Maintenance and management of wet sprinkler system

The ultimate goal of strengthening the maintenance and management of the wet sprinkler system is to achieve its two basic functional requirements. One is to automatically sprinkle fire after a fire occurs; the other is to send out an alarm while sprinkling water.

Equipment requirements

(1) Requirements for fire-fighting water sources.Fire-fighting water source is the foundation of sprinkler system. If the water source fails to meet the requirements, the best equipment is useless.Therefore, enterprises and institutions should always check the situation of the fire tank to ensure that the water level meets the requirements and that the fire water is not used by other parties and the water replenishment facilities are normal; The facilities to ensure that the water level of the fire fighting water tank and the fire fighting water are not used by other parties should be normal; The check valve on the outlet pipe of the fire water tank should be closed tightly; after the fire water pump is started, check whether the water level of the fire water tank rises.

(2) The opening and closing requirements of relevant valves.The fire valve is like a safety door, and the valve opening and closing does not meet the requirements, which will cause the fire extinguishing to not be carried out smoothly.In the daily inspection of the wet sprinkler system, it is necessary to ensure that the inlet and outlet valves of each fire pump, the inlet and outlet valves of the stabilized pump, the main water source valve, the control valve of the alarm valve group, the control valve of the water pump adapter, and the water flow The indicator signal valve, etc. are in the normally open state to ensure that the system can automatically start and ensure continuous water supply in the event of a fire.

3) Water pump adapter.There should be a sign indicating the system and area to which it belongs;Flexible opening and closing of control valve and drain valve;Check valve installation direction should be correct;The check valve should be tightly closed

(4) Requirements for wet alarm valve group。Indicate the name of the system and the protected area,The pressure gauge display should meet the set value,The control valve should be fully opened, and the handwheel should be fixed with a lock,The opening and closing signs should be obvious,When using a signal valve, the feedback signal should be correct,Components such as alarm valves should be sensitive and reliable,Open the test valve, and the pressure switch action should feed back a signal to the fire control equipment.
