Embodiment Construction
[0013] figure 1 It is a structural schematic diagram of a new type of flow regulating gate valve of the present invention, mainly including a fine-tuning handwheel (1), a fine-tuning valve stem (2), a stem nut (3), a coarse-tuning handwheel (4), and a coarse-tuning valve stem ( 5), packing pressure plate (6), packing (7), valve cover (8), gate (9), valve body (10) and other structures.
[0014] Coarsely adjust the flow rate or when the flow rate is required to be fully open or fully closed, turn the coarse adjustment handwheel (4) to move the coarse adjustment valve stem (5) up and down, which can realize rapid flow changes and save time; when the flow rate is finely adjusted, turn the fine adjustment handwheel (1), hold the coarse adjustment handwheel (4) at the same time, and make the fine adjustment valve stem (2) move up and down slightly, so as to realize the fine adjustment of the flow rate and save time.
