The saddle 10 includes an upper coupling 11 and a lower coupling 12. The upper coupling 11 and the lower coupling 12 have an inner circumferential surface of a substantially semi-circular shape, and when the upper coupling 11 and the lower coupling 12 are disposed above and below the water pipe p, respectively, 10 surrounds the water pipe p.

Flange portions 14 are formed on both sides of the upper coupling 11, respectively, and flange portions 15 are formed on both sides of the lower coupling 12, respectively. In addition, the coupling holes 16 are formed in the pair of flange portions 14 of the upper coupling 11, and the pair of flange portions 15 of the lower coupling 12 are similar to the upper coupling 11. The engaging hole 17 is formed. With the upper coupling 11 and the lower coupling 12 arranged up and down, bolts b are fitted into the coupling holes 16 and 17 of the upper coupling 11 and the lower coupling 12. The upper coupling 11 and the lower coupling 12 are coupled to each other by being fastened to the holding nut n.

In addition, a through hole 13 is formed in an upper portion of the upper coupling 11. A female screw thread 18 is formed on the inner circumferential surface of the through hole 13. As shown in FIG. 2A, a hollow fastening tube 20 is coupled to the female screw thread 18. The hollow portion 25 of the fastening tube 20 is disposed coaxially with the through hole 13 of the saddle 10 and communicate with each other. However, the fastening tube 20 may be formed separately from the upper coupling 11 as shown in FIG. 2A, but may be integrally formed with the upper coupling 11 as shown in FIG. 2B. The present invention includes both the case in which the fastening pipe 20 is formed integrally with the upper coupling 11 and in the case of being separated (screwed).

 As shown in Figure 2a, in the form separated from the upper coupling 11, the fastening pipe 20 is formed in a hollow, the male thread 22 is formed in the lower outer peripheral surface, the male thread 22 is It is screwed into the female thread 18 on the inner circumferential surface of the saddle through hole 13. Thread 23 is also formed on the outer circumferential surface of the fastening tube 20, which is for coupling the valve 80.

As shown in FIG. 2A, when the fastening tube 20 and the upper coupling 11 are formed separately, the saddle 20 and the upper coupling 11 to waterproof between the saddle 60 and the fastening tube 20. O-ring 29 is sandwiched between the < RTI ID = 0.0 > In addition, the inner circumferential surface of the fastening tube 20 is formed with a concave fitting groove 28. The fitting groove 28 is disposed in an annular shape along the inner circumferential surface of the fastening pipe 20.

On the other hand, the fluid pipe closing cap 50 is for closing the perforated hole (h) perforated in the fluid pipe for repair, replacement, etc., the hollow of the through hole 13 and the fastening pipe 20 of the saddle 10 It fits in the part 25 and is combined.

The fluid pipe closing cap 50 is made of a rubber material and has a body portion 51 having a substantially cylindrical shape. A groove portion 53 is formed in the upper center of the main body portion 51. This groove part 53 is open toward the upper surface of the main body part 51. The lower surface 54 of the main body 51 is formed in a curved surface so as to correspond to the shape of the drilling hole h of the water pipe.

In addition, the main body portion 51 is provided with a locking portion 52 protruding from the outer circumferential surface of the main body portion. The locking portion 52 is disposed in an annular shape along the outer circumferential surface of the body portion 51 and is integrally formed with the body portion 51.

The locking portion 52 has a small degree of protruding from the lower portion of the main body portion 51, and the degree of protruding from the upper portion of the locking portion 52 gradually increases. The cross section of the engaging portion 52 is formed in an inclined triangular form.

 In addition, the locking portion 52 is made of a rubber material is compressed in accordance with the application of an external force, and when the external force is released, it is restored to its original state. In particular, since the upper portion of the locking portion 52 is more protruded than the lower side, the upper portion of the locking portion 52 tends to retract toward the main body portion 51 side. That is, when only a slight external force is applied, deformation of the shape in which the upper surface 58 of the locking portion 52 is folded to be in close contact with the outer circumferential surface of the main body 51 occurs easily, whereas the inclined surface of the locking portion 52 is reversed ( Deformation of the form in which 59 is folded and in close contact with the outer circumferential surface of the main body portion 51 is hardly caused. Even if an external force is applied and a deformation of the latching portion 52 is retracted, the original force is restored when the external force is released.

Hereinafter, a use example of the fluid pipe blocker 100 having the above configuration will be described in more detail.

The saddle 10 having the above-described configuration is installed on both sides of the water pipe p with a section requiring repair therebetween. That is, the upper coupling 11 is disposed above the water pipe p, and the bolt b and the nut n are fastened to each other while the lower coupling 12 is disposed below the water pipe p. , Saddle 10 is wrapped around the water pipe (p) to be combined. The fastening pipe 20 is coupled to the upper portion of the upper coupling 11 of the saddle 10, or the fastening pipe 20 is used to form the upper coupling 11 integrally. The fastening pipe 20 is equipped with a valve (80).

The valve 80 is hollow and has a thread formed on its inner circumferential surface, which is fastened to a thread 23 on the outer circumferential surface of the fastening pipe 20. In the valve 80, the disk 82 is movable to open and close the hollow portion, and a lever 83 or the like for moving the disk 82 is provided. The valve can take a variety of forms including, for example, a ball valve.

