Description

A joint device of pipe which makes use of clip flange}

The present invention relates to a pipe fitting device using a clip flange, and in particular, a separate flange is firmly attached to the pipe with bolts, a packing is inserted around it, and the pipe is secured with a clip to securely connect the pipe while maintaining watertightness. The present invention relates to a pipe fitting apparatus using a clip flange which can be easily operated.

In general, pipes of various types and sizes are used, from water supply pipes for supplying water to sewerage where sewage flows.

These pipes are constructed by connecting several pipes to the place where tap water is supplied to the water supply and the sewage treatment terminal to the drainage water.

If the connection of the pipe is poor, the water supply wastes a lot of cost due to water leakage, and the sewage has a wastewater that is contaminated with groundwater due to leakage, and various methods for improving the actual watertightness have been studied.

Conventionally, the pipes are connected by using sockets or coupling pads to tightly and tightly connect the pipes.

The socket is simply expanded to a size such that a tube is inserted into one end, and a packing is built in the extended inside to be coupled to one end of the tube, and a tube to be connected thereto is inserted to have watertightness.

These socket joints are often subjected to high water pressure inside the tube, or when the single-colored color tube expands and contracts due to heat, the end of the tube inserted into the socket is often leaked.

In addition, the method of connecting a tube using a coupling pad includes a coupling pad wrapped around the tube to be connected to the tube surface by applying heat thereto, and inserting a coupling band having a bracket formed at the cut end into one tube. After inserting to match the center of the pipe to be connected, put the plate on the bracket and tighten the bolts to ensure that the pipe is connected tightly.

However, when the pipe is small, the defect rate is small, but when the tube is large, the construction error increases, so a lot of defect rate occurs. In particular, when the center of the pipe is misaligned, water leakage occurs frequently between the brackets of the coupling ring, and the coupling pad which functions as a packing may be torn by an external impact, and water leaks through the torn gap. Often happens.

If the leak is a water supply pipe will be wasted a huge cost due to the leakage of tap water, if the leakage of the sewage pipe will cause groundwater pollution.

The present invention was devised to solve such a conventional disadvantage, and its purpose is to install a flange by simple screw assembly at the connecting end of the pipe, and achieve a solid connection while maintaining good watertightness using the packing and the clip. To provide a pipe joint using a clip flange that can be.

In order to achieve the above object, the present invention, in tightly and tightly coupling the tube, adheres the flange in a state where the packing is in close contact with the end of the pipe to be connected, and then a plurality of screws are driven to the end of the tube to fix the flange. And an outer packing wrapping the flange around the flange of the tube to be connected, and fastening a clip around the outer packing.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in detail.

The pipe shown in the drawing is a double wall sewage pipe, which is formed by extruding a square pipe while winding it in a spiral and simultaneously crimping it. Of course, in addition to the double wall sewer pipe can be applied to various types of pipes.

As shown, the pipe joint structure of the present invention is designed to be connected by using the flanges 13a and 13b.

The pipes 10a and 10b and the flanges 13a and 13b are composed of separate bodies, and a circular packing 12a is provided between the ends of the pipes 10a and 10b and the flanges 13a and 13b. ) 12b is interposed.

In addition, a plurality of screw holes 11a are formed at regular intervals around the ends of the tubes 10a and 10b, and corresponding tubes 13a and 13b and the packing 12a and 12b are provided with a tube 10a. A plurality of screw holes 11b and 11c coinciding with the screw holes 11a of 10b are formed at regular intervals. A packing groove 15 is formed on one surface of the flanges 13a and 13b in contact with the packings 12a and 12b.

These parts are for forming the flanges (13a) (13b) to securely connect the pipes (10a) (10b) to be piped, the assembly is screw holes (11a) (11b) at the ends of the pipes (10a) (10b) ), The packings 12a and 12b are brought into close contact with each other, and then the flanges 13a and 13b are brought into close contact with each other to fasten the screws 16 through the screw holes 11a, 11b and 11c. When the screw 16 is fully tightened, the flanges 13a and 13b are firmly coupled to and integrated with the tubes 10a and 10b, and the packing is provided between the tubes 10a and 10b and the flanges 13a and 13b. Since (12a) and (12b) are interposed, it will have favorable watertightness. Of course, other pipes 10a and 10b to be connected will have the same flanges 13a and 13b. At this time, if the head of the screw screwed to the flange (13a) (13b) is projected to the outside space is formed between the flange (13a) (13b) to be connected to prevent the screw head as shown in Figure 2 It is comprised so that it may insert in the screw hole 11c of (13a) (13b). Then, the silicon 14 is filled and sealed in the screw hole 11c of the flanges 13a and 13b into which the screw heads are inserted.

In this state, the flanges 13a and 13b of the pipes 10a and 10b to be connected are brought into close contact with each other, and then the outer packing 17 is covered around the fasteners and then fastened with clips 20a and 20b.

The outer packing 17 is formed with a 'U'-shaped groove 18a so that the circumference of the flanges 13a and 13b can be covered on the inner surface of the outer packing 17 so that the circumference of the flanges 13a and 13b is external when the outer packing 17 is engaged. It is hermetically covered by the packing 17.

In addition, the clips 20a and 20b are separated into two bodies, and the outer packing 17 having the cross section covered with the flanges 13a and 13b on the inner side, such as the outer packing 17, is hermetically inserted. It has a structure having a 'U'-shaped groove 18b of a size that can be sized, and the engaging pieces 21a and 21b having screw holes 22a and 22b are formed at both ends to enable screwing.

Accordingly, when the outer packing 17 is attached to the outside of the clip (20a, 20b) and the clip (20a, 20b) in the upper and lower parts to the coupling pieces (21a, 21b) on both sides of the clip (20a, 20b) When the bolt 23 is fastened and fixed, it is firmly and tightly coupled.

At this time, if a separate packing is interposed between the corresponding flanges 13a and 13b, watertightness can be ensured even more.

As described above, the present invention installs a flange by simple screw assembly at the connecting end of the pipe, and closes it to the contact, and then attaches the outer packing to the outside and bolts the clip composed of two upper and lower bodies to connect the pipe. While maintaining good watertightness, it can have a firmly coupled state, and it is not only easy to manufacture and assemble, but also very convenient for maintenance and management.
