[0025] The detailed description and technical content of the present invention are described as follows with the accompanying drawings. However, the accompanying drawings are only for reference and description, and are not used to limit the present invention.
[0026] As attached Figure 1-3 As shown, a rotary valve-type pressure pulse generator includes a cylinder structure formed by connecting an upper joint 1, an outer cylinder 6, and a lower joint 7 in sequence. An overflow channel is formed inside the cylinder structure, and the rotary valve 2 is further included. The rotary valve is installed inside the cylindrical structure. The rotary valve includes a stator 21, a rotor 22, and a main shaft 23. The stator is provided with a flow hole, the rotor is fixed on the main shaft, and the rotor rotates around the main shaft to affect the flow on the stator. The hole changes the flow area.
[0027] A drive mechanism is also arranged inside the cylinder structure, and the power outpu...
