Patent Searching and Data


Title:
規格結合金具から派生する機械式管継手
Document Type and Number:
Japanese Patent JP2008513687
Kind Code:
A
Abstract:
A coupling for joining pipe segments together is disclosed. The coupling is derived from a standard fitting and has a housing with a socket and an expanded region adjacent to the socket. Three shoulders are positioned within the expanded region. A sealing member and two support washers are positioned within the expanded region, each engaging a shoulder. A retainer is positioned in the expanded region between the two support washers. A lip, positioned at the end of the expanded region, extends radially inwardly and captures the sealing member, washers and retainer within the coupling. The retainer has a plurality of radial teeth angularly oriented to engage a pipe and prevent its removal from the coupling. One of the washers is kept in spaced relation from the other washer by a shoulder to prevent contact with the retainer upon assembly which may otherwise inhibit the teeth engaging the pipe.
