Abstract
The utility model relates to an automatic adjusting valve, comprising a valve body, blades and a rotary shaft. The utility model is characterized in that the upper end of the rotary shaft and the part out of the valve body are wrapped with torsion springs which are provided with dust covers. Spiral coils and memory alloy elements are arranged between the blades and a support frame arranged on the valve body; the memory alloy elements have the function of sensing the temperature and opening and closing the blades. The adjusting valve has simple structure and sensitive and accurate temperature sense.
Description
The utility model relates to valve field.
Though used valve generally can not be regulated automatically or can regulate automatically but must can not satisfy usage requirement by artificially adjusting and sensitivity inadequately in air-conditioning, ventilation duct lead to.
The purpose of this utility model is: a kind of automatic regulating valve is provided, and this valve can vary with temperature and valve is is accurately opened and closed, and is quick on the draw.
The purpose of this utility model reaches like this: be provided with bag torsion spring thereon on the part outside rotating shaft upper end, valve body, on this torsion spring, be provided with cover dust-proof cover thereon, at blade be located between the support on the valve body and be provided with helical cast memory alloy element, play temperature-sensitive and carry out the blade switching function by this memory alloy element, thereby the purpose of this utility model has just reached fully.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing 1 is this automatic regulating valve schematic representation.Wherein, 1 represent valve body; 2 represent torsion spring; 3 represent dust-proof cover; 4 represent rotating shaft; 5 represent support; 6 represent memory alloy element; 7 represent blade.
Accompanying drawing 1 is the opening state of valve blade.From accompanying drawing 1 as seen, be provided with the rotating shaft 4 that runs through wherein at valve body 1 center, blade 7 one sides are fixed in the rotating shaft 4, can rotate with rotating shaft 4.The utility model feature is: be provided with bag torsion spring 2 thereon on the part outside rotating shaft 4 upper ends, valve body 1, be provided with dust-proof cover 3 on torsion spring 2, at blade 7 be located between the support 5 on the valve body and be provided with helical cast memory alloy element 6.Wherein, it also can be other shapes that valve body is square, by cold rolled sheet through the bending, be welded.Rotating shaft 4 has blade 7 one sides to be fixed thereon, and can play the folding effect.Blade 7 is made by cold rolled sheet.Torsion spring 2 is made by high strength, high elasticity steel, when memory alloy element is soft condition at normal temperatures, because the torsion spring effect can make blade 7 relative valve bodies 1 be " unlatching " state.When reaching memory temperature, memory alloy element shrinks, and the torsion of this torsion spring 2 is overcome, and makes valve be closed condition.On torsion spring 2, be provided with anti-main cover 3, with protection dust etc. to torsion spring 2, the infringement of rotating shaft, bearing (not drawing among the figure), the dust-proof cover 3 in the accompanying drawing 1 is the states that are not buckled on the torsion spring 2, so that can see the position of torsion spring 2 clearly.When this cover is buckled on the torsion spring has been exactly the user mode of valve.
The utility model is played memory temperature and is carried out the valve opening dual role by memory alloy element, and for this reason, this memory alloy element is made to the helical cast, and one terminates at the support of being located on the valve body 15, and the other end is connected on the rotating shaft offside on the blade 7.When at normal temperature, memory alloy element is in soft condition, thereby blade 7 is opening state to valve body 1 relatively, when reaching the memory temperature of this element, memory alloy shrinks, thereby whole memory alloy element also shrinks, overcome the torsion of torsion spring 2, thereby make valve be closed condition.When temperature in the valve is lower than rated temperature and during near normal temperature, memory alloy is soft condition again, under the effect of torsion spring (2), memory alloy element 6 loosens, and valve is decontroled and opened.
The utility model automatic regulating valve is simple in structure, the temperature sensation sensitivity, accurately, not fragile, cost is low, can be used as air conditioner, fire damper in vent duct and uses, also can be used as other product of regulating room temperature automatically and use.
