Positioning sleeve with adjustable pipe diameter for producing polyethylene water-supply pipes

Abstract

The invention discloses a positioning sleeve with adjustable pipe diameter for producing polyethylene water-supply pipes. The positioning sleeve comprises a splicing pipe, wherein a pair of positioning grooves are formed in an outer wall of the splicing pipe; one end of the splicing pipe is connected with a hose; the tail end of the hose is connected with a sealing pipe; a plurality of sealing screw holes are formed in the cross section of a pipe wall of a sealing pipe; a first adjusting ring and a second adjusting ring are connected to the outer part of an outer wall of the hose in a sleevingmanner; a plurality of control knots are respectively arranged on the first adjusting ring and the second adjusting ring; the control knots are connected with each other through adjusting screw rods;the adjusting screw rods are rotated so as to control the loosening of the adjusting rings. The positioning sleeve with the adjustable pipe diameter for producing the polyethylene water-supply pipesdisclosed by the invention integrally has a structure of two pipe clips and one pipe, the splicing pipe and the sealing pipe arranged at the two ends of the positioning sleeve are of fixed connectionpipes, and the hose positioned between the splicing pipe and the sealing pipe is elastic and can be retractable; by adjusting the adjusting rings arranged outside the hose, adjustment of caliber of ring bodies can be realized, so that the positioning sleeve can adapt to the pipes with different sizes, frequent replacement is avoided, and the production cost is also reduced.

Description

technical field [0001] The invention relates to a positioning sleeve with adjustable pipe diameter for the production of polyethylene water supply pipes. Background technique [0002] Polyethylene (PE) material is widely used in the field of water supply pipe manufacturing due to its high strength, corrosion resistance and non-toxicity. Because it will not rust, it is an ideal pipe to replace ordinary iron water supply pipes. my country's plastic pipes are developing rapidly, and the quality is constantly improving. Among them, polyethylene PE pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas pipelines, electrical and telecommunications protection casings, industrial pipes, agricultural pipes, etc. due to their unique advantages. It is mainly used in urban water supply, urban gas supply and farmland irrigation and other fields. Positioning sleeves are used in the production process of polyethylene water suppl...

AI Technical Summary

Problems solved by technology

Positioning sleeves are used in the production process of polyethylene water supply pipes, but the diameter of the commonly used positioning sleeves cannot be adjusted at present. Different positioning sleeves need to be replaced to produce polyethylene water supply pipes with different diameters, which also increases the trouble of operation. input cost
