[0001] ELECTRIC MELTING TYPE SOCKET FOR CONNECTING GAS PIPE [0002]

The present invention relates to an electrofusion joint for gas pipes, and more particularly, it is possible to more conveniently install the electrofusion joint pipe for maintaining the air tightness coupled to the connection portion of the gas pipe, it can be confirmed that it is completely installed. The present invention relates to an electric fusion joint pipe for gas pipe, which can be separately fused on both sides.

Because the gas pipe passes through high-pressure gas, there is a great risk of fire or explosion if it leaks.

In order to prevent this risk, an electric fusion splicing tube, which is fused and fixed with electricity, is used to connect the gas pipe and the gas pipe.

The conventional fusion splicing pipe is formed to couple the gas pipe 17 and the gas pipe 17 on both sides as shown in Figure 6, the coil 9 is wound on the inner wall, both ends of the coil (9) Is formed to be connected to the power supply terminals 4, 4 'formed in the protruding sockets 2, 2'.

Conventional electric fusion splicing pipes have been disclosed in Korean Utility Model Registration Utility Registration No. 0312779 and Published Utility Model Application No. 87-14828.

However, the conventional electric fusion splicing pipe has the following problems.

(1) Since it is necessary to weld the gas pipes at the same time while inserting the gas pipes from both sides at the same time, it is difficult to install them step by step.

(2) It is difficult to confirm whether the gas pipe is adhered because it is difficult to understand the degree of fusion.

(3) It is difficult to estimate the appropriate time required for welding, so that the installer must continue to watch until the welder is completely welded.

The present invention is a general electro-fusion joint pipe,

And a first and second coils installed on the inner wall of the body on both sides of the protrusion, wherein the first and second coils are disposed on both sides of the body, The first and second sockets are formed with electrode terminals for connecting the ends of the first and second coils to each other. The first and second indicators are formed to be spaced apart from the first and second sockets .

According to the electrofusion joint pipe for the gas pipe of the present invention the following effects occur.

(1) The two gas pipes to be installed can be welded together without welding at the same time.

(2) It is easy to check the degree of fusion due to the indicator.

(3) Since a resistance terminal is formed which can cut off the power supply when a suitable resistance necessary for raising the temperature of the coil is set and the temperature rises sufficiently, it is not necessary to observe the fusing process of the operator.

The present invention is a general electrofusion joint pipe (1), the body 100 is formed so that the gas pipe 17 can be inserted, the center of the body 100, the end of each gas pipe 17 Protruding holes 102 are formed, and first and second coils 200 and 300 embedded in the inner wall of the body 100 are formed on both sides of the protruding hole 102, respectively. First and second sockets 220 and 320 protruding therein are formed in the electrode terminals 210 and 310 connecting the ends of the 200 and 300, and the first and second indicators 240 and 340 are spaced apart from the first and second sockets 220 and 320. Is formed.

The gas pipe 17 is formed of a synthetic resin material, the end of which is inserted into the fitting pipe (1).

Depending on the angle of intersection of the ends of the gas pipe 17, the shape of the joint pipe 1 may be formed horizontally as shown in FIG. 1 or perpendicularly as shown in FIG. 5, and may be formed at various angles.

When the joint pipe 1 is not formed horizontally but bent at a predetermined angle, the protrusion 102 is not formed and a step 104 is formed as shown in FIG.

The first and second coils 200 and 300 are formed in the same manner, and the first coil 200 and the second coil 300 are separated and operated separately.

The first coil 200 and the first coil 200 are connected to the electrode terminal 210 formed on the first socket 220.

The first sockets 220 are formed as a pair, and the electrode terminals 210 are protruded one by one.

One of the first sockets 220 is formed with a resistance terminal 250 spaced apart from the electrode terminal 210. When the resistance of the first sockets 220 is increased by a predetermined resistance or more So that the power supplied from the electrode terminal 210 can be cut off.

The first indicator 240 is formed to be spaced apart from the first socket 220, the indicator 240 is deeply dug a donut-shaped groove in the body 100, the first indicator bar 242 is formed in the center do.

The first indicator 240 may be formed in the center of the first socket 22 formed as a pair.

The second coil 300, the electrode terminal 310, the second socket 320, the second indicator 340, the second indication bar 342 and the resistance terminal 350 are all connected to the first coil 200, The first indicator 240, the first indication bar 242, and the resistance terminal 250. The first electrode 220, the first indicator 240, the first indication bar 242,

Hereinafter, a description will be given of the operation and use method of the electrofusion joint pipe for gas pipe formed in a preferred embodiment of the present invention.

The gas pipe 17 is inserted into the first coil 200 or the second coil 200 by pushing the gas pipe 17 into the body 100 of the joint pipe 1. [ Another gas pipe 17 to be connected can be simultaneously inserted and operated.

If the gas pipe 17 is inserted into a portion where the first coil 200 is formed, two power lines of the first socket 220 are connected.

When power is applied by connecting the power line as described above, power is applied through the electrode terminal 210, and heat is generated in the first coil 200 to melt the surface of the gas pipe 17.

When the power is supplied and the inner wall of the body 100 is fused to the surface of the gas pipe 17, the resistance terminal 250 cuts off the power.

When the power is supplied and the inner wall of the body 100 and the surface of the gas pipe 17 are melted and fused, the indication bar 242 is positioned at the weakened part of the wall of the body 100, The degree of fusion can be confirmed according to the degree to which it has been raised.

When the two gas pipes 17 are to be connected at the same time, the first and second coils 200 and 300 must be simultaneously operated. In this case, one power line is connected to one socket 200 of the first socket 200 And the remaining power lines are plugged into the power terminal 310 formed in one second socket 300 of the second socket 300 and then the remaining two sockets are connected to each other to be operated simultaneously have.

According to the electrofusion joint for gas pipes of the present invention, two gas pipes to be installed can be welded together at the same time without being fused at the same time. It is easy to check and sets the proper resistance necessary for the temperature rise of the coil, and if the temperature rise is enough, a resistance terminal is formed to cut off the power. have.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the scope of the invention as defined by the appended claims.
