Description
Technical field
The utility model relates to oxygen generation system purity technical fields more particularly to one kind, and medical oxygen generator to be avoided to generate low pressure
The device of unpure oxygen.
Background technique
With the improvement of medical procedure, medical oxygen generator has gradually been promoted the use of at home, it overcome bottle oxugen and
The shortcomings that liquid oxygen and hidden danger.An important component in hospital center's oxygen supply engineering, excellent peace are had become at present
Quan Xing, reliability, economy are approved by hospital.
The oxygen generating port of used medical molecular sieve oxygen generation system currently on the market, oxygenerator is direct by a ball valve
It is connected to oxygen tank.The shortcomings that this structure, is:
1. after each oxygenerator deactivates a period of time, or in super flow oxygen, oxygen pressure tank can be reduced；Work as oxygen tank
Pressure reduction to a certain extent when, oxygenerator preparation impure (less than the 90%) oxygen of low pressure can enter oxygen tank in, cause oxygen
Oxygen purity in gas tank is inadequate, needs to debug unpure oxygen in discharge oxygen tank, can be only achieved 90% after 2~3 hours；
2. when air pressure tank is inadequate, impure (less than the 90%) oxygen of the low pressure that oxygenerator can generate, in oxygen tank pressure
Enter oxygen tank when power is low；It causes the oxygen purity in oxygen tank inadequate, needs to debug unpure oxygen in discharge oxygen tank, 2~3 is small
When after can be only achieved 90%；
3. since super flow causes oxygen tank oxygen few, and then when causing oxygen pressure tank inadequate, oxygenerator generates low
It presses impure (less than 90%) oxygen equally to can enter oxygen tank, causes the oxygen purity in oxygen tank inadequate, need to debug discharge
Unpure oxygen in oxygen tank can be only achieved 90% after 2~3 hours；
Thus applicant carried out beneficial exploration and trial, result of the above problems is had found, will be detailed below being situated between
The scheme to continue is generated under this background.
Utility model content
The technical problem to be solved by the utility model is to provide one kind with defect in view of the deficiencies of the prior art and keep away
Exempt from the device that medical oxygen generator generates low pressure unpure oxygen.
The technical issues of the utility model is solved can be realized using following technical scheme:
A kind of device for avoiding medical oxygen generator from generating low pressure unpure oxygen a, comprising: air tank, a pressure reducing valve, an oxygen processed
The air of host, an oxygen tank, a tracheal system, the air tank storage enters oxygen main frame processed by pressure reducing valve, and feature exists
In further including a counterbalance valve, the oxygen main frame processed oxygen generating port is connect by the counterbalance valve with the oxygen tank.
In a preferred embodiment of the utility model, the oxygen main frame processed include a pair of of intake valve, a pair of of exhaust valve,
One balanced valve, a pair of of silencer, a pair of of adsorption tower, the compressed air that the air tank comes by the pressure reducing valve and it is a pair of into
It respectively enters after air valve in a pair of of adsorption tower, is handled by the adsorption tower, the nitrogen after absorption is discharged by exhaust valve, every
Equipped with a silencer for reducing exhaust noise behind one exhaust valve；The oxygen exhaust of the balanced valve and a pair of of adsorption tower connects
Connect, the oxygen after being balanced by balanced valve by the oxygen main frame processed oxygen generating port output.
In a preferred embodiment of the utility model, the back-pressure of the counterbalance valve is about 400KPa.
Due to using technical solution as above, it is lower than the utility model has the beneficial effects that: oxygenerator produces oxygen pressure
When back pressure threshold values, produced Low Pressure Oxygen not can enter oxygen tank, and easy to operate, effect is obvious, can be shortened and starts to from oxygen generation system
The time of oxygen supply, can also limit oxygenerator oxygen supply pressure, reduce or prevent impure Low Pressure Oxygen enter oxygen tank so that enter doctor
Pipe network is treated, accident rate is finally reduced, improves safety coefficient.
