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. 1-2, the present invention provides a technical solution: the utility model provides a prevent ball valve of jam, including spheroid 1, first valve body 2, second valve body 3 and valve rod 4, second valve body 3 runs through there is connecting rod 7, connecting rod 7 both ends are fixed connection dwang 6 and first bevel gear 15 respectively, 3 inner walls of second valve body are fixed with two dead levers 13, two dead levers 13 are fixed connection sliding sleeve 14 and second bearing 17 respectively, fixedly connected with second bevel gear 16 in the second bearing 17, second bevel gear 16 can mesh with first bevel gear 15, second bevel gear 16 and second bearing 17 run through threaded rod 12, second bevel gear 16 inner wall is equipped with the screw thread with threaded rod 12 assorted, can make threaded rod 12 be reciprocating motion along the axial at its rotation in-process, threaded rod 12 one end fixed connection movable block 18, movable block 18 fixed connection blade 19.

Specifically, as shown in fig. 1, a handle 5 is fixed on the rotating rod 6, and the rotating rod 6 can be conveniently rotated by a person through the handle 5.
