Problems solved by technology

[0003] However, the spool of the ball valve is a spool with a cavity inside, which will cause part of the fluid with high viscosity to partially adhere to the inner wall of the cavity after flowing through the internal cavity of the ball valve spool, resulting in a ball valve. jam
At this time, the cleaning operation of the ball valve is usually to open the valve body, take out the valve core and then clean it. The efficiency of the entire ball valve

Embodiment Construction

[0027] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] combine figure 1 and figure 2 As shown, the ball valve of this embodiment includes a valve body 1, four valve cores 2, a turntable 3 and a driving assembly. The valve body 1 is provided with an inlet 11 and an outlet 12 which are located on the same straight line and can communicate with each other. Each spool 2 is provided with a through hole 21, and the four spools 2 are distributed on the turntable 3 and the axis of rotation around the turntable 3 is evenly distributed along the circumferential direction, and can be rotated with the turntable 3 relative to the valve body 1. During the process, the inlet 11 and the outlet 12 are connected in sequence. The driving assembly is connected with the turntable 3 to drive the turntable 3 to rotate relative to the valve body 1 .

Abstract

The invention belongs to the technical field of pipeline valves and discloses a ball valve. The ball valve comprises a valve body, valve elements, a rotating disc and a driving assembly, an inlet and an outlet are formed in the valve body, the rotating disc is rotatably connected with the valve body and located between the inlet and the outlet, the valve elements are provided with through holes, the valve elements are distributed on the rotating disc and can communicate with the inlet and the outlet in sequence in the process that the rotating disc rotates relative to the valve body, and the driving assembly is connected with the rotating disc to drive the rotating disc to rotate relative to the valve body. According to the ball valve, the blocked valve elements can be rapidly replaced, and continuous and stable operation of the whole ball valve is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pipeline valves, in particular to a ball valve. Background technique [0002] Ball valves usually use a ball with a circular passage as the opening and closing element. Because of its advantages such as small fluid resistance, simple structure, compact and reliable, convenient operation, rapid opening and closing, and wide application range, it is widely used in petroleum, The conduction and cut-off of various devices such as chemical industry, electric power, steel, natural gas, coal chemical industry, polysilicon, etc., especially for valves in devices with a large number of solid particles and multi-phase complex media. [0003] However, the spool of the ball valve is a spool with a cavity inside, which will cause part of the fluid with high viscosity to partially adhere to the inner wall of the cavity after flowing through the internal cavity of the ball valve spool, resulting in a ball valve. clogge...
