Description

Technical Field

[0001] This invention relates to the field of non-metallic compensator technology, specifically a non-metallic compensator that is easy to disassemble and maintain. Background Technology

[0002] In industrial pipeline systems, compensators are usually installed between pipelines to compensate for displacement caused by factors such as temperature changes, vibration, or installation errors. Non-metallic compensators are widely used in chemical, power, and metallurgical fields due to their excellent corrosion resistance, high temperature resistance, and good flexibility.

[0003] However, traditional non-metallic compensators are mostly fastened to pipelines using flange bolts. This connection structure has obvious drawbacks in the disassembly and maintenance process: on the one hand, it requires the removal of a large number of bolts, which is cumbersome and time-consuming, especially in confined working environments, resulting in extremely low maintenance efficiency; on the other hand, frequent bolt removal can easily lead to wear of connecting parts, and over time, the sealing device loses its elasticity, affecting the sealing performance between the compensator and the pipeline, and thus causing problems such as media leakage. This not only increases the risk of equipment operation, but may also cause energy waste or environmental pollution.

[0004] In addition, the lack of filter components at both ends of the compensator means that impurities or particulate matter are often mixed in with the medium during the pipeline system's transport of the medium. The long-term accumulation of these impurities will cause erosion and wear on the flexible parts of the compensator, shortening its service life. If filter components are installed directly inside, the transport must be stopped and the compensator must be disassembled before cleaning and replacement, which is cumbersome and reduces maintenance efficiency.

[0005] Therefore, in view of the problems of inconvenient disassembly and assembly, low maintenance efficiency, easily affected sealing performance, and lack of impurity filtration protection of existing non-metallic compensators, there is an urgent need to develop a non-metallic compensator that can achieve quick disassembly and assembly, reliable sealing, and has filtration function, so as to meet the needs of efficient, safe and stable operation of industrial pipeline systems. Summary of the Invention

[0006] To address the problems in the prior art, this invention provides a non-metallic compensator that is easy to disassemble and maintain.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a non-metallic compensator that is easy to disassemble and maintain, including a pipe, and a compensator is detachably connected between two pipes through an installation mechanism. The installation mechanism is equipped with a sealing mechanism and a filtering mechanism.

[0008] Specifically, the installation mechanism includes a fixing frame, with symmetrical fixing frames welded to the opposite ends of the two pipes. A slot is provided on one side of the fixing frame, with the top of the slot extending to the outside of the fixing frame.

One end of the filter screen is engaged with the first connecting plate through a protruding locking block and a recessed locking groove, and the other end of the filter screen is engaged with the sliding second connecting plate through a protruding locking block and a recessed locking groove.

[0015] Specifically, a locking mechanism is installed at both ends of the compensator. The locking mechanism includes a slot. The inner sides of the top ends of the two fixing brackets are respectively provided with slots. One end of the slot is connected to the inner side of the slot. Symmetrical locking pins are installed on the inner sides of the top of both ends of the compensator. The locking pins are slidably connected to the inside of the compensator through a return spring. One end of the locking pin extends to the outside of the compensator and engages with the inside of the slot. Top blocks are installed at both ends of the handle and at the opposite ends of the two locking pins. The top blocks have a spiral structure. The top block at the end of the handle abuts against the top block at the end of the locking pin.

[0016] Specifically, each of the two airbags has a pressure plate installed on one side. The pressure plate is slidably connected to the inside of the fixing frame through the airbag. A pressure block is installed at the center of the opposite side of the two pressure plates, and one end of the pressure block extends into the slot.

[0017] Specifically, a limiting mechanism is installed inside both ends of the compensator. The limiting mechanism includes a rubber plug. A rubber plug is installed at the center of the inner side of the top of the two fixing frames. The rubber plug is longitudinally slidably connected to the fixing frame through a compression spring. The bottom of the rubber plug extends to the outside of the fixing frame. A limiting rod is fixedly connected at the center of the top of the rubber plug. A limiting hole is provided at the center of one side of the rotating shaft. The top of the limiting rod engages with the inside of the limiting hole.

