Description

Plug {PLUG}

More particularly, the present invention relates to a plug, and more particularly, it relates to a plug capable of improving the closing efficiency of the fitting of the fitting provided in the piping by the rotation of the plug, As shown in Fig.

Generally, a water pipe is composed of a main pipe of a large diameter for transferring large-capacity constants over a long distance, and a branch pipe for branching at a main pipe and used as a relatively short distance feeder for supplying water to buildings such as homes and offices. In this way, a valve is installed in the branched body so that the interception of the water can be performed, so that the operation can be easily performed by replacing the old or damaged water pipe or replacing the valve.

This method has a problem in that the number of valves installed around the replacement point is closed after the valve is closed to shorten the constant supplied to the water pipe or valve of the replacement point.

In addition, if the water supply system is used, it will cause inconvenience and loss to each family and various industrial facilities, and will cause inconvenience to the public. In case of emergency management, There has been a problem that the corrosion of the piping is intensified and it is difficult to deal with manual piping.

In order to solve this problem, a fluid-cutting method is a method called a step-end blocking method or a line-stopping method, which is a pivot type blocking head inserted into a pipe to block the fluid, a folding type blocking head, , And a part of a variety of pipelines such as a water pipe, a heat pipe, a gas pipeline, and a gas pipe is arbitrarily blocked by using a fluid blocking device having a blocking head of various shapes and structures, It is a method to maintain the piping.

The pivoting blocking head is also called a "pail head" as a blocking head in which the blocking head itself is formed in a disc shape. The pivot-type blocking head has a disc shape so that the blocking head can be brought into close contact with the inner surface of the pipe to be blocked. Therefore, the insertion port formed for inserting the blocking head into the pipe must be formed to have the same size as the diameter of the pipe.

The folding type blocking head has a problem in that, in the case of the pivot type blocking head, the insertion port must be formed to have the same size as the diameter of the piping, and the blocking head can be folded so that the insertion port can be formed to be smaller than the diameter of the piping .

In order to solve the problem that the insertion port needs to be formed to have the same size as the diameter of the pipe in the case of the conventional pivot type blocking head like the folding type blocking head, Can be formed to be smaller than the diameter of the pipe.
