Definitions

  • the invention relates to a valve arrangement, in particular for an extinguishing agent fluid, having a housing with a container connection for connection to a pressurized fluid container along a vertical direction, with a fluid outlet aligned essentially transversely to the container connection. Furthermore, the invention relates to an extinguishing system with such a valve arrangement.
  • quick-opening valves In the field of stationary extinguishing systems, so-called quick-opening valves are used, which can provide a pressurized extinguishing agent in the shortest possible time.
  • Such quick opening valves have an extinguishing fluid inlet, an extinguishing fluid outlet and a flow chamber which extends from the extinguishing fluid inlet to the extinguishing fluid outlet.
  • the known quick-opening valves have a valve piston and a valve seat.
  • the valve piston can be moved between a release position or open position and a blocking position in such a way that the valve piston and the valve seat are in fluid-tight contact with one another in the blocking position and are spaced apart from one another in the open position. In the open position, the extinguishing fluid inlet and the extinguishing fluid outlet can be fluidly connected to one another.
  • valve piston In the known quick opening valves, the valve piston is directed parallel to or along a common axis to the extinguishing fluid outlet. With such an arrangement, the positioning of the valve piston in the blocking position requires a continuous supply of a counterforce. As a result, in order to open the valve piston, an opening force that is higher than the counteracting force is required. Thus, a high expenditure of energy must be applied to such operate the quick opening valve.
  • a valve is also in the EP 0 582 041 A1 or the EP 2 428 714 A1 shown, in which the valve piston and the tank connection for an extinguishing agent tank are arranged in series with one another.
  • the invention is based on the object of creating a compact valve arrangement which can be actuated independently of the internal pressure of a connected extinguishing agent container with a minimum expenditure of energy.
  • a valve arrangement in particular for an extinguishing agent fluid, is provided.
  • the valve arrangement can preferably be designed as an axial valve or transverse valve or as a radial valve or transverse valve.
  • the valve arrangement has a housing with a tank connection for connection to a pressurized fluid tank along a height direction of the valve arrangement.
  • the height direction preferably runs congruently with an elongate extent of the fluid container.
  • the fluid container can be designed as an extinguishing agent container which contains a liquid, gaseous or powdered extinguishing agent or extinguishing agent fluid under pressure.
  • the valve arrangement also has a fluid outlet which is oriented essentially transversely to the container connection.
  • the fluid outlet can be connected to the container connection via a pressurized flow chamber.
  • a valve piston is also provided, wherein the valve piston is designed to be movable along a transverse direction between a blocked position and an open position and in a blocked position closes the fluid outlet in a fluid-tight manner with respect to the container connection.
  • the transverse direction is preferably aligned orthogonally to the vertical direction.
  • a counter-pressure device On a side of the valve piston opposite the fluid outlet, a counter-pressure device is positioned, which holds the valve piston in the Blocking position holds, wherein the valve piston is set up to take the (at least partially) open position by a pressure increase at the fluid outlet relative to the counter-pressure device.
  • the pressure increase can be generated by an overpressure at the fluid outlet or by a negative pressure in or on the counter-pressure device.
  • the valve arrangement can be switched non-destructively or reversibly between the closed position and the open position. An exchange of components, such as bursting discs, is not necessary.
  • the counter-pressure device only has to exert a minimal force on the valve piston, since no forces act through the fluid container on the valve piston in the blocking position.
  • the counter-pressure device preferably has restoring means which are set up to act on the valve piston in order to apply a restoring force to the valve piston in the direction of the blocked position.
  • the valve arrangement can be designed to be particularly compact and technically simple if the valve piston can be moved in a bore or a recess between a blocked position and an open position.
  • no defined valve seat is required for the valve piston, which is positioned in a piston housing.
  • the valve piston can be placed directly in a bore in the piston housing.
  • the counter-pressure device is set up to generate a pressure from a pressurized triggering line record to position the valve piston against a force of a retaining spring in the locked position. If it is triggered in this way, there is a drop in pressure in the triggering line, as a result of which the retaining spring can no longer be pressed in, as a result of which the valve piston is moved into an open position by the retaining spring.
  • the counter-pressure device has a negative pressure.
  • the fluid outlet can also be subjected to a negative pressure. If it is triggered, the negative pressure in the fluid outlet is replaced by ambient pressure, for example by a bursting element in a line connected to the fluid outlet, as a result of which the counter-pressure device can no longer hold the valve piston in the blocked position and the valve piston is thus moved to the open position.