[0018] Specifically, a cleaning mechanism is installed on the fixed frame. The cleaning mechanism includes a movable groove. Each of the two fixed frames has a movable groove on one side. The movable groove is connected to the connecting groove. The first connecting plate and the two second connecting plates are slidably connected to the inside of the connecting groove. The first connecting plate and the second connecting plates are both made of rubber. A control plate is installed at the center of one side of the first connecting plate. One end of the control plate extends to the outside of the fixed frame. The control plate is slidably connected to the inside of the fixed frame. The filter screen has a foldable wavy structure.

[0019] Specifically, each of the two fixed frames has a cover plate installed on one side. The cover plate is detachably connected to the outside of the fixed frame by bolts. The cover plate is located outside the movable groove and abuts against the outside of the second connecting plate. One end of the control plate is slidably connected to the outside of the bottom of the cover plate, and one end of the control plate is provided with a pull groove.

[0020] Specifically, each of the two fixing frames has a protrusion installed inside one side. The protrusion is a semi-cylindrical structure. The two second connecting plates and the first connecting plate are provided with multiple positioning grooves on one side. The second connecting plate and the first connecting plate are slidably connected to the protrusion through the positioning grooves. The positioning grooves on the second connecting plate and the first connecting plate located on the outside of the fixing frame are only through at one end.

Detailed Implementation

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] like Figure 1 , Figure 7 and Figure 8 As shown, a non-metallic compensator of the present invention that is easy to disassemble and maintain includes a pipe 1, and a compensator 3 is connected between two pipes 1. The two ends of the compensator 3 are detachably connected to the two pipes 1 through an installation mechanism 2. A sealing mechanism 6 and a filtering mechanism 7 are installed inside the installation mechanism 2.

[0042] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the installation mechanism 2 includes a fixing frame 201. Symmetrical fixing frames 201 are welded to the opposite ends of the two pipes 1. A U-shaped groove 203 is provided on one side of the fixing frame 201. The top of the groove 203 extends to the outside of the fixing frame 201. The two ends of the compensator 3 are longitudinally slidably connected to one side of the two fixing frames 201 through the groove 203. Through the welding of the two fixing frames 201, the two ends of the compensator 3 can be detachably engaged with the two pipes 1 with the cooperation of the groove 203, which is convenient for installation. At the same time, the compensator 3 can be disassembled by pulling it upwards. No large number of bolts are required for fastening. The operation is convenient and the maintenance efficiency is high.

[0043] Specifically, such as Figure 3 and Figure 5 As shown, the fixing frame 201 has a frame structure, and the two ends of the compensator 3 have a "convex" shaped structure. The top sides of the two ends of the compensator 3 are flush with the top of the fixing frame 201, which facilitates the flow of liquid inside the pipe 1, and at the same time makes the edge of the end of the compensator 3 firmly locked with the inside of the slot 203 and prevents it from loosening.

[0044] Specifically, such as Figure 4 , Figure 6 and Figure 8 As shown, handles 202 are installed on the top of both ends of the compensator 3. The handles 202 have a U-shaped structure. The handles 202 are rotatably connected to the top of the compensator 3 through a pivot 204. The maximum rotation angle between the handles 202 and the compensator 3 is 90 degrees. The installation of the handles 202 facilitates the holding and lifting of the compensator 3, thereby enabling the assembly and disassembly of the compensator 3. With the cooperation of the pivot 204, the handles 202 can rotate with the top of the compensator 3, making it easy to rotate and fold for storage when not in use.

[0045] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, the sealing mechanism 6 includes a mounting groove 601. The inner edges of the two fixing brackets 201 are provided with mounting grooves 601. A sealing ring 602 is engaged inside the mounting groove 601. The edges of both ends of the compensator 3 abut against one side of the sealing ring 602. The mounting groove 601 facilitates the installation of the sealing ring 602. After the compensator 3 is engaged with the fixing bracket 201, the sealing ring 602 seals the space between the compensator 3 and the fixing bracket 201, ensuring that liquid cannot overflow.

