Abstract

The invention relates to a ball valve sealing structure, which comprises a valve body, a valve core, a valve core, a valve core, a first valve core, a second valve core and a second valve core, wherein the valve body is internally provided with a first channel and a cavity communicated with the first channel; the ball body is rotatably installed in the cavity, a second channel is formed in the ball body, and the second channel is used for being communicated with the first channel when the ball body rotates by a preset angle; the first valve seat is mounted in the cavity, and the first valve seat is arranged on one side of the ball body; the second valve seat is arranged on the side, away from the first valve seat, of the ball body, the second valve seat is installed in the cavity in a floating mode through a sealing pair, and the sealing pair is arranged between the second valve seat and the valve body in a clamped mode. The valve seat on the outer side of the ball body and the valve body are installed in a floating mode through the sealing pair, the ball valve can be protected and sealed, coarse particles in fluid are prevented from filling a sealing cavity, the service life of the ball valve is prolonged, the equipment operation cost is reduced, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical fields of coal chemical industry and polysilicon, in particular to a ball valve sealing structure. Background technique [0002] At present, the main function of the ball valve in the pipeline is to cut off, distribute and change the flow direction of the fluid. It only needs to be rotated 90 degrees and a small rotational torque can be closed tightly. [0003] In the related technology, the ball valve installed in the black water system of polysilicon and coal chemical industry, because the fluid contains a large amount of solid particles, during the use of the ball valve, coarse particles often fill the sealing cavity, and the ball switch is jammed and inflexible, resulting in a short service life of the ball valve , frequent shutdowns for maintenance, not only high equipment operating costs, but also seriously affect production efficiency. Contents of the invention [0004] The embodiment of the present inve...
