The The invention will be explained in more detail with reference to the drawing. Show it:

1 a treatment station for pressure vessels for fire extinguishing and / or Feuerlöschübungs-purposes for refilling and refilling the pressure vessel with an extinguishing agent and a propellant such. B. compressed gas, wherein the pressure vessel is arranged on a base of the treatment station,

2 a base formation of the treatment station, in which the pressure vessel is pivotable under a Einklickbügel and thus fixable to the base,

3 a socket formation of the treatment station, in which the pressure vessel can be fixed by means of a securing bracket on the base,

4 a treatment station with several pedestals for pressure vessels,

5 a variant of the treatment station, in which the preparation of the filling quantity with extinguishing agent takes place in an interim container,

6 another variant of the treat station with interim container and

7 a variant of the treatment station with a mixing device for propellant and extinguishing agent before being pressed into the pressure vessel.

An in 1 illustrated treatment station 1 for refilling and refilling of pressure vessels F for fire extinguishing and / or fire fighting purposes has one at the treatment station 1 fixed base 2 to which a pressure vessel F can be placed for fire-extinguishing and / or fire-fighting purposes. The base 2 has an exchange valve 3 which can open and close in both directions of flow. However, it is also possible within the scope of a variant described later to limit the closing function to the transfer valve 4 in that sense that the replacement valve 3 is not executed closing. Pressure vessel F has a transfer valve 4 which can also open and close in both directions of flow. exchange valve 3 and transfer valve 4 are preferably designed as a quick-closing valve (s). When placing a pressure vessel F on the base 2 Both contact each other so that a common passage is formed. The base 2 is connected to a supply line 5 connected via a first node 8th to a central line 21 leads.

To the central line 21 a pressure-sensitive DS meter is connected. This pressure-responsive meter DS may be a pressure gauge, a pressure sensor, a functionally-responsive pressure switch, a pressure control valve, or a pressure relief device. The term "pressure-sensitive measuring instrument" or "pressure-measuring instrument" is to be understood as any functionally pressure-measuring or registering or limiting instrument.

The Extinguishing media can be an extinguishing agent for the use of fire or even for the practice use. Suitable blowing agents are, for example, halons and air.

To the central line 21 is in the first node 8th a propellant pressure line 6 connected. The central line 21 leads to a second node 8th , From him branch a drainage pipe 27 with a drain valve 25 from. Behind this is either a drain into the open or in a specially provided, not shown collecting container or optionally an extinguishing agent return line 9 with a device valve 56 , which opens only in the return direction. In the return line, a return pump PR may be provided.

In the propellant pressure line 6 is a compressor K or functionally equivalent propellant or compressed gas pump for sucking and pressing of z. As air or suitable gases such as halons arranged as a blowing agent.

If the following is a compressor K, then it is always a compressor functionally equivalent propellant or pressurized gas pumps to understand. It is also located in the propellant pressure line 6 a furniture valve 6a that is only in the direction of the central line 21 is open.

For the supply with extinguishing agent is an extinguishing agent tank T or other container or an extinguishing agent supply line 14 with an inlet valve 14a intended. The inlet valve 14a is connected to a mains connection. A switching valve acting as an extinguishing agent transfer point 11 ensures that the supply of extinguishing agent is either from the extinguishing agent tank T or from the extinguishing agent mains connection. The extinguishing agent is preferably liquid. If appropriate, a suitable foaming agent is added to it. From the changeover valve 11 leads an extinguisher line 12 to an extinguishing agent conveyor, such as an extinguishing pump P.

The extinguisher line 12 leads via a check valve 26 that is only towards the node 8th Passage granted to the second junction 8th , About the extinguishing agent supply line 14 For example, tap water to be used as extinguishing water can be externally supplied via the inlet valve 14a be supplied. The extinguishing agent supply line 14 is thus connected on the suction side to the extinguishing agent pump P. It is therefore possible, the feed of the extinguishing agent alternatively from the extinguishing agent tank T or the extinguishing agent supply line 14 make.

