In embodiments of the present invention, inner tube 20 one end be fixedly connected with the outer end of inner tube 20 through the outer silk interface of the outer silk threeway 41 of the first stainless steel and the inside and outside silk straight-through 51 of straight-through 51, the first stainless steels of the inside and outside silk of the first stainless steel successively and with inner tube 20 lumen therethrough; Inner tube 20 other ends be fixedly connected with the outer end of inner tube 20 through the outer silk interface of the outer silk threeway 42 of the second stainless steel and the inside and outside silk straight-through 52 of straight-through 52, the second stainless steels of the inside and outside silk of the second stainless steel successively and with inner tube 20 lumen therethrough.
In embodiments of the present invention, inner tube 20 is 304 corrugated stainless steel tubings; Outer tube 10 is PPR hot-water line, and the pipe range of outer tube 10 is 6 meters.
The operation principle of the embodiment of the present invention is: running water is in check-valves the second interface 62 flows into the first stainless steel silk threeway 41, a part of running water in the threeway 41 of the outer silk of the first stainless steel flows to the inside and outside silk straight-through 51 of the first stainless steel, the isolating seal circle 80 that this part running water is arranged on the straight-through 51 internal thread interface inside of the inside and outside silk of the first stainless steel completely cuts off and is back in the threeway 41 of the outer silk of the first stainless steel, now running water can only flow to a PPR internal thread straight-through 31, because a PPR internal thread straight-through 31 connects with outer tube 10, running water flows in outer tube 10 from a PPR internal thread straight-through 31, meanwhile, it is straight-through 52 that boiling water flows into inside and outside the second stainless steel silk from cross heat control valve the second interface 72, and because silk inside and outside the second stainless steel straight-through 52 connects with inner tube 20, boiling water flows in the tube chamber of inner tube 20 and flows to the direction of the 2nd PPR internal thread straight-through 52.
When boiling water flow into while being arranged on outer tube 10 intraluminal this part inner tube 20, running water reverse flow in boiling water in inner tube 20 and outer tube 10, boiling water in inner tube 20 temperature in reverse convection process reduces gradually, and running water temperature in reverse convection process in outer tube 10 raises gradually.
Connect with inner tube 20 because silk inside and outside the first stainless steel leads directly to 51, the warm water after heat exchange is flowed through in the straight-through 51 inflow relief valves 90 of the inside and outside silk of the first stainless steel, and the warm water now flowing out from relief valve the second interface 92 is just capable of direct drinking.
Because the 2nd PPR internal thread straight-through 32 connects with outer tube 10, warm running water after heat exchange flows in the threeway 42 of the second stainless steels from outer tube 20 the 2nd PPR internal thread straight-through 32 of flowing through, part temperature running water in the threeway 42 of the outer silk of the second stainless steel flows to the inside and outside silk straight-through 52 of the second stainless steel, the isolating seal circle 80 that this part warm running water is arranged on the straight-through 52 internal thread interface inside of the inside and outside silk of the second stainless steel completely cuts off and passes back in the threeway 42 of the outer silk of the second stainless steel, now warm running water can only flow into water courage by the 3rd interface of a threeway 42 from the second stainless steel, reclaim thereby realize.
In embodiments of the present invention, the pipe range of outer tube 10 is 6 meters, and when the boiling water entering from cross heat control valve the second interface 72 is 100 DEG C, the warm water temperature flowing out from relief valve the second interface 92 through heat exchanging process can reach 35 DEG C; And running water is through the 3rd interface of heat exchanging process silk threeway 42 from the second stainless steel, the temperature while flowing into water courage can reach 80 DEG C, and when now the running water in water courage is heated to 100 DEG C again, the energy of consumption is less, realizes energy-conservation 80% the effect that reaches.
The embodiments of the invention that it should be pointed out that foregoing description.But; the technical staff of art technology should be appreciated that; the present invention is not restricted to the described embodiments; that in above-described embodiment, describes just illustrates principle of the present invention; the present invention also has multiple changes and improvements without departing from the scope of the invention, and these changes and improvements all fall in the claimed scope of the invention.
