[0002] In pipeline systems, the design of pipe column connectors becomes particularly critical, especially in situations where thermal expansion and contraction, axial displacement or other forms of deformation need to be dealt with. Traditional rigid connection methods often cannot effectively adapt to these deformations, resulting in leakage, rupture and other problems in the pipeline system. Therefore, pipe column connectors with telescopic compensation components, namely sleeve compensators, came into being.

[0003] The sleeve compensator is mainly composed of an outer sleeve, a core tube and connecting accessories. The outer sleeve and the core tube can slide relative to each other to adapt to the axial deformation of the pipeline. However, how to ensure the stability, sealing and installation convenience of the outer sleeve and the core tube during the sliding process has become an important challenge in the design of sleeve compensators.

At this time, the elastic traction plate 17 pulls the retaining ring 4 to pre-limit the retaining ring 4 on one side of the flange 10. That is, when the nut 14 is not tightened at this time, the retaining ring 4 will not be pulled out from the outer sleeve 1.

[0026] The other end of the retaining ring 4 is fixed with a plug rod 19, which passes through the flange 11, and one end of the plug rod 19 is plugged with two sets of blocks 43, the screw 13 corresponds to the bolt hole 12, the screw 13 passes through the bolt hole 12, the plug rod 19 and the screw 13 correspond one to one, the plug rod 19 and the screw 13 are symmetrically distributed about the end plate of the retaining ring 4, and the plug rod 19 passes through the bolt hole 12 on the surface of the flange 11; one end of the plug rod 19 is provided with a mounting groove 20, and the mounting groove 20 is an annular groove, and the mounting groove 20 is provided. The surface of the mounting groove 20 is provided with two slots 21, and the two slots 21 are symmetrically distributed about the insertion rod 19. One end of the stopper 43 is inserted into the slot 21, and the height of the stopper 43 is equal to the height of the slot 21. The stopper 43 is in the shape of a "concave" character. A rubber support plate 22 is fixed in the groove body of the stopper 43, and one end of the rubber support plate 22 is fixed inside the slot 21. The surface of the stopper 43 is provided with an inclined surface, and a blocking cover 23 is sleeved in the mounting groove 20; a spring 32 is sleeved on the rod body of the insertion rod 19, and the spring 32 is sleeved on the rod body of the insertion rod 19.

The outer diameter of the blocking cover 23 is smaller than the rod diameter of the insertion rod 19. After the insertion rod 19 passes through the corresponding bolt hole 12, the finger is picked in the picking groove 24. The picking groove 24 is an annular groove. The picking groove 24 is opened on the outer ring surface of the blocking cover 23. The blocking cover 23 is pushed back. After the blocking cover 23 and the block 43 are misaligned, the rubber support plate 22 rebounds to support the block 43 to pop out of the insertion rod. The groove 21 is a certain distance, and then the through hole 29 on the surface of the connecting piece 28 is sleeved on the screw rod 30, and then the nut 31 is screwed on the rod body of the screw rod 30 and locked. One end of the spring 32 is pre-welded to the surface of the flange 10, and one end of the rubber sleeve 33 is pre-bonded to the surface of the flange 10. When the core tube 2 slides along the outer sleeve 1, the flange 11 slides along the multiple plug rods 19, and the flange 11 tensions the spring 32 and the rubber sleeve 33 to produce elastic deformation. The stopper 43 is used to block the flange 11, that is, cooperate with the retaining ring 4 and the rubber connecting tube 5 to realize the maximum telescopic distance limit of the outer sleeve 1, thereby preventing the core tube 2 from being withdrawn from the outer sleeve 1.

[0028] A flexible waterproof cover 35 is provided on the surface of the flange 2 11. After the flexible waterproof cover 35 is unfolded, it protects the flange 10 and the flange 2 11. A protective ring 36 is threadedly sleeved on the tube body of the outer jacket 1. One end of the protective ring 36 clamps the flexible waterproof cover 35. The other end of the protective ring 36 is rotatably connected to a plurality of support plates 39. One end of the support plate 39 is against the outer wall of the core tube 2. A receiving groove 34 is provided on the surface of the flange 2 11. The receiving groove 34 is an annular groove with an "L"-shaped fracture. One end of the flexible waterproof cover 35 is fixed to the inner wall of the receiving groove 34. The other end of the flexible waterproof cover 35 is fixed with an elastic band.

Install the block 43 in the installation groove 20 of the plug rod 19 to ensure that the block can move flexibly. Move the baffle 23 and squeeze the block 43 into the slot 21 along the inclined surface. At the same time, the rubber support plate 22 is squeezed and deformed. When the introduction ring 26 and the rubber clamp ring 27 are inserted into the slot 25, the baffle 23 is limited. Install the spring 32 between the flange 10 and the flange 2 11 to ensure that both ends of the spring are firmly fixed. The connecting piece 28 is sleeved on the spring 32, and the connecting piece is fixed on the flange 2 11 using the screw 2 30 and the nut 2 31. Ensure that the rubber sleeve 33 is sleeved on the outside of the spring 32, and one end is fixed on the surface of the baffle ring 4. Manually push the core tube 2 to slide inside the outer jacket 1, and check whether the sliding is smooth and there is no jamming. Check the sealing performance of the sealing ring and the rubber connecting tube to ensure that there is no leakage. Pull the flexible waterproof cover 35 out of the storage groove 34, bypass the flange two 11 and the flange one 10, and then put it on the outer jacket 1. Make sure that one end of the flexible waterproof cover 35 is clamped by the protective ring 36, and the other end is sleeved on the tube body of the outer jacket 1 through an elastic band. Turn the protective ring 36 and screw it with the outer jacket 1 until the inner ring end of the protective ring 36 clamps the flexible waterproof cover 35. Move the support plate 39 to rotate outward 270 degrees with the limit shaft 38 as the center, and support it between the core tube 2 and the protective ring 36. Make sure that the card slot three 40 at the end of the support plate 39 is buckled on the rubber ring 41 to prevent the support plate from swinging at will. Check whether all fasteners are loose and ensure that all connection parts are firm and reliable. Confirm whether the flexible waterproof cover 35 and the protective ring 36 are installed in place to ensure the protective effect. Manually push the core tube 2 to slide in the outer sleeve 1 again to verify the smoothness of sliding and the sealing performance. Confirm whether the support plate 39 and the protective ring 36 are stable and can resist the lateral thrust. The outer tube 1 is welded on one conveying tube and the core tube 2 is welded on another conveying tube.
