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 in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a low corrosion ball valve foundry goods that wear and tear, including valve body 1, take over 2, the caulking groove 3, retaining ring 4, cooperation mouth 6, bottom 7, inner block 8, cushion 9 and

flange dish

11, 1 both ends connection of valve body is fixed with takes over 2, and take over 2 end fixing has flange dish 11, caulking groove 3 has been seted up to the port position that 1 inside of valve body lies in and takes over 2 connections, and retaining ring 4 is installed through 3 joints of caulking groove to 1 inside of valve body, cooperation mouth 6 has been seted up to 1 bottom of valve body, 6 port positions of cooperation mouth are fixed with bottom 7 through the screw cooperation, bottom 7 surface is located 6 inboards of cooperation mouth and rotates through the bearing and installs
