Abstract

The present invention relates to a liquefied-gas pipe coupling assembly, which seals the space between a coupling used when a pipe for liquefied gas having strong vaporability, including a refrigerant gas, is laid and a nipple connected to the pipe, so as to discharge remaining gas in one direction and, simultaneously, has a flange formed at the coupling, so as to protect the hands of a worker from the remaining gas left in the pipe during pipe dismantlement work. The present invention forms the liquefied-gas pipe coupling assembly having a snap ring coupling groove and an O-ring coupling groove formed on the outer peripheral surface of the front end of the nipple, having a snap ring coupling groove formed on the inner peripheral surface of the coupling, which is coupled to cover the outside of the nipple, so as to correspond to the snap ring coupling groove formed on the outer peripheral surface of the front end of the nipple, so that a snap ring is inserted therein and couples the nipple and the coupling in order to prevent the separation thereof, having an O-ring fitted into the O-ring coupling groove so as to seal the space between the nipple and the coupling, thereby preventing the liquefied gas from flowing between the nipple and the coupling, having at least one discharge groove, which is formed by horizontally cutting a coupling spiral protrusion formed on the inner peripheral surface of the front of the snap ring coupling groove of the coupling, so as to allow the liquefied gas that flows in when the nipple and the other pipe part are separated to flow out, and having a horn-shaped flange, which protrudes outward in an annular rim shape or is extended forward and outward and is integrally formed at the front end of the coupling so as to prevent the liquefied gas flowing out toward the front of the coupling from flowing toward the hand of a user operating the coupling.

Description

[규칙 제26조에 의한 보정 22.01.2019]　액화가스 배관용 커플링 어세이[Correction of 22.01.2019 under Article 26] Coupling Assay for Liquefied Gas Piping
본 발명은 액화가스 배관용 커플링 어세이에 관한 것으로, 상세하게는 냉매가스를 비롯한 기화성이 강한 액화가스를 배관할 때 사용되는 커플링과 배관파이프에 연결되는 니플 사이를 씰링하여 잔여가스가 일 방향으로 배출되도록 함과 동시에 커플링에 플랜지를 형성하여 배관해체 작업 시 배관에 남아있는 잔여가스로부터 작업자의 손을 보호하도록 한 액화가스 배관용 커플링 어세이에 관한 것이다.The present invention relates to a coupling assay for liquefied gas piping, and in particular, residual gas is produced by sealing between a coupling used when piping liquefied gas having a strong vaporization property, including refrigerant gas, and a nipple connected to the piping pipe. The present invention relates to a liquefied gas piping coupling assay that allows a discharge to be discharged in a direction and at the same time forms a flange in the coupling to protect the operator's hand from residual gas remaining in the piping during pipe dismantling.
산업이 발전하여 기화성이 강한 액화가스를 사용하는 용도가 많아지고 특히 에어컨이나 냉장고를 비롯한 냉동사이클에 사용되는 액화가스는 냉동효과를 향상시키기 위하여 점점 기화성을 향상시키고 있는 실정이다.With the development of the industry, the use of liquefied gas with strong vaporization is increasing, and in particular, liquefied gas used in refrigeration cycles, such as air conditioners and refrigerators, is gradually improving vaporization to improve the freezing effect.
한편, 이와 같은 높은 기화성을 갖는 액화가스는 외부로 방출시 주변의 기화잡열을 순간적으로 필요로하여 작업자의 손에 동상이나 화상을 입히는 안전사고를 유발한다.On the other hand, the liquefied gas having such high vaporization property, when discharged to the outside, requires an instantaneous vaporization heat to cause a safety accident that causes frostbite or burns to the workers' hands.
이와 같은 안전사고는 특히 조립과 해체하는 빈도가 높은 에어컨이나 냉장고의 배관해체 시 배관파이프 내부에 잔여 하는 냉매가스가 배관을 해체하는 순간 커플링과 니플사이로 흘러나와 작업자의 손에 화상이나 동상을 입히는 예가 허다하다.Such safety accidents, especially when disassembling the piping of air conditioners or refrigerators, which are frequently assembled and disassembled, cause refrigerant gas remaining inside the pipe to flow between the coupling and the nipple as soon as the pipe is disassembled, causing burns or frostbite on the operator's hands. There are many examples.
