Inflatable noise reduction flexible joint and application thereof

Abstract

The invention belongs to the field of water conservancy projects, and particularly discloses an inflatable noise reduction flexible joint and application thereof. The inflatable flexible joint comprises a rubber main body, an inflation valve, an elastic air bag film and a fixing assembly; the rubber main body is of a hollow structure, and an inflation valve seat is arranged on the rubber main body and used for fixing the inflation valve; the elastic air bag film is of a tubular structure and is arranged in the rubber main body, a gap between the elastic air bag film and the rubber main body forms an inflation cavity, the inflation cavity is inflated through the inflation valve, and meanwhile, a circulation channel is formed in the elastic air bag film and used for fluid conveying; the fixing assembly is used for fixing and sealing the rubber main body and the elastic air bag film and is directly connected with an infusion pipeline during use. According to the flexible joint, the inflation cavity is formed in the flexible joint, through cooperation of the rubber main body, the inflation cavity and the elastic air bag film, the displacement compensation capacity is guaranteed, meanwhile, structure and fluid conduction noise is reduced, structure vibration is isolated, and the noise elimination performance of the flexible joint is further improved.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and more specifically relates to an inflatable noise-reducing flexible joint and its application. Background technique [0002] In the field of hydraulic engineering, multiple fluid delivery channels are usually connected to achieve long-distance transportation. In order to compensate the displacement between the fluid conveying pipelines and reduce structural vibration and pipeline radiation noise, it is generally necessary to use flexible joints in the pipelines. [0003] At present, common flexible joints include clamp type flexible joints and spherical rubber joints. The structure of the clamp type joint is simple, but the elastic deformation of the sealing ring is small, which can only compensate for small pipeline displacements, and the effect of shock absorption and noise reduction is not obvious. Although the spherical rubber joint can reduce pipeline vibration and reduce st...
