摘要： The present inventive concept relates to a method of manufacturing a pipe packing inserted into a housing having a hollow body shape to prevent fluid flowing inside a pipe from leaking to the outside, the method including: manufacturing the pipe packing by injecting molten rubber into a mold assembly having an outer mold and an inner mold, wherein the pipe packing is configured as a hollow body and comprises an outer circumferential part located outside of the pipe relative thereto, opposite surfaces provided in directions toward a middle of the pipe packing at opposite ends of the outer circumferential part, and an inner circumferential part provided toward a center portion of the opposite surfaces therefrom, wherein the inner circumferential part has a gap provided therein to be divided into opposite inner circumferential parts.

摘要： A self-sealing fill nipple for a pressure regulator having a fill port, includes a body having a first end having a quick connect fitting, a mid-body region and a threaded region for threadedly engaging the pressure regulator at the fill port. The threaded region extends from about an end of the body toward the mid-body region and is spaced therefrom by a gap. The threaded region has crest and root diameters. The mid-body region includes a tightening element proximal the quick connect fitting and a gap between the tightening element and the threaded region. The gap has a diameter equal to or less than the threaded region root diameter. A combination of a pressure regulator and a self-sealing fill nipple are also disclosed.

摘要： A method of borehole pipe installation begins with unfinished stick pipes brought to the installation site and then machined or cut to form male and female ends. The pipe ends are then locked together to form a flush joint. The lock can be provided via a groove cut into one of the ends for receipt of a lock gasket, which secures and seals the joint when the pipes are pushed together, and prevents the pipes from being pulled apart. Alternatively, to the groove and lock gasket, the ends can be glued and screwed together, with the screws allowing the joined pipes to be pulled through the borehole before the glue is dry. The pipe joint has flush exterior and interior surfaces to minimize borehole clearance and maximize fluid flow through the pipe assembly.

摘要： A pre-assembled pipe coupling includes a gasket, a housing surrounding the gasket, and a fastener. The housing has three segments sequentially coupled to each other to define an insertion boundary. A bridge segment has a first mount extending lateral from the wall and having a plurality of first lateral walls defining a first aperture and a second mount having a plurality of second lateral walls defining a second aperture. A first clamp segment has a first hook disposed in the first aperture. A second clamp segment has a second hook disposed in the second aperture. The fastener is disposed through the first fastener aperture and the second fastener aperture. The fastener has an adjusted length at which the first clamp segment grips the gasket, and the second clamp segment grips the gasket to locate the first sealing lip and the second sealing lip within the insertion boundary.

摘要： Spigot device including a spigot formed with exterior gripping teeth and sleeve device to telescope over the spigot. The sleeve device is formed with a radially inwardly opening, distally contracting conical bearing surface which mounts a radially inwardly contractible gripper ring device captive therein, and constructed to be driven radially inwardly by the bearing surface as the sleeve is drawn proximally on the spigot to grip a plastic pipe trapped in the annulus between the sleeve and spigot.

摘要： A pre-assembled pipe coupling (11) includes a gasket (200), a housing (12) surrounding the gasket, and a fastener (20). The housing has three segments sequentially coupled to each other to define an insertion boundary. A first segment (12c) includes a first mount (18) extending lateral in a first direction from the wall and having a plurality of first lateral walls that define a first aperture (22), and a second mount (18) extending laterally in a second direction from the wall, the second mount having a plurality of second lateral walls that define a second aperture (22). A second segment (12a) includes a first hook (14) disposed in the first aperture and a first tab (16) defining a first fastener aperture. A third segment (12b) includes a second hook (14) disposed in the second aperture and a second tab (16) defining a second fastener aperture. The fastener is disposed through the first fastener aperture and the second fastener aperture.
