Description

An easy-to-install bidirectional sleeve compensator Technical Field

[0001] This utility model relates to the technical field of bidirectional sleeve compensators, specifically a bidirectional sleeve compensator that is easy to install. Background Technology

[0002] A bidirectional sleeve compensator is a pipeline compensation device primarily used to absorb and compensate for the deformation energy of pipelines under the influence of thermal expansion and contraction, displacement, and vibration, thereby maintaining the stability of the pipeline system. Its working principle is based on the elastic and plastic deformation of materials, absorbing the deformation energy of the pipeline through the displacement of the sleeve.

[0003] A search revealed that existing technologies, such as the maintenance-free sleeve compensator (publication number CN213393969U), include an outer cylinder (9), an inner cylinder (1) inserted inside the outer cylinder, and sealing filler between the inner and outer cylinders. The left end of the sealing filler is in contact with the sleeve of the gland (2). The inner wall of the outer cylinder is tapered, with the diameter of the left end of the inner wall being larger than the diameter of the right end. The right end of the sealing filler is in contact with the side wall (10) of the outer cylinder. The gland flange (4) of the gland is connected to the outer cylinder flange (5) of the outer cylinder by bolts (7). There is a gap between the gland flange (4) and the outer cylinder flange. A spring (6) is fitted on the bolt, located on the left side of the outer cylinder flange, and the spring is held in place by a nut (3). Its characteristic is that the inner wall of the outer cylinder is tapered, which exerts radial pressure on the sealing filler, ensuring effective sealing. After the sealing filler wears down, the radial pressure can be continuously compensated under the action of the spring. This compensates for the wear of the sealing filler, reduces maintenance workload, and maintains the sealing performance of the sleeve compensator.

[0004] In summary, existing sleeve compensators reduce maintenance workload and maintain the sealing performance of the sleeve compensator. However, the existing sleeve compensators use several sets of bolts to limit the installation of the gland, which is a relatively cumbersome installation process and requires the use of tools. Therefore, a bidirectional sleeve compensator that is easy to install is proposed. Summary of the Invention

[0005] The purpose of this utility model is to provide a bidirectional sleeve compensator that is easy to install, so as to solve the problem mentioned in the background art that the existing sleeve compensator uses several sets of bolts to limit the installation of the gland, and the installation process is relatively cumbersome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional sleeve compensator that is easy to install, comprising an inner cylinder, one end of which is inserted into the outer cylinder, and the space between the inner and outer cylinders is filled with sealing filler. The left end of the sealing filler is in contact with the pressure cap, and several sets of limiting plate mechanisms that cooperate with the pressure cap are symmetrically arranged on the outer side of the outer cylinder. The limiting plate mechanism includes a limiting plate, a limiting block is fixedly installed on one side of the limiting plate, and a limiting block groove that cooperates with the limiting block is opened on the pressure cap. The other side of the limiting plate is connected to a positioning plate through several sets of first springs, and the top of the positioning plate is located inside the opening slot. One side of the opening slot is connected to a mounting plate through a connecting post, and the mounting plate is connected to a movable plate inside the mounting box through symmetrically arranged connecting arms. The movable plate is connected to a screw mechanism that is rotatably arranged inside the mounting box, and one end of the screw mechanism is connected to a throttle handle arranged on the outside of the mounting box.

[0007] Preferably, a connecting pipe is welded to one end of the outer cylinder.

[0008] The above technical solution facilitates connection.

[0009] Preferably, a limiting rod that cooperates with the positioning plate is installed on the outside of the opening slot.

[0010] The above technical solution facilitates the disassembly and installation of the positioning plate.

[0011] Preferably, the limiting rod includes a rod, and the positioning plate has a rod groove for cooperating with the rod. One end of the rod is connected to a sliding plate that is slidably disposed inside the mounting cylinder, and the sliding plate is connected to a handle disposed on the outside of the mounting cylinder via a pull rod. The sliding plate is connected to the inner wall of the mounting cylinder via symmetrically disposed second springs.

[0012] The above technical solution facilitates the disassembly and installation of the positioning plate.

[0013] Preferably, the mounting box has a movable through slot for use with the connecting arm.

[0014] The above technical solution facilitates the movement of the connecting arm.

[0015] Preferably, the movable plate is slidably connected to the inside of the mounting box.

