Abstract

Provided is a valve locking device (200) which includes: a lower body (210) in which a first hole (213) through which a nut engagement portion (150) pierces is formed, and at one side of the lower portion of which a protruding piece (211) which protrudes vertically downwards is formed, and which restricts rotation of the operation lever (130) by the protruding piece (211) and the locking protrusion portion (113); an upper body (230) in which an accommodation groove (231) that accommodates the upper portion of the nut engagement portion (150) is formed and which is combined with the lower body (210); and a locker (220) which is provided so as to slidably move in the horizontal direction by a release unit (250) having a magnetic force between the lower body (210) and the upper body (230) wherein one end (A) of the locker (220) is inserted into the locking groove (153) of the nut engagement portion (150) when the upper portion of the nut engagement portion (150) is accommodated in the accommodation groove (231) of the upper body (230), with a result that the lower body (210) is not separated from the valve (100), and the one end (A) of the locker (220) having been inserted into the locking groove (153) of the nut engagement portion (150) is detached from the locking groove (153) when the locker (220) is slid in the horizontal direction by the release unit (250), with a result that the lower body (210) is separated from the valve (100).
