Abstract
The utility model provides an ability automatically regulated's air is from hydraulic buffer stop, includes one casing (1) that has air inlet (1a) and gas outlet (1b), sensing element (3) link to each other with casing (1) through the screw thread of one end to through lock nut (2) locking, sensing element (3) other end passes through the screw thread and valve (4) link to each other, sensing element (3) comprise the vacuum diaphragm chamber. The utility model discloses can change along with cabin altitude, automatically regulated intake air's content better has satisfied human physiology hygiene index, need not at the during operation manual, operating is simplified, simple compact, small, light in weight, reliability height, longe -lived.
Description
Technical field
This utility model belongs to airborne oxygen-supplying technology, relates to sucking airborne oxygen system air content regulation
The improvement of mechanism.
Background technology
It is check valve mechanism that current airborne oxygen system controls to suck the mechanism of air content, and structure is former
Reason sees Figure of description 1, and it includes the housing 104 with air inlet 104a and venthole 104b and installs
Check valve 102, spring 103, valve pad 105 and switch knob 101 in housing 104.
Its operation principle is:
When cabin altitude is less than 4km, or when in oxygen cylinder, oxygen is inadequate, flight attendant manual unlocking is opened
Closing handle 101, check valve 102 leaves valve pad 105, outside air under the drive of switch knob 101
Enter housing 104 by air inlet 104a, and flow out through venthole 104b；When need not suck air,
Closing switch handle 101, check valve 102 compresses valve pad 105 under the active force of spring 103, extraneous
Air can not pass through venthole 104b.
There is problems with in this structure, and 1, need flight attendant manual operation, intelligence not, in special feelings
Potential safety hazard can be caused under condition；2, suck air content to immobilize, it is impossible to on-demand regulation.
Utility model content
The purpose of this utility model is: proposes one and has according to cabin altitude, is automatically adjusted suction air
Content, Human Physiology Hygienic Index can be better met.
The technical solution of the utility model is: a kind of air automation that can be automatically adjusted, including a band
The housing 1 of air inlet 1a and gas outlet 1b, sensing element 3 is had to be connected with housing 1 by the screw thread of one end,
And locked by locking nut 2, sensing element 3 other end is connected with valve 4 by screw thread；Sensitive unit
Part 3 is made up of aneroid capsule group.
Further, above-mentioned valve 4 cross section is trapezoidal.
Its operation principle is that the pressure reduction that aneroid capsule impression causes because cabin altitude raises reduces, and makes self to indulge
To expansion, drive the valve 4 being arranged on sensing element 3 to move, reduce the stream between the 1b of gas outlet
Logical area, and then reduce the air capacity entering from air inlet 1a and going out from gas outlet 1b；When passenger cabin is high
When degree reduces, the sensing element 3 being made up of aneroid capsule group, experience because cabin altitude reduces the pressure reduction caused
Increase, make self longitudinal contraction, drive the valve 4 being arranged on sensing element 3 to move, increase and go out
Circulation area between QI KOU 1b, and then increase the sky entering from air inlet 1a and going out from gas outlet 1b
Tolerance, it is achieved be automatically adjusted suction air content.
The utility model has the advantages that: this utility model can change with cabin altitude, is automatically adjusted suction
The content of air, has better met Human Physiology Hygienic Index, operationally without manually, has simplified
Operation, the compactest, volume is little, lightweight, reliability is high, the life-span is long.
Accompanying drawing explanation
Fig. 1 is the structural principle that existing airborne oxygen system controls to suck the check valve mechanism of air content
Schematic diagram；
Fig. 2 is structural principle schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in further details.See Fig. 2, Yi Zhongneng
The air automation being automatically adjusted, including a housing 1 with air inlet 1a and gas outlet 1b, sensitive
Element 3 is connected with housing 1 by the screw thread of one end, and is locked by locking nut 2, sensing element 3
The other end is connected with valve 4 by screw thread；Sensing element 3 is made up of aneroid capsule group.
Aneroid capsule group has the characteristic with height change convergent-divergent, when specific works, and aneroid capsule
The sensing element 3 of group composition, experiences and reduces because cabin altitude raises the pressure reduction caused, make self longitudinal dilatation,
Drive the valve 4 being arranged on sensing element 3 to move, reduce the circulation area between the 1b of gas outlet,
And then reduce the air capacity entering from air inlet 1a and going out from gas outlet 1b；When cabin altitude reduces,
The sensing element 3 being made up of aneroid capsule group, experiences and increases because cabin altitude reduces the pressure reduction caused, make certainly
Body longitudinal contraction, drives the valve 4 being arranged on sensing element 3 to move, increases between the 1b of gas outlet
Circulation area, and then increase and enter and the air capacity gone out from gas outlet 1b from air inlet 1a, it is achieved
It is automatically adjusted suction air content.
Further, above-mentioned valve 4 cross section is trapezoidal, and the air regulation that can make gas outlet is more flat
Slow, more conform to the human body demand to air.
Claims (2)
1. the air automation that a kind can be automatically adjusted, it is characterized in that: include the housing (1) with air inlet (1a) and gas outlet (1b), sensing element (3) is connected with housing (1) by the screw thread of one end, and locked by locking nut (2), sensing element (3) other end is connected with valve (4) by screw thread；Sensing element (3) is made up of aneroid capsule group.
The air automation that can be automatically adjusted the most according to claim 1, it is characterised in that: valve (4) cross section is trapezoidal.
