Abstract

The invention discloses a flow regulating valve with a stroke amplifying mechanism. The flow regulating valve comprises a base, wherein an outer shell is installed on the base; one end of the outer shell is connected with a movable rotating shaft; the other end of the movable rotating shaft is fixedly connected with a vertical plate; the side, away from the movable rotating shaft, of the bottom end of the vertical plate is connected with a buoy through a fixing rod; a cavity is formed in the outer shell; a floating lifting adjusting device is installed in the cavity; a water outlet is formed in the base; strip-shaped grooves matched with a valve plate are formed in the positions, located on the two side walls of the water outlet, of the base; and a trigger alarm device extending into the cavity is arranged at the top of the outer shell. The flow regulating valve has the beneficial effects that the flow regulating valve is simple to operate and convenient to install and fix, the opening and closing degree of the valve plate can be determined according to the height of the water level, so that the flow can be adjusted, the whole device is more sensitive and reliable under the overall friction coefficient, and the flow regulating valve has the functions of water level detection and automatic alarm.

Description

technical field [0001] The invention relates to the technical field of float control flow regulating valves, in particular to a flow regulating valve with a stroke amplification mechanism. Background technique [0002] Due to its high adjustment accuracy, low cavitation, noise and vibration, good energy dissipation effect, and ideal flow-opening curve, it is easy to realize automatic control. It has been widely used in many large-scale water transmission projects. According to dispatching needs , adjust the opening of each flow regulating valve, so that the flow through the valve matches the water flow of the pumping station, so that the whole system is maintained in a stable state, and the flow state of the water body in the pipeline is stable. Set the control water level amplitude range of each regulating tank, and maintain the water level within the range by controlling the flow of the flow regulating valve. The control water level setting should fully consider the impact...