이에 지금까지 선 발명되어 실시되고 있는 배관파이프 연결구를 따른 특허문헌을 살펴보면 다음과 같다.Accordingly, the patent literature according to the piping pipe connector which has been invented and implemented so far is as follows.

배관파이프(55)에 연결하도록 외주연에 톱니형 결합돌기(15)를 형성하는 니플(10)과 그 외부의 단부에 결합되어 상대배관부(50)의 연결부에 나사결합하여 니플(10)을 밀착 결합하는 커플링(20)으로 구성하는 커플링아세이에 있어서,The nipple 10 forming a serrated coupling protrusion 15 on the outer periphery to be connected to the piping pipe 55 and the nipple 10 coupled to the external end thereof are screwed to the connection portion of the mating piping 50. In the coupling assay consisting of a coupling 20 that is in close contact,
상기 니플(10)의 선단 외주면에 스냅링결합홈(11)과 0링결합홈(12)을 형성하고, 그 외부를 감싸도록 결합하는 커플링(20)의 내주면에 상기 니플(10)의 선단 외주면에 형성한 스냅링결합홈(11)과 일치하도록 스냅링결합홈(21)을 형성하여 스냅링(30)을 끼워서 니플(10)과 커플링(20)이 분리되지 않도록 결합하며, 0링결합홈(12)에는 0링(40)을 끼워서 니플(10)과 커플링(20) 사이를 밀폐하여 액화가스가 니플(10)과 커플링(20) 사이로 흐르는 것을 방지하도록 액화가스 배관용 커플링 어세이를 구성한다.The outer circumferential surface of the tip of the nipple 10 is formed on the inner circumferential surface of the coupling 20 to form a snap ring coupling groove 11 and a 0-ring coupling groove 12 on the outer circumferential surface of the tip of the nipple 10 and surround the outside. The snap ring coupling groove 21 is formed to match the snap ring coupling groove 11 formed in the fitting, so that the nipple 10 and the coupling 20 are not separated by fitting the snap ring 30, and the zero ring coupling groove 12 ) Is inserted into the 0 ring 40 to seal the nipple 10 and the coupling 20 to prevent the liquefied gas from flowing between the nipple 10 and the coupling 20. Make up.
여기서 상기 커플링(20)의 스냅링결합홈(21) 전방 내주면에 형성된 결합나선돌기(22)를 가로 잘라서 적어도 하나 이상의 배출홈(25)을 형성하여 니플(10)과 상대 상대배관부(50)가 분리시 흘러나오는 액화가스가 흘러나가도록 형성하며, 상기 커플링(20)의 선단에 외향으로 환테 형상으로 돌출되거나 전방과 외향으로 확장된 나팔형 플랜지(26)를 일체로 형성하여 커플링(20) 전방으로 흘러나가는 액화가스가 커플링(20)을 조작하는 사용자의 손으로 흐르지 않도록 한다.Here, the coupling ring protrusion 22 formed on the front inner circumferential surface of the snap ring coupling groove 21 of the coupling 20 is cut horizontally to form at least one discharge groove 25 to form a nipple 10 and a relative relative piping portion 50 It is formed so that the liquefied gas flowing out when separating, and is formed by integrally forming a trumpet flange 26 protruding outwardly into an annular shape or extending outwardly and outwardly at the tip of the coupling 20. 20) The liquefied gas flowing forward is prevented from flowing into the user's hand operating the coupling 20.
이와 같은 본 발명의 실시 상태를 설명하면 다음과 같다.When explaining such an embodiment of the present invention as follows.
기화 시 증발잡열을 필요로 하는 액화가스는 기화성이 뛰어날수록 주변의 잡열을 급격히 흡수함으로서 액화가스를 배관하는 작업자는 액화가스가 신체에 묻거나 액화가스와 가까이 근접시 화상이나 동상을 입는 안전사고가 많이 발생한다.When evaporation, liquefied gas that requires evaporation and heat of heat absorbs the surrounding heat rapidly as the evaporation is superior, workers who pipe the liquefied gas have a safety accident that causes liquefied gas to contact the body or burn or frostbite when it is close to the liquefied gas. It happens a lot.
