Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
First embodiment
Referring to Fig. 1-Fig. 5, this gas burning roastor stopcock comprises valve body 10, valve seat 2, spool 8, push rod 4, seal ring 7, rotating shaft 3, locking nut 13, Flow-rate adjustment screw 9 and flame-out protection device 12; Its valve body and valve seat adopt the aluminium die cast, and both connect by the first machine silk; Valve body comprises the main regulation path 10 .1 that is positioned at the middle part, and the main regulation passage left and right sides is provided with left gas outlet 10.3 and right gas outlet 10.4, and main regulation passage downside is provided with fuel gas inlet and flame-out protection device; Valve core rotation is arranged in the main regulation passage of valve body.
Its working principle is: stopcock is when holding state, depress rotating shaft and be rotated counterclockwise 90 degree, combustion gas enters one of them combustion chambers burn of baking box by stopcock, thermocouple produces thermoelectrical potential, the solenoid valve adhesive, at this moment, blast tube is opened, and continue to provide combustion gas to baking box, keep the baking box proper functioning.Too high as temperature in the baking box, in the time of need regulating temperature, another mistake hour hands rotating shaft until 165 degree, by regulating gas flow, thereby reaches the purpose of step-less adjustment the temperature inside the box.
