As shown in fig. 1-6, in use, an air supply system of a motorized rescue capsule has a plurality of modes of operation, including, in particular, the following:
when a person in the transport cabin 1 needs to breathe by using oxygen in the transport cabin 1, the first connecting ball valve 701 is closed, and the ball valve G306 is opened, so that the oxygen in the gas supply and storage bottle 301 sequentially passes through the second gas supply and pressure reducing valve 302, the quick connector B303, the ball valve F304, the stop valve C305, the ball valve G306, the flowmeter 307, the one-way valve B308, the ball valve H309 and the silencer B310 to enter the transport cabin 1.
When the person in the transfer cabin 1 needs to breathe the mixed gas by using the mask 209, the stop valve A203 is opened, the first connecting ball valve 701 is closed, and the ball valve E212 is closed, so that the breathing air supply pipeline 2 and the cabin air supply pipeline 3 cannot be communicated and are relatively independent. The ball valve A202 is opened, so that the mixed gas in the pressure regulating gas storage bottle 501 enters the breathing gas supply pipeline through the breathing gas source pipeline 9, and sequentially enters the mask 209 after passing through the ball valve A202, the stop valve A203, the first gas supply pressure reducing valve 204, the ball valve B205, the ball valve C206, the manifold 207 and the ball valve D208.
When a person in the transport pod 1 needs to breathe oxygen by using the mask 209, the ball valve G306 is closed, the first connecting ball valve 701 is opened, the ball valve E212 is closed, and the stop valve a 203 is closed, so that oxygen in the gas supply bomb 301 sequentially passes through the second gas supply pressure reducing valve 302, the quick connector B303, the ball valve F304, the stop valve C305, the first connecting ball valve 701, the first gas supply pressure reducing valve 204, the ball valve B205, the ball valve C206, the manifold 207, and the ball valve D208 and then enters the mask 209.
In addition, when the person in the transfer cabin 1 breathes the mixed gas by using the mask 209 and then breathes the oxygen by using the mask 209, the ball valve E212 is opened, so that the residual mixed gas in the pipeline is discharged through the ball valve E212, the check valve a 213 and the silencer a 214 in sequence, and then the oxygen supply is performed by using the gas supply bomb 301.
Breathe exhaust pipe 6 and face guard 209 end intercommunication of giving vent to anger for exhaust gas exhaled in the face guard 209, specific face guard 209, ball valve N601, ball valve P602, ball valve Q603, tee bend cut-off ball valve 604, back pressure regulator 605 communicate in proper order, wherein ball valve Q603, tee bend cut-off ball valve 604, back pressure regulator 605 set up outside transporting cabin 1, make the exhaust gas exhaled in the face guard 209 discharge transport cabin 1 outside. In addition, the ball valve S607 is disposed in the transfer chamber 1, and the ball valve S607, the ball valve R606 and the back pressure regulator 605 are sequentially connected, so that the pressure of the exhaust gas exhaled from the mask 209 is consistent with the pressure in the transfer chamber 1, thereby ensuring smooth emission of the exhaled exhaust gas from the mask 209.
When the pressure in the transfer cabin 1 needs to be maintained or controlled, the second connecting ball valve 801 is closed, the ball valve K409 is closed, the quick connector C401 is connected with an external air source pipeline, and air sequentially passes through the quick connector C401, the ball valve I402, the stop valve E403, the one-way valve C404, the ball valve J405 and the silencer C406, and enters the transfer cabin 1 from the silencer C406.

The two groups of pipelines form one device, so that the guarantee of maintaining or controlling the internal pressure of the transfer cabin 1 is improved.
When the pressure in the transferring cabin 1 is smaller than the set pressure, the movable pressure compensation is needed, the second connecting ball valve 801 is closed, the ball valve A202 is closed, so that the gas in the pressure regulating gas storage bottle 501 can sequentially pass through the pressure regulating and reducing valve 502, the quick connector E503, the ball valve L504, the stop valve H507, the one-way valve D508, the ball valve M509 and the silencer D510, and enter the transferring cabin 1 through the silencer D510 for pressure compensation in the transferring cabin 1.
