The connection between the plastic-coated PVC lay flat hose and the drum should ensure the surroundings of the plastic-coated PVC lay flat hose, and the connection close to the plastic-coated PVC lay flat hose is somewhat uneven.
The one-time application of plastic-coated PVC lay flat hose reel should be equipped with an insurance mechanism to ensure that the import valve is not opened and the hose can not start, but it should also be noted that the hose reel should have a residual fire extinguishing agent in the channel.
The opening and closing direction of the inlet valve should be clearly marked. Pay attention to clockwise closure, and some arms rotating around the fixed axis can swing horizontally outward. The swing viewpoint should not be less than 90 degrees.
