Description
Technical field
The utility model is a kind of water injection rate control device of used for water injection wells in oil fields, is a kind of constant current amount injection well downhole flow regulator.
Background technology
The flow of used for water injection wells in oil fields gate valve control at present needs artificial changeover valve handwheel when regulating flow, flow-control is inaccurate, wastes time and energy; Efficient is low, and when line pressure fluctuateed, flow also can change; Need manual work to carry out controlled valve again and just can make flow reach the injection allocation requirement, because the pressure frequent fluctuation, the workman needs the frequent flow of regulating; Labor strength is big, can not guarantee work quality, can not satisfy the oil-field flooding requirement.
Summary of the invention
The purpose of the utility model is a kind of constant current amount injection well downhole flow regulator of design, makes it when pressure produces fluctuation, and flow does not change.
The purpose of the utility model is achieved in that and comprises throttling arrangement, water nozzle, single current valve seat, ball-and-seat, valve body, Flow-rate adjustment main body, flow assembly, Flow-rate adjustment screw, Flow-rate adjustment spring, Flow-rate adjustment piston, valve core spring, unlatching spool, unlatching valve seat that water inlet and delivery port are arranged on the valve body, at delivery port one end of valve body throttling arrangement is installed; Throttling arrangement is threaded with valve body, and the single current valve seat is installed on the throttling arrangement, and the single current valve seat is threaded with throttling arrangement; Water nozzle is installed in single current valve seat bottom; Ball-and-seat is installed in the single current valve seat, at water inlet one end of valve body the Flow-rate adjustment main body is installed, the Flow-rate adjustment main body is threaded with valve body; In the bottom of Flow-rate adjustment main body the unlatching valve seat is installed, opened spool; Open spool and supported by valve core spring, the Flow-rate adjustment piston is installed in the Flow-rate adjustment main body, the Flow-rate adjustment piston lower surface contacts with unlatching spool upper end; The Flow-rate adjustment spring is pressed on the Flow-rate adjustment piston; The Flow-rate adjustment screw is pushed down the Flow-rate adjustment spring, and the Flow-rate adjustment screw is threaded with the flow assembly, and the flow assembly is installed on the Flow-rate adjustment main body.
The beneficial effect of the utility model is: under differential pressure action, the distance of opening between spool and the unlatching valve seat also changes when pressure changes, and its opening degree of opening spool is changed; Thereby make the constant flow through the Flow-rate adjustment main body, therefore, the utility model can reach purpose of design; Do not need manual adjustment, labor strength is low, and work quality is high; Automaticity is high, has remarkable economic efficiency and social benefit.
Description of drawings
