Abstract
A packing seal characterized by a plurality of rings formed from extruded lineal members. The extruded lineal members each have a height h from top to bottom, a width .DELTA.R, a pair of heels that slope outwardly from the sidewalls of the top to near a substantially flat bottom, the bottom having a groove disposed intermediate the heels and adapted to receive a linear anti-roll tab from a contiguous ring therebeneath. The top lineal member has a substantially flat top without the anti-roll tab for being contiguous a gland ring. Dimensions of the respective dimensions, which are critical to operation of the seal at low pressure and high pressure, are disclosed and claimed; as are suitable mechanical pressure inducing mechanism and flow blocks that are employed to ensure and complete the seal.
Claims7
A seal sealingly engaged intermediate a cylindrically shaped rod and surrounding tubular, cylinder-shaped wall and including:
- a. a gland ring for retaining a top of said seal in place longitudinally:
- and
- b. means for supplying mechanical pressure to said seal, including a bottom ring:
- the improvement comprising:
- c. a top ring of packing seal consisting essentially of an extruded lineal member of elastomeric material having in cross-section a height h from top to bottom, a width .DELTA.R, a pair of heels that slope outwardly from said top to form a substantially flat bottom, said bottom having a groove disposed intermediate said heels and adapted to receive a linear anti-roll tab from a contiguous ring therebeneath;
- said lineal member having a substantially flat top contiguous said gland ring and having ends joined adjacent each other in a joint;
- said top ring serving both to block flow of fluid and to adapt a seal cavity to accommodate additional rings;
- and
- d. at least one additional ring of packing seal consisting essentially of an extruded lineal member of the elastomeric material having in cross-section height h from top to bottom, a width .DELTA.R, a pair of heels that slope outwardly from said sidewalls of said top to form substantially flat bottom, said bottom having a groove disposed intermediate said heels and adapted to receive a linear anti-roll tab from the contiguous ring therebeneath:
- said linear member having a substantially flat top for being contiguous said bottom of said contiguous ring at its top and having a linear anti-roll tab disposed on its top and placed laterally so as to matingly engage said groove on said bottom of said contiguous ring;
- the rings engaging tops to bottoms and tops of anti-roll tabs to bottoms of engaging grooves so as to form substantially cylindrical annular spaces radially interiorly and exteriorly of said anti-roll tab and within said grooves;
- said flat bottom of the bottom ring engaging said means for applying mechanical pressure;
- each said ring having its respective ends joined adjacent each other in respective joints.
