Rubber hose and manufacturing method

Abstract

The invention discloses a rubber hose and a manufacturing method thereof. The rubber hose comprises a hose section and flange plates arranged at two ends of the hose section, wherein the hose wall ofthe hose section comprises an inner rubber layer, a strengthening layer and an outer rubber layer, which are arranged sequentially from inside out; and ends of the strengthening layer are wound aroundspacing rings and embedded and fixed in mortises of the flange plates. According to the rubber hose provided by the invention, the inner rubber layer contacts an in-pipeline medium and ends of the inner rubber layer turn back to enclose the flange plates to be used for sealing; the strengthening layer performs a function of pressure bearing; the outer rubber layer plays a protective role; the flange plates are used for connection; and the spacing rings and the flange plates jointly fix the strengthening layer, so as to prevent the relative displacement between the strengthening layer and rubber during a deformation process, which can affect the capacity of pressure bearing. The rubber hose referred to in the invention is applied to the flexible connection of important pipelines passing through a seismic isolation layer, so as to protect the important equipment pipelines from damage during a deformation occurring in an earthquake; the rubber hose has the characteristics of strong deformation capacity with a maximum being up to + / -700 mm, small reaction force and good durability; and besides, the fatigue resistance for repeated deformation is excellent and the service life is long.

Description

technical field [0001] The invention relates to the technical field of building earthquake isolation, in particular to a pipeline structure in an earthquake isolation layer and a manufacturing method thereof. Background technique [0002] Building isolation technology is a new anti-seismic technology, which can effectively improve the anti-seismic ability of buildings. Building isolation technology is mainly to use isolation bearings in the isolation layer to reduce the damage of earthquakes to buildings, and isolation bearings have been widely used. However, the treatment of pipes, pipelines and other connecting parts passing through the isolation layer is generally poor, and the damage of important equipment and pipelines in the earthquake cannot be avoided, and the continuity of building functions after the earthquake cannot be guaranteed. Existing pressure-bearing rubber hoses are usually required to be non-deformable or difficult to deform, which does not meet the requ...
