Embodiment Construction
[0030] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.
[0031] Such as Figure 1 to Figure 6 As shown, a kind of aircraft safety oxygen release device provided by the present invention is usually arranged in the equipment compartment under the aircraft, connected to the oxygen supply end pipeline of the high-pressure oxygen cylinder, and uses a special connecting hose 7 to dock to realize rapid oxygen release; the aircraft safety oxygen release The device may include an oxygen release valve 1 , an oxygen release nozzle 2 , a valve 3 and a switch 5 .
[0032] Oxygen release valve 1 has intake end (as figure 1 Bottom opening shown in ) and outlet port (as shown in figure 1 top opening shown in).
[0033] Oxygen release in...

The invention relates to an airplane oxygen system guaranteeing and maintaining technology, in particular to a safety oxygen release device for an airplane. The airplane oxygen system guaranteeing and maintaining technology aims at solving the problem that an existing oxygen release manner is poor in stability and not convenient to use. The oxygen release device comprises an oxygen release valve, an oxygen release connecting nozzle, a valve, a pushing rod and a switch. The oxygen release nozzle is arranged at the gas outflow end of the oxygen release valve in a sealed manner. The valve is arranged at a gas outflow port of the oxygen release valve, movably abuts against an air inflow end port of the oxygen release connecting nozzle through a first spring and is used for sealing the air inflow end port of the oxygen release connecting nozzle. The pushing rod is arranged in the oxygen release connecting nozzle through a second spring, extends out towards the gas inflow end port of the oxygen release connecting nozzle and is used for ejecting the valve to be open. The switch is arranged at the gas inflow end of the oxygen release valve. The safety oxygen release device for the airplane is located in a lower equipment compartment of the airplane, and is good in reachability. Besides, the integrated design of the switch and the check valve is adopted; the safety oxygen release device for the airplane is small in size and high in reliability; oxygen is released in a fast butt joint manner; and operation is convenient.
Description
technical field [0001] The invention relates to an aircraft oxygen system guarantee and maintenance technology, in particular to an aircraft safety oxygen release device. Background technique [0002] The high-pressure oxygen cylinder on the aircraft is generally fixed in the lower equipment compartment of the aircraft as an oxygen source, and the oxygen is supplied to the pilot for breathing through the oxygen switch, pipeline and oxygen equipment. When the oxygen system is maintained, repaired or regularly inspected, it is necessary to release the oxygen in the system first. At present, there are mainly three methods of oxygen release in the aircraft: disconnecting the oxygen supply pipeline in the cockpit, installing an air release valve in the cockpit, and setting an oxygen release port outside the aircraft. The first two are suitable for fighter jets, and the third is suitable for transport aircraft. Wait for a large plane. [0003] Disconnecting the oxygen supply pip...
