Abstract
The utility model relates to a constant water temperature controlling valve, comprising the piston with axially extending bore, the valve seat in the axial end of the piston, a valve body on the other axial end of the piston, a valve open exists between the valve body and the valve base. The valve body moves axially or away from the valve seat in order to change the valve open and regulate the liquid flow in the inner flowing passage. The valve body consists of a locking polarizing spring, and the valve base consists of a form memorizing alloy spring, and the piston moves under the mutual balance gained by the form memorizing alloy spring tension and the locking polarizing spring. The valve excels in dexterity, quick in response, and long in the lifespan.
Description
Technical field
The utility model relates to a kind of water temperature control valve, especially a kind of mixing faucet and water heater gondola water faucet of being applicable to, speed of response than original technology more rapidly, and working life very long control valve.
Background technique
What the tradition temperature conditioning unit adopted is the rheid of copper.It is a kind of half fluidity substance that expands or shrink that will produce when temperature changes.In the practice, the inventor finds that there is following shortcoming in above-mentioned water temperature control valve: one, owing to be half fluidity substance, its speed of response is just slow naturally.We once had such experience when using hot water in the kitchen, though we are set at certain value with temperature exactly, but still a period of time, height was for the moment low for the temperature of water, and this is the variation owing to hydraulic pressure, the mistake heating phenomena that the speed of response of the temperature sense body of water valve the inside causes too slowly.Two, working life short, the life-span of the control valve that the rheid of this copper is made only one year about.
In order to overcome above-mentioned shortcoming, the inventor has developed marmem (SMA, responsive memory alloy), being used on the new water temperature control valve, and has adopted the piston spring structure.Side at piston is installed shape memory alloy spring, at the opposite side of piston common spring is installed, and makes the spring on both sides form a kind of state of equilibrium.Wherein, it is certain that the pressure that the spring of common spring one side is subjected to is installed, if temperature fluctuates, corresponding variation will take place the power on the SMA spring, thereby plays the effect of regulating water mixing proportion, control temperature.That is to say, if the overheated spring force that turns down hot-water valve that just produces of mixing water.As long as in advance temperature is configured, spring will be regulated hot-water valve automatically to guarantee temperature constant.The basic ideas of this design are the same with half fluidity substance that adopts copper, but because the speed of response of marmem is faster, so big fluctuation can not take place in the temperature of water outlet.Simultaneously, this SMA memory spring can reach more than 5 years working life.
Summary of the invention
The purpose of this utility model provides a kind of agility height, the constant control valve of maintenance water outlet water temperature that reaction velocity is fast.The technological scheme that the utility model adopted is:
A kind of thermostatted water temperature control valve comprises: a piston, have axial drilling, and be formed with the internal flow path of using to the fluid of outlet from entrance extension in the axial drilling; One valve base is arranged at an axial end of this piston; One valve body, be arranged at another axial end of this piston, this valve body and this valve base cooperation and in this internal flow path in defining a valve opening between the two, this valve base can axially be shifted to or move apart to this valve body changing this valve opening, in order to the flow through fluid flow of this internal flow path of adjustment; It is characterized in that: described valve body comprises a locked type polarization spring, in order to drive this valve body, to change this valve opening in a direction; Described valve base comprises a shape memory alloy spring, is used for applying this locked type polarization spring of opposing power of moving this valve body with the response thermal distortion and changes the valve opening; One end of described memory alloy spring is provided with screw-casing, and an end of screw-casing is enclosed within on the piston; Memory alloy spring is installed in the described valve base, produces different tension force and the mutual balanced action between locked type polarization spring comes mobile piston by this memory alloy spring.
Described thermostatted water temperature control valve also comprises and is used for regulating regulation cock and the scale location piece of this valve body of temperature controlling along the axis rotation.
Described thermostatted water temperature control valve also comprises this valve body is driven nut with respect to the advance and retreat that moving axially of this valve base is limited in the prespecified range.
Described thermostatted water temperature control valve is provided with pad, when pad moves near this valve base at described valve body, is used for replenishing the elastic force of SMA memory alloy spring.
Working principle of the present utility model is: at first, with regulation cock required different water-exit temperature is set according to the scale location piece, when cold water and hot water two water intakes that are positioned at the piston two ends by valve body enter valve respectively, during through screw-casing, hot and cold water mixes, then by SMA shape memory alloy spring cavity, under different mixed water temperature inductions, this SMA memory alloy spring produces different tension force and the mutual balanced action of locked type polarization spring comes mobile piston, the mobile flowrate proportioning of then controlling hot and cold water accurately of piston reaches the purpose of controlling mixing water constant temperature.
The beneficial effects of the utility model are: after the utility model is applied to mixing faucet and water heater, can regulate the flowrate proportioning of hot and cold water faster, more stable, more accurately automatically.Reach set temperature, keep the constant temperature of water outlet, and prolong greatly working life.
