Abstract:
    The automatic detection device for response time and leakage of solenoid valve includes detection circuit and detection fluid pipeline. The detection circuit controls the work valve, vacuum pump and tested fluid valve to alter the tested fluid pipeline; and includes liquid level sensor negative pressure sensor and positive pressure sensor. The detection fluid pipeline includes positive pressure gas source, negative pressure gas source, gas chamber and liquid storing container. The present invention makes it possible to detect the response time and the leakage of solenoid valve simple, accurately and reliably in the same device.
