Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connecting device for connecting a branch pipe,

The present invention relates to a connecting device for connecting a branch pipe, and more particularly, to a connecting device for connecting a branch pipe, and more particularly to a connecting device for connecting a branch pipe to a branch pipe, And more particularly to a connecting device for connecting a branch pipe to prevent disengagement of a bonded state of a bronze connection socket welded to the main body part due to excessive screwing of the pipe.

In general, a branch pipe is a branch pipe used to connect to a main pipe for transferring a part of a fluid flowing through the main pipe to another place.

These branch pipes are connected to the main pipe and widely used in various fields in order to supply water for heating piping of houses, hydroponic cultivation of crops and a wide area of crops.

The main pipe and branch pipe branching from the main pipe are made of metal or synthetic resin, and those made of synthetic resin that requires easy installation and low construction cost are widely used.

Meanwhile, when the branch pipe is connected to one side of the main pipe, the branch pipe is connected to the main pipe by fixing the branch pipe by welding or heat fusion so as to communicate with the branch pipe formed at the side of the main pipe.

However, such a conventional branch pipe connection structure has a problem that the construction work is very troublesome, the work time is long, and the working efficiency is very low.

In addition, the conventional branch pipe connection structure has a problem that the branch pipe is separated from the main pipe or leakage between the branch pipe and the main pipe is serious because the connection strength and the sealability between the branch pipe and the main pipe are very weak.

Korean Utility Model No. 20-2007-0000842 for solving the above-mentioned problems discloses a technique relating to a joint capable of performing a quick and easy branching operation by using a pipe branch joint.

However, in the conventional branching joint, during the process of coupling the valve to the joint body, one side of the connection tube fused to the joint body due to the excessive rotation assembly of the valve is broken and revolved, There is a problem that leakage occurs frequently.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide an air conditioner, which is constructed such that a through hole formed in a main pipe is communicated with an inner side of a communication hole of a main body part by a center tube removably mounted inside the main body part, And to provide a connecting device for connecting a branch pipe.

In addition, in the process of connecting the branch pipe, it is possible to prevent the fusion bonding state of the bronze connection socket welded to the main body part from being released due to the excessive screw connection of the branch pipe, And a valve member coupled to a tip end of the branch pipe is screwed into the bronze connection socket so as to form a protruding tab and an engaging piece on the outer periphery of the fitting hole which is fusedly coupled to the inside of the communication hole of the main body portion, It is possible to prevent the release of the fusion bonding state of the bronze connection socket due to the excessive rotation of the branch pipe during the connection.
