Definitions
- the present invention relates to a device for storing and mixing two gases or two mixtures of gases under pressure.
- An object of the present invention is therefore to provide a device which allows the storage and mixing of two gases or two gas mixtures allowing in situ the preparation of the final mixture with an accuracy of the content of the different components at least as good than in the prior techniques and allowing very low levels of some of the gases, of the order of a fraction of ppm or a few ppb.
- the device for storing and mixing two gases or a mixture of gases under pressure comprises:
- a body tightly fixed in the opening of the external enclosure a first passage (20 ') having an internal end (20'a) connected to the opening of the internal enclosure (18) and an external end (20'b) and being fitted between its two ends with sealing means controllable (1 ') and a filling channel (3'),
- a second passage (20) having an internal end (20a) opening into the external enclosure (15) and an external end (20b) and being equipped with controllable closure means (1) and a filling channel (3 ) - two outlet channels (21, 21 ') each connected to an external end (20b, 20'b) of each passage (20, 20') of the tap (19), each having an internal end (21a, 21'a ) and an external end (21b, 21 'b), and successively comprising:
- first and second pressure adjustment means (6, 6 ') at least one controllable flow selection barrel (7, 7 ') connected to one of the pressure adjustment means (6, 6'), the barrel (7, 7 ") allowing the selection of orifices of different sizes ( 9, 9 ') for the exit channel (21, 21') equipped with the barrel,
- This device is primarily constituted by a pressure resistant outer cylinder “15 for holding the gas or gas mixture diluent.
- the bottle 15 has an upper opening 16 in which a double-way valve 19 is engaged, the body of which is tightly fixed in the opening 16.
- the double-way valve 19 essentially has two passages 20 and 20 ′, one of which has a first end 20a, 20'a opens into the underside of the body of the double-way valve and the second end of which 20b, 20'b opens into the upper part of the body of the double-way valve.
- Each passage 20, 20 ′ comprises closure means 1, 1 ′ of said passages.
- These obturation means 1, the are controllable. They generally consist of high pressure valves.
- Each passage 20 and 20 ' also includes a filling path 3, 3' pierced through the valve body: a first end of each filling path 3 or 3 'opens into a passage 20 or 20' and the other end at outside the valve body 19.
- This last outer end can lead to a filling connection 2, 2 ′ for connection to a gas source.
- This filling channel makes it possible to fill the enclosures without dismantling the double-way valve 19.
- a non-return valve 4, 4 ' can be placed on each filling channel 3 and 3' of the valve 19, more precisely between the filling connector. and the filling route.
- the non-return valves 4, 4 ′ can be blocked to allow the chambers to be purged.
- the filling connection 2, 2 ' is provided with a polarizing key so as not to confuse the inputs of the two enclosures and possibly to avoid that the user can fill the enclosures himself.
- an internal pressure resistance bottle 17 Inside the external enclosure 15 is mounted an internal pressure resistance bottle 17, the opening 18 of which is connected to the end 20 ′ a of the first passage of the double-track tap generally by a pipe.
- each passage 20 of the tap 19 is each connected to an outlet channel 21, 21 '.
- These outlet channels include pressure adjustment means 6, 6 ′ which are generally double stage regulators. It goes without saying that other types of regulators could be used.
- These pressure adjusting means 6 and 6 ' are adjusted to provide an outlet pressure which is preferably identical for the two gases.
- a residual pressure valve 51, 51 ', and possibly a non-return valve 52, 52' can also be placed between the external end 20b, 20'b of each passage 20, 20 'of the tap 19 and the internal end 21 a, 21 'a from each exit channel 21, 21'.
- valves are then placed between the shutter means 1, 1 'of the enclosures and the pressure adjustment means 6, 6', and downstream of the filling paths of the enclosures 3, 3 '.
- the residual pressure valves make it possible not to empty the chambers completely when the device is used: in fact, these valves allow the passage of gas only above a certain predetermined pressure.
- Each of these residual pressure valves 51, 51 ' can also be lined with a non-return valve 52, 52' which prevents the gas from returning to the enclosure after having passed through one of the pressure adjusting means 6, 6 '.
- This implementation makes it possible to prevent an impurity entering the enclosure once the gas from the enclosure has been delivered. This also avoids having to fill the speakers with a series of compressions and purges each time they are refilled.
- the device also comprises on at least one of the outlet channels 21, 21 ', preferably on both, and downstream of the pressure adjustment means 6, 6' a flow selection barrel 7, 7 ", allowing the selection orifices of different sizes 9, 9 'for the outlet channel (s) 21, 21' equipped with the barrel.
