Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below.Referring to Fig. 1, a kind of aircraft oxygen system is connected with unidirectional three
Head, it is characterised in that：It is by housing 1, branch pipe 2, the 1st filter screen 3, the 1st check valve component 4, the 2nd filter screen 5 and the 2nd check valve
Component 6 is constituted；Have the arrow of a horizontal direction outside the housing (1), have in housing 1 horizontal hole and one it is vertical
Hole, the inner port of upright opening connection orthogonal with the middle part of horizontal hole, under the left port and upright opening of horizontal hole
There is internal thread port, has external screw thread in the right-hand member of horizontal hole, has external screw thread outside the lower port of upright opening, with interior
1st check valve component 4 of screw thread is combined with the external screw thread of horizontal hole right-hand member, by the 1st check valve component 4 and housing 1
Right-hand member be connected as entirety；Combined with externally threaded 2nd check valve component 6 with the internal thread of horizontal hole left end, will
The left end of 2nd check valve component 6 and housing 1 is connected as entirety；1st filter screen 3 is arranged on the runner of the 1st check valve component 4
Interior, the 2nd filter screen 5 is arranged in the runner of the 2nd check valve component 6；Branch pipe 2 is that a upper end carries externally threaded pipe, branch
The external screw thread of the upper end of pipe 2 is screwed into the internal thread of upright opening lower port.
In order to accelerate the speed that oxygen flows into oxygen cylinder, the horn mouth expanded outwardly is carried in the lower end of described branch pipe 2.
In order to increase the circulation area between branch pipe 2 and oxygen cylinder inner chamber and prevent the problems such as single face is blocked, in described branch pipe 2
There is radial hole on tube wall.
Operation principle of the present utility model is：A kind of unidirectional three-way connection of aircraft oxygen system, it is characterised in that：It by
Housing 1, branch pipe 2, the 1st filter screen 3, the 1st check valve component 4, the 2nd filter screen 5 and the 2nd check valve component 6 are constituted.Unidirectional threeway
After joint is completed, the 1st check valve component 4 is connected with oxygen air induction conduit according to direction shown in the outer arrow of housing 1, will
2nd check valve component 6 is connected with oxygen exhaust manifolds, and the external screw thread of the upright opening lower port of housing 1 is connected with oxygen cylinder.When
After source of the gas enters the 1st check valve component 4 through air induction conduit, the spring inside the 1st check valve component 4 occurs for bleed pressure
Elastic deformation, valve is opened, and oxygen is flowed in oxygen cylinder or through the flow direction oxygen terminal of the 2nd check valve component 6 or next oxygen
Gas cylinder, this is aerobic process；When occupant is opened with oxygen terminal on machine, source of the gas flows to the 2nd check valve component 6 by branch pipe 2,
Bleed pressure makes the spring inside the 2nd check valve component 6 occur elastic deformation, and valve is opened, and oxygen flow direction uses oxygen terminal, this
For oxygen supply process.
