Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to a corrugated pipe with a reinforced structure. Background Art

[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters. Their main purpose is to be used as a measuring element of pressure measuring instruments to convert pressure into displacement or force. The wall of the bellows is thinner and the sensitivity is higher. The measuring range is from tens of Pa to tens of MPa. Its open end is fixed, the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase the elasticity.

[0003] At present, when metal bellows are used between pipelines for a long time, there are weak positions on the inner wall of the bellows. When high-pressure water flows into the bellows, the water flow easily impacts the weak positions of the bellows, making the weak positions of the bellows susceptible to the force of water pressure, which may lead to the phenomenon of tube rupture at the bellows, thereby shortening the service life of the bellows. For this reason, we propose a bellows with a reinforced structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a bellows with a reinforced structure, in which a groove is arranged in the tube body of the bellows body, and then the tube body of the protection tube mechanism is installed in the bellows body through the groove. When high-pressure water flow needs to be transported through the bellows body, the inner extension tube of the protection tube mechanism in the bellows body is buffered by the elastic structure when under pressure, thereby avoiding the weak position of the bellows body from being damaged by the impact of the water flow, ensuring the safe and long-term use of the bellows body, and can effectively solve the problems in the background technology.

An outer rotating hole is provided in the recessed groove below the inner rotating hole, and a hexagon socket bolt is screwed between the inner rotating hole and the outer rotating hole. A fixed groove for clamping the fixed plate is provided on the groove wall on the other side of the recessed groove away from the outer rotating hole.

[0007] Furthermore, the tapered ring body of the tapered tail ring gradually thickens in the inner connecting direction at the tail tube of the inner extension tube, and the ring body thickness of the tail end of the tapered tail ring is greater than the ring body thickness of the rubber ring;
