Water-saving heating pipe

Abstract

The invention relates to a water-saving warming pipe which comprises an outer pipe; the axis of the outer pipe is provided with an inner pipe; the outer peripheral wall of the inner pipe is rotationally and symmetrically provided with supporting sheets; the external of each supporting sheet is wrapped with a regulation bag made of an elastic material; the two ends of each regulation bag are provided with flexible sealing films respectively; the edges of the sealing films, the regulation bags and the inner pipe are in sealing connection and form a sealed pipe barrel space; the pipe barrel spaceis provided with an air guide pipe; the end part of the air guide pipe extends into external air; the inner wall of each regulation bag is provided with a regulation strip; sensing strips made of a thermal expansion material are distributed in the inner pipe at an equal interval; one ends of the sensing strips are connected with traction wires respectively; and the traction wires are connected with the corresponding regulation strips after penetrating through the pipe wall of the inner pipe. By adopting the water-saving warming pipe, a water body residual in a warming pipe can be effectivelyreduced when water is not used, so that waste of water resources is reduced, and the waiting time for water consumption is shortened at the same time.

Description

technical field [0001] The invention relates to a water heater fitting, in particular to a hot water pipe. Background technique [0002] The water heater is a commonly used household appliance. The host of the water heater is often set in the kitchen, and is arranged to other rooms through the heating pipe and the cold pipe, so as to ensure that all rooms have hot water for use; For a long time, if no hot water is used for a period of time, the hot water remaining in the heating pipe will cool down naturally; when hot water is needed, the user needs to wait for the hot water that has been cooled by the heating pipe to be discharged before the hot water can be used again. It takes a long time, and the cold water discharged from the heating pipe will basically not be recycled, resulting in a certain waste of water resources; and currently there is no suitable method to save these precious water resources. Contents of the invention [0003] In view of the above problems, the...
