Abrégé

The purpose of the present invention is to provide a line blind valve which can reduce the weight of a blind and the time required to open and block a pipe line and can fundamentally block a dead space by interchangeably using an opening blind and a blocking blind during the opening and closing of the pipe line, and which can implement a valve body which is simple to design and is compact by assigning the air-tightness performance to only the blinds and a structure for fixing the blinds. To this end, provided is a valve installed between pipes so as to open or block a pipe line, the valve comprising: a valve body having opening portions formed at the front and rear sides thereof; a front sheet formed toward the inside of the valve body in the opening portion of the front side, and a rear sheet formed toward the inside of the valve body in the opening portion of the rear side; an opening blind installed during the opening of the pipe line and a blocking blind installed during the blocking of the pipe line, the blinds being inserted between the front sheet and the rear sheet; and a gear unit which is coupled by a screw with the rear sheet and thus when moving forward, pressurizes the opening blind or the blocking blind toward the front sheet side and thus airtightly fixes the blind.
