Abstract

The utility model belongs to a design of a PE double-walled flexible corrugated pipe, wherein the inner wall of the PE double-walled corrugated pipe is designed into a concave-convex corrugated shape; the wave crest part of the outer wall of the double-walled corrugated pipe is an arc shape adopting arc transition angle for transition; the wave crest part and the transition angle are arc-shaped; as the inner wall adopts arc transition and the outer wall is uniform in thickness, the external force shock resistance of the PE double-walled flexible corrugated pipe is greatly improved; and as the inner wall adopts the arc transition, the transition angle is smooth and even and the air flowing is smooth, at the same time the corrugated structure of the inner wall enables the bending of the pipeline to be smoother within the range of 90 DEG, and the construction is more convenient. The PE double-walled flexible corrugated pipe has a long service life up to more than 50 years without being exposed to ultraviolet rays, resists the corrosion of all chemical media, and is optimum in preventing the metal galvanized pipe from being perforated due to corrosion.

Description

A kind of PE double-walled flexible bellow
Technical field
The utility model belongs to a kind of design of PE double-walled flexible bellow.
Background technique
PE double-walled flexible bellow is mainly used in gas supply pipe line and artificial coal gas conversion rock gas improvement project; The double-walled flexible bellow can fundamentally solve the corrosion failure problem of combustion gas metal inlet tube, and the combustion gas improvement project is to involve huge numbers of families' engineering.The reforming technology conventional method is that the replacing pipeline is digged pit stemming operation.Wasteful, destroy environment, destroy road.Chinese patent ZL 01244996.2 discloses a kind of " both arms bellows ", but this inner tube wall is a smooth flat.
The model utility content
The purpose of the utility model is a kind of PE double-walled flexible bellow of design.
Transform gas supply pipe line and artificial coal gas conversion rock gas improvement project with PE double-walled flexible bellow for separating by no means excavation, adopt in the pipe, manage outer wall and be the lenticular ripple struction of ripple and design.
The utility model is designed to lenticular corrugated with the inwall of PE double-wall corrugated pipe; The crest position of double-wall corrugated pipe outer wall is the circular shape by circular arc transition angle transition; Crest position and transition angle integral body are circular shape; Inwall is by the circular arc transition, and this lenticular corrugated is to accomplish through double-walled flexible bellow production line.Production technology is prior art, does not do the more description more.
Description of drawings
Accompanying drawing 1 is the schematic representation of PE double-wall corrugated pipe
The outer wall of 1 double-wall corrugated pipe among the figure, the inwall of 2 double-wall corrugated pipes
Specific embodiments
The embodiment of the utility model combines accompanying drawing to be described below, the outer wall of PE double-wall corrugated pipe (1), the inwall of PE double-wall corrugated pipe (2); All adopt corrugated structure; The crest position of double-wall corrugated pipe outer wall is the circular shape by circular arc transition angle transition, and crest position and transition angle integral body are circular shape, and inwall adopts the circular arc transition; The outer wall wall thickness is even, has strengthened the ability that its external force resistance impacts greatly; Inwall is owing to adopt the circular arc transition, and its transition angle slyness is smooth, does not have in " turning " production process formula, and gas flow is smooth and easy, and the ripple struction of inwall can make pipe bending more smooth and easy simultaneously, can do 90 ° of bendings, and it is more convenient to construct.PE double-walled flexible bellow is characterized in; The inwall of pipe is a hollow bowl; The outer wall of pipe is axial ripple struction, between boss and the inwall cavity is arranged, thereby formation ripple depression position and inwall fuse into one; The lenticular ring stiffener of ripple, the one, improved the shaping strength and the join strength of bellows; The 2nd, improved the water conservancy diversion amount and the water conservancy diversion speed of bellows effectively.
The bellows-shaped unanimity attractive in appearance of PE double-walled flexible bellow, outer wall adopts the helical corrugation formula, and spiral inner wall is corrugated, causes pliability good.Under the condition that equates load, the double-walled flexible bellow needs certain thickness tube wall just can meet the demands.Therefore, and compare, can practice thrift the raw material about half, so double-walled flexible bellow cost is lower with the solid wall pipe of material same specification.Product weight is light, carrying with is connected all easily, engineering cost is low, operating expenses province.Quick construction, maintenance work are simple.Under the situation of and execution conditions difference tight in the duration, its advantage is more obvious.Long service life, the erosion of anti-various chemical mediators is not receiving under the UV sunlight condition, and can reach more than 50 years the service life of double-walled flexible bellow, is the optimum scheme that solves metal-plated zinc pipe corrosion failure.

Claims (2)

1. a PE double-walled flexible bellow is characterized in that inwall is designed to lenticular corrugated, and the crest position of double-wall corrugated pipe outer wall is the circular shape by circular arc transition angle transition, and crest position and transition angle integral body are circular shape.
2. PE double-walled flexible bellow as claimed in claim 1 is characterized in that inwall is by the circular arc transition.
