An anti-leakage device for sewage treatment pump pipeline connection

Abstract

The invention discloses an anti-leakage device for pipeline connection of a sewage treatment pump, which belongs to the technical field of pipeline connection. They are connected through the installation box, the left and right sides of the installation box are connected with the clamping tube, the outer surface of the first connecting pipe and the second connecting tube are slidingly connected with the inner surface of the clamping tube, the present invention uses the first The cooperation between the first clamp and the second clamp clamps and fixes the connecting sleeve, improves the fastness of the connection between the connecting sleeve and the first connecting pipe and the second connecting pipe, and effectively avoids the phenomenon that the pipeline pressure changes. In the case of sewage leakage, to ensure the safe transportation of sewage, the use of tapered sleeves can not only ensure the tightness of the connection between the first connecting pipe and the second connecting pipe and the clamping tube, but also make the clamping tube adaptable to different sizes of the first connecting tube. A connecting pipe and a second connecting pipe.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection, and more specifically relates to a pipeline connection leakage prevention device for sewage treatment pumps. Background technique [0002] Sewage treatment pump series products are specially designed for conveying medium with certain corrosiveness and containing fine particles or crystallization. They are manufactured by steel-lined ultra-high molecular weight polyethylene molding process, which has excellent corrosion resistance and excellent wear resistance. , the structure is designed as a cantilever front opening type, and the impeller is semi-open type (no front cover plate), which enhances the passage in the flow channel, so that the particles and impurities in the medium can quickly pass through the pump chamber without clogging, and the shaft seal is K Type fluororubber sealing ring with cooling water jacket, taking into account the dual requirements of corrosion resistance an...

AI Technical Summary

Problems solved by technology

[0004] Existing pipeline connections are generally connected by pipe joints. The pipe joints generally use cylindrical pipe sections, and the two ends are respectively connected to the ends of the two pipes, or inserted into the ends of the two pipes for fixing. Simply insert the two pipes into the circular pipe. In the cylindrical pipe section, it is fixed by friction force, and the fixation is not fast enough. Once it is subjected to a large pressure change, it is easy to cause sewage leakage, and even cause the two pipes to directly separate from the cylindrical pipe section.
