Differential Pressure Sealing Device For Ball Valves

US Patent:
2012020, Aug 16, 2012
Filed:
Feb 7, 2012
Appl. No.:
13/367647
Inventors:
Arthur R. Yeary - Chicago IL, US
James P. Azzinaro - Hoschton GA, US
Hans D. Baumann - Rye NH, US
Assignee:
YEARY & ASSOCIATES, INC. - Chicago IL
International Classification:
F16K 5/06
F16K 25/00
US Classification:
251172, 251192, 251314
Abstract:
A differential pressure sealing device for use with ball valves that utilizes the pressure of the fluid being communicated in a piping system to increase the sealing force created by the sealing device. Fluid being communicated through a ball valve is provided to a sealing device that includes some type of element for creating a bias force. The pressure of the fluid being communicated increases the sealing pressure created by the sealing device. In this manner, the bias force created in the sealing device benefits from the pressure of the fluid being communicated to enhance the sealing when used with a ball valve or similar component.

Positive Shut-Off Seal

US Patent:
3986699, Oct 19, 1976
Filed:
May 20, 1975
Appl. No.:
5/579218
Inventors:
Joseph A. Wucik - Westerly RI
John E. Burdick - Stonington CT
James P. Azzinaro - Westerly RI
Assignee:
Posi-Seal International, Inc. - North Stonington CT
International Classification:
F16K 122
US Classification:
251173
Abstract:
A positive shut-off seal mechanism for use in pressurized fluid systems subject to high temperatures or fire risk. The seal mechanism includes a metallic valve seat in the form of an annular thin-walled skirt-like lip, preferably formed in a valve seat insert ring or retaining ring, the lip extending generally upstream toward the high pressure side of the valve. The edge of the lip engages a mating circumferential sealing surface of a valve disc, preferably at a location downstream from the plane of maximum disc diameter, with an interference fit to provide a preloaded radial sealing force between the edge of the lip and the sealing surface of the disc. The annular lip preferably forms the downstream side of an undercut groove for a resilient seal ring that provides a primary seal, the engagement of the lip edge with the sealing surface of the valve member providing a metal-to-metal backup seal in the event of damage to or destruction of the resilient seal ring. The valve disc material has preferably a coefficient of thermal expansion at least equal to that of the annular lip to maintain or increase sealing effectiveness with increasing temperature.
