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
The place such as Modern Family or hotel, school, all can install hot water supply system, so that user uses hot water.But hot water in use, in water pipe, generally can retain one section of cold water.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 time 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, the for example 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, in the time that user carries out water outlet operation, this control unit can pass through the water flow temperature of this water mixing valve by sensing, if lower than setting value, this water butt can lead the cold water accumulating in pipeline, until temperature during higher than setting value, again by this water outlet member of current deflecting, in exiting water process, reach predetermined pressure once water butt water-storage pressure, can be by this pressure opening and closing valve blocking-up high-pressure cold water, change with the required cold water of low pressure cold water supply water mixing valve in this water butt, in the time that water-storage pressure declines, recover high-pressure cold water regular supply, therefore can reach the object 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 to detect water temperature, need complicated control unit to control current simultaneously.Therefore have mechanism's complexity, cost is higher, the defects 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 carry out automatic shunt to cold water part in 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, in valve body, there is valve pocket, on valve body, be provided with the water intake being communicated with valve pocket, a cold water water outlet and a hot water outlet, in valve pocket, be also provided with the spool of a piston cylinder operator, between spool and valve body, be also connected with two-way shape memory alloy, the phase transition temperature of described two-way shape memory alloy is 40-55 DEG C, described two-way shape memory alloy temperature during lower than phase transition temperature spool hot water outlet can be blocked and made to form conducting between water intake and cold water water outlet, described two-way shape memory alloy temperature deformation occurs during higher than phase transition temperature can make spool travel that cold water water outlet is blocked and make to form conducting between water intake and hot water outlet.
The present invention is arranged on the hot water supply pipe of hot water supply system and closes on water outlet, hot water supply pipe is switched to respectively on water intake and hot water outlet, 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.), in using when hot water due to pipeline, can there be the cold water under a part of normal temperature state, now cold water first passes through this diverter valve, under normal temperature state, two-way shape memory alloy is in normal state, now spool is blocked hot water outlet make to form conducting between water intake and cold water water outlet, cold water flows out from cold water water outlet.In the time that flow of hot water is crossed this diverter valve, two-way shape memory alloy temperature raises and deformation occurs, and then makes spool travel that cold water water outlet is blocked and make to form conducting between water intake and hot water outlet.Like this, hot water i.e. normal outflow, for use.Therefore the cold water before hot water flows out can not be wasted, and reaches water saving object.Ensure that the water that pipe water outlet flows out is all hot water simultaneously, avoid user to be arrived by cold water ice.
As optimization, described valve pocket comprises the spool cavity and the bypass cavity that are 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 just all arranges passage to the position of water intake, cold water water outlet and hot water outlet respectively and is communicated with bypass cavity, and described spool can slide axially and be arranged in spool cavity.After optimizing like this, structure is more reasonable and compact, is more beneficial to the admittance of current in the mobile transposition of spool and two kinds of situations, is beneficial to extension fixture working life.Meanwhile, this structure can all adopt metallic conduit to be connected to form, and is more beneficial to enforcement, makes it easily manufactured.
As further optimization, on described valve body, be positioned at axial end, spool chamber road and be also connected with valve gap, between valve gap and valve body, be provided with seal ring, 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, by opening valve gap, realize installation and the replacement of spool and memory alloy, its assembling and spool maintenance be changed all very convenient quick.Simultaneously memory alloy adopts helical spring structure ensureing at utmost to increase its deformation under the stable prerequisite of its transmission and can drive the reliability of spool travel, also can adopt the memory alloy of straight strip type structure while specifically enforcement.
In sum, the present invention can carry out automatic shunt to cold water part in hot water supply pipe and be beneficial to using water wisely, has avoided waste, also possesses simple and compact for structurely, with low cost, easy for installation simultaneously, realizes the advantages such as automation control.
