Description

Based on the intelligent water-saving switch of memory alloy
Technical field
The utility model relates to a kind of intelligent water-saving switch based on memory alloy.
Background technique
Water is the valuable source that the mankind depend on for existence, and all productive lifes all be unable to do without water, it is reported, China's gross amount of water resources is 2.8 tcms, occupies the 6th, the world.But calculate per capita, water resources ownership per capita about 2300 cubic metres, is equivalent to 1/4th of world's water resource of per capita, and occupy the 121st, the world, therefore, China's water resource of per capita is not enriched, the phenomenon of long-term existence lack of water.Add, water resource optimal allocation is not in place, develops unreasonable allocation, and waste is serious, and utilization ratio is low and spatial and temporal distributions uneven, ignores the problems such as reuse of wastewater and also exacerbates lack of water phenomenon.
At present, school and integrated mill, carry out the control measures of central heat supply water for student and employee.But because conveying hot water pipeline is longer, when therefore just having brought into use hot water, first the cold water remained in hot-water line can be discharged; And user uses the time disunity again of hot water, the hot water remained in hot-water line causes water temperature drop because of stop, the requirement of people has not been reached to water temperature during follow-up re-using, by opening hot-water switch, these water can only be discharged in sewage pipe completely, could use hot water, this wastes water resources greatly.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provide a kind of can the intelligent water-saving switch based on memory alloy of saving water resource.
The technical solution adopted in the utility model is: a kind of intelligent water-saving switch based on memory alloy, comprises the first valve and the second valve; The first described valve comprises valve body, memory alloy spring and sleeve; Described valve body is provided with water intake, backwater mouth and water outlet; Described sleeve and memory alloy spring are arranged in valve body, and described sleeve is the tubular of one end open, and the sidewall of sleeve is provided with backwater mouth and water outlet, and one end of memory alloy spring is connected with valve body, and the other end is connected with the opening end of sleeve; The backwater mouth of described valve body is communicated with the backwater mouth on sleeve;
The second described valve comprises the second valve body, the second memory alloy spring, bias spring and the second sleeve, and the second described valve body is provided with two water intakes and a water outlet; The second described memory alloy spring, bias spring and the second sleeve are arranged in the second valve body, and the two ends of the second sleeve are connected with the two ends of the second valve body respectively by the second memory alloy spring and bias spring; The second described sleeve in a tubular form; The sidewall of the second sleeve is provided with two water intakes; Two water intakes on second valve body are communicated with two water intakes in the second sleeve lateral wall respectively;
The water outlet of the first valve body is communicated with the water intake on the second valve body of the second valve by connecting tube.
Above-mentioned based in the intelligent water-saving switch of memory alloy, the backwater mouth on the first described valve body and water outlet coaxial, phase difference is 180 °, and sidewall mouth of a river last time of sleeve and the phase difference of water outlet are 180 °.
Above-mentioned based in the intelligent water-saving switch of memory alloy, the one end near the second memory alloy spring on the second described valve body is provided with temperature adjustment screw, and temperature adjustment screw is connected with the second memory alloy spring.
Above-mentioned based in the intelligent water-saving switch of memory alloy, described to recall the material that alloy spring and the second memory alloy spring adopt be Ultimum Ti.
Above-mentioned based in the intelligent water-saving switch of memory alloy, the material that described sleeve and the second sleeve adopt is carbon fiber in epoxy.
Compared with prior art, the beneficial effects of the utility model are:
When the utility model uses, running water pipe connects the backwater mouth on valve body of the present utility model and the water intake on the second valve body; Hot-water line connects the water intake on valve body; When using hot water, open the switch on hot-water line, just started owing to flowing through the temperature of water in memory spring lower, memory alloy spring is undeformed, because the water in hot-water line is higher than the pressure of running water pipe, cold water is less than 0.91 with the ratio of the caliber of hot water.Therefore, after opening hot-water switch, water flows in running water pipe by sleeve and is reclaimed; When water temperature reaches the phase transformation critical temperature of memory alloy spring, memory alloy spring undergoes phase transition rapidly, to the right drive spool, is sealed by backwater mouth, and sleeve under shed aims at the water outlet flowing to the second valve gradually, thus hot water is injected the second valve; The utility model achieves the recovery of the cold water remained in hot-water line, avoids the waste of water resources, has saved water resources.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Structural representation when Fig. 2 is the utility model use.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises the first valve and the second valve; The first described valve comprises valve body 1, memory alloy spring 3 and sleeve 2; Described valve body 1 is provided with water intake 11, backwater mouth 12 and water outlet 13, and coaxially, phase difference is 180 ° for backwater mouth 12 and water outlet 13; Described sleeve 2 and memory alloy spring 3 are arranged in valve body 1, the described tubular of sleeve 2 in one end open, and the sidewall of sleeve 2 is provided with backwater mouth 21 and water outlet 22, and the phase difference of backwater mouth 21 and water outlet 22 is 180 °, and disalignment.One end of memory alloy spring 3 is connected with valve body 1, and the other end is connected with the opening end of sleeve 2.The water intake 11 of memory alloy spring 3 on valve body 1 is arranged, and the backwater mouth 21 on described sleeve 2 is communicated with a backwater mouth 12 of valve body 1.
The second described valve comprises the second valve body 5, second memory alloy spring 7, temperature adjustment screw 8, bias spring 9 and the second sleeve 6, and the second described valve body 5 is provided with two water intake 51,52 and water outlets 53; Described temperature adjustment screw 8 is arranged on one end of the second valve body 5, and the second described memory alloy spring 7, bias spring 9 and the second sleeve 6 are arranged in the second valve body 5, and one end of the second sleeve 6 is connected with temperature adjustment screw by the second memory alloy spring 7; The described water intake 51 of the second memory alloy spring 7 on the second valve body 5 is arranged.The other end of the second sleeve 6 is connected with the second valve body 5 by bias spring 9.The second described sleeve 6 in a tubular form; The sidewall of the second sleeve 6 is provided with two water intakes 61,62; Two water intakes 51,52 on second valve body 5 are communicated with two water intakes 61,62 on the second sleeve 6 sidewall respectively.The water outlet 13 of the valve body 1 of the first valve is communicated with the water intake 61 on the second valve body 5 of the second valve by connecting tube 4.The described material recalling alloy spring 3 and the employing of the second memory alloy spring 7 is Ultimum Ti (material also can be other memory alloys); The material that described sleeve 2 and the second sleeve 6 adopt is carbon fiber in epoxy.
