Description
Technical field
The utility model relates to the adjustable air lance device of a kind of airflow direction, belongs to plane environmental control system.
Background technique
At present, a lot of fighter, the waist air lance of trainer aircraft environmental control system cabin air distribution system can not regulate direction, air-flow directly blows facing to pilot always, pilot's health both sides are made to produce local overcooling or overheated sensation, reduce the travelling comfort of pilot, thus affect pilot's working efficiency.
Summary of the invention
In order to overcome above-mentioned defect, the purpose of this utility model is with waist air lance in aircraft environmental control system passenger cabin for object, by Optimization analyses, provides a kind of airflow direction adjustable air lance device, thus improve pilot's Thermal comfort, improve pilot's working efficiency.
To achieve these goals, the utility model adopts following technological scheme:
The adjustable air lance device of a kind of airflow direction, it comprises air lance, threeway outer sleeve, seal ring I and seal ring II, swivel becket, limited ring, pad I, pad II, retaining ring assembly;
Air lance passes threeway outer sleeve and rotates in threeway outer sleeve;
Threeway outer sleeve has a position-limitting mouth;
Seal ring I and seal ring II is had between threeway outer sleeve and air lance;
Air lance has two retaining ring assemblies.
Retaining ring assembly is made up of felt, spring sheet, retaining ring, fixing hoop, screw.
The material of seal ring I and seal ring II, pad I, pad II is rubber material or polytetrafluoroethylmaterial material.
The beneficial effects of the utility model: the utility model, by regulating the airflow direction of air lance, improves the travelling comfort of pilot, contribute to the working efficiency improving pilot.And it is high that the utility model has reliability, cost is low, simple to operate, little, the convenient disassembly of taking up room, is convenient to the features such as maintenance.
Accompanying drawing explanation
The structural representation of the air lance that Fig. 1 uses for current aircraft environmental control system;
Fig. 2 is structural representation of the present utility model;
Fig. 3 be the utility model threeway outer sleeve partly cut open figure;
Fig. 4 be the utility model retaining ring assembly partly cut open figure.
Embodiment
Be described in detail below in conjunction with accompanying drawing 1 ~ 4 pair of the utility model:
The adjustable air lance device of a kind of airflow direction, it comprises air lance 1, threeway outer sleeve 5, seal ring I 9 and seal ring II 10, swivel becket 7, limited ring 3, pad I 4, pad II 6, retaining ring assembly 2;
Air lance 1 passes threeway outer sleeve 5 and rotates in threeway outer sleeve 5;
Threeway outer sleeve 5 has a position-limitting mouth; For limiting the rotation angle of air lance.
Seal ring I 9 and seal ring II 10 is had between threeway outer sleeve 5 and air lance 1; Have and prevent Leakage Gas, avoid the effect producing noise.
Air lance 1 has two retaining ring assemblies 2.
Retaining ring assembly 2 is made up of felt 11, spring sheet 12, retaining ring 13, fixing hoop 14, screw 15.
1., by fixing hoop, air lance is fixed structurally.
2., retaining ring can make air lance can rotate in ring set.
3., under the effect of spring sheet and felt, when air lance can be made to rotate, there is certain frictional force, make it have the ability remained in sense of rotation.
The material of seal ring I 9 and seal ring II 10, pad I 4, pad II 6 is rubber material or polytetrafluoroethylmaterial material.
