Abstract:
1. A discharge/bypass valve adapted to be mounted to a vessel; said valve having a valve housing; an inlet; a discharge outlet formed by the bottom of the valve housing, and a bypass outlet; said valve inlet being defined by an inlet coupling and said bypass outlet being defined by an outlet coupling, said valve having a valve member between said inlet and by-pass outlet and which is movable between a discharge position in which a flowable dry product flowing into said valve is discharged through said discharge outlet and a by-pass position in which a flowable dry product passes through said valve from said inlet coupling to said outlet coupling; wherein, when said valve member is in said by-pass position there is a continuous fluid-tight path between said valve inlet and said valve bypass outlet; and when said valve member is in said discharge position, said valve inlet is in communication with the atmosphere, such that the pressure of fluid within said valve inlet is dissipated; wherein said valve member is a sleeve generally coaxial with said inlet and outlet coupling tubes, wherein, when said sleeve is in said discharge position, a discharge space is defined between an outlet of said sleeve and one of said inlet and outlet couplings and which is in communication with said discharge outlet of said valve, and when said sleeve is in said bypass position, said sleeve connects said inlet and outlet couplings such that said discharge outlet is bypassed, wherein said sleeve is within said valve housing in said discharge position and said by-pass position.
