Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the patent of the present invention.

[0029] figure 1 and figure 2It is two commonly used three-terminal valves controlled by electrical signals. The port 16 of the valve 10 can communicate with the port 12 or 14 through electronic control. When the ports 16 and 12 are connected, the ports 16 and 14 are automatically closed. Conversely, if ports 16 and 14 are connected, ports 16 and 12 are automatically turned off. Similarly, the port 22 of the valve 20 can be connected to the port 24 or 26 through electronic control. When the ports 22 and 24 are connected, the ports 22 and 26 are automatically closed. Conversely, if ports 22 and 26 are connected, ports 22 and 24 are automatically turned off.
