Four, adopt the panel type flow meter to regulate gas flow, realize the purpose of quantitative oxygen supply, effectively keep the suitable air ambient in survival capsule.
Five, adopt noise damper to carry out noise reduction to air-flow, for the hedging personnel provide suitable hedging environment.
Description of drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is that box body, 2 is that oxygen supply interface, 3 is that main control valve, 4 is that threeway, 5 is that oxygen manometer, 6 is that flow meter, 7 is noise damper.
The specific embodiment
As shown in Figure 1, a kind of oxygen supply of the utility model unit, described oxygen supply unit is arranged on box body 1, the arrival end of oxygen supply unit is provided with oxygen supply interface 2, the port of export of described oxygen supply interface 2 is connected with the entrance point of main control valve 3, the port of export of described main control valve 3 is connected with the A end of threeway 4, and the B end of described threeway 4 is connected with flow meter 6, and the C end of described threeway 4 is connected with oxygen manometer 5.
The entrance point of above-mentioned oxygen supply interface 2 can be connected with the oxygen system pipeline of outside, the main control valve 3 that is connected with the port of export of oxygen supply interface 2 is used for controlling the break-make of ventilation channel, and the threeway 4 that is connected with main control valve 3 is divided into two-way with the interal supplying oxygen pipeline, one tunnel is connected with flow meter 6, and oxygen flow is controlled; Another road is connected with oxygen manometer 5, is used for measuring oxygen pressure.
Further, described flow meter 6 also is connected with the noise damper 7 that oxygen flow is carried out noise reduction.
Further, described flow meter 6 is the panel type flow meter, is convenient to observe and control.
Above-mentioned main control valve 3, threeway 4, oxygen manometer 5 and panel type flow meter 6 all are arranged on the front panel of box body 1, convenient operation and observation; Noise damper 7 is arranged in the top of box body 1, and oxygen supply interface 2 is arranged on the bottom of box body 1.
Above-mentioned oxygen supply unit is applicable to refuge chamber or the survival capsule under coal mine, is used to the hedging personnel to build the air ambient of suitable hedging, and its each ingredient all meets the safety of coal mines regulation.
The above is explained in detail the specific embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited in above-described embodiment, in the ken that those of ordinary skills possess, can also make a variety of changes under the prerequisite that does not break away from the utility model aim; The position of each ingredient on box body in those skilled in the art's capable of regulating the utility model for example.
