Abstract: A safety valve coupled to a container to release liquid within the container. The container defines an opening surrounded by a container surface. The safety valve includes a housing defining an interior containing a fusible member for actuating a plug between a closed position and an open position to release the liquid upon melting the fusible member. A main body has a first end for coupling to the housing and a second end for coupling to the opening of the container. The main body second end includes a main body surface defining axial bores for receiving screws to fix the main body to the housing. Upon coupling the safety valve to the container, a small gap is formed between the container surface and the main body surface to limit loosening of the screws.

Abstract: An actuator comprises a valve case opened upward, a gas-driven actuator having a fixed portion provided on the valve case and fixed thereto and an operating portion movable upward and downward by a drive gas when the gas flows in or out, a valve stem extending upward from inside the valve case to above the case and having its upper end fixed to the operating portion of the actuator, and a valve element provided on the lower end of the valve stem. A valve case fluid seal bellows and an actuator gas seal bellows are connected between the valve stem and the actuator fixed portion and between the actuator fixed portion and operating portion, respectively. A vacuum is contained in a closed space formed by the valve stem, fluid seal bellows, actuator fixed portion, gas seal bellows and actuator operating portion. The variations in the internal pressure of the closed space due to variations in the ambient temperature are much smaller than the pressure of the drive gas, so that the flow rate of fluid remains unchanged by the variations in the ambient temperature.

Abstract: A safety valve device has a safety valve body configured to include a valve mechanism opened at a temperature of or over a preset reference temperature. The safety valve device also includes a gas flow path arranged to make a flow of hydrogen flowing out of a hydrogen tank via the safety valve body in a valve open position of the valve mechanism, and a discharge pipe configured to have a hydrogen discharge opening and arranged to discharge the hydrogen flowing through the gas flow path to the outside. The hydrogen discharge opening of the discharge pipe is formed to discharge the hydrogen in an oblique direction relative to a direction of an axial center of the gas flow path. The discharge pipe also has a groove formed to apply an input rotational force to the discharge pipe and thereby rotate the discharge pipe around the axial center of the gas flow path. In a typical application of a high-pressure gas tank with such a safety valve device mounted on a vehicle, this arrangement of the safety valve device enables the discharge direction of the high-pressure gas that is discharged from the safety valve device to be readily adjusted.
