The invention discloses a valve for opening and closing a flammable and explosive gas medium steel cylinder. The valve comprises an accommodating tube, wherein one side of the top of the accommodatingtube is provided with a knob; the bottom of the knob is provided with a connecting rod; the connecting rod penetrates through the accommodating tube; the bottom side wall of the connecting rod is provided with a connecting ring in a surrounding mode; and the bottom of the connecting rod is provided with a slide rod. According to the valve disclosed by the invention, the connecting rod is rotated,the connecting rod drives a transmission wheel to rotate, the transmission wheel drives a ring-shaped toothed belt to rotate, the ring-shaped toothed belt drives a drive gear ring to rotate, the drive gear ring drives a central rod to rotate through a driven gear ring, the central rod drives a wire ring to move, the wire ring extrudes a pressure spring, and gas inside the accommodating tube is discharged through a spiral channel among spiral plates; and the spiral plates rotate, so that the valve has the advantages of being capable of preventing other media from backfilling, reducing risk, assisting to rotate and saving labor.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a valve for opening and closing flammable and explosive gas medium cylinders. Background technique [0002] Valves are usually used as control switches to control the medium passing through the pipeline. Traditional valves are usually butterfly valves, ball valves, combination valves, lifting valves, etc. For some more dangerous media, the valve structure Especially important, related to the safety of construction and production use, most of the existing valves are made of plastics and various alloys. [0003] The traditional gas valve device is usually relatively simple, and it is difficult to prevent liquid or other media from entering the bottle during use. Once a dangerous accident occurs, the valve can only be actively closed to prevent the accident from spreading. Not only is the efficiency too low, but it is also very dangerous. It is inconvenient to operate, and the tradi...
