Abstract
The invention discloses an automatic cold water and hot water diverting valve, which comprises a valve body provided with a valve cavity, wherein the valve body is provided with a water inlet, a cold water outlet and a hot water outlet that are communicated with the valve cavity; a piston type valve core is further arranged in the valve cavity; two-way shape memory alloy is further connected between the valve core and the valve body; a phase transition temperature of the two-way shape memory alloy is 40-55 DEG C; when the temperature of the two-way shape memory alloy is less than the phase transition temperature, the valve core can block the hot water outlet and communicate the water inlet with the cold water outlet; and when the temperature of the two-way shape memory alloy is greater than the phase transition temperature, the deformation occurs so that the valve core can displace to block the cold water outlet and communicate the water inlet with the hot water outlet. The automatic cold water and hot water diverting valve can automatically divert a cold water part in a hot water supply pipe so as to save water and avoid waste; and further the automatic cold water and hot water diverting valve is simple and compact in structure, low in cost and convenient to install, and achieves the automatic control.
Description
Technical field
The present invention relates to a kind of hot water supply system control valve device, the especially a kind of cold water hot water automatic shunt valve that can shunt cold water hot water.
Background technique
Hot water supply system all can be installed in the place such as Modern Family or hotel, school, so that the user uses hot water.But hot water in use, generally can retain one section cold water in water pipe.After cold water need to being bled off, hot water just can flow out.Will cause like this waste of cold water.Particularly use water heater that hot water is provided and water heater distance when far away with water spot, it is outstanding especially that this problem seems.
In the prior art, the technology that has existed part to address the above problem, for example the water outlet device of China's number of patent application 200820214233.1 disclosed a kind of reclaiming cold water functions mainly comprises a water mixing valve, at least one water outlet member, a water butt, a control unit and a pressure opening and closing valve in this device; When the user carries out the water outlet operation, but this control unit sensing is by the water flow temperature of this water mixing valve, if be lower than setting value, this water butt can lead the cold water that accumulates in the pipeline, when treating that temperature is higher than setting value, again with this water outlet member of current deflecting, in exiting water process, when in case the water butt water-storage pressure reaches predetermined pressure, can by this pressure opening and closing valve blocking-up high-pressure cold water, change with the required cold water of the supply water mixing valve of the low pressure cold water in this water butt, when water-storage pressure descends, then recover the high-pressure cold water regular supply, so can reach the purpose of cold water circulation recycling and environmental protection and energy saving.
Although said apparatus can be recycled cold water, need to adopt temperature testing organization that water temperature is detected, need simultaneously complicated control unit that current are controlled.So exist mechanism complicated, cost is higher, and the defectives such as inconvenience are installed.
Summary of the invention
For the problems referred to above and deficiency, technical problem to be solved by this invention is: how to provide a kind of simple in structure, with low cost, easy for installation, can partly carry out automatic shunt to cold water among the hot water supply pipe and be beneficial to the cold water hot water automatic shunt valve that cold water reclaims.
In order to address the above problem, the present invention has adopted following technological scheme.
A kind of cold water hot water automatic shunt valve, comprise valve body, it is characterized in that, has valve pocket in the valve body, be provided with a water intake that is communicated with valve pocket on the valve body, a cold water water outlet and a hot water outlet, also be provided with the spool of a piston cylinder operator in the valve pocket, also be connected with the two-way shape memory alloy between spool and the valve body, the phase transition temperature of described two-way shape memory alloy is 40-55 ℃, spool can be blocked hot water outlet and so that form conducting between water intake and the cold water water outlet when described two-way shape memory alloy temperature was lower than phase transition temperature, deformation occurs when described two-way shape memory alloy temperature is higher than phase transition temperature spool travel is blocked the cold water water outlet and so that form conducting between water intake and the hot water outlet.
The present invention is installed on the hot water supply pipe of hot water supply system and closes on water outlet, the hot water supply pipe is switched to respectively on water intake and the hot water outlet, the cold water water outlet connects separately a water storage box or is connected to other places that need to use cold water (as flush the toilet or water flowers etc.), can there be the cold water under a part of normal temperature state when using hot water because in the pipeline, this moment, cold water passed through first this diverter valve, under the normal temperature state, the two-way shape memory alloy is in normal state, this moment, spool was blocked hot water outlet and so that form conducting between water intake and the cold water water outlet, cold water flows out from the cold water water outlet.When flow of hot water was crossed this diverter valve, the two-way shape memory alloy temperature raise and deformation occurs, and then spool travel is blocked also the cold water water outlet so that form conducting between water intake and the hot water outlet.Like this, hot water i.e. normal the outflow, for use.So the cold water before hot water flows out can not wasted, and reaches water-saving.Guarantee that simultaneously the water that pipe water outlet flows out is hot water all, avoid the user to be iced by cold water and arrive.
As optimization, described valve pocket comprises a spool cavity and bypass cavity that is set up in parallel, one side of described spool cavity is communicated with water intake, cold water water outlet and hot water outlet respectively, the opposite side of spool cavity all arranges passage over against the position of water intake, cold water water outlet and hot water outlet respectively and is communicated with the bypass cavity, and described spool can be slidingly arranged in the spool cavity vertically.After optimizing like this, structure is more reasonable and compact, more is beneficial to the admittance of current in the mobile transposition of spool and the two kinds of situations, is beneficial to extension fixture working life.Simultaneously, this structure can all adopt metallic conduit to be connected to form, and more is beneficial to enforcement, makes it easily manufactured.
As further optimization, be positioned at axial end, spool chamber road on the described valve body and also be connected with valve gap, be provided with seal ring between valve gap and the valve body, described two-way shape memory alloy is that helical spring shape and two ends act on respectively on valve gap and the spool.After optimizing like this, can realize installation and the replacement of spool and memory alloy by opening valve gap, it is all very convenient quick that its assembling and spool maintenance are changed.Memory alloy adopts helical spring structure guaranteeing at utmost to increase the reliability that its deformation can drive spool travel under the stable prerequisite of its transmission, also can adopt the memory alloy of straight strip type structure during implementation simultaneously.
In sum, the present invention can partly carry out automatic shunt to cold water among the hot water supply pipe and be beneficial to using water wisely, has avoided waste, also possesses simultaneously the advantages such as simple and compact for structure, with low cost, easy for installation, realization automation control.
