Abstract
A control gas ball valve for high pressure gas cooking appliances provides a linear surface slot along its rotation direction. When turned by a control knob and enters a gas inlet, the said surface slot is able to channel gas input to a hole that connects said surface slot to the center of the valve ball. The gas in the center of the valve ball is directed away to a burner for cooking purposes. The said linear surface slot is able to provide constant flowrate slope for continuously variable power adjustment and a maximum power plateau. These are the most desirable features in residential cooking.
