The flow control column 702 slides along the left guide surface 2023 and the right guide surface 2024 on the inner wall of the upper sleeve 2021. The sliding direction of the flow control column is limited so that it can only move along the axial direction of the sleeve 202 but cannot rotate circumferentially, thereby ensuring the accuracy of the flow control column in regulating the flow.
