Description

Lining tee bend does not have ball valve that is detained

Technical Field

The utility model relates to a ball valve technical field especially relates to a inside lining tee bend does not have delay ball valve.

Background

The three-way ball valve has a T shape and an L shape. The T shape can make three orthogonal pipelines mutually communicated and cut off a third channel, thereby playing the roles of shunting and converging. The L three-way ball valve type can only connect two mutually orthogonal pipelines, can not simultaneously keep the mutual communication of the third pipeline, and only plays a role in distribution. Ball valves are used in pipelines primarily to shut off, distribute and change the direction of flow of media. Ball valves are a new type of valve that is widely used.

The condition of weeping can appear during the liquid intercommunication in the ball valve, can influence the normal use of ball valve, and remaining liquid stays for a long time inside can lead to the fact the corruption to inside mechanism of ball valve, consequently needs to improve.

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. 1-4, the present invention provides a technical solution: the utility model provides a drawing manufacturing process inside lining tee bend does not have delay ball valve, includes valve body 1, still includes:

the lower valve body 2, the upper valve body 1 and the lower valve body 2 are fixed through the hexagon socket head cap screw 3;

the lining valve seat 4 is internally provided with a positioning seat 11;

the ball core 5 is provided with a through hole 7;

the four-corner groove 6 is clamped with the end part of the handle 8;

a limiting piece is arranged on the inner wall of the channel 9;

the connection port 20 and the channel 9 communicate with the connection port 20.

Specifically, as shown in fig. 2, the locating part includes fixed block 12, set up recess 13 in the fixed block 12, fixedly connected with gag lever post 14 in the recess 13, the cover is equipped with slider 15 on the gag lever post 14, it has the one end of dwang 16 to articulate on slider 15's the lateral wall, the other end of dwang 16 articulates there is stopper 17, the both ends of stopper 17 slide in spout 18, the inner wall of spout 18 is smooth and be equipped with the wearing layer, the welding has spring 19 between fixed block 12 and the stopper 17.

Specifically, as shown in fig. 2 and 3, a gasket 10 slidably connected with the ball core 5 is arranged in the lining valve seat 4, and the gasket 10 protects the ball core 5 and prevents the ball core 5 from being worn during rotation.

Specifically, as shown in fig. 2, the side wall of the limiting block 17 is provided with an elastic rubber ring, so that an internal sealing effect on the channel 9 can be achieved, and liquid is prevented from flowing into the inside when the ball valve is not used.

The working principle is as follows: during the use, the handle 8 is rotated, make ball valve internal passage 9 be linked together, liquid gives stopper 17 pressure through passageway 9, stopper 17 is consequently close to fixed block 12 gradually, spring 19 is compressed this moment, dwang 16 rotates, slider 15 is rebound under the restriction of gag lever post 14, consequently, stopper 17 that is close to ball core 5 keeps away from ball core 5 gradually, passageway 9 and connector 20 intercommunication, liquid can flow away through the circulation mouth 7 of seting up on the ball core 5, liquid source head when flowing is closed, hydraulic pressure descends, stopper 17 seals connector 20 under spring 19's effect, prevent that liquid from remaining inside the ball valve, thereby the leakage phenomenon appears.
