Fire extinguisher automatic valve tightening machine description: The difference between this equipment and the above equipment (CC-GF-SF)is that the equipment has increased a set of automatic oiling and pre-screwing functions. Oiling means that the lubricating oil is added to the mouth of the fire extinguisher bottle. The advantage of this is that the fire extinguisher valve is tightened more smoothly and the sealing is better. Pre-screwing means that two rollers fix the bottle body, and the motor drives the roller to rotate. When the bottle body rotates, the siphon is inserted into the bottle body, so that the staff can assemble this part more easily.
