The present invention relates to a technique for relocating a pipe without removing a fluid from the center in relocating a fluid pipe that is already installed and in use. In particular, the present invention provides a technology for blocking a fluid flowing through a pipe through a hole drilled in the pipe. The present invention relates to a pipe fluid breaker for relocating pipes and a method for relocating a fluid pipe using the same.

In general, the endless relocation method of the fluid pipe is a method for relocating the fluid pipe while the fluid pipe is already installed and in use, by continuously supplying the fluid pipe without blocking the fluid at the center to reduce the damage of other users. In other words, if there are many existing customers, such as city gas pipes or water pipes, when the pipes are installed for new customers, many users experience inconveniences. This method is used to minimize the damage to customers. In addition, when the pipe is buried in the middle of the road, such as when the road is broken, it is a method used to cut the damaged part without connecting the fluid in the center to connect to the new pipe.

As such a technique, the existing pipe cutting method disclosed in Japanese Patent Laid-Open No. 1999-325377 is known. The existing pipe cutting method is a method of cutting both ends of the portion to be branched in the existing pipe, and branching by installing a branch pipe to the pipe cut by using a punching valve.

Blocking the fluid flow. At this time, the pressure of the gas supplied to the pressure ball 15 or the pneumatic cylinder 17 is preferably greater than the pressure of the fluid flowing through the pipe (50).

The fluid blocker for pipe of the present invention configured as described above and the method of discontinuing the fluid pipe using the same, relocate to another place safely without moving the fluid flow from the center to the fluid pipe in which the fluid flows, or to a new pipe Make sure you can connect.

First, holes are drilled in the pipes 50 at positions away from each other by a predetermined distance. That is, the branch saddle 20 is mounted and fixed to the pipe 50, and the valve body 30 including the shutoff valve 35 is connected to the branch saddle 20. Subsequently, after attaching the punching device 40 to the upper side of the valve body, a hole is drilled in the pipe 50, and after the cutting piece is removed using the punching device 40, the punching device 40 is replaced with a valve body ( Remove from 30). Therefore, almost no cutting pieces remain in the inside of the pipe 50, which means that the internal pressure ball 15 is not damaged during the input of the fluid circuit breaker 10.
