Environment-friendly sealing sleeve for hough nodes

Abstract

The invention discloses an environment-friendly sealing sleeve for hough nodes. The sealing sleeve comprises two half sealing glue sleeve bodies, wherein each half sealing glue sleeve body consists of semicircular sealing strips positioned on two ends and sealing side strips positioned on two sides, a sleeve body with a circular arc surface is arranged between the semicircular sealing strips and the sealing side strips, and latticed ribs are distributed on the outer wall of the sleeve body. According to the environment-friendly sealing sleeve, the semicircular sealing strips and the sleeve body are directly adhered and matched with the outer wall of a coated pipeline, therefore, the damaged part of the pipeline can be plugged directly so as to enable water in the pipeline not to flow out of the pipeline, a space of accumulated water cannot be reserved inside the inner cavity of the hough node and outside the half sealing sleeve body, the backflow of the accumulated water breeding bacteria polluting the water quality due to the transportation stopping and pressure loss of the pipeline does not exist, and the accumulated water phenomena in a containing cavity of the hough nodes can be decreased, and even eliminated.

Description

technical field [0001] The invention relates to a half-type quick joint for pipelines, especially a half-type quick joint for tap water pipelines. Background technique [0002] As we all know, there are cast iron pipes and cement pipes in the main pipelines for transporting tap water. Among them, ductile iron pipes are the most common, and most of the pipes are laid underground. These pipes are often damaged, broken, and leaked due to various reasons. The Huff-type quick connector in the prior art consists of two castings, a set of rubber parts and bolts to form a product, and two semi-circular Huff-type quick connectors are used for emergency repairs to accommodate the damaged part of the pipeline in the inner compartment of the Huff joint Inside, use the bolts to tighten the rubber seals on the half-circle joints of the Huff to seal the leakage. This method has been recognized by the water supply industry and is widely used in pipeline emergency repairs due to the small n...

Problems solved by technology

This accumulated water 5 cannot flow when there is pressure inside the pipeline 1. In fact, it becomes a cavity of stagnant water. Because there is no sanitary coating on the outer wall of the pipeline 1, and there is no sanitary coating on the inner wall of the half section 2, it is left inside. The accumulated water 5 in the cavity has been exposed to metal corrosion and bacteria for a long time. If the other parts of the pipeline 1 are damaged or the maintenance stops and the pressure is lost, because the inner cavity of the damaged half joint is connected with the inside of the pipeline, it will stay in the half joint at this time. The accumulated water 5 in the cavity will flow back into the pipeline 1 and pollute the water quality
