Hose accessories mainly refer to the accessories necessary to connect and use fire hoses, including interfaces, water distributors, etc.
1. interface
The connection is the connection between the hose and the hose, fire pump, fire hydrant or mobile water monitor. There are mainly hose joints, pipe thread joints, valve covers, internal thread fixed joints, external thread fixed joints, different diameter joints, special-shaped joints, etc.
Pay attention when using:
(1) When using and storing, avoid falling, bumping and heavy pressure to prevent deformation and make assembly and disassembly difficult.
(2) Before connecting, check the chute and the sealing part carefully. If there is any debris such as sludge and sand, it must be removed in time to prevent difficult assembly and disassembly and poor sealing.
(3) When connecting the inner buckle interface, insert the buckle claw into the chute and then screw it clockwise. When connecting the water belt, it is also necessary to straighten the water belt so that the waterproof belt is twisted and the interface is disengaged by itself.
(4) When connecting the plug-in interface, it should be inserted until the sound of the spring pin of the female interface extending to the slot of the male interface is heard, so as to ensure a reliable connection.
(5) Be careful to avoid contact with chemicals such as acids and alkalis during storage to prevent corrosion of metal parts and deterioration of rubber seals.
2. Trap
The water separator is a connecting device that divides the water flow of the outlet line into the water flow of the branch line. According to the number of branches divided, there are two points of water, three points of water and four points of water.
(1) Structure
Each water distributor has a water inlet and several water outlets, which can be used at the same time or separately, and the interfaces are all buckled inside. The water outlets are equipped with stop valves or ball valves, which can be closed at any time to control the water flow and facilitate the addition and replacement of branch hoses.
(2) Use and maintenance
Before use, check whether the interface sealing ring and valve are complete and easy to use. Try to keep warm in severe winter to prevent freezing failure. Rinse with clean water after use.
