摘要: In a choke valve having a cage with external sleeve flow trim, the large ports of the cage are aligned with the axis of the inlet bore and a deflection bar is positioned at the top end of the main bore, opposite to the inlet bore. The flow patterns within the choke are consequently altered with significant reduction of localized erosional wear areas.

摘要: In a sub-sea wellhead insert-type choke valve having a bonnet, a pair of pressure transmitters are mounted in the bonnet. One transmitter is connected by a passageway with the annular clearance between the cartridge of the insert assembly and the valve body. This transmitter measures the pressure of the fluid in the clearance and transmits signals indicative thereof to a receiver at surface. The other transmitter is connected by a passageway with the fluid in the valve outlet, measures the pressure of this fluid and transmits signals indicative thereof to the receiver. In this way the high and low pressures upstream and downstream of the choke valve flow trim are monitored by transmitters, which can be serviced by bringing the insert assembly to surface.

摘要: The invention provides a choke system with hydraulic circuits which provide choke valve positioning that can be varied by the use of incremental steps. The incremental movement action in either the opening or closing direction is accomplished through the use of one of the two hydraulic slave cylinders which can either add or subtract a fixed volume of hydraulic fluid from the choke actuator. A series of check valves provides direction for flow in the hydraulic lines, locking of the choke actuator, and re-filling of the slave cylinders during operation. The system eliminates excessive lines or solenoid valves and avoids the need for mechanical locking mechanisms. Preferred embodiments include a “fast close” system which, instead of running through a series of steps to close the valve, provides valve control in a fast close line to move the choke actuator to the full closed position from anywhere in the travel over a shorter period of time than through normal stepping operation.

摘要: A reverse flow insert assembly is provided wherein the flow trim of the choke valve is positioned horizontally within the tubular cartridge, so that the cage bore outlet is aligned with the valve body side opening. A collar is provided to throttle the flow ports of the cage. The valve stem assembly is adapted to bias the collar along the horizontal side wall of the cage. The resulting insert assembly can be positioned in the valve body to modify the valve for fluid injection service on a sub-sea wellhead.
