Problems solved by technology

However, when the diameter of the drainage pipe or outlet connected to the shunt well is large (such as the diameter of the pipe is above DN400), the diameter of the rubber sleeve cannot be large and the amount of deformation is large. At this time, the end of the rubber sleeve Under large deformation with the end of the outer shell, the end of the rubber sleeve slips out between the flange and the end of the outer shell, and the seal of the charging chamber is not good
Moreover, the structure of the outer casing generally adopts a rigid structure, but the pipeline installed with the flexible shutoff device is also invariable. The matching between the outer casing of the flexible shutoff device and the pipeline is not good, and the end of the outer casing is often connected to the end of the pipeline. The closure device cannot be installed in the pipeline, and it needs to occupy the end of the pipeline to install the installation well. When the size of the flexible closure device is larger, the required installation well will be larger, the amount of infrastructure construction will be large, and the construction efficiency will be high. Inconvenient, therefore, there is an urgent need for a flexible shut-off device that can solve the sealing problem and facilitate installation

Abstract

The invention discloses a rubber sleeve with a mounting structure and a pipeline for mounting the rubber sleeve. The rubber sleeve is provided with a through circulation channel; the rubber sleeve isof an integrated structure; at least one independent pressurizing cavity is formed in the rubber sleeve; the rubber sleeve is of the integrated structure; the at least one independent pressurizing cavity is formed in the rubber sleeve; the rubber sleeve at the position where each pressurizing cavity is located is provided with an outer rubber layer and an inner rubber layer; an inlet and outlet hole is formed in the outer rubber layer of each pressurizing cavity and is communicated with the pressurizing cavity; the mounting structure comprises two limiting parts; and the two limiting parts arefixed to the two ends of the rubber sleeve to clamp the rubber sleeve. According to the rubber sleeve with the mounting structure and the pipeline for mounting the rubber sleeve, the rubber sleeve isclamped and fixed through the limiting parts arranged at the two ends of the rubber sleeve, and when the rubber sleeve is installed and maintained in the later period, only the limiting parts at thetwo ends need to be detached, so that the installation and the maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of drainage equipment, in particular to a rubber sleeve with a mounting structure and a pipe for installing the sleeve. Background technique [0002] The flexible shutoff device is a kind of shutoff facility applied to the water outlet or outlet of the diversion well. Its structure generally includes an outer shell and a rubber sleeve. A pressurized cavity is formed between the outer shell and the rubber sleeve. The end of the rubber sleeve The upper part and the end of the outer shell are sealed and connected by a flange. When the pressurized gas is filled into the pressurized cavity, the rubber sleeve is relatively inwardly deformed, the inner wall of the rubber sleeve is attached, and the circulation channel is closed. However, when the diameter of the drainage pipe or outlet connected to the shunt well is large (such as the pipe diameter is above DN400), the diameter of the rubber sleeve cannot be large ...
