Description

가스 주름관 연결장치{The Fitting For Gas Flexible Hose}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a gas-

본 발명은 가스 주름관 연결장치에 관한 것으로서, 더욱 상세하게는 가스 이동형 주름관을 연결장치를 통해 상호 연결할 때 나사 체결에 의해 주름관이 소성 변형되면서 압착되어 기밀성을 향상시킬 수 있도록 하는 가스 주름관 연결장치에 관한 것이다.
The present invention relates to a gas corrugated pipe connecting apparatus, and more particularly, to a gas corrugated pipe connecting apparatus which is capable of compressing a corrugated pipe by screwing to compress airtightness when the gas moving corrugated pipes are interconnected through a connecting device will be.

종래에는 주름관을 연결할 때 누수를 방지하기 위하여 나사부가 형성된 연결구 본체의 내부에 단턱부와 경사부를 형성하고, 단턱부에는 경사부가 형성된 고무패킹을 주름관을 삽입 체결하되 주름관의 외부에는 경사부가 형성된 고무패킹을 체결하고 고무패킹의 일측에서 고정구와 너트로서 고무패킹을 압축하여 누수를 방지하였다.In the prior art, a stepped portion and an inclined portion are formed inside a connecting body having a threaded portion for preventing water leakage when connecting a corrugated pipe, and a corrugated tube is inserted into a rubber packing having an inclined portion formed in a stepped portion, And the rubber packing was compressed as a fixture and a nut at one side of the rubber packing to prevent leakage.

상기의 방법은 단순히 고무패킹을 압박하여 누수를 방지하는 구성으로 미세한 진동으로 인하여 너트가 쉽게 풀리는 단점이 있었고, 너트가 풀어질 경우에는 패킹의 압축력이 약해지기 때문에 누수를 방지하지 못한 단점이 있었다.The above method has a disadvantage in that the nut is easily loosened due to the minute vibration by simply pressing the rubber packing to prevent leaking, and when the nut is loosened, the compressing force of the packing is weakened.

한편, 최근에는 누수를 방지하기 위하여 상기의 연결구에 체결되어 있는 고무패킹의 내경에 원형의 돌출부를 형성하여 주름관의 굴곡부에 체결되어 누수를 방지하도록 안출하였으나, 상기의 고안은 고무패킹의 돌출부에 의하여 고무패킹과 주름관 사이의 누수방지 효과를 최대로 하였으나, 진동으로 인하여 본체에서 너트가 자주 풀리는 근본적인 단점과 경사부가 형성된 고무패킹의 본체의 경사부에 체결되어 있기 때문에 너트가 약간만 풀리면 물이 흘러내리는 문제점이 있었다.Meanwhile, in recent years, in order to prevent water leakage, a circular protrusion is formed on the inner diameter of the rubber packing fastened to the connecting port to prevent leakage of water by being bent at the bent portion of the corrugated pipe. However, Although the effect of preventing the leakage between the rubber packing and the corrugated tube is maximized, the fundamental drawback that the nut is loosened frequently due to the vibration, and the water is drained when the nut is slightly loosened because the inclined portion is fastened to the inclined portion of the body of the rubber packing. .

또한, 상기의 고무패킹은 외부에 돌출부를 형성하기 위해서 일반적인 패킹과 다른 형태의 가공공정을 거쳐 제작되어야 함으로써, 제작단가가 상승되는 문제점이 있었다.In addition, since the rubber packing has to be manufactured through a process different from a general packing in order to form a protrusion on the outside, there is a problem that the manufacturing cost is increased.

아울러, 돌출부가 형성된 고무패킹은 외부에 불규칙한 돌출물에 형성으로 인하여 연결구에 체결이 어렵고, 쉽게 체결하기 위해서 돌출물의 돌출 크기를 감소시키면 누수의 원인되어 생산성을 저하시키는 문제점이 있었다.
In addition, since the rubber packing having the protruded portion is formed on the irregular protrusion on the outside, it is difficult to fasten the connecting portion to the connecting port, and if the protruding size of the protruding portion is reduced for easy fastening, leakage occurs and productivity is lowered.

따라서, 본 발명의 주 목적은 가스 이동형 주름관을 연결장치를 통해 상호 연결할 때 나사 체결에 의해 주름관이 소성 변형되면서 압착되어 기밀성을 향상시킬 수 있도록 하는 데 있다.

