According to the invention, under the action of spring force and electromagnetic force, the fluid pressure is regulated and controlled in a biphase manner, so that the accurate regulation and control of the fluid pressure are realized.
Specifically, sealing rings are arranged between the valve core body 41 and the pressure ring 3, between the pressure ring 3 and the pressure regulating cavity and between the electromagnetic induction coil 2 and the electromagnetic cavity, so that the sealing effect is ensured.
In order to further optimize the technical scheme of the invention, the sealing surface of the valve core body 41, which is contacted with the valve core cavity, is a spherical surface, so that the sealing performance is improved.
In order to further optimize the technical scheme of the invention, one side of the valve core body 41 close to the spherical surface is provided with a crown surface 411, and the size of the crown surface 411 is larger than that of a movable sealing surface on the right side of the valve core body, so that double closing force is provided for valve closing through pressure difference generated by the spring 9 and the crown surface 411, and the closing effect is ensured.
The working principle of the invention is as follows:
when the flow rate is regulated, the pressure sensor 5 transmits the measured pressure signal to the electromagnetic induction coil 2 through converting the signal into current, a repulsive force is generated between the electromagnetic induction coil 2 and the permanent magnet 42, so that the valve core 41 reaches a balance under the combined action of the elasticity of the spring 9 and the electromagnetic induction force, the opening corresponding to the inflow pressure is the opening required by the system, when the inflow pressure changes to influence the pressure change in the system, the current signal is given to the electromagnetic induction coil 2 according to the signal measured by the pressure sensor 5, and the valve core 4 reaches a new opening again under the balance of new electromagnetic force and spring force, thereby realizing the regulation of the flow rate.
