본 발명은 주로 유체이송관에 연결설치되어 이송관의 과중한 응력을 흡수하는 익스팬션죠인트의 벨로우즈 보강용 콘트롤 링에 관한 것이다.The present invention mainly relates to a bellows reinforcement control ring of an expansion joint that is connected to a fluid transfer pipe and absorbs excessive stress of the delivery pipe.

주로 가스나 원유 그리고 스팀 등을 이송하는 배관시스템의 이송관들은 외부 온도나 유체의 온도변화에 의한 배관의 팽창과 수축 그리고 기기의 진동과 풍압 및 지진 등에 의해 이송관에 가해지는 과중한 응력을 흡수하여 배관시스템을 유지하도록 하는 익스팬션죠인트가 연결설치된다.The conveying pipes of the piping system that mainly transport gas, crude oil and steam absorb the excessive stress applied to the conveying pipe by expansion and contraction of the pipe due to the change of external temperature or fluid temperature and vibration, wind pressure and earthquake of the equipment. Expansion joints are installed to maintain the piping system.

이때 이용되는 익스팬션죠인트는 거의 대부분 응력흡수가 용이한 벨로우즈(Bellows)를 갖도록 한 것으로서, 요구되는 기본적인 기능은 충분히 만족할 수가 있으나 벨로우즈가 갖는 특성상 원활한 신축작용을 위하여는 두께가 얇은 소재를 이용하여야 하므로 이러한 기본적인 기능을 만족시켜줄수록 이송관의 사용압력과 설계압력에 견딜 수 있는 강성은 상대적으로 약화될 수밖에 없게 된다.At this time, the expansion joints are almost always designed to have a bellows that can easily absorb stress, and the basic function required can be satisfactorily satisfied. However, a thin material must be used for smooth stretching due to the characteristics of the bellows. As the basic function is satisfied, the rigidity that can withstand the operating pressure and the design pressure of the transfer pipe is inevitably weakened.

즉 익스팬션죠인트가 갖는 벨로우즈는 박판의 스테인레스 스틸로 성형제작되는 것으로서, 파이프의 내부압력이 증가할수록 소재의 두께를 증가시켜주어야만 압력에 견딜 수 있는 충분한 강도를 지니게 되나 소재의 두께가 두꺼워질수록 벨로우즈의 유연성이 저하되어 원활한 기능을 발휘할 수가 없게 되고 또 이송관의 변위를 흡수할 시 피로도가 심해 크랙발생 등에 의한 사용수명단축을 가져오게 된다.In other words, the bellows of expansion joint is made of thin stainless steel, and as the internal pressure of the pipe increases, the thickness of the material must be increased to have sufficient strength to withstand the pressure, but the thicker the material, Due to the reduced flexibility, the smooth function cannot be exhibited and the fatigue is too high when absorbing the displacement of the feed pipe, resulting in shortened service life due to cracking.

따라서 종래에도 도 4 및 도 5에서와 같이 벨로우즈의 소재 두께를 얇게 하여 충분한 유연성을 갖도록 하면서 벨로우즈가 갖는 각 골에 콘트롤 링(50)을 결합하여 볼트와 너트를 이용한 죄임으로 고정하여 충분한 보강력을 얻도록 하고 있다.Therefore, in the related art, as shown in FIGS. 4 and 5, the material thickness of the bellows is made thin enough to have sufficient flexibility, and the control ring 50 is coupled to each valley of the bellows to fix the clamping force using a bolt and a nut to provide sufficient reinforcement. I'm getting.

