Abstract
A kind of oxygen cylinder, including gas cylinder body, the seal assembly in gas cylinder body bottleneck seam；The seal assembly includes annular seal part, and annular seal part upper end horizontally outward extends to form step, and lip packing washer is enclosed on the step lower end of seal, and skeleton is on the inside of the cavity inner wall of seal lower end；The width of the lip packing washer horizontally outward extends the width to form step more than annular seal part upper end, and the height of lip packing washer is less than the height of annular seal part.The utility model good sealing effect, seal is opened by application specific architecture when using every time, gas cylinder is changed after having used.Gas cylinder does not use valve seal, but uses flanging process, good sealing effect, and long-time is not revealed or micro leakage.
Description
Technical field
It the utility model is related to a kind of oxygen cylinder used under medical instruments field, more particularly to emergency survival state.
Background technology
Oxygen is the existence necessity of the mankind, and the normal physiological metabolism of the mankind be unable to do without oxygen.Oxygen cylinder is to be used to aid in
The oxygen supply equipment of the various diseases caused by anoxic is treated, is mainly used in hospital, first-aid station, sanatorium, residential care, battlefield
Rescue, individual health care and various anaerobic environments.Stop valve for cylinder is installed on currently used oxygen cylinder, transport, load and unload with
And due to frequent controlled valve, the leakage of valve can be caused, it is necessary to fasten valve manually during use.After revealing for a long time,
If can not supplement in time, the gas flow in bottle just can not meet the use oxygen demand at emergent moment.
The content of the invention
The purpose of this utility model is to overcome the above-mentioned insufficient of prior art and provide a kind of oxygen cylinder, sealing effectiveness
Good, long-time is not revealed or micro leakage.
The technical solution of the utility model is：Including gas cylinder body, the seal assembly in gas cylinder body bottleneck seam；
The seal assembly includes annular seal part, and annular seal part upper end horizontally outward extends to form step, lip packing pad
Snare is mounted on the inside of the cavity inner wall of seal lower end in the step lower end of seal, skeleton；The width of the lip packing washer
Degree horizontally outward extends the width to form step more than annular seal part upper end, and the height of lip packing washer is less than annular
The height of seal.
The seal assembly is pressed in gas cylinder body by flanging process.
The sealing member material soft metal material, such as copper alloy, nickel alloy.
The lip packing washer material is nonmetallic materials such as silicon rubber, ethylene propylene diene rubber, polytetrafluoroethylene (PTFE) etc..
Described framework material is soft metal material, such as copper alloy, nickel alloy.
The beneficial effects of the utility model are：Seal is opened by application specific architecture when using every time, after having used
Change gas cylinder.Gas cylinder does not use valve seal, but uses flanging process, good sealing effect, does not reveal or micro lets out for a long time
Dew.
Brief description of the drawings
Fig. 1 is general structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of the utility model seal assembly.
Embodiment
In Fig. 1, a kind of oxygen cylinder, the gas cylinder body 4 formed is drawn by cold drawn steel plate and seal assembly forms.Gas cylinder body
4 volume is 0.12L, a diameter of 40mm, length 150mm.Seal 1 of the seal assembly by material for HPb59-1 ledrites
Formed with skeleton 3 and material for the seal washer 2 of EPDM.Seal washer 2 uses lipped configuration, installed in seal 1
Between gentle bottle body 4, prevent the gas overflowing in bottle from revealing.Skeleton 3 is arranged on inside seal, can prevent bottleneck flange
During seal be extruded, deform and influence the sealing effectiveness of seal washer, also can when by gas cylinder internal pressure,
It is in close contact with seal, plays a part of double-layer seal.Before gas cylinder assembling, first by seal 1, seal washer 2, the and of skeleton 3
Gas cylinder body 4 is put into special tooling, and special tooling can bear nominal 15MPa pressure.By 15MPa medical oxygen or aviation
Breathing is filled into special tooling with oxygen, and seal 1, seal washer 2, skeleton 3 are under the cooperation of special tooling, gentle bottle body
4 complete relative positioning, and then frock carries out flange to body, complete the sealing installation of bottle mouth of gas cylinder.Inflating gas cylinder assembling is completed
Afterwards, then to special tooling pressure release is carried out.Now, the inflation installment work of a gas cylinder is completed.Before use, gas cylinder is stored in packaging
In case, make-up gas etc. is not needed to safeguard in the lifetime of 1 year.During Emergency use, beaten using matched special valve
Gas cylinder is opened, is adjusted to need flow according to actual conditions, meets that breathing requires.After gas has used in bottle, gas cylinder is changed.
In Fig. 2, seal washer 2 is lipped configuration, pressure sealing to gas cylinder internal preferable, it is ensured that the oxygen in bottle
Not toward outward leakage.Skeleton 3 is on the inside of the cavity inner wall of the lower end of seal 1；Skeleton 3 can prevent from sealing in bottleneck turn-up process
Part 1 is extruded, and is deformed and is influenceed the sealing effectiveness of seal washer 2, also can be when by gas cylinder internal pressure, and seal
1 is in close contact, and plays a part of double-layer seal.
