Problems solved by technology

In the actual use process, factors such as displacement, deformation and misalignment inevitably occur in the pipeline system during operation, and the flexible rubber joints are squeezed tightly. However, the strength of the existing rubber joints is insufficient, and the excessive expansion and contraction often cause the rubber Internal damage affects its service life

Embodiment 1

[0012] Embodiment 1: see figure 1 and figure 2 , a rubber pipe joint with helical stiffening. There are three spiral grooves in the middle of the rubber pipe, and a helical spring is matched in each groove.

[0013] The rubber tube includes a skeleton layer 3 in the center and rubber layers on both sides, namely an inner rubber layer 1 and an outer rubber layer 2 .

[0014] In addition, the two ends of the rubber tube are respectively straight pipe sections 6, and the mouth of the straight pipe section 6 is provided with a flange-shaped flange 7 outward, and the edge of the flange-shaped flange 7 is provided with a fixing hole. The inner sides of the flanges 7 are fitted with an annular flange 5 , which is matched with the flange-shaped flanges 7 , and the fixing holes 8 of the flange-shaped flanges 7 correspond to the fixing holes of the ring flanges.

Embodiment 2

[0015] Embodiment 2: The drawings are not drawn, and the content is basically the same as that of Embodiment 1. The difference is that in this embodiment, a double-helical groove is provided on the outside of the rubber tube and a double-helical spring is matched with it.

Abstract

The invention discloses a joint with a spirally-reinforcing rubber pipe. Spiral grooves are formed in the middle of the rubber pipe, and a spiral spring is mounted in each spiral groove in a matched and sleeved manner. The joint has the advantages of simple structure and high strength; through the spiral springs, radial expansion amplitude of the rubber joint can be constrained, and traction and compression resisting effects on the axial direction of the rubber joint can be realized to achieve good axial compensation effect, so that pressure bearing capacity can be improved, and service life can be prolonged; the rubber joint and flanges are fully fitted and fixed together, so that sealing strength when the rubber joint is connected with a pipeline can be improved, and end structure of the rubber pipe is simplified.

Description

technical field [0001] The invention relates to the technical field of pipeline telescopic compensators, in particular to a rubber pipe joint with spiral reinforcement. Background technique [0002] Flexible rubber joints are widely used in pipeline connections to compensate for the linear expansion and contraction of pipelines due to temperature changes, eliminate vibration and noise transmission, and also play a good role in the protection of pipelines and equipment. In the actual use process, factors such as displacement, deformation and misalignment inevitably occur in the pipeline system during operation, and the flexible rubber joints are squeezed tightly. However, the strength of the existing rubber joints is insufficient, and the excessive expansion and contraction often cause the rubber Internal damage affects its service life. Contents of the invention [0003] Aiming at the problems and deficiencies in the prior art, the invention provides a rubber pipe joint w...
