氧气瓶释放片

 

1   Introduction

The discharge indication disk is a green plastic disk. It is flush-mounted to the fuselage skin, just aft of the electronic equipment compartment external access door.

The frangible disk in the crew oxygen cylinder assembly protects the cylinder from overpressure. It blows out when pressure builds up in the overboard discharge line. This vents the bottle contents overboard through a high pressure line. The discharge indication disk covers the line outlet. The released oxygen blows the disk out of its seat.
A missing disk shows that the bottle had an over pressure discharge.
Preflight visual checks make sure the green flight crew oxygen discharge indication disk is in place.
