Self-adaptive turbo-flow nozzle

Abstract

The invention provides a self-adaptive turbo-flow nozzle, which comprises a nozzle body, a turbulent flow piece and multiple elastic units. The nozzle body is provided with an air inlet end part and an air outlet end part, and is sequentially provided with a laminar flow cavity and a turbulent flow cavity along a direction from the air inlet end part to the air outlet end part; a cross section area of the turbulent flow cavity is gradually reduced along the direction from the air inlet end part to the air outlet end part; and the turbulent flow piece can be movably arranged in the turbulent flow cavity along a direction parallel to a central axis of the nozzle, and is connected with an inner wall of the nozzle body through the elastic units. By adopting the self-adaptive turbo-flow nozzleprovided by the technical scheme of the invention, the nozzle can meet the demand on high-accurate adjustment, can be used for automatically adjusting the fluid velocity and automatically adapting toturbulent effects produced by the nozzle under different velocities, can be beneficial to automatically improving the output airflow velocity maximally, and is low in cost and more stable and convenient to adjust a fluid.

Description

technical field [0001] The invention relates to the technical field of fluid nozzles, in particular to an adaptive turbulent flow nozzle. Background technique [0002] At present, there are two kinds of fluid nozzles that are relatively common. One is a structure with variable cross-section. Specifically, the fluid input end has a wider cross-section, and the fluid flows out from a narrower cross-section to achieve fluid acceleration. The style structure is simple and the market share is high. However, when faced with high-end requirements, such as typical turbulent flow rate control, this simple variable-section nozzle style cannot meet this high-level requirement. The other is to manually adjust the opening valve of the nozzle of the nozzle. When the turbulent flow needs to be sprayed at a higher flow rate, it is only necessary to adjust the opening of the valve to make the fluid flow through a smaller channel to obtain a high flow rate; otherwise, When a relatively loos...

Problems solved by technology

Obviously, the use of the latter nozzle inevitably requires manual participation. However, in reality, the application of this nozzle is greatly restricted due to the adverse effects of most on-site environments on humans.

[0003] To sum up, the adjustment accuracy of fluid nozzles in the prior art is not high enough to meet high-level adjustment requirements. In addition, there are also nozzles that are adjusted through valves, but the adjustment requires manual participation, which is inconvenient to adjust and control, and improves the production of nozzles. cost
