The pressure supply is different and has different effects. For example, the same venturi tube is installed in a place with a large water pressure and a place with a small water pressure, and the effect is different, so the fixed venturi structure does not match. Ideal for a wide range of applications. Therefore, how to design a venturi that can be used according to different kinds of objects and can adjust the pressure difference is the target. [New content] [0004] In view of the problems of the prior art, the main purpose of the present invention is to provide a venturi tube with a adjusted diameter structure, which is provided with a valve member at the near exit end of the venturi to adjust the outlet. The degree of opening, in turn, adjusts the pressure difference within the venturi.
