Thus, coupling costs and manufacturing costs may be reduced.

Description

클립훅 체결 구조를 가진 관 이음용 플랜지 조립체Pipe Fitting Flange Assembly with Clip Hook Fastening Structure
본 발명은 마주보는 관 이음용 플랜지, 밸브이음용 플랜지, 압력용기노즐이음용 플랜지, 기계 축 등의 관을 연결하는 플랜지 등에 적용될 수 있는 관 이음용 플랜지 조립체에 관한 것으로, 보다 상세하게는 관 이음용 플랜지 외부면에 형성된 빗변 돌출부에 결합되는 볼트삽통 구멍이 형성된 클립훅과 이를 체결하는 볼트 및 너트를 포함하여 구성되는 관 이음용 플랜지 조립체에 관한 것이다.The present invention relates to a flange assembly for pipe joints that can be applied to the flange for connecting pipes, flanges for valve fittings, flanges for pressure vessel nozzle fittings, flanges for machine shafts, etc. The present invention relates to a pipe assembly flange assembly including a clip hook having a bolt insertion hole coupled to a hypotenuse projecting portion formed on an outer surface of a flange, and a bolt and nut fastening thereto.
일반적으로 다양한 육상플랜트사업, 조선사업, 해상플랜트사업에서 사용되는 시스템을 구성하기 위해서는 파이프, 밸브, 압력용기노즐류, 각종계기를 연결하는 것이 필요하다. 파이프를 연결하기 위해서는 파이프의 말단부 외주연 전둘레를 따라 용접이나 브레이징 등의 영구적인 접합방법이 견고하고 경제적일 수 있지만 탈착이 반드시 필요한 부분이나 상품화된 밸브, 축, 각종 유체 기계 노즐, 부품들이 설치되는 곳은 플랜지와 개스킷으로 구성된 연결방식이 필수적일 때가 많고 또 사용하기에도 편리하다.In general, it is necessary to connect pipes, valves, pressure vessel nozzles, and various instruments to form a system used in various land plant, shipbuilding, and offshore plant projects. In order to connect the pipes, permanent joining methods such as welding or brazing along the outer periphery of the end of the pipe may be robust and economical, but the parts that need to be detached, commercialized valves, shafts, and various fluid machine nozzles and parts are installed. Often, a connection consisting of a flange and a gasket is essential and convenient to use.
파이프와 플랜지와의 결합 방식으로는 일반적으로, 나사 박음식, 맞대기 용접식 또는 끼워넣기 용접식 등의 결합방식이 이용된다. 또한, 두께가 얇은 관에는 통상 끼워넣기 용접식 또는 끼워넣기 납땜식 등의 결합방식을 이용한다.As a coupling method of a pipe and a flange, coupling methods, such as screw threading, butt welding or an insert welding type, are used generally. In addition, a coupling method such as an insert welding method or an insert soldering method is usually used for a thin tube.
파이프 등을 연결하기 위한 플랜지의 종래기술은 하기와 같다.The prior art of the flange for connecting a pipe or the like is as follows.
한국공개특허 제2010-0109022호에서는 도 1에 나타난 바와 같이 중공과 그 외측의 다수의 체결홀을 구비하는 판상의 플랜지; 상기 플랜지가 회전가능하도록 플랜지의 중공에 삽입되는 제1 직경부와 배관과 연결되는 제2 직경부를 구비하는 체결구 및 상기 체결구의 제1 직경부 단부에 결합되어 상기 플랜지가 상기 제1 직경부로부터 이탈하는 것을 방지하는 고정판을 포함하는 것을 특징으로 하는 배관 연결용 플랜지 조립체에 관하여 개시하고 있다.Korean Patent Laid-Open No. 2010-0109022 discloses a plate-like flange having a plurality of fastening holes on the outside and a hollow as shown in FIG. 1; A fastener having a first diameter portion inserted into the hollow of the flange and a second diameter portion connected to the pipe so that the flange is rotatable, and coupled to an end portion of the first diameter portion of the fastener so that the flange is separated from the first diameter portion. Disclosed is a flange assembly for pipe connection, characterized in that it comprises a fixing plate to prevent it from slipping off.
