The required flow can be obtained by adjusting the oil quantity of the input hydraulic oil 5.
And (III) continuing to convey the hydraulic oil 5, and when the composite valve core 2 just generates enough deformation at the threaded joint installation plane to completely eliminate the flow area, the marine low-noise flexible composite throttling valve 14 is in an almost closed state. And the hydraulic oil 5 is continuously conveyed, the valve core is continuously deformed, and the marine low-noise flexible composite throttling valve 14 is in a completely closed state.
And (IV) when the cooling water flow of the thrust bearing 19 needs to be increased, the oil outlet control valve 15 is opened, the hydraulic oil 5 is sent back to the oil tank again by the pressure generated by the composite material valve core 2 when the initial state is recovered, the deformation of the composite material valve core 2 is reduced, the flow area is increased, and the cooling water amount is increased.
The heat exchanger 17 of the refrigerating unit and the low-noise flexible composite material throttle valve 14 corresponding to the cooling pipeline of the propulsion motor 18 are controlled according to the method, and then the required flow of each branch can be obtained.
