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.
Claims3
A ball valve for controlling gas flow for a cooking appliance comprising:
- a center hole drilled through the center to direct gas out to a burner and an ignition path,
- a cut slot on one end of said drilled hole to mate with a turning shaft such that the ball valve can be rotated along a rotation direction,
- a surface slot on the ball along said rotation direction,
- a path hole in the path of the said surface slot. The said path hole is drilled between said surface slot to said center hole,
- whereby said path hole collects gas coming from said surface slot to said center hole to an appliance burner such that said burner flame and power is continuously adjustable.
