The utility model discloses a valve control device includes drive shaft 1, a plurality of drive gear 2 and a plurality of driven gear, wherein: the drive shaft 1 can rotate around its own axis; a plurality of driving gears 2 are installed on the driving shaft 1 at intervals along the length direction of the driving shaft 1; each driven gear is coaxially and fixedly arranged on the corresponding hand wheel, and the plurality of driven gears are in one-to-one corresponding transmission connection with the plurality of driving gears 2.
When the drive shaft 1 rotates around the axis of the drive shaft 1, the drive shaft 1 can drive the plurality of drive gears 2 installed thereon to rotate together, the plurality of drive gears 2 can drive the plurality of driven gears in transmission connection with the plurality of drive gears one to one, and because each driven gear is coaxially and fixedly installed on the hand wheel of the corresponding valve, the rotation of the driven gear drives the hand wheel to rotate, so that the operation of controlling the valve is realized. The utility model discloses only can realize the purpose of opening and close of a plurality of valves of simultaneous drive through a drive shaft 1, promptly, carry out centralized control to the switch of a plurality of valves to reduce the quantity, the reduce cost of electric head, and reduce workman work load.
It should be understood that the plurality of driven gears and the plurality of driving gears 2 may be in one-to-one transmission connection in various ways. For example, most directly, a plurality of driven gears and a plurality of driving gears 2 may be in meshing connection in one-to-one correspondence. In some embodiments of the present invention, since there is a certain distance between the driving shaft 1 and the driving gear 2 and the hand wheel of the valve, this allows a certain distance between the driven gear coaxial with the hand wheel and the driving gear 2, and therefore, optionally, the valve control device includes a plurality of chains, and each driven gear is connected with its corresponding driving gear 2 through a corresponding chain transmission.

Through the technical scheme, under different conditions, operators can select which valves need to be uniformly controlled and which valves do not need, and the flexibility of valve integrated control is greatly improved.
In order to achieve the above technical solution, optionally, the at least one driving gear 2 is switched between the first state and the second state by a synchronization mechanism, the driving shaft 1 is provided with first key slots at intervals along the length direction, the at least one driving gear 2 is provided with second key slots, and the synchronization mechanism includes a connection key 3 capable of providing connection between the first key slots and the second key slots. That is, when a portion of the connecting key 3 is located in the first key groove, the rotation of the driving shaft 1 also moves the connecting key 3, and at this time, if another portion of the connecting key 3 is also located in the second key groove, the movement of the connecting key 3 rotates the driving gear 2. When the driving gear 2 is not required to rotate, the connecting key 3 can not extend into the first key groove and the second key groove simultaneously. It should be understood that the driving gear 2 may be switched between the first state and the second state by other means, which is not limited by the present invention.
To facilitate handling of the connection key 3, it is optional that the connection key 3 is at least partly located in the first keyway, and that the connection key 3 is movable in the radial direction of the drive shaft 1 to be located either fully in the first keyway or partly in the second keyway. In other words, when it is desired to bring the drive gear 2 into the first state, the connecting key 3 is moved towards the second keyway so that a portion of the connecting key 3 remains in the first keyway and another portion protrudes into the second keyway. When it is desired to drive the gear 2 into the second state, the connecting key 3 is moved towards the first keyway so that it is fully located in the first keyway, thereby not providing a connection between the first keyway and the second keyway.
Of course, the radial movement of the connecting key 3 can be driven in various ways, in some embodiments of the present invention, optionally, the synchronizing mechanism comprises a switching handle 4 mounted on the drive shaft 1, the switching handle 4 being capable of pressing the connecting key 3 completely into the first keyway.
After the switching handle 4 presses the connecting key 3 completely into the first key groove, it is necessary to keep the connecting key 3 in a state of completely entering the first key groove, and therefore, alternatively, the synchronizing mechanism includes a stopper 5 fixedly provided to the drive shaft 1, and the stopper 5 can restrict the switching handle 4 in a state of keeping the connecting key 3 pressed.