  • the valve arrangement can be realized technically in a particularly simple manner if the valve piston can be moved into the open position by an overpressure at the fluid outlet, the valve piston being able to be locked in the open position by an overflow pressure. If the frictional force of the seals on the valve piston and the spring force of the counter-pressure device are overcome, the overflow pressure through the flow chamber can hold the valve piston in the open position until the fluid container has essentially equalized its overpressure with the ambient pressure. The valve piston can then be moved again into a blocking position by the counter-pressure device.
  • valve piston is arranged within the flow chamber or downstream of the flow chamber along an outflow direction of the extinguishing agent fluid.
  • the extinguishing agent fluid flowing through the flow chamber when the valve piston is in the open position can escape with particularly little loss if the valve piston has a flow area which, in the open position of the valve piston, faces the container connection.
  • the valve piston can have a round surface facing the container connection Open position flows around the outflowing extinguishing agent fluid.
  • the pressure loss at the valve arrangement can be minimized by this measure.
  • the valve arrangement can be designed to be particularly safe if the housing or the piston housing has overpressure protection, through which the container connection can be connected to the fluid outlet or the container connection to the outside environment in the event of excess pressure.
  • the overpressure protection can be designed, for example, in the form of an overpressure opening with an overpressure valve or a bursting disk.
  • the overpressure protection can be designed as a safety device against overpressure and can also be designed as a bursting cap, a bursting element, a bursting screw, a bursting socket and the like. If a predefined pressure inside the flow chamber, inside the fluid inlet and/or inside the container connection is exceeded, the overpressure protection can trigger or fail and expose a fluid-carrying connection to the environment.
  • the overpressure protection can preferably act independently of the state or the position of the valve piston.
  • a vent valve and a triggering device controlling the vent valve are arranged in the housing, the vent valve and/or the triggering device being offset in the transverse direction with respect to the container connection in the housing.
  • the height of the valve arrangement can be minimized by positioning the vent valve and the triggering device in this way.
  • the vent valve and the triggering device can be angled laterally relative to the fluid outlet.
  • the valve arrangement can be arranged directly on a fluid container or extinguishing agent container or can be connected to the fluid container indirectly, for example via a hose connection or a pipe connection.
  • the valve assembly can be particularly efficiently connected to an existing reporting system or alarm system when an alarm switch is arranged in the housing, which is adapted to the open position of the valve piston or a pressure loss in the To register flow chamber or a pressure increase in the fluid outlet.
  • This measure allows an electrical or mechanical signal to be generated, for example when the valve piston is moved to the open position.
  • the alarm switch can be a Hall sensor or an infrared sensor or a light barrier, for example, which is electronically connected to a control device or a driver.
  • the control device or the driver can be integrated into the alarm switch or be designed as an external device.
  • an extinguishing system has a valve arrangement according to the invention, in which an extinguishing agent container is connected in a fluid-conducting manner to a container connection of the valve arrangement.
  • a fluid outlet of the valve assembly is connected to at least one extinguishing line.
  • the extinguishing system also has a trigger line that is set up to create an imbalance between the pressure in the counter-pressure device and the pressure in the fluid outlet, through which the valve piston can be deflected from a blocked position into an open position. This measure makes it possible to provide an extinguishing system that can be operated in an energy-efficient manner.
  • the extinguishing system can be designed with a minimum number of lines if the back pressure device of the valve assembly is subjected to a negative pressure and the extinguishing line functions as a negative pressure applied trigger line.
  • the tripping line can have locally distributed bursting elements that break when the temperature rises. The rupture of at least one bursting element creates a connection between the extinguishing line, which acts as a triggering line, and the environment of the extinguishing system, so that the pressure in the extinguishing line and the fluid outlet increases.
  • Such an imbalance between the pressure in the back pressure device and the fluid outlet causes a return spring of the valve piston to move it to an open position.
  • the extinguishing agent fluid can thus get out of the fluid container into the fluid outlet and into the extinguishing line. That can be done from the extinguishing line Extinguishing agent fluid escape via the broken bursting element or via nozzles and/or sprinklers provided for this purpose.
  • the extinguishing system can function based on an alternative operating principle when the counter-pressure device of the valve arrangement is subjected to excess pressure in order to compress a retaining spring of a valve piston, the counter-pressure device being fluidly connected to a trigger line.
