Abstract
Embodiments of the invention provide a high integrity pressure protection system (HIPPS) manifold including a housing providing a flow path between a process fluid line and a sensor, a first ball valve positioned within the housing and selectively allowing and inhibiting flow through the flow path, and a second ball valve positioned within the housing and selectively allowing and inhibiting flow through the flow path.
Claims20
A high integrity pressure protection system (HIPPS) manifold comprising:
- a housing providing a sensor flow path between a process fluid line and a sensor, and a vent flow path;
- a first valve positioned within the housing and selectively allowing and inhibiting flow through the sensor flow path, the first valve including a first cam;
- a second valve positioned within the housing, providing flow along the sensor flow path, and selectively allowing and inhibiting flow to the vent flow path, the second valve including a second cam;
- and
- a third valve positioned within the housing and selectively allowing and inhibiting flow through the sensor flow path, the third valve including a third cam, the first cam interacting with the second cam to inhibit movement of the second valve, and the second cam interacting with the third cam to inhibit movement of the third valve.

A high integrity pressure protection system (HIPPS) installation comprising:
- three HIPPS manifolds, each including
- a housing providing a flow path between a process fluid line, a vent, and a sensor,
- a first valve positioned within the housing and selectively allowing and inhibiting flow through the flow path,
- a second valve positioned within the housing and selectively allowing and inhibiting flow through the flow path,
- a third valve positioned within the housing and selectively allowing and inhibiting flow through the flow path, and
- a locking mechanism that includes a keyhole actuatable between a locked position and an unlocked position, a locking member movable in response to the keyhole between a locked position and an unlocked position, the locking member allowing actuation of the first valve when in the open position and inhibiting actuation of the first valve when in the locked position;
- and
- three individual keys, each one of the three individual keys corresponding to one of the three keyholes and configured to actuate the associated locking mechanism.
