Description
Technical Field
The utility model relates to a measuring tool of adjustable gassing valve opening angle.
Background
The large-bypass-ratio commercial aircraft engine is generally provided with an adjustable bleed valve for changing the relation between inner bypass airflow and outer bypass airflow under different working states, so that the performance of the high-pressure rotor and the low-pressure rotor is more matched. Fig. 1 shows a schematic diagram of a common adjustable bleed valve structure of an aircraft engine, wherein the adjustable bleed valve 9 comprises a valve 90, a mounting seat 91, a valve rotating shaft 92 and a valve connecting part 93. The valve connecting portion 93 is in transmission connection with a valve driving shaft (not shown in the figure), so that the valve driving shaft is used as power input to drive the valve 90 to rotate by taking the valve rotating shaft 92 as a rotating axis, and the size of the opening angle of the adjustable deflation valve is adjusted. The shutter opening angle refers to the opening angle of the shutter 90.
The air bleeding amount required by the aircraft engine under different working conditions is inconsistent, and the air bleeding amount is controlled by the opening angle of the air bleeding valve. This requires precise measurement of the angle of the bleed valve during assembly of the aircraft engine and establishment of a relationship between the angle and the hydraulic ram linear displacement sensor to provide precise control of bleed air volume during operation of the aircraft engine.
The measurement methods adopted in the current industry mainly comprise:
1. converting the angle into displacement for measurement: and measuring the displacement of the valve in the opening process through a threaded mandril penetrating into the flow channel, and converting through a trigonometric function. The main drawback of such methods is the measurement error introduced by the thread pin clearance; meanwhile, since the flow channel surface is not a straight line, a large error is caused by the approximate calculation using the trigonometric function.
2. The parallelogram rotates the angle out for measurement: the angle is transferred to the outside of the engine for measurement through a parallelogram positioning structure arranged at the rotating shaft of the valve. The main disadvantages of such methods are that the measuring mechanism is complex, and the installation gap is liable to cause measuring errors; meanwhile, the structure is a cantilever, and a measuring system is easy to vibrate after installation to cause measuring errors.
Therefore, a measuring tool for the opening angle of the adjustable deflation valve is needed to realize the rapid and accurate measurement of the opening angle of the adjustable deflation valve.
