Sliding disk valve

The present invention is a sliding disc which can be in the, more particularly, disc valve made to open and close a sliding form on the disk valve, improve the use lifetime of the disk to improve the uneven wear of the disk that is in contact with the holes of a conventional disc to even wear It relates to a valve. Sliding disk valve plate (10) one end of the passage hole 11 formed in the tube is provided with a sliding disc valve which by opening and closing the passage holes 11 in the slide control and out of a fluid according to the present invention ( 100), and a passage hole 11 to, the sprocket is provided with disk 20 to open and close of said plate (10) including; The pressing portion for pressing through the disk 20 and the link pressing member 33 and the pressing spring 31 is a disk 20 is formed between 40 the side plate 10 is formed of the oil passage hole 11; Means associated with the disk 20 through a link 40 to pivot around the arbitrary point of the plate 10, by rotating the link 40 is connected to the pressure element the disk 20, which the plate ( drive means 60 for the disc 20 to open and close the passage hole 11 to ensure that sliding movement draw an arc in the plane of 10); Is disposed on the movement path of the disk 20, each time a provided with a projection (51) engaged with the teeth of the sprocket disc (20) through the rotation of the link of the disk 20 moves the disc (20 ) sprocket teeth are engaged with the projections stick sprocket 50 to which the disk 20 so that rotation of; It characterized in that it comprises a.
