본 고안은 지하에 매몰된 도시가스배관에 사용되는 절연죠인트에 관한 것이다.The present invention relates to an insulated joint used in a city gas pipe buried underground.

절연죠인트는 신설배관과 기존의 전기방식조치를 취하지 않는 배관과의 절연 및 신규가정관의 절연을 위하여 사용되거나 공급관 교체공사구간, 루프화공사구간, 연장의 짧은 신설배관 공사구간중 별도의 절연 밸브실을 설치하지 않는 곳에 기존공급관과의 절연을 위해서 사용된다.Insulation joints are used to insulate new pipes and pipes that do not take conventional electrical measures, and to insulate new home pipes, or separate insulation valves in supply pipe replacement construction section, roof construction section, and extension new construction section. It is used to insulate the existing supply pipe where no seal is installed.

종래의 절연죠인트는 본 출원인의 실용신안등록출원 제91-5223호에 도시되며 이는 부시(2)의 연결부(3)(4)에 배관(10)(11)이 연결되고 부사(2)의 외주면에는 가이드(9)가 삽입되어 저압관에만 사용할 수 있었다.The conventional insulated joint is shown in the applicant's utility model registration application No. 91-5223 of the applicant, which is connected to the pipe 3, 4 of the bush 2, the pipe 10, 11 and the outer peripheral surface of the adverb 2 The guide 9 was inserted into it and could be used only for the low pressure pipe.

본 고안의 목적은 중압관에서 사용할 수 있도록 배관을 가이드로 연결하고 단조 및 유압프레스에 의해 체결하여 내구성이 우수한 절연죠인트를 제공하고자 하는 것이다.The purpose of the present invention is to provide an excellent insulation joint by connecting the pipe with a guide so as to be used in the medium pressure pipe and fastened by forging and hydraulic press.

본 고안을 첨부된 도면을 참조하여 하기에 설명한다.The present invention will be described below with reference to the accompanying drawings.

제1도에는 본 고안의 절연죠인트가 사시도로서 도시되는데, 배관(15) 및 (16)이 연결되며 연결부위는 방식 및 절연재인 시트몰딩 컴파운드(17)가 코팅되어 있다.1 is a perspective view of the insulated joint of the present invention, the pipes 15 and 16 are connected and the connection portion is coated with a sheet molding compound 17 which is anticorrosive and insulating material.

제2도에는 본 고안의 절연죠인트가 단면도로서 도시되는데, 배관(15)의 단부에는 환상돌기부(18)가 형성되고 배관(16)의 단부에도 환상돌기부(19)가 형성되어 있다.In FIG. 2, the insulated joint of the present invention is shown as a cross-sectional view, in which an annular projection 18 is formed at the end of the pipe 15, and an annular projection 19 is formed at the end of the pipe 16, too.

배관(15)의 환상돌기부(18)와 배관(16)의 환상돌기부(19)사이에는 절연가이드(22)가 설치되며 배관(16)의 환상돌기부(19)의 외부에는 절연가이드(21)이 설치된다.An insulation guide 22 is installed between the annular protrusion 18 of the pipe 15 and the annular protrusion 19 of the pipe 16, and an insulation guide 21 is provided outside the annular protrusion 19 of the pipe 16. Is installed.

절연가이드(21) 및 (22)는 기계적인 나일론으로 제조된다.The insulation guides 21 and 22 are made of mechanical nylon.

배관(15)의 환상돌기부(18)와 배관(16)의 환상돌기부(19)가 연결되는 외주에는 환상의 파이프가이드(20)가 위치되며 파이프가이드(20)는 단조 또는 유압프레스에 의해서 가압되어 배관(15) 및 (16)의 환상돌기부(18) 및 (19)가 절연가이드(21) 및 (22)와 압착되게 가공된다. 이들 환상돌기부(18) 및 (19)와 절연가이드(21) 및 (22) 사이에는 패킹재가 충진된다. 파이프가이드(20)와 배관(15) 및 (16)의 외주면은 시트몰딩 컴파운드(17)로 코팅된다.An annular pipe guide 20 is positioned on the outer circumference of the annular projection 18 of the pipe 15 and the annular projection 19 of the pipe 16, and the pipe guide 20 is pressurized by forging or hydraulic press. The annular projections 18 and 19 of the pipes 15 and 16 are machined to be pressed against the insulation guides 21 and 22. A packing material is filled between these annular projections 18 and 19 and the insulating guides 21 and 22. The outer circumferential surfaces of the pipe guide 20 and the pipes 15 and 16 are coated with the sheet molding compound 17.

상기와 같이 구성된 본 고안의 절연죠인트는 파이프가이드(20)가 가압되어 배관(15) 및 (16)의 연결을 견고하게 하므로 종래의 절연죠인트보다 내구성이 향상되어 중압관에서 사용될 수 있는 효과를 제공한다.Insulation joint of the present invention configured as described above is a pipe guide (20) is pressurized to strengthen the connection of the pipes (15) and (16) provides durability that can be used in the medium-pressure pipe is improved durability than conventional insulation joints do.
