In one embodiment, the present invention provides a multi-set multi-way valve combination control system, which comprises a hydraulic driving device 100, a control device 200 and N sets of electric proportional multi-way valves 300.
Wherein, N groups of the electrically proportional multi-way valves 300 are respectively connected with the corresponding hydraulic driving devices 100, and N is a positive integer greater than 2. The hydraulic driving device 100 may be a hydraulic motor or a hydraulic cylinder, and for driving, each pair of the electric proportional multi-way valves 300 is correspondingly connected to the hydraulic driving device 100. For the structure of the electric proportional multi-way valve 300 and the connection between each pair of the electric proportional multi-way valve and the hydraulic driving device 100, please refer to the prior art, which is not further described herein.
The control device 200 is electrically connected to each of the electric proportional multi-way valves 300, respectively, to output a control signal to each of the proportional multi-way valves. The control box can be adopted in the specific control device 200, and the structure is simple.

The control device 200 and each electric proportional multi-way valve 300 can also adopt wireless connection, namely remote control, so as to achieve the purpose of remote control. The control circuit structure in the specific control device 200 may be designed according to specific control logic, and is not limited herein.
The N groups of electric proportional multi-way valves 300 respectively receive the control signals output by the control device 200 and correspondingly control the hydraulic driving device 100 to act according to the control signals, for example, control the corresponding linkage of the corresponding electric proportional multi-way valve 300 to perform corresponding actions. The number of the sets of the electric proportional multi-way valves 300 may be the same or different, and may be set as needed.
By applying the multi-set multi-way valve combined control system provided by the invention, each set of the electric proportional multi-way valve 300 respectively receives the control signal output by the control device 200, and then controls the hydraulic drive device 100 to execute the action of the element liquid according to the requirement of the control signal. By jointly controlling a plurality of groups of multi-way valves, the use of a plurality of control boxes is avoided, and the requirement of remote operation equipment can be met. One person can simultaneously control a plurality of groups of multi-way valves through the multi-group multi-way valve combined control system, and further the number of personnel is reduced. An operator can operate the control device 200 in a visual field range without staying beside each operating valve to complete operation, and the operation is simpler, more flexible and safer.
Specifically, the control device 200 is provided with i working port selection components 201, each working port selection component 201 corresponds to a working port of a different bank of the electric proportional multi-way valve 300, and each working port selection component 201 includes a first working position and a second working position corresponding to a first working port and a second working port of the corresponding bank, respectively, when the working port selection component 201 selects the first working position, the first working port works, the second working port is closed, when the working port selection component 201 selects the second working position, the second working port works, the first working port is closed, wherein i is a positive integer greater than 2. That is, the control device 200 is provided with i working port selection components 201, and the number of the specific working port selection components 201 can be set according to the number of the banks of the electric proportional multi-way valve 300. The working port selecting part 201 is used for selecting a working port corresponding to a certain bank of the electric proportional multi-way valve 300, and the working port is a first working port and a second working port. Each working port selecting component 201 comprises a first working position and a second working position, when the working port selecting component 201 selects the first working position, the corresponding first working port works, the second working port is closed, when the working port selecting component 201 selects the second working position, the corresponding second working port works, and the first working port is closed. Specifically, the first working gear of each pair correspondingly controls the electromagnet of the first working port of the pair, and the second working gear of each pair correspondingly controls the electromagnet of the second working port of the pair. Preferably, the first operating gear and the second operating gear are mutually exclusive, that is, the first operating gear and the second operating gear cannot be selected simultaneously, that is, when the first operating gear is selected, the second operating gear must be reset; when the second operating range is selected, the first operating range must be reset, which may be implemented by control logic. The corresponding connection and switching of the specific working gear and the working port can be realized through a control circuit.
In order to facilitate the speed control of the electric proportional multi-way valve 300, j speed adjusting components 202 are arranged on the control device 200, each speed adjusting component 202 corresponds to a different bank of the electric proportional multi-way valve 300 respectively and is used for increasing or decreasing the control current of the corresponding bank, wherein j is a positive integer greater than 2. That is, j speed adjustment components 202 are provided on the control device 200, and the number of the speed adjustment components 202 can be set according to the number of the banks of the electric proportional multi-way valve 300. The speed adjusting unit 202 adjusts the flow rate of each bank of the electric proportional multi-way valve 300. The particular speed adjustment component 202 and associated control current adjustment may be implemented by a control circuit.
Specifically, each speed adjusting part 202 includes an increase button for increasing the control current of the corresponding link by a first preset value when the increase button is pressed, and a decrease button for decreasing the control current of the corresponding link by a second preset value when the decrease button is pressed. That is, the control current of the electric proportional multi-way valve 300 is increased or decreased by increasing the key "+" and decreasing the key "-" respectively, so as to adjust the working flow of each unit. The speed adjusting part 202 adopts a key, so that the structure is simple and the operation is convenient. The structure of knob can be adopted according to the requirement. The specific first preset value and the second preset value can be the same or different in size.
On the basis of the above embodiments, the control device 200 is provided with the gear position adjusting component 203, the gear position adjusting component 203 is electrically connected with the working port selecting component 201 and the speed adjusting component 202 respectively, the gear position adjusting component 203 comprises a zero gear and a plurality of functional gears respectively corresponding to different electric proportional multi-way valves 300, when the gear position adjusting component 203 is set in the zero gear, the control device 200 does not select each electric proportional multi-way valve 300, when the gear position adjusting component 203 is set in each functional gear, the control device 200 selects the corresponding electric proportional multi-way valve 300, the gear position adjusting component 203 is used for adjusting the working ports of different selected couples of the electric proportional multi-way valve 300, and the speed adjusting component 202 is used for adjusting the control current of the different selected couples of the electric proportional multi-way valve 300.
