Abstract
The utility model discloses a cold and hot water flow split valve. The cold and hot water flow split valve comprises a valve body with a valve cavity, wherein a water inlet, a cold water outlet and a hot water outlet which are communicated with the valve cavity are formed in the valve body; a valve core with a piston structure is also formed in the valve cavity; round-trip shape memory alloy is also connected between the valve core and the valve body; the phase-transition temperature of the round-trip shape memory alloy is between 40 and 55 DEG C; when the temperature of the round-trip shape memory alloy is lower than the phase-transition temperature, the valve core can block the hot water outlet, so that the water inlet is communicated with the cold water outlet; and when the temperature of the round-trip shape memory alloy is higher than the phase-transition temperature, the round-trip shape memory alloy is deformed, so that the valve core moves to block the cold water outlet, and the water inlet is communicated with the hot water outlet. According to the cold and hot water flow split valve, cold water in a hot water supply pipeline is subjected to flow splitting automatically, so that water is saved, and waste is avoided. Simultaneously, the cold and hot water flow split valve has the advantages of simple and compact structure, low cost, convenience for installation, automated control and the like.
Description
Technical field
The utility model relates to a kind of hot water supply system control valve device, the especially a kind of hot and cold water diverter 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 the waste of cold water like this.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 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 comprise 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 lower than setting value, this water butt can lead the cold water that accumulates in pipeline, until temperature during 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 be 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, recover the high-pressure cold water regular supply, therefore 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.Therefore exist mechanism complicated, cost is higher, and the defectives such as inconvenience are installed.
The model utility content
For the problems referred to above and deficiency, technical problem to be solved in the utility model 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 in the hot water supply pipe and be beneficial to the hot and cold water diverter valve that cold water reclaims.
In order to address the above problem, the utility model has adopted following technological scheme.
a kind of hot and cold water diverter valve, comprise valve body, it is characterized in that, has valve pocket in valve body, be provided with a water intake that is communicated with valve pocket on valve body, a cold water water outlet and a hot water outlet, also be provided with the spool of a piston cylinder operator in valve pocket, also be connected with the two-way shape memory alloy between spool and valve body, the phase transition temperature of described two-way shape memory alloy is 40-55 ℃, described two-way shape memory alloy temperature during lower than phase transition temperature spool hot water outlet can be blocked and made between water intake and cold water water outlet and form conducting, deformation occurs during higher than phase transition temperature described two-way shape memory alloy temperature can make spool travel that the cold water water outlet is blocked and made between water intake and hot water outlet to form conducting.
the utility model is arranged 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 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 in due to pipeline when using hot water, this moment, cold water first passed through 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 make between water intake and cold water water outlet and forms conducting, 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 made spool travel that the cold water water outlet is blocked and made between water intake and hot water outlet to form conducting.Like this, hot water i.e. normal the outflow, for use.Therefore 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 all hot water, 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 slidably 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 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 described valve body and also be connected with valve gap, be provided with seal ring between valve gap and valve body, described two-way shape memory alloy is that helical spring shape and two ends act on respectively on valve gap and spool.After optimizing like this, can realize installation and the replacement of spool and memory alloy by opening valve gap, its assembling and spool maintenance be changed all very convenient quick.Memory alloy adopts helical spring structure can increase the reliability that its deformation can drive spool travel simultaneously.
In sum, the utility model can partly carry out automatic shunt to cold water in the hot water supply pipe and be beneficial to using water wisely, has avoided waste, also possesses simultaneously simple and compact for structurely, with low cost, easy for installation, realizes the advantages such as automation control.
