Description
Technical field
The present invention relates to the oxygen supply equipment of pilot, and pressure-regulating device is supplied oxygen more specifically to one kind.
Background technology
At present, the oxygen mask and pressure breathing jerkin that China fighter pilot uses supply oxygen respectively, each own independent confession
Oxygen pipeline.The ventilation channel of oxygen mask and pressure breathing jerkin is independently controlled, and oxygen mask is adjusted according to environmental pressure
Supply oxygen pressure and the blowing pressure of pressure breathing jerkin.Two sets of ventilation channels are set to cause oxygen system to complicate in the prior art,
Pilot's burden is added, and it is fragile, and maintenance cost is high.
The content of the invention
The technical problem to be solved in the present invention is, there is provided one kind oxygen supply pressure-regulating device come be oxygen mask simultaneously with
Pressure breathing jerkin supplies oxygen, and meets flight protective demand, and simplify ventilation channel.
The technical solution adopted for the present invention to solve the technical problems is：A kind of oxygen supply pressure-regulating device of construction, including
Housing, diaphragm, valve base, valve plate, adjusting nut, three-way pipe and the first spring, three mouths of the three-way pipe connect respectively
Oxygenregulator, oxygen mask and the housing, the lower end connection pressure breathing jerkin of the housing, the upper end of the valve base passes through
Diaphragm is connected with the housing, and the valve plate is arranged on the lower end exit of the valve base, and the adjusting nut is fixed on
The enclosure interior, the valve plate insert adjusting nut and coordinated with adjusting nut gap, and first spring is arranged on institute
State between valve plate and the adjusting nut, the housing is provided with pressure relief opening；
When system is in non-pressurised oxygen supply state, the valve plate blocks the lower end outlet of valve base, and oxygenregulator is only
Supplied oxygen to oxygen mask；
When system is in pressure breathing oxygen state, the valve plate is moved down, and the first spring is compressed, the lower end of valve base
Outlet is opened, and pressure relief opening is in closed state, and oxygenregulator supplies oxygen to oxygen mask and pressure breathing jerkin simultaneously；
After pressure breathing oxygen process terminates, pressure is moved upward to higher than pressure in ventilation channel, valve plate in pressure breathing jerkin
The lower outlet of valve base is blocked, valve base is moved up, and pressure relief opening is opened, and the oxygen in pressure breathing jerkin is released by pressure relief opening.
In such scheme, the upper end of the valve base is also connected by second spring with the housing.
In such scheme, the adjusting nut is threadedly coupled with the housing, and the adjusting nut is provided with external screw thread, institute
State housing and be provided with internal thread.
Implement the oxygen supply pressure-regulating device of the present invention, have the advantages that：
Oxygenregulator to oxygen mask input pressure more than 0.5kPa when, be filled with oxygen to pressure breathing jerkin；Oxygen mask
When input pressure maintains a pressure, isobaric oxygen is inputted to pressure breathing jerkin；When oxygen mask input pressure declines, the compensatory back of the body
Heart pressure release, and remain consistent with mask pressure.Present invention oxygen supply pressure-regulating device is meeting high maneuverability energy and counterpressure
Protection on the basis of, can largely simplify aircraft ventilation channel, mitigate pilot's burden.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing：
Fig. 1 is to supply oxygen schematic diagram when pressure-regulating device is in non-pressurised oxygen supply state；
Fig. 2 is to supply oxygen schematic diagram when pressure-regulating device is in pressure breathing oxygen state；
Fig. 3 is to supply oxygen the schematic diagram at the end of pressure-regulating device is in pressure breathing oxygen state.
Embodiment
In order to which technical characteristic, purpose and the effect of the present invention is more clearly understood, now compares accompanying drawing and describe in detail
The embodiment of the present invention.
As shown in figure 1, present invention oxygen supply pressure-regulating device includes housing 1, diaphragm 2, valve base 3, valve plate 4, regulation
