Description
Technical Field
[0001] The utility model relates to the field of electromagnetic pulse valves, in particular to a control structure of an electromagnetic pulse valve. Background Art
[0002] The electromagnetic pulse valve is a valve that generates magnetic force through electric current to control the opening and closing of the valve core. Figure 1 The current electromagnetic pulse valve control method is a dual-line control method. Multiple pulse valves are connected through a controller. There is a dual-line connection between each pulse valve and the controller to form a loop. The controller is integrated with a power supply, and the dual lines connecting the pulse valves are respectively connected to the positive and negative poles of the power supply.
[0003] An electronic switch is installed between each electromagnetic pulse valve and the controller circuit. The control signal of the electronic switch is a voltage signal. By controlling the on-off of the electronic switch, the circuit between the controller and the pulse valve is controlled, thereby controlling the opening and closing of the pulse valve.
[0004] The aforementioned solenoid pulse valve control structure utilizes a two-wire connection between the controller and the individual solenoid pulse valves, resulting in time-consuming and costly wiring. The connecting wires, which power the solenoid pulse valves, require large, costly wires. Furthermore, in actual use, the distance between the controller and the solenoid pulse valves is considerable, resulting in long connecting wires and significant voltage losses. This can lead to insufficient voltage supply to the solenoid pulse valves, preventing the valves from opening. Summary of the Invention
[0005] In order to solve the defects of the control structure of the electromagnetic pulse valve in the prior art, the utility model provides a control structure of the electromagnetic pulse valve, which can effectively reduce the cost of connecting wires and reduce the influence of voltage line loss on the opening and closing control of the electromagnetic pulse valve.
[0006] The above technical objectives of the present invention are achieved through the following technical solutions:
[0007] The utility model provides a control structure of an electromagnetic pulse valve, the control structure comprising a controller, a power supply, an electronic switch and an electromagnetic pulse valve, wherein the distance between the power supply and the electromagnetic pulse valve is smaller than the distance between the controller and the electromagnetic pulse valve, and the coil of the electromagnetic pulse valve is connected to the electrode of the power supply via a power line;
[0008] The electronic switch is connected in series between the coil of the electromagnetic pulse valve and the power supply, and is used to control the on / off of the circuit between the power supply and the electromagnetic pulse valve; the controller is connected to the control end of the electronic switch through a signal output line, and the controller inputs a control signal to the electronic switch to control the electronic switch to open or close.
[0009] Furthermore, there are at least two electromagnetic pulse valves, the coils of all the electromagnetic pulse valves are connected to the power supply, and each of the coils of the electromagnetic pulse valves is connected to an electronic switch in the circuit connecting the power supply, and the controller is connected to the electronic switches one by one through signal output lines with the same number as the electronic switches.
[0010] Furthermore, the electronic switch is arranged on the electromagnetic pulse valve.
[0011] Furthermore, the electronic switch is a field effect tube, the drain and source of the electronic switch are respectively connected to the coil of the electromagnetic pulse valve and the power supply, and the gate of the electronic switch is connected to the controller through the signal output line.
[0012] Furthermore, the power supply is a DC24V power supply, the control signal is a voltage signal output by the controller to the electronic switch through the signal output line, and the effective voltage signal of the electronic switch is DC5-20V.
[0013] Furthermore, the voltage signal is DC20V.
[0014] Furthermore, the closest distance between the power supply and the electromagnetic pulse valve does not exceed 2 meters.
[0015] Furthermore, the number of the power supply is one, and the coils of all the electromagnetic pulse valves are connected in parallel to the same power supply.
[0016] Furthermore, the control structure further includes a short-circuit wire, to which a load resistor is connected, and the short-circuit wire is detachably connected between the positive electrode of the power supply and the control end of the electronic switch.
[0017] In summary, the present invention has the following beneficial effects:
[0018] 1. In the control structure of the electromagnetic pulse valve of the present invention, the electromagnetic pulse valve is powered independently by a power supply, so that the setting of the power supply is not limited by the setting position of the controller, and the distance between the power supply and the electromagnetic pulse valve is smaller than the distance between the controller and the electromagnetic pulse valve. Compared with the prior art in which the electromagnetic pulse valve is powered directly by the controller, the independent power supply can reduce the length of the power cord, reduce the cost of the wires, and reduce the voltage loss on the power cord, ensuring that the electromagnetic pulse valve can be opened and closed normally; the electronic switch is connected to the controller via a single wire (signal output wire), reducing the total length of the connecting wire between the controller and the electronic switch; at the same time, the signal output wire is only used for the controller to output the control signal, and no large current is generated in it. Even if there is voltage loss in the signal output wire, it is not easy to affect the normal use of the electronic switch, thereby reducing the diameter of the connecting wire between the controller and the electronic switch, which can effectively reduce costs.
