An air circuit control board for a pantograph test bench includes:

[0027] A valve plate 1, on one side of the surface of the valve plate 1, a one-way valve 4 is installed, and on the surface of the valve plate 1 and on one side of the one-way valve 4, a plurality of different solenoid valves 3 are installed. On the surface of the valve plate 1 and on one side of the solenoid valves 3, a filter pressure regulator 5 is installed. On the surface of the valve plate 1 and on one side of the filter pressure regulator 5, an electro-pneumatic proportional valve 6 is installed;

[0028] A plurality of quick connectors 7, and a plurality of the quick connectors 7 are all installed on the side of the valve plate 1.

[0029] The filter pressure regulator 5 is used to filter and manually adjust the air source pressure.

[0030] The electro-pneumatic proportional valve 6 is used to control the pressure continuously and proportionally according to the input electrical signal continuous data and proportional data.

[0031] Mounting brackets 8 are installed on both the left and right sides of the valve plate 1.

[0032] Please refer to Figure 4 to know that the filter pressure regulator 5, electro-pneumatic proportional valve 6, one-way valve 4, solenoid valve 3, and quick connector 7 are mainly installed on the control board. The pressure increasing valve and the air storage cylinder are installed separately in other positions and are not on the valve plate.

[0033] The external air source is connected to the air inlet of the valve plate 1 and is overall controlled by a two-way three-way solenoid valve. When the solenoid valve 3 is energized and conducts, the filter pressure regulator 5 is used to filter and manually adjust the air source pressure; the electro-pneumatic proportional valve 6 controls the pressure continuously and proportionally according to the input electrical signal. The output of the electro-pneumatic proportional valve 6 is divided into two paths. One path outputs normal air pressure, which is stored in the air storage cylinder for conventional tests. The other path outputs and installs a pressure increasing valve, which can increase the air source pressure to 1 Mpa, suitable for product tests that require high air pressure input.

[0034] After the two-way air pressure output, it is stored in the external first air reservoir through the quick interface 7. The output end of the air reservoir is then connected to the control board and divided into two paths. One path is used to connect to the input end of the test piece, and the output end of the test piece is connected to the second air reservoir. The other path is directly output to the air reservoir under the control of the solenoid valve. A pressure sensor is installed on the air reservoir to detect the actual output test pressure.
