Title:
DIFFERENTIAL PRESSURE DYNAMIC STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/051415
Kind Code:
A1
Abstract:
A differential pressure dynamic structure, comprising a fluid pipeline (10) for flowing of a fluid and a differential pressure pipe, wherein the differential pressure pipe comprises a first main pipe (20) located in the fluid pipeline (10) and of which a direction of an opening of one end is opposite to a flow direction of the fluid, and a second main pipe (30) located in the fluid pipeline (10) and of which a direction of an opening of one end is the same as the flow direction of the fluid; axes of the first main pipe (20) and the second main pipe (30) and an axis of the fluid pipeline (10) are located on a same straight line; an opening of the other end of the first main pipe (20) is communicated with a first branch pipe (40) extending out of the fluid pipeline (10) and used for being connected to an external pipeline; and an opening of the other end of the second main pipe (30) is communicated with a second branch pipe (50) extending out of the fluid pipeline and used for being connected to the external pipeline. According to the differential pressure dynamic structure, the first main pipe (20) and the second main pipe (30) which are located in the fluid pipeline (10) are communicated by means of the first branch pipe (40) and the second branch pipe (50) to form a pipeline connected to the fluid pipeline (10) in parallel; the differential pressure dynamic structure can generate a relatively large differential pressure in a short distance, and is suitable for the fields such as chemical dosing, mixing of multiple components, cleaning of rubber balls.
