BI-DIRECTIONAL SEAL ASSEMBLY FOR USE WITH VALVES |
摘要 |
Seal assemblies for use with fluid valves are described. An example seal assembly (502) includes a first seal (508) and a second seal (510) opposite the first seal. The first and second seals are to sealingly engage a closure member (504) of a valve and a sealing surface (314) opposite the closure member. A spacer ring (512) is disposed between the first and second seals to prevent the first and second seals from contacting each other. The spacer ring has an aperture (514) therethrough to enable pressurized fluid to flow from a first side of the spacer ring and a second side of the spacer ring opposite the first side. |