그러나 이러한 구조의 콘트롤 링(50)은 링본체(52) 외에 결합공(54a)(56a)이 천공되는 홀더(54)(56)와 상기 홀더가 벨로우즈(58)로부터 돌출되게 하여 죄임이 용이하도록 하는 리브(60)(62) 및 볼트(64)와 너트(66)를 필요로 하는 복잡한 구조로서 부품의 구입 및 가공경비가 많이 소요되고 또 복잡한 제조공정으로 생산성 저 하를 가져오게 되며 조립 고정시에는 홀더(54)(56)가 갖는 결합공(54a)(56a)에 볼트(64)를 관통시켜서 너트(66)의 수회 회전으로 죄여주는데 시간이 많이 소요되고 이러한 볼트넛의 죄임을 위하여 홀더(54)(56)가 벨로우즈(58)로부터 돌출되므로 취급시 돌출된 홀더(54)(56)와 볼트넛(64)(66)에 의해 다른 부품의 손상우려가 있고 또 파이프에 연결사용시 그 주위를 지나다니는 작업자들의 안전사고를 유발시킬 우려가 있게 되는 등의 많은 문제점들이 있는 것이다.However, the control ring 50 of this structure has a holder 54 and 56 in which the coupling holes 54a and 56a are drilled in addition to the ring body 52 and the holder protrudes from the bellows 58 so as to facilitate tightening. It is a complicated structure that requires ribs 60, 62, bolts 64, and nuts 66, which requires a lot of parts purchase and processing costs, and brings productivity down to complicated manufacturing processes. In order to penetrate the bolt 64 through the coupling holes 54a and 56a of the holders 54 and 56, it takes a long time to tighten the nut 66 several times. (54) (56) protrudes from the bellows (58), so the holders (54) and (56) and boltnuts (64) and (66) protrude during handling, which may damage other parts, and when connected to pipes, There are many problems such as the possibility of causing a safety accident for workers passing by. A.

본 발명은 상술한 종래기술이 갖는 문제점들을 감안하여 필요로 하는 부품수와 제조공정을 줄일 수가 있어 부품의 구입 및 가공경비를 줄일 수가 있고 또 간단한 제조공정으로 생산성 향상을 가져올 수가 있으며, 벨로우즈에 보다 신속하게 고정설치해줄 수가 있고 부품이 일부나마 벨로우즈 외측으로 돌출될 우려가 없어 취급이 용이할 뿐 아니라 주위를 지나다니는 작업자들의 안전사고 우려를 없애줄 수가 있는 익스팬션죠인트의 벨로우즈 보강용 콘트롤링을 제공하고자 한다.The present invention can reduce the number of parts and the manufacturing process required in view of the problems of the prior art described above, can reduce the purchase and processing cost of parts, and can bring productivity improvement with a simple manufacturing process, It is intended to provide bellows reinforcement control of expansion joints that can be fixed and installed quickly, and there is no risk of parts protruding outward from the bellows, which is easy to handle and eliminates the safety accidents of workers passing by. .

상기한 본 발명의 목적은 벨로우즈에 결합시 링본체의 외측단부에 용접형성되는 연결편이 서로 교차하도록 하여 그 교차부위의 용접으로 고정되게 한 콘트롤 링에 의해 달성된다.The object of the present invention described above is achieved by a control ring which allows the connecting pieces which are welded to the outer end of the ring body to intersect with each other so as to be fixed by welding at their intersections when they are coupled to the bellows.

도 1은 본 발명의 사시도로서, 본 발명은 일측이 절단되어 마주하는 양단부를 갖는 링본체(2)와, 상기 링본체(2)의 외측 양단부에 일부가 돌출되도록 용접형성되는 연결편(4)(6)으로 구성된다.1 is a perspective view of the present invention, the present invention is a ring body (2) having one end is cut and facing each other, and a connecting piece (4) welded so as to project a part of the outer both ends of the ring body (2) ( 6).

상기 링본체(2)는 단면 원형으로 이루어지나 반원형이나 각 형 등 단면 형태에 관계없이 이용가능하며 금속봉체를 벤딩형성하거나 또는 원형으로 제작된 링의 일측을 절단하여 사용하더라도 무방하다.The ring body (2) is made of a circular cross section, but can be used regardless of the cross-sectional shape, such as semi-circular or angular, and may be used by bending a metal rod or cutting one side of the ring made in a circular shape.

