Abstract

The invention discloses a permanent magnet electromagnetic valve. The valve comprises a valve body and a permanent magnet valve core in the valve body, wherein a left sealing gasket and a right sealing gasket are fixed at the two ends of the valve core, an iron core is connected to the valve body, a sealing ring is connected between the valve body and the iron core, the iron core is wound with a coil, and an iron cover is connected with the iron core and the valve body and is used for fixing the iron core; when the coil is electrified, the iron core generates a magnetic pole repulsive to the permanent magnet valve core, the valve core is pushed to move leftwards under the repulsive force to seal the valve port of the valve body, and the right valve port is opened; and when the coil is notelectrified, the magnetic pole of the iron core disappears, the permanent magnet valve core moves rightwards under the action of self-magnetic force to seal the valve port of the iron core, and meanwhile, the left valve port is opened. According to the valve, a spring of a common electromagnetic valve is removed, so that the novel electromagnetic valve is simple in structure, stable and reliable.

Description

technical field [0001] The invention relates to a valve, in particular to an electromagnetic valve. Background technique [0002] Solenoid valves use energized coils to generate electromagnetic force to drive the valve core to open or close the valve and change the flow direction of the fluid. Solenoid valves are widely used in automatic control and remote control of fluids. In ordinary solenoid valves, a reaction spring is usually provided. Its structure is relatively complicated, the force is small, the stability is poor, the life is short, and it is prone to failure during use. In particular, the structure of the solenoid valve used in the control of some highly corrosive, flammable, and explosive fluids is more complicated. Contents of the invention [0003] In order to fundamentally overcome the shortcomings of traditional solenoid valves such as complex structure, poor stability, small force, and short life, [0004] The invention provides a novel electromagnetic...
