Embodiment
With reference to figure 1, Fig. 1 illustrates according to distribution valve of gas bottle 1 of the present invention.Illustrated certain embodiments is designed to distribute the therapy breathing gas, and for example oxygen maybe can comprise the gaseous mixture of the oxygen that has helium, nitrogen, carbon dioxide, nitrogen oxide, nitric oxide etc.In other words, such certain embodiments is not thought of as restrictive, make the present invention be equal to applicable to requiring to use pressurized gas bottle and with other gas dispensing applications of the flow velocity distribution of gas of the pressure regulated and adjusting.
Distribution valve of gas bottle 1 provides main body 10, and main body 10 comprises top section 12, and top section 12 has gas outlet 14 to discharge gas to be allocated.As illustrated, gas outlet 14 has the form that is designed to the joint shape counterpart that connects with the flexible pipe that is used to distribute the oxygen that is used for the treatment of purposes.Main body 10 also provides bottom 16, and bottom 16 is configured to partly connect by screw thread 17 with the not shown head of opening of pressurized gas bottle.
In addition referring to figs. 2 and 3, by internal flow path, internal flow path has the internal path in main body 12 that will be described in more detail below from the pressurized gas of gas bottle.Pressurized gas enters such internal flow path by the gas access of the form of the inlet opening 18 in the bottom 16 with main body of being provided at 10, and is discharged from by gas outlet 14 after adjusting.The pressure that provides pressure gauge 19 to measure pressurized gas determining whether recharging pressurized gas bottle, and also confirms when pressurized gas bottle is filled into capacity recharging operation period.In this regard, provide and recharged mouthfuls 20 to allow gas bottle to be recharged with the distribution valve of gas bottle 1 that is attached on it.In the reality, though not shown, recharging mouth 20 can cover with dust cover.Conventional high pressure explosion counterpart 22 is provided.Explosion counterpart 22 is designed to break and keep being attached to the top section 12 of main body 10 because of the excess pressure in the gas bottle.For explosion counterpart 22, rated pressure is used in combination with the gas bottle with the stuffing pressure with about 2200psig between about 3025psig and about 3360pisg.
Pressurized gas flow into the separating valve of being appointed as reference number 96 below then, and then to being designed to that gas pressure is reduced to the level that is suitable for patient's use, for example are reduced to the pressure regulator 24 of 50psig.
The flow velocity of gas is by the flow control valve control that also will discuss in detail below, and flow control valve is adjusted by control knob 26.Flow velocity has been controlled in turning clockwise of control knob 26.Control knob 26 also is used for actuating separating valve by actuation mean, and in this case, actuation mean is the dentation protrusion 28 that suspends from control knob 26, and dentation protrusion 28 provides the leading edge 30 to tilt.When control knob 26 rotated in the counterclockwise direction, dentation protrusion 28 covered the slope shape part 38 of the cap linear element 48 of 40 depression in the leading edge 30 places contact of tilting.The cap linear element 48 of depression has covered the projection 101 of the valve stem part of separating valve 96, to activate separating valve 96 and cutoff high gas flowing in flow path.
Lid 40 is hinged to the top section 12 of main body 10 at its part 42 places relative with slope shape part 44, will cover the 40 vertical protrusions 44 that are connected to top section 12 pivotly.Briefly with reference to figure 9, but rod 45 allows so hinged connection and pivotal action.When separating valve 96 is activated and removes when activating, can pivot connect allow cover 40 mobile.This covers 40 and provides groove 46 in this respect, makes that covering 40 skips gas outlet 14 during operation is moved.Therefore cover 40 top sections 12 that covered main body 10 to be easy to activate separating valve 96 and to prevent that by the cap shape part 48 of using depression fume etc. from entering separating valve 96.Though not really preferred, the flexible protective cover that has covered the projection 101 of separating valve 96 can be used as and covers 40 substitute and use.Even more not preferably, lid 40 can be cancelled to allow directly to activate separating valve 40 by dentation protrusion 28.
