Description

Expansion Coupling Pipe {A Expansion Coupling Pipe}

The present invention is a new joint that can be easily and easily connected by using a new joint pipe when repairing the pipe damage area of the underground and the pipe after the underground pipe is buried when fusion construction of the pipe composed of synthetic resin pipe It relates to a pipe, and more specifically, both ends of the underground buried pipe through the coupling means by constituting the expansion pipe formed by fusion connection or integral injection joints formed at the end of both sides of the pipe of the predetermined length By connecting, preventing the separation of the pipeline due to the expansion and contraction of the synthetic resin material pipe, and relates to the expansion joint pipe to facilitate the operation and repair of underground buried pipe.

In general, a pipe made of a metal material is used for a water pipe such as a pipe for transferring a fluid (liquid or gas), and such a pipe is buried underground.

When embedding the above-mentioned metal pipe in the basement, it is not possible to change the direction of pipe movement through the free path, and it becomes very difficult to transport and install the pipe, and the length of the pipe is relatively short (about 30 to 40 cm). The pipes are connected to metal pipes by joints.

However, the metal pipes buried underground as described above, due to the narrow working space of the underground, when the connection through the metal connecting pipe, the metal pipes are inflexible, so that the length of the short to produce, As a result, the connection pipe is used for emergency repair of the pipe, not for expansion purposes, and the pipe may be separated or leaked, and it is impossible to use it for the use of synthetic resin pipe with a large expansion coefficient such as synthetic resin. There were many problems.

The present invention has been made in order to improve the various problems as described above, the purpose is to fusion-connect the joint pipe formed with a stepped portion at both ends of the synthetic resin underground buried pipe, or the expansion joint formed by a single injection molded synthetic resin It is constructed to be relatively long in order to cope with the expansion amount in consideration of the expansion coefficient, so that it is connected to both ends of the underground buried pipe through the coupling means, thereby preventing the separation of the pipeline due to the expansion and contraction of the synthetic resin pipe, and the work of the underground buried pipe And to provide an expansion joint that can be easily repaired.

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

1 is an exploded perspective view of the expansion joint according to the present invention, Figures 2 and 3 is a state diagram showing the coupling state and the coupling state of the pipe through the expansion joint of the present invention, the synthetic resin connector 110 Both ends of the) is provided with an inclined end portion 120 is inclined at an angle to the end of the connecting pipe 110 through the fusion bead 130 is fusion-bonded or formed of an integral injection tube 140 ) Is installed, and the pipe fitting groove 150 inclined at an angle is formed inside the expansion joint pipe 140, and the pipe fitting groove 150 inclined inside the expansion joint pipe 140 is formed on both sides of the pipe ( One end of the 230 is installed to be inserted and fixed respectively.

In addition, at the periphery of the outer inclined end portion 120 of the expansion joint pipe 140, the metal ring for binding reinforcement 160 is installed respectively, and the pressure ring 200 installed on the outer circumferential surface of the both side pipe 230 is the pipe ( The locking jaw 180 is formed at the end via the sealing packing 170 installed on the 230. The coupling bolt 190 and the nut 210 form the metal ring 160 for strengthening the binding of the expansion joint 140. And the locking step 180 of the coupling bolt is coupled to be fixed.

At this time, the binding reinforcing metal ring 160 located on the outer circumferential surface of the inclined end portion 120 of the expansion joint 140 is inclined portion 161 is formed inward to be fixed in close contact with the inclined end portion 120, or Stepped portion 220 of the right angle is formed at the end of the expansion joint 140 is made of a configuration in which the flat ring 162 of the disc is installed.

Referring to the operation and effects of the present invention made of such a configuration as follows.

As shown in Figures 1 to 4, both ends of the connection pipe 110 made of a synthetic resin material by the fusion splicing pipe 140 is provided with an inclined end portion 120 is inclined at an angle to the connection pipe 140 The inclined end portion is formed inside the expansion joint tube 140 integrated with the connection pipe 110 while being integrally connected or installed through the 110 and the fusion bead part 130 or formed as an integral injection molded product. A pipe insertion groove 150 is formed to be inclined at the same inclination angle, and one end of each of the pipes 230 is inserted into and fixed to the inclined pipe insertion groove 150 inside the expansion joint tube 140. .

At this time, the inclination angle of the pipe insertion groove 150 is inclined at an angle of 20 to 40 degrees, so that the insertion pipe 110 can be easily inserted, the stepped portion of the coupling bolt 190 can be easily fastened. To form.

Subsequently, pressure rings of the metal material or the synthetic resin material installed on the outer circumferential surfaces of the both side pipes 230 in the state in which the metal ring 160 for binding reinforcement is installed at the periphery of the outer inclined end portion 120 of the expansion joint pipe 140. (200), the locking jaw 180 is formed at the end via the sealing packing 170 is installed on the pipe 230 as the coupling bolt 190 and the nut 210 of the expansion joint 140 By coupling with the metal ring for binding reinforcement 160 installed on the outer inclined end portion is simply connected to both side pipe 230.
