Description
Technical Field
The invention relates to a valve device, in particular for extinguishing fluid, comprising a housing having a container connection for connecting to a pressurized fluid container in a height direction, with a fluid outlet oriented substantially transversely to the container connection. The invention also relates to a fire extinguishing system with such a valve device.
In the field of stationary fire extinguishing systems, so-called quick-opening valves are used, which can provide a pressurized extinguishing agent in a very short time.
The quick-opening valve has a fire suppression fluid inlet, a fire suppression fluid outlet, and a flow chamber extending from the fire suppression fluid inlet to the fire suppression fluid outlet. In order to distinguish between a rest state of the fire suppression fluid container and a triggered state of the fire suppression fluid container, known quick-opening valves have a valve piston and a valve seat. The valve piston can be moved between a release position or an open position and a blocking position, such that the valve piston and the valve seat lie against one another in a fluid-tight manner in the blocking position and are spaced apart from one another in the open position. In the open position, the fire suppression fluid inlet and the fire suppression fluid outlet can be fluidly connected to each other.
Background
In known quick-opening valves, the valve piston is directed parallel to or along the common axis towards the fire suppression fluid outlet. In this arrangement, the positioning of the valve piston in the blocking position requires a continuous supply of reaction force. Therefore, a higher opening force than the reaction force is required to open the valve piston. Therefore, in order to actuate such a quick-opening valve, high energy must be consumed. Such valves are also shown in EP0582041a1 or EP2428714a1, in which the valve piston and the container connection for the extinguishing agent container are arranged in series with one another.
Disclosure of Invention
The object of the invention is to provide a compact valve device which can be actuated with a minimum of energy consumption, independently of the internal pressure of the connected extinguishing agent container.
This object is achieved by the features given in claim 1 and claim 10. Further advantageous designs of the invention are described in the dependent claims.
According to one aspect of the invention, a valve device, in particular for a fire suppressant fluid, is provided. The valve device can preferably be designed as an axial valve or as a cross valve or as a radial valve or as a transverse valve.
The valve device has a housing with a container connection for connection to a pressurized fluid container in the height direction of the valve device. The height direction preferably coincides with the extension direction of the fluid container. The fluid container can be designed as a fire-extinguishing agent container which holds a liquid, gaseous or powdery fire-extinguishing agent or fire-extinguishing agent fluid under pressure.
Furthermore, the valve device has a fluid outlet oriented substantially transversely to the container connection. The fluid outlet may be connected to the container connection via a pressurized flow chamber. The valve device is further provided with a valve piston which is designed to be movable in a transverse direction between a blocking position and an open position and which in the blocking position closes the fluid outlet in a fluid-tight manner with respect to the container connection. The transverse direction is preferably oriented orthogonally to the height direction.
The counter-pressure means is positioned on the opposite side of the valve piston to the fluid outlet, which keeps the valve piston in the blocking position, wherein the valve piston is arranged to assume (at least partly assume) the open position by an increase in pressure at the fluid outlet relative to the counter-pressure means.
The pressure increase can be generated by an overpressure at the fluid outlet or by an underpressure in or on the counter-pressure device.
The valve means can be switched between the blocking position and the open position without damage or reversibly. There is no need to replace components, such as rupture discs.
The overpressure in the extinguishing medium container acts in both directions, i.e. to the right and to the left, relative to a valve piston arranged transversely to the valve piston seat. Overall, this results in a force on the valve piston corresponding to zero. As a result of this measure only the frictional force for closing the seal and the spring force of the retaining spring or counter-pressure means need to be overcome for actuating the valve means. Thereby, the valve arrangement can be actuated with a minimum of energy requirements.
The counter-pressure means only need to exert a minimum force on the valve piston, since no force of the fluid container acts on the valve piston in the blocking position. The counterpressure device preferably has a resetting means which is provided to act on the valve piston in order to exert a resetting force on the valve piston in the direction of the blocking position.
The design of the valve device can be particularly compact and technically simple when the valve piston can be moved in the bore or recess between the blocking position and the open position. Thus, the valve piston does not require a defined valve seat positioned in the piston housing. The valve piston may be disposed directly in the bore of the piston housing.
According to another embodiment, the counter-pressure means is arranged for receiving pressure from the pressurized release line for positioning the valve piston in the blocking position against the force of the holding spring. If a triggering takes place in such a case, a pressure drop occurs in the trigger line, i.e. by means of which the holding spring can no longer be pressed in, so that the valve piston is moved by the holding spring into the open position.
