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 exists between the seal ring and the seal carrier and a secondary leak path may exists between the seal carrier and the valve body. A first and second auxiliary seal may prevent fluid flow through the primary and secondary leak path, respectively.

摘要： An improved laundry appliance is provided wherein the door is mounted to a shroud, separate from the front and top panels of the cabinet. Therefore, during manufacturing assembly or repair work, the door can be shut and the operation of the appliance tested with the front and top panels removed from the appliance. After the operational testing is completed, the front and top panels can be installed to the remaining cabinet panels.