[0046] Specifically, such as Figure 4 and Figure 7 As shown, two airbags 603 are respectively installed on the inner top of the two fixing frames 201. One end of each airbag 603 is connected to the sealing ring 602 through a connecting pipe 606. With the installation of the airbags 603 and the cooperation of the connecting pipe 606, the gas inside the sealing ring 602 can enter the airbag 603 for storage, which plays a buffering role and prevents the sealing ring 602 from losing its elasticity due to long-term compression, thus reducing its service life.

[0047] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, the filter mechanism 7 includes a connecting groove 701. The inner sidewalls of the two fixed brackets 201 are provided with connecting grooves 701. Filter screens 702 are installed inside the two fixed brackets 201 through the connecting grooves 701. The opening of the connecting grooves 701 facilitates the installation of the filter screens 702, making the filter screens 702 installed stably and preventing them from sliding. The installation of the filter screens 702 facilitates the filtration of the inside of the pipe 1, preventing impurities from entering and affecting subsequent production.

[0048] Specifically, such as Figure 4 , Figure 10 , Figure 11 and Figure 12As shown, a first connecting plate 703 is installed on the inner side of one end of each of the two fixing brackets 201, and two second connecting plates 704 are installed on the other end of each of the two fixing brackets 201. Multiple buffer springs 705 are connected between the two second connecting plates 704. One of the second connecting plates 704 is slidably connected to the inside of the fixing bracket 201 through the buffer spring 705. One end of the filter screen 702 is engaged with the first connecting plate 703 through a protruding locking block and a recessed locking groove, and the other end of the filter screen 702 is engaged with the sliding second connecting plate 704 through a protruding locking block and a recessed locking groove. Through the cooperation of the first connecting plate 703 and the two second connecting plates 704, the two ends of the filter screen 702 can be detachably connected. Through the cooperation of the buffer springs 705, one of the second connecting plates 704 can slide elastically, so that the filter screen 702 has a certain buffering effect and prevents the filter screen 702 from being squeezed and pulled by liquid after being blocked.

[0049] Specifically, such as Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, locking mechanisms 4 are installed at both ends of the compensator 3. Each locking mechanism 4 includes a slot 401. Slots 401 are provided on the inner sides of the top ends of the two fixing brackets 201. One end of each slot 401 communicates with the inner side of a slot 203. Symmetrical locking pins 402 are installed on the inner sides of the top ends of both ends of the compensator 3. The locking pins 402 are slidably connected to the inside of the compensator 3 via a return spring 404. One end of each locking pin 402 extends to the outside of the compensator 3 and engages with the inside of the slot 401. Top blocks 403 are installed at both ends of the handle 202 and at the opposite ends of the two locking pins 402. The top blocks 403 have a spiral structure, and the top blocks 403 at the end of the handle 202 abut against the top blocks 403 at the end of the locking pins 402. With the slot 401 opened, after the compensator 3 and the fixing frame 201 are locked and stable, the handle 202 can be rotated to fold and store it. The top blocks 403 at both ends of the handle 202 will rotate accordingly. Since the top blocks 403 are spiral structures, they will press the top blocks 403 on the locking pin 402 to slide, thereby allowing the locking pin 402 to get rid of the elastic force of the return spring 404 and slide into the slot 401, thus limiting the position between the compensator 3 and the fixing frame 201. The compensator 3 cannot slide up for disassembly. When disassembling, the handle 202 is rotated 90 degrees, and the locking pin 402 is reset without external force. After the locking pin 402 is separated from the slot 401, it is easy to pull the handle 202 to disassemble and maintain the compensator 3.

