Title:
AXIAL-FLOW TYPE FLOW CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2022/218166
Kind Code:
A1
Abstract:
An axial-flow type flow control valve, comprising: a valve body (1), a valve core (2), a valve seat (4), and a driving apparatus. The valve core (2) is fixedly provided inside the valve body (1), and an annular fluid channel is formed between the valve core (2) and the valve body (1); the valve seat (4) is tubular and sealingly connected to the inner wall of the valve body (1); the valve body (1), the valve core (2), and the valve seat (4) are coaxially arranged; the driving apparatus is used for driving the valve seat (4) to move in the axial direction of the valve body (1) so as to be connected to or separated from the valve core (2), so as to close or open the flow control valve. By means of the flow control valve, the problems of the instability of the overall contour of a throttling member, flow separation, and increased flow resistance and the like caused by the driving apparatus driving the valve core to move are solved.
