The present invention connects the branch pipe (branch pipe) to the side of the main pipe to branch the fluid transferred to the main pipe to the branch pipe (branch pipe) or to supply the fluid of the branch pipe (branch pipe) to the main pipe It relates to a branch pipe connection connector for.

In more detail, the connection body assembly is installed by inserting the connection body assembly from the inside of the main tube to the connection hole (connecting hole) drilled on the side of the main tube and protrudes to the outside of the connecting hole (connecting hole). The body body of the sealing support ring is fitted, the body body of the connection body assembly in which the sealing support ring is fitted by screwing the binding washer assembly, and fixed (mounted) on the outer surface of the main tube of the binding washer assembly In the state where the branch pipe is loaded in the engine room, the top cover of the binding washer assembly is mounted by bolts / nuts, and the sealed binding ring is coupled between the coupling washer assembly and the inside of the binding cover plate, which are combined as described above. It is an object of the present invention to provide a branch connection connection for sealing a detention branch.

In general, pipes (PIPE: pipes) used to transfer fluids or gases are used in various fields, such as various industrial facilities, water and sewage facilities, and various pressure piping facilities. Depending on the material, metal or non-metal (synthetic resin) materials are used. Molding is manufactured.

A pipe (pipe) installed for various purposes in various industrial sites distributes the fluid or gas transferred from the main pipe (pipe) to branch pipes (branch pipes) or branches (branch pipes) when transferring fluids or gases. In order to collect the fluid or gas supplied from the main pipe into the main pipe (branch pipe) is connected (connected) to the main pipe.

Conventional techniques related to branching of pipes as described above include branch branch socket attachment devices, branch pipe connection clamps, coupling holes (connecting members) of main sewage pipes and branch sewer pipes, branch pipes for pipes, and water-tight mechanisms for PVC DC. Etc. are known.

In particular, the conventional technology related to the branch pipe connector according to the present invention, the branch pipe socket attaching device of Korea Utility Model Registration No. 20-159689 and the branch pipe socket attaching device and Registration Patent No. 20-307725 of Registration Utility Model No. 20-307725 10-696448 elastic hinged double-walled pipe branch outlet, the branch pipe connector of the Patent No. 10-772118 and the branch pipe connector of the Patent No. 10-772118 and the like are known.

Each branch pipe socket attaching device of the Utility Model Registration No. 20-159689 and the Registration Utility Model No. 20-307725 is fitted with an inner washer with a wing piece formed at the lower edge of the vertical pipe in the inlet hole drilled into the main pipe. However, the vertical tube is coupled to the outside through the inlet hole, and the inner tube is projected to the outside of the main pipe through the inlet hole, and the cover plate (lower surface) is integrally formed at the lower periphery of the connecting tube (protrusion frame). Inserting and connecting the branch pipe socket, and in this state of coupling, the vertical pipe of the inner washer and the connecting pipe (protrusion) of the branch pipe socket are bolted together to be integrated, and the connection of the branch pipe socket connected as described above. It is to install (insert) the end of the connecting pipe (branch pipe) to the pipe (protrusion frame).

However, they are inferior in watertightness between the branch pipe socket and the main pipe, and cannot be maintained, and the work is performed quickly and easily because the inner washer (vertical pipe) and the branch pipe socket (connection pipe) are connected with bolts. The work efficiency of installing a connector (branch) is inadequate.

In addition, since the inner washer with the wing piece formed on the lower periphery of the vertical pipe is divided by the hinge (hinge), the coupling force and the sealing force are reduced when it is coupled to the inlet hole drilled in the main pipe, so the device can reinforce it. (Means) must be added inevitably, and the composition and workability become complicated, and the work efficiency is reduced.

In addition, since the inner washer and the branch pipe socket are combined to take a plurality of bolts, there is a need to use a separate bolt tightening tool, and the connection surface between the inner washer and the branch pipe socket is narrow so that the pressing force (sealing force) is narrow. When the bolt is tightened with excessive force, the male thread of the bolt is worn or damaged by the inner thread of the inner washer and the tightening force is reduced.

In addition, the elastic hinged double wall pipe branch of Patent No. 10-696448, in the elastic hinged double wall pipe branch that is mounted in the drilled hole of the main pipe, the upper portion corresponding to the branch pipe to be connected to the drilled hole of the main pipe. Branch sleeves having internal diameters of different sizes and having a threaded portion at the bottom thereof; Coupling holes of an arcuate skirt in close contact with the perforated holes of the main pipe, and saddles having hollow circular protrusions formed around the coupling holes; On the inner periphery of the divided body to form another threaded portion having a shape of either male or female threads on the inner circumference of the bisected body so as to correspond to the screw shape of the threaded portion of the branch sleeve inside the coupling hole. An elevator having a bisected protrusion border; Forming a 'U' cross-sectional shape, such as the inner space in the lower portion is coupled to the protruding edge, the packing portion coupled to surround a portion of the inner circumference of the elevator.