[0016] The above technical solution facilitates the movement of the mobile board.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-install bidirectional sleeve compensator solves the problem that the existing sleeve compensators use several sets of bolts to limit the installation of the pressure cap, which is a relatively cumbersome installation process. Instead, one end of the inner cylinder is inserted into the outer cylinder, and the space between the inner and outer cylinders is filled with sealing filler. The left end of the sealing filler is in contact with the pressure cap, and several sets of limiting plate mechanisms that cooperate with the pressure cap are symmetrically arranged on the outer side of the outer cylinder. Each limiting plate mechanism includes a limiting plate, a limiting block fixedly installed on one side of the limiting plate, and a limiting block groove that cooperates with the limiting block on the pressure cap. The other side of the limiting plate is connected to the pressure cap by several sets of first springs. The positioning plate is connected, and the top of the positioning plate is located inside the opening slot. One side of the opening slot is connected to the mounting plate through a connecting post. The mounting plate is connected to the movable plate inside the mounting box through symmetrically arranged connecting arms. The movable plate is connected to the screw mechanism inside the mounting box, and one end of the screw mechanism is connected to the handle on the outside of the mounting box. When it is necessary to limit the pressure cover, the limiting block is located on one side of the limiting block slot opened on the pressure cover. The handle is rotated, and the limiting block moves under the action of the handle. When the limiting plate and the pressure cover are pressed together, the limiting block is located inside the limiting block slot. The limiting plate and the limiting block can limit the position of the pressure cover. Attached Figure Description

[0023] 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.

[0024] Please refer to Figures 1-4. This utility model provides a technical solution: a bidirectional sleeve compensator that is easy to install. One end of the inner cylinder 1 is inserted into the outer cylinder 2. One end of the outer cylinder 2 is welded with a connecting pipe 6. The space between the inner cylinder 1 and the outer cylinder 2 is filled with sealing filler 3. The left end of the sealing filler 3 is in contact with the pressure cap 4. Several sets of limiting plate mechanisms 5 that cooperate with the pressure cap 4 are symmetrically arranged on the outer side of the outer cylinder 2.

[0025] To further clarify, the sealing filler 3 is flexible graphite.

[0026] Specifically, the limiting plate mechanism 5 includes a limiting plate 501. A limiting block 502 is fixedly installed on one side of the limiting plate 501, and a limiting block groove that cooperates with the limiting block 502 is opened on the pressure cover 4. The other side of the limiting plate 501 is connected to the positioning plate 504 through several sets of first springs 503. When the sealing packing 3 is worn, the radial pressure of the sealing packing 3 can be continuously compensated under the action of the first springs 503. The top of the positioning plate 504 is located inside the opening slot 505. One side of the opening slot 505 is connected to the mounting plate 507 through the connecting post 506. The mounting plate 507 is connected to the moving plate 5091 inside the mounting box 509 through the symmetrically arranged connecting arms 508. The moving plate 5091 is connected to the screw mechanism 5092 that is rotatably arranged inside the mounting box 509. One end of the screw mechanism 5092 is connected to the handle 5093 on the outside of the mounting box 509. The mounting box 509 is fixedly connected to the outside of the outer cylinder 2 through the connecting fixing ring.

[0027] To further explain, the mounting box 509 is provided with a movable through slot that works in conjunction with the connecting arm 508.

[0028] To elaborate further, the movable plate 5091 is slidably connected to the mounting box 509.

[0029] When it is necessary to limit the pressure cap 4, the limiting block 502 is positioned on one side of the limiting block groove opened in the pressure cap 4. At this time, the handle 5093 is rotated, and the screw mechanism 5092 rotates under the action of the handle 5093, thereby driving the moving plate 5091 and the connecting arm 508 to move. The connecting arm 508 can drive the mounting plate 507 and the connecting column 506 to move synchronously, thereby ultimately driving the limiting plate 501 and the limiting block 502 to move. When the limiting plate 501 is pressed against the pressure cap 4, the limiting block 502 is located inside the limiting block groove. The limiting plate 501 and the limiting block 502 can limit the position of the pressure cap 4.

[0030] Specifically, a limiting rod 7 is installed on the outside of the opening slot 505 to cooperate with the positioning plate 504. The limiting rod 7 includes a rod 701, and the positioning plate 504 has a rod groove to cooperate with the rod 701. One end of the rod 701 is connected to a sliding plate 703 that is slidably disposed inside the mounting cylinder 702. The sliding plate 703 is connected to a handle 705 disposed on the outside of the mounting cylinder 702 through a pull rod 704. The sliding plate 703 is connected to the inner wall of the mounting cylinder 702 through symmetrically disposed second springs 706.

[0031] When it is necessary to disassemble the positioning plate 504 to avoid affecting the installation and disassembly of the pressure cover 4, pull the handle 705. The handle 705 drives the sliding plate 703 and the insertion rod 701 to move through the pull rod 704. At this time, the second spring 706 is in a gradually compressed state. When the insertion rod 701 is completely disengaged from the insertion rod groove opened in the positioning plate 504, the positioning plate 504 can be separated from the opening slot 505.
