摘要： A seal assembly is provided for a rotary ball valve having a top-mounted bonnet, thereby allowing the seal assembly to be installed and removed without removing the valve from the pipeline. In an embodiment, the seal assembly may include a seal ring disposed within the valve interior and biased toward the ball element of the valve. A seal carrier may be disposed between the seal ring and the valve body, and the seal carrier may be removably secured to the valve body by a plurality of bolts disposed in the valve interior. A primary leak path may exist between the seal ring and the seal carrier and a secondary leak path may exist between the seal carrier and the valve body. A bellows seal may prevent fluid flow through the primary leak path, and an auxiliary seal may prevent fluid flow through the secondary leak path.

摘要： A valve body includes first and second openings, a gallery, and first and second flow conduit portions. The openings are centered on a central axis of the valve body. The gallery is disposed between the openings and includes a cylindrical space on a gallery axis that is perpendicular to the central axis. The first flow conduit portion extends between the first opening and a side opening of the gallery. The second flow conduit portion extends between the second opening and a bottom opening of the gallery. The second flow conduit portion includes a straight cylindrical conduit section in communication with and extending away from the bottom opening of the gallery. The straight cylindrical conduit section has a diameter that is equal to or less than a diameter of the bottom opening of the gallery to facilitate fluid flow through the valve body.
