Abstract
A riser manifold assembly includes a control valve, a first spool pipe, a flow control switch, a check valve, a second spool pipe, and a test and drain valve. An inlet of the first spool pipe being mechanically coupled and fluidly sealed with an outlet of the control valve. The flow control switch being mechanically mounted to the first spool pipe. An inlet of the check valve being mechanically coupled and fluidly sealed with an outlet of the first spool pipe. An inlet of the second spool pipe being mechanically coupled and fluidly sealed with an outlet of the check valve. The test and drain valve being mechanically coupled and fluidly sealed with an auxiliary port of the second spool pipe.
Claims10
A riser manifold assembly comprising:
- a control valve defined by an inlet and an outlet, being operable between an open position, permitting fluid flow between the inlet and the outlet, and a closed position, inhibiting fluid flow between the inlet and the outlet;
- a first spool pipe defined by an inlet and an outlet, the inlet of the first spool pipe being mechanically coupled and fluidly sealed with the outlet of the control valve, the first spool pipe having a flow port between the inlet and the outlet of the first spool pipe;
- a flow control switch having a vane inserted in the flow port of the first spool pipe and the flow control switch mechanically mounted to the first spool pipe creating a fluid seal between the flow control switch and the flow port;
- a check valve defined by an inlet and an outlet, the inlet of the check valve mechanically coupled and fluidly sealed with the outlet of the first spool pipe, the check valve having a valve seat and a clapper, the clapper being movable between an open position, allowing fluid flow from the inlet to the outlet, and a closed position, inhibiting fluid flow from the outlet to the inlet, according to a pressure differential between the inlet and the outlet, the check valve including:
- a first pressure port located between the valve seat and the outlet of the check valve;
- and
- a first auxiliary port located between the valve seat and the outlet of the check valve;
- a second spool pipe having an inlet and an outlet, the inlet of the second spool pipe being mechanically coupled and fluidly sealed with the outlet of the check valve, the second spool pipe having a second auxiliary port located between the inlet and the outlet of the second spool pipe;
- a first pipe coupling that couples the check valve with the first spool pipe and a second pipe coupling that couples the second spool pipe with the check valve such that the control valve, the first spool pipe, the check valve, and the second spool pipe are rotatably adjustable about a longitudinal axis through the first spool pipe, the first pipe coupling, the check valve, the second pipe coupling, and the second spool pipe;
- and
- a test and drain valve mechanically coupled and fluidly sealed with the second auxiliary port of the second spool pipe.
