Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a hard sealing ball valve comprises a valve body 1, a gland 2 and a handle 4, wherein the valve body 1 comprises a valve body outer shell 5, a silica gel layer 6 and a valve body inner shell 7, the silica gel layer 6 is filled between the valve body outer shell 5 and the valve body inner shell 7, a loop bar 3 is arranged at the top of the valve body 1 and the bottom of the gland 2, a valve rod 15 is arranged at the inner side of the loop bar 3, and the bottom end of the valve rod 15 is fixedly connected with a ball body 8, the upper end and the lower end of the ball body 8 are sleeved with a protective sleeve column 10, and inlay between protection sleeve post 10 and the spheroid 8 junction and be equipped with protection cushion 9, protection cushion 9 mainly plays and prevents spheroid 8 and protection sleeve post 10 wearing and tearing each other, installs sealed plug 11 between spheroid 8's both sides and the valve body inner shell 7, and the middle part of valve body inner shell 7 and spheroid 8 all runs through the intercommunication and has circulation hole 13, and installation panel 12 is installed to the equal symmetry in both sides of circulation hole 13, and the outer end of protection sleeve post 10 inlays the inboard of locating silica gel layer 6.
