Pipe fitting lining system and lining method thereof

Abstract

The invention relates to a pipe fitting lining system and a lining method thereof, and belongs to the field of pipe fitting equipment. In the prior art, due to that that a nodular cast iron pipe usually has ovality, the nodular cast iron pipe vibrates or bounces when rotating, consequently, cement mortar arranged on the inner wall of the nodular cast iron pipe in a lined manner is not uniform, andthe strength and corrosion resistance of a pipe fitting are reduced. The pipe fitting lining system comprises a lining machine, a press wheel and a distribution device. The press wheel is mounted onthe lining machine. The distribution device is located on one side of the lining machine. The pipe fitting is lifted through a lifting band for lining, the pipe fitting and the lifting band are flexibly connected, the ovality of the pipe fitting can be remedied, the pipe fitting is knocked through the press wheel, and the cement mortar in the pipe fitting can be lined more uniformly; and cement mortar in a stirring tank is stirred by a stirring paddle, and the cement mortar is prevented from being solidified.

Description

technical field [0001] The invention relates to a pipe fitting lining system and a lining method thereof, belonging to the field of pipe fitting equipment. Background technique [0002] Ductile iron pipes are often used in pipeline transportation. The inner wall of ductile iron pipes is generally lined with cement mortar. The purpose is to improve the strength and corrosion resistance of ductile cast iron pipes. On the wheel, the inner wall of the ductile iron pipe is lined with cement mortar, and then it is driven to rotate, but the ductile iron pipe often vibrates or jumps when it rotates due to its own ellipticity, resulting in the ductile iron pipe. The cement mortar lining the inner wall is uneven, which will reduce the strength and corrosion resistance of the pipe fittings. [0003] In view of this, a metal pipe cement mortar lining machine is disclosed in the patent document with application number 201310571500.6, which relates to the technical field of metal pipe ma...

AI Technical Summary

Problems solved by technology

The above comparison document is to place the pipe fittings on the supporting roller assembly to drive the pipe fittings to rotate for lining. Due to the ellipticity of the pipe fittings, when the supporting roller assembly is rotated, the pipe fittings will vibrate or jump, resulting in poor cement mortar lining on the inner wall of the ductile iron pipe. uniform