- the selection of the orifices can be done by any type of manual control means 8, 8 '
- These barrels allow the selection of the diameter of the gas outlet orifice leaving the enclosures and therefore of the gas flow rates circulating at the external end 21 b, 21 ′ b of the outlet channels 21, 21 ′. 7 'are oriented so as to place the orifices 9 and 9' opposite the end of the pressure adjustment means 6 and 6 '.
- these barrels include three positions: a closed position which does not allow gas to flow and, for example, two positions in a flow ratio of half.
- a closed position which does not allow gas to flow
- two positions in a flow ratio of half are positions: a closed position which does not allow gas to flow and, for example, two positions in a flow ratio of half.
- These barrels with three positions make it possible to create the flow of a single gas, in particular the diluent gas of the external enclosure which then flows at the outlet of the device; this position allows, for example, to have a zero reference when calibrating an analysis device.
- barrels also make it possible to have at the outer end of the outlet channels 21 and 21 'two concentrations of gas, for example, of a double ratio and to be able to calibrate a measuring device by making a full calibration point scale and another point at half the full scale.
- This type of barrel can in particular correspond to that described in application WO 96/07843.
- the orifices 9, 9 'of the barrels 7, 7' are equipped with a low pressure particle filter.
- the device according to the invention can comprise a high pressure particulate filter 12, 12 'placed at the external end 20b, 20'b of each passage 20, 20' of the tap 19.
- the device can include high pressure manometers 13, 13 'placed on each outlet channel 21, 21' upstream of the pressure control means 6, 6 '. It may also include low pressure manometers 14, 14 'placed after each pressure control means 6, 6'.
- the high pressure manometers 13, 13 'placed before the pressure control means 6, 6' make it possible to read the pressure in each of the chambers and the low pressure manometers 14, 14 'placed after the pressure control means 6, 6' allow the user of the device to adjust said pressure control means 6, 6 'to the desired outlet pressure.
- the external ends of the outlet channels 21, 21 ′ are connected to a mixing chamber 10, the outlet of which is itself connected to a single outlet terminated by an outlet valve 11.
- This chamber preferably has a particular geometry which allows to mix the two gases or gas mixtures coming from each of the conduits in order to homogenize the mixture during its circulation in this space.
- the mixture of gases to be diluted can already be diluted in acceptable proportions, for example of the order of a few ppm, in the internal enclosure while the external enclosure contains the diluent gas. Given the dilution rate of the active gases in the internal enclosure, this can initially be prepared easily and precisely and its storage does not raise any particular problems.
- the gas mixtures or the gases contained in the two enclosures are at the same pressure and the ratio of the volumes of the two enclosures is equal to the ratio of the quantities of gases or mixtures of gases to be sampled in the two enclosures to obtain the mixture final. It should also be noted that, after the internal enclosure and the two-way valve have been placed inside the external enclosure, the two enclosures can be conditioned and filled easily using the double track.
- the internal enclosure has a volume of the order of 1/100 the volume of the external enclosure, so that the dilution rate corresponding to the average calibrated orifice on each of the two outlet channels implies that the two speakers empty at the same speed.
- the two residual pressure valves can either be connected to an alarm indicating to the user that one of the chambers is empty, or connected together so that the closure of one of them causes the closure of the second and This prevents any withdrawal of one of the two speakers when only one is emptied.
- the relative dimensions of the two enclosures are not, however, fixed at this ratio, it is the ratio of their volumes which causes the average rate of dilution of the gas.
- the internal enclosure 17 fixed to the double-way valve 19 is placed inside the external enclosure 15 and the body of the double-way valve is fixed in leaktight manner in the opening 16 of the external enclosure.
- the passages 20 and 20 ′ the initial enclosure and the internal enclosure 17 and the external enclosure 15 are conditioned and filled.
- the sealing means 1 and 1 ′ ensure the closure of these two enclosures.
- the gases or mixtures of gases contained in the chambers 15 and 17 can be stored for the desired time.
- the internal enclosure 17 should preferably have transverse dimensions smaller than the section of the opening 16 of the external enclosure 15 in order to allow it to be placed inside the pregnant 15 ..
- the use of the device according to the invention is particularly suitable for the preparation of a mixture of CO and air from a mixture of CO and N 2 stored in the internal enclosure and of a mixture of air and O 2 stored in the external enclosure.
- CO can have a concentration between 1 and 10,000 ppm in N 2 .