In or on the outside of the pressure vessel F, a filling height measuring instrument HS, for example a filling height sensor, can additionally be provided, which controls the filling level. The level meter HS can also be mounted on the base 2 be attached.

It must be ensured that one on the pedestal 2 attached pressure vessel F safe on the pedestal 2 sits and can not fly away or lift off at a valve opening. This is guaranteed by means of in the 2 and 3 shown one-click or circlips. The pressure vessel F is in 2 slanted on the pedestal 2 put on and in the direction of an arrow 16 swung to the vertical; as a variant, it is also possible to use the socket with the replacement valve 3 completely together with the aufzusetzenden pressure vessel under the fixed Einklickbügel to swing. In this case, the pressure vessel F passes under a clamping arm 17a of the click-in bar 17 and is thus secured upwards against taking off or flying away. In 3 the pressure vessel F is on the pedestal 2 placed. About the pressure vessel F is then in the direction of an arrow 18 a safety bar 19 with a safety arm 19a pivoted. Even so, the pressure vessel F is on the pedestal 2 secured against taking off or flying away. However, it is also possible to perform the backup valve of the pressure vessel on the base, the replacement valve and the transfer valve as the two parts of a locking / locking quick release coupling.

The functioning of the treatment station 1 to 1 is as follows: The treatment station 1 is located z. B. as a portable unit on a practice field. Of course it can also be a direct fire site. On the pedestal 2 a pressure vessel F to be refilled after use is put on. First of all, the starting point of the refilling must be clarified during placement, namely the question as to whether the pressure vessel F is really empty or whether it still has a residual charge. In the case of the residual filling, it must then be differentiated again whether there are still unknown residues of extinguishing and blowing agent in the pressure vessel F.

It is advantageous in terms of fast refilling, when in the course of emptying the pressure vessel F in use or for maintenance purposes by means of pressure and / or level measurements it is ensured that only the extinguishing agent, However, no or as little as possible release the propellant will, and that even before refilling the pressure vessel F the rest of the media remaining in it is determined.

This defined initial state before refilling can be such be achieved that by means of the pressure-measuring instrument or a pressure monitoring device DS in the delete or practice mode the level or the bypassing of the extinguishing agent is detected, so that no propellant is lost additionally. This sets Such a construction of the removal device of the pressure vessel F preceded by the fact that up to the end of the extinguishing agent in the pressure vessel F no blowing agent is lost from the same.

in the Interest in refilling as quickly as possible of the pressure vessel F can also on the dismissal of the Extinguishing agent from the pressure vessel F - if this is not required - be waived. This is through the use of an additional level meter HS for determining the extinguishing agent level in the pressure vessel F possible. Such a level meter HS can, for example, a filling level sensor or a level switch, in the or on the outside of the pressure vessel F may be appropriate.

For emptying the valves 3 and 4 to the supply line 5 open. Residual extinguishing agent flows in the case of complete emptying via the supply line 5 and the central line 21 through the drainage pipe 27 , the drain valve 25 and one in the disposal line 38 existing valve either into the open, or in the collection container, not shown, or is alternatively by means of an optional extinguishing agent recirculation pump PR on the extinguishing agent return line 9 in the extinguishing agent tank T or the extinguishing agent supply line 14 pumped back. Back pumping is useful so that the extinguishing agent return can work properly even with significant pressure in the extinguishing agent supply line from the tank or the extinguishing agent power supply. If the extinguishing agent is a chemical extinguishing liquid, ie not pure water, then it should in any case in the extinguishing agent tank T or in the extinguishing agent supply line 14 to be led back. A return to a specially provided, not shown collection container is possible.

Now the process of refilling or refilling begins. It is assumed that the treatment station 1 is equipped only with a low-power economic compressor K, which is not able to build up the full operating pressure in the container F.

