Description

Technical Field

[0001] The utility model relates to the technical field of corrugated compensators, in particular to an axial corrugated compensator. Background Art

[0002] Bellows compensator is a kind of compensating element, which utilizes the effective expansion and contraction of its working body, the bellows, to absorb the dimensional changes of pipelines, ducts, containers, etc. caused by thermal expansion and contraction, or compensate for the axial, lateral and angular displacement of pipelines, ducts, containers, etc. It can also be used to reduce noise and vibration, and is widely used in modern industry. Bellows compensator, also commonly called expansion joint, or telescopic joint, consists of the bellows constituting its working body and end pipes, brackets, flanges, ducts and other accessories.

[0003] The existing public patent number is: CN219692595U. An axial type corrugated compensator relates to the technical field of corrugated compensators, including a connecting pipe, and the outer surface of the connecting pipe is provided with compensation corrugations. In the utility model, when installing the screw rod, the screw rod is passed through one of the connecting ears and then the two first nuts are installed, and then the screw rod is passed through the other connecting ear, and then the two second nuts are installed. When the second nut is installed, the second meshing ring is driven to rotate, and the outer surface squeezes the first meshing ring, so that the damper and the spring are contracted. After the installation is completed, the damper cooperates with the spring to squeeze the first meshing ring so that it fits tightly with the second meshing ring. Since the surfaces of the first meshing ring and the second meshing ring are triangular meshing teeth, they can only rotate in one direction, thereby solving the problem that the second nut is easy to loosen or even detach from the screw rod when the connecting pipe cooperates with the compensation corrugation to expand and contract, and the firmness is greatly improved, which improves the stability of the device.

[0004] The above solution solves the problem that the second nut is easy to loosen or even detach from the screw rod when the connecting pipe cooperates with the compensation corrugation expansion and contraction. The firmness is greatly improved, and the stability of the device is improved. The device uses traditional screws for installation when installing the pipeline. The pipelines at both ends need to be installed with screws, and the installation is very troublesome. When the staff installs a large number of pipes, it will increase a lot of installation time and the efficiency is low. Utility Model Content

[0012] As a preferred embodiment, a plurality of the side blocks 1 are movably embedded with threaded rods 2, and a plurality of the threaded rods 2 are movably embedded in a plurality of circular holes.

[0013] The technical effect of adopting the above further solution is that when the second threaded rod is embedded in the circular hole, the clamping of the sliding block on the pipe is more stable.

[0014] As a preferred embodiment, a telescopic hose is fixedly connected to the outer surface of the two flanges on one side opposite to each other, and a spring is fixedly connected to the outer surface of the two flanges on one side opposite to each other.

[0015] The technical effect of adopting the above further solution is that the thermal expansion and contraction of the pipeline causes the flange to move closer to or farther away from the center under the limitation of the spring.

[0016] As a preferred implementation, the spring is located on the outer surface of the telescopic hose, and the outer surface of one of the flanges is fixedly connected to two fixing blocks.

[0017] The technical effect of adopting the above further solution is that the telescopic hose can be extended and retracted, which is convenient for the thermal expansion and contraction of the pipes at both ends and can be extended and shortened.

[0018] As a preferred embodiment, the outer surfaces of the two fixing blocks are fixedly connected with limiting rods, the outer surface of the other flange is fixedly connected with two sleeve blocks, and the two limiting rods are movably embedded inside the two sleeve blocks.

[0019] The technical effect of adopting the above further solution is that the limiting rod is movably embedded in the interior of the sleeve block to limit the two flanges when in use.

[0020] Compared with the prior art, the advantages and positive effects of the utility model are:

[0021] 1.

At this time, the L-shaped plate can be rotated in a circular and transverse semicircular manner around the bottom block. At this time, the pipeline can be pulled out and disengaged from the outer surface of the flange. When the pipeline is installed and used, the pipeline expands and contracts due to heat and cold, and the flange moves closer to and away from the middle under the limitation of the spring. The limiting rod is movably embedded in the inside of the sleeve to limit the two flanges when in use. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0030] See also Figure 1-4 The utility model provides an axial corrugated compensator, including: two flanges 101 and multiple L-shaped plates 107, multiple L-shaped plates 107 are provided with slide grooves 110 inside, multiple L-shaped plates 107 are movably embedded with threaded rods 108 inside, one end of multiple threaded rods 108 are rotatably connected with sliders 109 through bearings, multiple sliders 109 are slidably connected inside the multiple slide grooves 110, the pipeline is aligned with the two sides of the two flanges 101, and then the threaded rods 108 around are rotated to move the sliders 109 under the limit of the slide grooves 110. When the sliders 109 move, the pipeline can be clamped and fixed. Compared with the traditional screw installation, it saves time, has a short installation time and high efficiency.

[0031] like Figure 1-4 As shown, the outer surfaces of the two flanges 101 are fixedly connected with a plurality of bottom blocks 111, and the outer surfaces of the plurality of bottom blocks 111 are fixedly connected with a second side block 114. When the pipeline needs to be disassembled, the second threaded rod 113 is rotated to disengage from the inside of the circular hole 115 on the second side block 114. At this time, the L-shaped plate 107 can rotate in a circular and transverse semicircular manner around the bottom block 111, and the pipeline can be pulled out and disengaged from the outer surface of the flange 101.

[0032] like Figure 1-4As shown, the outer surfaces of the two flanges 101 are fixedly connected with a plurality of bottom blocks 111, and the outer surfaces of the plurality of bottom blocks 111 are fixedly connected with a second side block 114. When the pipeline needs to be disassembled, the second threaded rod 113 is rotated to disengage from the inside of the circular hole 115 on the second side block 114. At this time, the L-shaped plate 107 can rotate in a circular and transverse semicircular manner around the bottom block 111, and the pipeline can be pulled out and disengaged from the outer surface of the flange 101.

[0033] like Figure 1-4 As shown, multiple side blocks 112 are movably embedded with threaded rods 113, and multiple threaded rods 113 are movably embedded in multiple circular holes 115. When the threaded rods 113 are embedded in the circular holes 115, the slider 109 clamps the pipe more stably.

The thermal expansion and contraction of the pipelines are limited by the springs 103, causing the flanges 101 to move closer to and away from the middle.

[0035] like Figure 1-4 As shown, the spring 103 is located on the outer surface of the telescopic hose 102, and two fixing blocks 104 are fixedly connected to the outer surface of one flange 101.

When the slider 109 moves, the pipe can be clamped and fixed. When the pipe needs to be disassembled, rotate the threaded rod 113 to disengage from the inside of the circular hole 115 on the side block 114. At this time, the L-shaped plate 107 can rotate in a circular and semi-circular manner around the bottom block 111. At this time, the pipe can be pulled out and disengaged from the outer surface of the flange 101. Compared with the traditional screw installation, it saves time, has a shorter installation time and high efficiency. When the pipe is installed and used, the pipe expands and contracts due to heat and cold under the limit of the spring 103, so that the flange 101 moves closer to and away from the middle. The limit rod 105 is movably embedded in the inside of the sleeve block 106 to limit the two flanges 101 when in use.
