Abstract
The utility model discloses a valve control device for agricultural irrigation, which comprises a butterfly valve (6), a transmission device, a motor (1) and a controller of the motor. A driving gear (2) connected with a direct current motor is meshed with a driven gear (3), the driven gear is connected with a speed changing device (5) through a screw rod arranged on a connecting arm (4), a rotating arm (8) and a switch that the rotating arm (8) can touch are arranged on the speed changing device (5), and the speed changing device is connected with the butterfly valve (6) through a connecting rod (7). By means of the butterfly valve, the valve control device for the agricultural irrigation can bear 10 atmospheric pressures, has a large pressure bearing range, and is wide in applicability. The valve is free of influence of water quality, tight in close, reliable in quality and substantially free of maintenance, thereby reducing maintenance cost. A control circuit and an interface circuit are simple and low in cost. The valve only consumes electricity during processes of opening and closing and is powered off at other time, thereby saving electricity.
Description
Technical field the utility model relates to a kind of valve control device, is a kind of agricultural irrigation valve electric control device specifically.
In the present agricultural irrigation of background technique, mainly be to control the water route by solenoid valve, the shortcoming of solenoid valve is that water pressure resistance is lower, the water sand content of stopping up water route, particularly agricultural irrigation easily is higher, and impurity is many, also stop up solenoid valve easily, bring bigger workload to maintenance.
The summary of the invention the purpose of this utility model is to provide a kind of agricultural irrigation valve control device, and the higher hydraulic pressure of its ability is not strict to water quality requirement, durable in use, reduces maintenance cost.
The technical solution of the utility model is as follows:
This device comprises butterfly valve, transmission device, motor and controller thereof; Driving gear that direct current generator connected and driven gear engagement, the leading screw of driven gear on link arm connects speed change gear, on this device cursor arranged, the switch that has cursor to touch on speed change gear; Speed change gear connects butterfly valve through connecting rod.
Above-mentioned controller is that two contact switchs insert motor, and the diode of power line one tunnel through oppositely connecting connects the contact switch of Open valve, and the diode that another road connects through forward connects the contact switch of throttle down, and another power line inserts motor.
Advantage of the present utility model is: 1, owing to use butterfly valve, withstand voltage about 10 barometric pressure, withstand voltage scope is big, uses wider.2, this valve is not subjected to the influence of water quality, closes tight.3, reliable in quality need not be safeguarded basically, reduces maintenance cost.4, control circuit, interface circuit are simple, and cost is low.5, power saving, valve are only being opened, are being closed power consumption in the closed procedure, and all the other times are in off-position.
Description of drawings Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model controller circuitry schematic diagram.
The utility model is described in further detail below in conjunction with accompanying drawing for embodiment.
By Fig. 1, can see that this device comprises butterfly valve 6, transmission device, motor 1 and controller thereof; Driving gear 2 that direct current generator connected and driven gear 3 engagements, the leading screw of driven gear on link arm 4 connects speed change gear 5, and cursor 8 is arranged on this device, the normally-closed contact switch that has cursor to touch on speed change gear; Speed change gear connects butterfly valve 6 through connecting rod 7;
Can see that by Fig. 2 the controller that motor M connected is two normally-closed contact K switch
