The invention discloses a flow guiding device component, which is arranged inside gas disposal devices such as a filter, a pressure adjusting filter, and the like, and consists of a flow guiding device, and a filter core and an umbrella-shaped seat which are arranged below the flow guiding device; the upper part of the flow guiding device is a vane seat; the flow guiding vane is arranged at the edge of the external side of the vane seat; the center of the vane seat is provided with a connecting part; the middle part of the flow guiding part is provided with a centering chamber; the lower partof the flow guiding device is connected with the umbrella-shaped seat; the flow guiding device, the filter core and the umbrella-shaped seat form a whole structure after being connected with each other. The flow guiding device component effectively solves the problem of the prior art that the flow guiding devices on the filter and the pressure adjusting filter can not be commonly used; in the invention, the flow guiding device is fixed on the filter or the pressure adjusting filter; when the umbrella-shaped seat is removed for cleaning and maintenance, the flow guiding device does not fall off, the assembly/disassembly process is simplified, the assembly precision of the pressure adjusting filter is not affected, and daily maintenance operation is greatly simplified.
