AIR OPERATED VALVE ADAPTER FOR MANUAL VALVE

摘要

PURPOSE: An air-driven valve adapter for a manual valve is provided to prevent the malfunction generating in the driving process of an air-driven valve device. CONSTITUTION: An air-driven valve adapter for a manual valve is arranged between a manual valve and an air-driven valve apparatus. The central axis of the manual valve is perpendicularly installed to elevate in a valve body(13). A rotation transfer shaft(14) cross-connected in the central axis is horizontally installed in the valve body. The air-driven valve apparatus supplies the rotation force to the manual valve to automatically open and close an inner gateway of a transfer pipe. An insertion groove is formed in the one-side of the body fixed and coupled in the rotation transfer shaft. A guide pin is formed in the other one-side of the body. A guide recess in which a lever is inserted is formed in the circumference of the body in order to compulsorily open and close the manual valve.
