Abstract

The invention provides a rotary multi-level flux regulating valve. A shell of the valve is provided with a cylindrical or spherical cavity; the shell of the valve is provided with two passages that can lead the cavity to be communicated with the outside nonlinearly; and the two passages are respectively called an inflow cavity and an outflow cavity of the shell of the valve. The rotary valve body of the valve is a shell with the cylindrical or spherical cavity and is provided with a plurality of throttling holes; the rotary valve body is provided with a cylindrical connecting handle so as to be further connected with a stepping device; a close cover of the shell of the valve is a plate body with a hole or a spherical concave surface; and the connecting handle used for connecting the rotary valve with the stepping power device can pass through the hole. In the invention, the change of the flux of the fluid can be accurately controlled on multi-level, the structure is simple and the cost is low.

Description

technical field [0001] The present invention relates to a fluid flow regulating device in life or industrial and agricultural processes, in particular to multi-position precise control of liquid or gas (collectively referred to as fluid) logistics in life or industrial production, the most obvious is to make the fluid in the hydraulic control system Flow rate is a precise controller (device) for fluid flow in multiple levels. Background technique [0002] Whether in life or in industrial and agricultural production, the control of fluid flow is a common and important task. Especially when multiple levels of precise control of flow are required, this often becomes a cumbersome task. [0003] Traditionally, this work has been regulated by valves placed in pipelines that continuously change the fluid flow area. However, if the precise adjustment is frequently alternated between several levels, this kind of work becomes an operation that bothers the adjustment result and easil...
