Abstract
The invention discloses a reducing sleeve used for a pump. The reducing sleeve comprises a fixing base and a pipe column, wherein the fixing base is provided with a threaded hole and a through hole, one end of the pipe column is arranged on the fixing base, an inner hole of the pipe column is communicated with the through hole of the fixing base, an inner hole in the other end of the pipe column is provided with a thread, the outer wall of the pipe column is wave-shaped, and the outer wall of the pipe column is provided with a fixing block. Due to the mode, the reducing sleeve is easy and convenient to install, good in sealing performance, high in strength, easy to detach, wide in application range and low in cost.
Description
Technical field
The present invention relates to reducing sleeve field, particularly relate to a kind of pump reducing sleeve.
Background technique
Pump, as a kind of universal machine, is the class major product in mechanical industry, and pump and valve are all commonly employed in chemical industry, mining industry, metallurgical industry, agricultural, food processing, power department, national defense construction.Conventionally between the body of pump and pipeline, need reducing sleeve to be connected and fixed, existing reducing sleeve sealing is poor, and installation difficulty is large, fragile.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of pump reducing sleeve, simple installation, and good airproof performance, intensity is high, is easy to dismounting, and applied widely, cost is low.
For solving the problems of the technologies described above, the technological scheme that the present invention 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 fixed base, and the through hole UNICOM of tubing string endoporus and fixed base is provided with screw thread on the endoporus of the tubing string the other end; Described tubing string outer wall undulate is provided with fixed block on tubing string outer wall.
The invention has the beneficial effects as follows: simple installation of the present invention, good airproof performance, intensity is high, applied widely.
