System easily and safely operates, and improves the maintainability of oxygen system.
The utility model to achieve the goals above, adopts the following technical scheme that
A kind of to put oxygen valve for aircraft, tightening cap nut and shell are tightened by nut bottom end realizes connection,
Cap nut is tightened after connection can rotate and will not be detached from shell；
Spring, valve bar and valve base are installed in the upper end of shell in order, are closely connected valve base using clamp nut
On shell, design has sealing ring between valve base and clamp nut.
Further, clamp nut is to put oxygen valve outlet side, outlet is blocked by blocking cap and chain when not working, from oxygen
Valve bar is pressed on valve base by the oxygen that air cock comes, and realization is airtight, and oxygen end interface under shell enters main oxygen system
System.
Further, when putting oxygen operation, blocking cap is unscrewed, puts the deflation of oxygen valve with oxygen equipment hose connection clamp nut is put
It holds, opens valve bar with thimble on equipment flexible axle, valve bar is disengaged with valve base, and oxygen is i.e. from valve bar and valve base
Between gap enter equipment and put oxygen hose, oxygen operation is put in realization.
Further, the material of sealing ring is brass.
Further, shell connection oxygen switch outlet end is pipe screw thread.
Further, tightening cap nut is three-way pipe structure.
Originally oxygen valve scheme is put suitable for aircraft oxygen system, and metal material is typically chosen brass, and nonmetallic materials are selected
Polytetrafluoroethylene (PTFE), screw thread are all made of G1/4 pipe screw thread.
For putting oxygen valve, this programme uses the structure type with cap nut tee tube and check valve.It is convenient to consider
It on machine plus reequips, is designed using band cap nut tee tube, cap nut can connect with oxygen switch outlet end, former and oxygen
Switch connection conduit can directly with put oxygen valve and connect.
The other end of air bleed valve is designed as check valve structure, which has valve bar, valve base and groups of springs
At check valve is connected by clamp nut, is sealed between clamp nut and valve base using sealing ring.Valve bar is by shaft and gathers
Sealing is realized in tetrafluoroethene block crimping composition, the contact by valve bar with valve base.The clamp nut other end is connected using blocking cap
It connects, blocking cap and clamp nut are tethered at using chain.
Band chain blocking cap is unscrewed first when to realize to put oxygen function and be, is put oxygen equipment hose using dedicated and is put oxygen valve
It connects, the thimble being had in equipment, thimble jacking block valve bar, oxygen is discarded to outside machine by hose from thimble gap location, can be led to
Cross oxygen switch control oxygen discharging speed.
The beneficial effects of the utility model
The utility model is able to achieve oxygen system and puts oxygen function, puts oxygen valve function and meets routine use air-tightness requirement,
Blocking cap connection is only unscrewed when putting oxygen puts oxygen hose, it is easy to operate.The oxygen of releasing is put by putting oxygen hose to outside machine, is kept away
Exempt from pure oxygen in high pressure to put to equipment compartment and the oxygen rich gas of cockpit bleed accumulation risk.The utility model makes oxygen system put oxygen
Without lifting the work such as seat and disassembly console side plate, the workload of ground crew is enormously simplified, and a whole people is just
It can operate, improve the maintainability of aircraft.
The utility model using tightening cap nut structure design, can be convenient to oxygen switch original on machine and pipe
Road, which carries out putting oxygen valve, adds repacking, it is only necessary to disconnect machine upper pipeline, oxygen valve will be put and connect with oxygen switch, former disconnection pipeline and
The connection of oxygen valve is put, system installation is simplified.
