[0001] The present invention relates to a sealing device for a tubular sealing device,

The present invention relates to a sealing device for a sanitary pipe for a continuous water shut-off method, and more particularly, to a sealing device for a sanitary pipe for a continuous water shut-off process, comprising a stopper means provided on an upper portion of a sandwich valve for opening / closing a passage of a sanitary pipe, The bolt fastening process is performed inside the sandwich valve, so that the stopper can be fastened in the state of the sandwich valve, and the sandwich valve is prevented from being leaked until the stopper is tightly fitted to the flange, The present invention relates to a sealing device for a sanitary pipe.

Generally, a fluid shut-off method for temporarily shutting off a pipeline at an arbitrary position in order to repair a pipeline through which a fluid flows, such as a water pipe, a sewer pipe, or a heat pipe, includes a pipe called an end water blocking method or a line- Blocking method is used. This is accomplished by using a fluid cut-off device having a blocking head of various shapes and structures such as a pivot-type blocking head inserted into a pipe to block the fluid, a folding blocking head, It is possible to maintain the piping and the like without affecting the fluid supply state of the entire pipeline.

A plugging device is used to close the fitting device installed in the piping after maintenance of the piping is completed. The prior art that is used for plugging to close the opening of the fitting device is disclosed in Japanese Patent Application No. 10-2002-7005623 entitled 'A member for removably closing the cylindrical opening' and Application No. 10-2010-0112036 ' Fitting ".

The conventional plugging device has a complicated structure of the plug itself coupled to the fitting device and it is very difficult to stably insert the plug when the plug is coupled to the fitting device. The reason for this is that when the plug is attached to the plugging device and the plug is installed in the static tube of the fitting device, it is impossible to visually confirm the inserting process and the coupling state of the plug, There is a disadvantage that the structure is clogged because the structure for pushing is necessary.

Further, after the plug is mounted, there is a problem that an open upper portion of the fitting device is fixed with a separate finishing plate to make an extension part (an engagement plate) of the plug.

SUMMARY OF THE INVENTION The present invention has been developed in view of the above problems, and it is an object of the present invention to provide a stopper fixing means on an upper portion of a sandwich valve for opening and closing a passage of a static tubular member and fastening the stopper to a flange at an upper end of the passage, And the clamping process is performed inside the sandwich valve to enable the closure of the closure in the presence of the sandwich valve and to prevent the sandwich valve from being leaked until the closure is tightened with the sandwich valve being in close contact with the flange. Thereby providing a sealing device.

The present invention provides a sanitary napkin for a sanitary napkin which comprises a sanitary pipe having a cylindrical body coupled to an outer circumferential surface of a pipe and is coupled to the sanitary pipe so that an outer circumferential surface of a flange provided at an upper end of a passage of the sanitary pipe and a lower end inner circumferential surface of a valve passage are closely contacted, And a stopper provided at an upper end of the sandwich valve and surrounding the upper end of the valve passage, the stopper being provided with a pressing plate for pressing the stopper so that the stopper is in close contact with the flange, A sealing apparatus for a sanitary pipe for water-blocking method, the bolt being fitted in a bolt through-hole of the plug so as to be placed inside the plug fixing means; The cap fastening means is provided with an outer tube surrounding the plug and the press plate. The outer tube has a bolt fastener connected to the bolt. The bolt fastener has an upper end protruded out of the outer tube, So that it can be fastened.

According to the present invention, since the sandwich valve is not directly attached to the flange surrounding the open passage of the sanitary pipe, the flange is exposed to the valve passage of the sandwich valve. That is, when the sandwich valve is fixed to the sanitary pipe, both side surfaces of the sandwich valve and the body of the sanitary pipe are fixed by connecting the turnbuckle so that the flange of the sanitary pipe is not covered by the sandwich valve.

Therefore, the plug can be bolted to the exposed flange of the sanitary tube while the sandwich valve is fixed to the sanitary pipe. Conventionally, when the sandwich valve is directly bolted to the flange of the sanitary pipe, the flange is blocked. Therefore, a separate plug (a kind of temporary stopper) should be installed inside the passage of the sewer pipe to temporarily block the passage, and then the sandwich valve should be removed to expose the flange to the outside. There is a problem that the stopper is inserted into the flange, and the end of the stopper is sealed, so that the stopper is double-inserted and the operation is troublesome.

The present invention is characterized in that the flange of the sanitary pipe is kept exposed to the valve passage of the sandwich valve in a state where the sandwich valve is coupled to the sanitary pipe, so that the sandwich valve can be fastened to the flange of the sanitary pipe . A stopper securing means is provided above the sandwich valve to allow the stopper to be fastened within the sandwich valve.
Further, since the valve plate of the sandwich valve reciprocates in a state of being in close contact with the surface of the flange, leakage of water can be blocked until the plug is fastened to the flange.
