Abstract

The invention relates to an adjusting valve system having an energy regeneration effect. The system comprises the adjusting valve, an energy regeneration mechanism, and an execution mechanism, whereinthe adjusting valve comprises a valve shell, wherein a flow channel is arranged in the valve shell, and a movable valve core is arranged in the flow channel; the energy regeneration mechanism comprises an energy regeneration cavity body structure connected with the valve shell; the energy regeneration cavity body structure comprises a first cavity body structure and a second cavity body structure; an internal space of the first cavity body structure communicates with the flow channel; a first piston is arranged and is elastically connected with a cavity body wall of the first cavity body structure; a second piston which can do synchronous motion together with the first piston is arranged in the second cavity body structure; two cavity bodies which are divided by the second cavity body structure are connected with an energy storage mechanism and an oil tank through the second piston; the execution mechanism comprises a hydraulic cylinder; and the hydraulic cylinder is connected with avalve core and is also connected with the energy storage mechanism. The adjusting valve system disclosed by the invention has the advantages that energy produced by fluid oscillation can be effectively absorbed and utilized, so that the operation stability of the adjusting valve is improved.

Description

technical field [0001] The invention relates to the technical field of regulating valves, in particular to a regulating valve system and method with capacity regeneration function. Background technique [0002] Control valves are widely used in various fluid control occasions. The inventors have found that under extreme working conditions, when the fluid controlled by the regulating valve oscillates violently, the spool of the regulating valve is likely to bear sudden additional loads. The fluid control on the ship is also inseparable from the regulating valve. Ship control valves play a key role in ensuring the normal fluid delivery of ship power systems. Practice has proved that the environment of the ship is complex and changeable. With the change of various working conditions, the sudden additional load borne by the control valve may greatly exceed the rated load, resulting in the failure of the actuator of the valve, reducing the control accuracy and endangering the s...