한국공개특허 제2008-0060212호에서는 도 2에 나타난 바와 같이 파이프 간에 연결되어 유체의 분기나 방향 전환에 사용되는 파이프 연결구에 있어서, 내부 유로를 갖는 몸체부, 상기 몸체부의 단부에 마련되며 외측 영역에 복수의 볼트 체결홀이 형성된 플랜지부를 포함하는 플랜지형 파이프 연결구에 관하여 개시하고 있다.In Korean Patent Laid-Open No. 2008-0060212, as shown in FIG. 2, in a pipe connector connected between pipes and used for diverging or redirecting a fluid, a body portion having an inner flow path and an end portion of the body portion are provided at an outer region. Disclosed is a flanged pipe connector including a flange portion having a plurality of bolted fastening holes.
상기 종래기술에서 개시한 파이프 연결용 플랜지들은 플랜지의 몸체에 볼트삽통 체결홀이 형성되어 환상의 외주부가 마련되므로 플랜지의 직경이 커지고 이에 비례하여 두께도 증가되어 파이프 내 유체의 양과 압력에 비해 필요 이상으로 플랜지 몸체가 커져 중량이 증가되고 자재비가 상승되는 문제점이 있다.The flanges for pipe connection disclosed in the prior art have a bolt insertion hole formed in the body of the flange to provide an annular outer circumference, so that the diameter of the flange is increased and the thickness thereof increases in proportion to the amount and pressure of the fluid in the pipe. As a result, there is a problem that the weight of the flange body increases and the material cost increases.
종래기술에서 개시한 플랜지를 체결하기 위해서는 양쪽 플랜지의 볼트 체결홀을 정확하게 맞추어 시공해야 하므로 체결홀을 맞추기 위한 시간이 많이 소요되며, 실제 작업시 양쪽 플랜지에 볼트삽통 체결홀을 맞추는 과정에서 공차를 벗어난 상태가 빈번하게 발생되어 수정 작업을 위해 파이프의 플랜지 이음 용접된 부위를 절단하여 볼트 체결홀을 정확하게 맞춘 후 다시 용접해야 하는 이중 작업이 빈번하게 발생된다.In order to fasten the flanges disclosed in the prior art, it is necessary to accurately fit the bolt fastening holes of both flanges, so it takes a lot of time to fit the fastening holes. The condition frequently occurs, and the duplex operation frequently occurs in which the flange joint welded portion of the pipe is cut to correct the bolt fastening hole and then welded again for corrective work.
또한, 종래기술에서 개시한 플랜지에 일체형으로 형성된 볼트 체결홀에 볼트를 삽입해야 하기 때문에 작업을 위한 공간범위가 한정되어 작업자가 볼트 체결시 작업 자세가 불안전하고 플랜지 체결 시간이 많이 소요되며, 필요 이하의 저압인 경우에도 몸체의 볼트 체결홀에 볼트를 전부 체결해야 하는 문제점이 있다.In addition, since the bolt must be inserted into the bolt fastening hole formed integrally to the flange disclosed in the prior art, the space range for the work is limited, so that the worker's posture is unstable when the bolt is fastened and the flange fastening time is required. Even in the case of low pressure, there is a problem that all the bolts should be fastened to the bolt fastening holes of the body.
본 발명자들은 상술한 종래의 관이음용 플랜지의 문제점을 해결하여 플랜지의 크기를 작게 하고 모양을 단순화하게 하여 제조비용을 감소시키며 플랜지의 체결시 작업이 용이하며 체결력 또한 우수한 파이프 연결용 플랜지를 개발하여 본 발명을 완성하기에 이르렀다.The present inventors have solved the above problems of the conventional flange for pipe joints to reduce the size of the flange and simplify the shape to reduce the manufacturing cost and to develop a flange for pipe connection that is easy to work when the flange is fastened and also excellent fastening force The present invention has been completed.

In the present invention, the plurality of clip hooks may be coupled at regular intervals to the hypotenuse protrusions formed on the outer surface of the flange in consideration of the number of clip hooks determined by calculating the internal pressure and the bolting compression force of the flange.
상기 너트는 클립훅과 접촉면이 라운드 형태로 제조된 것을 사용하여 본 발명에 따른 관 이음용 플랜지 조립체의 체결력을 향상시킬 수 있다.The nut may improve the fastening force of the flange assembly for pipe fittings according to the present invention by using a clip hook and the contact surface is manufactured in a round shape.