[0050] Specifically, such as Figure 7As shown, pressure plates 604 are installed on one side of each of the two airbags 603. The pressure plates 604 are slidably connected to the inner side of the fixing frame 201 through the airbags 603. Pressure blocks 605 are installed at the center of the opposite sides of the two pressure plates 604. One end of the pressure block 605 extends into the slot 203. The installation of the pressure plates 604 facilitates the contact of one side of the airbags 603. When the compensator 3 and the fixing frame 201 are locked, the locking pin 402 contacts the pressure block 605. The pressure block 605 drives the pressure plates 604 to slide, allowing the gas inside the airbags 603 to enter the sealing ring 602. The sealing ring 602 expands and seals the compensator 3 and the fixing frame 201 tightly.

[0051] Specifically, such as Figure 6 and Figure 8 As shown, limit mechanisms 5 are installed inside both ends of the compensator 3. Each limit mechanism 5 includes a rubber plug 501. A rubber plug 501 is installed at the center of the inner side of the top of each of the two fixed frames 201. The rubber plug 501 is longitudinally slidably connected to the fixed frame 201 via a compression spring 503. The bottom of the rubber plug 501 extends to the outside of the fixed frame 201. A limit rod 504 is fixedly connected to the center of the top of the rubber plug 501. A limit hole 502 is provided at the center of one side of the rotating shaft 204. The top of the limit rod 504 engages with the inside of the limit hole 502. This mechanism is used to connect the compensator 3 to the fixed frame 201. After the installation is stable and the lock is secure, during the conveying operation, the fixed frame 201 has a certain pressure inside, which pushes the piston 501 to rise out of the elastic force of the compression spring 503. The piston 501 drives the limit rod 504 to engage with the limit hole 502, thereby limiting the rotating shaft 204. The handle 202 cannot be rotated to unlock, which plays a safety protection role. When the conveying operation stops, the piston 501 is no longer under pressure and resets under the elastic force of the compression spring 503. The limit rod 504 separates from the limit hole 502, which makes it easier to rotate the handle 202 to unlock and realize the disassembly and assembly of the compensator 3.

[0052] Specifically, such as Figure 2 , Figure 3 , Figure 4 and Figure 12As shown, a cleaning mechanism 8 is installed on the fixed frame 201. The cleaning mechanism 8 includes a movable groove 805. Movable grooves 805 are respectively provided on one side of the two fixed frames 201. The movable grooves 805 communicate with the connecting grooves 701. A first connecting plate 703 and two second connecting plates 704 are slidably connected to the inside of the connecting grooves 701. The first connecting plate 703 and the second connecting plates 704 are both made of rubber. A control plate 803 is installed at the center of one side of the first connecting plate 703. One end of the control plate 803 extends to the outside of the fixed frame 201 and is slidably connected to the inside of the fixed frame 201. The filter screen 702 has a foldable wavy structure. The opening of the movable grooves 805 facilitates the extension of the second connecting plates 704 to the outside of the fixed frame 201. The second connecting plates 704 block the movable grooves 805, preventing internal liquid from overflowing. During cleaning, the second connecting plates 704 are prevented from sliding out by contacting them. By pulling the control plate 803, the control plate 803 drives the first connecting plate 702. 3. Sliding: The first connecting plate 703 pushes the end of the filter screen 702, causing the filter screen 702 to fold. When the filter screen 702 is fully folded, it drives one of the second connecting plates 704 to slide away from the elastic force of the buffer spring 705, allowing the first connecting plate 703 to block the movable groove 805. Finally, the resistance of the second connecting plate 704 is removed, allowing both second connecting plates 704 to slide out. At the same time, the folded filter screen 702 is also extended for easy cleaning or replacement. After cleaning or replacement, the filter screen 702 is opened. Pulling the control plate 803 prevents the first connecting plate 703 from separating from the movable trough 805 and leaking liquid. After connecting the new filter screen 702 to the first connecting plate 703 and the second connecting plate 704, push it into the movable trough 805. After the two second connecting plates 704 are completely slid into the movable trough 805, the second connecting plates 704 block the movable trough 805. At this time, by pushing the control plate 803, the first connecting plate 703 drives the filter screen 702 to slide into the fixed frame 201 and unfold, realizing the filtration work.

