Flow guide sleeve and viscous fluid degassing device

The utility model relates to the technical field of vacuum degassing, and particularly discloses a flow guide sleeve and a viscous fluid degassing device.The flow guide sleeve is provided with a through hole, a flow blocking wall is arranged on the periphery of the through hole, a flow guide groove is formed in the periphery of the flow blocking wall, a flow guide hole is formed in the bottom of the flow guide groove, and the flow blocking wall is higher than the bottom of the flow guide groove; the inlet of the flow guide groove is used for being communicated with the feeding port of the viscous fluid degassing device, so that viscous fluid enters the flow guide groove through the feeding port of the viscous fluid degassing device and then flows to the umbrella skirt assembly through the flow guide groove and the flow guide hole, the viscous fluid is further prevented from being adhered to the power shaft, and the degassing effect of the viscous fluid is improved. 本实用新型涉及真空除气技术领域，具体公开了一种导流套及粘性流体脱气装置，该导流套通过设置
