Clearing mechanism used for scale substances of inner circumferential wall of pipefitting

Abstract

The invention discloses a clearing mechanism used for scale substances of the inner circumferential wall of a pipefitting. The mechanism comprises a cylinder, a rotating shaft, an end cover and a base; the base is in threaded connection with the lower end of the cylinder, a screw is fixed to the middle of the upper surface of the base, the rotating shaft movably penetrates the middle of the end cover and then extends downwards, a screw matched with the screw is formed in the lower end face of the rotating shaft in the axis direction of the rotating shaft, a plurality of arc cutting blades are arranged on the rotating shaft, multiple adjusting holes are formed in the outer circumferential wall of the cylinder, the cutting blades penetrate the adjusting holes to extend outwards, and a limiting block is arranged on the inner circumferential wall of the cylinder. When the angle of the cutting blades is adjusted to the maximum degree, the arc outer side lines of the cutting blades make contact with the side walls of the adjusting holes, the arc concave face of the limiting block also makes contact with the arc outer side walls of the cutting blades, supporting stability of the cutting blades in the use process is reinforced, impact to the cutting blades due to action and reaction borne by the cutting blades is avoided, and the possibility of cutting blade stress breaking is reduced.

Description

technical field [0001] The invention relates to maintenance equipment for pipe fittings, in particular to a mechanism for cleaning dirt on the inner circumference of pipe fittings. Background technique [0002] Pressure piping refers to all piping subjected to internal or external pressure, regardless of the medium in the pipe. The pressure pipeline is a part of the pipeline. The pipeline is used to convey, distribute, mix, separate, discharge, measure, control and stop fluid flow. It consists of pipes, fittings, flanges, bolted connections, gaskets, valves, and other components. Or the assembly assembly composed of pressure parts and supporting parts; the pressure pipe is a system, which is related to each other and affects the whole body. The length-diameter ratio of the pressure pipe is large, and it is easy to lose stability. More complex. The fluid flow state in the pressure pipeline is complex, the buffer space is small, and the frequency of changing working conditio...

AI Technical Summary

Problems solved by technology

In the process of use, the inner wall of the pipeline will produce a certain amount of scaling, which will reduce the flow rate of the fluid in the pipe and reduce the transmission efficiency of the pipeline; In order to prevent damage to the smoothness of the inner wall of the pipeline, the dirt removal equipment does not clean the dirt on the inner wall thoroughly