[0053] Specifically, such as Figure 1 and Figure 2 As shown, two fixed brackets 201 are respectively equipped with cover plates 801 on one side. The cover plates 801 are detachably connected to the outside of the fixed brackets 201 by bolts 802. The cover plates 801 are located outside the movable groove 805 and abut against the outside of the second connecting plate 704. One end of the control plate 803 is slidably connected to the bottom outside of the cover plate 801. One end of the control plate 803 is provided with a pull groove 804. Through the installation of the cover plate 801, the movable groove 805 is blocked with the cooperation of the bolts 802, thereby achieving anti-slip contact with the second connecting plate 704. The control plate 803 extends to the outside of the cover plate 801, which facilitates the pulling of the first connecting plate 703 to achieve the folding of the filter screen 702. Finally, the cover plate 801 is removed, so that the second connecting plate 704 drives the filter screen 702 to slide out for cleaning or replacement.

[0054] Specifically, such as Figure 3 , Figure 11 and Figure 12 As shown, protrusions 806 are respectively installed inside one side of the two fixing brackets 201. The protrusions 806 are semi-cylindrical structures. Multiple positioning grooves 807 are provided on one side of the two second connecting plates 704 and the first connecting plate 703. The second connecting plates 704 and the first connecting plate 703 are slidably connected to the protrusions 806 through the positioning grooves 807. The positioning grooves 807 on the side of the second connecting plate 704 and the first connecting plate 703 located on the outside of the fixing bracket 201 are only penetrating at one end. One of the second connecting plates 704 can slide smoothly inside the movable groove 805, serving as a guide. Meanwhile, since the other second connecting plate 704 and the positioning groove 807 on one side of the first connecting plate 703 do not penetrate each other, the protrusion 806 serves as a limit. When the first connecting plate 703 slides to one end of the movable groove 805, it is blocked by the protrusion 806 and cannot slide out. The second connecting plate 704 will not slide into the inner side of the fixing frame 201 when the filter screen 702 unfolds, thus blocking the movable groove 805.