[0019] 2. When at least two electromagnetic pulse valves are set, an electronic switch is set in the circuit of each electromagnetic pulse valve. The controller is connected to each electronic switch one by one. The operator can control the on and off of each electronic switch at the controller to control the opening and closing of each electromagnetic pulse valve.
[0020] 3. The electronic switch is set on the electromagnetic pulse valve to reduce the distance between the electronic switch and the coil of the electromagnetic pulse valve, further reducing the length of the power line in the loop connecting the electromagnetic pulse valve and the power supply, thereby further saving costs and reducing voltage line loss.
[0021] 4. The electronic switch is a field effect tube, which is connected in series between the electromagnetic pulse valve coil and the power supply. The controller inputs a 20V voltage signal to the gate to control it. The electronic switch can be normally turned on within DC5-20V, so even if there is a voltage line loss on the signal output line, it will not affect the normal opening of the electronic switch.
[0022] 5. The electronic switch control terminal is short-circuited with the positive pole of the power supply through a short-circuit wire. A load resistor is connected in series with the short-circuit wire to adjust the voltage of the electronic switch control terminal to within the set range. In this way, the electromagnetic pulse valve can be opened and closed even when the controller is not operated. This allows on-site testing of whether the electromagnetic pulse valve is working properly, facilitating installation and commissioning, and diagnosing pulse valve faults. After the test is completed, the short-circuit wire is removed from the control terminal of the electronic switch without affecting the normal operation of the electronic switch.

[0028] The present invention will be further described below with reference to the accompanying drawings.
[0029] This embodiment provides a control structure 1000 of an electromagnetic pulse valve, referring to Figure 2 A control structure 1000 for an electromagnetic pulse valve includes a controller 100, a power supply 200, an electronic switch 300, and an electromagnetic pulse valve 400. The power supply 200 is connected to the electromagnetic pulse valve 400 to supply power to the electromagnetic pulse valve 400, thereby driving the electromagnetic pulse valve 400 to open or close. The electronic switch 300 is connected in series between the coil 410 of the electromagnetic pulse valve 400 and the power supply 200, and is used to control the on / off of the circuit between the power supply 200 and the electromagnetic pulse valve 400. The controller 100 is connected to the electronic switch 300 via a signal output line 600, and the controller 100 inputs a control signal to the electronic switch 300 to control the opening or closing of the electronic switch 300.
[0030] The power supply 200 has a positive electrode and a negative electrode. One end of the coil 410 of the electromagnetic pulse valve 400 is connected to the positive electrode of the power supply 200 via a power cord 500, and the other end of the coil 410 is connected to the power supply 200 via another power cord 500. Thus, the electromagnetic pulse valve 400 and the power supply 200 are connected to form a circuit. When the power supply 200 and the coil 410 are connected, voltage is provided to the coil 410. The current flowing through the coil 410 generates an electromagnetic force, which drives the valve core of the electromagnetic pulse valve 400 to move and open the electromagnetic pulse valve 400. When the power supply 200 is disconnected, the electromagnetic force of the coil 410 disappears, and the valve core of the electromagnetic pulse valve 400 returns to its original position, closing the electromagnetic pulse valve 400.
[0031] In this embodiment, the power supply 200 and the controller 100 are independently provided, so that the setting of the power supply 200 is not limited by the setting position of the controller 100. Specifically, the distance between the power supply 200 and the electromagnetic pulse valve 400 is less than the distance between the controller 100 and the electromagnetic pulse valve 400. In the prior art, the electromagnetic pulse valve 400 is powered directly by the controller 100. Since the controller 100 is far away from the electromagnetic pulse valve 400, the length of the connecting line from the controller 100 to the electromagnetic pulse valve 400 is relatively long. In this embodiment, the independent power supply 200 can reduce the length of the power cord 500, reduce the cost of the wires, and reduce the voltage loss on the power cord 500, thereby ensuring that the voltage of the power supply 200 can normally drive the electromagnetic pulse valve 400 to open.
[0032] The power supply 200 is arranged close to the electromagnetic pulse valve 400. Specifically in this embodiment, the distance between the power supply 200 and the electromagnetic pulse valve 400 is no more than 2 meters to ensure that the power line 500 between the power supply 200 and the electromagnetic pulse valve 400 is short.
[0033] In this embodiment, the power supply 200 is a DC 24 V power supply. In other embodiments, other suitable power supplies may be selected according to the actual voltage requirements of the electromagnetic pulse valve 400.
