1. device that comprises equalizing valve or flow-limiting valve comprises:

  • Valve body/member is configured to have flow indicator or the scale of the setting between the minimum flow position of being included in and the maximum flow position, and each described setting has the printing flow with suitable measuring unit'"'"'s calibration with the every time increment of volume;

    AndKnob, it has position indicator and is configured in response to the power that is applied by the user, be moved to described flow indicator between described minimum flow position and the maximum flow position or any continuous position on the scale, wherein, relation between the described flow indicator of described valve body/member or the described position indicator of scale and described knob is at least in part based on the calibrated fluxes characteristic of described equalizing valve or flow-limiting valveThereby, by described knob being moved to the position of the hope between described minimum flow position and the maximum flow position, described user can arrange in single job and wish flow basically accurately, and need not to determine the accurate flow of the described hope of described equalizing valve or flow-limiting valve with reference to printing flow curve or other forms of balance operator.
