The invention relates to a metering device and a spandex dry spinning part. The metering device comprises at least one metering unit and at least one connector converting part. Each metering unit comprises at least one inlet and a plurality of outlets. The multiple outlets of each metering unit are arranged in a nonlinear mode. Each connector converting part comprises a plurality of inlets and a plurality of outlets, wherein the inlets and the outlets are communicated correspondingly through a plurality of flow guide conversion channels. At least some parts of each connector converting part and at least some outlets of each metering unit are correspondingly arranged in a nonlinear mode and communicated. The multiple outlets of each connector converting part are arranged in a linear mode. According to the metering device and the spandex dry spinning part, the nonlinear arrangement mode of the outlets of the metering units can be converted into a linear arrangement mode, the outlets of the metering device can be matched and directly connected with inlets of spinning assemblies without metal hoses, the space utilization rate is increased, the production efficiency is improved, and cost is reduced.