먼저, 본 발명의 가스 주름관 연결장치 100는 주름관 110, 밀착구 120, 압박구 130, 연결구 140로 구성된다.First, the gas pipe connecting apparatus 100 of the present invention comprises a corrugated pipe 110, a fitting 120, a compression fitting 130, and a connecting pipe 140.

상기 주름관 110은 스테인리스 재질로 이루어져 내식성이 높고 반영구적 사용이 가능하다.The corrugated pipe 110 is made of stainless steel and has high corrosion resistance and can be used semi-permanently.

특히, 주름관 110은 산과 골이 독립된 환상형의 주름을 연속적으로 형성하여 고신축이 가능하여 동파의 위험성이 적고 내충격성이 뛰어나다.Particularly, the corrugated pipe 110 forms annular-shaped wrinkles which are independent of the mountains and the valleys continuously to enable high expansion and contraction, so that the risk of freezing is low and the impact resistance is excellent.

이렇게, 주름 형상으로 성형되어 타강관 보다 내압이 크며, 소재 변형 및 파괴 등으로 인한 하자의 위험성이 낮다.In this way, the inner pressure is larger than that of the other steel pipes formed in a wrinkled shape, and the risk of defects due to material deformation and breakage is low.

또한, 별도의 공구나 전문 지식이 없어도 연결 부위로 인한 누수의 위험이 없다.In addition, there is no risk of leakage due to the joints even without separate tools or expertise.

상기 밀착구 120는 상기 주름관 110 일단 외주연에 결합되고 한 쌍으로 이루어진다.The contactor 120 is coupled to the outer circumferential edge of the one end of the corrugated tube 110 and is formed as a pair.

즉, 상기 밀착구 120는 반 호 형상을 갖는 조합편 121이 한 쌍으로 마련되고, 상기 조합편 121 내주연 일단에는 걸림부 122가 돌출되게 형성되어 주름관 110 외주연에 형성된 굴곡에 걸림부 122가 결합 될 수 있도록 한다.In other words, the close fitting part 120 is provided with a pair of combination pieces 121 having a half-arc shape, and a coupling part 122 is formed to protrude from one end of the periphery of the combination piece 121, .

여기서, 상기 밀착구 120의 조합편 121은 걸림부 122의 전방에 받침턱 123을 돌출되게 형성하여 압박구 130에 의해 리드 이동하면서 연결구 140의 유입홈 146에 결합되도록 한다.Here, the combination piece 121 of the fitting 120 has a protruding protrusion 123 protruded in front of the protrusion 122, and is connected to the inflow groove 146 of the connection port 140 while being lead-moved by the pushing part 130.

아울러, 압박구 130는 상기 주름관 110이 관통되면서 밀착구 120 외주연에 결합되도록 내주연에 암나사공 131이 형성된다.In addition, the pushing portion 130 is formed with a female screw hole 131 at its inner circumference so as to be coupled to the outer periphery of the fitting portion 120 while passing through the bellows pipe 110.

통상적으로 압박구 130는 너트 방식을 갖고, 상기 암나사공 131 내부에 밀착구 120가 결합하되, 상기 암나사공 131과 연통되고 지름이 작은 구멍과의 단차에 의해 밀착구 120가 암나사공 131 내부에 걸림 상태를 유지한다.The pushing portion 130 has a nut system. The pushing portion 120 is engaged with the inside of the female screw hole 131, and the step of the small-diameter hole communicating with the female screw hole 131 causes the fitting portion 120 to be caught in the female screw hole 131 State.

그리고, 상기 연결구 140는 일측에 마련된 제1결합부 141의 외주연에 숫나사 144를 형성하고 상기 제1결합부 141 내주연에 결합공 145을 형성하여 상기 압박구 130의 암나사공 131과 체결에 의해 밀착구 120가 결합공 145 내주연에서 리드 이동하면 상기 주름관 110의 일단이 결합공 145 내주연 단부에 형성된 유입홈 146으로 진입하여 접철되면서 결합되도록 한다.A male screw 144 is formed on the outer periphery of the first engaging part 141 provided on one side of the connector 140, and a coupling hole 145 is formed on the periphery of the first engaging part 141. By fastening the female screw 144 to the female screw 131 of the pushing part 130 When the contact hole 120 is lead-moved at the periphery of the engaging hole 145, one end of the corrugated pipe 110 enters the inflow groove 146 formed at the peripheral end of the engaging hole 145 and is folded and joined.

