Abstract

The invention discloses an electric servo valve. The electric servo valve comprises a servo motor, a valve body and a valve element; an output shaft of the servo motor is fixedly connected with one end of the valve element; the valve element is positioned in the valve body; a first ventilation groove is formed in the peripheral direction of the valve element; the valve body is provided with a first intake port and a first exhaust port in the positions passing through the cross section of the first ventilation groove; and when the valve element rotates to a certain angle, the first intake port,the first ventilation groove and the first exhaust port communicate with each other. The electric servo valve realizes the flow and air circuit control through driving by the servo motor, the valve body and the valve element, and integrates such performances as high action sensitivity, excellent flow adjustment dynamic performance and integration of air pressure adjustment and air circuit change.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an electric servo valve. Background technique [0002] In existing industrial production, it is often necessary to use pneumatic valves or pneumatic valves to realize air flow control, such as two-position three-way valves, which are widely used. However, most existing pneumatic valves or pneumatic valves such as two-position three-way valves have disadvantages such as low action sensitivity, poor dynamic performance of flow regulation, and difficulty in integrating or integrating air pressure regulation and gas circuit switching, which greatly limits its use. Contents of the invention [0003] In view of the above deficiencies, the present invention provides an electric servo valve, which can realize high action sensitivity, excellent dynamic performance of flow regulation, air pressure regulation and integration of air circuit switching and other performances. [0004] To ac...