By means of the compressor K is by the propellant pressure line 6 in the pressure vessel F as blowing agent air or other propellant introduced until the pressure gauge DS in the empty pressure vessel F, a desired pressure of 1.5 to 4, preferably about 3 bar is measured, for. B. for containers with a volume of about 10.7 liters. Then the propellant supply is interrupted. Now pumps the extinguishing agent pump P extinguishing agent, which corresponds to the position of the changeover valve 11 from the extinguishing agent tank T or the propellant supply line 14 comes from the extinguisher line 12 , continue to the central line 21 and the supply line 5 through the still open valves 3 and 4 in the pressure vessel F, until in this an overpressure of z. B. 10 to 20, preferably about 15 bar is reached. These pressures measures or limits the pressure measuring instrument formed, for example, as a pressure sensor DS. Thus, the filling process is completed and can be visually and / or acoustically signaled by the treatment station to the outside to the operator.

If a more powerful compressor K is available, the filling process can also take place in any order, eg. B. first the extinguishing agent and then with the compressor K blowing agent is pressed until the pressure of z. B. about 15 bar. Also, it can be supplemented with his help propellant in the pressure vessel, although, as described above, in the interest of rapid refilling before Befüllbeginn a significant amount Extinguishing agent in the pressure vessel F may be left.

When hurry exercise or fire use the refilling or refilling only a pressure vessel F is often not enough. There are too long practice or stoppages. The refill service takes too long. It is therefore advisable to supply several pressure vessels F in parallel to the replenishment. In 4 is an embodiment of a multiple treatment station 1a described. There are two fixed in the treatment station 1a installed sockets 2 provided parallel to each other, can be placed on the pressure vessel F. The number of pedestals 2 is arbitrarily expandable.

There are also pressure vessels F2 which, due to their size and / or weight, do not depend on the fixed base 2 the other pressure vessel F fit. Such pressure vessels are typically in practice very large stationary or mobile, for example, 50-liter extinguishers, which are on wheels. Because of their rather stationary or bulky character, it is not ergonomically or practically meaningful for them to be filled on pedestal of the treatment station 1a to put on or to dock there. For these pressure vessels F2 are the filling hoses 28 intended; they work parallel to the sockets 2 , Every filling hose 28 is therefore also with a replacement valve 3 provided on the transfer valve 4 of the pressure vessel F2 can be placed. The transfer valve 4 is preferably provided laterally in these pressure vessels F2 in the lower pressure tank area. The replacement valve 3 and the transfer valve 4 are preferably designed as the two parts of a latching, locking quick release coupling.

Also the number of filling hoses 28 is arbitrarily expandable. It is generally true that more sockets 2 and more filling hoses 28 without a change of concept are feasible. On the pedestal 2 with their replacement valves 3 are placed in the drawing pressure vessel F and by means of Einklick- or circlips after the 2 or 3 set. The replacement valve 3 and the transfer valve 4 can also be designed as the two sides of a locking / locking quick-release coupling, which can be dispensed with the securing bracket. This is not shown for clarity. The supply lines 5 the base 2 and the filling hoses 28 lead via nodes 40 and treatment valves 41 . 42 and 43 to a central line 21 , In this central line 21 there is the pressure gauge, the pressure sensor DS. Of course, for each base and / or filling hose of such a multiple treatment station, a separate pressure measuring instrument - not shown here - be provided. About a node 8th the central line 21 In addition, the propellant pressure line leads 6 in which the compressor K is located. Between compressor K and the node 8th is a valve 6a provided that only towards the node 8th opens. The compressor K is preferably after as in the treatment station 1 , a compressor K low power with the advantage described there. To the nodes 40 the supply lines 5 and the filling hose 28 are drainage pipes 22 connected, in which are drain valves 23 are located. The drainage pipes 22 are optionally combined to form an extinguishant return line 31 that have a valve 39 , only in the return direction to the extinguisher line 12 opens, to the extinguisher line 12 leads.

In You can get an extinguishing agent return pump PR, so that the extinguishing agent recycling even with significant pressure in the extinguishing agent supply line from the tank or from the extinguishing agent mains connection is working.

From the switching valve 11 leads the extinguisher line 12 over one only in the direction of the central line 21 open check valve 26 to the central office 21 , In the extinguisher line 12 there is the extinguishing agent pump P. On the forward side of the extinguishing agent pump P is a valve 12a and on the pressure side one only to the central line 21 opening valve 26 intended. From the extinguisher line 12 branches in front of the flow side of the extinguishing agent pump P and the valve 12a via the changeover valve 11 the extinguishing agent supply line 14 starting at the intake valve 14a located. With this inlet valve 14a is the extinguishant supply line 14 connectable to an extinguishing medium network.

