The working principle of the electromagnetic reversing valve is as follows: in normal operation, the air flowing in from the P air inlet 31 is closed by the first opening valve 26A and the second opening valve 26P, and cannot flow to the a air outlet 41, and at this time, the a air outlet 41 communicates with the E air outlet 21, and the pilot supply air passage is closed by the first pilot valve 22A and the second pilot valve 22P. When the electromagnets are excited, the first electromagnet 21A and the second electromagnet 21P are energized, the first pilot valve 22A and the second pilot valve 22P are opened, the air passage pressurizing force is applied to the upper portions of the first piston 23A and the second piston 23P, the first piston 23A and the second piston 23P are depressed, the first opening valve 26A and the second opening valve 26P are opened, air flows from the P air inlet 31 to the a air outlet 41, and simultaneously, the first gasket 24A and the second gasket 24P close the passage because of the depressed first piston 23A and second piston 23P, and the E air outlet 21 is closed. When the electromagnet is demagnetized, the current to the first electromagnet 21A and the second electromagnet 21P is cut off, the first pilot valve 22A and the second pilot valve 22P are closed, air on the upper portions of the first piston 23A and the second piston 23P is discharged to the atmosphere, the first piston 23A and the second piston 23P and the first gasket 24A and the second gasket 24P return to the original positions due to the air pressure discharged from the a air outlet 41 to the E air outlet 21, the passage is opened, and the air of the a air outlet 41 is discharged to the E air outlet 21. Meanwhile, the first and second valve spools 25A and 25P, the first and second open valves 26A and 26P are reset due to the spring force of the first and second springs 27A and 27P and the force of the air of the P intake port 31, and the air of the P intake port 31 is closed due to the first and second open valves 26A and 26P. In case that the electromagnet on one side burns out, for example, the second electromagnet 21P burns out, the second pilot valve 22P is not opened, and in the state where the first electromagnet 21A and the second electromagnet 21P are not energized, the first pilot valve 22A and the second pilot valve 22P are not opened, and the air of the P air inlet 31 does not flow to the a air outlet 41 due to the first opening valve 26A and the second opening valve 26P being closed. The first electromagnet 21A and the second electromagnet 21P are energized, only the first pilot valve 22A is opened, and air flows through the main valve a to the a air outlet 41. Since the passage of the main valve P is opened, the passage of the main valve a is considerably more damped than the passage of the main valve P, most of the air is discharged from the E-gas outlet 21 to the atmosphere without flowing to the a-gas outlet 41, and the output of the a-gas outlet 41 is controlled to be less than 10% of the P-gas inlet 31, so that the air which is substantially led to the a-gas outlet 41 is in a non-flowing state, and at this time, the air which is continuously supplied through the passage of the main valve a is continuously discharged to the E-gas outlet 21 with the accompanying sound, so that a failure is easily found, and the double protection is provided, and the safety factor is high.
The foregoing is a preferred embodiment of the present utility model, but the present utility model should not be limited to the embodiment and the disclosure of the drawings, so that the equivalents and modifications can be made without departing from the spirit of the disclosure.
