Description

Flow adjustable PVC pipeline

Technical Field

The utility model relates to a plastics tubular product technical field, more specifically say, the utility model relates to a flow adjustable PVC pipeline.

Background

The water supply and drainage pipe is widely used in the water supply and drainage fields of highways, railway roadbeds, subway engineering, waste landfill sites, tunnels, green belts, playgrounds and the like, and underground irrigation and drainage systems of agriculture and horticulture. The existing metal water supply and drainage pipe is easy to corrode and rust, even causes serious problems of perforation, blockage and the like because the existing metal water supply and drainage pipe is buried underground for a long time. And the flow of the water-saving irrigation system is not adjustable, so that the problems of large occupied space, long irrigation time consumption and resource waste are often caused by improper pipeline size, and the normal use of people cannot be met.

Therefore, the development of a pipeline with adjustable flow is one of the problems to be solved by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

Not enough to prior art, the utility model provides a flow adjustable PVC pipeline has solved the PVC pipeline among the prior art and is not adjustable at the use flow, often because the improper problem of bringing occupation space big, irrigation length consuming time, wasting resource of pipeline size, has the advantage that the flow is adjustable, comprehensive properties is excellent.

(II) technical scheme

In order to achieve the above object, the utility model provides a following technical scheme: a flow-adjustable PVC pipeline comprises an outer pipe, an inner pipe and a flow dividing pipe, wherein the inner pipe is sleeved in the outer pipe, an elastic packing layer is arranged between the outer pipe and the inner pipe, and the flow dividing pipe is arranged on the wall of the outer pipe and is in penetrating connection with the outer pipe and the inner pipe; the flow limiting valve is arranged on the flow dividing pipe, and the flow of the flow dividing pipe can be adjusted through the flow limiting valve; the outer tube is hard PVC material, the shunt tubes are hard PVC material, the inner tube is soft PVC material, outer tube, elasticity packing layer and inner tube adopt extrusion technology in proper order each other hot melt adhesive backlog mix as an organic whole in the production forming process.

Further, the outer wall of the outer pipe is coated with a weather-resistant coating.

Further, the inner wall of the inner pipe is coated with a corrosion-resistant coating.

Furthermore, a spring is arranged in the elastic filler layer, and the elastic filler layer is made of a thermoplastic elastomer.

Preferably, the thermoplastic elastomer is thermoplastic elastomer SBS.

Further, the thickness of the elastic filler layer is 5-15 mm.

Further, the length of the PVC pipeline with the adjustable flow is 8-12 m.

(III) advantageous effects

The utility model provides an anticorrosive power pipeline. The method has the following beneficial effects: the PVC pipeline with adjustable flow solves the problems that the PVC pipeline in the prior art has non-adjustable flow in the use process, and the space occupation is large, the irrigation time consumption is long and the resources are wasted due to the improper size of the pipeline, and has the advantages of adjustable flow and excellent comprehensive performance; be equipped with the elastic packing layer between interior outer tube, can effectively avoid the flow too big according to flow control water pressure, the pipeline that water pressure too high leads to breaks to reduce pipeline life's problem.
