Abstract
An eccentric rotary valve housing is provided which can be used in a flangeless construction or a flanged construction. In the flangeless construction, a stud block is recessed to pass around the offset neck portion and is of a size to resist bending and torsion stresses equal to those in the tie bolts. In the flanged construction, a pair of rings are keyed on the housing to cooperate with flanged pipes.
Claims7
In combination,
- a housing for an eccentric rotary control valve, said housing having a cylindrical body part disposed on a longitudinal axis and a neck part disposed on an axis extending in radially offset relation from said longitudinal axis of said cylindrical body part;
- a pair of flanges disposed about opposite ends of said cylindrical body part, each said flange having equi-spaced apertures therein;
- a plurality of draw bolts extending coaxially of said cylindrical body part and through at least some of said apertures in said flanges to secure said flanges together;
- a stud block disposed perpendicularly between said flanges in alignment with a pair of coaxial apertures in said flanges, said block being disposed between one of said draw bolts and said neck part and having a recess partially encompassing said neck part;
- and
- a pair of cap screws, each cap screw passing through a respective flange aperture into coaxial threaded engagement with said stud block, said cap screws and said draw bolts being disposed at equal spacings about said flanges.
