Equipped with pressure tap 13, for the gas pressure on pressure measuring device test gas exhaust piping 7 (before equivalent nozzle 12).
The present invention also provides a kind of control methods based on above-mentioned air turbine starter air supply system, specially：It starts
When machine 10 starts, the first solenoid valve 2, pressure regulator valve 5 and third solenoid valve 11 are first opened, gas enters exhaust pipe by air inlet pipeline 1
Road 7 goes out from equivalent nozzle row 12, by adjusting the aperture of pressure regulator valve 5, controls the capacity of equivalent nozzle 12, equivalent nozzle 12
Lasting exhaust closes third solenoid valve 11 until after the pressure of equivalent nozzle 12 reaches specified value and stablizes, and opens the second electricity
Magnet valve 8, the closure of normally open solenoid valve 9, supply air line 6 are connected to the gas supply of starter 10, the start-up operation of starter 10 at this time.
It completes after starting, closes the steam supply valve of starter 10, and open third solenoid valve 11, equivalent nozzle 12 is kept to be vented
A period of time turns off, it is preferred that and the time that equivalent nozzle 12 is vented is more than lag time when second solenoid valve 8 is closed,
In the present embodiment, continues that equivalent nozzle 12 is kept to deflate 20~30 seconds after 10 proceed-to-send of starter, pass through equivalent nozzle 12
It deflates, it can be by the decrease in air pressure after pressure regulator valve 5 to 2kgf/cm2, before the steam supply valve closing of starter 10, supply air line 6
Pressure can be reduced to, about 2kgf/cm identical as pressure after pressure regulator valve 52, meet the requirement of technological standards.While second
Solenoid valve 8 is lagged several seconds after the opening of third solenoid valve 11 and is closed, and normally open solenoid valve 9 disconnects at this time, the gas of supply air line 6 by
Normally open solenoid valve 9 is discharged so that the inlet pressure of starter 10 is reduced to zero, and height will not be caused in starter 10 next time of starting

Such as Fig. 2, for the supply gas pressure curve graph that four pressure taps 13 in Fig. 1 measure respectively, wherein I is system pressure, II
For pressure regulation downstream pressure, III is pressure before equivalent nozzle, and IV is starter inlet pressure, from figure 2 it can be seen that system into
Atmospheric pressure remains 5kgf/cm2Left and right, the substantially 2kgf/cm after 5 pressure regulation of pressure regulator valve2Left and right, passed through exhaust before this
Pipeline 7 is deflated, then it is 2kgf/cm that the pressure before equivalent nozzle 12 is increased by zero2Or so, after pressure stability, close third electricity
After magnet valve 11, the pressure before equivalent nozzle 12 is reduced to 0, and after the opening of second solenoid valve 8,10 inlet pressure of starter is gradually by 0
It is increased to 2kgf/cm2, keep the gas of steady pressure to supply, after proceed-to-send, be then turned on third solenoid valve 11, and close
Second solenoid valve 8, due to second solenoid valve 8 lag several seconds close, while at normally open solenoid valve 9 deflate so that starter 10 into
Mouth pressure is gradually reduced to 0, and when starting next time, entrance no pressure impacts.After third solenoid valve 11 opens a period of time (30s)
It closes, pressure is also gradually reduced to 0 before equivalent nozzle 12.It can be seen that by above-mentioned supply gas pressure curve, air supply system of the invention
It disclosure satisfy that the technological requirement that starter 10 starts, and impacting with high pressure starter 10 will not be caused, improve making for starter 10
Use the service life.
