The valve core 2 comprises a blocking surface 211, the force direction of the blocking surface 211 points to the first magnetic force element 6, when the valve is in a sealing state, fluid in the valve body 1 generates pressure on the valve core 2, when the pressure is overlarge, the pressure of the fluid can enable the valve core 2 to generate extrusion deformation, the reliability of the valve driving device is influenced, the blocking surface 211 can guide the pressure of the fluid in the valve body 1, the pressure is transferred to a position with stronger compressive strength of the valve core 2, the reliability of the valve core 2 in use is improved, when the force direction of the blocking surface 211 points to the first magnetic force element 6, the pressure of the fluid on the valve body 1 can be transferred to the first magnetic force element 6, and the first magnetic force element 6 can receive the pressure of the fluid in real time; one end of the valve core 2 is fixedly connected with one side of the first magnetic member 6, so that the first magnetic member 6 is prevented from falling off from the valve core 2, and the action of driving the valve can be smoothly finished; the second magnetic member 5 is fixedly connected with the valve body 1, so that the second magnetic member 5 is prevented from falling off due to external force, the failure of the valve driving device is prevented, and potential safety hazards are generated; the magnetic pole of the first magnetic member 6 is the same as the magnetic pole of the second magnetic member 5, the magnetic force between the first magnetic member 6 and the second magnetic member 5 comprises repulsion and attraction, the repulsion or attraction in the magnetic field and the pressure of the fluid in the valve body 1 on the valve core 2 are balanced, so that the valve core 2 is always kept at the corresponding position of the valve body 1, when the valve core 2 is subjected to the excessive pressure of the fluid, the pressure breaks the mutual balance between the repulsion or attraction and the valve body 1, the fluid under pressure passes through the valve body 1 in a short time, the balance state of the repulsion or attraction and the valve body 1 is continuously ensured, the situation that the valve is damaged due to the fact that the pressure in the valve exceeds a set value is prevented, meanwhile, the core parts of the valve driving are the first magnetic member 6 and the second magnetic member 5, no other parts exist between the first magnetic member 6 and the second magnetic member 5, and the rusting probability of parts in the valve driving device is prevented from being increased, meanwhile, the maintenance is convenient, and the sealing performance is good; the other side of the first magnetic member 6 corresponds to the second magnetic member 5, so that the use efficiency of the magnetic field between the first magnetic member 6 and the second magnetic member 5 is maximized, and the cost increase caused by the waste of magnetic force is prevented; a gap is formed between the first magnetic member 6 and the second magnetic member 5, so that sufficient spatial displacement of the first magnetic member 6 is ensured, and the first magnetic member 6 is prevented from being too tight to displace the first magnetic member 6, so that the valve driving action cannot be realized.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