After connecting a puncher (not shown) to the valve 80 in the above state, the water pipe (p) is drilled to form a punching hole (h). The water pipe (p) is composed of a main pipe (i) of steel material and a lining (c) surrounding the inner circumferential surface of the main pipe (i). The lining (c) is generally made of a material such as cement, so that water is in contact with the main building (i) to prevent the main building (i) from corroding.

When the drilling hole (h) is formed, the blocking device is inserted through the drilling hole (h) to block the flow of water, and then the construction of the problematic section is performed. If the dismantling device is dismantled after the construction is completed, the state becomes as shown in FIG. In the state (a) of FIG. 3, in the state in which the repair work of the water pipe p is completed, the tap water flows and the valve 80 is closed so that the tap water is not ejected through the drilling hole h.

In the above state, the fluid pipe closing device 50 according to the present invention is inserted to close the drilling hole h. Prior to connecting the inserter 90 to the valve 80, the lower end of the rod 97 of the inserter 90 is pressed into the groove 53 of the fluid tube closure device 50. The rod 97 is raised and lowered by the action of the gear 91 in the inner hollow portion 92 of the insertion device (90). When the fluid pipe closing device 50 is connected to the valve 80 in a state of being fitted to the rod 97, the fluid pipe closing device 50 is in the state of FIG.

When the valve 80 is opened in the above state and the rod 97 is lowered, the fluid pipe closing cap 50 passes through the hollow part of the valve 80 and the hollow part 25 and the water pipe p of the fastening pipe 20. It is fitted into the drilled hole (h) of, and is brought into the state as shown in FIG.

The outer diameter of the locking portion 52 of the fluid pipe closing cap 50 is larger than the inner diameter of the valve 80 and the inner diameter of the fastening pipe 20. Accordingly, when the rod 97 is lowered, the locking portion 52 of the fluid pipe closing cap 50 is caught on the upper surface of the valve 80, but as described above, the locking portion 52 is made of a compressible rubber material. In addition, it is made of a triangular shape, in particular, the upper surface 58 is compressed and folded to be in close contact with the outer circumferential surface of the main body portion 51 can easily occur. Thus, the engaging portion 52 is compression-deformed may be sequentially inserted along the inner peripheral surface of the valve 80 and the inner peripheral surface of the fastening pipe 20.

When the fluid pipe closing cap 50 descends to a certain depth, the locking portion 52 is positioned in the fitting groove portion 28 formed on the inner circumferential surface of the coupling tube 20, and the body portion 51 in the fitting groove portion 28. Since the inner circumferential surface of the expansion force is released, the external force on the compressed locking portion 52 is released, and the locking portion 52 returns to its original state, and the locking portion 52 is caught by the fitting groove portion 28. This state is shown in Fig. 3C.

In the state of FIG. 3C, the rod 92 of the insertion apparatus 90 is raised to separate the rod 92 and the fluid pipe closing cap 50. That is, since the rod 92 is forcibly fitted into the groove portion 53 of the fluid pipe closing cap 50, when the rod 92 is raised while the locking portion 52 is fitted into the fitting groove portion 28, the rod 92 is raised. 92 is detachable from the groove portion 53 of the fluid tube closing cap 50.

Finally, when the insertion device 90 and the valve 80 are separated, the water pipe closing operation using the fluid pipe blocker 100 according to the present invention is completed as shown in FIG. In this state, since the hollow portion 25 of the drilling hole h and the fastening pipe 20 is blocked by the fluid pipe closing cap 50, the tap water flowing through the water pipe p cannot be ejected to the outside.

In addition, even if the water pressure of the tap water is high, the fluid pipe closing cap 50 is not separated to the outside by the water pressure. That is, in order for the fluid pipe closing cap 50 to leave the fastening pipe 20, the locking portion 52 must be completely turned upside down, and the locking portion 52 is more protruded upwards, so that the upper surface 58 Although it is easy to be folded and compressed toward the main body 51, it is impossible to completely invert the inclined surface 59 so as to be in close contact with the main body 51.

In this state, even if there is no auxiliary device such as screwing a separate lid to the outer peripheral surface of the fastening pipe 20, the fluid pipe closing cap 50 can completely close the water pipe (p) the drilling hole (h). .

Although the outer diameter of the fluid pipe closing cap 50 is shown to be the same as the inner diameter of the drilling hole (h) and the fastening pipe 20, in reality, the outer diameter of the closing cap 50 is made slightly larger, and thus the fluid pipe closing cap ( 50 is fitted in a slightly compressed state when the hole (h) and the hollow portion 25 of the fastening pipe 20 is fitted, so that the hole (h) and the fastening pipe 20 and the fluid pipe closing cap ( 50) are completely sealed.

On the other hand, since the fluid pipe closing cap 50 is in close contact with the main pipe (i) of the steel material of the drilling hole (h), it is possible to prevent the water supply contact with the main pipe (i) to corrode the main pipe (i).

Reference numeral 81, which is not described, is a thread for connecting the perforator (not shown) and the inserting device 90 to the valve 80.

Although the present invention has been described with reference to the embodiments shown in the accompanying drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. There will be. Accordingly, the true scope of protection of the invention should be defined only by the appended claims.
