Description

Polypropylene ventilation pipe

Technical Field

The utility model relates to an air pipe, more specifically say, it relates to a polypropylene ventilation pipe.

Background

The ventilation pipe is applied to dust collection of large power plants, anti-vibration and abrasion-resistant solids of coal mine enterprises and the like, such as dust, powder gas and corrosive gas, and dust removal and suction type plants. The common ventilation pipe adopts plastic bar plastic pipe, steel wire bar metal foil wall pipe and the like, and the ventilation pipe has poor high temperature resistance and poor elasticity.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art existence, the utility model aims to provide a polypropylene ventilation pipe that high temperature resistant and elasticity are good.

In order to achieve the above purpose, the utility model provides a following technical scheme:

polypropylene ventilation pipe, including the body, the body fuses by strip spiral winding and constitutes and the strip forms a plurality of connecting portion of evenly arranging in proper order, connecting portion are by the first connector that connects gradually, midbody and second connector constitute, first connector is a word form, the midbody is the U form, the second connector is "￢" form, second connector and midbody form the spread groove, the U form inslot of another connecting portion second connector is stretched into to the end of buckling of a connecting portion second connector in two adjacent connecting portions, the first connector of another connecting portion is arranged in the spread groove of a connecting portion.

Further, the pipe body is made of polypropylene materials, and a vacuum aluminum-plated layer is arranged on the outer wall of the pipe body.

Further, the pipe body is internally provided with a spring which is coaxial with the pipe body, and the spring is embedded in the U-shaped groove of the second connector.

Further, the fixing piece is arranged in the pipe body and arranged in the U-shaped groove, the cross section of the fixing piece is splayed, and the spring is embedded in the fixing piece.

By adopting the technical scheme, the beneficial effects of the utility model are that: the pipe body is high in strength, high in strength and good in elasticity, and meets the requirement for higher working strength, and the service life of the pipe body is greatly prolonged.

Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 2.

A polypropylene vent pipe with high temperature resistance and good elasticity.

The utility model discloses a concrete implementation scheme: including the body, the body fuses by strip spiral winding and constitutes and the strip forms a plurality of connecting portion 1 of evenly arranging in proper order, connecting portion 1 is by the first connector 2 that connects gradually, midbody 3 and second connector 4 constitute, first connector 2 is a style of calligraphy form, midbody 3 is the U form, second connector 4 is "￢" form, second connector 4 and midbody 3 form spread groove 5, the end of buckling of 1 second connector 4 of a connecting portion 1 in two adjacent connecting portions 1 stretches into the U form inslot 401 of 1 second connector 4 of another connecting portion, another connecting portion 1 first connector 2 is arranged in the spread groove 5 of a connecting portion 1.

By the body that strip spiral winding fuses, 1 interconnect of two adjacent connecting portion for the intensity of body is higher, and makes body bending nature and elasticity better, can be applicable to multiple industrial environment, and intensity is higher, and its application scope is wider.

The body is the polypropylene material, is equipped with the vacuum aluminum coating layer on the outer wall of body, is equipped with spring 6 in the body, and spring 6 is coaxial with the body, and spring 6 inlays in U form groove 401 of second connector 4, is equipped with mounting 7 in the body, and U form groove 401 is arranged in to mounting 7, and mounting 7's cross-section is the splayed, and spring 6 inlays in mounting 7.

The outer wall of the pipe body is provided with the vacuum aluminum-plated layer, so that the pipe body is not easy to corrode, the service life of the pipe body is prolonged, and the pipe body is more attractive; the spring 6 is spirally wound and sequentially penetrates through the U-shaped grooves 401 of the connecting parts 1, so that the strength and the elastic force of the pipe body are further enhanced; the fixing piece 7 is used for fixing the spring 6, so that the spring 6 is ensured to be stably and firmly embedded in the pipe body, and the use stability of the pipe body is ensured.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
