an effective heat-insulating hot water conveying pipeline comprises an inner fluid pipe and an outer sleeve, wherein the inner fluid pipe is sleeved in the outer sleeve; the both ends of outer tube all are equipped with the ring flange, the outer tube has set gradually heat preservation, vacuum layer and steel pipe layer from inside to outside, be equipped with seal valve and solar panel on the outer tube, the seal valve intercommunication the vacuum layer, solar panel intercommunication heating device, heating device locates in the interior fluid pipe.

Furthermore, the filler in the heat-insulating layer is heat-insulating cotton. The heat-insulating cotton has the advantages of low price, strong heat-insulating property, low price and high quality.

Furthermore, the outer side of the steel pipe layer is coated with an anti-corrosion layer. So set up, prevent that hot water conveying pipeline from suffering long-time earth wind from blowing the sunshine and corroding ageing.

Furthermore, the outer sleeve is also provided with a barometer, and the detection end of the barometer is connected with the vacuum layer. Whether the vacuum layer exists in a vacuum state or not is observed through the barometer, and the heat insulation effect of the vacuum layer is ensured.

Furthermore, an annular convex block is arranged on the outer side of the flange plate at one end of the outer sleeve, an annular groove matched with the annular convex block is arranged on the outer side of the flange plate at the other end of the outer sleeve, and rubber layers are arranged on the outer surfaces of the annular convex block and the annular groove. By the arrangement, the inner fluid pipes can be perfectly embedded with each other through the combined action of the annular convex block and the annular groove. Meanwhile, the rubber layer is arranged, and hot water is prevented from flowing out from the gap between the inner fluid pipes by the sealing layer of the rubber layer.

Compared with the prior art, the beneficial effects of the utility model are that:

in the vacuum layer, the heat insulation effect is achieved because the conduction of heat transfer carriers such as air does not exist. While the insulation also prevents heat loss in the inner fluid pipe. The two are combined to realize the reduction of heat loss.

And arranging a sealing valve in the vacuum layer, and pumping out air in the vacuum layer by using the sealing valve so that the vacuum layer is in a vacuum state.

Considering that heat loss still exists more or less in the hot water conveying process, the heating device is arranged in the inner fluid pipe, so that heating can be kept in the conveying process, and the heat reaching the target is guaranteed to be kept all the time. The heating device utilizes the solar panel to generate electricity, and is clean and environment-friendly.
