Environment-friendly Hough joint

Abstract

The invention provides an environment-friendly Hough joint. By the adoption of the environment-friendly Hough joint, the waterlogging phenomenon in a containing cavity of the Hough joint is relieved or even eliminated. The environment-friendly Hough joint comprises a Hough type pipe joint composed of two half Hough joint bodies in an enclosed mode. The two half Hough joint bodies are each provided with a half sealing sleeve body. Each half sealing sleeve body is directly attached to the outer pipe wall of a wrapped pipeline in a matched mode. Filler is arranged in the space between the outer walls of the half sealing sleeve bodies and the inner walls of the two half Hough joint bodies. After the filler is arranged, the half sealing sleeve bodies are kept in the state that the half sealing sleeve bodies are closely attached to the outer pipe wall of the wrapped pipeline. Due to the fact that the filler is arranged in the space between the outer walls of the half sealing sleeve bodies and the inner walls of the half Hough joint bodies, a rubber plate is pressed by the filler to make contact with the damaged pipe wall firstly, the damaged portion is blocked, water in the pipeline is prevented from flowing out of the pipeline, at the moment, the space of waterlogging does not exist in an inner cavity of the Hough joint anymore except the filler and the rubber plate, and the situation that the pipeline is shut down and loses pressure, accumulated water with bacteria flows back, and accordingly the water is contaminated is avoided.

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 quick connector in the prior art consists of two castings, a set of rubber parts and bolts to form a product, and two half-round Huff quick connectors are used for emergency repairs to accommodate the damaged part of the pipeline in the Huff joint. In the bin, use the bolts to tighten the rubber seals on the joint surface of the Huff semi-circle 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 fact that it employs fewer people...

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
