Magnetorheological flow control valve

Abstract

The invention relates to a flow control valve, in particular to a magnetorheological flow control valve which realizes flow control through the opening degree of the control valve. The flow control valve comprises a jump ring, an upper end cover, an upper valve body, a lower valve body, a coil, a lower thrust spring, a valve core, a thrust shaft, an inner valve body, a working cavity, a magnetic isolation sleeve, a spring seat, an upper thrust spring, a seal bolt and a plurality of rubber seal rings; and according to the magnetorheological flow control valve, the shifting position of the valve core is controlled through a technical method in which the magnetic field intensity which acts on magnetorheological fluid in the working cavity formed between the magnetic isolation sleeve and the upper valve body is controlled, so that the magnetorheological fluid yield strength is affected and the action force of magnetorheological fluid to the thrust shaft is controlled, so that different circulation areas are obtained and the the control over the fluid flow is realized.

Description

technical field [0001] The invention relates to a flow control valve, in particular to a magneto-rheological flow control valve which realizes flow control by controlling the valve opening. Background technique [0002] Common flow control valves usually control the flow of fluid by controlling the flow area of ​​the channel. Traditional flow control valves design multiple different flow areas through mechanical design, and control different flows through switching. The disadvantages are: high machining accuracy requirements and poor product consistency; switching requires the design of auxiliary structures, resulting in complex structures ; Once the design is completed, the flow control cannot be changed, and it is difficult to achieve stepless control. With the development of technology, the flow control valve is required to develop in the direction of miniaturization, intelligence and economy. This requires the control structure of the flow control valve to the flow area...
