Hot gas blending is subcooled and quickly adjusts feed air temperature, reduces the influence that heater heat stagnation controls to adjust the time to temperature, cold and hot gas is mixed
Anti- deicing test heating air-flow is formed after mixed.
To achieve the above object, the technical scheme is to design a kind of high pressures of the anti-deicing air supply system of icing wind tunnel
The gas supply process of gas source feed pipeline, the high-pressure air source supply air line is as follows: the high-pressure air source drawn from high pressure air distribution system is led to
It after crossing fore filter, pneumatic ball valve, post-filter, is once depressurized by high pressure relief regulating valve, outlet imports air
The outlet of buffer, air buffer is divided into two-way after Venturi meter, digital valve, three-way control valve, passes through sky all the way
Hot-air heater, another way are bypassed as cold air, are blended by cold and hot gas and are quickly adjusted feed air temperature, reduce heater heat stagnation to temperature
Degree controls to adjust the influence of time, and anti-deicing test heating air-flow is formed after cold and hot gas blending.
Preferably, the air pressure of the high-pressure air source is 12~22MPa.
Preferably, the pneumatic ball valve is pneumatic band handwheel regulation ball valve, and loses gas power failure state valve and be automatically closed.
Preferably, the high pressure relief regulating valve is the pressure reducing valve that pneumatic stagnation pressure self-excitation aciculiform is adjusted, and is fed back to after valve always
Pressure combines feedback and flow rate feedback, and operating pressure selects the gas source of 3~6MPa, loses gas power failure state valve and quickly closes automatically
It closes, has lock pressure function.
Preferably, the venturi flow is calculated as room temperature flowmeter.
Preferably, the three-way control valve uses electrical servo, and it is true according to short-term air flow temperature regulating range to shunt size
It is fixed.
Preferably, the high-pressure air source supply air line uses gapless stainless steel tube, and wraps up insulating layer, keeps the temperature layer material
Select aluminium silicate wool.
Advantages and advantages of the present invention are to provide a kind of high-pressure air source of anti-deicing air supply system of icing wind tunnel supplies
Air pipe quickly adjusts feed air temperature by the blending of cold and hot gas, reduces the shadow that heater heat stagnation controls to adjust the time to temperature
It rings, forms anti-deicing test heating air-flow after cold and hot gas blending.
