Abstract

The invention discloses a rotary valve. A base comprises a baseplate horizontally arranged, and side plates oppositely arranged on two sides of the baseplate; fixed shafts are symmetrically arranged on two inner sides of a door frame; the fixed shafts both extend to the side plates and penetrate through the side plates; a valve element comprises two valve gears vertically and oppositely arranged; the two valve gears are connected through a valve plate; two sides of the valve plate are fixedly clamped in radial grooves; the valve gears are adapted to the side plates; rotating holes matched with the fixed shafts are formed in the circle centers of the valve gears; the valve gears are rotationally bonded on the side plates through matching between the rotating holes and the fixed shafts; a transmission device is positioned above the valve element, and comprises driving gears respectively arranged above the valve gears; the driving gears are both rotationally arranged on a rotating shaft in the door frame; the driving gears are engaged with the valve gears; and one end of the rotating shaft is connected with a driving source. The distances from center shafts of the fixed shafts to the baseplate are equal to the radiuses of gear top circles of the valve gears; and the connecting edges of the valve plate and the valve gears are equal to the diameters of the gear top circles of the valve gears.

Description

technical field [0001] The invention relates to a rotary gate. Background technique [0002] Channel gates are widely used in the agricultural field of our country. It is a farmland water-saving irrigation control device developed for the end-level canal system irrigation and drainage of farmland and dryland water-saving control irrigation technology. Traditional canal gates mainly focus on the opening and closing functions of the water gates, such as the widely used hemispherical water control gates, plane cast iron sliding gates and one-way gates, all of which control the irrigation of the canal by manually or electrically controlling the opening and closing of the gates . However, the opening and closing of these channel gates consumes a lot of power, and the accuracy of water control is low, so it is difficult to be applied in the development of modern precision agriculture. Therefore, designing a channel gate with high reliability and low power consumption for openin...
