ABSTRACT:
A substantially leak-free arrangement for isolating at least two fluid streams from each other and for conducting each fluid stream into a mixing zone is characterized in a first embodiment by a casing having substantially parallel upstream and downstream partitions, each partition being provided, for each fluid stream, with an orifice of a predetermined cross-section. Defined within the casing between the partitions is a valve chamber in which a valve plate, having a flow passage corresponding to each orifice in the partitions, is moveable from a first, closed, to a second, open, position. The valve plate in the first, closed, position prevents fluid communication between each of the orifices in the first partition and the corresponding orifices in the second partition. The orifices are arranged within the partitions so that, as the valve plate slidably moves from the closed to the open position, the orifices in the downstream partition are in fluid communication with the corresponding passages in the valve plate before those passages communicate with the orifices in the upstream partition. With the valve plate in the second, open, position, the passages in the valve plate register completely with the corresponding orifices in the first and second partitions to provide unobstructed flow paths for each fluid stream to a mixing region disposed downstream of the second partition. In a second embodiment of the invention, a first valve member and a second valve member cooperate to define a double valve arrangement for a single fluid flow, both valves being disposed upstream of a common mixing region. Both valves are operatively associated with an externally disposed, pivotally mounted actuator member. Movement of the actuator opens both the first and the second valves so as to introduce the fluid into the mixing region.