It does not always make sense or can be structurally too complicated to return the extinguishing agent residues to the extinguishing agent tank T or the extinguishing agent network. This is especially true if, for example, tap water from the tap water network is used as the extinguishing agent or the discharged extinguishing agent is to be collected or disposed of separately. For these cases it is envisaged, inter alia, that instead of the extinguishing agent return line 31 a return line going into the open or into a collecting container (not shown) 37 downstream of the drain valves 23 branches off from these, in which - not shown - may be an extinguishing agent-return pump.

The treatment valves 41 . 42 and 43 in the supply lines 5 and the filling hose 28 also serve the extinguishing agent-return flow from the pressure vessels F and F2 to the central line 21 , From the central office 21 branches for this type of return a drain line 27 starting in which there is a drain valve 25 located. Downstream of this drain valve 25 leads from a node 54 an optional return line 9 via a likewise optional extinguishing agent return pump PR, so that the extinguishing Reverse flow even at significant pressure in the extinguishing agent supply line from the tank or from the extinguishing agent mains connection is working properly, the extinguishing agent line 12 , In addition, there is a valve downstream of the extinguishing agent return pump PR 56 that only towards the extinguisher line 12 opens. The return line 9 opens upstream of the valve 12a into the extinguisher line 12 ,

If the return lines 9 and 31 are not present, the extinguishing agent may alternatively from the node 54 via a disposal line 38 be disposed of into the open or in a collection container, not shown.

The multi-treatment station 1a to 4 works as follows: The treatment process starts here with one or more pressure vessels F on the pedestals 2 fitted and / or filling hoses 28 be attached to pressure vessel F2. The automatic of the treatment station 1a receives message about the placement and / or treatment ready locking of each pressure vessel F, F2 by means of a respective associated electrical or electronic message element, such as an end switch not shown or functionally equivalent acting proximity switch or a similar light barrier. This state of the connected or Eingedockt-Being a provisionally not ready to use treated pressure vessel can now be signaled to the outside at the respective pressure vessel z. B. by the lighting of a red LED 45 , The user manually activates a central power button to start the automatic treatment process 34 , Now, the automatic ensures preferably by the short opening of the drain valve 25 and additionally in the disposal line 38 existing, unspecified valve with connected disposal line 38 for atmospheric pressure at pressure gauge DS. Now, the automatic opens the arranged between each connected pressure vessel F and the pressure gauge DS treatment valve 41 . 42 . 43 to determine the pressure in the pressure vessels F, F2 and thus also information about its level and store. Between the pressure measuring operations on the individual pressure vessels F, F2 is preferably in each case the drain valve 25 in the drainage pipe 27 and additionally in the disposal line 38 existing valve, the connected with disposal line 38 At atmospheric pressure, briefly opened to reset the pressure on the pressure gauge DS. Now, the automatic is probably the most empty pressure vessels F, F2 known, and the filling or treatment of the pressure vessel F, F2 in the order of their determined level begins.

there it is assumed that the first pressure vessel F, F2 refilled as soon as possible should stand. First of all, therefore, preferably the most empty one Pressure vessel treated. For him will be his respective Treatment valve open.

For those on the pedestals 2 located pressure vessel F are the valves: 41 . 42 , and for the to the filling hose 28 connected container F2 it is the valve 43 , In addition, the respective container F, F2 associated drain valve 23 open. Likewise, the drain valve 25 opened and additionally in the disposal line 38 existing valve. In this way, the first pressure vessel Fx is emptied quickly and that until the pressure gauge DS measures or detects only atmospheric pressure in it.

It should be noted that it is also possible here not completely to empty the pressure vessel F, F2 before refilling, but bring about a defined filling initial state or determine. It can namely be ensured that the pressure vessels F, F2 are emptied only until complete release of the extinguishing but not the propellant. Or it can, in the interests of a quick refilling of the pressure vessel F, on the release of the extinguishing agent from the pressure vessel F - if this is not required - be dispensed with when using an additional level meter HS to determine the extinguishing agent level in the pressure vessel F. The appropriate measures are to 1 described and apply here in a similar manner.

