Catcher wheel, axle top are provided with the positioning ring groove for coordinating positioning bead and spring in through hole, and axle bottom is fixedly connected and canine tooth
The little gear of engagement is taken turns, the through hole on the axle bottom insertion cap provided with axial rectangular cavity；Bottom goes out provided with parallel in valve body
Liquid mouth and inlet, valve internal upper part are provided with the longitudinal threaded bore of with liquid inlet and outlet connection and corresponding cap through hole, screwed hole
The interior valve element for being provided with sealing ring and being connected through a screw thread, the rectangular cavity of the square pole insertion gear shaft on valve element top.
In automatically controlled state, motor driven decelerator, output shaft, cam, gear train and gear shaft rotate this double-control valve,
One side cam rotation touches travel switch afterwards in place makes motor braking, and another aspect gear set drive gear shaft rotates and makes valve
Core moves up and down, so as to complete the keying of valve.In the automatically controlled failure of valve, handle wheel can be gone up, repositions gear
Axle, depart from two gears.Then, then by forward and reverse rotation hand wheel, gear shaft move up and down, realize the manual of valve
Open and close.
This double-control valve design science, it is practical, it is simple in construction, it is easy to use, any more shower nozzles can be fitted in and planted
Protect mechanically, the equipment part of excellent performance.When disaster breaks out, this double-control valve can fully ensure that plant protection equipment safety,
It is safe and efficiently work, protect crops from heavy losses.