Pilot outlet 50 is provided, has made distribution valve of gas bottle 1 can be used for for example being connected to the secondary purpose of ventilation equipment.In addition, provide low pressure relief valve 49, if release pressure when having the back pressure of unacceptable degree inadvertently with distribution valve of gas bottle 1.
Control knob 26 provides skirt section 27, and skirt section 27 has " OFF " position that mark indicates separating valve to close, demarcates flow velocity and aided location (" AUX "), when aided location is used in hope during from pilot outlet 50 distribution of gas.The rotation of control knob 26 preferably stops at the peak flow rate (PFR) place by sheet 54 guiding, and sheet 54 suspends and contacts the protrusion 56 that is attached to protrusion 44 from control knob 26.Specific flow velocity or function " OFF " or " AUX " are selected when relative with gas outlet 14.
Distribution valve of gas bottle 1 is routinely by the forging brass manufacturing.Control knob 26 and lid 40 can be by the impact resistant plastics manufacturings.
With reference to figure 4, pressurized gas enters distribution valve of gas bottle 1 by gas access 18, and gas access 18 is openings of internal flow path, and it is limited in first access 60 of such internal flow path.First access 60 can comprise known porous particulate filter 62, and it is formed by sinterred brass and keeps putting in place by screw-thread fit part 64.
Recharging path 66 is communicated with at first access 60 with between recharging mouthfuls 20.Recharge mouthfuls 20 provide be positioned at recharge mouthfuls 20 amplification recharge path 68.The known valve assembly 70 that recharges is positioned at and recharges path 68, recharges valve assembly 70 and is shown in an open position for illustrated purpose is depicted as.Recharge valve assembly 70 and provide inlet counterpart 72, the filter 74 that inlet counterpart 72 has access 73 and formed by sinterred brass.In addition, removable valve element 76 is biased to open position by spring 78.When recharging bottle, known coupling is attached to and recharges mouthful and gas pressure pushes its illustrated open position with valve element 76.Pressure in the gas bottle maintains normal closed position with removable valve element 76.
Pressure gauge 19 also is communicated with by instrument path 80 with first access 60, makes pressure gauge 19 be exposed to the gas pressure in the gas bottle.
With reference to figure 5 and Fig. 8, first access 60 leads in second access 82 and the 3rd access 84, and second access 82 and the 3rd access 84 are respectively in end 86 and 88 places terminate in two peripheral openings 90 and 92 of isolating valve opening 94.
Separating valve 96 is positioned at the bar-shaped structure of isolating valve opening 94 and having prolongation.Separating valve 96 provides valve stem part 98 and valve portion 100.Valve portion 100 is formed by the constriction of separating valve 96, has allowed flow passage when separating valve 96 is shown in an open position, and two O type circle Sealings 102 and 110 provide the sealing of isolating in the valve opening 94.O type circle Sealing 102 and 104 prevents when separating valve 96 is pressed downwardly onto closed position by the top section 12 outstanding projections 101 from main body 10 of valve stem part 98 from isolating the gas flow of valve opening 94.Because O type circle Sealing 102 and 104 directly is exposed to pressurized gas, so gas pressure helps Sealing is pushed against on the isolation valve opening 94 to help sealing.O type circle Sealing 102 and 104 is formed by elastomer compounds, is for example formed by known fluorocarbon.
Separating valve 96 is biased in open position by spring 106, and the shoulder 108 of separating valve 96 and those bottoms in the step 107 of isolating valve opening 94 in spring 106 breastings.As obvious, therefore separating valve 96 and is remained on by lid 40 and isolates in the valve opening 94 in protrusion 101 places are placed in the cap linear element 48 that covers 40 depression.
As illustrated, isolating valve opening 94 opens in relative end.Like this, preferably provide wiper by O type circle Sealing 109 and 111.Other O type circle pressure seal is provided by O type circle 110.
