The invention belongs to the technical field of valves, and particularly relates to a sector type valve plate type flow control valve. The flow control valve comprises a valve body, a first sector type valve plate, a second sector type valve plate, a worm, a servo motor, a first sealing ring and a second sealing ring. According to the flow control valve, the servo motor is started to drive the worm to rotate, the worm rotates to drive the second sector type valve plate to rotate, and the first sector type valve plate is fixedly connected with the valve body, so that the second sector type valve plate rotates to enable the first sector type valve plate and the second sector type valve plate to move relatively, and then opening and closing of the flow control valve can be controlled; an electric signal is transmitted to the servo motor through a controller, and the rotating angle of the second sector type valve plate can be controlled, so that the area of an opening between the first sector type valve plate and the second sector type valve plate is controlled, and then the flow control valve can control the flow passing through the valve body; and when the second sector type valve plate rotates by a certain angle, the second sector type valve plate is uniformly stressed, so that the situation that the second sector type valve plate is deformed and damaged when the pressure is too high is avoided.
Description
technical field [0001] The invention belongs to the technical field of valves, in particular to a fan-shaped valve plate flow control valve. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. The flow control valve is a valve that controls the flow of the orifice by changing the fluid resistance of the orifice under a certain pressure difference, thereby adjusting the movement speed of the actuator (hydraulic cylinder or hydraulic motor). It mainly includes throttle valve, speed control valve, overflow throttle valve and diversion and flow valve. The installation form is horizontal installation. The connection method is divided into flange type and thread type; welding type. The control and adjustment methods are divided into automatic and manual. [0003] Most of the existing flow control valves control the flow...
