Description

DISC TYPE HEAD WITHOUT STOPPING WATER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a continuous-discontinuous disc-type head applied to a fluid shut-off device in a continuous-end water shut-off method, and more particularly to a continuous-discontinuous disc-type head having improved rigidity and water tightness .

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, .

As an example of such an end-tapped water shut-off method, "Tube laying method using fluid circuit breaker for piping" is filed as a patent application (Application No. 10-2007-0036571), and a valve body is installed in a piping, A mounting step of installing a fluid circuit breaker for a piping by using a coupling part formed on a lower body of a valve body installed in the piping in the preparing step and placing the blocking device in the piping after the installing step; A step of supplying a working fluid after the step of seating to cut off the fluid by operating a cutoff device, a reinforcing work step of installing or repairing the piping in a state in which the fluid is blocked by the cutting step, And a sealing step of sealing the perforated hole is disclosed.

More specifically, referring to FIG. 3, a process of replacing the pipe by using the end water blocking method will be described. In the pipe line for the purpose of the work, a regular pipe called a fitting is installed (S1).

In the case of a steel pipe, the bobbin portion is welded directly to the pipe.

Thereafter, a sandwich valve is installed at the branched portion on the upper side of the bobbin (S2). The sandwich valve is structured and operated in the same manner as a conventional gate valve, and opens and closes the opening portion of the sliding pot according to opening and closing operations.

Then, a boring device is coupled to the sandwich valve to make a hole in the pipe (S3). Such an operation is to form a hole for inserting the shut-off head of the fluid shut-off device into the channel, and it is perforated as necessary according to the size of the shut-off head of the fluid shut-off device.

When the drilling is completed, the drilling device coupled to the sandwich valve is removed, and a fluid shutoff device is installed (S4). Thereafter, the fluid shutoff device for the pipeline is operated to shut off the fluid (S5). When the fluid is blocked and the work section is secured, a pipe operation such as pipe replacement, valve replacement, new valve installation, pipe connection work, and the like is performed in the work section (S6).

Then, a dynamic pressure operation is performed in which the pressure side of the fluid cut-off device is closed by the fluid cut-off device and the pressure of the side without the hydraulic pressure is matched (S7).

When the dynamic pressure is established, the fluid shutoff device is removed and a plugging operation is performed (S8). Thereafter, the sandwich valve is removed, and the blind cover is joined to the pottery pipe where the plugging operation is performed (S9).

However, the conventional fluid cut-off device installed in the pipe through the perforations formed in the pipe can not easily break the pressure of the fluid flowing in the pipe, or is easily attached to the inside of the pipe, .
