The sealing performance of the ABS electromagnetic regulating valve 11 is tested and evaluated through the sound and light indications of the air intake pressure gauge 5 and the air outlet pressure gauge 6.

[0051] After the above test is completed, first open the pressure-maintaining control switch of the ABS electromagnetic regulating valve 11, turn on the pressure-maintaining function of the ABS electromagnetic regulating valve 11, then open the pressure-maintaining air valve 351 and the cut-off air valve 352 to discharge the air pressure at the inlet end of the ABS electromagnetic regulating valve 11, wait for the gas pressure value displayed by the pressure gauge 6 at the outlet end to stabilize, set the test time and pressure drop standard of the pressure gauge 6 at the outlet end, and perform a sealing test on the pressure-maintaining function of the ABS electromagnetic regulating valve 11.
