[0029] Preferably, the adjusting nut is a T-shaped adjusting nut.
[0030] Preferably, the flow channel 13 is a gradually converging / diverging flow channel.
[0031] Working principle: A controllable liquid flow regulating device. Initially, each regulating valve core 320 is in a closed state, that is, the regulating hole 311 is not connected to the flow pipe body 1; the regulating cone 24 is in the initial position, that is, the minimum flow cross-sectional area is formed between the regulating cone 24 and the contracted inner wall surface of the flow pipe body 1, and the flow rate passing through is the smallest at this time. After the liquid enters the flow pipe body at a certain pressure, the flow cross-sectional area formed between the regulating cone 24 and the contracted inner surface of the flow pipe body 1 can be changed to achieve flow regulation; if the flow rate is to be increased, different regulating valve assemblies 32 can be selected according to the flow requirements and the regulating valve core 320 can be rotated 90° clockwise, so that only the regulating valve core 320 is connected to the regulating hole 311, and the liquid flows into the regulating hole 311 and acts on the regulating disc 33. The regulating disc 33 is moved by the pressure and then contacts the moving rod 25, pushing the moving rod 25 and the moving disc 22, so that the moving disc 22 compresses the adjusting spring 23, and then the moving disc 22 drives the adjusting cone 24 to move backward to a certain position, thereby increasing the flow rate. The flow cross-sectional area between the regulating cone 24 and the contracted inner surface of the flow pipe body 1 ultimately achieves the purpose of increasing the flow rate; if the flow rate needs to be reduced, the opened regulating valve core 320 can be rotated counterclockwise by 90° according to the flow rate requirement, so that the regulating hole 311 is connected with the leakage hole 312 and the leakage channel 14, and the liquid flow acting on the regulating disc 33 in the regulating hole 311 flows to the downstream of the flow pipe body 1 under the action of the pressure difference. Since the liquid flow pressure acting on the regulating disc 33 disappears, the moving disc 22 drives the regulating cone 24 to move forward to a certain position under the action of the regulating spring 23, thereby reducing the flow cross-sectional area between the regulating cone 24 and the contracted inner surface of the flow pipe body 1, and ultimately achieving the purpose of reducing the flow rate.
