Can fire monitors share a pipeline network with fire hydrants
In the field of building fire protection, the question of whether the fire hydrant system pipeline can be shared with other systems is of great significance. The answer is that under certain conditions, it can be shared, but it must comply with relevant normative requirements.
1. Sharing with the automatic sprinkler system
Permitted to share: The indoor fire hydrant water supply pipeline and the automatic sprinkler system pipeline can be combined under certain conditions.
Normative requirements
When they are combined, the water supply pipeline should be separated before the alarm valve in the direction of water flow.
The system design water quantity, water pressure, and one-time fire extinguishing water quantity should meet the requirements of the larger of the two systems in terms of design water quantity, water pressure, and one-time fire extinguishing water quantity.
It should meet the other design requirements of the two systems at the same time and be able to operate independently without affecting each other.
2. Sharing with the fire monitor system
Permitted to share: The fire monitor system and the fire hydrant system can share pipelines under certain conditions.
Normative requirements
The system design water quantity, water pressure, and one-time fire extinguishing water quantity should meet the requirements of the larger of the two systems in terms of design water quantity, water pressure, and one-time fire extinguishing water quantity.
It should meet the other design requirements of the two systems at the same time and be able to operate independently without affecting each other.
3. Other precautions
Prevent backflow: When the indoor fire water supply system is directly supplied by the domestic and production water supply system pipeline network, measures to prevent backflow should be taken at the introduction pipe.
Shared water pumps: The automatic sprinkler system and the fire hydrant system can share fire pumps, but they must meet the requirements of the and cannot affect the fire extinguishing function of each other's system.
When the fire hydrant system pipeline is shared with other systems, it must meet relevant normative requirements to ensure the fire water quantity and pressure, as well as the independence and reliability of the system. In practical engineering, design should be carried out according to specific conditions and relevant norms should be strictly followed.
