Description
The present invention relates to the memory alloy control valve that a kind of temperature deformation behavior of utilizing memory alloy is carried out the method for liquid, gas flow step-less adjustment and realized this method, belong to fluid flow control field.
The Flow-rate adjustment of liquid, gas usually always realizes that by various flow valves controls traditional fluid flow regulator valve door mainly contains manually operated valve, solenoid valve and pneumatic valve, mortor operated valve.Manually operated valve can not be carried out automatic adjusting, and the precision of manual adjustment is also very poor; Solenoid valve can't carry out the continuous adjustment of flow parameter; Utilize the pneumatic valve of gaseous expansion, compressible drive and utilize motor-driven mortor operated valve complex structure, operation inconvenience, the cost height, precision is low.Above-mentioned all kinds of fluid flow regulation method and valve all are difficult to realize the adjusting of fluid flow all-range continuous stepless, therefore also are difficult to the computer High Accuracy Control of supporting enforcement fluid flow.
Task of the present invention just is to provide a kind of and utilizes the opening of temperature deformation power driving fluid runner control valve of memory alloy to close mechanism, the method for regulating with the all-range continuous stepless of realizing fluid flow; And the memory alloy control valve of realizing this method.This method and valve can carry out all-range to liquid, gas flow, high-precision continuous stepless is regulated, and helps realizing the computer control of Flow-rate adjustment, and simple in structure, easy to operate.
Fluid flow memory alloy regulating method provided by the invention is a temperature deformation behavior of utilizing memory alloy, temperature by electric heating element or fluid self-temperature regulation and control memory alloy element makes it produce corresponding crooked deformation, closes the corresponding circulation of mechanism's realization Flow-rate adjustment by the opening of crooked deformation power driving fluid runner regulating valve of memory alloy again.
The temperature deformation behavior of memory alloy is meant that along with its variation of temperature memory alloy can produce the crooked deformation with certain moment, and the size of crooked deformation and the height of temperature variation are the favorable linearity proportionate relationship, and has reducibility and reproducibility.Just because of this reducibility and reproducible " memory function " just are referred to as memory alloy.Utilize " memory function " of memory alloy,, just can make its deformation that bends, reappear corresponding degree of crook as long as be heated or be cooled to a certain setting temperature; The deformation power that produces when bending deformation is generally stronger, is enough to machinery or other controlling mechanisms of driving fluid circulation regulating valve.
The valve of realizing fluid flow memory alloy regulating method can design, manufacture all kinds according to actual needs.
The structural representation that one type fluid flow memory alloy is regulated is referring to Fig. 1, mainly by memory alloy bar 5,6, and electrothermal body 4,7, spool 9, Returnning spring 10 and valve body 2 are formed. Memory alloy bar 5,6 one ends are hinged on valve body 2 tops by articulated elements 3,8 respectively, and the other end connects spool 9 jointly; Electrothermal body 4 is fixed in respectively on the memory alloy bar 5,6; Spool 9 lower ends are the control tower shape, and the tower end embeds in the Returnning spring 10, and Returnning spring 10 is positioned in the valve core through hole 11 of valve flowing channel 1 upper wall, 1 sealing of valve core through hole 11 and runner. Electrothermal body 4,7 heating powers conduct to memory alloy bar 5,6 makes it that downward crooked deformation take place, and drives the downward straight line motion of spring force that spool 9 overcomes Returnning spring 10, enters 1 section stifled runner 11 of runner, thereby regulates flow; By the crooked deformation degree of electrothermal body 4,7 control memory alloy bars 5,6, thereby but continuous stepless is regulated and control the degree of closing that opens of 9 sections stifled runners of spool, block flow until stopping up runner 1 fully.Also can increase the quantity of memory alloy bar among the design as required, generally should be symmetrically increasing by the center,, can arrange the opposing stack of memory alloy bar as increasing deformation quantity by the garden heart of spool 9 to increase moment.
The structural representation of the fluid flow memory alloy modulating valve of another kind of type mainly is made up of electric heating element 1, memory alloy bar 2, rotating shaft 3, valve 4, valve body 5, tooth sector 6 referring to Fig. 2.Electric heating element 1 is connected one with memory alloy rod member 2 one ends, and memory alloy rod member 2 the other ends are connected in tooth sector 6, tooth sector 6 and rotating shaft 3 engagements, and rotating shaft 3 upper ends and runner valve 4 are connected as a single entity.Make electric heating element 1 heating power, conduct to the 2 crooked deformation of memory alloy rod member, drive tooth sector 6 and rotate, the rotation of tooth sector 6 makes rotating shaft 3 corresponding rotations, and the rotation of rotating shaft 3 has driven opening of runner valve again and closed.The modulating valve of this structure can be designed to runner valve 4 and can rotate from 0 ° to 90 °.
Also have a kind of structural representation of fluid temperature self-adjusting type flow control valve mainly to form by valve body 1, spool 2, memory alloy spare 3 referring to Fig. 3, the spool 2 of taper is installed in valve body 1 on the valve opening 6 between the cavity of resorption 4 and epicoele 5, its lower end is connected with memory alloy spare 3 by connecting spring 7, and memory alloy spare 3 is fixed in the cavity of resorption of the valve body 1 that fluid is introduced into.When fluid from the inlet channel of valve enter valve body 1 cavity of resorption 4 fluid temperature (F.T.)s conduct to the memory alloy spare 3 that is arranged in cavity of resorption 4, make it crooked deformation, deformation power drives spools 2 by connecting spring 7, thereby regulates the size of valve opening 6 flows.The variation of fluid temperature (F.T.) can cause the curved change of the change of memory alloy spare 3, thereby order reaches the purpose of regulated fluid flow to the degree of closing that opens of regulating valve opening 6.
Fluid flow regulation method provided by the invention and valve and traditional fluid flow regulation method and valve are compared, and can realize the adjusting of all-range highi degree of accuracy continuous stepless, and be simple in structure, easy to operate, cost is low, and the precision height can be widely used in the flow control of various liquid, gas.