Alternatively, the counter-pressure device has a negative pressure. To this end, the fluid outlet may also be subjected to a negative pressure. If triggering occurs, the underpressure in the fluid outlet is replaced by ambient pressure, for example by a bursting element in a line connected to the fluid outlet, whereby the counter-pressure means can no longer hold the valve piston in the blocking position and the valve piston is displaced into the open position.
The valve device can be realized in a technically particularly simple manner when the valve piston can be moved into the open position by an overpressure at the fluid outlet, wherein the valve piston can be locked in the open position by the overflow pressure. Once the friction of the seal on the valve piston and the spring force of the counter-pressure means are overcome, the overflow pressure through the flow chamber may keep the valve piston in the open position until the overpressure of the fluid container is substantially balanced with the ambient pressure. The valve piston can then be moved again into the blocking position by means of the counter-pressure device.
According to a further embodiment, the valve piston is arranged inside the flow chamber or downstream of the flow chamber in the outflow direction of the extinguishing fluid. By arranging the valve piston inside the flow chamber, the height of the piston housing and the valve device can be reduced.
When the valve piston has a flow surface which faces the container connection when the valve piston is in the open position, extinguishing fluid which flows through the flow chamber when the valve piston is in the open position can escape with particularly little loss. For example, the valve piston can have a circular surface facing the container connection, which is surrounded by the outflowing extinguishing fluid in the open position. In particular, pressure losses at the valve device can be minimized by this measure.
The valve device can be implemented particularly reliably if the housing or the piston housing has an overpressure protection by means of which the container connection can be connected to the fluid outlet or the container connection can be connected to the outside environment in the event of an overpressure. The overpressure protection can be designed, for example, in the form of an overpressure opening with an overpressure valve or a bursting disk. The overvoltage protection can be designed as a safety device against overvoltage, and can also be designed as a bursting cap, a bursting element, a bursting screw, a bursting cartridge, etc. In the event that a predetermined pressure is exceeded in the flow chamber, in the fluid inlet and/or in the container connection, it is then possible to trigger or deactivate the overpressure protection and open the fluid-conducting connection to the outside environment. The overpressure protection can preferably act independently of the state or position of the valve piston.
According to a further embodiment, a venting valve and a triggering device for controlling the venting valve are arranged in the housing, wherein the venting valve and/or the triggering device are arranged laterally offset from the container connection in the housing. The height of the valve device can be minimized due to this positioning of the venting valve and the triggering device. In particular, the venting valve and the triggering device can be tilted laterally with respect to the fluid outlet.
The valve device may be arranged directly on the fluid container or the extinguishing agent container, or it may be connected indirectly to the fluid container, for example via a hose connection or a pipe connection.
The valve device can be particularly effectively connected to an existing reporting or alarm system when an alarm switch is arranged in the housing, which alarm switch is provided for registering the open position of the valve piston or a pressure loss in the flow chamber or a pressure increase in the fluid outlet. As a result of this measure, an electrical or mechanical signal can be generated, for example when the valve piston is moved into the open position. The alarm switch may be, for example, a hall sensor or an infrared sensor or a grating electronically connected to the controlling appliance or driver. The control device or the drive can be integrated into the alarm switch or designed as an external device.
According to another aspect of the present invention, a fire suppression system is provided. The fire extinguishing system has a valve device according to the invention, wherein the extinguishing agent container is fluidly connected to the container connection of the valve device. The fluid outlet of the valve device is connected to at least one fire extinguishing line.
The fire extinguishing system further has a trigger line arranged to establish an imbalance between the pressure in the counter-pressure device and the pressure in the fluid outlet, by means of which imbalance the valve piston can be deflected from the blocking position to the open position. By this measure, a fire extinguishing system which can be operated in an energy-saving manner can be provided.
When the counter-pressure means of the valve device is subjected to a negative pressure and the fire extinguishing line is used as a trigger line subjected to a negative pressure, the fire extinguishing system can be constructed with a minimum number of lines. For example, the trigger line can have locally distributed bursting elements which burst in the event of a temperature increase. By the bursting of the at least one bursting element, a connection is established between the fire extinguishing line functioning as the triggering line and the surroundings of the fire extinguishing system, so that the pressure in the fire extinguishing line and the fluid outlet is increased. This imbalance between the counter-pressure means and the pressure in the fluid outlet causes the return spring of the valve piston to move the valve piston to the open position. Thus, fire suppressant fluid may pass from the fluid container into the fluid outlet and into the fire suppression line. The fire suppressant fluid may escape from the fire suppression line via a bursting element that bursts or through nozzles and/or sprinklers provided for this purpose.
