What are the precautions for using the fire hose interface?

The interface is the connection between the hose and the hose, fire pump, fire hydrant, and mobile water monitor. Mainly include hose interface, pipe thread interface, valve cover, internal thread fixed interface, external thread fixed interface, reducing interface, special-shaped interface, etc. The precautions in its use are:

① When using or storing, avoid falling, bumping and heavy pressure to prevent deformation and difficult assembly and disassembly.
②Before connecting, check the chute and sealing part carefully. If there is debris such as sludge and sand, it must be removed to avoid poor sealing and difficult assembly and disassembly.
③When connecting the inner buckle interface, insert the buckle claw into the chute and screw it in place in a clockwise direction. When connecting the hose, you need to straighten the hose and twist the hose so that the interface can be disconnected by itself.
④ When connecting the plug-in interface, insert it until you hear the sound of the spring pin of the female interface extending to the card slot of the male interface to ensure reliable connection.
⑤ Avoid contact with acid, alkaline and other chemicals during storage to prevent corrosion of metal parts and deterioration of rubber seals.
