The present invention comprises: a tee pipe main body provided to the outer circumference of a main pipe; a connection pipe flange provided to one end of the tee pipe main body to enable the tee pipe main body to be connected to a connection pipe having a different diameter from a tee pipe; and a sealing flange connected to the other end of the tee pipe main body.

Description

THE PIPE ASSEMBLY WITHOUT STOPPING WATER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an end-stopping and shut-off valve assembly applied to a continuous water shut-off method such as a water pipe, a district heating pipe, an oil pipeline and a gas pipe. More particularly, And more particularly, to an assembly for intermittent water shut-off valves that can be easily connected to pipes of different types.

In general, the fluid shutoff device applied to the end water shutoff method is widely used as a means for shutting down some sections of various pipelines such as water pipes, heat pipes of district heating, oil pipelines and gas pipes, The blocking means is inserted into the conduit to block the flow of fluid.

Referring to FIG. 1, an example of using the fluid shutoff device will be described. As shown in FIG. 1 (a), in the conventional method of replacing a pipeline such as a water supply pipe, And the wiping valve 2, it is possible to divide the replacement work section only. Therefore, as shown in FIG. 1 (b), there is a problem that the entire section is divided except the replacement work section.

Generally, since the interval of the drain valves is 1 km to 3 km, there is a problem that the number of inhabitants who suffer from the inconvenience of life and the living business are damaged due to the occurrence of a large number of singular areas. In addition, when the wastewater performance is poor or the operation is poor due to aging of the wastewater valve 1 or the wastewater valve 2, there is a problem that the number of the wastewater area is greatly enlarged.

In addition, in the case of the single step method, since the water in the pipe must be drained and attached, the operation time is considerably long, which leads to an increase in the number of hours.

As shown in FIG. 2, a blockage method for solving such a problem is provided with a fluid cutoff device acting as a temporary drain valve on both sides for the degree of only a replacement work section to secure a work section.

That is, the fluid shutoff device acts as a wiping valve, so that only the replacement work section is a step, as shown in FIG. 2, and the other areas are not affected.

Because of this characteristic, the end block waterproofing method has only a minimum number of sections, and it is possible to work irrespective of the existing pre-installed water valve, thereby reducing the replacement work time of the pipe, .

FIG. 3 is a process diagram for connecting a branch pipe to a pipe main pipe by using a conventional end-flow cutoff pipe for installing a fluid cut-off device in the case of performing the end water blocking method. As shown in FIG. 3 (a) 2) around the outer circumference of the tube. 3 (b), the gate valve 20 is mounted to the branching portion 12 of the primary end cap 12 with bolts 21 and a nut.

The gate valve 20 includes a valve body 23 having an opening 22 communicating vertically with the branching portion 22 and a valve body 23 connected to the valve body 23 to open and close the opening 22 of the valve body 23. A valve cap 25 covering the valve body 23 and an operation part 26 for actuating the valve body 24 to operate the valve.

3 (c), the perforation device 30 is mounted on the gate valve 20 in a state in which the gate valve 20 is mounted as described above.

3 (d), the cutter 32 of the punching device 30 is lowered to form the perforations 4 in the pipe main pipe 2. 3 (e), the cutter 32 of the punching device 30 is raised, and then the operating portion 26 of the gate valve 20 is closed so that the valve body 24 The opening 22 of the gate valve 20 is sealed.

Then, the perforator 30 is separated from the gate valve 20, and the branch pipe 40 is mounted to the gate valve 20 with bolts and nuts as shown in FIG. 3 (f).

When the gate valve 20 is finally opened, the valve body 24 opens the opening 22 of the gate valve 20 and the fluid in the pipe main pipe 2 flows through the perforations 4 and 5 Passes through the inside of the base portion 22 and the opening portion 22 of the gate valve 20 in order and flows out into the branch pipe 40.

However, according to the conventional art, since the low sealing force between the main pipe and the main pipe causes leakage of the fluid flowing out from the main pipe to the outside of the pipe, the time for replacing the pipe There is a problem in that it can not be easily connected when the diameters of the main pipe and the main pipe are different from each other.
