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 an embedded ring variable-diameter rubber hose for connecting pipes with different diameters. Background technique

[0002] In recent years of marine construction, the construction site is generally far from the coastline, and the transportation pipeline is generally longer. The transportation generally contains large particles of hard materials such as rocks and corals. Therefore, this kind of transportation pipeline is generally composed of ring rubber hoses. .

[0003] In offshore construction, sometimes due to pipeline lengthening or pipeline damage caused by typhoons, the length of certain diameter hoses is not enough, and purchasing a batch of new hoses to supplement, not only requires a long production cycle, but also a long transportation process. More importantly, the cost of the embedded rubber hose is very high. In order to ensure the normal progress of construction, the easiest and most f...
