Locking pipe joint assembly, device and method

摘要

A locking pipe joint assembly, device and method can employ a center body connector, one or more sealing elements, such as a wiper seal and a sealing ring, a sealing ring retainer and a retaining cap. In various embodiments, primary and secondary fastening rings are employed along with a retaining cap sleeve. In embodiments, the retaining cap includes an internal or external thread that mates with an external or internal thread on one side of the center body connector, which allows the retaining cap to tighten the packing arrangement components around an inserted piping or tubing element, and in secure engagement with the interior of the center body connector. In embodiments, a bolt element is provided for further securing of the retaining cap to the center body connector.

主权项

1. A locking pipe joint assembly, comprising:
a center body connector having an outer surface, an axial end wall surface, and an interior surface forming a cavity extending through the body connector along a center body connector axis, the center body connector including a flange formed so as to extend radially inwardly from the interior wall surface and a block extending radially outwardly from the outer surface, wherein the block is formed with at least one opening having an inner surface; a retaining cap having a radially extending wall and an axially extending wall, with each of the radially extending and axially extending walls having respective inner and outer surfaces, with a bolt retaining block formed with and extending radially outwardly from the axially extending wall outer surface, with the bolt retaining block forming a bolt retaining cavity, wherein the retaining cap axially extending wall inner surface forms a cavity extending through the retaining cap along a retaining cap axis, wherein the retaining cap axially extending wall is adapted to threadedly engage the center body connector such that the center body connector axis and the retaining cap axis are coaxial; and a first packing arrangement engaged with the retaining cap inner surface and the body connector interior surface, whereupon as the retaining cap threadedly engages the center body connector, the first packing arrangement is compressed, wherein the first packing arrangement comprises at least one sealing member and a sealing ring retainer, wherein the sealing ring retainer has an axially outer surface having a support ridge positioned radially inwardly of a tip, wherein the axially outer surface includes a lower edge surface extending axially inwardly and radially inwardly from the tip, and further includes an upper edge surface extending axially inwardly and radially outwardly from the support ridge such that the upper edge surface meets the lower edge surface at a notch.