The fire extinguishing system may function on an alternative principle of action when the counter-pressure means of the valve device, which is in fluid connection with the trigger release line, is applied with an overpressure to compress the retaining spring of the valve piston. By this measure, the trigger line can be separated from the extinguishing line, so that the extinguishing fluid can be conducted more specifically. The trigger line, for example in the event of triggering, becomes unsealed, so that overpressure in the counter-pressure device can escape. The fluid outlet is thereby provided with an overpressure relative to the counter-pressure device and the valve piston can be deflected into an open position, whereby the extinguishing fluid escapes from the fluid container.

Detailed Description
Fig. 1a and 1b show a sectional view of a valve device 10 according to an embodiment of the invention. In the illustrated embodiment, the valve device 10 is configured for use with liquid, gaseous, or powdered fire suppressant fluids.
The valve device 10 has a housing 11 with a container connection 12 which is configured for connection in the height direction H with a pressurized fluid container 20. The valve device 10 is designed as a quick-opening valve, in particular as a radial valve or as a cross valve.
Furthermore, a fluid outlet 13 is provided in the housing 11. The fluid outlet 13 is oriented substantially transversely to the container connection 12. The fluid outlet 13 may extend in a transverse direction Q, which is oriented transversely to the height direction H.
The fluid outlet 13 may be connected with the container connection 12 via a pressurized flow chamber 14. The valve device 10 also has a valve piston 15, which is also arranged in the housing 11. The valve piston 15 is positioned in a bore 16 in the housing 11 and can be positioned fluid-tightly in the blocking position via a housing-side sealing means 17.
In the shown embodiment, the valve piston 15 is arranged in the blocking position and closes, together with the sealing means 17, the flow chamber 14 extending from the fluid container 20 to the fluid outlet 13. Thereby inhibiting fluid from entering the fluid outlet 13 from the fluid container 20 via the flow chamber 14.
The valve piston 15 is designed to be movable in the transverse direction Q between a blocking position and an open position. In particular, the valve piston 15 can be moved between the open position and the blocking position in such a way that the valve piston 15 does not require a defined valve seat, since the sealing effect is achieved by the sealing means 17.
In the embodiment shown, the valve piston 15 is designed as a hollow piston. Depending on the field of application, the valve piston 15 can also be made of solid material.
On the side of the valve piston 15 opposite the fluid outlet 13, a counter-pressure device 30 is positioned, which holds the valve piston 15 in the blocking position. For this purpose, an internal retaining spring 31 in the counter-pressure device 30 presses in the transverse direction Q against the valve piston 15 in order to lock it in the blocking position. The retaining spring 31 may press directly on the valve piston 15 or transmit a force to the valve piston 15 via an intermediate piston 32.
The valve piston 15 is also sealed with respect to the counter-pressure means 30, for example via a sealing means 17, to inhibit fluid exchange between the counter-pressure means 30 and the fluid container 20.
The retaining spring 31 is preferably designed in such a way: normal air pressure in the fluid outlet 13 is already able to achieve pressing of the valve piston 15 against the holding spring 31. The valve piston 15 is thus arranged to assume the open position by an increase in pressure at the fluid outlet 13 relative to the counter-pressure means 30.
A top view of the valve device 10 is shown in fig. 1 b. Here, a pressure indicator 33, a manual trigger switch 34 and an alarm switch 35 are shown, which are arranged on the housing 11, for the pressure prevailing in the fluid container 20 in the flow chamber 14.
The pressure indicator 33 is for example a pressure gauge with a mechanical display. By means of a mechanically movable pointer, it is monitored whether there is sufficient pressure in the extinguishing medium container or fluid container 20.
The alarm switch 35 is provided for registering the open position of the valve piston 15 or a pressure loss in the flow chamber 14 or a pressure increase in the fluid outlet 13. The alarm switch 35 is designed as an appliance for issuing an alarm in the event of a trigger.
The alarm switch 35 is implemented, for example, as an alarm pressure switch in the form of a mechanical limit switch monitoring. In this case, the presence of pressure in the outlet area or in the fluid outlet 13 is monitored by means of a mechanically displaceable switch. When the valve device 10 is triggered, i.e. when the valve piston 15 is opened, the alarm switch 35 is activated. For example, the alarm function is monitored manually and/or visually and/or electronically.
The sectional view of fig. 1a is shown in fig. 2a and 2b to illustrate the open position and the blocking position of the valve piston 15. Wherein the valve piston 15 is shown in a blocking position in fig. 2a and in an open position in fig. 2 b.
