Embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

As shown in Figure 1, the gas temp control valve that a kind of gas burning roastor is used, comprise valve body 1, valve gap 2, valve rod 3, pressure spring 4 and spool 5, on described valve body 1, there are intake interface 11 and spool chamber point-blank 12 and outlet chamber 13, described spool 5 comprises upper cavity 51 and lower chamber 52, and there is a draw-in groove 511 upper end of described upper cavity 51; There is a counterbore 31 lower end of described valve rod 3, the fixture block 32 having on the circumferential wall of lower end; In the upper end of described pressure spring 4 and embedding counterbore 31, lower end coordinates with the base plate of upper cavity 51, and the base plate of described upper cavity 51 is the dividing plate of upper and

lower cavity

51,52; On lower chamber 52 walls of described spool 5, be provided with gas port, gas port coordinates with intake interface 11; Described fixture block 32 coordinates with draw-in groove 511.During use, the interface 131 of giving vent to anger on outlet chamber 13 is communicated with burner.
