Definitions
- the invention relates to an extinguishing system with at least two spray heads, each with a pressurized water connection, with a distribution chamber, from the distribution channels go out to spray nozzles, and with one the pressure water passage from Pressurized water connection to the control chamber, spring-loaded and via at least one control device controllable control piston are provided, the can be acted upon on both sides via two cylinder chambers, one of which is the cylinder chamber to pressurize the piston in the opening direction on the one hand with the pressurized water connection and on the other hand via a throttle line in the control piston to the other cylinder chamber communicates
- control piston In known spray heads (WO 93/10861), the control piston is supported on one Glass break protection as a control device against which he uses a load spring is pressed. In order to overload the glass breakage protection according to the Spring load and the pressure water acting in the same direction To avoid the control piston, the control piston is on both sides over two cylinder chambers acted upon, of which the cylinder chamber for piston loading in the opening direction not only with the pressurized water connection, but also with the other Cylinder chamber is connected, via a throttle line in the control piston, so that in the closed position of the control piston via the throttle line Pressure equalization in the two cylinder rooms. The opposite action of the control piston is thus canceled, which is therefore only by the spring is pressed against the glass break safety device in the opening direction.
- the invention is therefore based on the object of an extinguishing system with at least two spray heads of the type described at the beginning with simple constructional means to improve so that a simple control of at least one spray head from another spray head is possible.
- the invention solves the problem in that the spray heads one over the Control device openable drain line for the cylinder chamber for piston loading in the closing direction and a control piston spring-loaded in the closing direction have and that at least the control piston of a spray head via a depending on the position of the control piston of the other spray head Control line is controllable.
- the respective - Spray head can be operated via various control devices, because only this Drain line must be opened to reduce pressure in the associated Cylinder chamber with the result of ensuring that the control piston is pressurized with water on the opposite side because of the pressure drop is adjusted in the opening direction in the throttle line. Because with the drain line closed in the two cylinder rooms the same but in opposite directions on the Control piston builds up pressure and therefore the risk of accidental Adjustment of the control piston not supported by a control device in the opening direction there is, the load spring of the control piston must be in the closing direction act and an opening movement of the control piston when the drain line is closed prevent.
- Opening the drain line does not require the control device to be arranged to actuate the spray head on this itself, so that it becomes possible Fire detectors, for example a glass break protection regardless of the attachment to provide the spray head without proper operation of the Endanger spray head.
- the spray head can also be operated by two or several control devices that are only opening a drain line. This makes versatile control one Extinguishing system equipped with such spray heads possible because, for example Several spray heads can also be controlled via a control device.
- the drain line of the spray head to be controlled can a control device, for example a valve, can be opened.
- the control this control device required control line can be used as an electrical control signal line be formed, the one of the control piston of the controlling Spray head actuated switch is actuated when the control valve for the Drain line of the controlled spray head z. B. from an electromagnetic valve consists.
- the control line can also be through a hydraulic line Actuation of a valve adjustable via a piston are formed, whereby an application via the distribution chamber of the controlling spray head is recommended.
- control piston at least one spray head an additional piston surface for a piston action has in the direction of opening and that the associated cylinder space a hydraulic control line is connected, via which the control piston against the force of its load spring is opened.
- This control line can in turn the distribution chambers of adjacent spray heads are connected, so that at Actuation of a spray head the corresponding connected neighboring Spray heads are also operated, but with their own pressurized water supply. Therefore you only need control lines and no pressurized water supply lines additionally to be relocated, what the installation effort of this Extinguishing systems significantly simplified.
- control line can be provided with a suction valve, that with the piston adjustment a suction of water or air in the with the piston adjustment enlarging cylinder space allowed.
- the spray system shown has two spray heads 1a and 1b, one below the other are equally trained.
- Each of these spray heads 1a and 1b has a pressurized water connection 2 and a distribution chamber 3 provided with the pressurized water connection 2 is connected via a cylinder bore 4, which the distribution chamber 3rd interspersed and on the side facing away from the pressurized water connection 2 in one expanded cylinder space 5 opens.
- this cylinder bore 4 is a control piston 6 used, the overflow channels at its end facing the pressurized water connection 2 7 forms that from an adjustment of the control piston 6 from the drawn Closed position in an open position a pressure water passage from Allow pressurized water connection 2 to distribution chamber 3. From the distribution chamber 3 the pressurized water can then flow via distributor channels 8 to spray nozzles 9.
- the pressure connection 2 forms a cylinder chamber 10 for the control piston 6 Piston action in the opening direction.
- This cylinder space 10 is opposite Cylinder chamber 5 through a throttle line passing through the control piston 6 11 connected, the throttling effect by a corresponding throttle 12 is determined.
- About the throttle line 11 thus results in the closed Control piston 6 a pressure equalization in the cylinder chambers 10 and 5, so that after outside only the closing force of the loading spring 13 acts on the control piston 6, the itself on a screw-in base 14 penetrated by the control piston 6 for the cylinder space 5 supports. So that the control piston 6 from the drawn closed position into a passage that releases from the pressurized water connection 2 to the distribution chamber 3 Open position can be moved, it is necessary to adjust the pressure in the cylinder chamber 5 dismantle.
- At least one drain line 15 is provided, which can be opened by a control device 16. If one of the provided drain lines 15 opened via the associated control device 16, so the pressure in the cylinder chamber 5 drops, which with an axial adjustment of the Control piston 6 against the force of the load spring 13 due to the now one-sided Actuation is connected via the cylinder space 10. That is the way for the pressurized water to the spray nozzles 9 from the pressurized water connection 2 via the Distribution chamber 3 and the distribution channels 8 free.
- the control devices 16 can be constructed differently. According to the The illustrated embodiment is next to one held in a housing 17 Glass breakage protection 18 an electromagnetically actuated control valve 19 is provided, which, like the glass breakage protection device 18, blocks the associated drain line 15, as long as the control valve 19 is not opened or the glass break safety device 18 is not breaks what an opening of the control piston 6 in the manner described of its pressurized water. To function properly of the respective spray head 1a, 1b can also be checked by the control valve 19 can be opened by hand.
- the control piston 6 can have an additional piston surface 20 in a cylinder space 21, which is connected to a control line 22. Since the Control piston 6 are acted upon via this piston surface 20 in the opening direction can, the spray head can also be controlled via the control line 22 if the application pressure applied via the control line causes a piston displacement allowed against the load spring 13, because of the throttle line 11 results in a pressure medium compensation between the cylinder spaces 5 and 10.
- This Hydraulic control line 22 can, for example, with the distribution chamber 3 of the adjacent spray head 1b to be connected in response to this adjacent Spray head 1b a forced actuation of the connected Ensure spray head.
- the intended for this in the spray heads 1a and 1b from the distribution chamber 3 outgoing control line is in the embodiment 23 designated. If the control lines 23 and 22 are not used, their can Connections are closed with plugs.
- the cylinder space 21 would be a Prevent adjustment of the control piston 6 if not for an afterflow of the Pressure medium or for ventilation is provided.
- the Control line 22 connected to a suction valve 24, via which, if necessary Cylinder chamber 20 is ventilated. Since this suction valve 24 as a check valve acts, is the piston adjustment via the control line through this Nachsaugventil 22 not affected.
- the invention is of course not based on the illustrated embodiment limited.
- the solenoid valve 16 could also be via an electrical signal line are controlled via a by the control piston 6 of the spray head 1b actuated switch is applied, which in turn controls the control piston 6 of the spray head 1 a depending on the position of the control piston 6 of the spray head 1b allowed.
- the control line 23 can also be connected to such a control valve be connected.