Even while the first pressure vessel Fx is being emptied, the valves are preferably already in order to save time 23 open from all other pressure vessels F, F2, whose internal pressure above the atmospheric pressure or above the desired Befüllanfangsdrucks and / or the desired filling extinguishing agent height was determined. So they are already emptied during the ongoing treatment of the empty pressure vessel Fx, however, the treatment valves associated with them, in this case, for example, the treatment valves 42 . 43 still remain closed.

If only atmospheric pressure is measured at the first, the most emptied pressure vessel F, F2 by the pressure sensor DS, or if the desired initial charge pressure and / or the desired filling / extinguishing agent height are ascertained, its associated discharge valve becomes 23 , the drain valve 25 and additionally in the disposal line 38 existing valve closed. Its filling process can now begin.

About the compressor K is now in this first pressure vessel Fx with the treatment valve, which is still open, assigned to it, for example the treatment valve 41 , z. B. introduced air as a propellant until the pressure gauge DS the desired form of the propellant, for example, 3 bar, measures or determines or limits.

Then, in the same pressure vessel F, F2 while still open, associated with him treatment valve z. B. 41 by pressing the extinguishing agent pump P pressed the extinguishing agent until the pressure gauge DS measures the desired container filling pressure, for example, 15 bar. This monitoring can be supported / supplemented by the use of the additional, not shown Füllhöhen-measuring instrument HS in or on or at the pressure vessel F, F2. Due to the previously calculated container conditions, the correct extinguishing agent level in the pressure vessel has thus been achieved with exactly the appropriate filling pressure. The treatment valve 41 This pressure vessel F is now closed and the operational readiness of the treated pressure vessel F preferably acoustically, for example by means of a signal generator 44 , and optically, by means of light signals, for example a green light-emitting diode 46 , signaled.

The entire process described is now repeated for the pressure vessel F or F2, which was first classified as the second-lowest. Its associated treatment valve, for example 42 or 43 is now opened and measured or determined whether its internal pressure due to the previously made opening of his associated drain valve 23 has already dropped to atmospheric pressure, or whether the desired Befüllanfangsdruck and / or the desired filling extinguishing agent height has been reached. If this is not the case, now also the drain valve 25 as well as in the disposal line 38 existing valve open until the pressure gauge DS perceives atmospheric pressure in the pressure vessel F, so this is completely emptied or the desired Befüll-initial state has been reached. Thereafter, the filling takes place with subsequent preferably optical and acoustic signaling of removal and use readiness of the second pressure vessel F, F2 with a closed drain valve 23 and closed drain valve 25 analogous to the filling process of the pressure vessel F, which was first filled.

Thus, with each of the pressure vessels F, F2 proceed, which coincides with the treatment station 1a connected, be it through a pedestal 2 or one of their filling hoses 28 , The pressure vessels F, F2 are preferably treated in ascending order (first empty then fuller) of their originally determined level, as described.

With the goal, the first pressure vessel as soon as possible ready to fill, this procedure is in the described Filling principle obviously the fastest possible.

At a treatment station 1b to 5 is the pressure vessel F with its transfer valve 4 on the pedestal 2 placed. The supply line 5 leads to the node 8th to which the pressure gauge DS is connected. It is an interim container 50 provided in the extinguishing agent and propellant can be introduced. The extinguishing agent is the temporary container 50 from the extinguishing agent tank T or from the extinguishing agent supply line 14 from the extinguishing agent network through the changeover valve 11 the extinguisher line 12 fed. In the extinguisher line 12 there is a shut-off valve 49 which can be opened for filling purposes. The filling of the temporary container 50 with extinguishing agent is carried out in this form, preferably with the pressure from the extinguishing agent network, which may be a fire water network. If the extinguishing agent tank T is arranged higher than the treatment station, then the filling is carried out from the extinguishing agent tank with the natural gradient pressure. Otherwise, must in the extinguisher line 12 In addition, an extinguishing agent pump P can be arranged.

