Description
Technical field
The present invention relates to the emergent disconnection self sealing structure of one kind, self sealss after oil circuit are cut off when being hit more particularly to aircraft pendant
Pipeline structure, specially a kind of aircraft emergency protecting equipment self sealss falling-off connector.
Background technology
It is helicopter in the case of pendant is hit that self sealss falling-off connector, which is, protects oil feed line, closing oil path, reduces fuel feed pump
The demand of fuel leakage in road and develop.As China's aviation industry continues to develop, helicopter species is on the increase, from close
Simultaneously extensive use will be continued to develop by sealing falling-off connector structure.
Goal of the invention or technical problems to be solved
Self sealss falling-off connector is fuel oil end face seal structure.Product technology requires high, long lifespan, should ensure that product connects
Path when connecing, ensure seal request after product separation again, sealing structure is closed flexible used by this is required, close after closing
Envelope is reliable.
The content of the invention
The present invention use two adapter assemblies, and with rivet interlacement, and during by axial force, what two adapter assemblies connected breaks
Rivet is broken, and during by radial load, the curved disconnected rivet fracture of two adapter assemblies connections, the adapter assembly junction of product two is designed as
It is emergent to disconnect overload protection；Simultaneously after two adapter assembly separation, valve is rotated by 90 ° sealing in the presence of torsion spring power around small axle
Valve holder assembly, so as to ensure that self sealss are more reliable.
The sealing structure of product is ingenious, and it is a path that two adapter assemblies, which link together, after the separation of two adapter assemblies each
Sealing.Valve, which rotates, to ensure sealing again flexibly, in place.To ensure properties of product and reliability, this require valve,
Valve base has higher size, shape, positional precision and surface roughness.
The adapter assembly junction of product two is designed as emergent disconnection overload protection, and this requires product in design, connection
The selection of place's material, intensity index will meet to break load, bending load requirement, need to do substantial amounts of verification experimental verification and work.
Increase failure identification structure.Product is bent or during torsional load, and failure identification plate can occur distortion at first and become
Shape or fracture, so as to reflect product exception, product should shift immediately.
Technical scheme
A kind of aircraft emergency protecting equipment self sealss falling-off connector, is made up of adapter assembly I, adapter assembly II,
Adapter assembly I is by adapter nozzle A (2), packing ring (3), sealing ring A (4), plug screw (5), spring (6), swivel nut (7), rectangle

Component A (11) is mounted in the bottom of swivel nut (7), then loads onto spring (6), opens valve (22), and valve (22) overcomes torsion spring (23)
Active force, be turned to horizontal level, screw on plug screw (5), the left side of the right side stop valve (22) of plug screw (5), adapter
Nozzle A (2) is connected through a screw thread with swivel nut (7), plug screw (5) and swivel nut (7) again by threaded connection,
Adapter assembly II is by packing ring (3), sealing ring A (4), plug screw (5), spring (6), rectangular seal (10), sealing ring B
(13), valve holder assembly B (14), adapter nozzle B (18), sealing ring (19), locking swivel nut (20), adapter nozzle set (21), valve
(22), torsion spring (23), pin (24) composition, swivel nut (1) is put into by valve holder assembly B (11), is loading onto spring (6), rotation is lived
Door (22), overcomes torsion spring (23) elastic force, valve (22) is in horizontality, be screwed into plug screw (5), will take over nozzle set (21) and be mounted in
On adapter nozzle B (18), tightened with locking swivel nut (20) by screw thread, will take over nozzle set (21) and be screwed on swivel nut (1), use clamp screw
Follow closely (15) locked adapter nozzle set (21).Adapter assembly I is connected with adapter assembly II by adapter sleeve (12), failure identification plate (8)
Pass through rivet interlacement with sheath.
Valve holder assembly A (11) draws back after adapter assembly I disconnects with adapter assembly II, and valve (22) is in torsion spring (23)
In the presence of close with valve holder assembly A (11) seal.
Valve holder assembly B (14) draws back after adapter assembly I disconnects with adapter assembly II, and valve (22) is in torsion spring (23)
In the presence of close with valve holder assembly A (11) seal.
Working condition
Valve (22) overcomes the active force of torsion spring (23) to be rotated by 90 ° around small axle (24) during work, and work is blocked by plug screw (5)
Door keeps this state, ensures oil feed line normal open, and adapter nozzle A (2) and adapter nozzle B (18) are connected with fuel pipe on aircraft, with
Aircraft pipeline forms path.
Beneficial effect
The invention provides a kind of tape jam to identify self sealss falling-off connector structure, and product seals more reliable and failure mark
Knowing plate energy pre-tip has anomaly, improves reliability, the security of product.Self-sealed falling-off connector is oil feed line
In most weak part, when fuel system is by survivable shock (pendant collides land), self-sealed falling-off connector is emergent to be disconnected,
Automatic-sealed fuel pipe and fuel tank.So that aircraft improves security in the case of pendant is hit.It is former according to the structure of the product
Deisgn product is managed, can also be applied in the other systems of emergent disjunction self sealss.
Moved forward under the action of the spring when the separation of two adapter assemblies I, II, valve holder assembly when pendant is hit occur for aircraft,
Valve departs from plug screw simultaneously, and valve is rotated by 90 ° sealing active door holder assembly in the presence of torsion spring power around small axle, realizes emergent disconnect
Self-sealing function.
