본 고안은 주로 산업용 대형펌프나 저유냉크등의 배관시에있어 진동을 방지하고 지반침하등에 대한 대책용으로 쓸수 있게 한 방진용 신축이음구에 관한 것이다.The present invention mainly relates to a dustproof expansion joint that can be used for preventing vibration and preventing ground subsidence in piping of large industrial pumps or low oil chillers.
종래에는 통상 신축성이 없는 플랜지를 이용한 관이음을 하므로서 축방향으로나 축에 직각방향으로 온도차나 기타의 원인으로 인한 변화가 주어질 경우에 플랜지로 관이음을 한 부분이 느슨해져서 유체가 누출되어 산업재해의 원인이 되었고, 심한 경우에는 플랜지가 균열되어 파손되므로서 막대한 재산상의 피해를 입는 경우가 있었다.Conventionally, pipe joints using non-elastic flanges are used in the axial direction or at right angles to the shaft, so when the change due to temperature difference or other causes is caused, the pipe joint is loosened by the flange and fluid leaks. In severe cases, the flanges cracked and damaged, resulting in massive property damage.
이러한 실정을 감안한 업계에서는 자유로운 벨로우즈를 이용한 배관방법을 개발하여 사용해 왔었다.In consideration of this situation, the industry has developed and used a piping method using free bellows.
그러나 벨로우즈 자체는 신축성이 양호한 반면 충격에 대한 흡수성이 없어 벨로우즈 외부로 첨부도면 제3도에서 표현한 바와 같이 보강재인 브레이드(51)를 이용하여 견고성 있게 배관을 한바, 이는 신축범위가 제한적이었고 관에 접속시키는 방법도 복잡하여 고가를 요구하게 되었으여 신축의 용량 제한에 의해 벨로우즈의 길이와 브레이드(51)가 길어져야만 되는 결과로 고가의 제작비가 소요되는 협소한 공간에서는 사용될 수 없었다.However, the bellows itself has good elasticity, but it does not absorb shock, so that the bellows is firmly piped using the braid 51, which is a reinforcing material, as shown in FIG. 3 attached to the outside of the bellows. As a result of the complicated method, it was required to be expensive, and as a result, the length of the bellows and the braid 51 had to be lengthened due to the capacity limitation of the expansion and contraction.
또 일본국에서 벨로우즈가 플랜지에 고정부착된 신축이음구 몇개를 연결간으로 플랜지를 관통하여 상호연결한 것을 관이음에 사용하는 단일평형 신축관 접수(실개소49-75116호)가 1974년 공개된 바 있으나 플랜지가 단순히 연결관으로 연결되어 너트로 고정되어있으므로 관이음부에 지속적으로 생기는 진동이나 충격을 효율적으로 흡수하지 못하는 결점이 있었다.Also, in 1974, a single flat expansion pipe acceptor (opening number 49-75116) was used in Japan, where bellows were connected to each other through a flange between several expansion joints fixed to the flange. However, since the flange is simply connected with a connection pipe and fixed with a nut, there is a defect in that it does not efficiently absorb the vibration or shock generated continuously in the pipe joint.
본 고안은 이러한 문제점을 해소하고자 안출된 것으로서 이를 첨부된 도면에 의하여 상세히 설명하면 다응과 같다.The present invention has been devised to solve such a problem and will be described in detail with reference to the accompanying drawings.
플랜지(2)(2')의 중심구멍(4)(4')에 벨로우즈(1)가 고정부착되고 플랜지(2)(2')가 볼트(3)로서 관이음되는 통상의 방진용 신축 이음구에 있어서, 상기 플랜지(2)(2')의 외측면 주요개소에 완충제 삽입홈(5')을 갖는 유동구멍(5)을 각각 형성하고 완충재(6)를 유동구멍(5)에 삽입하여 상기 볼트(3)로 체결한 것으로서 도면중 미설명 부호 A는 상기 체결볼트(3)에 나사맞춤되는 너트, B는 체결핀, C는 배관코자 하는 관을 이을때 사용되는고정구멍, D는 분할핀을 표시한다.Conventional anti-vibration expansion joint with bellows 1 fixedly attached to the center hole 4 and 4 'of the flange 2 and 2' and the flange 2 and 2 'to be piped as bolts 3 In the main surface of the outer surface of the flange (2) (2 '), each of the flow holes (5) having a buffer inserting groove (5') and inserting the buffer material (6) into the flow hole (5) In the figure, reference numeral A denotes a nut that is screwed to the fastening bolt 3, B denotes a fastening pin, C denotes a fixing hole used to connect a pipe to be piped, and D denotes a split pin. Display.
이와 같은 구조로된 본 고안은 첨부도면 제2도에서 가상선으로 표현한 바와 같이 본 고안은 플랜지(2)(2')에 형성된 고정구멍(C)을 이용하여 접속하고자 하는 각종 관등을 플랜지(2)(2')에 체결한 상태에서 두관이 펌프의 진동이나 외부충격으로 인해 축선상의 어긋남이 발생하게 되면 일측 플랜지(2)와 타측 플랜지(2')가 어긋나게 되는데, 이때 체결볼트(3)는 완충재(6)를 사이에 두고 너트(A)와 나사맞춤이 되어 있으므로 진동을 충분히 흡수할 수 있어 균열로 인한 누수현상등을 미연에 방지하는 것이다.As the present invention having such a structure is represented by a virtual line in the accompanying drawings, Figure 2, the present invention is a flange (2) for connecting various pipes to be connected by using a fixing hole (C) formed in the flange (2) (2 '). (2 ') when the two pipes are axially displaced due to vibration or external shock of the pump, one flange (2) and the other flange (2') are displaced. At this time, the fastening bolt (3) Since the shock absorbing material 6 is interposed between the nut A and the nut A, the vibration can be sufficiently absorbed to prevent leakage due to cracking.
그리고 첨부도면 제4도에서 표현한 바와 같이 분할핀(D)으로 너트를 고정한것은 진동으로 인하여 체결볼트(3)가 이완되므로서 벨로우즈(1)에 무리가 가는 것을 방지고자 한 것이다.And fixing the nut with the split pin (D) as shown in Figure 4 is intended to prevent the going to the bellows (1) as the fastening bolt (3) is relaxed due to vibration.
상술한 바와 같은 본 고안은 브레이드(51)를 이용하지 않고 플랜지(2)(2')의 형상에 적합한 다수개의 체결볼트(3)로서 보강 설치시겼으므로 그 이음 결착상태가 견고함과 동시에 협소한 공간에서도 충분한 이음 효과를 얻을 수 있는 유용한 고안인 것이다.As described above, the present invention has been reinforced and installed as a plurality of fastening bolts 3 suitable for the shape of the flanges 2, 2 'without using the braid 51. It is a useful design that can achieve a sufficient joint effect in one space.
