Embodiment Construction
[0019] Such as figure 1 and figure 2 As shown, the pipeline equipped with a protective tube, the pipeline (100) in the embodiment has the following structure, that is, it is mainly composed of a protective tube (101) and an inner tube (102). The inner pipe (102) has a water channel (104) through which the liquid flows, and the inner pipe (102) is fixed inside the protective pipe (101) through a support body (103).
[0020] Protective tube (101), inner tube (102) and support body (103) can be made of metal, but preferably with synthetic resin material. Compared with metal, synthetic resin materials are easier to process, can reduce the cost of consumables, and have good cushioning and heat preservation properties.
[0021] In order to make the protection pipe (101) buried underground have effective earth pressure resistance and impact resistance, its cross section can be made into a circle.
[0022] Such as figure 1 and figure 2 As shown, an inner tube (102) is provided ...

The invention discloses a pipeline with a protecting pipe and mainly solves the technical problems that the noise of the conventional water supply and drainage pipelines is high, the water flow is not smooth due to the accumulation of dirt, and the pipeline is easy to frost-crack in winter and is easy to rupture under pressure or external strong impact. The pipeline comprises the protecting pipe, wherein the protecting pipe is cylindrical, and an inner pipe is arranged in the protecting pipe; the cross-section of the inner pipe has an elliptical or oval shape of which the longitudinal inner diameter is greater than the transverse inner diameter; radial bulges are arranged outside the inner pipe and are taken as supporting bodies; and ends of the supporting bodies are fixed in the protecting pipe so as to ensure that the inner pipe is fixed in the protecting pipe and is longitudinally positioned in a vertical direction, and space parts are formed by the supporting bodies between the inner pipe and the protecting pipe. The pipeline has a reasonable structure, can reduce the noise during water drainage and ensure that drained water flows smoothly, and can prevent liquid from leaking outwards when the pipeline is damaged. The space parts are formed in the pipeline, so the pipeline has good heat preservation performance, and the rupture of the pipeline which is caused by the freezing of the liquid in the pipeline can also be prevented even in winter.
Description
technical field [0001] The invention relates to a pipeline equipped with a protective pipe, which is mainly used for various water supply or drainage, and belongs to the technical field of construction pipe material manufacturing and application. Background technique [0002] Households, factories and farms generally install various pipes for supplying water or discharging sewage. In the past, pipes were made of synthetic resin or metal, and were made into a cylindrical shape, which was a single closed pipe with liquid flowing inside. These pipelines usually have the problems of the external transmission of the noise of the liquid flowing inside the pipeline and the problems of rupture due to the freezing of the liquid inside the pipeline in winter. Especially for the upper water pipe, since the water inside flows at high pressure and high speed, noise will be generated along with the flow of water. And the downpipe, which is mixed with sewage and all kinds of dirt inside,...
