An inner threaded sleeve 2212 is further formed upwards at the edge of the opening of the circumferential groove 228, and the inner threaded sleeve 2212 is sleeved and screwed outside the lower end of the valve sleeve 21.

A limiting ring 212 is also formed outwards on the outer wall of the valve sleeve 21, and the top of the limiting ring 212 is tightly propped against the bottom outer wall of the electromagnetic coil 1.

The upper end of the valve sleeve 21 is further provided with a stud 213 upwards, the stud 213 is further sleeved with a nut 26 in a screwed connection mode, a protection gasket 27 is further arranged between the nut 26 and the top outer wall of the electromagnetic coil 1, the protection gasket 27 is sleeved on the stud 213, and the nut 26 compresses the protection gasket 27 on the top outer wall of the electromagnetic coil 1 to fix the valve sleeve 21 in the electromagnetic coil 1.

Working principle: the power line is connected with the electromagnetic coil 1 through the junction box 3, then the liquid inlet pipe and the liquid outlet pipe are respectively inserted into the first counter bore 221 and the second counter bore 222, and then the third counter bore 223 is closed or is connected with the first counter bore 221 of the other two-position three-way electromagnetic valve by using a connecting pipe so as to realize parallel connection.

When the electromagnetic coil 1 is electrified, magnetic attraction force is generated, and the iron core 23 is lifted upwards by the magnetic attraction force and compresses the spring 24, so that the sealing block 24 is lifted and separated from the top of the boss 229 to open a passage of liquid medium; at this time, when the third counter bore 223 is closed, the liquid medium sequentially enters the annular groove 228 through the fourth counter bore 224 and the liquid inlet 225, then enters the fifth counter bore 226 through the first liquid outlet 227, and finally is discharged outwards through the second counter bore 222 and a corresponding liquid outlet pipe; when the third counterbore 223 is connected with the first counterbore 221 of the other two-position three-way electromagnetic valve through the connecting pipe, a part of the liquid medium in the first counterbore 221 enters the sixth counterbore 2210 through the second liquid outlet hole 2211, and is then output to the first counterbore 221 of the other two-position three-way electromagnetic valve through the third counterbore 223 and the connecting pipe.

When the electromagnetic coil 1 is powered off, the magnetic attraction force disappears, the iron core 23 moves downwards under the action of the rebound force of the spring 24 to enable the sealing block 24 to be pressed on the top of the boss 229 again, and further the first liquid outlet hole 227 is closed, so that the flow of liquid medium is cut off, the two-position three-way electromagnetic valves are always communicated by virtue of the connecting pipe, and even if the liquid medium in the last two-position three-way electromagnetic valve stops outputting, the input of the liquid medium of the next two-position three-way electromagnetic valve is not influenced.
