It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0024] Reference Figure 1 and Figure 2 The test device for testing the flow rate of a solenoid valve shown includes a square base 100, and a first threaded port and a second threaded port are provided on the side wall of the base 100.

[0025] The first test connector 110 is located inside the first threaded opening of the base 100;

[0026] The second test connector 120 is disposed in the second threaded opening of the base 100;

[0027] The solenoid valve assembly 130 is located near the second threaded port and is connected to the base 100.

[0028] In some specific embodiments, including:

[0029] The ends of the first and second connectors away from the base 100 are provided with threads;

[0030] The thread of the first connector is used to connect to the air outlet pipe;

[0031] The thread of the second connector is used to connect the air intake pipe.

[0032] In some specific embodiments, the solenoid valve assembly 130 is fixed to the base 100 by bolts.

[0033] In some specific embodiments, the base 100 is sealed with a high-pressure resistant fluororubber sealing ring.

[0034] The rubber sealing rings seal the first threaded port, the second threaded port, and the connection between the solenoid valve assembly 130 and the base 100.
