Abstract
A structure of a pipeline connector is mainly composed of a socket, a restriction ring, a cover ring, a fixed inner pipe, a fixed outer pipe and a stopping ring. The socket is composed of a cone shaped opening and secured with an inner pipe. The opening of the socket comprises a restriction ring and a locknut, with the fixed inner pipe secured within the socket by means of the locknut, the fixed inner pipe and the inner pipe of the fixed inner pipe been inserted through the fixed outer pipe and sleeved with a stopping ring at the end of the inner pipe so as to allow a smooth sliding of the fixed inner pipe and the fixed outer pipe, relatively.
Claims4
A pipeline connector comprising:
- a coupling body having threads formed on one longitudinal end thereof and an inner pipe extending from an opposing longitudinal end, said coupling body having a first bore extending between said opposing longitudinal ends, said inner pipe having a second bore extending longitudinally therethrough and in fluid communication with said first bore, said inner pipe having a pair of stoppers formed on a distal end thereof;
- a socket member having threads formed on one end thereof for coupling with said threads of said coupling body and a substantially conically shaped bore extending longitudinally therethrough;
- a restriction ring disposed within said bore of said socket member and having a notch formed through a side thereof;
- a cover ring disposed adjacent said restriction ring and having a gasket disposed at a first end thereof, said first end being seated in said first bore and said cover ring having a stopper formed on an opposing second end thereof for contiguous contact with said restriction ring, wherein tightening of said socket member onto said coupling body clampingly engages said restriction ring to a pipe inserted into said first bore through said substantially conical bore of said socket member and respective openings in said restriction ring and said cover ring;
- a stopping ring mounted to said pair of stoppers of said inner pipe;
- an outer pipe having a threaded first end and a bore extending longitudinally therefrom, at least a portion of said inner pipe being sleeved in said outer pipe bore;
- a pressing device sleeved on said inner pipe and disposed adjacent said first end of said outer pipe;
- and,
- a locating cover threadedly engaged with said threads of said outer pipe and pressing said pressing device to provide sealing engagement with an inner surface of said outer pipe and an outer surface of said inner pipe, said inner pipe being slidable relative to said outer pipe.

- a valve member sleeved on said inner pipe and disposed in said outlet portion bore;
- and,
- a second socket member engaged with said fitting within said outlet portion bore to secure said valve member therein, said inner pipe being slidable and angularly displaceable relative to said outlet portion of said fitting .