It is a powerful compressor K provided, for example, an overpressure of 18 can generate bar. From the compressor K, the propellant pressure line leads 6 to the temporary container 50 , preferably at its top 57 , In the propellant pressure line 6 is the device valve 6a that only to the temporary container 50 opens. The temporary container 50 is preferably at its top 57 with a vent valve 52 Mistake. From the temporary container 50 leads a transfer line 53 over the treatment valve 41 to the junction 8th , From the junction 8th branches the drainage pipe 22 off, in which the drain valve 23 located. From the extinguisher line 12 branches in front of or at the interim container 50 the drainage pipe 27 off, in which the drain valve 25 located. The drainage pipe 22 opens downstream of the drain valve 25 in the drainage pipe 27 at the transfer point 54 ,

From there, the emptying of the residual extinguishing agent via a line 38 and the existing in her valve into the open or in a collection container, not shown, or it is done via the optional extinguishing agent return line 9 to the extinguishing agent tank T or into the extinguishing agent supply line 14 , In the extinguishing agent return line 9 there is a Einrichtungsventil 56 that only to the extinguisher line 12 opens. In the extinguishing agent return line 9 can be provided an extinguishing agent recirculation pump PR, so that the extinguishing agent recycling even at significant pressure in the extinguishing agent supply line to the tank or the extinguishing agent power supply properly ar beitet. The filling of the temporary container 50 can be monitored or limited by means of a filling height measuring instrument HS, and / or via a pressure measuring instrument DS.

In the 5 illustrated treatment station 1b works with regard to the docking function of the pressure vessel F and the verification of the level / final pressure in the pressure vessel F as the treatment stations 1 and 1a ,

Here only the deviations are described. When initially open vent valve 52 and closed treatment valve 41 is the extinguishing agent on the extinguishing agent line 12 in the temporary container 50 pressed. The in the interim container 50 monitored by the pressure gauge DS and / or the filling height meter HS imported extinguishing agent amount of z. B. 9 liters at a volume of the pressure vessel F of z. B. 10.7 liters of course depends, inter alia, on the actual capacity of the pressure vessel F. Now, the interim container 50 at now closed vent valve 52 and open treatment valve 41 via the compressor K with propellant, such as air, pressurized. The applied overpressure first presses the extinguishing agent filling of the interim container 50 in the pressure vessel F and then the required blowing agent pressure beyond. The pressure gauge DS in the supply line 5 monitors the pressure in the pressure vessel F achieved until the required operating pressure is reached. If this is achieved, then the treatment valve 41 closed. The pressure vessel F is ready for operation.

6 shows a variant 1c the treatment station 1b with an interim container 50 , The pressure vessel F with its transfer valve 4 is on the pedestal 2 placed. The supply line 5 leads to the node 8th to which the pressure gauge DS is connected. The interim container 50 the extinguishing agent and propellant are fed separately.

The extinguishing agent becomes the temporary container 50 through the extinguisher line 12 either from the extinguishing agent tank T or the extinguishing agent supply line 14 with the inlet valve 14a fed. The changeover valve 11 determines where the extinguishing agent comes from. In the extinguisher line 12 there is an extinguishing agent pump P. The extinguishing agent pump P can be an overpressure of z. B. generate about 20 bar. On the pressure side of the extinguishing agent pump P is in front of the interim container 50 the furniture valve 26 provided that when filling extinguishing agent only to the temporary container 50 opens. The temporary container 50 is provided with a pressure gauge DS and optionally additionally with a level meter HS. The temporary container 50 is preferably at its top 57 with a vent or propellant inlet valve 52 Mistake. At the top 57 of the temporary container 50 closes the transfer line 53 on, in which the treatment valve 41 is; it ends at the junction 8th ,

From the junction 8th branches the drainage pipe 22 off, in which the drain valve 23 located. To the interim container 50 is preferably down the drain line 27 connected, in which the drain valve 25 located. The drainage pipe 22 opens downstream of the drain valve 25 in the drainage pipe 27 at the junction 54 , From there, the emptying of the extinguishing agent from the drain line 22 via the leading into the open or to a collection container, not shown leading line 38 or via the optional return line 9 to the extinguishing agent line 12 upstream of the extinguishing agent pump P.

