Pump and valve integrated flow active control device and control method

Abstract

The invention provides a pump valve integrated flow active control device and control method. The control device comprises an excitation coil (1), a flow pass frame body (2), an opening and closing mechanism and a shaft body; the excitation coil (1) is arranged inside or outside the flow pass frame body (2); the shaft body is arranged inside the flow pass frame body (2); the opening and closing mechanism is mounted on the shaft body; the opening and closing mechanism can close the flow pass of the flow pass frame body (2) when unfolded and can open the flow pass frame body (2) when folded. According to an active opening and closing movement valve, active or self-adaptive opening and closing of the valve are realized through control, in the opening and closing control process of one or more valves, directional pumping pressure on the fluid passing through the valves can be realized by the coordination control of the opening and closing degrees and the opening and closing speeds of the valves in the opening and closing path, so that the fluid flow speed and the flow direction can be regulated and controlled, and the active pump functions are realized.

Description

technical field [0001] The invention relates to the field of pump and valve control, in particular to a pump and valve integrated flow active control device and control method. Background technique [0002] Traditional valves are only switching devices for on-off fluid, and cannot be used to adjust fluid flow rate, flow direction or pressure of fluid flow. Moreover, the pump system and the valve system are separate components, so that the flow control device formed as a whole has many components, large volume, and many control links with poor reliability. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide an active control device and control method for integrated pump and valve flow. [0004] According to the present invention, a pump and valve integral flow active control device includes an excitation coil, a flow channel frame body, an opening and closing mechanism, and a shaft body; [0005] The...
