[0023] The present invention is a normally closed pulse valve.

The following description refers to the above definitions.

[0024] There is high pressure in the A chamber, and the A chamber is connected to the B chamber through the first flow-limiting hole 18. The pressure in the B chamber exerts a downward force on the first diaphragm 14, so that the magnetic-sensitive piston 15 is in close contact with the port of the first throat pipe 17, thereby ensuring the disconnection between the A chamber and the C chamber; the B chamber is connected to the E chamber through the first pressure relief channel 24 and the second flow-limiting hole 29, and then the pressure in the E chamber exerts a downward force on the second diaphragm 26, so that the second diaphragm 26 is in close contact with the port of the second throat pipe 24, thereby ensuring the disconnection between the D chamber and the E chamber; the E chamber is connected to the inner cavity of the pressure relief seat 3 through the second pressure relief channel 32, and the moving iron core 41 is blocked on the port of the third throat pipe 33 through the sealing plug 42, so that the second pressure relief channel 32 and the second pressure relief hole 34 remain disconnected;

[0025] The junction box 5 receives an external signal to open the circuit of the magnetic coil 4. The magnetic coil 4 is energized to move the moving iron core 41 away from the third throat 33. At this time, the second pressure relief channel 32 is connected to the second pressure relief hole 24 to release the pressure in the E chamber; the magnetic coil 4 can drive the magnetic action piece 27 to move and drive the second diaphragm 26 away from the second throat 24. The B chamber is connected to the D chamber through the first pressure relief channel 22 to release the pressure in the B chamber. At this time, the magnetic coil 4 can drive the magnetic piston 15 away from the first throat 17, so that the A chamber and the C chamber are connected to output pulse air pressure.

[0026] The junction box 5 is provided with a data collector and a wireless communication module. The data collector is connected to a humidity sensor 51, a temperature sensor 53, an electrical signal sensor 54 and a plurality of pressure sensors 52 through lines. The data collector is integrated with a data storage unit, which is connected to the wireless communication module.

[0027] The data collector on the junction box 5 communicates data with the background through the wireless communication module. The background analyzes the data collected by each sensor to realize real-time monitoring of the operating status of the electromagnetic pulse valve, and realizes remote fault diagnosis and alarm functions.

[0028] The data analysis and fault identification logic rules of the present invention are as follows;

[0029] a. When the pressure at the air inlet 11 of the electromagnetic pulse valve is lower than the set pressure for a long time, the magnetic coil 4 heats up. The electric signal sensor 54 can detect that the magnetic coil 4 is powered on for a long time, and the temperature sensor 53 detects that the magnetic coil 4 is continuously at a high temperature. The pressure sensor 52 arranged at the air inlet 11 of the valve body 1 detects that the pressure at the air inlet 11 is continuously lower than the set pressure. The detected data is transmitted to the remote server by the wireless communication module through the data acquisition device and the data storage unit. After analysis and processing by the remote server, a fault diagnosis result that the moving iron core 41 has not been reset can be obtained.

[0030] b. When the electromagnetic pulse valve appears in the state that the magnetic coil 4 is not energized and the pressure at the air inlet 11 is continuously lower than the set pressure, the electric signal sensor 54 can detect that the magnetic coil 4 is not energized, and the pressure detected by the pressure sensor 52 arranged at the air inlet 11 of the valve body 1 is continuously lower than the set pressure and greater than the pressure detected by the pressure sensor 52 arranged in the first constant pressure chamber 21. The detected data is transmitted to the remote server via the data acquisition device and the data storage unit. After analysis and processing by the remote server, a fault diagnosis result can be obtained that the first diaphragm 14 does not close the air inlet 11 of the valve body 1 or the first diaphragm 14 is damaged.

[0031] c. When the electromagnetic pulse valve occurs when the magnetic coil 4 is powered on and then powered off, and the pressure at the air inlet 11 is continuously lower than the set pressure, the power-on and power-off states of the magnetic coil 4 can be detected by the electrical signal sensor 54. The pressure detected by the pressure sensor 52 arranged at the air inlet 11 of the valve body 1 is continuously lower than the set pressure and is higher than the pressure detected by the pressure sensor 52 arranged in the first constant pressure chamber 21. The pressure detected by the pressure sensor 52 arranged in the second constant pressure chamber 31 is the lowest. The detected data is transmitted to the remote server by the wireless communication module through the data acquisition device and the data storage unit. After analysis and processing by the remote server, a fault diagnosis result can be obtained that the moving iron core 41 does not close the second pressure relief hole 34 of the pressure relief seat 3 or the first flow limiting hole 18 on the first diaphragm 14 is blocked by debris.

[0032] d. When the electromagnetic pulse valve is energized by the magnetic coil 4, the pressure at the exhaust port 12 of the valve body 1 does not change. The electric signal sensor 54 can detect that the magnetic coil 4 is energized, the temperature sensor 53 detects that the temperature of the magnetic coil 4 has increased, the pressure detected by the pressure sensor 52 arranged at the air inlet 11 of the valve body 1 continues to be lower than the set pressure, and the pressure sensor 52 arranged at the exhaust port 12 of the valve body 1 detects that the pressure does not change. The detected data is transmitted to the remote server by the wireless communication module through the data acquisition device and the data storage unit. After analysis and processing by the remote server, a fault diagnosis result that the pressure at the air inlet 11 of the valve body 1 is lower than the set pressure can be obtained.

[0033] e. When the electromagnetic pulse valve is energized on the magnetic coil 4, the pressure at the exhaust port 12 of the valve body 1 does not change. The electric signal sensor 54 can detect that the magnetic coil 4 is energized, the temperature sensor 53 detects that the surface temperature of the magnetic coil 4 has no obvious change, and the pressure detected by the pressure sensor 52 arranged at the air inlet 11 of the valve body 1 does not change. The detected data is transmitted to the remote server by the wireless communication module through the data acquisition device and the data storage unit. After analysis and processing by the remote server, a fault diagnosis result can be obtained that the power supply voltage of the magnetic coil 4 does not match, the power supply time is too short, or the magnetic coil 4 is damaged.

[0034] f. When the electromagnetic pulse valve works in a cold environment, after the magnetic coil 4 is energized, the pressure at the air inlet 11 of the valve body 1 does not change. The electric signal sensor 54 can detect that the magnetic coil 4 has been energized, and the pressure detected by the pressure sensor 52 arranged at the air inlet 11 of the valve body 1 does not change. The humidity value detected by the humidity sensor arranged at the air inlet 11 of the valve body 1 is greater than 40%. The detected data is transmitted to the remote server by the wireless communication module through the data acquisition device and the data storage unit. After analysis and processing by the remote server, the fault diagnosis result of the freezing of the moving iron core 41, the first diaphragm 14 or the second diaphragm 26 can be obtained.

[0035] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
