Sealing performance detection system

The invention relates to the technical field of optical fiber through device sealing device, and discloses a sealing performance detection system which is used for sealing performance detection of an optical fiber through device. The sealing performance detection system comprises a pressure gas generation device, a drying and filtering device, a valve component, a pressure detection device and a sealing performance detection device which are connected in turn in a sealing way through a pipeline. The pressure gas generation device is used for providing pressure gas. The drying and filtering device is used for drying the pressure gas outputted by the pressure gas generation device. The valve component is used for adjusting the pressure of the pressure gas inputted to the sealing performance detection device and used for unloading the internal pressure of the sealing performance detection device after completion of sealing performance detection. The pressure detection device is used for detecting the inlet pressure of the sealing performance detection device. According to the sealing performance detection system, the sealing performance of the optical fiber through device can be effectively detected, and the sealing performance detection system is high in targeted performance, simple in the overall structure, small in space occupation and convenient in system building and simple in detection method.
