# Control valve

## Abstract

Various embodiments include a control valve comprising: a valve body having a fluid inlet, a fluid outlet, and an inner cavity between them; a flow rate presetting assembly; and an indicator. The rate setting assembly includes: an adjusting rod having a first end projecting from the body and a second end extending into the cavity, and rotating around an axis; a control component disposed at a bottom side of the body and connected to the first end to rotate the adjusting rod; and an adjusting component disposed in the inner cavity connected to the adjusting rod, rotating between a first position and a second position under the action of the adjusting rod to set a maximum degree of opening of the control valve. The deviation of the indicating part relative to a reference position indicates a maximum flow rate corresponding to a position of the adjusting component.
