[0044] The water outlet pipe 3 is provided with the second mounting seat 8 on the left and right sides of the front part, and the second connecting rod 9 is movably inserted into the front end of the second mounting seat 8.

[0045] In the embodiment, the water inlet flange 11 is welded to the front part of the water inlet pipe 1, the corrugated compensation pipe 2 is fixed to the outer side of the rear end of the water inlet pipe 1, the front end of the corrugated compensation pipe 2 is welded to the outer side of the front end of the lining pipe 21, the front end of the lining pipe 21 extends to the rear side of the water outlet of the water inlet pipe 1, and the rear end of the lining pipe 21 is movably sleeved with the middle part of the water outlet pipe 3.

[0046] The lining pipe 21 is arranged in the corrugated compensation pipe 2, the lining pipe 21, the water inlet pipe 1 and the water outlet pipe 3 cooperate to provide a smooth conveying channel for the medium conveyed in the pipeline, so as to avoid the fluctuation of the medium entering the corrugated compensation pipe 2.

[0047] In this embodiment, the rear end of the water outlet pipe 3 is provided with a water outlet flange 31, and the top and bottom of the water outlet pipe 3 are inserted with a pair of limiting screws 4, the front ends of the two groups of limiting screws 4 are inserted with the top and bottom of the water inlet pipe 1, and the outer side of the limiting screw 4 is connected with a limiting nut 41.

[0048] When the device is installed in the pipeline conveying system, the limiting nut 41 needs to be loosened to facilitate the variable setting of the working distance between the water inlet pipe 1 and the water outlet pipe 3, and facilitate the deformation absorption of the corrugated compensation pipe 2 to the deformation of the pipeline conveying system.

[0049] In this embodiment, the front end of the first connecting rod 51 is divided into a first movable area 52, and the first movable area 52 is matched with the first mounting seat 5.

[0050] The first movable area 52 of the first connecting rod 51 is matched with the first mounting seat 5, which facilitates the front and rear sliding of the first connecting rod 51 under the first mounting seat 5.

[0051] In this embodiment, the front end of the second connecting rod 9 is divided into a second movable area 92, and the second movable area 92 is matched with the second mounting seat 8.

[0052] The second movable area 92 of the second connecting rod 9 is matched with the second mounting seat 8, which facilitates the front and rear sliding of the second connecting rod 9 under the second mounting seat 8.

[0053] In this embodiment, the hook claw 6 is arranged up and down about the rear end of the first connecting rod 51, the top of the hook claw 6 is fixedly provided with a reinforcing area 61, the bottom of the hook claw 6 is fixedly provided with a hook groove 62, the rear end of the hook claw 6 is movably connected with a connecting seat 7, the rear end of the connecting seat 7 is movably connected with a connecting sleeve 71, the middle parts of the two connecting sleeves 71 are respectively connected with the top and bottom of a threaded rod connecting piece 72, and the top of the threaded rod connecting piece 72 is fixedly provided with a hexagonal head.

[0054] When the product is used in the pipeline conveying system for a long time, it is necessary to replace the compensator assembly due to the influence of pipeline deformation and the increase of use time.

[0055] During the replacement operation, the hook grooves 62 of the two hook claws 6 need to be placed on the outside of the limiting rod 91. If the worker lacks electric tools, a hammer or other striking tools can be used to strike the reinforcing area 61 of the hook claw 6 to narrow the working distance between the first connecting rod 51 and the second connecting rod 9, and adjust the limiting nut 41 outside the limiting screw 4 to narrow the working distance between the water inlet pipe 1 and the water outlet pipe 3, which facilitates the worker to disassemble the compensator assembly from the pipeline conveying system.

[0056] If the worker is equipped with an electric tool, the threaded rod connecting piece 72 can be matched with the two connecting sleeves 71, the working distance between the two connecting sleeves 71 is narrowed by rotating the hexagonal head of the threaded rod connecting piece 72 by using the electric tool, the working position of the first connecting rod 51 and the second connecting rod 9 is narrowed by matching the hook claw 6 with the limiting rod 91.

[0057] The electric tool in the device is an electric wrench, which can be used to tighten the fasteners such as bolts.
