Description

AN END PACKING FOR PIPE}

The present invention relates to a finishing packing for piping, and more particularly, to a finishing packing for piping which is improved to prevent the fluid in the piping from leaking by closing the end of the piping.

In order to construct a fluid line having a long length for transporting or supplying a raw material or the like, piping having a predetermined length is connected to each other. A flange is formed at both ends of a pipe to be connected, And tightly fastened by means of interrupting means composed of bolts and nuts.

Since the flange is made of the same metal material as the pipe, a packing (or a gasket) is interposed between the flange and the flange as means for preventing the leakage of the fluid.

Conventionally, many kinds of packing for preventing the leakage of the fluid have been developed and used in connection with the connection portion of the piping. A typical example will be described with reference to FIG.

The packing 1 to which the conventional technique is applied is provided with a packing body 4 having the same diameter as the flange 3 of the pipe 2 and made of rubber or urethane and the center of the packing body 4 A flow-through hole 5 having the same inner diameter as that of the pipe 2 is formed.

The packing body 4 is formed with the same number of fastening holes 7 as the fastening holes 6 formed in the flange 3 so as to be fastened with the intermittent means 8 composed of bolts and nuts , And the packing body (4) around the fastening hole (6) is formed with concave / convex parts as a means for enhancing airtightness.

Patent Application No. 10 - 2000 - 0079805 Patent Application No. 10 - 2007 - 0092353 Utility Model Registration No. 20 - 0252274 - 0000 Registered Utility Model No. 20 - 0428379 - 0000

The above-mentioned conventional packing can prevent the fluid from leaking through the space between the flange and the flange when it is interposed in the area where the pipe is connected, but it can not be used at the end of the pipe.

Of course, it is possible to prevent leakage of the fluid through the finishing at the end of the piping, but it is often necessary to open the piping for internal inspection and measurement to remove foreign substances such as scales accumulated in the piping In this case, the finishing plate 10 is intermittently fastened to the flange at the end of the pipe with bolts and nuts, thereby selectively opening and closing the pipe.

In this case, the packing is interposed between the flange and the finishing plate to prevent the fluid from leaking. Since the packing is the same as the packing used in the middle of the pipe, the fluid is directly connected to the center of the finishing plate .

When the fluid is a general fluid, it does not greatly affect the finishing plate or the piping. However, in the case of a fluid such as a chemical, since the direct connection with the finishing plate is made through the fastening hole formed at the center of the packing, Or damage.

When the fluid in the piping damages the finishing plate through direct connection with the finishing plate, the durability of the finishing plate is weakened and the finishing of the end of the finishing pipe can not be faithfully performed. Since the rubber packing is also highly susceptible to damage, it is not possible to eliminate the phenomenon of the fluid being pinched between the flange and the finishing plate.

If a harmful fluid leaks through the gap between the flange and the finishing plate, it will pollute the surrounding air as well as the soil and the water quality. Especially, if the water and soil penetrate deeply, the water and soil pollution as well as the secondary damage And there is a high possibility that natural disasters may occur through such a problem.

In order to solve the above-mentioned problems, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a packing body made of rubber material in the form of a disc, protruding pieces formed on the edges of the packing body, An intermediate airtightness layer formed on the outer periphery of the packing body and having one or more leak delay rings formed of a plurality of leakage delay protrusions on the inner side of the outer airtight layer, An inner airtight layer having one or more annular rims formed on the inner side of the intermediate airtight layer and a reinforcing plate further attached to a boundary position between the inner airtight layer and the middle part of the packing body and the intermediate airtight layer;

It is possible to prevent the leakage of the fluid and to prevent the finishing plate from being damaged by the fluid while facilitating the coupling and separation of the finishing packing.

This design provides an improved packing at the end of the piping to maintain a stable airtight condition regardless of the type of fluid inside the piping, prevent leakage of the fluid to prevent environmental pollution, Improving the life and quality of the packing by performing the improvement.