With reference to figure 7 and Fig. 8, Fig. 7 illustrates the separating valve 96 at open position.Pressurized gas flow through second access 82, by peripheral openings 90 and enter into and isolate in the valve opening 94.The open region that is provided by constriction 100 allows gas stream to cross peripheral openings 92 and flow out the 3rd access 84 then.It should be noted that peripheral openings 90 and 92 has more long-pending than second access 82 and the 3rd access 84 little a lot lateral cross section, with the power that prevents pressurized gas separating valve 96 is compressed in and isolates in the valve opening 94.On the other hand, for example can use other valve designs to substitute constriction, the path that has connected that the club shaped structure of separating valve 96 can provide, the via design that has connected for when separating valve 96 is activated into its open position and peripheral openings 90 and 92 pairs directly.Yet this is with the accuracy to a certain degree that requires to be in operation and therefore more complicated for such embodiment.
When 40 slope shape part 38 cover in leading edge 30 contact that rotates to " OFF " position and dentation protrusion 28 when control knob 26, lid 40 was pushed down, from and promotion separating valve 96 to Fig. 8 illustrated closed position.At this point, peripheral openings 90 and therefore second access 82 between O type circle 102 and 104, isolated, flow to the 3rd access 84 to prevent pressurized gas from second access 82.Control knob 26 makes the dentation protrusion 28 that suspends separate from slope shape part 38 from " OFF " position in the rotation of relative direction, turns back to open position to allow separating valve 96.
As illustrated, separating valve 96 is orientated and makes that separating valve 96 can be by the cam-like motion action of dentation protrusion 28 when Spin Control button 26.This provides the compact layout that is used for distribution valve of gas bottle 1.Though not really preferred, separating valve 96 can be transverse to the axis orientation of main body 10, or directed on the direction of control knob 26.In this case, dentation protrusion 28 or other contact members will head-on contact projection 101 to activate separating valve 96.
Another point relates to the biasing of separating valve 96, and separating valve 96 is biased to open position.Any separating valve of can setovering is in the closed position.By with constriction 100 and two O type circle Sealings 102 and 104 positions of reversing simply, make that O type circle Sealing 102 and 104 is isolated peripheral openings 90 when static, this easily finishes with separating valve 96.Yet in such a case, dentation protrusion 28 must be by displacement and 27 extensions around the skirt section, to activate separating valve 96 to its open position.That yes is not really preferred for this, because this will increase operation control knob 26 desired power.
Refer again to Fig. 6, the 3rd access 84 is in the pressure regulator 24 places termination that is used to reduce pressure.Pressure regulator 24 has conventional design.Pressurized gas enter by O type circle Sealing 114 and are sealed in valve seat part 112 in second inlet channel 88.Valve seat part 112 preferably provides not shown filter, to be used for filtered particulate matter.The piston 124 that the inner room 116 that is provided by dome 118 is had periphery O type circle Sealing 126 is divided into high pressure side 120 and low voltage side 122.Dome 118 is kept putting in place by retention nut 127.The valve 128 that integrally forms with piston 124 provides the axial passage (not shown), and this axial passage is communicated with between high pressure side 120 and low voltage side 122.Such passage provides mouthfuls 130,120 passes through axial passage from low voltage side 122 to the high pressure side with the high-pressure gas flow that allows incoming flow.If pressure is lower than pressure set-point, then incoming flow gas driven piston 124 is provided by the biasing that is provided by spring 132, thereby valve 128 is pushed to open position.
If pressure increases, the biasing actuating valve 128 that the pressure opposing of 120 opposing pistons 124 is provided by spring 134 in the high pressure side is to valve base element 112, is driven against valve seat part 112 until the fibrous tip part 136 of valve 128, thereby sealed its inner passage.At this point, do not work against pressure regulator 24 because there is superheated steam, so valve 128 is removed to set up gas stream again from valve base element 112.As skilled in the art to understand, aforementioned operating in together may be vibrated under the pressure.
