Summary: | The utility model discloses a chemical engineering environment-friendly pneumatic isolating valve, and belongs to the technical field of valves. The isolating valve comprises a valve body, valve bases, valve plates, centering bearings, valve shafts and an inflation opening. The number of the valve bases, the number of the valve plates, the number of the centering bearings and the number of the valve shafts are respectively two. The valve shafts are disposed on the valve body, and the valve shafts are provided with the centering bearings respectively. The valve plates are fixed to one side of the valve body through the valve bases. A four-bar mechanism is adopted between the driving ends of the valve shafts, and the valve plates are driven by the four-bar mechanism. The inflation opening is formed between the valve bases. The chemical engineering environment-friendly pneumatic isolating valve achieves pneumatic isolating sealing and is good in sealing performance, high in safety and reliability, easy to operat |
