Control valve

A control valve, comprising:

• a valve core mechanism, and
• a trigger mechanism,
• wherein the valve core mechanism comprises:
• a valve body, wherein an active valve cavity is arranged inside the valve body;
• and
• an active valve core, wherein the active valve core is arranged in the active valve cavity and is movable along the active valve cavity, the active valve core has a first position and a second position respectively located at two ends of a movement stroke;
• after the active valve core is subjected to a first trigger force and switched from the second position to the first position, the active valve core directly or indirectly opens/closes a controlled port;
• and after the active valve core is subjected to a second trigger force opposite to the first trigger force and switched from the first position to the second position, the active valve core directly or indirectly closes/opens the controlled port;
• the trigger mechanism is configured to provide the first trigger force for switching the active valve core from the second position to the first position and to provide the second trigger force for switching the active valve core from the first position to the second position;
• an active magnet is arranged on the active valve core;
• and
• a positioning magnet is arranged on the valve body, the positioning magnet is adjacent to the active magnet, and the positioning magnet through a magnetic force interaction with the active magnet, enables the active valve core to have an acting force capable of maintaining the active valve core at a switched position after switching to the first position or the second position.
