Description

Technical Field

[0001] The utility model relates to the technical field of pipeline compensators, in particular to a pipeline compensator convenient for installation. Background Technique

[0002] A pipeline compensator, also known as an expansion joint or expansion section, is mainly used to compensate for the thermal expansion and contraction of pipelines caused by temperature changes. If the pipeline cannot expand or contract freely when the temperature changes, thermal stress will be generated in the pipeline. This stress must be considered in pipeline design, otherwise it may cause the pipeline to rupture and affect normal production. As an important part of pipeline engineering, the compensator plays an important role in ensuring the long-term normal operation of pipelines.

[0003] A pipeline compensator convenient for installation disclosed in the existing patent (publication number: CN220706738U) inserts a positioning disk into the inside of a fixed disk through a connecting pipe. The positioning disk rotates 90 degrees, and the rotating rod drives the bent rod to move downward, so that the limiting block extends into the inside of the fixed disk, and the pipeline compensator main body and the connecting pipe can be quickly installed. The installation efficiency is greatly improved, and the overall structure is simple and convenient for popularization.

[0004] However, the above technical solution still has certain defects. After the above device inserts the positioning disk into the inside of the fixed disk and rotates 90 degrees, it is necessary for the staff to rotate the rotating rod in turn to extend the limiting block into the inside of the fixed disk to complete the quick installation of the pipeline compensator main body and the connecting pipe. The process of fixing and installing or removing is relatively cumbersome and inconvenient, and it is time-consuming and laborious. Therefore, a pipeline compensator convenient for installation is proposed. Content of the Utility Model

[0014] In summary, the present utility model mainly has the following beneficial effects:

[0015] 1. By pulling the annular pull rod of the present utility model, the two groups of movable insertion rods are driven to move upward, thereby driving the limiting ring fixed thereto to move upward, further squeezing the first spring. Subsequently, hold the connecting pipe by hand and adjust the position of the positioning block so that it is above the clamping groove. Then, insert the positioning disc into the fixed disc, and rotate the connecting pipe clockwise by 90 degrees so that the positioning block is above the trapezoidal block and the clamping block is directly above the clamping groove.

By using this fixing component, the disassembly and assembly efficiency of the docking of the connecting pipe and the pipeline compensator main body by the staff is greatly improved;

[0016] 2. By the staff inserting the positioning disc into the fixed disc of the present utility model, the sealing gasket is driven to insert into the sealing groove. The sealing gasket can increase the sealing performance between the pipeline compensator main body and the connecting pipe, and is relatively convenient to use. When the positioning block squeezes the trapezoidal block to move downward to the lower part of the sealing chamber, the connecting block and the piston are driven to move downward synchronously, squeezing the nitrogen gas below the sealing chamber and transporting it through the gas transmission pipe to the airbag gasket. The airbag gasket expands and further squeezes and fits the sealing gasket, making the sealing effect further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0027] The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0028] A pipe compensator convenient for installation, as Figures 1 - 5 shown, includes a pipe compensator main body 100. Fixed disks 110 are fixedly installed at both the upper and lower ends of the pipe compensator main body 100. A positioning disk 130 is installed inside the fixed disk 110. A connecting pipe 120 is provided at the top of the positioning disk 130. The fixed disk 110 and the connecting pipe 120 are docked through a fixing component 200. A sealing component 300 is provided at the docking portion of the fixed disk 110 and the connecting pipe 120;

[0029] The fixing component 200 includes two groups of symmetrically arranged fixed sleeves 240 fixedly installed on the outer wall of the connecting pipe 120. A moving insertion rod 250 is longitudinally arranged inside the fixed sleeve 240. A limiting ring 260 is fixedly sleeved on the outer wall of the moving insertion rod 250 inside the fixed sleeve 240. A first spring 270 is fixedly installed between the upper surface of the limiting ring 260 and the top of the inner cavity of the fixed sleeve 240. The first spring 270 is sleeved on the outer wall of the moving insertion rod 250. The bottom of the moving insertion rod 250 penetrates through the bottom of the fixed sleeve 240 and is fixedly connected with a clamping block 280. An annular groove 210 is opened on the inner side wall of the fixed disk 110. Card slots 220 communicating with the annular groove 210 are opened on both sides of the top of the inner side wall of the fixed disk 110. A positioning block 230 matching the card slot 220 is fixedly connected to the outer wall of the positioning disk 130, and the positioning block 230 is movably connected inside the annular groove 210. The tops of the two groups of moving insertion rods 250 both penetrate through the top of the fixed sleeve 240 and are fixedly connected with the same annular pull rod 290. The number of the positioning blocks 230 is two, and the two positioning blocks 230 are symmetrically arranged with the vertical center line of the positioning disk 130 as the axis of symmetry.

