compensator suitable for high-voltage working environments. Background Technology

[0002] Pipeline compensators typically compensate for pipeline displacement by expanding or rotating a sliding core tube. Sealing packing is used to maintain the pipeline seal and prevent media leakage. However, for pipelines transporting high-temperature and high-pressure media, the unavoidable assembly gaps in pipeline compensators and the relatively low strength of traditional sealing packing, coupled with the effects of high-temperature and high-pressure media, cause significant wear and tear on the sealing packing during the compensator's deflection and displacement. This makes rotary compensators unsuitable for high-pressure working environments. Furthermore, the large clearances between the rotating components of existing rotary compensators, combined with the pipeline thrust, result in poor relative rotation stability between the inner and outer tubes, easily leading to misalignment and eccentric deflection, increasing rotational resistance. In high-pressure pipelines, this makes them prone to wear or damage. After a period of use, the sealing performance of the sealing packing is affected, leading to seal failure and leakage. If not detected and maintained promptly, this can even cause safety accidents. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a rotary compensator suitable for high-pressure working environments. This addresses the issues raised in the background section, such as the unavoidable assembly gaps in pipeline compensators and the low strength of traditional sealing packings. Combined with the effects of high-temperature and high-pressure media, the sealing packings suffer significant wear during the deflection and displacement of the compensator, making the rotary compensator unsuitable for high-pressure working environments. Furthermore, existing rotary compensators have large clearances between rotating components, resulting in poor relative rotation stability of the inner and outer pipes under pipeline thrust, easily leading to misalignment and eccentric deflection, increasing rotational resistance. When used in high-pressure pipelines, these compensators are prone to wear or damage, and after a period of use, the sealing performance of the sealing packings is affected, leading to seal failure and leakage. If not detected and maintained promptly, this can even cause safety accidents.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotary compensator suitable for high-pressure working environments, comprising an outer tube structure, wherein an inner tube structure is provided inside the outer tube structure;

[0005] The outer tube structure includes an outer tube body with a connecting hole, and a connecting ring with a groove is fixedly installed inside the outer tube body. At the same time, a ball bearing for rotation adjustment is provided inside the groove.

[0006] A limiting box is fixedly installed on the surface of the connecting ring, and a first combined filler is placed inside the limiting box.

[0007] By adopting the above technical solution, the connecting ring is used to open and fix the installation.

[0008] Preferably, the inner tube structure includes a rotating inner tube with a matching groove at one end, and the rotating inner tube is connected to the ball bearing through the matching groove. At the same time, a second combined filler material is provided above the surface of the rotating inner tube and is arranged in contact with the lower part of the inner wall of the outer tube.

[0009] By adopting the above technical solution, the set ball bearings achieve rotational installation.

[0010] Preferably, the second composite filler has a pressure cap on one side that is in contact with the pressure cap, and the pressure cap also has a connection hole on the top for easy installation of the connecting bolt assembly.

[0011] By adopting the above technical solution, the connecting bolt group can achieve through-installation connection.

[0012] Preferably, there are four limiting boxes, and the limiting boxes are arranged in a ring array about the connecting ring.

[0013] By adopting the above technical solution, the installation and fixation are achieved through the setting of the limiting box.

[0014] Preferably, the matching groove and the recess are arranged in concentric circles.

[0015] By adopting the above technical solution, the matching slots are opened to achieve matching connection.

[0016] Preferably, the second composite filler has an overall shape that is arranged in an "L" shape.

[0017] By adopting the above technical solution, the second combination filler material is used to achieve the matching installation.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this rotary compensator is suitable for high-pressure working environments.

[0019] (1) In this case, the outer pipe structure and the inner pipe structure are equipped with an outer pipe body and a second combination of filler material. This solves the problem that the unavoidable assembly gap of the pipe compensator and the low strength of traditional sealing filler material, coupled with the effect of high temperature and high pressure medium, cause the sealing filler material to be greatly damaged during the deflection and displacement of the compensator, which makes the rotary compensator unable to adapt to the high pressure working environment. The second combination of filler material is matched and limited by the lower part of the inner pipe body. This not only has the installation limit effect on the matched second combination of filler material, but also uses the protruding part of the lower part of the inner pipe body to squeeze and limit the second combination of filler material. At the same time, the second combination of filler material is made of a mixture of non-metallic flexible filler and elastic metal filler material, thereby improving the high temperature resistance and wear resistance of the second combination of filler material.

