| 摘要 |
The present invention relates to an uniaxial disk pressurized butterfly valve installed on a pipeline in which a fluid flows for controlling the flow of the fluid, and more specifically, to an uniaxial disk pressurized butterfly valve having a structure in which a disk installed at rotary shaft inside a main body for controlling the fluid is separated from the rotary shaft when rotating at a certain angle, and is capable of moving toward a main body sheet separately from the rotary shaft. The structure of the valve according to the present invention enables the rotation of the disk and the movement of the disk by only rotating the single rotary shaft, thereby minimizing the abrasion of a disk sheet and the main body sheet, and improving a sealing force due to the pressurization of the movement of the disk. |