That is, the gear position adjusting part 203 is the selectively operated electric proportional multi-way valve 300, which is composed of a plurality of gear positions, a zero gear indicates that no electric proportional multi-way valve 300 is selected, and the rest of the function gears correspondingly select different electric proportional multi-way valves 300. When the gear adjusting part 203 is set to zero gear, the working opening selecting part 201 and the speed adjusting part 202 are disabled; when the shift position adjusting member 203 is set to each functional position, it indicates that the corresponding electric proportional multi-way valve 300 is selected, the corresponding working port selecting member 201 selects the working port of each bank of the electric proportional multi-way valve 300, and each speed adjusting member 202 adjusts the magnitude of the control current of each bank of the electric proportional multi-way valve 300. By arranging the gear position adjusting component 203, the electric proportional multi-way valve 300 controlled by each working port selecting component 201 and the speed adjusting component 202 can be switched, so that the working port selecting component 201 and the speed adjusting component 202 do not need to be arranged corresponding to each electric proportional multi-way valve 300, the structure is obviously simplified, and the operation of an operator is facilitated. Of course, in order to effectively control each bank of the electric proportional multi-way valve 300, the i and the j should be larger than the maximum bank number of the electric proportional multi-way valve 300.
Specifically, the gear adjusting component 203 is a gear adjusting knob. Namely, the gear switching is realized through the knob, and the structure is simple. The gear can be switched by a key or the like according to requirements. The specific correspondence between each gear and each electric proportional multi-way valve 300 can be realized through a control circuit.
Further, the gear position adjusting part 203 includes three functional gears corresponding to three different electric proportional multi-way valves 300, respectively. The gear adjusting part 203 of each control system comprises three functional gears, and three different electric proportional multi-way valves 300 are correspondingly controlled. When the number of the electric proportional multi-way valves 300 is more than three, the control can be realized by a plurality of control devices 200. The three function gears are arranged, so that the simultaneous control of the multiple groups of electric proportional multi-way valves 300 is realized, and the workload of operators is considered. For convenience of description, three function files are provided as an example. The three functional gears are the first gear, the second gear and the third gear, the first gear controls the first electric proportional multi-way valve 300 correspondingly, the second gear controls the second electric proportional multi-way valve 300 correspondingly, and the third gear controls the third electric proportional multi-way valve 300 correspondingly.
When the first gear is selected by the gear position adjusting part 203, it means that the flow rate of each of the working ports of the first electro proportional multi-way valve 300 can be controlled by the speed adjusting part 202 at this time, and whether the working port of each of the banks of the first electro proportional multi-way valve 300 is the first working port or the second working port can be selected by the working port selecting part 201. As shown in FIG. 1, the maximum union of the first, second and third electrically proportional multi-way valves 300, 300 and 300 is designated as m-union, where m is a positive integer greater than 2. The speed adjusting component 202 includes m groups, each group includes an increase button and a decrease button, and the flow of the working ports of the respective groups is adjusted correspondingly. The working port selecting part 201 is correspondingly provided with m groups, each group includes a first working gear a and a second working gear B, that is, a first working gear A1 and a second working gear B1 are provided corresponding to the first couple, a first working gear A2 and a second working gear B2 are provided corresponding to the second couple, and so on, a first working gear Am and a second working gear Bm are provided corresponding to the m couples to respectively set the working ports of the respective couples.
The control device 200 is further provided with a locking and unlocking member 204, and the locking and unlocking member 204 is used for locking or unlocking the current selection of the gear position adjusting member 203 according to requirements. That is, the control device 200 further has a lock/release function of locking or releasing the control state of the currently selected electric proportional multi-way valve 300, the locking indicating that the electric proportional multi-way valve 300 is kept in the existing state, and the releasing indicating that the control state of the electric proportional multi-way valve 300 can be adjusted. For example, when any one of the first, second, and third electric proportional multi-way valves 300, 300 is selected by the shift position adjusting part 203, the state of the output of the present electric proportional multi-way valve 300 may be locked or unlocked by the lock/unlock function. The lockout indicates the selected state of the lockout working port selection unit 201 and the magnitude of the current for all selected working ports of the electro-proportional multi-way valve 300; the unlocking indicates that the lockout limit can be released and the current level of the selected working port and working port of the electro-proportional multi-way valve 300 can be adjusted again. Preferably, when the other electric proportional multi-way valve 300 is to be controlled, the current of the selected working port of the current multi-way valve is firstly locked, so that the working current of the current multi-way valve is automatically zero when the other multi-way valve is switched.
In the case where the lock/unlock member 204 is provided, the lock/unlock member 204 is aged when the zero range is selected by the range adjusting member 203.
In addition to the above embodiments, the control device 200 is further provided with an emergency control unit 205, and when the emergency control unit 205 is activated, the total power supply of the equipment having the electric proportional multi-way valve 300 is cut off. That is, the control device 200 also has an emergency function, when the emergency control part 205 is activated, the total power of the equipment can be cut off, and thus the equipment stops all operations to cope with the emergency state occurred. In the case where the lock/unlock member 204 is provided, when the gear position adjusting member 203 selects the zero gear position, only the emergency control member 205 is available, that is, the electric proportional multi-way valve 300 controlled by the control device 200 has no output, and the electric proportional multi-way valve 300 having the output is also stopped. Specifically, the corresponding functions of the emergency control component 205 and the locking/unlocking component 204 can be realized by corresponding control circuits.
