The invention provides a pipeline
stain remover, which consists of a first sealing leather cup, a second sealing leather cup, a third sealing leather cup, a
stain removing wheel and a first elastic shaft, or a second elastic shaft, or a third elastic shaft, or a fourth elastic shaft, or a fifth elastic shaft, or a seventh elastic shaft. Compared with the prior art, the pipeline strain remover has the advantages that when the pipeline strain remover passes through a pipeline
elbow, the self elastic shaft can naturally bend to turn along with the
elbow, and after the pipeline strain remover passes through the pipeline
elbow, through the self memory function, the working of immediately doing parallel movement to the pipeline axial line is realized, so that the undamaged completeness and the normal operation of the pipeline
stain remover are protected, the service life of the pipeline
stain remover is greatly prolonged, meanwhile, the pipeline
stain remover is positioned at the elbow turning part, the pipeline
stain remover can maintain the original state, the sealing performance is good, the air leakage is avoided, the resources are saved, the operation speed of the pipeline stain remover is uniform, the service life of the pipeline stain remover is prolonged, the scale removing cleaning efficiency is greatly improved, and the integral benefits are very obvious.