또한 링본체(2)의 양단부에 용접형성되는 연결편(4)(6)은 비교적 납작하고 긴 형태로서 각각 링본체(2)의 외측단부에 그 중심선으로부터 서로 상반된 방향으로 치우치게 용접형성하여 그 용접부로부터 돌출되는 돌출부가 긴밀한 접촉상태로 교차하도록 구성된다.In addition, the connecting pieces 4 and 6 welded to both ends of the ring body 2 are relatively flat and long in shape, and are welded to the outer end of the ring body 2 in a direction opposite to each other from the center line thereof, respectively. The protruding protrusions are configured to intersect in intimate contact.

본 발명 콘트롤 링(A)은 링본체(2)를 충분히 벌려서 벨로우즈(8)가 갖는 골(10)에 끼운 다음 최대한 오무려서 양단부가 마주하도록 하게 되면 좌우 연결편(4)(6)이 갖는 돌출부는 그 측면이 긴밀한 접촉상태로 마주하게 되므로 작업자가 좌우 연결편(4)(6)을 용접이음 해주는 것으로 서로 일체감있게 연결되어 벨로우즈(8)를 보강하는 콘트롤링(A)으로서의 기능을 발휘하게 된다.When the control ring (A) of the present invention is wide enough to open the ring body (2) to be inserted into the valley (10) of the bellows (8), and then as much as possible so that both ends face each other, the protrusions of the left and right connecting pieces (4) (6) Since the side faces in intimate contact state, the operator is jointly connected to each other by welding the left and right connecting pieces (4) and (6) to exert a function as a control ring (A) to reinforce the bellows (8).

또한 이러한 좌우연결편(4)(6)의 용접시에는 용접기가 진입할 수 있는 약간의 공간만 확보해 주면 되므로 벨로우즈(8)가 갖는 골(10)을 통하여 충분한 용접이 이루어질 수가 있게 됨은 물론 콘트롤링(A)은 벨로우즈(8) 외측으로 돌출될 우려가 전혀 없어 취급이 용이하고 또 안전사고 우려를 없애줄 수가 있으며, 링본체(2)는 좌우연결편(4)(6)에 의한 용접이음으로 사용중 외부로부터의 충격에도 벌어지거나 파손될 우려가 없어 벨로우즈(8)의 수명이 다할때까지 제기능을 다할 수 있게 되는 것이다.In addition, when welding the left and right connecting pieces (4) and (6) only need to secure a little space for the welder can enter, sufficient welding can be made through the valley 10 of the bellows (8), as well as the control ring (A) has no fear of protruding outward from the bellows (8), so it is easy to handle and can eliminate safety accidents.The ring body (2) is welded by the left and right connecting pieces (4) (6). There is no risk of opening or breaking even from the impact from the bellows (8) will be able to function until the end of the life of the bellows (8).

이와 같이 본 발명은 제작시 줄어든 부품수와 제조공정만큼 생산성 향상을 가져올 수가 있고 또 링본체(2)의 양단부에 갖는 연결편(4)(6)을 통하여 용접고정해주면 되므로 설치가 용이하며, 설치시 벨로우즈(8) 외측으로 일부나마 돌출될 우려가 전혀없어 외관이 미려할 뿐 아니라 주위를 지나다니는 작업자들의 안전사고 우려를 없애줄 수가 있게 되는 등의 효과가 있는 것이다.As described above, the present invention can bring about improved productivity as the number of parts and manufacturing process reduced during manufacturing, and the welding is fixed through the connecting pieces 4 and 6 provided at both ends of the ring body 2. There is no fear of protruding to some extent outside the bellows (8), the appearance is not only beautiful but also has the effect of being able to eliminate the safety accidents of workers walking around.
