Description

Technical field:

[0001] The utility model relates to the technical field of fire protection systems, in particular to an automatic sprinkler fire extinguishing system. Background technology:

[0002] Architecture is a microcosm of culture. The diversity of architecture is not only reflected in the appearance of the building, but also in the volume of the building. On the basis of limited land, there are more and more large-scale buildings. The problem that comes with it is the fire protection of the building. At present, the commonly used fire water systems are fire hydrants, automatic sprinkler fire extinguishing systems, etc.

[0003] For the automatic sprinkler fire extinguishing system, it is composed of a fire pump, a fire pool, a pipeline, an alarm valve group, a closed sprinkler nozzle, etc. Among them, the alarm valve group is the core component of the sprinkler system and needs to be separately installed in the alarm valve room. Drainage facilities need to be installed in the alarm valve room. At present, the conventional drainage facilities in the alarm valve room are floor drain + sump, drainage ditch + sump or a separate sump. For this method, under non-firefighting conditions, the function of the alarm valve needs to be tested regularly. Generally, a DN25 water discharge test valve is set at the alarm valve, which is installed about 1.0 meters from the ground. When testing the drainage, the drainage needs to be discharged to the floor drain or drainage ditch through the ground slope. The water discharge test valve has a large drainage volume, which causes a lot of water on the ground and makes the ground unclean. Utility model content:

[0004] The utility model aims to provide an automatic sprinkler fire extinguishing system which can collect test water and drainage and can also keep the ground between alarm valves clean.

By collecting the test water and drainage at the end of each alarm valve group, it is indirectly discharged to the floor drain or drainage ditch or water collection pit, which can not only receive a large amount of test water and drainage, but also keep the ground between the alarm valves clean.

[0006] Furthermore, the drainage pipe includes a horizontal section and a vertical section, the outlet end of the horizontal section is connected to the inlet end of the vertical section, and the outlet end of the vertical section is connected to a floor drain or a drainage ditch; the water collection port is arranged in the horizontal section and is correspondingly located directly below the water discharge test valve. The drainage pipe is arranged in horizontal and vertical sections, so that the pipeline layout in the alarm valve room is neat and beautiful.

[0007] Furthermore, the alarm valve group also includes a signal butterfly valve, a wet alarm valve, a filter, a delay device, and a hydraulic alarm. The water supply pipe connecting the water outlet of the fire water pump and the water inlet of the sprinkler network is provided with a wet alarm valve and a signal butterfly valve in sequence. The water supply pipe connecting the wet alarm valve and the signal butterfly valve is connected with a shunt pipe, and the water inlet end of the shunt pipe is connected to the water supply pipe; the shunt pipe is provided with a filter, a water discharge test valve and a delay device in sequence from the water inlet end to the end; the delay device is arranged at the end of the shunt pipe, and the delay device is connected to the hydraulic alarm.

[0008] Advantages of the utility model:

[0009] The utility model adds drainage pipes and water collection ports in the alarm valve room to collect the test water drainage at the end of each alarm valve group and discharge it indirectly to the floor drain or drainage ditch or water collection pit. In this way, a large amount of test water drainage can be received and the floor of the alarm valve room can be kept clean. Description of the drawings:
