본 고안은 금속나선관을 배관접속할때 사용되는 연결구에 관한 것으로 본 출원인에 의하여 선출원된 금속나선관용 연결구(실용신안등록출원 제91-181609호)의 조립구조를 개선하여 조립성과 생산성을 향상하면서 나선관에 작용하는 인장력에 대하여 패킹의 결속력을 견고하게 유지할 수 있고, 특히 관체에 통전을 가능하게 하므로서 동절기에 관내가 결빙되었을때 통전에 의한 해빙이 가능하게 되는 금속나선관용 연결구에 관한 것이다.The present invention relates to a connector used for connecting a metal spiral pipe, and improves the assembly structure and productivity of the metal spiral pipe connector (utility model registration application No. 91-181609), which has been filed by the applicant, The present invention relates to a connector for a metal spiral pipe that can firmly maintain a binding force of a packing against a tensile force acting on a pipe, and in particular, enables to energize the pipe, thereby enabling thawing by power when the pipe is frozen in winter.

종래의 금속나선관에 적용되었던 연결구가 강한 조임에도 불구하고 관체가 당겨지면 패킹이 파손되는등 수밀성이 낮고 고압관로의 설비에 사용할 경우 많은 문제점이 있었던 것을 해결하기 위하여 고안된 상기 선출원은 적당한 유연성을 가진 고무나 합성수지로 성형되는 나선패킹에 금속나선관과 체결될수 있는 암나사부를 형성하고, 이 암나사부의 중앙에는 나선패킹의 유연성에 기인하는 강도사아의 취약점을 보완하기 위하여 금속나선링을 매입하여 패킹의 슬립으로 인한 결속력의 저하를 방지할 수 있는 것이다.In spite of the strong tightening of the connector used in the conventional metal spiral pipe, when the tube is pulled, the packing is damaged, such as the packing is low, the water tightness is low, and the first application designed to solve the many problems when used in the installation of the high-pressure pipeline has a suitable flexibility Spiral packing made of rubber or synthetic resin forms a female threaded part that can be fastened with a metal spiral tube, and at the center of the female threaded part, a metal spiral ring is embedded to compensate for the weakness of the strength thread caused by the flexibility of the spiral packing. This can prevent the deterioration of the binding force.

이러한 선고안은 완벽한 수밀을 유지할 수 있는 사용상의 효과는 인정되는 것이지만 나선패킹이 제작에는 보완되어야할 사항이 있는 것이다.Such a declaration would be recognized for its effectiveness in maintaining perfect watertightness, but there is a need for spiral packing to be supplemented in production.

이는 비금속인 나선패킹에 별도의 금속나선링을 결합시키는 방법에 관여되는 것으로 결합방법의 예를 들면 나선패킹에 나선링이 삽입될 수 있는 공간을 형성하여 나선링을 삽입하거나, 나선패킹의 성형시에 금속나선링을 매설하여 일체로 형성하는 방법을 들을 수 있다.This is related to a method of joining a separate metal spiral ring to a non-metallic spiral packing, which forms a space in which a spiral ring can be inserted into a spiral packing, for example, to insert a spiral ring or to form a spiral packing. And a method of embedding a metal spiral ring in an integral form.

전자의 경우에 있어서는 금속나선링이 삽입될 수 있는 공간을 나선패킹의 내측에 형성하는데 따르는 금형의 복잡성으로 인한 원가 상승의 요인과 금속나선링을 나선패킹에 삽입하기 위한 작업의 어려움으로 인한 불편함과 생산성이 저하되고, 후자의 경우도 역시 제작금형이 복잡하여 원가상승의 요인이 내재되어 있는 것이다.In the former case, it is inconvenient due to the cost increase due to the complexity of the mold that forms the space where the metal spiral ring can be inserted inside the spiral packing, and the difficulty of inserting the metal spiral ring into the spiral packing. In the latter case, too, the production mold is complicated, which leads to a cost increase.

또한, 금속나선관에 있어서는 전술한 수밀성의 유지와 더불어 동절기에 관로내부의 유체가 결빙되었을때 이를 신속하게 해빙시켜서 유체의 원활한 수송과 동파를 방지할 수 있도록 배려되어야 한다.In addition, in the case of the metal spiral tube, in addition to maintaining the above watertightness, when the fluid inside the pipeline freezes during the winter, it should be taken into consideration so as to prevent the smooth transportation and freezing of the fluid.

이러한 해빙방법으로 관로 양측에 전류를 통전시켜 얼음을 녹이는 방법이 일반적으로 사용되고 있는데, 상기 선고안에서는 금속나선관과 결합되는 대향측 관로가 부양도체인 나선패킹과 조임너트에 밀착되는 패킹에 의하여 전류의 통전이 불가능하여 연결구 부분의 해빙에 애로가 있는 것이다.As a method of thawing, a method of melting ice by energizing current on both sides of a pipeline is generally used.In the above declaration, an opposite pipeline coupled to a metal spiral tube is connected to a spiral packing, which is a supporting conductor, and a packing tightly adhered to a tightening nut. It is impossible to energize, which causes difficulties in thawing the connector.

연결구 부분에서 통전에 의한 해빙이 가능하게 되는 기술로서는 본출원인에 의하여 선등록된 금속주름관 연결구(실용신안등록 제54688호)가 알려져 있다.As a technique for enabling thawing by energization at the connector part, a metal wrinkle pipe connector (Utility Model Registration No. 54688) registered in advance by the present applicant is known.