이와 같은 사고는 특히 가정용 냉방시스템인 에어컨을 교체하거나 수리시 커플링(20)을 풀어서 배관파이프(55)의 단부에 일체로 결합한 니플(10)을 실외기나 에어컨몸체의 상대배관부(50)로부터 분리할 때 배관파이프(55)에 남아있던 액화가스가 니플(10)과 커플링(20) 사이로 누출되어 커플링(20)을 조작하는 작업자의 손에 상해를 입히게 된다.Such an accident, especially when replacing the air conditioner, which is a household cooling system, or loosening the coupling 20 at the time of repair, connects the nipple 10 integrally coupled to the end of the piping pipe 55 from the outdoor unit or the relative piping 50 of the air conditioning body. When separating, the liquefied gas remaining in the piping pipe 55 leaks between the nipple 10 and the coupling 20, thereby injuring the hand of the operator operating the coupling 20.
이에 본 발명인 액화가스 배관용 커플링 어세이를 사용하면, 니플(10)의 선단 외주면에 형성한 0링결합홈(12)에 결합된 0링(40)이 커플링(20)의 내주면에 밀착되어 니플(10)과 커플링(20) 사이를 밀폐시켜서 액화가스가 니플(10)과 커플링(20) 사이로 누출되어 작업자가 커플링(20)을 잡고 조작하는 손이 위치하는 후방으로 누출되는 것을 방지한다.Accordingly, when the present inventors use a coupling assay for liquefied gas piping, the 0 ring 40 coupled to the 0 ring coupling groove 12 formed on the outer circumferential surface of the nipple 10 is in close contact with the inner circumferential surface of the coupling 20. As it is sealed between the nipple 10 and the coupling 20, liquefied gas leaks between the nipple 10 and the coupling 20, and leaks to the rear where the operator holds the coupling 20 and operates. Prevent things.
여기에 더하여 커플링(20)이 풀어지면서 배관파이프(55)와 일체로 결합된 니플(10)이 상대배관부(50)와 분리되는 순간 배관파이프(55)에 남아있던 액화가스는 커플링(20) 내주면에 형성한 결합나선돌기(22)를 가로 잘라서 형성한 배출홈(25)을 통하여 작업자의 손이 위치하는 후방이 아닌 실외기 등의 상대배관부(50) 방향으로 배출된다,In addition to this, as the coupling 20 is released, the liquefied gas remaining in the piping pipe 55 at the moment when the nipple 10 integrally coupled with the piping pipe 55 is separated from the relative piping 50 is coupled ( 20) Through the discharge groove 25 formed by cutting the coupling spiral projection 22 formed on the inner circumferential surface, it is discharged in the direction of the relative piping portion 50 such as an outdoor unit rather than the rear where the operator's hand is located,
이때, 배출홈(25)을 통하여 배출되는 액화가스는 커플링(20) 선단에 형성한 플랜지(26)에 의하여 커플링(20)의 외주면을 타고 작업자의 손으로 흐르는 것을 방지하게 된다.At this time, the liquefied gas discharged through the discharge groove 25 is prevented from flowing by the operator's hand on the outer circumferential surface of the coupling 20 by the flange 26 formed at the tip of the coupling 20.
여기서 커플링(20) 선단에 형성하는 플랜지(26)를 나팔형으로 형성하면 핵화가스가 기화되면서 전방 상대배관부(50) 측으로 분출되어 작업자의 손을 보호하는데 더욱 효과적일 것이다. Here, if the flange 26 formed at the tip of the coupling 20 is formed in a trumpet shape, the nucleation gas will be vaporized and ejected toward the front relative piping 50 to be more effective in protecting the operator's hand.
상기한 본 발명은 기화성이 강한 액화가스를 사용하는 기구에 배관설비 시 유용하게 이용할 수 있는 것으로 상업상 이용 가치가 대단하다 할 것이다.The above-described present invention will be useful in plumbing equipment for a device using a liquefied gas having a strong vaporization property, and will have great commercial value.
