Hereinafter, a packing for a pipe coupling and a coupler using the same according to the present invention will be described in detail with reference to the accompanying drawings.

A feature of the packing according to the present invention is that the pipe can be easily fitted to the packing when the pipe is fitted to the packing, so that no fluid leaks between the packing and the pipe.

The packing 10 of the present invention, as shown in Figure 4, the inner peripheral surface is symmetrical to each other and the contact wing (1) is formed, is installed in the pipe and the pipe connecting portion to prevent the leakage of fluid In (10), characterized in that formed on the one side of the protrusion (2) formed on the part facing the contact wing (1) by forming a contraction space (3) that can be contracted.

The shrinkage wing 1 is installed to be inclined as shown, and the inclined direction is a direction inclined to the inside of the packing, and as shown in FIG. 6, when the pipe is fitted into the packing 10, In close contact with the outer surface to prevent fluid from leaking between the inner circumferential surface of the packing and the outer circumferential surface of the packing, as shown in FIGS. 5 and 7, the pressure passage 11 is formed between the shrinkage wing 1 and the inner wall of the packing body.

As described above, the pressurized flow path 11 is filled with the fluid and expands by the pressure of the filled fluid so that the close wing 1 is tightly adhered to the pipe.

At the end of the contact blade (1) is formed a tip portion (1a) having a sharp cross section as shown, the tip portion (1a) formed at the end of the contact blade (1) as shown in FIG. Adhering to the pipe, there is no gap between the pipe and the end of the contact blade, thereby preventing the fluid from smearing between the contact blade and the pipe.

The contraction space 3 formed on one side of the protrusion 2 is formed in the shape of a groove that is directed toward the contact wing 1 on the opposite side of the portion where the contact wing 1 is formed.
