Abstract
A blocker apparatus (20) for blocking a stream (22) of high-pressure fluid includes a blocking member in the form of a sphere or ball (30), or a rod (160) receivable within a partially surrounding seat (34/162) at the forward end of a seat carrier (40) to rotate in the seat. The seat carrier (40) is extended and retracted by an actuator (32) to place the blocking member within the path of the stream (22) and/or remove the blocking member from the path of the high-pressure stream. The blocking member is replaced by simply lifting the blocking member (30/160) off of the seat (34/162) and lowering a new blocking member into the seat.
Claims17
An apparatus for deflecting the flow of a high-pressure stream of fluid, comprising:
- a spherically shaped blocking member;
- a seat that is at least partially circular in shape for receiving and supporting the spherical blocking member, the seat configured to enable the blocking member to change position within the seat during operation of the apparatus;
- an actuator system connected to the seat for advancing the blocking member into the high-pressure fluid stream to disrupt and deflect the flow of the high-pressure fluid stream and/or for retracting the blocking member out of the high-pressure fluid stream to end the disruption and deflection of the flow of the high-pressure fluid stream;
- and
- wherein the blocking member is movable relative to the seat when struck by the high-pressure fluid stream to present a different portion of the blocking member to the high-pressure fluid stream
- wherein the seat at least partially surrounds and supports the underside of the spherically-shaped blocking member, whereby the spherically-shaped blocking member may be positioned on the seat by setting the spherically-shaped blocking member downwardly onto the seat
- wherein the seat is in the shape of a partial sphere.
An apparatus for deflecting the flow of a stream of high-pressure fluid used for cutting, the apparatus comprising:
- a spherically shaped blocking member;
- a seat that is at least partially circular in shape to correspond to the shape of the spherically shaped blocking member and to receive and support the blocking member and permit the blocking member to shift relative to the seat under the influence of flow of the stream of high-pressure fluid;
- an actuator system connected to the seat for moving the blocking member into the stream of high-pressure fluid to disrupt and deflect the flow of the high-pressure fluid stream and for moving the blocking member out of the stream of high-pressure fluid to not disrupt and deflect the flow of the high-pressure fluid stream;
- and
- a retainer for preventing the blocking member from becoming removed from the seat while the high-pressure fluid is being disrupted and deflected by the blocking member
- wherein the seat at least partially surrounds and supports the underside of the spherically-shaped blocking member, whereby the spherically-shaped blocking member may be positioned on the seat by setting the spherically-shaped blocking member downwardly onto the seat
- wherein the seat is in the shape of a partial sphere.
