Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wiper valve having an eccentric disc,

The present invention relates to a disk of a wiping valve, and more particularly, to a disk of a wiping valve, in which one side circumferential surface of a disk is eccentrically machined, and a thickness of a packing member fitted to one eccentric surface of the disk is reduced by eccentric machining The present invention relates to an eccentric type disk of a water-supply valve which can be used for a longer time without replacement even if wear of the packing member occurs.

In general, a wiping valve is a valve installed in a water pipe embedded in an underground and used for supplying and shutting off water. The valve serves to supply and shut off water while rotating the cylindrical disk. In addition, It is possible to structure without part, so that it prevents the deposition of various foreign substances such as sand, soil,

That is, the drain valve is formed with a concave groove portion for supporting the rotation shaft of the disk on the inner bottom surface of the valve body. However, even if the water is purified and filtrated, the water contains a small amount of gravel, soil, sand, And after a certain period of time it is deposited without flowing despite the strong currents. Therefore, due to foreign matter deposited on the recessed groove, the disc sheet and the valve body sheet are not in close contact with each other, resulting in poor watertightness, resulting in a great loss of tap water.

In order to solve the above-mentioned problem, a disc having a cylindrical shape has been developed. In this case, a vertical shaft is tightly installed in a valve body having inlet and outlet ports formed on both sides thereof.

The cylindrical disc is formed in such a manner that a water hole corresponding to the inner diameter of the valve body is formed opposite to both sides to open the channel in a range of 0 to 90 degrees and a rotary shaft is formed at the center of the bottom, And is rotatably installed in a tubular bearing.

A packing ring sheet tube is inserted into the inlet and outlet of the valve body so that the packing ring is in close contact with the outer wall surface of the cylindrical disk at the tip thereof. The packing ring sheet rotates while being in contact with the packing ring when the cylindrical disk rotates, Structure.

A typical prior art related to the above-mentioned cylindrical disk is disclosed in Korean Patent Publication No. 10-1480433 (filed on May 22, 2013, filed on Jan. 2, 2015, A cylindrical wiper valve which can be easily coupled).

The prior art includes a valve body having an inlet port and an outlet port formed on both sides thereof and having a mounting hole formed at an upper portion thereof and having a tubular bearing formed at a recessed bearing portion formed at the bottom surface thereof, And a water supply hole fixed to a lower end of the vertical shaft and rotatable inside the valve body and corresponding to an inner diameter of the valve body is formed opposite to both sides of the valve body, And a packing ring coupled to the cylindrical disc to maintain watertightness between the valve body and the cylindrical disc, wherein the cylindrical disc is provided with a packing ring on the circumferential surface between the water holes, Wherein the packing ring is formed with at least two-thirds of the cross-sectional area And that a technical aspect that is fitted to be buried in the fitting groove.

This prior art technique enhances the adhesiveness of the packing ring fitted to the cylindrical disc to prevent the packing ring from easily falling off the cylindrical disc, thereby prolonging the life of the product and facilitating the prevention of water leakage between the cylindrical disc and the valve body It is obvious that it is a useful invention.

However, in the above prior art, since the packing ring sealing the inlet and the outlet is rubbed in a state of being closely adhered to the axial flow of the valve body due to frequent operation of the valve, the wear phenomenon can not be avoided. As a result, And it causes a lot of inconvenience to maintenance due to frequent replacement work.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following detailed description, exemplary embodiments of the present invention will be described in order to accomplish the above-mentioned technical problems. And other embodiments which may be presented by the present invention are replaced by descriptions in the constitution of the present invention.

FIG. 1 is a view showing the entire configuration of an eccentric disc of a wiping valve according to a preferred embodiment of the present invention, FIG. 2 is a view showing a flat section of FIG. 1, and FIG. 3 is a cross- Sectional view showing the main configuration of the eccentric disk.

As shown in FIGS. 1 to 3, the water wash valve 100 is divided into a valve body 10 and an eccentric disk 20.

