Abstract

A fusion bonded-type connector improving fusion bonded efficiency is provided to be fused and connected easily to a synthetic resin pipe having various outer diameter differences and an uneven surface. In a fusion bonded-type connector(100a) improving fusion bonded efficiency, a heating wire(112a) is arranged along the inner surface, and formed like a cylinder or semi-cylinder type. The connection member has a main body(110a) fused in a synthetic resin pipe. A hollow(120a) guiding the compressed air is formed inside the main body along the heating wire, and forces resin melted by the heating wire to the synthetic resin pipe in the course of a fusing process.

Description

융착 성능이 향상된 융착식 연결부재{FUSION BONDED-TYPE CONNECTOR IMPROVING FUSION BONDED EFFICIENCY}FUSION BONDED-TYPE CONNECTOR IMPROVING FUSION BONDED EFFICIENCY}

본 발명은 융착식 연결부재에 관한 것으로서, 더욱 상세하게는 내주면에 전열선이 배치된 본체의 내부에 전열선을 따라 형성되고, 압축에어가 유입되는 중공부를 형성함으로써, 융착 작업 시 중공부에 압축에어가 유입되게 하여 용융된 수지를 합성수지관의 외경 측으로 거동(擧動)되게 하여 외경의 공차가 큰 합성수지관의 연결, 또는 외경 표면이 불규칙한 합성수지관에 연결부재가 용이하게 융착될 수 있게 하는 융착 성능이 향상된 융착식 연결부재에 관한 것이다. The present invention relates to a fusion-splicing member, and more particularly, formed on the inner circumferential surface of the main body in which the heating wire is disposed along the heating wire, and forming a hollow portion through which the compressed air flows, thereby compressing the air into the hollow portion during the fusion operation. Fusion performance that allows molten resin to flow to the outer diameter side of the synthetic resin pipe so that the connection of the synthetic resin pipe with a large tolerance of the outer diameter or the connecting member can be easily fused to the synthetic resin pipe with an irregular outer surface An improved fusion splicing member is provided.

일반적으로, 합성수지관은 관 자체에서 용출되는 물질이 거의 없고, 부식될 염려가 없으며, 인위적인 손상을 가하지 않는 한 수명이 반영구적일 뿐만 아니라, 자재비 및 시공비용이 저렴하다는 장점이 있어, 가스관, 수도관, 하수관, 배수관 등 다양한 용도로 이용되고 있다. 가스관과 수도관은 가스(gas)가 가지는 특성상 관의 두께와 내경 및 외경이 일정하게 제작되지만, 하수관 및 배수관은 제작환경에 따라서 두께, 내경 및 외경 등에 허용 공차자체가 크게 제작된다. In general, synthetic resin pipes have almost no material eluting from the pipes themselves, are not corrosive, and have the advantages of being semi-permanent unless they are artificially damaged, and having low material and construction costs. It is used for various purposes such as sewer pipes and drain pipes. Gas pipes and water pipes are made of a constant thickness and inner diameter and outer diameter of the gas due to the nature of the gas (gas), but sewage pipes and drain pipes are manufactured with a large allowable tolerance itself, such as thickness, inner diameter and outer diameter depending on the production environment.

이러한 합성수지관은 일정한 길이로 제작되기 때문에 현장에서는 원하는 길 이를 얻기 위해서 서로 연결하여 사용되고, 또한 주 배관을 흐르는 유체를 각각의 사용처로 공급하기 위한 가지관을 연결하여 사용되는데, 그 연결 방법으로는 다양한 방법이 제공되고 있으나 열을 이용한 방법으로는 대부분 전기융착(Electro-Fusion; EF)법이 이용되고 있는 실정이다. Since these synthetic resin pipes are manufactured to a certain length, they are used to be connected to each other in the field in order to obtain desired length, and also to connect branch pipes for supplying fluid flowing through the main pipe to each use place. Although methods have been provided, most of the methods using heat have been used in the electro-fusion (EF) method.