This inserts the elevator combined with the packing part into the hole (installation hole) inside the main pipe so that the elevator body is exposed to the outside, and the saddle is inserted into the body exposed to the outside of the main pipe through the hole (installation hole). In assembling by screwing the threaded portion of the connection portion of the branch sleeve and the body of the elevator equally, it is to be installed by inserting the branch pipe into the branch sleeve.

However, this is inconvenient to maneuver because it is necessary to screw the branch sleeve directly to the elevator by lifting the branch sleeve or release the coupling state, and the compression and sealing force is weak because the branch sleeve is directly screwed into the elevator, the packing part coupled to the lower part of the elevator Since the sealing force is lowered by the main pipe, and the branch sleeve is simply inserted into the branch sleeve, the sealing force is decreased so that water leakage may occur. Therefore, a separate sealing means should be taken to prevent this.

In addition, each branch pipe connector of the registered patent Nos. 10-772118 and 10-772118, the branch pipe connector connecting the main pipe and the branch pipe, the body body made of a rigid body as a whole and cylindrical from the top to the bottom The lower part protrudes outward from the center and has the same outer diameter as the diameter of the branch hole formed in the upper main body, and is composed of a saddle-shaped main wing, but the diameter of the outer circumference of the upper main body is made smaller than the branch hole formed in the main building. A screw part is formed in the body, and a main body fitting groove is formed in which the upper packing is fitted along the circumference of the upper surface. A main body formed with a seating portion on which the end of the branch pipe is mounted; The upper part has a saddle shape while having an overall cylindrical contact portion, the inner circumferential surface of which is in contact with the outer periphery of the main body, and a portion of the outer periphery, which is configured to be in close contact with the circumference of the branch hole. packing; Cylindrical support body, the support wings protrude outwardly in the lower portion of the upper support body and formed in a saddle shape in order to prevent the main body from swinging in contact with the outer periphery of the main body, at regular intervals along the outer periphery of the upper support body A support washer formed of a triangular support piece which extends to the upper surface of the upper support wing, and a sliding washer formed to protrude inward toward the center with a predetermined volume on the inner circumferential surface of the upper support body so as to fit into the slide groove of the main body; A lower nut as a lower fastening means inserted into a threaded portion formed at an outer circumference of the screw, coupled to the upper surface of the upper support washer, and having a fastening groove in a longitudinal direction at regular intervals on the outer circumference; As a watertight means of the part in contact with the branch pipe is generally formed in a band shape, the outer surface of the upper portion is an inclined portion of which the outer diameter increases as the bottom, the inner portion of the upper portion protrudes downward along the inner circumferential surface, the lower body fitting groove An upper packing as an upper watertight means formed in a fitting protrusion which can be fitted to the inner circumferential surface so as to closely surround the outer circumferential surface of the branch pipe; And an upper fastening means which allows the upper packing to be in close contact with the outer circumference of the branch pipe, is screwed into the thread formed on the outer circumference of the main body, and is fastened in the longitudinal direction at regular intervals on the outer circumference. The upper nut is formed inside the pressing portion of the shape corresponding to the upper packing inclination portion.

However, this is because the main wing formed in the downward inclined surface on the lower end of the main body to support the lower end of the contact portion (cylindrical) of the lower packing, the contact portion formed of a solid material when the main body body is strongly coupled (screwed) The lower part of the contact part (cylindrical) of the lower packing made of soft, and the contact part is not able to strongly detain the edge of the hole (installation hole) formed in the main pipe, and because of this, the lower nut can not be screwed strongly so that it is somewhat loose Since it must be combined, the sealing ability is weakened.

In addition, when the upper packing is installed on the upper end of the main body, the lower protrusion of the packing should be simply inserted into the groove formed on the upper surface of the main body so that the upper packing cannot be easily installed, and the coupling force (binding force) of the recess and the lower protrusion is There is a fear that the upper packing is easily separated by weak.

In addition, since the upper nut and the lower nut are formed with a concave fastening groove formed in the inner surface instead of a fastening protrusion projecting to the outside, the upper nut and the lower nut cannot be easily and reliably gripped, and the upper nut and the lower nut are When rotating, slip phenomenon occurs and it is impossible to smoothly rotate (fasten and release), and thus it is impossible to strongly fasten the upper nut and the lower nut.

The present invention connects the branch pipe (branch pipe) to the side of the main pipe to branch the fluid transferred to the main pipe to the branch pipe (branch pipe) or to supply the fluid of the branch pipe (branch pipe) to the main pipe It is intended to provide a branch connection connector for the same.
