| 摘要 | PURPOSE:To prevent the leakage of stored gas above the piston by providing multiple groove-like cutouts which are arranged in an end of a holder side plate in the vertical direction and are open to the periphery of the end of the side plate, and by welding each cutout to a column so as to integrally connect the column and side plate. CONSTITUTION:An end of a side plate of a piston type gas holder has horizontal cutouts 13 which are arranged vartically with a uniform spacing and are open to the side periphery. The side plate 12 and a column 11 are connected by rivets 7 and welding metal 8, and are also connected by welding the cutouts 13 of the side plate 12 to the column 11. Therefore, the connecting tightness between the column 11 and side plate 12 is improved to enhance the connecting strength. As the gap between the mating surfaces of the column 11 and side plate 12 is interrupted at a uniform interval in the vertical direction, the gas stored in the holder under the piston is prevented from leaking above the piston. | ||||||
