Fig. 1 is structural representation of the present utility model；
Fig. 2 is the concrete structure schematic diagram of a kind of depurator that this utility model is used；
Fig. 3 is that the A-A of Fig. 2 is to sectional view.
Detailed description of the invention
Seeing Fig. 1, the gas cylinder with built in purifier of the present utility model includes bottle 18 and cylinder valve 19, and internally installed at gas cylinder has independent depurator 20, and this depurator 20 is provided with air inlet, and the escape pipe of this depurator 20 is connected with cylinder valve 19.
Fig. 2 is the structural representation of a kind of depurator 19 that this utility model is used, including gas filtration chamber 1, multiple air inlet 2, escape pipe 3 and the valve control system 4 controlling gas flow.It is provided with filtration channel 5 and gas distribution channel 6 in gas filtration chamber 1, in filtration channel 5, is filled with gettering material.Valve control system 4 is arranged on the top in gas filtration chamber 1, air inlet 2 and escape pipe 3 and is arranged on valve control system 4.In the present embodiment, gas distribution channel 6 uses circular pipe, circular pipe is arranged on the center in gas filtration chamber 1, the bottom of circular pipe is connected with the inwall in gas filtration chamber 1 by annular plate 7 with holes that (gas filtration chamber 1 is tubular structure, bottom is downwardly protrude to form cushion chamber), between the inwall in circular pipe and gas filtration chamber 1, form filtration channel 5.
Valve control system 4 includes lower cover 8 and upper cover body 9, lower cover 8 covers the open-mouth being arranged on filter cavity 1, multiple air inlets 2 tilt the sidewall being arranged on lower cover 8 of (downwards), being further opened with multiple vertical through hole 10 on lower cover 8, multiple vertical through holes 10 are positioned at the top of filtration channel 5.Upper cover body 9 is arranged on above lower cover 8, and forms cavity above the position of multiple Vertical Channel 10, is mounted on spring valve 11 in cavity, and air inlet 2 leads to the bottom margin of spring valve 11；It is also formed with another cavity in center between upper cover body 9 and lower cover 8, in this another cavity, spring valve 12 is also installed, being provided with one or more air feed interface pipeline 13 in the lower sidewall position of spring valve 12, these one or more air feed interface pipelines 13 are connected with gas distribution channel 6 by the one or more confession vent holes 14 being opened on lower cover 8.Escape pipe 3 then run through upper cover body 9 and stretch between aforesaid upper cover body 9 and lower cover 8 center formed cavity in.In the preferred structure of the present embodiment, lower cover 8 forms bulge-structure above gas distribution channel 6, constitutes gas buffer cavity 15.The bottle of the 1st embodiment is suitably mounted to outside gas cylinder.The outside with described gas cylinder installed by described depurator, and the output channel of described gas cylinder is connected to the air inlet of described depurator, and escape pipe couples external connector via outlet side interface and is directly used in client terminal gas with pipeline.
Sidewall in upper cover body 9 is further opened with evacuation interface channel 16, and what sidewall at spring valve 12 was corresponding offers evacuation through hole 17, and evacuation interface channel 16 connects with evacuation through hole when spring valve 12 is closed.
Its depurator 20 of gas cylinder of the present utility model is arranged on the inside of gas cylinder 18, and escape pipe interface is connected with cylinder valve 19 bottom spiral shell button.
Operation principle during application is following (seeing the bottle inner structure schematic diagram of Fig. 2 and Fig. 3):
This depurator is controlled by spring valve 12,11 two pressure valve of spring valve.Under not having external force pressure condition, two valves are in the state of being automatically switched off, and under the conditions of being under pressure more than >=0.2MPa, two valves automatically turn on.
Spring valve 12 controls two interfaces, i.e. evacuation interface channel 16 and air feed interface pipeline 13.
After depurator installs in (steel) gas cylinder, the initially section of knot, need first gas cylinder internal air to be carried out evacuation pretreatment.Spring valve 12 now be in off position under (in controlled two interfaces: evacuation interface channel 16 is in opening, i.e. the through hole on evacuation interface channel 16 and spring valve 12 is in an ON state；Air feed interface pipeline 13 is closed, i.e. air feed interface pipeline 13 does not accesses the inside of spring valve 12), in bottle, air is connected with spring valve 12 by evacuation interface channel 16, extraneous evacuation, and air-flow carries out vacuum displacement via spring valve 12 output；Steel cylinder is carried out vacuum displacement process qualified after, close cylinder valve, depurator now can enable.
Entering pneumatic inflation and fill knot section, when pressure is more than >=0.2MPa, spring valve 12 and 11 liang of valves of spring valve automatically turn on.Spring valve 12 is in the on state (in controlled two interfaces: evacuation interface channel 16 is closed, air feed interface pipeline 13 is in opening), air-flow is entered gas pipeline by evacuation interface channel 16, is entered filter chamber via buffering cavity, enter in steel cylinder by spring valve 11 again, during until pressure reaches 15MPa, close cylinder valve；Spring valve 12 and 11 liang of valves of spring valve now are in opening all the time.
When gas output in bottle, air-flow enters filter chamber via spring valve 11, enters gas pipeline and air feed interface pipeline 13 by buffering cavity, spring valve 12 export.
When pressure of the inside of a bottle is less than≤0.2MPa, spring valve 12,11 liang of valves of spring valve are automatically switched off, and now to close cylinder valve in time, until steel cylinder is directly inflated by next time.