도 1a는 종래 원통형 연결부재를 나타낸 단면도이며, 그리고 도 1b는 종래 반원통형 연결부재를 나타낸 단면도이다.Figure 1a is a cross-sectional view showing a conventional cylindrical connecting member, and Figure 1b is a cross-sectional view showing a conventional semi-cylindrical connecting member.

도시된 바와 같이, 연결부재(100a, 100b)는 원통 형상의 본체(110a), 또는 반 원통 형상의 본체(110b)를 구비한다. 전술한 본체(110a, 110b)의 내주면 상에는 본체(110a, 110b)의 내주면을 따라 전열선(112a, 112b)이 배치된다. 이러한 전열선(112a, 112b)의 각각의 단부는 본체(110a, 110b)의 외주면 상으로 배치되는 접지단자(114a, 114b)와 연결된다. As shown, the connection members 100a and 100b include a cylindrical body 110a or a semi-cylindrical body 110b. The heating wires 112a and 112b are disposed along the inner circumferential surfaces of the main bodies 110a and 110b on the inner circumferential surfaces of the main bodies 110a and 110b. Each end of the heating wires 112a and 112b is connected to the ground terminals 114a and 114b disposed on the outer circumferential surfaces of the main bodies 110a and 110b.

바람직하게는 전열선(114a, 114b)의 방사상 일측은 본체(110a, 110b)의 내주면 상에 매몰되고, 전열선(114a, 114b)의 방사상 타측은 본체(110a, 110b)의 내주면 상으로 노출된다. Preferably, one radial side of the heating wires 114a and 114b is buried on the inner circumferential surfaces of the main bodies 110a and 110b, and the other radial sides of the heating wires 114a and 114b are exposed onto the inner circumferential surfaces of the main bodies 110a and 110b.

한편, 본체(110a, 110b)의 내부에는 전열선(114a, 114b)을 따라 압축에어가 안내되는 중공부(120a, 120b)가 형성된다. 이러한 중공부(120a, 120b)는 전열선(112a, 112b) 및 본체(110a, 110b)의 외주면 상에 간섭되지 않게 본체(110a, 110b) 내부에 형성된다. Meanwhile, hollow parts 120a and 120b through which the compressed air is guided along the heating wires 114a and 114b are formed inside the main bodies 110a and 110b. The hollow parts 120a and 120b are formed inside the main bodies 110a and 110b so as not to interfere with the heating wires 112a and 112b and the outer circumferential surfaces of the main bodies 110a and 110b.

또한 본체(110a, 110b)의 외주면 상에는 안내돌기(130a, 130b)가 일체로 형성되고 안내돌기(130a, 130b)에는 압축에어가 유입되는 안내부(132a, 132b)가 중공부(120a, 120b)와 연결되게 형성되는데, 안내돌기(130a, 130b)에는 압축에어가 주입되는 주입호스(도시되지 않음)가 연결된다. In addition, the guide protrusions 130a and 130b are integrally formed on the outer circumferential surfaces of the main bodies 110a and 110b, and the guide parts 132a and 132b through which compressed air flows into the guide protrusions 130a and 130b are hollow parts 120a and 120b. Is formed to be connected to, guide hoses (130a, 130b) is connected to the injection hose (not shown) is injected compressed air.

즉, 안내부(132a, 132b)를 통해 유입된 압축에어는 중공부(120a, 120b) 측으로 안내되고, 중공부(120a, 120b) 측으로 안내된 압축에어는 고주파전류가 인가된 전열선(112a, 112b)에 의해서 용융된 용융수지를 연결하고자 하는 합성수지관(P1, P2, P3) 측으로 거동되게 한다. That is, the compressed air introduced through the guide parts 132a and 132b is guided to the hollow parts 120a and 120b, and the compressed air guided to the hollow parts 120a and 120b is applied to the heating wires 112a and 112b to which a high frequency current is applied. ) Into the synthetic resin pipe (P1, P2, P3) to be connected to the molten molten resin.

하기에는 전술한 바와 같이 형성된 융착 성능이 향상된 융착식 연결부재(100)의 사용상태를 간략하게 설명한다. Hereinafter, the state of use of the fusion splicing member 100 with improved fusion performance formed as described above will be briefly described.

