An electronic flow regulating valve

Abstract

The invention discloses an electronic flow regulating valve comprising a valve body, a valve needle, a push rod motor and a linear push rod. The valve body is provided with a first flow port, a second flow port and a valve port arranged between the first flow port and the second flow port; the valve needle is arranged inside the valve body, and the first end of the valve needle corresponds to the valve port; the push rod motor is provided with a motor casing, a rotor sleeve, a motor rotor and a motor stator; the linear push rod and the valve needle have a common axis, and the linear push rod is fixedly connected to the second end of the valve needle; and when the push rod motor works, the motor stator drives the motor rotor to rotate, the motor rotor further drives the linear push rod to move along the axis together with the valve needle, the opening degree of the valve port is adjusted, and the purpose of controlling the flow rate is achieved. The electronic flow regulating valve has the beneficial effects that flow regulation is implemented under control of electric signals, the flow rate is adjusted accurately, the response is fast, the motor rotates stably, the performance is reliable, and the service life is long.

Description

technical field [0001] The present invention relates to a flow regulating valve, in particular, an electronic flow regulating valve which is generally used for various fluids. Background technique [0002] At present, most flow control valves on the market are purely mechanical or single-purpose electronic flow control valves. The disadvantages are: 1. Manual adjustment is required; 2. The control accuracy is poor, and 3. The existing electronic flow control valves are single-purpose. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is the drawback brought by the pure mechanical type in the prior art, and a novel electronic flow regulating valve is provided. [0004] In order to achieve this purpose, the technical scheme of the present invention is as follows: an electronic flow regulating valve, comprising: [0005] a valve body, which has a first flow port, a second flow port, and a valve port disposed between the first flow ...
