[0026] In the embodiment, the adjusting sleeve 50 is arranged on the outer periphery of the valve body 10 and is connected with the end of the adjusting rod 32, and rotation of the adjusting sleeve 50 can be used for adjusting the rotation angle of the valve piece 20, so as to make the first through hole 42 and the second through hole 21 block each other to cut off the above-mentioned channel 11, or make the first through hole 42 and the second through hole 21 overlap each other to open the above-mentioned channel 11. The adjusting sleeve 50 is rotationally and sealingly connected with the valve body 10, which can avoid direct contact between the adjusting rod 32 and the sealing member, avoid abrasion of the sealing member by the adjusting rod 32, and improve the service life of the burner nozzle control valve. In addition, the arrangement of the adjusting sleeve 50 also makes the overall structure of the burner nozzle control valve more regular, and the size of the valve opening and closing cannot be changed by accidental touch of the handle.

[0027] In some embodiments, the burner nozzle control valve further comprises a plurality of first sealing rings (not shown in the figure) arranged on the valve body 10 and arranged along the axial direction, and the first sealing rings are arranged on both sides of the arc-shaped hole 12 and are used for rotationally sealing the valve body 10 and the adjusting sleeve 50.

Specifically, a mounting groove 13 can be arranged on the valve body 10, and the first sealing ring is clamped in the mounting groove 13, and the outer side of the first sealing ring is in abutment with the inner wall of the adjusting sleeve 50. Arrangement of a plurality of first sealing rings can achieve the effect of double-layer sealing and improve the sealing effect between the adjusting sleeve 50 and the valve body 10.

[0028] In addition, a protrusion 14 can be arranged on the outer periphery of the valve body 10, and the protrusion 14 is used for limiting the adjusting sleeve 50. Of course, a nut can also be arranged on the end of the valve body 10 away from the cover, the nut is spaced apart from the above-mentioned protrusion 14, the adjusting sleeve 50 is arranged between the protrusion 14 and the nut, and the nut can also limit the side of the adjusting sleeve 50 away from the protrusion 14.

[0029] In some embodiments, two arc-shaped holes 12 are symmetrically arranged on the valve body 10, and the adjusting rods 32 are arranged along the radial direction and correspondingly arranged with the two arc-shaped holes 12. The end of the adjusting rod 32 extends to the outside of the valve body 10, and the inner wall of the adjusting sleeve 50 is further provided with a butt joint hole or a butt joint groove 51 for butt joint with the adjusting rod 32. In this embodiment, a ring-shaped protrusion 52 can be arranged on the middle section of the inner wall of the adjusting sleeve 50, and the butt joint groove 51 extends along the axial direction and is arranged on the ring-shaped protrusion 52.

The adjusting rod 32 can pass through the butt joint hole, the limiting hole and the third through hole in sequence, and then enter the limiting hole and the butt joint hole on the other side. In this way, the connection between the adjusting rod 32 and the adjusting sleeve 50 is realized. Of course, the outer port of the butt joint hole still needs to be plugged in the end to avoid gas leakage. By arranging the butt joint groove 51 and the butt joint hole, the installation of the adjusting sleeve 50 and the adjusting rod 32 is facilitated.

[0031] In some embodiments, the baffle plate 41 is further provided with a first mounting hole 43 in the center, and the first through hole 42 is arranged on one side of the first mounting hole 43; the valve disc 20 is further provided with a second mounting hole 22 in the center; and the burner nozzle control valve further comprises a screw penetrating the first mounting hole 43 and connected with the second mounting hole 22. The head of the screw is arranged on the outer side of the baffle plate 41, the screw can rotate in the first mounting hole 43, and the other end of the screw is fixed in the second mounting hole 22.