[0034] In this embodiment, the electromagnetic pulse valve 400 is provided with at least two, Figure 2 Specifically, two electromagnetic pulse valves 400 are provided. The coils 410 of all electromagnetic pulse valves 400 are connected to the power supply 200. An electronic switch 300 is connected in series in the circuit connecting the coil 410 of each electromagnetic pulse valve 400 and the power supply 200. The controller 100 is connected to each electronic switch 300 via the same number of signal output lines 600 as the number of electronic switches 300. The operator at the controller 100 can control the on / off of each electronic switch 300, thereby controlling the opening and closing of each electromagnetic pulse valve 400.
[0035] In addition, in other embodiments, only one electromagnetic pulse valve 400 may be provided.
[0036] In this embodiment, only one power supply 200 is provided, and the coils 410 of all electromagnetic pulse valves 400 are connected in parallel to the same power supply 200 to reduce the cost of the power supply 200. In other embodiments, when there are a large number of electromagnetic pulse valves 400 or the electromagnetic pulse valves 400 are spaced far apart, two or more power supplies 200 may be provided to power different electromagnetic pulse valves 400 to reduce voltage line losses caused by excessively long power cords 500.
[0037] The controller 100 inputs a control signal to the electronic switch 300 via a signal output line 600 to control the opening or closing of the electronic switch 300, thereby switching the on / off state of the circuit between the electromagnetic pulse valve 400 and the power supply 200, thereby controlling the opening and closing of the electromagnetic pulse valve 400. Each electronic switch 300 is connected to the controller 100 via a single signal output line 600. Compared to the prior art method of connecting the electronic switch 300 and the controller 100 via a double-connection wiring connection, the total length of the connection line between the controller 100 and the electronic switch 300 is reduced. Furthermore, the signal output line 600 only outputs signals from the controller 100 and does not need to power the coil 410 of the electromagnetic pulse valve 400. This prevents high current from flowing within the signal output line 600. Even if voltage loss occurs in the signal output line 600, it is unlikely to affect the normal operation of the electronic switch 300. This reduces the diameter of the signal output line 600, effectively reducing costs.
[0038] In this embodiment, the electronic switch 300 is arranged on the electromagnetic pulse valve 400 to reduce the distance between the electronic switch 300 and the coil 410 of the electromagnetic pulse valve 400, further reducing the length of the power cord 500 in the loop connecting the electromagnetic pulse valve 400 and the power supply 200, further saving the cost of the power cord 500 and reducing the voltage line loss on the power cord 500.
[0039] In this embodiment, the electronic switch 300 is a field effect transistor having a source, a drain, and a gate. The drain and source of the electronic switch 300 are respectively connected between the coil 410 of the electromagnetic pulse valve 400 and the electrodes of the power supply 200. The gate of the electronic switch 300 is connected to the controller 100 via a signal output line 600.
[0040] The controller 100 can output a voltage signal to the electronic switch 300 via the signal output line 600, which serves as a control signal to control the on / off of the electronic switch 300. Specifically, the effective gate voltage signal of the electronic switch 300 is DC5-20V. The controller 100 inputs a DC20V voltage signal to the gate of the electronic switch 300. Even if voltage line loss occurs in the voltage signal, the voltage signal received by the electronic switch 300 can remain within the DC5-20V range, ensuring continuity between the source and drain, without affecting the normal operation of the electronic switch 300.
[0041] In addition, in other embodiments, the gate voltage and the voltage signal of the electronic switch 300 may also be other voltage values, as long as the electronic switch 300 can be turned on after the controller 100 sends the voltage signal.
[0042] In other embodiments, the electronic switch 300 may also be other suitable electrically controlled switches.
[0043] Reference Figure 3In this embodiment, the electronic switch 300 and the positive pole of the power supply 200 can be connected via a short-circuit wire 700, to which a load resistor 800 is connected. The short-circuit wire 700 is detachably connected between the positive pole of the power supply 200 and the control terminal (i.e., the gate) of the electronic switch 300. Thus, when the controller 100 is not in operation, a voltage signal can be provided by the power supply 200. The load resistor 800 reduces the 24V voltage signal to the 5-20V operating voltage signal range of the electronic switch 300 to control the opening of the electronic switch 300 and realize the opening and closing of the electromagnetic pulse valve 400. This allows on-site testing of whether the electromagnetic pulse valve 400 is operating properly, facilitating installation, commissioning, and diagnosis of pulse valve faults. After the on-site inspection is completed, the short-circuit wire 700 is removed from the control terminal of the electronic switch 300 so as not to affect the normal operation of the electronic switch 300.
[0044] In this embodiment, the control terminal of the electronic switch 300 is short-circuited with the positive terminal of the power supply 200 on the electromagnetic pulse valve 400 via a shorting wire 700. This reduces the length of the shorting wire 700. The shorting wire 700 and the electromagnetic pulse valve 400 can share a connection terminal, saving costs. In other embodiments, the electronic switch 300 can also be short-circuited with the positive terminal of the power supply 200 at other locations on the power cord 500 via the shorting wire 700.
[0045] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
