Abstract:
A sleeve valve comprising:a sleeve having an interior surface defining an internal fluid passage, the sleeve including an intake, a discharge nozzle section, and a clean-out section, the internal fluid passage extending downstream from the intake to at least the discharge nozzle section, the discharge nozzle section including a plurality of nozzles, the sleeve being adapted for fluid flow from the intake through the fluid passage and out the nozzles of the discharge nozzle, the clean-out section including at least one access port;a gate adapted for sliding within the sleeve in sliding sealing engagement with the interior surface of the sleeve between closed, throttling, open, and clean positions;the gate and sleeve being configured and adapted so that the gate, when in the closed position, prevents fluid within the fluid passage from flowing out the nozzles and the access port, the gate and sleeve being configured and adapted so that the gate, when in the throttling position, permits fluid within the fluid passage to flow out some of the nozzles but prevents fluid within the fluid passage from flowing out the access port of the clean-out section and others of the nozzles, the gate and sleeve being configured and adapted so that the gate, when in the open position, permits fluid within the fluid passage to flow out the nozzles but prevents fluid within the fluid passage from flowing out the access port of the clean-out section, the gate and sleeve being configured and adapted so that the gate, when in the clean position, permits fluid within the fluid passage to flow out the nozzles and out the access port, the clean-out section being adapted so that debris which is too large to fit through the nozzles of the discharge nozzle section may be removed via the access port of the clean-out section.
