| 摘要 | PURPOSE:To prevent gas leak from a wet-type gas holder by installing, in the sealing groove,two high-resistance electrodes which are electrically connected so that the current value is varied by the variation of the water-level and detecting the water level in the sealing groove and driving and stopping a water supply pump, thus keeping the water-level always at the safe level. CONSTITUTION:A wet-type gas holder is equipped with gas tanks 2-1, 2-2, and 2-3 in a number of layers which are inverted in a water tank 1, and the connection part set between the upper and the lower layers is shut-off from the outside air by a sealing groove 3 and an in-water immersed plate 4. A water- level detector 5 constituted of two high-resistance electrodes 5-1 whose top edges are electrically connected so that the current value is varied by the variation of the water level is inserted into each sealing groove 3. Said detection signal is taken-out by a water-level setting apparatus 7, and the operation of a water supply pump 9 is automatically controlled in accordance with the elevation of the water level in the sealing groove 3. | ||||||