상기 연결구 140의 구체적은 구성은 외주연이 다각형으로 형성된 본체 143와, 상기 본체 143 일측과 타측에 형성되어 외주연에 숫나사 144가 형성되고 내부에 결합공 145을 형성한 제1결합부 141 및 제2결합부 142로 구성하되, 상기 제1결합부 141의 결합공 145 내주연 단부에는 경사진 유입홈 146이 형성한다.The connector 140 includes a main body 143 having a polygonal outer periphery, a first engaging portion 141 formed at one side and the other side of the main body 143 and having a male screw 144 formed on the outer periphery thereof, 2 engaging portion 142, and an inclined inflow groove 146 is formed in a peripheral end portion of the engaging hole 145 of the first engaging portion 141.

상기와 같이 구성되는 가스 주름관 110 연결장치의 작동은 아래와 같다.Operation of the connecting device of the gas corrugated pipe 110 constituted as described above is as follows.

상기 압박구 130의 암나사공 131에 주름관 110 관통되게 결합하되, 상기 압박구 130는 주름관 110의 일단 근처에 위치시킨다.The pushing member 130 is coupled to the female screw hole 131 of the pushing member 130 so that the pushing member 130 is positioned near one end of the corrugated pipe 110.

여기서, 한 쌍의 밀착구 120는 주름관 110의 일단 외주연에 결합하여 상기 밀착구 120가 상기 압박구 130의 암나사공 131 내부에 위치시킨다.Here, the pair of fittings 120 are engaged with the outer periphery of one end of the bellows pipe 110, and the fitting 120 is positioned inside the female screw hole 131 of the pressing part 130.

이때, 상기 암나사공 131과 연통되고 지름이 작은 구멍과의 단차에 의해 밀착구 120가 암나사공 131 내부에 결합 상태가 유지된다.At this time, the fastener 120 is held in the inside of the female screw hole 131 by a step between the female screw hole 131 and the small diameter hole.

여기서, 상기 밀착구 120는 반 호 형상을 갖는 조합편 121이 한 쌍으로 마련되고, 상기 조합편 121 내주연 일단에는 걸림부 122가 돌출되게 형성되어 주름관 110 외주연에 형성된 굴곡에 걸림부 122가 결합될 수 있다.The fastener 120 is provided with a pair of comb-pieces 121 having a half-arc shape, and a fastening part 122 is formed at one end of the periphery of the comb-piece 121 so as to protrude therefrom. Can be combined.

이후, 상기 연결구 140를 압박구 130의 암나사공 131에 나사 체결하여 리드 이동함에 따라 연결구 140 내부의 결합공 145을 갖는 제1결합부 141 내부로 주름관 110과 밀착구 120가 연동하여 진입한다.Then, as the coupling 140 is screwed into the female screw hole 131 of the pushing part 130, the corrugated pipe 110 and the fitting part 120 interlock with each other into the first coupling part 141 having the coupling hole 145 in the coupling hole 140 as the lead moves.

이때 두께가 얇고 재질이 경질인 주름관 110의 일단이 제1결합부 141의 결합공 145 다누에 형성된 경사진 유입홈 146측으로 진입되면서 소성 변형이 일어난다.At this time, one end of the bellows pipe 110 having a thin thickness and a hard material enters the inclined inflow groove 146 formed in the engagement hole 145 of the first engagement portion 141, and plastic deformation occurs.

나사체결에 의해 연결구 140와 압박구 130가 상호 밀착되게 이동하는 과정에서 상기 주름관 110 일단이 유입홈 146으로 진입하여 소성 변형되면서 주름관 110 일단이 접철된다.As the connecting hole 140 and the pushing member 130 are moved in close contact with each other by screwing, the one end of the bending pipe 110 enters the inflow groove 146 and is plastically deformed, so that one end of the bending pipe 110 is folded.

이렇게 상기 연결구 140와 압박구 130의 나사체결에 의해 밀착구 120를 통해 주름관 110이 리드 이동하여 상기 주름관 110 일단이 연결구 140의 내부로 진입하여 접철되면서 주름관 110 외주연에 밀착구 120와 연결구 140 사이에 압착되어 주름관 110의 연결을 가능하게 하면서 기밀성을 유지할 수 있다.As a result, the corrugated pipe 110 is led through the contact hole 120 by the screwing of the connecting hole 140 and the pushing hole 130, so that the one end of the corrugated pipe 110 enters the inside of the connecting hole 140 and is folded, So that the airtightness can be maintained while allowing the connection of the corrugated pipe 110.
