The control device mainly comprises a valve electric actuator, a main valve coupling sleeve, a first crank, a first radial bearing, a connecting rod, a second radial bearing, a second crank and an auxiliary valve coupling sleeve, wherein the valve electric actuator is connected to the rotating shaft of the main valve through the main valve coupling sleeve and fixed by keys for controlling the on and off of the main valve; the first crank is installed on the main valve coupling sleeve and connected to the connecting rod through the first radial bearing for sending the output driving of the valve electric actuator to the connecting rod; the other end of the connecting rod is connected with the second crank through the second radial bearing; the second crank is connected with the rotating shaft of the auxiliary valve through the auxiliary valve coupling sleeve; and the output driving of the valve electric actuator controls the on and off of the auxiliary valve through the second crank.
Description
Technical field
The utility model relates to the control gear of a kind of valve control device, particularly a kind of dual-valve linkage, can form control to two valves simultaneously.
Background technique
Valve is to be applied to the usual means of fluid circuit with the characteristics such as flow, direction of control fluid.Particularly in modern industry, obviously be unpractical to the control of valve for manual fully realization.So Electric actuator is realized the control of valve by applying in the reality more and more widely.For some special field, then the control to valve has some special demands.For example,, often need especially to control different medium, use, make more to correspond to actual needs such as the switching of water and foam by two medium pipeline valves of a device control as the corollary equipment of fire-fighting monitor in the fire-protection equipment field.But can not control in the prior art, the device of two valves as mentioned above simultaneously.
The model utility content
The purpose of this utility model provides a kind of device that can form control simultaneously to two valves.This device also can be controlled another valve in by valve of electric device for valve control, another is in the state of pass when making these two valves open and close or make these on two valves to be in out simultaneously.
The scheme of the utility model technical solution problem is: electric device for valve (1), main valve joint sleeve (2), first crank (3), first plain radial bearing (4), connecting rod (5), second plain radial bearing (6), second crank (7), secondary valves connecting sleeve (8), described electric device for valve (1) is connected on the rotatingshaft of main valve by main valve connecting sleeve (2), and fix with key, control the keying of this main valve; Described first crank (3) is installed on the main valve connecting sleeve (2), and is connected to connecting rod (5) by first plain radial bearing (4), the output of electric device for valve (1) is driven be sent to connecting rod (5); Described connecting rod (5) the other end connects second crank (7) by second plain radial bearing (6), second crank (7) is connected on the rotatingshaft of secondary valve by secondary valves connecting sleeve (8), and the output of electric device for valve (1) drives the keying of controlling this pair valve by second crank (7).
Technique scheme can further be improved to: this device also is provided with a core-regulating mechanism, described core-regulating mechanism comprises: also be with cylindrical hole selfaligning bearing (9) on secondary valve rotatingshaft and secondary valve connecting sleeve (8), selfaligning bearing (9) is outer to be with regulating center bearing base, and regulating center bearing base is cemented on the valve flanges.
The beneficial effects of the utility model are: only need by an electric device for valve, in valve of control, can also form control, especially for the control different medium, such as water and foam to another valve, switch and use, with a wide range of applications in fields such as fire-fightings.

Fig. 1 is the utility model overall structure schematic representation.
Fig. 2 is the utility model plan view.
Fig. 3 is the local figure in selfaligning bearing place.
Embodiment
The purpose of this utility model is: electric device for valve also forms control to another valve simultaneously by valve of control, i.e. interlock control.As shown in Figure 1, so the electric device for valve 1 that at first comprises of the present utility model, its output shaft is connected to coupling shaft by key, or itself carries a coupling shaft, by main valve connecting sleeve 2 this coupling shaft is connected with the rotatingshaft of main valve, thereby realizes of the control of this electric device for valve main valve.Simultaneously, first crank 3 is installed on the main valve connecting sleeve 2, has realized that electric device for valve 1 can export transmission when the control main valve opens and closes.First crank 3 is connected with connecting rod 5 again, the output transmission of Electric actuator 1 is continued to transmit, between first crank 3 and the connecting rod 5 is to be connected by first plain radial bearing 4, connecting rod 5 is connected in the connecting rod cover of first plain radial bearing 4, it not only can bear bigger load, also can make the transmission of electric device for valve 1 export accurate transfer.The other end at connecting rod 5 connects second crank 7 again by second plain radial bearing 6, second crank 7 is connected on the rotatingshaft of secondary valve by secondary valve connecting sleeve 8, and the electric device for valve output of being transmitted 5 to second cranks 7 by connecting rod drives the keying of controlling these pair valves by this second crank 7.
The utility model dual-valve linkage control gear can be controlled two valves and open and close simultaneously, and another was in closed condition when two one on valves were opened in the time of also controlling.This depends on when the utility model is installed the installation coupled condition to left and right sides crank and main valve and secondary valve rotatingshaft.The user can select as required voluntarily.As shown in Figure 2, then be that two valves of control open and close simultaneously.But for example in the fire-protection equipment field,, use the utility model then can realize especially controlling different medium in some field, use such as the switching of water and foam by two medium pipeline valves of this device control as the corollary equipment of fire-fighting monitor.
As shown in Figure 3, the utility model can also be provided with a core-regulating mechanism; Described core-regulating mechanism comprises: also be with cylindrical hole selfaligning bearing 9 on secondary valve rotatingshaft and secondary valve connecting sleeve 8, be with regulating center bearing base outside the selfaligning bearing 9, regulating center bearing base is cemented on the valve flanges.This core-regulating mechanism can be eliminated the not parallel error that causes after connecting rod and the crank installation, makes the bivalve motion steadily.
