[0034] The working principle of a flow regulating valve based on the Venturi effect disclosed in the utility model is: when in use, the base 700 is first installed to the opening of a container (not shown in the figure) containing a second liquid to be mixed. When a mixed liquid is needed, the container containing the second liquid to be mixed is tilted so that the liquid outlet 500 is in a low position, and a low pressure is created at the outlet of the liquid outlet 500. The second liquid to be mixed passes through the third liquid circulation port 207 (at this time, the sealing ring 400 is pushed open by the water flow), the fourth liquid circulation port 602, the first liquid circulation port 102 and the gap between the connecting plate 105 and flows out from the outlet of the liquid outlet 500.

[0035] When the second liquid to be mixed flows through the area between the movable valve body 100 and the fixed valve body 200, due to the Venturi effect, the pressure inside the liquid storage bag 800 is greater than the pressure in the area between the movable valve body 100 and the fixed valve body 200. The first liquid to be mixed inside the liquid storage bag 800 pushes the umbrella-shaped plug 300 and flows out from the second liquid flow port 203, then flows into the top of the conical pressure cover 104 through the gap between the connecting plates 105, mixes with the second liquid to be mixed, and then flows out from the liquid outlet 500 together.

[0036] When it is necessary to adjust the proportion of the first liquid to be mixed in the mixed solution, it is only necessary to rotate the liquid outlet 500, and the liquid outlet 500 drives the movable valve body 100 to rotate at the same time. During the rotation of the movable valve body 100, under the action of the threaded groove 103 and the vertical plate 205, the movable valve body 100 slides inside the liquid outlet 500 at the same time, thereby adjusting the distance between the movable valve body 100 and the fixed valve body 200, thereby adjusting the proportion of the first liquid to be mixed in the mixed solution.