The valve body 10 constitutes the outer shape of the valve and includes inlet and outlet ports 12 and 14 through which fluids are passed to both sides of the valve body 10 and connects the inlet and outlet ports 12 and 14 to the center A chamber 16 is formed.

The eccentric disk 20 is inserted into the chamber 16 of the valve body 10 and connected to the valve body 10 through a connection hole 18 formed at the center thereof in the forward and reverse directions, And opens and closes the valve body 10 by connecting and disconnecting the inlet and outlet ports 12 and 14 with each other.

The eccentric disc 20 is provided at its upper end with a rotary shaft 22 and a handle is mounted on the rotary shaft 22 so that the eccentric disc 20 inserted in the chamber 16 of the valve body 10 , And performs reverse rotation operation.

First and second insertion grooves 24 and 26 having a circular ring shape are formed on both circumferential surfaces of the eccentric disc 20 and first and second insertion grooves 24 and 26 are formed in the first and second insertion grooves 24 and 26, The first and second ring portions 32 and 42 of the packing members 30 and 40 are fitted, respectively.

The first and second packing members 30 and 40 release the connection of the inlet and outlet ports 12 and 14 of the valve body 10 by the rotation operation of the eccentric disc 20, The inlet and outlet ports 12 and 14 of the valve body 10 are sealed to maintain the watertightness of the valve body 10 and the eccentric disc 20.

The first packing member 30 is a member provided on one side of the eccentric disk 20 and closes the inlet 12 of the valve body 10 and includes a first ring portion 32 And a first cover (34) provided on the inner surface of the first ring part (32) and blocking the inlet (12).

The second packing member 40 is a member installed on the other side surface of the eccentric disc 20 and closes the outlet 14 of the valve body 10. The second packing member 40 has the same shape as the first packing member 30 A second ring portion 42 preferably having a circular ring shape and a second cover 44 provided on the inner surface of the second ring portion 42 and blocking the outlet 14.

The thickness T1 of the first cover 34 of the first packing member 30 is formed to be relatively thick compared to the thickness T2 of the second cover 44 of the second packing member 40. [ This is because the first cover 34 of the first packing member 30 continuously rubs against the inner circumferential surface of the chamber 16 of the valve body 10 by the operation of the valve, 34) can be used for a longer time without replacement. Particularly, in the present invention, not only the first and second covers 34 and 44 of the first and second packing members 30 and 40 are thickened but the first cover 34 is thickly formed, And the leakage of the fluid can be prevented even if only one of the inflow and outflow ports 12 and 14 is tightly sealed without sealing the outflow ports 12 and 14 all together.

The eccentric disc 20 is not a planar disc shape but has one side circumferential surface 20a of the disc 20 on which the first packing member 30 is fitted, So that the radius R1 from the center of the disk 20 to the one circumferential face 20a is relatively larger than the radius R2 from the center of the disk 20 to the other circumferential face 20b of the disk 20 .

That is, since the thickness T1 of the first cover 34 of the first packing member 30 is relatively thick compared to the thickness T2 of the second cover 44 of the second packing member 40, The first cover 34 and the inner circumferential surface of the chamber 16 of the valve body 10 are more strongly rubbed by the thickness of the first cover 34 so that the rotation of the disk 20 provided with the first packing member 30 The first side surface 20a of the eccentric disk 20 is eccentrically machined and the first side surface 20a of the eccentric disk 20 is fitted to the eccentric side surface 20a of the eccentric disk 20, The thickness T1 of the first cover 34 of the member 30 is reduced by the eccentric machining of the eccentric disc 20 (that is, the width of the eccentric disc 20 ) Of the first packing member 30 so that the first cover 34 of the first packing member 30 is abraded due to friction, It is possible to use the cover 34 for a longer time without replacement by the increased thickness T1 of the cover 34. [

Further, when the second packing member 40, which is relatively thin compared to the first packing member 30, is worn during use, the second packing member 40 is taken out, And the first packing member 30, which is a new product, is inserted into the first insertion groove 24 of the eccentric disc 20 to use the first packing member 30.
