Embodiment Construction

[0012] A collar-reduced rubber hose, see figure 1 , which includes a rubber pipe 1 and flanges 2 arranged at both ends of the rubber pipe. The rubber pipe 1 includes an inner lining layer 3 , a reinforcing layer 4 and an outer covering layer 5 from the inside to the outside. The inner liner is laid on the entire pipeline including the connector part. Rubber hose inner lining layer 3, rubber material of outer coating layer 5 and fiber material of reinforcement layer 4 extend along the circumferential direction and vertical direction at both ends of the rubber hose, and form flange 2 together with several ring-shaped metal sheets 6, one end method The flange has a rotatable flange 7. The lining layer 3 contains a plurality of wear-resistant rings 32 made of alloy steel embedded in the rubber material 31 .

[0013] The lumen of the invention increases or decreases from one end to the other end, and is tapered. The wear-resistant ring made of alloy steel buried in the inner li...

Abstract

The invention discloses a ring-inlaid reducing rubber hose. The ring-inlaid reducing rubber hose comprises a set of rubber pipeline and flanges arranged at the two ends of the rubber pipeline. The rubber pipeline comprises a liner layer, a reinforcing layer and an outer covering layer from inside to outside, wherein the reinforcing layer is wound around the liner layer, and the outer covering layer is attached to the outer side of the reinforcing layer. The liner layer is composed of sizing materials and a wearing ring inlaid in the sizing materials and made of alloy steel products. The rubber pipeline is a taper with the diameter gradually decreasing from one end to the other end. The numbers of flange threaded holes in the two ends of the hose, the center circle diameter of each threaded hole and the hole diameter of each threaded hole are different and are consistent with the pipeline flanges connected with the hose respectively, and the flange at one end is provided with a rotary flange disc. The ring-inlaid reducing rubber hose is suitable for enabling pipelines with different diameters to be connected.

Description

technical field [0001] The invention relates to a rubber hose, in particular to a rubber hose with collar-reduced diameter used for connecting pipes with different diameters. Background technique [0002] In marine construction in recent years, the construction site is generally far away from the coastline, the transmission pipeline is generally long, and the conductor generally contains large particles of hard materials such as rocks, corals, etc. Therefore, this kind of transmission pipeline is generally composed of embedded rubber hoses . [0003] In offshore construction, sometimes due to the extension of the pipeline or the damage of the pipeline caused by the typhoon, the length of the hose pipeline of a certain caliber is not enough, and purchasing a batch of new hoses to supplement it requires not only a long production cycle, but also a long transportation process. What's more, the cost of the collar rubber hose is very high. In order to ensure the normal progres...
