Description

가스 주름관 연결장치{The Fitting For Gas Flexible Hose}Gas corrugated pipe connection device {The Fitting For Gas Flexible Hose}

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 device, and more particularly, to a gas corrugated pipe connecting device that can improve the airtightness by compressing the corrugated pipe plastically by screwing when the gas movable corrugated pipe is interconnected through the 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.Conventionally, in order to prevent leakage when connecting a corrugated pipe, a stepped portion and an inclined portion are formed inside the body of the connector formed with a threaded portion, and a rubber packing formed with an inclined portion is inserted into the stepped portion to insert a corrugated pipe, but a rubber packing formed with an inclined portion outside the corrugated pipe And tightened the rubber packing as a fixture and a nut on 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 a minute vibration due to a configuration that simply prevents leakage by compressing the rubber packing, and when the nut is loosened, there is a disadvantage in that the leakage is not prevented because the compressive 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.On the other hand, recently, in order to prevent water leakage, a circular protrusion was formed on the inner diameter of the rubber packing fastened to the connector, so that it was fastened to the bent part of the corrugated pipe to prevent leakage, but the above-mentioned design was made by the protrusion of the rubber packing. The effect of preventing leakage between the rubber packing and the corrugated pipe was maximized, but the fundamental disadvantage of the nut being frequently loosened from the body due to vibration and the problem of water flowing out when the nut is loosened slightly because it is fastened to the inclined part of the rubber packing formed with the inclined part There was.

또한, 상기의 고무패킹은 외부에 돌출부를 형성하기 위해서 일반적인 패킹과 다른 형태의 가공공정을 거쳐 제작되어야 함으로써, 제작단가가 상승되는 문제점이 있었다.In addition, the above rubber packing has to be manufactured through a general packing and other types of processing to form a protrusion on the outside, thereby increasing the manufacturing cost.

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, the rubber packing formed with the protrusions is difficult to fasten to the connector due to the formation of irregular protrusions on the outside, and reducing the protrusion size of the protrusions for easy fastening has a problem of decreasing productivity due to leakage.

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 corrugated pipe connection device 100 of the present invention is composed of a corrugated pipe 110, a close contact port 120, a compression port 130, a connection port 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.In particular, the corrugated pipe 110 is highly elastic by continuously forming an annular corrugation in which the mountains and valleys are independent, so there is little risk of freezing and excellent impact resistance.

이렇게, 주름 형상으로 성형되어 타강관 보다 내압이 크며, 소재 변형 및 파괴 등으로 인한 하자의 위험성이 낮다.In this way, it is molded into a corrugated shape, and has a higher internal pressure than a perforated pipe, and has a low risk of defects due to material deformation and destruction.

또한, 별도의 공구나 전문 지식이 없어도 연결 부위로 인한 누수의 위험이 없다.In addition, there is no risk of water leakage due to the connection site without the need for a separate tool or expertise.

상기 밀착구 120는 상기 주름관 110 일단 외주연에 결합되고 한 쌍으로 이루어진다.The close contact port 120 is coupled to the outer periphery of the corrugated pipe 110 and consists of 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.That is, in the close contact port 120, a combination piece 121 having a half arc shape is provided in a pair, and the engaging portion 122 is formed to protrude at one end of the inner edge of the combination piece 121, and the engaging portion 122 is formed in a bend formed on the outer circumference of the corrugated pipe 110. To be combined.

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 close contact port 120 is formed to protrude the support jaw 123 in front of the locking portion 122 to be coupled to the inflow groove 146 of the connector 140 while moving the lead by the compression port 130.

아울러, 압박구 130는 상기 주름관 110이 관통되면서 밀착구 120 외주연에 결합되도록 내주연에 암나사공 131이 형성된다.In addition, the compression hole 130 is formed with a female thread hole 131 on the inner periphery so as to be coupled to the outer peripheral periphery of the contact hole 120 as the corrugated pipe 110 passes.

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.Normally, the compression hole 130 has a nut method, and the contact hole 120 is coupled to the inside of the female thread hole 131, but the contact hole 120 is jammed inside the female thread hole 131 by a step difference between the female screw hole 131 and a small diameter hole. Maintain the 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.And, the connector 140 is formed by male screw 144 on the outer periphery of the first coupling portion 141 provided on one side, and by forming a coupling hole 145 on the inner periphery of the first coupling portion 141 by fastening with the female screw hole 131 of the pressing hole 130 When the contact port 120 leads from the inner periphery of the engaging hole 145, one end of the corrugated pipe 110 enters the inflow groove 146 formed at the inner peripheral edge of the engaging hole 145 so as to be folded and coupled.

즉, 상기 연결구 140의 구체적인 구성은 아래와 같다.
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.That is, the specific configuration of the connector 140 is as follows.
The outer periphery is composed of a main body 143 formed of a polygon, and the first coupling portion 141 and the second coupling portion 142 having male threads 144 formed on one side and the other side of the main body 143 and forming a coupling hole 145 therein, An inclined inflow groove 146 is formed at the inner peripheral edge of the coupling hole 145 of the first coupling portion 141.

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

상기 압박구 130의 암나사공 131에 주름관 110 관통되게 결합하되, 상기 압박구 130는 주름관 110의 일단 근처에 위치시킨다.The compression hole 130 is coupled to the female thread hole 131 to penetrate the corrugated pipe 110, and the pressure gauge 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 contact holes 120 are coupled to the outer periphery of one end of the corrugated pipe 110 so that the contact hole 120 is positioned inside the female thread hole 131 of the compression hole 130.

이때, 상기 암나사공 131과 연통되고 지름이 작은 구멍과의 단차에 의해 밀착구 120가 암나사공 131 내부에 결합 상태가 유지된다.At this time, the close contact port 120 is maintained inside the female screw hole 131 by a step difference 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.Here, in the close contact port 120, a combination piece 121 having a half arc shape is provided in a pair, and the engaging portion 122 is formed to protrude at one end of the inner edge of the combination piece 121, and the engaging portion 122 is formed in a bend formed on the outer circumference of the corrugated pipe 110. 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 lead 140 is screwed into the female thread hole 131 of the compression hole 130 and the lead moves, the corrugated pipe 110 and the contact hole 120 interlock into the first coupling portion 141 having the coupling hole 145 inside the connector 140.

이때 두께가 얇고 재질이 경질인 주름관 110의 일단이 제1결합부 141의 결합공 145 단부에 형성된 경사진 유입홈 146측으로 진입되면서 소성 변형이 일어난다.At this time, the plastic deformation occurs as one end of the thin and hard material corrugated pipe 110 enters the inclined inflow groove 146 formed at the end of the coupling hole 145 of the first coupling portion 141.

나사체결에 의해 연결구 140와 압박구 130가 상호 밀착되게 이동하는 과정에서 상기 주름관 110 일단이 유입홈 146으로 진입하여 소성 변형되면서 주름관 110 일단이 접철된다.In the process of connecting the connector 140 and the pressure tool 130 to be in close contact with each other by screwing, the one end of the corrugated pipe 110 enters the inflow groove 146 and is plastically deformed so that one end of the corrugated 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 described above, the corrugated pipe 110 leads through the contact port 120 by screwing the connector 140 and the compression port 130, and one end of the corrugated pipe 110 enters the inside of the connector 140 and folds, thereby causing the contact between the contact port 120 and the connector 140 to the outer periphery of the corrugated pipe 110. It can be compressed to maintain the airtightness while allowing the connection of the corrugated pipe 110.
