Abstract
A pressurized fluid is "let-down" to atmospheric pressure as it passes through a choke assembly having two pressure orifices (choke flow beans) which are in-line and directly opposite and which are designed to deliver jet streams of generally equal force to a common in-line focal point. The choke assembly is a fixed-rate system where the volume throughput is regulated primarily by the pressure on the fluid.
Claims7
A choke assembly for reducing the pressure of high pressure fluids to essentially atmospheric pressure consisting essentially of:
- (a) a source of high pressure fluid which is in fluid communication with
- (b) a conduit containing a remotely controlled hydraulically actuated valve which regulates the flow of fluids through said conduit and which discharges into
- (c) a means for dividing the high pressure fluid into two generally equal streams which flow into
- (d) separate conduits directing each of said equal streams to
- (e) one of two choke flow beans which are positioned in-line and directly opposite each other and which are designed to deliver jet streams of fluid of generally equal force to a common in-line focal point which is
- (f) enclosed in a container from which the fluid is collected and withdrawn at generally atmospheric pressure.
