Abstract
An adjustable orifice in the steam supply line to a gelatinizer has a pair of facing flanges. An orifice plate between the flanges is adjusted with the orifice offset to the bore through the flanges so that the proper amount of steam is supplied to the gelatinizer. After proper adjustment, the plate is clamped in place and all portions of the plate extending beyond the flanges are cut off to prevent the flow rate from being changed by unauthorized personnel.
Claims4
A device for having a settable opening in a pipeline comprising:
- a. a pair of facing parallel flanges in the pipeline,
- b. bolts holding the flanges together,
