Description

합성수지관 연결용 열선링{hot wiring for synthetic resins pipe coupling}Hot wiring for synthetic resins pipe coupling

본 발명은 합성수지관 연결용 열선링에 관한 것으로, 특히 열선판의 형상을 사행선으로 형성하여 융착이 양호한 접속상태를 이룰 수 있도록 한 합성수지관 연결용 열선링에 관한 것이다.The present invention relates to a hot wire ring for connecting a synthetic resin pipe, and more particularly, to a hot wire ring for connecting a synthetic resin pipe to form a shape of the hot wire plate in a meandering line to achieve a good connection state.

일반적으로 배수로관으로 사용되는 합성수지관을 연결할 때는 긴밀히 접합하여 수밀성을 유지시키도록 연결해야 하며, 만약 합성수지관의 연결상태가 불량하면 온도변화에 따른 합성수지관의 신축작용에 의해 합성수지관의 연결부위가 더욱 악화되어 이 부분에서 누수가 발생되고, 궁극적으로 합성수지관으로부터 유출된 오폐수로 인하여 지하수 오염 및 토양의 오염과 같은 환경오염을 야기하게 된다.In general, when connecting a synthetic resin pipe used as a drainage pipe, it must be connected closely to maintain watertightness. If the connection state of the synthetic resin pipe is poor, the connection portion of the synthetic resin pipe is changed by the expansion and contraction of the synthetic resin pipe due to temperature change. Even worse, water leakage occurs in this area, and ultimately, the wastewater flowing out of the synthetic resin pipe causes environmental pollution such as groundwater contamination and soil contamination.

상기한 바와 같은 문제점을 해결하기 위해 연결될 합성수지관간에 열선링을개재시킨 후 유압장치 및 기타 방법을 이용하여 합성수지관을 밀착시킴과 동시에 전기를 통전시켜 열선링을 발열시켜 융착시키도록 한 방법이 특허 제2001-5467호로 출원된 바 있다.In order to solve the problems as described above, between the synthetic resin pipes to be connected between the heating method by using a hydraulic device and other methods to close the synthetic resin pipes and at the same time by energizing the heating wire ring to heat and fusion It was filed in 2001-5467.

여기서, 상기한 바와 같은 연결방법에 의한 합성수지관 연결은 일체화되어 견고하면서 양호한 수밀성을 가지며, 연결되는 장점이 있으나, 보다 더 양호한 열선링의 구조를 개발할 필요성이 제기되었다.Here, the synthetic resin pipe connection by the connection method as described above has a strong and good watertightness is integrated, but there is an advantage to be connected, but there is a need to develop a structure of a better heat wiring ring.

이에, 상기한 바와 같은 제반 문제점을 해결하기 위해 본 발명의 출원인은 실용신안등록출원 제2001-6454호(합성수지관 연결용 열선링)를 출원하였다.Accordingly, in order to solve the above problems, the applicant of the present invention has applied for utility model registration application No. 2001-6454 (heating ring for connecting a synthetic resin pipe).

즉, 상기한 바와 같은 종래의 합성수지관 연결용 열선링은 연결될 두 합성수지관의 사이에 개재시켜 전기 발열로 융착시키는 열선링에 있어서, 열선만으로 이루어진 얇은 열선판의 내외측단에 연결될 두 합성수지관의 연결부 내외측면을 지지하는 내외부 지지링이 결합된 것을 특징으로 한다.In other words, the conventional synthetic resin pipe connection heating wire ring as described above in the heating wire ring fusion between the two synthetic resin pipes to be connected by electric heat, the two synthetic resin pipes to be connected to the inner and outer ends of the thin hot wire plate consisting of only the heating wire Inner and outer support ring for supporting the inner and outer sides of the connection is characterized in that it is coupled.

그러나, 상기한 바와 같은 구성으로 이루어진 종래의 합성수지관 연결용 열선링은 단자선에 전기를 공급하면 열선판의 열선으로 전류가 균일하게 공급되어야 융착이 원활하게 이루어지는데, 동일전류를 공급하더라도 저항의 특성상 저항이 작은쪽으로 전류가 흘러, 열선판의 열선이 전체적으로 균일한 온도분포를 이루지 못하고 어느 특정 부분에만 집중하여 불균일한 온도분포를 이루는 문제와 회로구성상 병렬회로 구성으로 인하여 전류 통전시 과도한 전력소모를 필요로 하게 되는 문제점이 있었다.However, in the conventional composite resin pipe connection heating wire ring having the configuration as described above, when the electric current is supplied to the terminal line, the current is uniformly supplied to the hot wire of the hot wire plate to smooth the fusion. Due to the characteristic, the current flows toward the lower side of the resistor, so that the heating wire of the heating plate does not form a uniform temperature distribution as a whole, and concentrates on only a specific part to achieve a non-uniform temperature distribution.

This is because it is widely used as a resistance wire for.

