Abstract
A flange is provided for a valve which extends in a radial direction outwardly from the valve and has a peripheral edge. The peripheral edge is comprised of a series of outer surfaces positioned at or beyond a first radial distance from a center point of the valve, and may be in the form of tabs, and an alternating series of inner surfaces positioned at or within a second radial distance from the valve or flange center point, as intervening portions. At least one of the outer surfaces and inner surfaces may be sized and arranged to supportingly engage a plurality of series of connecting bolts which extend perpendicular to the radial direction, wherein the plurality of series of connecting bolts are arranged on bolt circles of different diameters relative to the valve.
Claims20
A flange for a check valve extending in a radial direction outwardly from said check valve and having a peripheral edge;
- said peripheral edge comprising a plurality of alternating tabs and intervening portions wherein said tabs extend radially further outwardly than said intervening portions.
A generally circular flange for a valve extending in a radial direction outwardly from a center point of said flange and having a peripheral edge, said peripheral edge comprising a series of outer surfaces positioned at or beyond a first radial distance from said center point and an alternating series of inner surfaces positioned at or within a second radial distance from said center point, and connecting surfaces extending between said outer surfaces and said inner surfaces.
A valve comprising:
- a valve body adapted to be received in a pipeline, a flange having a peripheral edge extending from said valve body radially in comparison to a longitudinal axis of said pipeline;
- said peripheral edge comprising a series of outer surfaces positioned at or beyond a first radial distance from said valve body and an alternating series of inner surfaces positioned at or within a second, smaller radial distance from said valve body.