Fig. 2a shows that the valve piston 15 has an annular flow surface 18 which faces the container connection 12 when the valve piston 15 is in the open position. In the exemplary embodiment shown, the flow area 18 is embodied as a rounding or phasing of the end faces of the valve piston 15.
Figures 3a, 3b and 3c show cross-sectional views to illustrate details of the valve device of figure 1. In fig. 3a and 3c, an additional inflation valve 38 is provided, which is protected from external contamination by a blind screw 39.
When fluid container 20 is filled with fire suppressant, a motive gas may be introduced through inflation valve 38 to pressurize fluid container 20. For example, compressed air or inert gas may be used as the power gas.
In particular, fig. 3b shows the positioning of the exhaust valve 36 in the housing 11 and the triggering device controlling the exhaust valve 36.
The triggering device is designed as an overpressure protection 37, by means of which the container connection 12 can be brought into communication with the fluid outlet 13 or the container connection 12 can be brought into communication with the outside environment in the event of an overpressure.
In the exemplary embodiment shown, the overpressure protection 37 is designed as a bursting disk or bursting element, which is connected to the venting valve 36 in order to release the overpressure into the external environment.
In fig. 4a schematic view of a fire extinguishing system 100 with the valve device 10 of fig. 1 is shown. The fire extinguishing system 100 has a valve device 10, wherein a fire extinguishing agent container 20 is fluidly connected to a container connection 12 of the valve device 10. The fluid outlet 13 of the valve device 10 is connected to at least one fire extinguishing line 110, 111.
In the embodiment shown, the fire suppression lines 110, 111 are simultaneously designed as trigger lines and have a thermally sensitive bursting element 113 arranged in series with the nozzles 112 of the fire suppression lines 110, 111.
The counter-pressure means 30 of the valve device 10 is applied with a negative pressure and the fire extinguishing lines 110, 111 are used as triggering lines subjected to a negative pressure. By the bursting of the at least one bursting element 113, a connection is established between the fire suppression lines 110, 111 functioning as triggering lines and the surroundings of the fire suppression system 100, so that the pressure in the fire suppression lines 110, 111 and in the fluid outlet 13 is increased. This imbalance between the pressure in the counter-pressure means 30 and the fluid outlet 13 causes the retaining spring 31 of the counter-pressure means 30 to move the valve piston 15 to the open position. Thus, fire suppressant fluid can pass from the fluid container 20 into the fluid outlet 13 and into the fire suppression lines 110, 111. The fire suppressant fluid can escape from the fire suppression lines 110, 111 via the bursting element 113 which bursts or via nozzles 112 and/or sprinklers provided for this purpose.
Furthermore, in fig. 4 it is clear that a stand pipe 21 leading to the flow chamber 14 is arranged in the fluid container 20. Depending on the application, the riser 21 may be rigid or flexible. Depending on the location of the fluid container 20, the riser 21 may follow the route or location of the fire suppressant fluid in the fluid container 20.
Fig. 5a and 5b show a schematic cross-sectional view of a fire extinguishing system 100 with a valve device 10 according to another embodiment of the invention. In which the valve device 10 is shown in fig. 5b in the blocking position of the valve piston 15, while the valve device in fig. 5b is in the open position of the valve piston 15. In contrast to the fire extinguishing system 100 shown in fig. 4, here the fire extinguishing line 110 and the triggering line 114 are designed separately from one another.
The counter-pressure means 30 of the valve device 10 is applied with an overpressure to compress the retaining spring 31 of the valve piston 15. The counter-pressure device 30 is connected in a fluid-conducting manner to the trigger line 114. By this measure, the trigger line 114 can be separated from the extinguishing line 110. In fig. 5a, the valve device 10 is in a closed or non-activated state, whereby the valve piston 15 is arranged in the blocking position.
Fig. 5b shows the fire extinguishing system 100 with the valve device 10, wherein the valve piston 15 has been displaced to the open position. For example, in the event of a triggering event, the trigger line 114 becomes unsealed, since the bursting element 113 bursts due to the effect of heat and causes leakage. Whereby the overpressure in the counter-pressure device 30 can escape. The fluid outlet 13 is thus provided with an overpressure in comparison to the counter-pressure device 30 and the valve piston 15 can be deflected against the retaining spring 31 into the open position to enable the escape of extinguishing fluid from the fluid container 20.
Furthermore, it is clear from fig. 5a and 5b that the valve piston 15 has an alternative annular flow surface 18 designed as an annular groove and facilitates the flow of extinguishing fluid when the valve piston 15 is in the open position, for example by suppressing turbulence.
