Description

Technical Field

[0001] The utility model belongs to the technical field of ship fire extinguishing spraying, and in particular relates to a ship ammunition compartment water spraying system. Background Art

[0002] The ship fire sprinkler system is a fire control system used on ships. It uses sprinklers to spray water or fire extinguishing agents to control and extinguish fires. When a fire occurs, the system is activated, and the sprinkler releases pressure to spray water or fire extinguishing agents through the nozzles, forming a spray atomization effect, rapidly reducing the temperature around the fire source, achieving the purpose of controlling and extinguishing the fire.

[0003] The Chinese patent with application number CN201821500924.8 specifically relates to a ship cabin sprinkler system, including a sprinkler nozzle, a pressure water tank, a fresh water tank, a fire alarm device, a water pump control box and a controller. The sprinkler nozzles are distributed in various areas of the cabin, and the outlet of the fresh water tank is divided into two routes. The first route is connected to the first safety signal butterfly valve and the first water flow indicator. A first wet alarm valve and a first automatic exhaust valve are also provided between the first safety signal butterfly valve and the first water flow indicator. The outlet of the first water flow indicator is connected to the sprinkler nozzle and the first terminal water testing device. The second route is the same as the first route. The outlet of the water pump control box is connected to the sprinkler pump. The outlet of the pressure water tank and the outlet of the sprinkler pump are both connected to the first safety signal butterfly valve and the second safety signal butterfly valve through pipes. The fire alarm device is connected to the water pump control box. The fire alarm device includes a fire alarm host, a fire display panel and fire alarms distributed in various areas of the cabin. The controller is connected to the water pump control box.

[0004] In the ammunition hold of a ship, it is necessary to keep the cabin dry at all times to prevent items from being damaged by moisture. The design of the various valves in the fire extinguishing system is prone to water leakage, resulting in losses. At the same time, improving safety through system design is also an important part of fire extinguishing in the ammunition hold. Utility Model Content
