Description
Technical field:
The invention belongs to aviation ejection escape fields, and in particular to a kind of from airtight component.
Background technique:
In order to realize function that ejector seat is docked with aircraft interface automatic plug, it is desirable that have at pipe interface from airtight group
Part；The component will guarantee that gas flows smoothly no blocking after interface grafting, guarantee the sealing of interface after ejection separation.
Technical solution:
The purpose of the present invention: providing a kind of from airtight component, and gas flows smoothly no blocking, interface after guaranteeing interface grafting
Guarantee the automatic-sealed of interface after separation.
Technical solution of the present invention: a kind of from outside airtight component, including guide cover 1, spring 2, piston 3 and nozzle 4, pipeline
Shell 5, O-ring seal 8；Guide cover 1, spring 2, piston 3 are sequentially arranged at the interior intracavitary of pipeline shell 5, and O-ring seal 8 is installed
In 5 seal groove of pipeline shell；Piston 3 can move up and down in guide cover 1, and cooperate with O-ring seal 8, and nozzle 4 passes through
Nut 6 is locked on sliding rail underbeam 7, and nozzle 4 is plugged into the hole of pipeline shell 5, is cooperated with O-ring seal 8, is opened piston 3.
The pipeline shell 5 is the structure with vertical direction cross bore, and inner cavity is equipped with square crossing venthole, in level
The lower end of direction venthole is set there are two seal groove.
The guide cover 1 is with guiding, the structure of sealing function, and seal groove is arranged at top, and leading with gas vent is arranged at lower part
Xiang Kong.
The piston 3 is with guiding, ventilates, the structure of sealing function, and guide post is arranged at top, and middle part has with positive stop lug boss
The air channel of three push rod structure is arranged at sealing cylinder, lower part.
After the nozzle 4 is plugged on pipeline shell 5, piston 3 opens interface under the promotion of nozzle 4, grafting in place
Afterwards, ejector seat is automatic locking.
Beneficial effects of the present invention: the present invention can effectively solve the circulation problem of fast insert-pull pipe interface and automatic close
Envelope problem, structure are simple；By carrying out Transform Type design to the present invention, transplantability is stronger, may be used on various fast insert-pull pipelines
On interface.
Detailed description of the invention:
Fig. 1 is from airtight component composition figure；
Fig. 2 is pipe interface plugboard chart；
Fig. 3 is pipe interface separation figure.
Wherein, 1- guide cover 2- spring 3- piston 4- nozzle 5- pipeline shell, 6- nut, 7- sliding rail underbeam
Specific embodiment:
The present invention will be further described with reference to the accompanying drawings and examples.As shown in Figure 1, the present invention is from airtight component packet
Include guide cover 1, spring 2, piston 3 and nozzle 4.When guide cover 1, spring 2, piston 3 are sequentially arranged on pipeline shell 5, piston 3
It can move up and down in guide cover 1, realize unlatching, the closure function of pipe interface.When unlatching, by piston 3 distinctive appearance and
Interface form ensure that the gas flow area of interface is not less than the circulation area of nozzle 4, to guarantee to flow smoothly without stifled
Plug；When closure, the O-ring seal of 5 interface of pipeline shell is compressed by the cylindrical surface of piston 3, guarantees leakproofness.
As shown in Fig. 2, nozzle 4 is locked on sliding rail underbeam 7 by nut 6, it is living after nozzle 4 is plugged on pipeline shell 5
Plug 3 opens interface under the promotion of nozzle 4, and after grafting in place, ejector seat is automatic locking, and nozzle 4 and pipeline shell 5 are reliable
Grafting guarantees the smooth circulation of gas by the distinctive appearance and interface form of piston 3.
As shown in figure 3, nozzle 4 is separated with pipeline shell 5 after ejection, gas of the piston 3 in spring 2 and pipeline shell 5
It is pushed closed interface under body pressure collective effect, after being kept completely separate, the cylindrical surface of piston 3 compresses 5 interface of pipeline shell
O-ring seal 8, realize automatic-sealed.
