Example Embodiment
[0024] In the following, the present invention will be described in detail and completely through specific embodiments in conjunction with the accompanying drawings.
[0025] Please refer to Figure 1-5 As shown, the present invention provides a spherical body sealing structure, including a spherical body and a first valve core 1, the surface of the first valve core 1 is provided with a valve port 11, the inner hole diameter of the valve port 11 is smaller than the diameter of the sphere, and the valve port 11 is provided with a valve port 11. There is a conical sealing surface 12, and the conical sealing surface 12 is provided with a circular arc sealing surface 13 that is consistent with the circular arc surface of the sphere. to form a sealing structure. When the sphere blocks the valve port 11, the sphere can abut on the arc sealing surface 13 to form a surface seal, the sealing structure is reliable, and compared with the way of directly disposing the arc sealing surface...
