Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, in particular to a fast opening and closing electromagnetic valve. Background Art

[0002] A solenoid valve is a valve that uses electromagnetic principles to control the flow of fluid. Its main structure consists of an electromagnetic coil, a valve core, and a valve body. When the electromagnetic coil is energized, it generates a magnetic field, which attracts the valve core to move. The movement of the valve core is used to control the opening or closing of the valve channel.

[0003] After searching, the Chinese application number CN202021695627.0 proposes a new type of quick opening and closing solenoid valve, including a pipe, a mounting seat, a solenoid valve body, a slide groove, a first telescopic rod, a slider, a cavity, a fixing mechanism, an insert and a slot, the midpoint of the top of the pipe is movably connected to the mounting seat, the midpoint of the top of the mounting seat is fixedly connected to the solenoid valve body, the top of the pipe and on the left and right sides of the mounting seat are provided with slide grooves, the inner wall of the slide groove is fixedly connected to the first telescopic rod on the side away from the mounting seat, and the first telescopic rod is fixedly connected to the side close to the mounting seat, and the slider is slidably connected to the slide groove. In the above-mentioned prior art, the pipe, the mounting seat, the solenoid valve body, the slide groove, the first telescopic rod, the slider, the cavity, the fixing mechanism, the insert and the slot are matched with each other, so that the solenoid valve can be quickly disassembled and assembled, thereby facilitating subsequent maintenance.

[0004] However, during the use of the solenoid valve, the opening and closing speed of the valve will be affected by the strength of the magnetic field and the purity of the liquid. When the liquid contains a large amount of impurities, the impurities will adhere to the valve. Long-term accumulation and adhesion will increase the valve's own gravity and the resistance during movement, thereby reducing the valve opening and closing speed and affecting the control accuracy. For this reason, a fast opening and closing solenoid valve is proposed. Utility Model Content
