The working principle and the specific embodiment of the invention are as follows:
working principle: the invention aims to control the opening and closing states of the ball valve by combining the electromagnetic action and the flow regulation characteristics possessed by the ball valve and controlling the opening and closing states of the ball valve through the electrifying state or not of the electrifying coils I5 in different directions and controlling the attraction strength of the annular moving magnet 18 by controlling the current strength in the electrifying coil II 16, thereby being convenient for controlling the sealing strength of the annular moving magnet 18 to the sealing ring II 23, and combining the fluid states of the water outlet 7 with the internal current strengths of different electrifying coils I5, namely, the different attraction degrees of the strip-shaped strong magnet, so that the fluid pressure of the water outlet 7 can be stabilized in different levels. The valve rod is arranged in the valve body, so that the sealing strength of the ball valve in the opening and closing state is flexibly controlled, and the moment required by the rotation of the valve core when the ball valve is opened can be obviously reduced.
Specific examples:
as shown in fig. 5, when the coil A, C is energized, the coil B, D is not energized, the coil A, C generates corresponding magnetic fields respectively, and attracts the S and N poles of the strip-shaped strong magnet 3 respectively, so that the strip-shaped strong magnet 3 rotates in the linear direction of the coil A, C, the strip-shaped strong magnet 3 drives the valve core 8 to rotate in the water flow moving direction through the upper and lower valve rods, and the ball valve is in an open state at this time;
as shown in fig. 6, when the coil B, D is energized, the coil A, C is not energized, the coil B, D generates corresponding magnetic fields respectively to attract the S and N poles of the strip-shaped strong magnet 3 respectively, so that the strip-shaped strong magnet 3 rotates in the linear direction of the coil B, D, the strip-shaped strong magnet 3 drives the valve core 8 to rotate in the vertical direction of water flow movement through the upper valve rod and the lower valve rod, the ball valve is in a closed state at this moment, and simultaneously, the energized coil ii 16 is energized to push the annular moving magnet 18 to move towards the sealing ring ii 23, so that the sealing ring ii 23 is tightly attached to the valve core 8, and the sealing effect of the sealing ring ii 23 on the ball valve is enhanced.
In particular, the electrode direction of the coil A, B, C, D and the magnetic pole direction of the bar-shaped ferromagnetic iron 3 can be adjusted.
When no fluid exists at the water outlet 17, the opening state of the ball valve can reach the hundred percent opening state shown in fig. 5, but when the flow rate of the liquid is gradually increased, the liquid at the outlet 17 is led to a drainage component, the liquid contacts with the sealing ring 20 to push the valve core 8 to rotate anticlockwise, the opening degree of the ball valve is reduced, the flow rate at the rear is reduced, so that the ball valve is balanced at a certain opening degree, and the rotating effect of the magnetic force on the valve core 8 is equal to the rotating effect of the rear fluid on the valve core 8; when the water pressure of the water outlet 17 is reduced, the driving effect of the magnetic force is larger than that of the fluid, and the valve core 8 rotates clockwise to increase the opening of the ball valve so as to increase the flow of the water outlet 17; when the water pressure of the water outlet 17 is increased, the driving effect of the magnetic force is smaller than that of the fluid, and the valve core 8 rotates anticlockwise to reduce the opening of the ball valve, so that the flow of the water outlet 17 is reduced, and the pressure reducing effect is achieved.
