Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings and implement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is used only for explaining
This utility model, is not used to limit this utility model.
As Figure 1-5, a kind of ball valve, including valve body 1, handle 2, valve rod 3, pointer 4, liner 9, valve ball 7, leakproof
Glass ring 8, valve seat 6, wherein graduated disc 10, valve seat 6 are arranged on 1 inner chamber of valve body, and liner 9 is arranged in valve seat 6, and valve ball 7 is located at
It is in elliposoidal in liner 9, is macromolecular material, 7 surface of valve ball is provided with lubricating layer, be provided between liner 9 and valve ball 7
Leakproof glass ring 8, leaves aperture 91 on liner 9, and leakproof glass ring 8 and 9 section face of liner are provided with little inserted link 82, liner
9 aperture 91 is fit like a glove with the little inserted link 82 of leakproof glass ring 8, is formed seamless contact by binding agent, be increased leakproof
Compactness between glass ring 8 and liner 9, is prevented from leakproof glass ring 8 and causes a departure from 7 rotation process of valve ball and cause
Clogging；The surface of wherein valve ball 7 is provided with annular groove 71, is provided with and ring in leakproof glass ring 8 and 7 contact surface of ball valve
The fin 81 that connected in star 71 matches, is guaranteed that by way of concavo-convex combination valve ball 7 is directly firm with leakproof glass ring 8 and is connect
Touch；Plug together with 3 bottom of valve rod on 7 top of ball valve and be connected, wherein handle 2 and graduated disc 10 sequentially pass through valve rod 3 from top to bottom and set
