Abstract
PURPOSE: To secure desired flow ratio in wide flow range by combining equalizing valve and proportional valve.
CONSTITUTION: Whenever burner 11 and the like needs flow in wide range, operation valve 4 for small flow period is closed together with the opening air side small flow control valve 3 and gas side small flow control valve 8 to fix at full opening under the specified opening ratio. Flow is controlled with large flow control valve 2 without relieving air from relief pipe 5. In this case, proportional control by use of equalizing valve system can be applied with large flow control valve 2 and equalizing valve 7. For example, when flow controllable range is rated 5:1, this enables to control 100% to 20% of large flow range at a certain ratio. For controlling flow of small flow range, large flow control valve 2 is fixed at the minimum opening, a part of air being relieved from the relief pipe 5 by actuating small flow period actuating valve 4, and controlling flow by interlocking air side small flow control valve 3 with gas side small flow control valve 8.
