The sealing member 130 forms a first flow hole 132-1 communicating with the fluid container 134 at a bent portion between the wing 132 and the restriction protrusion 133-3, so that the fluid can flow into the fluid container 134 even if the wing 132 is in contact with the inner side surface of the body 131 through the tube 200 inserted into the interior of the body 131.
The first flow hole 132-1 of the wing 132 is formed in a semicircular shape, and a protrusion 133 protruding inward is formed at an inner side surface of the body 131 contacting the wing 132, and a second flow hole 133-1 corresponding to the semicircular shape of the first flow hole 132-1 is formed at the protrusion 133, so that an end of the wing 132 contacts the protrusion 133 through a pipe 200 inserted into the body 131, and thus the first flow hole 132-1 and the second flow hole 133-1 are formed in a semicircular shape.

As shown in fig. 1 to 3, the coupling 100 of the present invention connects adjacent two pipes 200 in a longitudinal direction and maintains water-tightness, and a plurality of divided circular arc segments 110 are combined in a ring shape.
Plate-shaped flanges 120 are formed at both ends of the respective segments 110 so as to be coupled between the segments 110 to each other, and bolt holes 121 for passing through the flanges 120 are formed at the flanges 120.
When the ends of the pair of pipes 200 are located in the hollow holes formed by the plurality of annularly connected segments 110, the pair of pipes 200 are connected to each other by inserting bolts 140 into bolt holes 121 formed in flanges 120 that contact each other and then fastening them with nuts 150
A sealing member 130 is inserted to be mounted on an inner circumferential edge of the coupler 100 to maintain water-tightness.
Fig. 4 is a perspective view showing a sealing member of a coupling according to the present invention, fig. 5 is a perspective view of a sealing member installed at the coupling of the present invention, cut vertically, fig. 6 is a partial detailed perspective view of the sealing member installed at the coupling of the present invention, and fig. 7 is a vertical sectional view of the sealing member installed at the coupling of the present invention.
As shown in fig. 4 to 7, the sealing member 130 includes a body 131 having a hollow body shape and a wing 132 bent toward an inner peripheral edge of the body 131, and a fluid receiving part 134 for receiving a fluid is formed between the wing 132 and an inner side surface of the body 131.
At the end of the wing 132 is formed a restriction protrusion 133-3 protruding toward the center of the sealing member 130 such that the ends of the pipe 200 inserted into both ends of the sealing member 130 are inserted to be in contact with the restriction protrusion 133-3 of the sealing member 130, whereby water tightness and an insertion degree are predetermined.
The sealing member 130 forms a first flow hole 132-1 communicating with the fluid container 134 at a bent portion between the wing 132 and the restriction protrusion 133-3, so that the fluid can flow into the fluid container 134 even if the wing 132 is in contact with the inner side surface of the body 131 through the tube 200 inserted into the interior of the body 131.
The first flow hole 132-1 of the wing 132 is formed in a semicircular shape, a protrusion 133 protruding inward is formed on an inner surface of the body 131 contacting the wing 132, and a second flow hole 133-1 corresponding to the semicircular shape of the first flow hole 132-1 of the wing 132 is formed on the protrusion 133.
Accordingly, the end of the wing 132 is contacted with the protrusion 133 through the tube 200 inserted into the inside of the main body, so that the first and second flow holes 132-1 and 133-1 are formed in a semicircular shape.
Describing the sealing member 130 in more detail, the sealing member 100 accommodates the inside of the tube 200 with a hollow hole to prevent fluid flowing inside the tube 200 from leaking to the outside, thereby preventing leakage of the tube 200.
In particular, the sealing member 100 of the present invention is formed with wing parts 132 bent toward the inner peripheral edge of the body 131 at both ends of the body 131 in a hollow shape, and a fluid receiving part 134 for receiving a fluid is formed between the wing parts 132 and the inner side surface between the body 131.
That is, the wing 132 is integrally formed at one end of the body 131, and the other end is bent toward the inner peripheral edge of the body 131, and a space portion, which is referred to as a fluid accommodating portion 134, is formed between the wing 132 and the inner side surface of the body 131 to allow fluid leaking from the pipe 200 to be accommodated therein.
At this time, even if the end of the wing 132 is in contact with the inner side of the body through the tube 200 inserted into the body 131, the first flow hole 132-1 communicating with the fluid container 134 is formed at the end of the wing 132 so that the fluid is introduced into the fluid container 134.
The first flow hole 132-1 of the wing 132 is formed in a semicircular shape, a protrusion 133 protruding inward is formed on an inner surface of the body 131 contacting the wing 132, and a second flow hole 133-1 corresponding to the semicircular shape of the first flow hole 132-1 of the wing 132 is formed on the protrusion 133.
Accordingly, the end of the wing 132 is contacted with the protrusion 133 through the tube 200 inserted into the inside of the main body, so that the first and second flow holes 132-1 and 133-1 are formed in a semicircular shape.
The plurality of first and second flow holes 132-1 and 133-1 are spaced apart at predetermined intervals in the circumferential direction of the wing 132 and the protruding protrusion 133 so that the fluid is easily introduced into the fluid receiving part 134.
In addition, a plurality of shoulders 132-2 are formed on the outer side surfaces of the wings 132 contacting the tube 200, the shoulders 132-2 being inclined toward the central portion of the inner circumference of the sealing member 100 to prevent the wings 132 from being folded outward when the tube 200 is inserted.
The sealing member 100 of the present invention is preferably made of synthetic rubber or synthetic resin.
When the fluid flowing into the pipe 200 is leaked by the sealing member 100 and the fluid flows into the fluid container 134 through the first flow hole 132-1, a fluid pressure is formed inside the fluid container 134 so that the wing 132 is firmly attached to the outer side surface of the pipe 200 to prevent the pipe 200 from leaking water.
And, restricting protrusions 133-3 are protrudingly formed at the end portions of the respective wings 132 toward the central portion of the sealing member 130, the restricting protrusions 133-3 being in close contact with each other by the respectively inserted tubes 200, so that the water tightness of the tubes 200 is more maintained.
On the other hand, the body 131 is continuously formed of a first body 131-1 having a large thickness and a second body 131-2 having a small thickness with respect to the first body 131-1, and a plurality of bellows portions 131-3 are formed in a circumferential direction at an outer side surface of the body 131, thereby withstanding fluid pressure occurring when fluid leaks from the pipe 200.
As described above, the coupling according to the present invention is mounted with the sealing member having the fluid receiving part for receiving the initially leaked fluid so that the fluid is not leaked to the outside, and in addition, when the initially leaked fluid is received in the fluid receiving part, the pressure increase caused by the fluid is more sealed, so that the fluid leakage can be continuously prevented, and in addition, since the inner peripheral edge of the sealing member is provided with the restricting protrusion protruding in the circumferential direction, the respective tubes inserted to both ends of the coupling can be accurately seated, thereby facilitating the connection between the tubes.
