The present invention relates to a disk valve, and more particularly, to a disk valve capable of opening and closing in a sliding manner, a sliding disk capable of improving the effective period of use of the disk by improving the uniform wear of the disk, Valve.

Generally, a gate valve is a general term for a valve in which a valve disk vertically closes a fluid passage to open and close and a fluid flow is in a straight line, and is designed to control the flow of fluid in one direction. Thereby opening and closing the flow path of the fluid.

Such a gate valve can be applied to both piping in which fluid pressure loss is small, fluid pressure loss is small, flow is relatively easy to manufacture, low pressure, high pressure, And the distance between the attachment surfaces is short, so that the handle operation is light and the two-side sealing is possible, which is advantageous in that there is no direction when the valve is installed.

The gate valve may be a wedge gate valve, a double disk gate valve, a parallel slide gate valve, a venturi gate valve, port gate valve, and through conduit gate valve.

A wedge gate valve is a wedge-shaped gate valve whose valve disc is also referred to as a simple gate valve. A double disc gate valve is a combination of two valve discs and is a gate valve that presses the valve disc by the thrust of the valve disc and applies pressure to the valve seat surface at the outlet and inlet.

The venturi port gate valve is a gate valve which is constituted by a combination of two valve discs parallel to each other and which gives a surface pressure to the valve seat surface on the outlet side by the pressure of the fluid, And the through-conduit gate valve is a gate valve having a valve disc structure opened by a passage having the same size as that of the passage.

In addition, the pressing portion 30 is configured to press in both directions, and the disk is coupled to one side and the other side of the pressing portion 30, so that the sliding disk valve 100 can have a dual simultaneous opening and closing structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

1 is a cross-sectional view showing a state in which a sliding disk valve 100 (hereinafter referred to as 'valve 100') according to the present invention is installed in a channel.

The valve 100 has a flange for connecting the two pipes to each other to control the flow of the fluid and has a flange for connecting the pipe to both sides of the pipe. A disk 20 for blocking or opening the flow passage hole 11 and a pressing spring 33 connected to the disk 20 by means of a pressure spring 31, A drive unit 60 connected to the pressing unit 30 to rotate the disk 20; and a sprocket stick 50. The sprocket stick 50 is formed of a metal plate.

Specifically, the valve 100 is provided with a diaphragm 10 in which a flow hole 11 is formed at one end of a tube, and the flow hole 11 is opened and closed in a sliding manner to control the flow of fluid. A disk 20 having a sprocket for opening and closing the flow passage hole 11 of the disk 10 and a disk 20 connected to the disk 20 so as to face the disk 10 on which the flow passage hole 11 is formed The disk 20 is rotated about an arbitrary point of the diaphragm 10 and connected to the pressing portion 30 to slide the disk 20 in a circular arc on the plane of the diaphragm 10, And a protrusion 51 disposed on the movement path of the disc 20 and meshed with the teeth of the sprocket so as to move the disc 20, And a sprocket stick 50 that rotates the disc 20 whenever the disc 20 rotates.

Fig. 2 is a cross-sectional view taken along the line AA in Fig. 1, showing the main parts (the diaphragm 10, the disk 20 and the sprocket stick 50) of the valve 100, to be.

1 to 3, a diaphragm 10 is provided with a flow passage hole 11. The flow passage hole 11 is opened and closed by the disk 20, and in order to open and close the disk 20, The portion 30 and the driving means 60 are required. A sprocket stick 50 is provided to prevent the disk 20 from being locally abraded during frequent friction between the disk 20 and the diaphragm 10 in the vicinity of the flow hole 11 due to the opening and closing operation of the disk 20, .

The drive means 60 includes a link 40 connecting the rotation center axis of the drive means 60 and the disk 20 so that the disk 20 is rotated by the rotation of the drive means 60, Or the channel hole 11 is opened. As the operator manually rotates the manipulation board connected to the rotation center axis, the driving unit 60 can transfer the rotation of the manipulation unit 60 to the disk 20 and rotate the disk as shown in FIG. The sprocket of the disc 20 is interfered with the protrusion 51 of the sprocket stick 50 disposed on the moving path of the disc 20 to rotate the disc 20 Thereby preventing the disc 20 from being unevenly worn. 1, the connection between the disc 20 in close contact with the diaphragm 10 and the urging portion 30 for urging the disc 20 by the diaphragm 10 is connected to the disc 20 by the urging portion 30, And the diaphragm (10). By using such a connection method, irregular rotation can be generated in the disk 20 when the disk 20 is moved by the driving means 60, and this can be used for preventing the occurrence of the uneven wear.

Even if the position A is returned again, It is possible to prevent the occurrence of the uneven wear phenomenon.
The rotation of the drive means is transmitted to the disk via a link connected to the drive means. When the disk to which the rotation of the drive means is transmitted is rotated, a sprocket tooth- There is no configuration for stopping the disk when the disk is rotated through the projecting portion of the sprocket stick, so that the disk is irregularly rotated.
As a result, the sprocket of the disk is positioned at a position other than the position where the sprocket is brought back to the point of first contact with the projection, thereby preventing the occurrence of the uneven wear phenomenon.

Meanwhile, the present invention is characterized in that the number of protrusions 51 is set to be at least (at least) the number of protrusions 51 in order to study the prevention of effective anti-abrasion by giving a gap difference between a first worn portion and a next worn portion by a single reciprocating More than one can be formed.
When the disc is formed in a double concurrent opening / closing structure, a guide tube of the pressing portion 30 formed between the link and the disc is formed on both sides, and the pressing spring is embedded in both sides in the guide tube, And presses the disc formed to correspond to the other side.
Since the disc is coupled so as to correspond to both sides of the link, the discs on both sides can be rotated at the same time due to the rotation of the link.