  • This measure allows the triggering line to be separated from the extinguishing line, which enables the extinguishing agent fluid to be routed in a more targeted manner.
  • the triggering line leaks, for example, when it is triggered, allowing the excess pressure in the counter-pressure device to escape.
  • the fluid outlet has an overpressure compared to the counter-pressure device and can deflect the valve piston into the open position in order to allow the extinguishing agent fluid to escape from the fluid container.
  • FIGS. 1a and 1b 12 show sectional views of a valve assembly 10 according to an embodiment of the invention.
  • the valve assembly 10 is provided in the illustrated embodiment for a liquid, gaseous or powder extinguishing agent fluid.
  • the valve assembly 10 has a housing 11 with a tank port 12 which is configured for connection along a height direction H to a pressurized fluid tank 20 .

  • the valve piston 15 is positioned in a bore 16 in the housing 11 and can be positioned in a locked position in a fluid-tight manner via sealing means 17 on the housing side.
  • valve piston 15 is arranged in a blocking position and, in connection with the sealing means 17, closes the flow chamber 14, which extends from the fluid container 20 to the fluid outlet 13. This prevents a fluid flow from the fluid container 20 into the fluid outlet 13 via the flow chamber 14 .
  • the valve piston 15 is designed to be movable along the transverse direction Q between the blocked position and an open position. In particular, the valve piston 15 can be moved between the open position and the closed position in such a way that the valve piston 15 does not require a defined valve seat since the sealing effect is provided by the sealing means 17 .
  • the valve piston 15 is designed as a hollow piston in the illustrated embodiment. Depending on the field of application, the valve piston 15 can also be made from a solid material.
  • a counter-pressure device 30 is positioned on a side of the valve piston 15 opposite the fluid outlet 13 and holds the valve piston 15 in the blocked position.
  • an internal retaining spring 31 presses in the counter-pressure device 30 in the transverse direction Q against the valve piston 15 in order to lock it in the blocked position.
  • the retaining spring 31 can press directly on the valve piston 15 or transmit the force to the valve piston 15 via an intermediate piston 32 .
  • valve piston 15 is also sealed against the counter-pressure device 30 by means of sealing means 17 in order to prevent a fluid exchange between the counter-pressure device 30 and the fluid container 20 .
  • the retaining spring 31 is preferably designed in such a way that even a regular air pressure in the fluid outlet 13 enables the valve piston 15 to be pressed against the retaining spring 31 .
  • the valve piston 15 is thus set up to assume the open position relative to the counter-pressure device 30 as a result of a pressure increase at the fluid outlet 13 .
  • FIG. 1b A top view of the valve assembly 10 is shown. It is illustrated that a pressure indicator 33 for the applied pressure of the fluid container 20 in the flow chamber 14, a manual release switch 34 and an alarm switch 35 are arranged on the housing 11.
  • the pressure indicator 33 is, for example, a pressure gauge with a mechanical display.
  • a mechanically movable indicator needle is used to monitor whether there is enough pressure in the extinguishing agent container or fluid container 20 .

  • the valve piston 15 in a locked position and in the Figure 2b illustrated in an open position.
  • FIG. 1 shows that the valve piston 15 has a flow area 18 which faces the container connection 12 when the valve piston 15 is in the open position.
  • the flow area 18 is implemented as a rounded end or phasing of the valve piston 15 .
  • FIGS. 3a, 3b and 3c 12 show sectional views for illustrating details of the valve assembly 1 .
  • an additional charging valve 38 is provided, which is protected from dirt by a blind screw 39 on the outside.
  • a propellant gas for pressurizing the fluid container 20 can be introduced through the charging valve 38 .
  • compressed air or an inert gas can be used as the propellant gas.
  • the triggering device is designed as an overpressure protection 37, through which, in the event of overpressure, the container connection 12 can be connected to the fluid outlet 13 or the container connection 12 to the outside environment.
  • the overpressure protection 37 is designed as a bursting disc or a bursting element, which is connected to the vent valve 36 in order to release an overpressure to the outside environment.

  • the rupture of at least one bursting element 113 creates a connection between the extinguishing line 110, 111, which acts as a trigger line, and the environment of the extinguishing system 100, so that the pressure in the extinguishing line 110, 111 and the fluid outlet 13 increases.
  • Such an imbalance between the pressure in the counter-pressure device 30 and the fluid outlet 13 causes the retaining spring 31 of the counter-pressure device 30 to move the valve piston 15 into the open position.