먼저, 어느 하나의 합성수지관(P1)과 또 다른 합성수지관(P2)을 연결하기 위해서는 원통 형상의 본체(110a)의 내주면 양측에 각각 합성수지관(P1, P2)을 삽입시킨다. 이렇게 연결하고자 하는 합성수지관(P1, P2)이 원통 형상의 본체(100a)에 삽입되면 융착기계(도시되지 않음)의 케이블(도시되지 않음)을 접지단자(114a)에 연결시킨 상태 하에서 융착기계를 작동시키면 케이블 및 접지단자(114a)를 통해 전열선(112a)에 고주파 전류를 인가시킨다. First, in order to connect one synthetic resin pipe P1 and another synthetic resin pipe P2, the synthetic resin pipes P1 and P2 are respectively inserted into both inner circumferential surfaces of the cylindrical main body 110a. When the synthetic resin pipes P1 and P2 to be connected are inserted into the cylindrical main body 100a, the welding machine is connected under a state in which a cable (not shown) of a welding machine (not shown) is connected to the ground terminal 114a. When activated, a high frequency current is applied to the heating wire 112a through the cable and the ground terminal 114a.

전술한 바와 같이, 전열선(112a)에 고주파 전류가 인가되면, 본체(110a)의 내주면 상으로 매몰된 전열선(112a)은 본체(110a)의 내주면 표면을 용융시키고, 본체(110a)의 내주면 외부로 노출된 전열선(112a)은 본체(110a)에 삽입된 합성수지관(P1, P2)의 외주면을 용융시킨다. 이때, 전열선(112a)으로 인가되는 고주파 전류를 차단하고, 안내돌기(130a)를 통해 압축에어를 공급하면, 압축에어는 안내부(132a)를 통해 중공부(120a)로 유입되고, 중공부(120a)로 유입된 압축에어는 본체(110a) 내주면에 용융된 수지를 합성수지관(P1, P2) 측으로 거동시켜 합성수지 관(P1, P2)의 외주면 상에 용융된 수지와 융착되게 한다. 즉, 압축에어는 중공부(120a)를 부풀려 본체(110a) 내주면에 용융된 수지를 합성수지관(P1, P2) 측으로 거동시키게 된다. 이렇게 압축에어에 의해서 부풀려지는 중공부(120a)는 연결하고자 하는 합성수지관(P1, P2)의 외경의 오차로 인해 본체(110a)의 내주면에 접촉되지 않아도 용이하게 융착될 수 있다. As described above, when a high frequency current is applied to the heating wire 112a, the heating wire 112a buried on the inner circumferential surface of the main body 110a melts the surface of the inner circumferential surface of the main body 110a and moves outward to the inner circumferential surface of the main body 110a. The exposed heating wire 112a melts the outer circumferential surfaces of the synthetic resin pipes P1 and P2 inserted into the main body 110a. At this time, when the high-frequency current is applied to the heating wire (112a), and supply compressed air through the guide projection (130a), the compressed air is introduced into the hollow portion (120a) through the guide portion (132a), hollow portion ( The compressed air introduced into 120a may cause the resin melted on the inner circumferential surface of the main body 110a toward the synthetic resin pipes P1 and P2 to be fused with the melted resin on the outer circumferential surfaces of the synthetic resin pipes P1 and P2. That is, the compressed air inflates the hollow portion 120a to cause the resin melted on the inner circumferential surface of the main body 110a to move toward the synthetic resin pipes P1 and P2. Thus, the hollow portion 120a inflated by the compressed air may be easily fused without contacting the inner circumferential surface of the main body 110a due to an error in the outer diameter of the synthetic resin pipes P1 and P2 to be connected.

한편, 반 원통 형상의 본체(100b) 역시 합성수지관(P3)에 밀착시킨 상태 하에서 동일한 방법으로 융착 연결할 수 있으며, 따라서 불규칙한 합성수지관(P3) 표면에도 용이하게 융착될 수 있다. On the other hand, the semi-cylindrical body (100b) can also be fusion-bonded in the same manner under the state in close contact with the synthetic resin pipe (P3), and thus can be easily fused to the irregular synthetic resin pipe (P3) surface.
