Abstract

The invention provides a proportional valve. The proportional valve comprises a first half valve body (1) and a second valve body (2) fixedly connected with the first half valve body (1), wherein a cavity is formed between the first half valve body (1) and the second half valve body (2), and the cavity is communicated with an air inlet (11) and an air outlet (4) of the proportional valve, the proportional valve also comprises: a pivot angle control assembly (3) arranged in the cavity, and the openness of the air inlet (11) is controlled by rotating the pivot angle control assembly (3). The proportional valve provided by the invention has the properties of flexible mechanism, stable precision, high controllability and the like.

Description

technical field [0001] The invention relates to the field of flow control, in particular to a proportional valve. Background technique [0002] In current engineering practice, the mainstream flow proportional control valve is displacement proportional control valve. Most of these proportional valves use the core parts to control the flow through the linear displacement of the parts under the action of electromagnetic field and mechanical force. The flow control is carried out by the linear displacement of the parts, which not only brings about the airtightness of the structure, but also causes wear of the parts and reduces the service life of the proportional control valve. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned defects existing in the existing proportional valve, and provide a proportional valve with flexible mechanism, stable precision and high controllability. [0004] In order to achieve the above obje...