Pressure regulator 24 can be described as the internal flow path that will be used for gas and is divided into high pressure side and low voltage side.Below discussed the high pressure side.As for low voltage side, adjusted gas flow in first exit passageway 138 and in the chamber 140 of flow path.Refer again to Fig. 4, low pressure relief valve 49 is communicated with chamber 140.Low pressure relief valve 49 is conventional relief valves and comprises the valve 50 that is biased to closed position by spring 51.In addition with reference to figure 9, the 3rd exit passageway 146 that gas flows through first exit passageway 142, second exit passageway 144 and is communicated with gas outlet 14 in the mode that will discuss.Gas outlet 14 can provide filter 148, is back in the distribution valve of gas bottle 1 to prevent material.Safety check also can use, and its advantage is the backflow that such equipment has prevented liquid.
Chamber 140 has held the flow control valve with plate-like orifice plates 152 forms, and plate-like orifice plates 152 has the periphery aperture of demarcating for specific flow velocity.The aperture of such demarcation is by reference number 154 diagrams.The top in chamber 140 has load-bearing surface 156, and plate-like orifice plates 152 is placed along it.Plate-like orifice plates 152 is connected to control knob 26 by Control Shaft 158.It is illustrated when on its skirt section 27, being marked with the certain location of flow velocity in control knob 26 rotates to as Fig. 1 and Fig. 2, specific corresponding aperture, for example aperture 154 is aimed at first exit passageway 142, to select and therefore to measure the specific demarcation flow velocity of gas to gas outlet 14.Sealing is provided by the rounded seal 160 that is placed in the load-bearing surface 156.
For the purpose of constructing compactness, Control Shaft 158 provides constriction 161, and constriction 161 allows gas stream from second exit passageway, 144 to the 3rd exit passageways 146.O type circle Sealing 162 and 163 prevents control axis hole 164 effusions of gas from having comprised Control Shaft 158.
Plate-like orifice plates 152 provides no orifice area.Control knob 26 can be manipulated in Fig. 1 the such position that is called as " AUX ".In diagram, this position is in the leftmost side in the skirt section 27 of control knob 26.In such position, gas can not eluting gas outlet 14.Its objective is and allow gas to distribute from the pilot outlet 50 that is connected to chamber 140 by transmission path 170.Can use the different flow restriction by pilot outlet 50, for example gas is in the situation of helium oxygen mixture or nitric oxide mixture but not oxygen therein.
Possible alternate embodiment for the flow control valve that uses plate-like orifice plates 152 is the flow control valve with known vertical effect, and this control valve drives by screwed Control Shaft 158 is provided, to produce the motion that requires.
Pilot outlet 50 provides the valve 172 that is driven into closed position usually by gas pressure.Sealing is realized by O type circle Sealing 174 at valve 172 places.Valve 172 also is biased to closed position by spring 176.She Ji the gas coupling with known can engage pilot outlet 50 by protrusion especially, to engage valve 172 and therefore valve 172 to be shifted onto open position and overflowed to allow adjusted gas.
With reference to Figure 10, control knob 26 is connected to Control Shaft 156 by the maintenance bolt 180 that is positioned at its depression 182.Depression 182 is covered by lid 184.Circle 186 is attached to Control Shaft 156, circle 186 ratchet or the indentures 188 that provide corresponding to the position of Control Shaft 156, and the function of wherein specific demarcation aperture and for example " OFF " and " AUX " is aimed at second exit passageway 142.Can engage indenture so that but control knob 26 is kept putting in place with delivery mode by one or more spring-loaded elements that form by the bearing 190 of spring 192 biasings.
Another relates to the formation of dentation protrusion 28 to the possible modification of distribution valve of gas bottle 1 again.Not really preferred embodiment is dentation protrusion 28 to be attached to arm that is connected to Control Shaft 158 etc.What further substitute is for separating valve 96 provides contact member, as the cam that forms in the lower surface of control knob 26.All requirements be employed specific contact member must be relevant with control knob 26 with control knob 26 rotations.In other words, aforementioned substituting is not preferred, because they do not cause the design for the compactness of illustrated distribution valve of gas bottle.
