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.
Description
Technical field: [0001] The invention relates to an oxygen supply device for an underground shelter. Background technique: [0002] The current oxygen supply methods can be divided into two types: storage oxygen supply and oxygen production. Among them, the storage type oxygen supply includes high-pressure oxygen cylinder storage, liquid oxygen storage and critical oxygen storage; oxygen production mainly includes water electrolysis oxygen production and chemical oxygen production. High-pressure oxygen supply has simple structure, mature technology and low environmental requirements; liquid oxygen storage and critical oxygen storage have complex structures and are not suitable for high-temperature environments; oxygen production by electrolysis of water has mature technology, high complexity, and requires electricity; chemical Oxygen production is a mature technology with high complexity and generates a lot of heat. At present, there is no manufacturer that produces and se...
