Abstract

A flange connection joint is provided to prevent fluid from being leaked through the flange connection joint by coupling a connection pipe with a joint using a bolt to improve water-tight characteristics of the flange connection joint. A flange connection joint comprises a joint body(1), an outer flange(2), and an inner core(3), which are integrally formed with each other. A connection pipe is installed between the outer flange and the inner core by interposing a rubber packing(4). A bolt(6) having a gasket(5) is inserted into a perforation hole(3a) of the inner core. The bolt extends through a perforation hole of the connection pipe and a perforation hole(2a) of the outer flange. A nut(7) is screw-coupled with the bolt and the joint body is coupled with the outer flange by the bolt.

플렌지 접합 이음쇠{A flange connected joint}  Flanged joint joint

본 발명은 이음쇠와 연결관을 일체형으로 구성한 플렌지 접합 이음쇠에 관한 것이다.  The present invention relates to a flanged joint fitting in which the fitting and the connecting pipe are integrally formed.

기존의 이음쇠는 이음쇠내부에 연결관이 삽입되는 구조인바, 중량이 무거워 시공성이 나쁘고 수밀성이 떨어지는 문제점이 있었다.  Existing fittings have a structure in which a connector is inserted into the fitting, so that the weight is heavy so that the workability is poor and the watertightness is inferior.

본 발명은 플렌지 접합 이음쇠에 관한 것으로, 보다 상세하게는 연결관(파이프)과 이음쇠를 일체형구조로 형성하여 체결력을 강화한 이음쇠에 관한 것이다.  The present invention relates to flange joint fittings, and more particularly, to a fitting in which a coupling pipe (pipe) and a fitting are formed in an integrated structure to strengthen a fastening force.

종래에는 이음쇠내부로 연결관이 삽입되는 방식인바, 연결관이 삽입되는 깊이 이상으로 이음쇠본체가 길게 됨에 따라 중량이 무거워서 이동성이나 시공 상에 어려움이 많을 뿐만 아니라 패킹압착방식을 사용함으로서 고압 시에는 수밀성이 떨어지는 등의 문제점이 있었다.  Conventionally, it is a method of inserting a connector into a fitting, and as the fitting body becomes longer than the depth into which the connector is inserted, the weight is heavy, and there are many difficulties in mobility or construction, as well as watertightness at high pressure by using a packing crimping method. There was a problem such as falling.

고압용 이음쇠의 경우, 이음쇠본체(1)와 외측플렌지(2) 및 내경부코어(3)의 결합 형인바, 외측플렌지(2)와 내경부코어(3) 사이에 고무패킹(4)을 개재하여 삽입된 연결관(30)을 수직으로 전공한 후 상기 내경부코어(3)측의 천공부(3a)를 통해 가스켓(5)을 개재한 볼트(6)를 삽입한 후 연결관(30)의 천공부(30a)를 관통하여 외측플렌지(2)의 천공부(2a)를 관통한 다음 너트(7)로 체결한 후 본체(1)와 외측플렌지(2)를 볼트(6)로 체결하고, 저압용 이음쇠(20)의 경우, 이의 구조는 본체(11)와 외측플렌지(12)의 결합형인바, 외측플렌지(12)와 연결관(30)을 결합한 후 상기의 외측플렌지(12)에 천공부(12a)를 형성하고, 아울러 연결관(30)에도 천공부(30a)를 형성한 후 상기 연결관(30)의 천공부(30a)로 가스켓(5)을 개재한 볼트(6)를 삽입하여 외측플렌지(12)의 천공부(12a)를 관통시킨 후 너트(7)로 체결한 후 본체(1)와 외측플렌지(12)를 볼트(6)로 체결하는 플렌지 접합 이음쇠이다.  In the case of high-pressure fittings, the fitting body of the fitting body 1, the outer flange 2, and the inner diameter core 3 is interposed between the outer flange 2 and the inner diameter core 3 with a rubber packing 4 interposed therebetween. After vertically majoring the insertion pipe 30 is inserted into the bolt (6) via the gasket (5) through the perforation (3a) of the inner diameter core (3) side connecting pipe 30 After penetrating through the perforated portion (30a) of the outer flange (2a) through the perforated portion (2a) and then tightened with a nut (7) and then fastening the main body 1 and the outer flange (2) with a bolt (6) , In the case of the low pressure fitting 20, its structure is a coupling type of the main body 11 and the outer flange 12, the outer flange 12 and the coupling pipe 30 is coupled to the outer flange 12 above.