[0020] (2) By using the following components in the outer and inner pipe structures: connecting ring, groove, ball bearing, limit box, first combined filler, rotating inner pipe, matching groove, first combined filler, and second combined filler, the existing rotary compensator is solved. This addresses the issues of large clearances between rotating components, poor stability of relative rotation between inner and outer pipes under pipeline thrust, and susceptibility to misalignment and eccentricity, increasing rotational resistance. In high-pressure pipelines, these components are prone to wear or damage, and after a period of use, they affect the sealing performance of the sealing packing, leading to seal failure and leakage. If not detected and maintained promptly, this can even cause safety accidents. The solution utilizes the following components: the first... The first and second combination fillers reduce the gap between the rotating inner tube and the outer tube. When the rotating inner tube is pushed by force, it slides into the outer tube to compress the first combination filler. When the rotating inner tube slides into the outer tube, the second combination filler is simultaneously compressed to form an automatic sealing effect. When the internal pressure of the rotating inner tube is low, the first and second combination fillers elastically recover, and the matching groove contacts the ball bearing. At this time, the rotation resistance of the rotating inner tube is reduced, so that the rotating inner tube can rotate flexibly and freely, reducing the damage to the entire piping system caused by excessive torque.

[0028] 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.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a rotary compensator suitable for high-voltage working environments, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes an outer tube structure 1, which includes an outer tube body 101 with a connecting hole. A connecting ring 102 with a groove 103 is fixedly installed inside the outer tube body 101. The groove 103 is provided with a rotating ball bearing 104. A limit box 105 is fixedly installed on the surface of the connecting ring 102. A first combined filler 106 is placed inside the limit box 105. There are four limit boxes 105, which are arranged in a circular array about the connecting ring 102. By setting four of the above components, not only is the equidistant installation of the components reflected, but also the equidistant aesthetics and practicality of the installation of the components. Furthermore, by setting four of the above components, the axial and longitudinal symmetry of the components is reflected. At the same time, the multiple limit boxes 105 on the surface of the connecting ring 102 provide limited installation of the first combined filler 106.

[0030] like Figure 5 and Figure 6As shown, the outer tube structure 1 has an inner tube structure 2 inside. The inner tube structure 2 includes a rotating inner tube 201 with a matching groove 202 at one end. The matching groove 202 and the groove 103 are arranged concentrically. When the two are arranged concentrically, it not only reflects the concentricity and coaxiality of the two, but also reflects the practicality of the contact installation. Furthermore, when the two are arranged concentrically, it reflects the fixed installation of the ball 104 and the relative rotation adjustment of the contact between the two. The rotating inner tube 201 connects with the ball 104 through the matching groove 202. The bead 104 is in contact with the inner tube 201, and a second combined filler 203 is provided above the inner tube 201 and is in contact with the lower inner wall of the outer tube 101. The overall shape of the second combined filler 203 is "placed in an L" structure. This not only reflects the matching installation of the above components with the outer tube 101, but also reflects the matching installation limit of the above components with the lower inner part of the outer tube 101. Furthermore, when the overall shape of the above components is "placed in an L" structure, the force compression and elastic recovery adjustment of the above components installation are reflected.

[0031] Furthermore, the second composite filler 203 has a pressure cap 204 on one side for extrusion contact, and the pressure cap 204 also has a connection hole on the top for easy installation of the connecting bolt group 205.

[0032] In the above scheme, when the internal pressure of the rotating inner tube 201 is high, the rotating inner tube 201 slides into the outer tube 101 and is squeezed by the first combined filler 106. At this time, the matching groove 202 and the ball 104 are in contact with the force, and the pressure cap 204 is simultaneously squeezed by the second combined filler 203. When the internal pressure of the rotating inner tube 201 is low, the first combined filler 106 and the second combined filler 203 elastically recover, and the rotating inner tube 201 can rotate inside the outer tube 101.
