Tested in the product of pressurised zone, test whether they can bear customary pressurizing action due to airborne vehicle pressure charging system
And the air pressure in the spacecraft module brought.
In order to which technical scheme is more clearly understood, below just the present invention pressure-resistant performance test system master
Test operation process is wanted to illustrate.
First, testing crew carries out leak detection test to main box 1, it is ensured that main box 1 is the casing of sealing；
Then, the product opened on main box 1 is put into door, is then placed in the product for needing to carry out pressure-resistant performance test, and
Close product and be put into door, it is ensured that sealing；
Then, source of the gas 2 is passed sequentially through into pressure regulator valve 3, manual switch valve 4 and hollow pipeline with main box 1 to be connected, connect
Aerobic source 2；
Then, intake valve 6 and air bleeding valve 7 are closed, the output valve on source of the gas 7 is opened, regulation pressure regulator valve 3 is to default
Pressure；
Then, testing crew slowly opens intake valve 6, and the gas that recording manometer 5 is detected in the pipeline obtained is situated between
Matter pressure data (is considered as the gas medium pressure data being equal in main box 1)；
Then, when pressure gauge detects the gas medium pressure of acquisition to reaching default pressure value (according to testing crew
Needs come it is clear and definite) after, testing crew closes intake valve 6 and simultaneously starts timer, while corresponding at the time of record different in real time
Pressure value；
Then, the gas medium pressure of experiment is wanted (specifically when the gas medium pressure in main box 1 reaches testing crew
Can be equal to the spacecraft internal air pressure after supercharging), and after continue for the desired duration of testing crew, stop examination
Test, at this time, intake valve 6 can be closed, then open air bleeding valve 7 so that the gas medium in main box 1 discharges, main
Pressure recovers normal pressure in casing 1；
Finally, the product opened on main box 1 is put into door, takes out product, then carries out performance and outward appearance to the product
Check.
If (such as occur it should be noted that the product has not possessed defined standard performance parameter after being powered serious
Noise, can not either be powered operation situations such as) or outward appearance be damaged, then illustrate that the product does not meet testing crew
It is required that pressure-resistant performance., whereas if the product still possesses defined standard performance parameter, and outward appearance is not impaired, says
The pressure-resistant performance of the bright product Pass Test personnel requirement.
It should also be noted that, during test operation, in order to prevent the hypertonia of gas medium, cause into
The product for performance that row is pressure-resistant and the pressure-resistant performance test system damage of the present invention, therefore, are especially provided with safety valve, pass through the peace
Full valve, can be reached in the internal pressure of main box 1 as defined in after upper pressure limit value, being capable of timely pressure release；For testing crew,
, it is necessary to which the moment pays close attention to the reading of pressure gauge 5 during being pressurizeed to main box 1, and manual switch valve 4 is coordinated to enter to advance
Row regulation, prevents that pressure is excessive.
In addition, during test operation, the product closed on main box 1 is put into front of the door, it is necessary to sealing ring be cleared up dry
Only, gas leakage is prevented.After off-test, main box is cleared up in time, keeps the cleaning of main box.
In summary, compared with prior art, on a kind of spacecraft provided by the invention product pressure-resistant performance test
System, it can simulate the spacecraft internal air pressure after providing a supercharging, be so as to detect product on spacecraft
The no spacecraft internal air pressure that can be born after supercharging, accurately to grasp the pressure-resistant performance of product on spacecraft, favorably
In popularizing, it is of great practical significance.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
