As shown in fig. 4, three electromagnet units are arranged in a dashed line frame, the electromagnet unit a and the electromagnet unit C control the movement of the left push rod together, and the electromagnet unit B controls the movement of the right push rod, so that one valve controls the opening and closing of two pipelines. The armature is stressed mainly by electromagnetic force and spring force, and in a static state, the spring force and the electromagnetic force are in a balanced state, and the spring force can be controlled by changing the electromagnetic force, so that the compression amount of the spring is controlled to realize armature displacement control. The main parts of the electromagnetic mechanism are an armature and a pole shoe, and the pole shoe adopts a basin-shaped structure, so that the electromagnet can be ensured to generate stable electromagnetic force, and the opening of a valve port can be controlled by controlling the electromagnetic force according to input current. Fig. 5 shows the movement process of the valve port device of the solenoid valve, where d is the relative distance between the sleeve port and the central line of the through hole of the push rod, and it can be seen from the figure that when the device is opened, d gradually decreases, and when d is 0, the valve port is fully opened. As shown in figure 6, the integral device and the left and right pipelines are schematically shown when the electromagnetic valve is opened, a shaft sleeve is added at the valve core, the pipeline in the figure shows the flowing direction of liquid, and the internal action of the electromagnetic valve can be visually seen. Fig. 7 shows a trend chart of the magnetic circuit of the solenoid valve, which is divided into three electromagnet units and has 6 closed magnetic circuits. The winding mode of the coils in the three coils is anticlockwise winding when viewed from left to right. When the three coils are electrified simultaneously, the direction of the electrified current is perpendicular to the paper surface and faces inwards, the direction of the magnetic force lines generated by the electrified coils is obtained through right-hand screw rule, the solid lines in the figure represent the magnetic force lines of the upper and lower electromagnetic mechanisms, and the dotted lines represent the magnetic force lines of the middle electromagnetic mechanism, as shown by the solid lines and the dotted lines in the figure.
The invention has the advantages of miniaturization, modularization, economy, practicality, stable and reliable operation and the like, and the adopted proportion electromagnet part is not only suitable for the pipeline switch provided by the invention, but also suitable for the field of electromagnetic valves, such as an electromagnetic overflow valve, a pressure reducing valve and the like.
The electromagnetic valve is divided into two channels, and the opening and closing of the pipeline are realized by controlling the three coils. In the initial state, the springs in the three electromagnetic mechanisms are all in a compressed state, and the push rod is pushed outwards through the spring force, so that the pipeline is in a closed state. When the first coil No. 11 and the third coil No. 29 are electrified, the first armature No. 16 and the third armature No. 28 move rightwards, the left push rod 11 is driven to move rightwards, and a left pipeline is opened. When the second intermediate coil 18 is electrified, the second intermediate armature 19 moves leftwards to drive the right push rod 20 to move leftwards, and the right pipeline is opened. In the occasion of needing high frequency on-off, the permanent magnet 25 can replace a spring, and the purpose can be achieved only by adjusting current. After the first coil 11 and the third coil 29 are powered off, the upper armature and the lower armature and the push rod move leftwards under the action of the spring force, so that the left pipeline is closed. After the second intermediate coil 18 is powered off, the second intermediate armature 19 and the right push rod 20 also move rightwards under the action of the spring force, so that a right pipeline is closed. After all coils are powered off, the electromagnetic valve can close the pipeline through spring force, and low power consumption self-maintenance is achieved. The switch electromagnetic valve device has compact structure and flexible control, is internally provided with an integrated circuit device, can realize multi-stage expansion on axial and radial theories, and realizes multi-channel control. The on-off control of the flow passage can be controlled by setting a program on a circuit board 5 arranged in the electromagnetic valve.
