An oxygen supply apparatus for underground shelter

Abstract

The invention relates to an oxygen supply apparatus for underground shelter. Currently, there are no factories producing such oxygen supply apparatuses for underground shelter. The oxygen supply apparatus comprises: an oxygen bottle(1), of which an oxygen outlet is connected with a pressure-reducing valve(3); a hyperbaric oxygen pressure gauge(2) and a low-pressured oxygen pressure gauge one(4) both of which are connected with the pressure-reducing valve; a noise-reducing pipeline(6) which is also connected with the pressure-reducing valve(3); a low-pressured oxygen pressure gauge two(5) which is connected with the noise-reducing pipeline; a stop valve(7)which is connected with the low-pressured oxygen pressure gauge two; a flow meter(8) which is connected with the said stop valve; and an oxygen outlet(9) which is connected with the said flow meter. The present product can be applied in the underground shelter.
