Fecha de publicación: 15/07/2022 Fuente: Wipo "olive oil" The utility model discloses a horizontal air pre-heater pipe leakage detection device which comprises a pipeline and a detection mechanism, the detection mechanism is arranged on the side face of the pipeline, and the top of the detection mechanism is provided with a clamping structure connected with the pipeline. And the sliding pad is arranged at the joint of the detection mechanism and the pipeline, and a connecting assembly is arranged at the bottom of the sliding pad. According to the horizontal air pre-heater pipe leakage detection device, novel structural design is adopted, a clamping structure is designed, so that a pipeline can be stably clamped and fixed, the situation that a detection mechanism makes contact with fixed clamping of the pipeline when moving is avoided, and meanwhile, an extrusion structure is designed, so that when leakage detection needs to be conducted, the pipeline is not prone to being damaged. Oil in the oil storage bag can make contact with the side face of the pipeline through the oil outlet formed in the connecting assembly, then cold air is introduced, checking is conducted according to the characteristic that olive oil makes contact with the cold air and is solidified, the usability of the device is enhanced, and meanwhile leakage checking is more accurate.
