摘要：PURPOSE:To prevent the damage of a valve even if being ud under low pressure on a condary side for a long term by providing between a valve casing and a pressure nsitive plate the stopper which stops the movement of the said pressure nsitive plate just before a locking part provided on the tip side of a tubulous valve locks the valve casing. CONSTITUTION:A stopper 'S' is arranged so that, when a pressure nsitive plate 4 is moving toward a condary chamber 'y' side, just before a locking part 22 of a tubulous valve 2 knocks against the mouth edge of a fitting tube part 14, the stopper 'S' strikes against a knocking part 41 formed on a pressure fittings 40 fixed to the pressure nsitive plate 4 to check the movement of the pressure nsitive plate 4 toward the condary chamber 'y' side. Since the stopper 'S' locks the movement of the pressure nsitive plate 4 toward the condary chamber 'y', pressure applied between the valve 4b of a relief valve and its valve at 2b is caud only by a weak spring F2 for the relief valve.
