Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, and more specifically to an energy-saving electromagnetic valve. Background Art

[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulic or pneumatic. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions in the control system. The most commonly used ones are check valves, safety valves, directional control valves, speed regulating valves, etc.

[0003] The solenoid valve of the prior art is shown in the accompanying drawings of the specification. Figure 1 As shown, the magnetic force after the coil is started drives the valve core to squeeze the spring to achieve the circulation of the medium. When the circulation of the medium needs to be stopped, the start of the coil only needs to be paused. After the magnetic force disappears, the elastic force of the spring will push the valve core back to its position; however, when the medium needs to flow, continuous power supply is required to maintain the open state, resulting in relatively large power consumption and high cost. Therefore, the present application proposes an energy-saving solenoid valve. Utility Model Content
