Abstract

The invention relates to an alarm valve station (1), in particular a wet alarm valve station, of a fire extinguishing system (100), having an alarm valve (3) with an extinguishing fluid inlet (5) and an extinguishing fluid outlet (7), wherein the alarm valve (3) has a closing body that can be moved back and forth between a blocking state and a release state, wherein the fluid inlet chamber and the fluid outlet chamber are separated from one another in the blocking state and communicate with one another fluidically in the release state, an alarm triggering device (9) for triggering a fire alarm, which is connected with the alarm valve (3), and a delay container (11a, 11b) in order to delay triggering of the fire alarm, wherein the alarm valve (3) is fluidically connected with a fluid inlet (13) of the delay container, and a fluid outlet (15a-15c) of the delay container (11a, 11b) is fluidically connected with the alarm triggering device (9). The invention proposes that the delay container (11a, 11b) have several fluid inlets (13) and/or several fluid outlets (15a-15c).

First claim

The invention claimed is:

1. An alarm valve station of a fire extinguishing system, comprising:
an alarm valve with an extinguishing fluid inlet and an extinguishing fluid outlet, wherein the alarm valve has a closing body that can be moved back and forth between a blocking state and a release state, wherein a fluid inlet chamber and a fluid outlet chamber are separated from one another in the blocking state and communicate with one another fluidically in the release state,
an alarm triggering device for triggering a fire alarm, which is connected with the alarm valve,
and a delay container in order to delay triggering of the fire alarm, wherein the alarm valve is fluidically connected with a fluid inlet of the delay container, and a fluid outlet of the delay container is fluidically connected with the alarm triggering device,
wherein the delay container has a chamber centered in the delay container and a central longitudinal axis that extends from a first side to a second opposing side along the chamber, the first side having several fluid outlets, the second side having at least one fluid inlet, and
wherein the at least one fluid inlet and/or the several fluid outlets comprises a central axis parallel to and spaced apart from the longitudinal axis.

2. The alarm valve station according to claim 1 , wherein the several fluid outlets are connected with the alarm triggering device or several respective alarm triggering devices.

3. The alarm valve station according to claim 1 , wherein the at least one fluid inlet on the second side of the delay container is not aligned flush with any of the several fluid outlets on the first side of the delay container.

4. The alarm valve station according to claim 1 , wherein the delay container has a multipart design.

5. The alarm valve station according to claim 1 , wherein the delay container has a first container part and a second container part that are detachable.

6. The alarm valve station according to claim 5 , wherein the first container part and second container part each have a flange section, wherein the flange sections of the first container part and second container part are designed to be mutually connected.

7. The alarm valve station according to claim 5 , wherein the first container part and second container part are identical.

8. The alarm valve station according to claim 5 , wherein the first container part is connectable to the second container part at various rotational angle positions.

9. The alarm valve station according to claim 5 , wherein a gasket element is arranged between the first container part and second container part, which protrudes into the chamber of the delay container.

10. The alarm valve station according to claim 9 , wherein the gasket element protrudes into the chamber of the delay container in such a way that the central axis of the at least one fluid inlet intersects the gasket element.

11. The alarm valve station according to claim 1 , wherein the at least one fluid inlet of the delay container is aligned flush with at least one of the several fluid outlets of the delay container.

12. A fire extinguishing system, having
an alarm valve station according to claim 1 ,
an extinguishing fluid supply that is fluidically connected with the extinguishing fluid inlet of the alarm valve, and
a sprinkler arrangement that is fluidically connected with the extinguishing fluid outlet of the alarm valve.

13. An alarm valve station of a fire extinguishing system, comprising:
an alarm valve with an extinguishing fluid inlet and an extinguishing fluid outlet, wherein the alarm valve has a closing body that can be moved back and forth between a blocking state and a release state, wherein a fluid inlet chamber and a fluid outlet chamber are separated from one another in the blocking state and communicate with one another fluidically in the release state,
an alarm triggering device for triggering a fire alarm, which is connected with the alarm valve, and
a delay container upstream of the alarm triggering device in order to delay triggering of the fire alarm,
wherein the delay container has a first container part connectable to a second container part at a plurality of rotational angle positions,
wherein the first container part includes several fluid outlets, at least one of the several fluid outlets fluidically connected with the alarm triggering device, and
wherein the second container part includes at least one fluid inlet fluidically connected to the alarm valve.

14. The alarm valve station according to claim 13 , wherein the several fluid outlets of the delay container are connected with the alarm triggering device or several respective alarm triggering devices.

15. The alarm valve station according to claim 13 , wherein the at least one fluid inlet is not aligned flush with any of the several fluid outlets.

16. The alarm valve station according to claim 13 , wherein the delay container has a longitudinal axis that extends from a first side to a second side of the delay container, and the at least one fluid inlet and/or at least one of the several or all of the several fluid outlets are spaced apart from the longitudinal axis.

17. The alarm valve station according to claim 13 , wherein the first container part and the second container part are detachable.

18. The alarm valve station according to claim 17 , wherein the first container part and second container part each have a flange section, wherein the flange sections of the first container part and second container part are designed to be mutually connected.

19. The alarm valve station according to claim 18 , wherein the first container part and second container part are identical.

20. The alarm valve station according to claim 19 , wherein a gasket element is arranged between the first container part and second container part, wherein the at least one fluid inlet has a central axis, and wherein the gasket element protrudes into an interior of the delay container in such a way that the central axis of the at least one fluid inlet intersects the gasket element.

21. The alarm valve station according to claim 13 , wherein the at least one fluid inlet is aligned flush with at least one of the several fluid outlets.

22. A fire extinguishing system, having
an alarm valve station according to claim 13 ,
an extinguishing fluid supply that is fluidically connected with the extinguishing fluid inlet of the alarm valve, and
a sprinkler arrangement that is fluidically connected with the extinguishing fluid outlet of the alarm valve.
