Description

Apparatus for union of pipe arrangement}

The present invention relates to a binding device, and more particularly, to a pipe connecting a pipe forming a pipe, without a welding work or a screw work, etc., the bracket is provided with a sealing packing to maintain the airtightness of the pipe to be connected and The present invention relates to a piping binding device that can be connected to a pipe more easily by clamping the pipe to a sealing packing.

Normal pipes are mainly used for transporting fluids (liquid and liquid) and powders, and are also used for the protection of electric wires and cables when wiring in the ground or indoors. The passage of the fluid constituted by the pipe is referred to as a pipe line, and the pipe is reasonably installed in consideration of the flow rate, physical property value, frictional resistance, and the like of the fluid.

Such pipes are generally manufactured in standardized sizes, and in the case of pipes extending over a certain length, the standardized pipes may be formed using predetermined connectors, for example, elbows, tees, and flanges. The coupling method is a permanent coupling method and a decomposable coupling method.

Here, there are welding joints and solder joints in the permanent coupling method, and fluids do not leak out, and maintenance costs and equipment costs are saved, but there are a lot of problems when trying to change the pipe due to breakage of pipes due to the inability to disassemble. In addition, the decomposable coupling method is a flange joint which uses a screw coupling, a voltage flange, a rivet flange, a welding flange, a solder flange, etc. to make a flange and fastens with a bolt, and a pipe end. Screw joints are used, which are used for digging screws, elbows, T branches, crosses, sockets, bands, unions, and nipples. It can be used in, but takes a lot of time during construction, there is a problem that requires a skilled worker.

As described above, the binding method of the pipe according to the prior art has a problem of inferior in economic efficiency because it requires a work by a skilled worker because the installation cost increases due to the high cost and precision is required for the work, and it takes a lot of working time. There is a problem in that the assembly process is complicated by using a lot of electricity and using a lot of parts, and there is also a problem of wasting a lot of manpower and time because the risk of water leakage is high and the work must be reconstructed in the same manner as above.

The present invention has been devised to solve the above problems, it is possible to increase the economic effect by simplifying the work process for the connection of the pipe during piping, avoiding the high cost and a lot of manpower and time, It is an object of the present invention to significantly reduce the occurrence of water leakage, and to provide a pipe binding device that can be easily disassembled and combined even if the water leakage occurs.