In the extinguishing agent return line 9 is the device valve 56 that only towards the extinguisher line 12 opens. In it is the optional extinguishing agent return pump PR, so that the extinguishing agent recirculation works well even with significant pressure in the extinguishing agent supply line to the tank or to the extinguishing agent mains connection. The filling of the temporary container 50 can be monitored by means of the filling height measuring instrument HS or alternatively via a pressure measuring instrument DS.

On the function of the treatment station 1c Again, only the deviations from the treatment stations 1a and 1b described.

First, the system consisting of the interim container 50 , the transfer line 53 and the pressure vessel 50 preferably be emptied and depressurized, for example, are at atmospheric pressure. This emptying takes place via the lines 27 and 22 in connection with pipe 38 (or alternatively over the line 9 ) and via the vent or propellant inlet valve 52 , If the system is totally emptied of extinguishing agent or filled with propellant, such as air, then the valves 23 . 25 and 52 sealed pressure-tight. In the system of temporary container 50 , Transfer line 53 and pressure vessel F is thus included a certain, measured blowing agent volume.

The conclusion of the emptying process can on the preferably at the bottom of the interim container 50 attached pressure measuring instrument DS and / or, if the propellant is detectable by a level meter HS, are also detected by means of the filling height measuring instrument HS.

That by the extinguisher line 12 zufließ The extinguishing agent pressurized by the extinguishing agent pump P compresses when it rises in the interim container 50 the existing propellant. The so in the interim container 50 compressed propellant, in this case, for example, air, by means of the further flowing extinguishing agent with further increased extinguishing agent pressure and open treatment valve 41 via the transfer line 53 and the supply line 5 pressed into the pressure vessel F. Immediately before the first extinguishing agent is pressed into the pressure vessel F, the initially desired propellant excess pressure of z. B. about 3 bar, since the previously existing propellant content of the interim container 50 was pressed into the pressure vessel F. The correct height of this first introduced into the pressure vessel F propellant pressure is determined by the choice of the appropriate volume of the interim container 50 and its previously performed venting respectively filling with the propellant, for example air, via the venting or propellant inlet valve 52 , The extinguishing agent is pressed into the pressure vessel F after the propellant. The filling meter HS monitors or limits the amount of the introduced extinguishing agent at a tank internal pressure of F of z. B. 15 bar or correct level of the extinguishing agent in the pressure vessel F. In this case, can be dispensed with the use of the pressure measuring instrument DS during filling up to operational readiness, because from the beginning of the filling in the system volume of propellant, such as air, can be closed at how much a brought extinguishing agent, so what level, the operating pressure has been reached with certainty.

The treatment valve 41 is now closed, the extinguishing pump P is turned off. The pressure vessel F is ready for operation. For the realization of the desired conditions in the pressure vessel F plays the volume design of the interim container 50 So an essential role.

7 shows another variant 1d the previously described treatment stations. The pressure vessel F with its transfer valve 4 is on the pedestal 2 placed. The supply line 5 leads to the node 8th to which the pressure gauge DS is connected. It is a mixing device 60 provided, are mixed in the propellant, such as air, and a preferably liquid extinguishing agent. The mixing device 60 For example, you can work according to the injection principle. The active injection area is not shown in detail; he is in the mixing device. Instead of an injection area can in the mixing device 60 Also, a non-illustrated suction area, for example with a Venturi nozzle, be provided. The mixing ratio of blowing agent and extinguishing agent is by means of an actuator 62 adjustable. Depending on the setting of the changeover valve 11 the extinguishing agent from the Löschwassertank T or the Zuwasserleitung 14 via the extinguishing agent line 12 the mixing device 60 fed. A propellant line 61 leads the mixer 60 For example, air as blowing agent. The mixing device 60 Downstream is the suction side 63 the extinguishing agent pump P. The extinguishing agent pump P should be a mixed delivery pump, which can generate, for example, an overpressure of 20 bar. This extinguishing agent pump P sucks extinguishing agent and blowing agent mixed from the mixing device 60 and push it through a fitting valve 64 into the transfer line 53 with the treatment valve 41 , If this is open, then the mixture of extinguishing agent and propellant flows over the node 8th and the supply line 5 to the pedestal 2 from where it passes through the replacement valve 3 and the transfer valve 4 gets into the pressure vessel F. The pressure gauge DS measures or limits the increasing pressure in the pressure vessel F and ensures by closing the treatment valve 41 for switching off the supply of extinguishing agent and propellant as soon as the operating pressure has been reached. The pressure vessel F is then ready.