상기 열선판(11)의 결합상태는 제조시 열선판(11)을 금형에 위치시키고 그 외주와 내부로 수지를 주입하여 열선판(11)의 내외측단이 내외부 지지링(12)에 매립되어 결합되거나 또는 내부 지지링(12)의 외주면 중앙부와 외부 지지링(12)의 내측면 중앙에 결합홈을 가공하여 이 결합홈에 열선판(11)의 내외측단을 끼워 조립할 수 있다.In the combined state of the hot wire plate 11, the hot wire plate 11 is placed in a mold during manufacture and resin is injected into the outer circumference and the inside thereof so that the inner and outer ends of the hot wire plate 11 are embedded in the inner and outer support rings 12. The coupling groove may be machined in the center of the outer peripheral surface of the inner support ring 12 and the center of the inner surface of the outer support ring 12 to assemble the inner and outer ends of the heating wire 11 into the coupling groove.

이때, 상기 열선판(11)의 내외측단이 내외부 지지링(12)의 결합홈으로부터 잘 빠지는 것을 방지하기 위해 억지끼움식으로 결합시킴과 동시에 상기 열선판(11)의 내외측단에 걸림턱 기능을 하는 고정링을 연결할 수도 있다.At this time, in order to prevent the inner and outer ends of the heating coil plate 11 from falling out of the coupling groove of the inner and outer support rings 12, the locking jaw is coupled to the inner and outer ends of the heating coil plate 11 at the same time.

This is to prevent the phenomenon that is concentrated in this one place.

또한, 상기 열선판(11)은 개방된 구조를 가지며 일측이 절단되어 있고, 단자선(13)은 절단된 열선판(11)의 양단에 연결된다.In addition, the hot wire plate 11 has an open structure and one side is cut, and the terminal line 13 is connected to both ends of the cut hot wire plate 11.

이는 단자선(13)에 공급하는 전기가 고른 분포로 전달되도록 하여 열선(11a)의 각 부분에 균일한 온도분포를 가지도록 하기 위함이다.This is to ensure that the electricity supplied to the terminal line 13 is transmitted in an even distribution so as to have a uniform temperature distribution in each part of the heating line 11a.

상기한 바와 같은 구성으로 이루어진 본 발명에 따른 합성수지관 연결용 열선링은 연결될 합성수지관(20)의 사이에 열선링(10)을 개재시킨 후 유압 연결장치나 수동 연결장치를 이용하여 합성수지관(20)을 밀착시키는 한편, 밀착되는 양측 합성수지관(20)의 단부는 내외부 지지링(12)의 사이로 삽입되어 열선판(11)을 사이에 두고 밀착된다.Synthetic resin pipe connection hot wire ring according to the present invention made of a configuration as described above through the heating wire ring 10 between the synthetic resin pipe 20 to be connected to the synthetic resin pipe 20 using a hydraulic connection device or a manual connection device ) And the ends of both synthetic resin pipe 20 to be in close contact with each other is inserted between the inner and outer support rings 12 to be in close contact with the hot wire plate 11 therebetween.

이 상태에서 상기 열선판(11)의 단자선(13)에 전기를 통전시키면, 열선(11a)은 발열되면서 양측 합성수지관(20)의 단부를 용융시키고, 양측 합성수지관(20)의 단부에서 용융된 용융물은 열선판(11)의 사이를 통해 서로 혼합됨과 동시에 합성수지관(20)의 벽면 내부에 형성된 공간을 메우게 된다.In this state, when electricity is supplied to the terminal line 13 of the heating wire plate 11, the heating wire 11a generates heat and melts the ends of both synthetic resin tubes 20, and melts at the ends of both synthetic resin tubes 20. The melts are mixed with each other through the hot wires 11 and at the same time fill the space formed inside the wall surface of the synthetic resin tube 20.

특히, 상기 열선판(11)이 하나의 사행선으로 이루어지며, 등간격으로 동일평면상에 배치되는 열선(11a)으로만 형성되기 때문에 양측 용융물은 더욱 용이하게 혼합되며, 일정시간이 경과한 후 단자선(13)의 전기를 차단시키면 용융물은 경화되며 양측 합성수지관(20)은 하나의 몸체로 견고하게 연결될 뿐만 아니라 용융물이 혼합되면서 내외부 지지링(12)의 틈새로도 유입되어 용융물 경화후 그 틈새가 완전히 밀봉되므로 궁극적으로 완벽한 합성수지관(20)의 수밀성을 가지는 작용효과가 있다.In particular, since the hot wire plate 11 is made of one meandering line, and formed only by hot wires 11a disposed on the same plane at equal intervals, both melts are more easily mixed, and after a predetermined time has elapsed. When the electricity of the terminal line 13 is cut off, the melt is cured, and both synthetic resin pipes 20 are firmly connected to one body, and the melt flows into the gap of the inner and outer support rings 12 while the melt is mixed. Since the gap is completely sealed, there is an effect of ultimately having a watertightness of the perfect synthetic resin tube 20.

또한, 상기 내외부 지지링(12)이 합성수지관(20)의 연결부의 내외측면을 항상 지지하는 구조이기 때문에 더욱 견고한 결합상태가 유지되는 작용효과도 있다.In addition, since the inner and outer support rings 12 always support the inner and outer sides of the connecting portion of the synthetic resin tube 20, there is an effect of maintaining a more firmly coupled state.