[0055] In use, this invention firstly, through the welding of two fixing brackets 201, and with the cooperation of the slots 203, the two ends of the compensator 3 can be detachably engaged with the two pipes 1, making installation convenient. Simultaneously, disassembly is achieved by pulling the compensator 3 upwards, eliminating the need for numerous bolts, making operation convenient and maintenance efficient, facilitating the flow of liquid inside the pipes 1, and ensuring a secure engagement between the edge of the compensator 3 and the slots 203. The installation of the handle 202 facilitates the holding and extraction of the compensator 3, enabling disassembly and assembly. With the cooperation of the rotating shaft 204, the handle 202 can rotate with the top of the compensator 3, allowing for easy folding and storage when not in use. The slot 401 further facilitates the connection between the compensator 3 and the fixing brackets 201. After the fixed frame 201 is securely engaged, it can be folded and stored by rotating the handle 202. The top blocks 403 at both ends of the handle 202 will rotate accordingly. Since the top blocks 403 have a spiral structure, they will press against the top blocks 403 on the locking pin 402, causing the locking pin 402 to slide into the slot 401 without being resisted by the spring force of the return spring 404. This limits the position between the compensator 3 and the fixed frame 201, preventing the compensator 3 from sliding upwards for disassembly. During disassembly, rotating the handle 202 90 degrees will allow the locking pin 402 to return to its original position without external force. After the locking pin 402 separates from the slot 401, it is easy to pull the handle 202 to disassemble and maintain the compensator 3. Once the compensator 3 and the fixed frame 201 are securely installed and locked, the fixed frame 201 will be able to move during transport. Internal pressure pushes the piston plug 501 upwards, freeing it from the elastic force of the compression spring 503. The piston plug 501 drives the limiting rod 504 to engage with the limiting hole 502, thus limiting the rotation of the shaft 204. The handle 202 cannot be rotated to unlock, providing a safety protection function. When the conveying operation stops, the piston plug 501, without pressure resistance, resets under the elastic force of the compression spring 503. The limiting rod 504 separates from the limiting hole 502, facilitating the rotation of the handle 202 to unlock and allow for the assembly and disassembly of the compensator 3. The installation groove 601 facilitates the installation of the sealing ring 602. After the compensator 3 engages with the fixing frame 201, the sealing ring 602 seals the space between the compensator 3 and the fixing frame 201, preventing liquid leakage. The airbag 60... The installation of component 3, in conjunction with connecting pipe 606, allows gas inside sealing ring 602 to enter and be stored inside airbag 603, acting as a buffer to prevent elastic failure of sealing ring 602 due to prolonged compression, thus reducing its service life. The installation of pressure plate 604 facilitates contact with one side of airbag 603. With the installation of pressure block 605, when compensator 3 and fixing frame 201 are locked, locking pin 402 contacts pressure block 605, causing pressure block 605 to drive pressure plate 604 to slide, allowing gas inside airbag 603 to enter sealing ring 602. The expansion of sealing ring 602 creates a tight seal between compensator 3 and fixing frame 201. The opening of connecting groove 701 facilitates the installation of filter screen 702, ensuring stable installation and preventing slippage.The installation of filter screen 702 facilitates filtration of the inside of pipe 1, preventing impurities from entering and affecting subsequent production. The cooperation of the first connecting plate 703 and two second connecting plates 704 enables detachable connection at both ends of filter screen 702. With the assistance of buffer spring 705, one of the second connecting plates 704 can slide elastically, providing a buffering effect to filter screen 702 and preventing it from being damaged by liquid pressure after clogging. The opening of the movable groove 805 allows the second connecting plate 704 to extend to the outside of the fixed frame 201. When the second connecting plate 704 blocks the movable groove 805, internal liquid will not overflow. During cleaning, the second connecting plate is pushed against... 704. To prevent the second connecting plate 704 from sliding out, the control plate 803 is pulled, causing the first connecting plate 703 to slide. The first connecting plate 703 pushes the end of the filter screen 702, folding the filter screen 702. When the filter screen 702 is fully folded, it drives one of the second connecting plates 704 to slide away from the elastic force of the buffer spring 705, thus blocking the movable groove 805. Finally, the resistance of the second connecting plate 704 is removed, allowing both second connecting plates 704 to slide out. At the same time, the folded filter screen 702 is also extended for easy cleaning or replacement. After cleaning or replacement, the first connecting plate 704 is prevented from sliding out by pulling the control plate 803. After separating the leaking fluid from the movable tank 805, the new filter screen 702 is connected to the first connecting plate 703 and the second connecting plate 704 and pushed into the movable tank 805. After the two second connecting plates 704 are completely slid into the movable tank 805, the second connecting plates 704 block the movable tank 805. At this time, by pushing the control plate 803, the first connecting plate 703 drives the filter screen 702 to slide into the fixed frame 201 and unfold, realizing the filtration work. Through the installation of the cover plate 801, the movable tank 805 is blocked with the cooperation of the bolts 802, thereby achieving anti-slip of the second connecting plate 704. The control plate 803 extends to the outside of the cover plate 801, which facilitates the first connecting plate 702. Pull 03 to fold the filter screen 702, and finally remove the cover plate 801, allowing the second connecting plate 704 to slide out the filter screen 702 for cleaning or replacement. Through the installation of the protrusion 806, one of the second connecting plates 704 can slide smoothly inside the movable groove 805, acting as a guide. Simultaneously, because the other second connecting plate 704 and the positioning groove 807 on one side of the first connecting plate 703 do not penetrate, the protrusion 806 acts as a limit. When the first connecting plate 703 slides to one end of the movable groove 805, it is blocked by the protrusion 806 and cannot slide out. The second connecting plate 704 will not slide into the inner side of the fixing frame 201 when the filter screen 702 unfolds, thus blocking the movable groove 805.