Yet, provide the alternate embodiment of the distribution valve of gas bottle 1 that separating valve actuates shown in Figure 1B, Fig. 2 B, Fig. 7 B, Fig. 8 B and Figure 11 in different slightly but preferred mode.Thereby alternate embodiment is by having eliminated for the structure of having simplified distribution valve of gas bottle 1 with reference to the needs of dentation protrusion 28 described in the preamble of figure 1, Fig. 2 and Fig. 6, slope shape part 38, lid 40, part 42, groove 46, cap linear element 48, sheet 54, protrusion 56, spring 106 and relevant part.The alternate embodiment of Figure 1B and Fig. 2 B has been used circle 200, has track 202, separating valve guiding element 204 and containment vessel 206.Circle 200 and track 202 illustrate in greater detail in Figure 11, and Figure 11 shows circle 200 and comprises head part 208 and rail portion 210.Rail portion 210 further comprises the lower railway part 212 of depression, the incline section 214 of depression, the part 216 that gets on the right track, lower railway end 218 and the end 220 of getting on the right track of depression.In Figure 11 also as seen in downward mode from enclosing the outstanding rotation retainer 222 of 200 rail portion 210.
The track 202 of circle 200 is suitable for receiving separating valve guiding element 204 or of this sort active element.When separating valve 96 was in the closed position, separating valve guiding element 204 occupy in the lower railway part 212.When control knob 26 rotated in the clockwise direction, separating valve guiding element 204 moved to the part 216 that gets on the right track along incline section 214, and separating valve 96 is shown in an open position herein.When separating valve guiding element 204 moves to getting on the right track during part 216 of circle 200 from lower railway part 212 by incline section 214, isolate valve stem part 98 and be pulled, thereby actuated separating valve 96 to its open position (part Fig. 7 B) in the orientation that makes progress.Similarly, when control knob 26 rotates with counter clockwise direction, separating valve guiding element 204 moves along upper rail part 216, through incline section 214 down to lower railway part 212, isolate valve stem part 98 herein and be pulled, thereby actuated separating valve 96 to its closed position (see figure 8) in downward orientation.When separating valve guiding element 204 arrives when getting on the right track end 220, the rotation of control knob 26 is preferably stopped under the peak flow rate (PFR) by rotation retainer 222, and rotation retainer 222 contact corresponding structure are further rotated preventing.
Forward Fig. 7 B and Fig. 8 B now to, Fig. 7 B illustrates the alternate embodiment of the separating valve 96 that is shown in an open position.The embodiment of Miao Shuing as described above, pressurized gas flow through second access 82, by peripheral openings 90 and to isolating in the valve opening 94.The district that opens that is provided by constriction 100 allows gas stream to cross peripheral openings 92 and flow out the 3rd access 84 then.The cross-section area that it should be noted that peripheral openings 90 and 92 to the second accesies 82 and the 3rd access 84 is much smaller, with the power that prevents pressurized gas separating valve 96 is compressed in and isolates in the valve opening 94.
Fig. 8 B illustrates the alternate embodiment of separating valve in the closed position 96.When control knob 26 rotates to " OFF " position and separating valve guiding element 204 when being pulled to the lower railway part 212 of circle 200, separating valve 96 is pulled to closed position.In closed position, peripheral openings 90 and therefore second access 82 between O type circle 102 and 104, isolate, flow to the 3rd access 84 to prevent pressurized gas from second access 82.Control knob 26 causes the positive displacement of separating valve guiding element 204 along track 202 from " OFF " position in the rotation of opposite direction, so that separating valve 96 is moved back to open position at axial direction.
Except that the operation of separating valve 96, the operation of the every other aspect of the illustrated alternate embodiment of distribution valve of gas bottle 1 is identical or identical substantially with above description in conjunction with first embodiment and Fig. 1 to Fig. 6, Fig. 9 and Figure 10.Therefore be not repeated in this description at this.