이것은 주름관의 요구에 절곡된 걸림부가 형성된 판상의 금속링을 끼워넣어 조임너트와 소켓관을 통하여 전류가 흐르루 있게한 것이나 이러한 선고안의 구성은 요구가 반복되는 원형으로 형성되는 주름관의 경우에 적합한 것으로서 본원과 같은 나선주름관에서는 수밀성과 조임너트 체결시 금속링이 패킹의 일측에 편증되게 밀착되어 체결력이 약하여 적용하기가 용이치 못한 것이다.This is made by inserting a plate-shaped metal ring formed with a bent portion bent to the demand of the corrugated pipe so that current flows through the fastening nut and the socket pipe. However, the constitution of the sentence is suitable for the case of the corrugated pipe formed in a circular shape where the request is repeated. In the spiral corrugated pipe as described herein, the metal ring is eccentrically adhered to one side of the packing when the watertightness and the tightening nut are fastened, so that the fastening force is weak, and thus it is not easy to apply.

본 고안은 이와 같은 종래의 모든 문제점들을 해결하여 항상된 결속력으로 압력의 영향으로 인한 누수를 방지하고 보다 효과적인 해빙 작업을 할수 있게되는 금속나선관용 연결구를 제공하기 위한 것이다.The present invention is to provide a connector for a metal spiral pipe that can solve all the problems of the prior art to prevent the leakage caused by the influence of pressure with a constant binding force and to work more effectively thawing.

이와 같은 목적을 달성하기 위한 본 고안의 실시예를 첨부된 도면과 관련하여 상세히 설명하면 다음과 같다.Embodiments of the present invention for achieving the above object will be described in detail with reference to the accompanying drawings.

상기 테이퍼진 내면(11)은 나선패킹(3)이 삽입되면서 양호한 압착력을 부여한다.The tapered inner surface 11 gives a good compressive force as the spiral packing 3 is inserted.

나선패킹(3)은 약간의 신축성을 가진 고무, 또는 합성수지재로 제작되면서 소켓(1)의 내면(11)과 일치하는 기울기를 가진 외면(31)의 육후부(32)에 플랜지(33)를 형성하고 중앙에는 금속나선관(5)의 나선(51)과 일치하는 암나사부(34)를 축방향으로 관통하여 형성된다.Spiral packing (3) is made of a flexible rubber or synthetic resin material while the flange 33 on the rear end 32 of the outer surface 31 having a slope matching the inner surface 11 of the socket (1) It forms in the center and penetrates the female screw part 34 corresponding to the spiral 51 of the metal spiral tube 5 in the axial direction.

나선패킹(3)의 암나사부(34)는 금속나선관(5)과 나사로 결합된 상태에서 소켓(1)과 조임너트(2)의 체결력에 의하여 외면(31)이 소켓(1)의 경사진 내면(11)의 가압력으로 금속나선관(5)에 밀착되는 것이 가능하게 되는 것이다.The female thread part 34 of the spiral packing 3 is inclined to the socket 1 by the fastening force of the socket 1 and the fastening nut 2 in a state where the screw thread is screwed with the metal spiral tube 5. It is possible to be in close contact with the metal spiral tube 5 by the pressing force of the inner surface 11.

플랜지(33)의 일측면은 원주면으로 부터 암나사부(34)가 형성된 중앙을 향하여 점차 돌출되는 경사면(35)이 형성되어 결합할때 나선링(5)에 점진적으로 면접촉을 하면서 압착되어 효과적인 수밀성을 제공한다.One side surface of the flange 33 is formed by an inclined surface 35 which gradually protrudes from the circumferential surface toward the center where the female thread portion 34 is formed, and is effectively pressed while gradually making a surface contact with the spiral ring 5. Provide watertightness.

나선링(4)은 금속나선관(5)에 결합되는 암나사부(41)가 형성되어 나선관(5)과 결합된 상태에서 조임너트(2)의 내벽면(21)에 밀착되어 접촉되므로써 소켓(1)에 체결된 조임너트(2)와 금속나선관(5)사이에 통전이 가능하게 된다.The spiral ring 4 has a female threaded portion 41 coupled to the metal spiral tube 5 and is brought into close contact with the inner wall surface 21 of the tightening nut 2 while being coupled with the spiral tube 5 so that the socket It is possible to energize between the tightening nut 2 fastened to (1) and the metal spiral tube 5.

상기 나선링(4)은 신축성 재질인 나선패킹(3)의 강도와 슬립을 방지하기 위하여 일정두께 이상으로 제작하는 것이 바람직한 것으로 그 두께는 연결구의 크기를 고려한 설계로 산출될 수 있는 것이며, 내식성을 고려하여 청동이나 황동을 비롯하여 적당한 내마모성을 가진 양도체의 비철금속이 사용된다.The spiral ring (4) is preferably manufactured to a predetermined thickness or more in order to prevent the strength and slip of the elastic packing (3) of the elastic material, the thickness can be calculated by the design considering the size of the connector, corrosion resistance In consideration, nonferrous metals of good conductors, including bronze and brass, with adequate wear resistance are used.

이와 같은 본 고안은 금속재 나선링이 금속나선관에 결합되어 조임너트에 밀착되면서 나선패킹의 일측면을 견고하게 지지하여 관로내에서 발생되는 유체의 압력과 외부에서 작용하는 인장 및 압축력으로 부터 나선패킹의 변형을 방지하여 높은 수밀성을 발휘하게 되는 것이며 금속나선관과 결합측 배관의 통전이 가능하게 되어 통전에 의한 해빙작업을 보다 신속하고 용이하게 할 수 있게 되는 것이다.The present invention is a spiral packing from the pressure of the fluid generated in the conduit and the tension and compression force acting on the outside by firmly supporting one side of the spiral packing while the metallic spiral ring is tightly coupled to the metallic spiral tube and tightly attached to the tightening nut. The high watertightness is exhibited by preventing the deformation of the metal spiral tube, and the energization of the metal spiral pipe and the coupling side pipe is made possible, so that the thawing operation by the energization can be made more quickly and easily.