[0030] First, the staff member pulls the annular pull rod 290, driving the two groups of movable insertion rods 250 to move upward, thereby driving the fixed limit ring 260 to move upward, further compressing the first spring 270. It should be noted that the first spring 270 is in a compressed state initially. Subsequently, the staff member holds the connecting pipe 120 and adjusts the position of the positioning block 230 so that it is above the card slot 220. Then, the positioning disk 130 is inserted into the interior of the fixed disk 110, and the connecting pipe 120 is rotated clockwise by 90 degrees, causing the positioning block 230 to be above the trapezoidal block 340, and the clamping block 280 to be directly above the card slot 220. Release the annular pull rod 290, and use the elastic force of the first spring 270 to drive the limit ring 260, the movable insertion rod 250, and the clamping block 280 to move downward into the interior of the card slot 220, thus completing the installation of the connecting pipe 120 to the pipeline compensator main body 100. Using this fixing component 200 greatly improves the disassembly and assembly efficiency of the staff for the docking of the connecting pipe 120 and the pipeline compensator main body 100.

[0031] Please refer particularly to Figure 1 , Figure 3 and Figure 4 As shown, the sealing component 300 includes two sealing chambers 310 opened on the inner side wall of the fixed disk 110 and communicating with the bottom of the annular groove 210. A piston 320 that matches it is movably connected inside the sealing chamber 310. A connecting block 330 is fixedly connected to the top of the piston 320. A trapezoidal block 340 is fixedly installed on the top of the connecting block 330. Second springs 350 are fixedly installed between the top of the piston 320 on both sides of the connecting block 330 and the bottom of the trapezoidal block 340.

[0032] The staff member inserts the positioning disk 130 into the interior of the fixed disk 110 and rotates the connecting pipe 120 clockwise by 90 degrees, causing the positioning block 230 to squeeze the trapezoidal block 340 and move downward to the lower part of the sealing chamber 310. At this time, the second spring 350 is compressed. The acting force of the second spring 350 can be used to tightly press the positioning block 230, further improving the firmness of the installation and reducing the problem of rotation during installation.

[0033] Please refer particularly to Figure 3 and Figure 4 As shown, an annular fixing plate 360 is fixedly connected to the inner side wall of the fixed disk 110 below the annular groove 210. A sealing groove 370 is opened on the annular fixing plate 360. A sealing pad 380 is fixedly connected to the bottom of the positioning disk 130. An airbag pad 3910 is arranged on the inner side wall of the sealing groove 370. Both ends of the airbag pad 3910 are fixedly connected to an air delivery pipe 390. The other end of each group of air delivery pipes 390 is connected to the bottom of the corresponding sealing chamber 310.

[0034] The staff inserts the positioning disk 130 into the interior of the fixed disk 110, driving the gasket 380 to insert into the sealing groove 370. The gasket 380 can enhance the sealing performance between the pipeline compensator body 100 and the connecting pipe 120, making it more convenient to use. When the positioning block 230 presses the trapezoidal block 340 to move downward to the lower part of the sealing chamber 310, it drives the connecting block 330 and the piston 320 to move downward synchronously, squeezing the nitrogen gas in the lower part of the sealing chamber 310 to be transported through the gas transmission pipe 390 into the airbag pad 3910. The airbag pad 3910 expands and further presses against the gasket 380, making the sealing effect further improved.

[0035] During use, the staff pulls the annular pull rod 290, driving the two groups of movable insertion rods 250 to move upward, thereby driving the fixed limiting ring 260 to move upward, further squeezing the first spring 270. It should be noted that the first spring 270 is in a squeezed state in its initial state. Subsequently, the staff holds the connecting pipe 120 and adjusts the position of the positioning block 230 so that it is above the clamping groove 220. Then the positioning disk 130 is inserted into the interior of the fixed disk 110, and the connecting pipe 120 is rotated clockwise by 90 degrees, making the positioning block 230 above the trapezoidal block 340 and the clamping block 280 directly above the clamping groove 220. The annular pull rod 290 is released, and the first spring 270's own elastic force drives the limiting ring 260, the movable insertion rods 250, and the clamping block 280 to move downward into the interior of the clamping groove 220, thus completing the installation of the connecting pipe 120 to the pipeline compensator body 100. Using this fixing component 200 greatly improves the disassembly and assembly efficiency of the staff for the docking of the connecting pipe 120 and the pipeline compensator body 100. The parts not involved in this device are the same as or can be implemented using the prior art.

The described specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not contribute creatively to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
