Flow-limiting valve for filling

The invention relates to the technical field of oil and gas extraction, and discloses a flow-limiting valve for filling. In the well completion filling operation process, the flow-limiting valve is in an open state, a plurality of flow guide holes in a valve element part of the flow-limiting valve expand a filling channel, the displacement requirement of particle filling can be met, the filling operation time can be shortened, and the filling efficiency can be improved. Meanwhile, after filling operation is completed, crude oil can be mined out of a well through flow guide holes in the early mining stage, and the crude oil mining efficiency is improved. After the flow-limiting valve is closed, normal mining operation is not affected. In the later stage of oil well production, a pipe column can be put down to inject chemical agents into the stratum through the flow-limiting valve, after injection is completed, the flow-limiting valve is automatically closed under the action of fluid from outside to inside in t
