Description

Technical Field

[0001] The utility model relates to the technical field of non-metallic expansion joint compensators, and specifically relates to a flexible and telescopic non-metallic compensator. Background Technique

[0002] The elastic element that constitutes its working main body is made of non-metallic material, usually fiber fabric, so it is also called a fabric compensator (expansion joint, expansion joint), and there is also a rubber material. This material can replace fiber fabric under various working conditions except when it cannot meet the use conditions at ultra-high temperatures (above 400°C). It is widely used at the inlets and outlets of smoke desulfurization, dust removal equipment, air heating, and air-assisted blowing equipment in steel plants, smelters, petrochemical plants, thermal power plants, cement plants, and atomic power plants. It is much better than metal expansion joints and non-metallic compensators (fabric compensators, fiber fabric compensators). It can compensate axially and angularly, and has the characteristics of no thrust, simplified support design, corrosion resistance, high temperature resistance, noise reduction and shock absorption. It is especially suitable for hot air pipelines and dust pipelines.

[0003] According to the publicly disclosed patent with the patent number CN217234831U: When preventing substances from flowing inside the device, the device will not sag due to gravity at the bottom, improving the stress uniformity of the overall device during operation, ensuring that substances can flow smoothly inside the device. At the same time, the elastic band can be thread-removed from the threaded head on the connecting rod through the thread on the reserved groove, and the elastic band can be disassembled conveniently through the cooperation between the docking hole and the quick-release head. However, when disassembling and replacing the skin, the main valve needs to be closed to ensure that there is no fluid passing through during the disassembly of the skin. Therefore, when replacing the skin, the fluid transportation needs to be paused, which affects the use and is not very convenient. Content of the Utility Model

[0004] The utility model provides a flexible and telescopic non-metallic compensator, which has the advantage of being able to transport fluid even when replacing the skin, so as to solve the problem that fluid transportation needs to be stopped when replacing the skin.

[0005] To achieve the purpose of not affecting the normal fluid transportation when replacing the skin, the present utility model provides the following technical solution: a flexible and telescopic non-metallic compensator, which includes two symmetrically arranged fixed sleeves, flange plates, skins, and a fixing frame connected to the outer wall of the flange plate. The flange plates are respectively installed on the outer walls of the fixed sleeves. One end of the symmetrically arranged fixed sleeves close to each other is provided with a recessed fixing groove. Fixing rings are installed on the outer walls of the upper and lower ends of the skin, and the upper and lower fixing rings are respectively detachably installed in the upper and lower fixing grooves. Openings are symmetrically arranged on the inner walls of the symmetrically arranged fixed sleeves. A diversion pipe corresponding to the opening is provided on the outer wall of the fixed sleeve, and the diversion pipe is communicated with the opening. A telescopic hose is connected between the upper and lower diversion pipes. An opening and closing assembly is arranged in the installation sleeve, and the opening and closing assembly is used to close the installation sleeve so that the fluid can flow through the telescopic hose.

[0006] Preferably, the opening and closing assembly includes a transmission shaft, a valve, and a locking assembly. A through hole is provided on the outer wall of the fixed sleeve, and a rotating hole is provided on the inner wall of the fixed sleeve. The position of the rotating hole is opposite to the position of the through hole. The transmission shaft is rotatably connected in the rotating hole and the other end passes through the through hole and extends outwards. The transmission shaft is rotatably connected with the through hole. The valve is installed on the outer wall of the transmission shaft and is arranged in the fixed sleeve. The locking assembly is movably connected to one end of the transmission shaft extending out of the through hole. A locking groove concentric with the through hole is provided on the outer wall of the fixed sleeve. A plurality of first fixing teeth are symmetrically arranged in the locking groove, and the first fixing teeth cooperate with the locking assembly to lock the transmission shaft.

[0007] Preferably, the locking assembly includes second fixing teeth and a locking sleeve. The number, size, and installation angle of the second fixing teeth are the same as those of the first fixing teeth. A clamping groove adapted to the second fixing teeth is provided on the inner wall of the locking sleeve.

[0008] Preferably, a first sealing ring is installed on the outer wall of the valve.

[0009] Preferably, a second sealing ring is provided on the bottom wall of the fixing groove.

[0026] Based on the above Embodiment 1, please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 The locking assembly 53 includes a second fixed tooth 531 and a locking sleeve 532. The number, size and installation angle of the second fixed teeth 531 are the same as those of the first fixed teeth 171. On the inner wall of the locking sleeve 532, a clamping groove 5321 that fits the second fixed tooth 531 is provided. By providing that the locking assembly 53 includes the second fixed tooth 531 and the locking sleeve 532, and a clamping groove 5321 that fits the second fixed tooth 531 is provided in the locking sleeve 532, the locking sleeve 532 can be inserted into the locking groove 17, so that the clamping groove 5321 can simultaneously clamp the first fixed tooth 171 and the second fixed tooth 531 to lock the transmission shaft 51, and the locking method is simple, only the locking sleeve 532 needs to be inserted.

[0027] The working principle and usage process of the present utility model:

[0028] When replacing the skin 3, pull out the locking sleeve 532. At this time, the locking sleeve 532 disengages from the locking groove 17 and the rotating shaft in sequence. The clamping groove 5321 disengages from the first fixed tooth 171 and the second fixed tooth 531 along with the locking sleeve 532. Then rotate the transmission shaft 51 counterclockwise by 90°, so that the transmission shaft 51 drives the valve 52 to close the fixed sleeve 1. At this time, since the fixed sleeve 1 is closed, the fluid can be transported through the opening 12, the diversion pipe 13 and the telescopic hose 14. When disassembling the skin 3, it is not necessary to close the main valve 52. After rotating 90°, insert the locking sleeve 532 again, so that the clamping groove 5321 catches the first fixed tooth 171 and the second fixed tooth 531. Then remove the bolt, so that the bolt disengages from the second threaded hole 32 and the first threaded hole 18 in sequence, and remove the skin 3 from the fixed sleeve 1, so that the fixing ring 31 disengages from the fixing groove 11. Then install the new skin 3, insert the fixing ring 31 of the new skin 3 into the fixing groove 11, align the first threaded hole 18 and the second threaded hole 32, and install the bolt, so that the thread extends into the first threaded hole 18 and the second threaded hole 32 in sequence. When the installation is completed, pull out the locking sleeve 532, rotate the transmission shaft 51 clockwise by 90°, and then snap in the locking sleeve 532, so that the transmission shaft 51 is locked. At this time, the valve 52 is in the open state, and the fluid can pass through.