In this variant, emptying and disposal is preferably provided. From the junction 8th branches the drainage pipe 22 off, in which the drain valve 23 located. From the junction 8th also branches the drainage pipe 27 off, in which the drain valve 25 located. The drainage pipe 22 opens downstream of the drain valve 25 in the drainage pipe 27 at the transfer point 54 ,

From there, the emptying of the extinguishing agent from the drain line 22 over the line 38 take place outdoors or in a collecting container, not shown, or alternatively via the extinguishing agent return line 9 to the extinguishing agent tank T or to the extinguishing agent supply line 14 , In the extinguishing agent return line 9 are the set up valve 56 that only to the extinguisher line 12 opens and the optional extinguishing agent return pump PR.

For all treatment stations, those in the base 2 provided valves 3 with the associated transfer valves 4 The two parts of quick-release couplings that are either "latching", that is, locking, or non-latching, non-latching couplings are preferred because they are easy to use, but then the safeguards against flying away or lifting the pressure vessel are 2 or 3 needed. This also means that the filling or treatment process of the pressure vessel F, F2 may start only when the locking is done up, or in the case of using snap-lock quick-couplings, the Kupp ment (s) securely locked, locked / are. The quick release coupling near the bottom, so in containers F, but could also be restraining; then, of course, the safeguards went up. For containers F2 with hose connection 28 not on a pedestal 2 should be put on the quick release coupling to the filling hose 28 preferably be latching.

• 1. Die gewählten Treibmittel und Löschmittel sollten unter den im Behandlungsvorgang auftretenden Betriebsbedingungen vorzugsweise nicht nennenswert ineinander löslich sein.
• 2. Die gewählten Treibmittel und Löschmittel sollten im Bereich der im Behandlungsvorgang auftretenden Betriebsbedingungen vorzugsweise nicht verdampfen oder kondensieren.

As extinguishing agent can be used in all embodiments, an extinguishing agent for fire use or even for the practice use. It comes preferably at 298 K and 1013 mbar liquid extinguishing agents, such as water, into consideration. As propellant gases, such as halons and air can be used. For the correct implementation of the determination of the introduced into the pressure vessel F amounts of the respective component by means of the pressure gauges DS described, it is recommended, however, to select the respective combination of blowing agent and extinguishing agent so that the following conditions are met:

• 1. The selected propellants and extinguishing agents should preferably not be significantly soluble in each other under the operating conditions occurring in the treatment process.
• 2. The selected propellants and extinguishing agents should preferably not evaporate or condense in the range of operating conditions occurring in the treatment process.

In the practice use, the treatment stations can be 1 and 1a but also 1b . 1c and 1d to use in an excellent way to train an effective Übungslöscheinsatz and fire use. at 1c However, the necessary between the filling operations extinguishing agent emptying process in practice often quite bulky Interimsbehälters 50 be unnecessarily time consuming. For the treatment station according to FIG. 1b In the interest of a speedy filling process, a compressor K with very high performance data, ie with high throughput at relatively high pressure, is needed.

It should also be emphasized that at the treatment stations for introducing the correct ratio of an extinguishing agent and a propellant, such as air, in the pressure vessel F, F2 in the sense of 5 in particular, a single compressor K is needed. Does this happen in the sense of 6 or 7 In particular, a single extinguishing medium pressure pump is required to achieve the same objective. Thus, under certain circumstances, a very economical construction of the treatment station can be achieved.
