For example, when the valve core 2 and the valve rod 6 are radially connected in a matching manner, the matching end of the valve rod 6 may be an annular wall, and the valve core 2 may be provided with a boss; in order to improve the sealing performance of the external air supply pipeline joint 3 and the valve hole of the valve body 1, a plurality of first sealing rings can be arranged at different axial positions of the external air supply pipeline joint 3; the shapes of the first sealing ring, the second sealing ring and the third sealing ring can be other than O-shaped rings; the number of the gas transmission channels communicated with the gas outlet output channel 1-1 on the valve body 1 is determined according to the number of gas transmission pipelines required by the rotary gas stove, and can be multiple; etc. which can be made by those skilled in the art based on their basic skills in understanding the concept of the present invention and are not to be construed as exemplary only.
Finally, it is to be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not intended to be limiting. It will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention, and these changes and modifications are to be considered as within the scope of the invention.
