摘要: A valve includes a valve body with a hollow valve body interior and an opening-defining portion that defines an access opening. The opening-defining portion is arranged as a connection-facilitating structure for facilitating the fluid-tight connection of a separate isolation valve assembly to the opening-defining portion in a position over the access opening that enables removal and replacement of a valve-stopping mechanism from the valve through the isolation valve assembly. It may include a flange, exterior thread, one or more annular grooves or rings, and/or a segmented cam lock arrangement. The associated method includes (i) providing a valve-servicing assembly having an isolation valve assembly and an attached chamber-defining structure that defines a fluid-tight pressure chamber in which the valve-stopping mechanism fits, (ii) connecting the auxiliary valve assembly to the opening-defining portion of the valve body, and (iii) withdrawing the valve-stopping mechanism through the isolation valve assembly into the pressure chamber.

摘要: The tool of the invention is used to insert and secure a stopper plug to close a hole in the wall of a pipe carrying fluid under pressure. This permits removal of a defective pipe fitting such as a tee or a valve. The stopper plug includes a toggle or anchor for engaging the inner wall of the pipe at the location of the hole to be sealed shut. After the stopper plug is secured in place, the defective fitting is removed.

摘要: This invention relates to a pressure plug for sealing a service valve fitting aperture in a fully pressurized fluid transmission pipeline to enable service valve fittings to be replaced without interrupting the flow of fluid in the transmission pipeline.The plug, which is located below an elongated main shaft, is comprised of spaced apart cap members having a compressible or resilient material there-between and an inner shaft extending longitudinally through the central axis of the plug so that when a nut associated with the inner shaft and plug is tightened it expands the plug making it larger in diameter than the service valve fitting aperture in the pressurized pipeline. The fluid pressure forces it against the inner wall of the pipeline, thus sealing the aperture.
