Description

Composite water-swelling rubber ring

Technical Field

The application relates to the technical field of rubber accessories, in particular to a composite water-swelling rubber ring.

Background

In order to replace the traditional drain pipe, a large number of plastic drain pipes with structural walls are emerged, corrugated pipes, ribbed pipes and steel belt winding pipes are common, wherein the steel belt winding pipes are the most reasonable and safe in structure. However, the production of the steel strip winding pipe adopts the processes of extrusion, winding and welding, so that the socket pipe can not be produced on line like other structural wall pipes produced by adopting the production process. Although the double-wall winding pipe is the most reasonable structural wall pipe, the connection mode restricts the popularization and application of the double-wall winding pipe. In the existing construction method, a heat-shrinkable rubber ring is generally adopted to connect the steel belt winding pipes, and the heat-shrinkable rubber ring needs to be baked by fire during construction, so that potential safety hazards are caused; the short heat-shrinkable rubber ring and the steel belt winding pipe are not tightly combined to cause water leakage, the long heat-shrinkable rubber ring is damaged due to the long baking time, the construction efficiency is low, and the construction quality is not guaranteed.

The composite water-swelling rubber ring comprises a rubber ring body, wherein an annular reinforcing plate is arranged inside the rubber ring body; spiral convex ribs are arranged at two ends of the inner ring surface of the rubber ring body; the convex ribs are made of water-swellable rubber and are arranged in a compounding manner with the rubber ring body; the section shape of the convex rib is matched with the outer wall of the steel belt winding pipe.

The above aspect and any possible implementation further provide an implementation in which the rib is provided with at least two turns.

The above aspects and any possible implementations further provide an implementation in which the inner diameter of the rubber ring body is greater than the maximum diameter of the outer wall of the steel strip wound pipe.

The above aspects and any possible implementation manner further provide an implementation manner, wherein the outer annular surface of the rubber ring body is provided with an anti-slip pattern.

Compared with the prior art, the beneficial effects of this application are:

the composite water-swellable rubber ring is provided with the rubber ring body, the annular reinforcing plate is arranged in the rubber ring body, the strength of the rubber ring body is improved, and the rubber ring body has enough strength when the pipeline has deviation due to the size and soil quality change in the later construction and use process; spiral convex ribs are compounded at two ends of the inner ring surface of the rubber ring body; the protruding muscle is for meeting water inflation rubber, and the cross sectional shape of protruding muscle and the outer wall phase-match of steel band winding pipe guarantee sealed effect, and it is convenient to install simultaneously, need not the fire and roast, improves the factor of safety of construction, masters the installation quality easily.
