The electronic dynamic adjustments air-valve 103 that can regulate a wind intake in the present embodiment is control valves of a mechanical self-operated type air pressure automatic balance function, be installed in wind air inlet 102 one time, comprise Electric air valve valve body 5, it is characterized in that valve inner has following symmetrical structure: both sides respectively have a lightweight valve plate 12 to be installed on the Electric air valve valve body 5 by hinge 9 is installed; Respectively there are at least two fine setting flexural springs 10 to be installed on the Electric air valve valve body 5, and on the another side that is pressed in lightweight valve plate 12 after the initial deformation.Electric air valve valve body 5 middle parts are provided with the water conservancy diversion pin 11 in restriction lightweight valve plate 6 final positions, and position is equipped with position spring 13 and plays screw 3 with plug in the middle of it; The top, windward side of two lightweight valve plates 12 of symmetry and the two ends of a flexural spring sheet 4 with symmetrical structure are fixedly linked, the center of flexural spring sheet 4 is opened a circular hole and is hinged on plug and beats on the screw 3, this plug is played the other end contact of screw 3 on the outer of cam 2, and cam 2 is provided with one can drive the rotating shaft 1 that cam 2 rotates.When cam 2 little strokes slowly rotate, force the adjustment plug to beat the position of screw 3 by position spring 13, thereby make flexural spring sheet 4 and fine setting spring 10 produce different active position and opplied moment with high elastic coefficient.
The outer surface of described casing 100 is provided with flow indication and coils 6 and be installed in the rotating shaft 1 quarter, and the scale of this indication dish at quarter, the angle stroke of rotating shaft and the equivalent coefficient of elasticity that acts on spring (contain flexural spring sheet 4, finely tune spring 10) become mathematics corresponding relation one by one.
The angle stroke YE 7 that is installed in casing 100 outsides accept intelligent temperature controller output the standard control signal (as 0～10VDC) the angle stroke that produces 0～90 degree, thus the secondary return air amount that the adjusting of a corresponding wind air quantity 0%～100% and ratio are regulated.
Present embodiment also disposes the integrated indoor mount type intelligent temperature controller of a band temperature sensor, and it is the general purpose controller product of a standard, and its output signal is connected to YE 7 and three-speed motor 107 respectively by cable.
The technological principle that its technical problem that solves the utility model adopts is:
Intelligent temperature controller outputting standard control signal (is given angle stroke YE 7 as 0～10VDC), YE 7 is driven into certain fixed angle with rotating shaft 1, electronic center line valve plate forwards this angle synchronously to, cam 2 is also fixed at corresponding angle, play screw 3 by the plug of tight contact on cam 2 outers and utilize position spring 13 pullings or promote flexural spring sheet 4 to corresponding position, flexural spring sheet 4 forms positive moment M to lightweight valve plate 12 jointly with the fine setting flexural spring 10 common equivalent springs that form
1When the airflow passes air-valve, lightweight valve plate 12 both sides produce pressure drop Δ P, and pressure drop Δ P makes air-flow give lightweight valve plate 12 rightabout countertorque M to 12 one of the generation of lightweight valve plate and flexural spring sheet 4, fine setting flexural spring 10
2When air-flow acted on enhancing to lightweight valve plate 12, pressure drop Δ P also increased thereupon, M
2Also increase.Work as M
2Greater than M
1The time, lightweight valve plate 6 is to the closing direction action, and flexural spring sheet 4 also increases to M for lightweight valve plate 6 countertorque with the equivalent spring that fine setting flexural spring 10 forms
3, reach the balance of moment at last, make valve plate rest on a new position, this moment M
2=M

Δ P is just about the function of θ like this:
ΔP＝ΔP(θ)
Dimensionless resistance coefficient ζ also can be expressed as the function of θ: ζ=ζ (θ)
Flow area A also can be expressed as the function of θ: A=A (θ)
Suppose atmospheric density ρ, by can the flow through air quantity Q of Electric air valve of fluid mechanics equation:
The utility model is exactly to utilize the nonlinear interaction of this equivalent flexural spring to set up rational mathematical simulation relation, make wind intake Q become at last irrelevant with θ, with the irrelevant constant of air incoming-flow pressure P, only the corner with cam 2 has relation, and flowing through the wind intake Q of Electric air valve and the angle stroke (aperture) of YE is unique corresponding relation of mathematics one by one, and the flow of the electronic dynamic adjustments air-valve of this pressure independent type is adjustable in 0%～100% scope.
When the aperture of angle stroke actuator is zero, flexural spring sheet 4 is to react on lightweight valve plate 12, overcome fine setting flexural spring 10 and given lightweight valve plate 12 positive interaction moments, only need this moment very little incoming-flow pressure just electronic dynamic adjustments air-valve can cut out, and incoming-flow pressure is big more, the power of closing of lightweight valve plate 12 is just big more, thereby closes the intake of a wind.
Utilize the variable air rate of a wind of aperture realization of intelligent temperature controller output analog signals control YE.In case power failure or intelligent temperature controller output shutdown signal, the spring reset function of dependence actuator are closed the air inlet 102 of a wind automatically and are closed the electronic center line valve plate 108 of secondary return air.Because wind and secondary return air adopt same YE, regulating the back through ratio mixes, transfer out different wind pushing temperatures and different mixing wind air outputs by blower fan power, realize the variable air rate effect of wind variable air rate, secondary return air variable air rate, end equipment air-supply.And indoor temperature is the aperture by the high-grade intelligent algorithm simulation amount control YE of intelligent temperature controller, and the automatic loop control three fast blower fans of switching value finally reach indoor variable air rate control and thermal comfort control simultaneously.
At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.
For example: a wind air inlet 102 described in the utility model and secondary return air air inlet 101 can be installed on any one panel of the cabinet panel that removes terminal air outlet 105 places.
For example: a wind variable air rate device described in the utility model can adopt electronic dynamic adjustments air-valve 103 combinations of a plurality of modularizations and evenly install, a shared YE 7, to shorten flow direction dimension, improve the disposal ability and the control accuracy of a wind intake.
For example: the inside of casing 100 described in the utility model can increase a bringing-up section (post bake section) again, and after this bringing-up section can be installed in fan outlet, bringing-up section can adopt electrical heating or hot water mode of heating again.
For example: blower fan 106 described in the utility model can adopt two silent ventilators to be installed in parallel, and a shared three-speed motor or dispose two independently three-speed motors is to improve air output.
For example: increase the air port of the diffusing head piece of stripe shape or other type on the terminal air outlet 105 of casing 100 described in the utility model, to improve air current composition.
For example: secondary return air air inlet 101 described in the utility model, electronic center line valve plate 108, leaf filter 104, can delete, only keep casing 100, a wind air inlet 102, electronic dynamic adjustments air-valve 103, terminal air outlet 105, blower fan 106, three fast tap motors 107.Be deformed into a kind of compacter pressure independent type air quantity variable end device that can electronic dynamic adjustments.
