Abstract

PURPOSE:To make the inadvertent panel opening or closing of a panel on-off type fluid tank preventable by installing a locking mechanism which interlocks a float to be displaced upon detecting the extent of level height and checks any motion of a fixture. CONSTITUTION:When level height in a fluid tank is reached to a fixed quantity, a float 14 detects the level height, producing its buoyancy, and it is displaced in the upper part, thereby having a sliding rod 13 slidden upward. And, this rod 13 makes a stopper 15 rotate clock wise, and an engaging part 15a of this stopper 15 is engaged with the front of a lever 8, so that it cannot release this lever 8 any longer. Consequently, an on-off panel 1a is in no case inadvertently opened or closed. On the other hand, when working fluid does not exist in the fluid tank or when the level height is not yet reached to a fixed quantity, the float 14 will not detect the level height, and the stopper 15 rotates counterclockwise, thereby moving the engaging part 15a, so that engagement between the lever 8 and the engaging part 15a is released, releasing the lever 8, thus the panel 1a can be opened.
