Abstract
Replaceable collector nozzle for a sliding gate. A pressure plate is provided with a collar or ring or other engaging element with interior securing connectors, and positioned beneath the sliding plate. The collector nozzle at its upper portion is provided with threads or other engaging connectors to engage the pressure plate connectors. Alternatively an interlock comprising cammed members interior of the ring or collar mate with corresponding members at the upper end of the replaceable collector nozzle when it rotatably engages the interior of the collar or ring. The collector nozzle can then be replaced during temporary shut off by twisting with a typical chain wrench and a new collector nozzle inserted without disturbing the mounted relationship of the remainder of the sliding gate and the top plate interiorly of the valve. In a further embodiment the coupling of the collector nozzle is a thrust-type which does not require rotation.
