Pressurized storage tank with automatic shut-down in case of leakage

摘要

A pressurized storage tank for toxic chemicals includes a shut-down valve assembly. Upon detection of a leak, the shut-down valve assembly stops the flow of chemicals from the outlet valves of the tank. The shut-down valve assembly is located within the pressure vessel of the tank for maximum safety. The outlet valves of the tank are external to the pressure vessel and are connected to the valve assembly. The shut-down valve assembly operates in a fail-safe manner, such that removal of power or control signals to the valve assembly results in the valves being closed.
