The distance between fire pump joints should not be less than 20 m to ensure the parking of fire fighting vehicles and to meet the needs of the turning radius of fire engines. The fire pump splicer should be connected to the indoor ring network, in the connected pipe sections should be set fire extinguisher valve check valve, safety valve, gate valve and drain valve. Fire extinguisher valve check valve is used to prevent the indoor fire supply network water backflow to the outdoors.
