Generally, a water pipe consists of a main pipe of a large diameter for transferring large-capacity constants over a long distance, and a branch pipe branched from the main pipe and supplying the water by short distance transportation such as home and office.

In this branching branch, a valve for the supply of water is always provided so that the interception of the water can be performed, so that the operation is facilitated by the number of steps when replacing the aged or broken water pipe.

In the conventional method using such a supply valve, all the supply valves connected to the water pipe at the replacement point are shut off and work is performed in a state where water is not supplied to the water pipe to be replaced.

Therefore, there is a problem that the number of steps is generated in a considerably large area where the shutoff valve is closed.

Such a fluid shut-off device utilizes a fluid shut-off head having blocking heads of various shapes and configurations, such as a pivoting blocking head, a folding blocking head, a deflecting plate blocking head, So that it plays the same role as a supply valve at any point in a variety of pipelines such as a water supply pipe.

However, in the conventional end-flow water shut-off system, since the shape and structure of the shut-off head are formed in a disc shape, there is a problem that the shut-off head must move in one direction in the piping. There is a problem that it is not smoothly performed, and there is a problem that the structure is relatively complicated due to the structure for moving the blocking head.

Particularly, there is a problem that a shaft for moving the blocking head due to a high water pressure is generated, a separate device for bypassing is required, and additional work is required.

In addition, the conventional end-flow water shut-off system has a problem in that it takes considerable skill and attention in operating the devices, and the operation time is also relatively long.

As related prior arts, there is disclosed in Japanese Patent Application No. 10-1067247 (entitled "Valve disk for secondary end valve", filed on September 19, 2011) and 10-1023265 (entitled " An internal fluid shut-off head, registered on March 10, 2011).
