Flow regulating valve with variable section

Abstract

The invention relates to a flow regulating valve with a variable section, and belongs to the field of machines. The flow regulating valve with the variable section is characterized by comprising a valve shell (1), an elastic pipe (2) and a pressure controller (3). The external pressure applied on the elastic pipe (2) is adjusted through the pressure controller (3), so that the aim of changing a flow area of a medium flowing through the inner part of the elastic pipe is achieved, and flow regulation is realized.

Description

technical field [0001] The invention relates to a variable cross-section flow regulating valve, which belongs to the field of machinery. Background technique [0002] Flow regulating valve, also known as flow control valve and flow controller, is a commonly used component in the fluid field. The basic principle is to automatically control the opening of the valve according to the signal of the regulating part, so as to achieve the purpose of flow regulation. Most of the regulating valves used at present have direct contact between the control parts and the medium, and there is a great clothing risk. On the other hand, during the action of the control part, the cross-sectional shape of the flow channel of the medium is changed, the flow stroke is increased, the pipe resistance is increased, and energy is wasted. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a variable cross-section flow regulating valve, which...

Problems solved by technology

Most of the control valves currently used are in direct contact with the media, and there is a huge risk of clothing

On the other hand, during the action of the control part, the cross-sectional shape of the flow channel of the medium is changed, the flow stroke is increased, the pipe resistance is increased, and energy is wasted.
