Description

Technical Field

[0001] The present invention relates to an improvement of a solenoid valve, especially a power-saving and modular solenoid valve and its driving method. Background Art

[0002] At present, for commercially available assembled solenoid valves, due to the energy consumption ratio problem, in applications that require long-term continuous opening, the power consumed during operation is relatively high, so the energy consumption cost is also relatively higher. Therefore, if it is applied in places where power supply is lacking, it has certain problems to maintain normal operation.

[0003] The commercially available power-saving solenoid valve has the advantage that it can save energy to the greatest extent during the operation process, thereby reducing the operating cost of the overall system. For example, low-power electronic components and power-saving control circuits are used to ensure high efficiency during opening and closing, so the service life of the overall parts can also be improved.

[0004] Therefore, if the aforementioned assembled solenoid valve can have the characteristics of energy saving, it can effectively improve the problem of power demand and thus increase the service life. Summary of the Invention

[0028] A series control module 20, which is composed of a series control circuit 21 respectively connected to two full-wave rectifiers 22, and then the full-wave rectifiers 22 are respectively connected to two current-limiting hold switches 23. Among them, the current-limiting hold switches 23 are respectively connected to the solenoid valves 11. It can be seen from Figure 3 , after the series control circuit 21 is connected to the corresponding series control circuit 21 and then continues to be connected, more quantities can be continued to be connected in series, and finally a series control module 20 is formed. Each solenoid valve 11 therein will have an independent code and position, so even for complex operations, the target can be easily specified to perform relevant actions and instructions;

[0029] A power supply switching unit 30, connected to the series control module 20. By means of the power supply switching unit 30, the pneumatic circuit logic setting of the series control module 20 can be turned on or off.

[0030] The main function of the aforementioned full-wave rectifier 22 is to convert the AC voltage into a DC voltage for use, which can ensure that it operates with a constant positive DC voltage during use. Conventional solenoid valves often need to be produced in corresponding models to match the control methods of NPN (NPN Transistor) and PNP (PNP Transistor), making the production line complex. Moreover, it can take the opportunity to improve the problems of conventional solenoid valves.

[0031] The following will further illustrate the usage process of the embodiments of the present invention. The main steps include: a solenoid valve power-saving step. Through the output of the full-wave rectifier 22 and the current-limiting holding switch 23 and the control of the power supply switching unit 30, the power-saving control of the pneumatic solenoid valve module 10 can be fully realized.

[0032] A solenoid valve modularization step. The pneumatic solenoid valve module 10 is composed of two solenoid valves 11. The pneumatic solenoid valve module 10 is used for external pneumatic circuit control. It is connected to the full-wave rectifier 22 through the series control circuit 21 and then connected to the current-limiting holding switch 23 to form the series control module 20. This structure can help the solenoid valve 11 obtain more efficient control.

[0033] A driving and using step. This system allows multiple solenoid valves 11 to be connected in series and operated in a modular manner, which is effective for complex pneumatic circuit control applications.
