AI Technical Summary
Existing fixed and moving valve plate designs cannot simultaneously control the opening and closing of multiple water conveyance passages and the conveying flow rate within the valve, thus limiting their application in agricultural irrigation.
A fluid control valve is designed by setting a spacer strip on a fixed valve plate to separate through holes, and setting a through hole on a moving valve plate with an area larger than the spacer strip but smaller than the sum of the areas of adjacent through holes. When the moving valve plate rotates, it can simultaneously connect or disconnect with adjacent through holes, thereby achieving simultaneous control of multiple passages.
It enables simultaneous control of the opening and closing of multiple water transmission channels and the transmission flow rate, avoiding blockage by impurities inside the valve body and improving the versatility and sealing performance of the valve body.
