Description
Technical field
The present invention relates to outdoor gear technical field, and in particular to a kind of Portable oxygen cylinder.
Background technology
It is well known that oxygen is gas for the survival of mankind；In recent years, with vehicle exhaust, the discharge of industrial waste gas,
Air ambient is more and more severe, and haze weather is constantly aggravated, and the pure oxygen in breathing nature has turned into a kind of extravagant hope；People
Easily trigger acute upper respiratory infection, acute tracheal bronchus pneumonia, pulmonary heart disease, asthma attack in bad air environment；It is low
Oxygen aggravates blood circulation disorder, induces the hair of the cardiovascular and cerebrovascular diseases such as angina pectoris, myocardial infarction, hypertension, cerebral hemorrhage, coronary heart disease
Make, life-threatening safety；Oxygen uptake can correct the anaerobic condition of body as a kind of important emergency measures, hinder for alleviating
Patient's hypoxic conditions are particularly significant, meanwhile, can the sick and wounded inhale in time at " gold 1 hour " or " platinum ten minutes " for the treatment of
Oxygen, is to reduce percentage of died of wound, improves the key factor of in-situ curing ability.Therefore, it can the Portable oxygen cylinder carried with just
Arise at the historic moment, but the gas flow that traditional Portable oxygen cylinder is carried is too small, can not in case of emergency meet needs.
Publication No. CN204582205U, publication date is 20150826 Chinese invention patent, discloses a kind of Cardiological
Patient's Portable oxygen cylinder, including cylindrical tank, the height of the tank body is 20cm, and basal diameter is 10cm；The tank
Body top is provided with air-out mechanism, and one end of the air-out mechanism connect with the tank body, the other end and oxygen face mask clamping；Institute
The bottom for stating tank body is provided with inflation mechanism to supplemental oxygen.
The Portable oxygen cylinder oxygen storage capacity is few, it is impossible to meets the oxygen absorbed of in emergency circumstances patient, generally requires many bottles of oxygen
Gas could meet a personal use.
The content of the invention
It is an object of the present invention to be directed to problems of the prior art, propose a kind of big oxygen storage capacity, simple structure,
Easy to operate, small volume, portable Portable oxygen cylinder.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of Portable oxygen cylinder, including columned valve body and gas cylinder, valve body are fixedly connected with gas cylinder；In valve body
Pressure-regulating valve and flow control valve are provided with, low-pressure chamber is provided with the top of valve body；Described pressure-regulating valve one end and height
Body phase of calming the anger connects, and the other end is connected with flow control valve, and flow control valve one end is connected with pressure-regulating valve, the other end and low pressure
Air chamber is connected；Low-pressure chamber one end is connected with flow control valve, and the other end is provided with escaping pipe.
The pressure-regulating valve is connected by pressure piping with gases at high pressure；Pressure-regulating valve passes through low pressure pipeline and flow
Regulating valve is connected；Flow control valve is connected by low pressure pipeline with low-pressure chamber.
The bottom outside of the valve body is provided with screw thread, and the bottleneck inner side of gas cylinder is provided with screw thread, valve body and high pressure
Gas cylinder thread is connected.
The volume of the gas cylinder is 0.22-0.45 liters, and the pressure in the bottle is 30Mpa, and outlet overpressure is 0.1-
1Mpa。
The volume of the gas cylinder is 0.35 liter, and the pressure in the bottle is 30Mpa, and outlet overpressure is 0.5Mpa.
The material of the gas cylinder is high pressure resistant aluminum alloy material；The material of the valve body is high-strength aluminum alloy material
Matter.
Flowmeter is provided between the low-pressure chamber and escaping pipe.
It is provided with the body wall and fills mouth, is filled mouth and be connected with gases at high pressure by pressure piping.
Pressure gauge is additionally provided with the body wall, pressure gauge is connected by pressure piping with gases at high pressure.
Piston is provided with the pressure-regulating valve, piston one end is provided with spring, the height in the other end and high-pressure air pipe
Body of calming the anger is contacted；The low pressure gas pipe and the junction of pressure-regulating valve and the sidewall contact of piston.
The high-pressure air pipe is arranged at the middle part of valve body.
The flow control valve is needle valve.
By adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, the gases at high pressure in gas cylinder of the present invention flow through pressure-regulating valve by pressure piping, and pressure-regulating valve is by high pressure gas
Body is converted into low-pressure gas, and flow control valve is flowed through by low pressure pipeline, and be adjusted to for flow to need size by flow control valve,
Low-pressure chamber is flowed into through low pressure pipeline again, low-pressure chamber is a small-sized gas storage space, plays a part of buffer gas flow, then pass through
Escaping pipe flows out.The present invention has that oxygen storage capacity is big, simple structure, easy to operate, small volume, portable advantage.
2nd, pressure piping is used for transferring high voltage gas, and low pressure pipeline is used to transmit low-pressure gas.Because gases at high pressure are to pipe
The pressure in road is larger, therefore the intensity requirement of pressure piping is higher, and casting technique is complex, and cost is also higher.After decompression
Low-pressure gas it is smaller to the pressure of pipeline, casting technique does not have the complexity of pressure piping, and cost is relatively low, therefore intensity can be with
The requirement of pressure piping need not be reached, by pressure piping and low pressure pipeline individual cast, can reduces cost by a relatively large margin.
3rd, the setting of body base outside screw, can be threadedly coupled, group with the gas cylinder equipped with gases at high pressure
Dress is convenient, and increases air-tightness and stability.
4th, flowmeter can conveniently detect the size of flow in escaping pipe, targetedly using flow control valve to flow
Size is adjusted, and increases Consumer's Experience.
5th, the setting of mouth is filled, facilitates gases at high pressure to be filled with after being finished, recycle Portable oxygen cylinder, increased
Service life.
6th, pressure gauge can allow people the moment knows remaining oxygen amount in Portable oxygen cylinder when in use, can be according to purposes
With the preparation that needs carry out abundance.When oxygen is filled with, it is also possible to which intuitively display is filled with the amount of oxygen, prevent from being excessively filled with oxygen
The accident such as component damage or blast occurs caused by gas.
7th, gases at high pressure overcome the elastic force of spring that piston is promoted to spring side, when piston end is moved to pressure-regulating valve
At the connector of low pressure pipeline, a small amount of gases at high pressure flow to low pressure pipeline at the gap by piston and low pressure pipeline, flow into
The gas of low pressure pipeline is less, therefore pressure is with regard to step-down.
8th, pressure piping due to the pressure of tube wall it is larger, being arranged on the middle part of valve body can allow valve body to bear the ability of pressure
It is bigger, increase the stability of valve body.
9th, the precision of needle valve adjustment is higher, can accurately adjust the air-flow size for flowing into escaping pipe.
