APU connection ends loaded on the hose other end and it is arranged at the cut-off that control pressure table is connected or disconnected with hose in threeway
Valve, the pressure test tap of the APU connection ends and aircraft APU match.
In order to reduce error in reading, above-mentioned air gauge is digital display type air gauge.
In order to which butt joint is protected, the vent connection blanking cover being connected to by lanyard I on vent connection is further included, it is described
The internal diameter of vent connection blanking cover matches with vent connection outer diameter.
In order to which butt joint is protected, further include the APU connection ends being connected to by lanyard II on APU connection ends and block up
Lid, internal diameter and the APU connection end outer diameters of the APU connection ends blanking cover match.
In order to play suggesting effect, warning tape is provided on above-mentioned hose.
For the ease of recording the time, label is provided on above-mentioned hose.
The beneficial effects of the utility model are：Solving when aircraft APU bleed air pressures adjust test does not have complete special tool
The problem of tool, improves work efficiency, and has saved maintenance cost.Use simple, easy to operate, easy to carry and dismounting.It deflates
The overbottom pressure of deflation valve release device after the completion of test on pipeline, prevents overbottom pressure from discharging the damage for causing equipment and people suddenly
The injury of member.The design of two deflation valves improves bleed air pressure and adjusts test equipment security.

Specific embodiment
Below in conjunction with the accompanying drawings 1, attached drawing 2 is described further the utility model.
A kind of device that test is adjusted for aircraft APU bleed air pressures, including：Threeway 5 is installed in 5 upper port of threeway
Air gauge 7, be installed on by deflation valve 4 vent connection 3 of 5 one side ports of threeway, be installed on 5 another side ports of threeway
It hose 8, the APU connection ends 11 for being installed on 8 other end of hose and is arranged at control pressure table 7 in threeway 5 and is connected with hose 8
Or the shut-off valve 6 disconnected, the pressure test tap 14 of APU connection ends 11 and aircraft APU match.In use, APU is connected
The pressure test tap 14 of end 11 and aircraft APU is attached, it is ensured that deflation valve 4 is in full off state, and shut-off valve 6 is in
Full-gear.Start APU, gas flows to 5 position of threeway by hose 8, monitors bleed air pressure by air gauge 7, ensures that APU draws
Atmospheric pressure is in normal scope.If pressure closes shut-off valve 6, prevents damage pressure close to the maximum range of air gauge 7
Table.According to the reading of air gauge 7, pressure is adjusted to normal by the pressure regulating bolt 16 of the differential pressure regulator 15 on APU
Scope.It is final slowly to open deflation valve 4, by vent connection 3 by after the gas discharge in pipeline, remove the present apparatus.
It solves the problems, such as there is no complete specific purpose tool when aircraft APU bleed air pressures adjust test, improves work efficiency, saved dimension
Protect cost.Use simple, easy to operate, easy to carry and dismounting.Deflation valve 4 on blowdown piping discharges after the completion of test
The overbottom pressure of equipment prevents overbottom pressure from discharging the damage for causing equipment and the injury of personnel suddenly.The design of two deflation valves improves
Bleed air pressure adjusts test equipment security.
Preferably, air gauge 7 is digital display type air gauge.The high-precision pressure gauge of numerical monitor is selected, instead of traditional
Mechanical pointer pressure gauge, be more suitable for using in the aircraft maintenance that pressure change is big, required precision is high.Maintenance personal
The pressure parameter of needs is easily intuitively read by digital pressure gauge, compared with mechanical pointer pressure gauge, reading misses
Subtractive is small.
