Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
With reference to the attached drawings 1-4, the large-flow rotatable cylindrical valve comprises a valve seat 1 and a valve cover 2, wherein the valve cover 2 is covered on the valve seat 1, and the large-flow rotatable cylindrical valve further comprises a rotatable valve column 3 positioned in the valve seat 1; the valve seat 1 is sequentially provided with a liquid inlet 11, a first liquid outlet 12 and a second liquid outlet 13, an included angle between the liquid inlet 11 and the first liquid outlet 12 is 180 degrees, and the second liquid outlet 13 is positioned in the middle of the liquid inlet 11 and the first liquid outlet 12; the valve column 3 is provided with three through holes 31 which are in one-to-one correspondence with the liquid inlet 11, the first liquid outlet 12 and the second liquid outlet 13 and have the same inner diameter, and the through holes are used for realizing the passing of liquid to be conveyed.
When the device is used specifically, the liquid inlet 11, the liquid outlet I12 and the liquid outlet II 13 are connected to a joint of pipelines or other equipment needing liquid separation, then a medium of a pipeline to be subjected to liquid separation enters the valve column 3 from the liquid inlet 11, and then when the two outlets need to be separated simultaneously, the valve column 3 is rotated, so that the through holes 31 in the valve column 3 are communicated with the liquid inlet 11, the liquid outlet I12 and the liquid outlet II 13 one by one; then, when an outlet is required to be shunted, the valve column 3 is rotated, so that two of the through holes 31 are respectively communicated with the liquid inlet 11, the first liquid outlet 12 or the second liquid outlet 13, and the purpose of outputting one outlet is achieved.
