THE GLOBE VALVE HAVING DUPLEX BLOCK STRUCTURE WITH I-TYPE DISK

摘要

The present invention relates to a technique related to a globe valve having a double blocking structure using an I-type disk, improving a structure of a disk to be closely attached to a sheet inside the globe valve to improve airtightness and constantly controlling a discharge amount of fluid by processing an edge of the disk to be tilted. An engraved groove having a smaller diameter than a diameter of a pore formed on the sheet is formed on the outer circumferential surface of the disk, and a corner of the edge of an end of the disk is curved or is cut to have a slope.
