Abstract

The utility model discloses a reducing sleeve for a pump. The reducing sleeve comprises a fixed seat and a tubular column, wherein the fixed seat is provided with a threaded hole and a through hole; one end of the tubular column is arranged on the fixed seat, an inner hole of the tubular column is communicated with the through hole of the fixed seat, and screw threads are arranged in the inner hole on the other end of the tubular column; and an outer wall of the tubular column is of a wave shape, and a fixed block is arranged on the outer wall of the tubular column. By adopting the scheme, the reducing sleeve has the advantages of simplicity in assembly, excellent sealing performance, high strength, easiness in dismantling, a wide application scope and low cost.

Description

A kind of pump reducing sleeve

Technical field

The utility model relates to the reducing sleeve field, particularly relates to a kind of pump reducing sleeve.

Background technique

Pump is the class major product in the mechanical industry as a kind of universal machine, and pump and valve all are commonly employed in chemical industry, mining industry, metallurgical industry, agricultural, food processing, power department, national defense construction.Usually need reducing sleeve to be connected and fixed between the body of pump and the pipeline, existing reducing sleeve sealing is poor, and installation difficulty is big, and is fragile.

The model utility content

The technical problem that the utility model mainly solves provides a kind of pump reducing sleeve, simple installation, and good airproof performance, the intensity height is easy to dismounting, and applied widely, cost is low.

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of pump reducing sleeve is provided, comprises: fixed base and tubing string, and described fixed base is provided with tapped hole and through hole; Described tubing string one end is arranged on the fixed base, and the through hole UNICOM of tubing string endoporus and fixed base is provided with screw thread at the endoporus of the tubing string the other end; Described tubing string outer wall undulate is provided with fixed block at the tubing string outer wall.

The beneficial effects of the utility model are: the utility model simple installation, and good airproof performance, the intensity height, applied widely.
