Description

Branch Branch Outlet Fitting System

The present invention relates to drilling a hole (inlet hole) in the side of the pipe to change the flow direction of the fluid without the use of the T pipe to attach the branch pipe to which the connection pipe.

More specifically, the branch pipe socket attachment device is generally a circular hole by using a cylindrical pipe. However, in the present invention, the upper branch pipe is a cylindrical tube type, and the lower branch pipe which is selected as the pipe inlet hole has a geometric cross-section (square, rectangle, ellipse and rectangle on both sides of the circle or ellipse,…, etc.), and the inlet hole lower branch pipe is formed in the pipe. It is characterized by drilling in the same cross section.

Therefore, inflow holes such as sewage, water, and gas pipes can be drilled with jig-saws, saws, cutters, etc., without expensive circular holes, and the lower branch pipes are wider than the upper branch pipes. If it is narrow and lengthwise, and the upper and lower branch pipe area is the same, but the maximum main pipe cross section and the lower branch pipe cross section are the same, it can be the same size as the main pipe.

Examples of conventional branch pipe socket attachment devices include Korea Utility Model Registration No. 0159690 and Korea Patent Registration No. 0531157. In this case, when installing a connection pipe on the side of the sewage main pipe, a circular hole (inlet hole) is drilled and a cylindrical pipe branch is connected thereto. The socket was attached.

Circular holes are required for drilling machines, and jig-saws, saws, cutters, etc. are difficult to use because the garden work is difficult and slanted or crushed after drilling.

In addition, when the inlet hole is drilled in the pipe, the size of the hole is limited for the safety of the pipe structure, so it was impossible to connect the same pipe with the main pipe as well as the large pipe.

Particularly, the inner washer with the wing pieces larger and curved than the inlet hole on the inner surface of the inlet was required to have a split inner washer.

In addition, when drilling a hole in the pipe with a perforator, the actual cutting portion is cut in the circumferential arc portion larger than the string, so the larger the connection pipe had a problem in the structural safety.

The present invention has no problem in the safety of the structure even if the size of the inlet hole connected to the inlet hole drilled on the side of the main pipe in order to solve the problems of the background art, as well as the heterogeneous T tube, as well as the positive T tube The branch branch socket attachment device using the same size pipe as the main pipe is the problem to be solved, and another problem is the central branch pipe structure to eliminate the bottleneck caused by the narrow width of the inlet hole drilled into the main pipe and lengthening in the longitudinal direction. Another problem is the development of a geometric inlet hole that does not use an expensive puncher when drilling an inlet hole, and the development of an inner washer that can be used in common even if it is deformed by earth pressure or has a different inner diameter. Development of fastening method for fastening or plugging the inner washer out of reach with branch pipe, developing packing for watertightness, and installing In addition for the divided saddle development and a low-pressure sewage pipes in a technical problem to be solved by the high pressure of the constant, the development latitude gas branch tube socket device.

The present invention is to solve the above technical problem by the fastening means for attaching them to the pipe inlet hole in the configuration of the branch pipe socket attachment device and the assembly means and watertight means of the lower branch pipe and the inner washer projecting pipe to solve the problems of the background art described above. It can be realized.

It has a geometric cross-sectional shape, and has a hooking portion formed on the inner surface, and forms a central branching pipe which eliminates a decrease in fluid flow between upper and lower branching pipes as necessary. An inner washer cut into at least one or two inner washers of curved wing pieces at the lower side of the lower branch pipe cross-sectional protrusion formed, and a projection pipe and an upper surface surrounding the lower branch pipe on the saddle having a curved surface. The upper branch pipe is formed with a protrusion formed by the upper branch and the lower branch pipe is moved up and down, the nut is fastened to the male screw, and the curved surface and the branch shaped in the cross-sectional shape of the lower branch pipe, the upper branch pipe male screw The upper part of the saddle protruding tube is pressed with a nut, and the fastening means is used. The packing is an assembly means that can not be pulled out by means of the above-mentioned packing is a watertight means of packing and other well-known packing watertight the upper end of the inner side of the wing piece (packing inner surface portion) integrally or pressurized to the lower side of the lower branch pipe. The problem can be realized. In this case, when the cross section of the lower branch pipe is rectangular, the cylindrical upper branch pipe diameter and the square lower branch pipe width and length may be the same, and when the upper branch pipe cross section and the lower branch pipe cross section are equal, It is preferable to form a central branch pipe integrally between the upper and lower branch pipes so that the lower branch pipe width and length can be reduced, thereby eliminating fluid flow reduction.

In addition, as a fastening means, it is also possible to form a protrusion frame outwardly above the upper branch pipe, form an outward protrusion frame on the saddle protrusion, and install a plurality of turn-buckles between the protrusion frames.
