에어컨 실외기용 수지코팅 알루미늄 배관 연결구{refrigerant pipe connector for air conditioner of outdoor fan}Resin-coated aluminum pipe connector for air conditioner outdoor unit {refrigerant pipe connector for air conditioner of outdoor fan}

본 명세서는 에어컨 실외기용 배관 연결구에 관한 것으로, 보다 구체적으로 설명하면, 실외기의 서비스밸브에 냉매관(수지코팅 알루미늄 배관을 말함)을 확관방식에 의해 실링상태로 이음연결하기 위한, 에어컨 실외기용 수지코팅 알루미늄 배관 연결구에 관한 것이다.The present specification relates to a pipe connector for an air conditioner outdoor unit, and more specifically, a resin for an air conditioner outdoor unit for jointly connecting a refrigerant pipe (referring to a resin coated aluminum pipe) to a service valve of the outdoor unit in a sealed state by an expansion method. It relates to a coated aluminum pipe connector.

본 명세서에서 달리 표시되지 않는 한, 이 섹션에 설명되는 내용들은 이 출원의 청구항들에 대한 종래 기술이 아니며, 이 섹션에 포함된다고 하여 종래 기술이라고 인정되는 것은 아니다.Unless otherwise indicated herein, the content described in this section is not prior art to the claims of this application, and inclusion in this section is not admitted to be prior art.

일반적으로, 에어컨의 냉매 배관, 가스 배관 등 각종 배관을 소정의 기계적 장치에 연결하기 위해서는 배관의 연결구조가 필요하게 된다.In general, in order to connect various types of pipes such as refrigerant pipes and gas pipes of an air conditioner to predetermined mechanical devices, a connection structure of pipes is required.

이러한 배관의 연결구조는 기본적으로 내부의 유체 누수 또는 누설되는 것을 방지하여야 하며, 진동이나 외부의 충격에 의해 이완되지 않아야 하는 등의 조건을 충족시켜야 된다.The connection structure of these pipes should basically prevent internal fluid leakage or leakage, and satisfy conditions such as not being relaxed by vibration or external shock.

일 예로서, 배관의 연결구조는 배관의 단부를 나팔관처럼 확관시키되, 확관부를 중간에 끼운 상태에서 너트와 볼트를 상호 결합하여 조임에 따라 확관부가 볼트의 선단부에 밀착됨으로써 기밀을 유지할 수 있다.As an example, in the connection structure of the pipe, the end of the pipe is expanded like a fallopian tube, but the expansion part is in close contact with the distal end of the bolt as it is tightened by combining the nut and the bolt with the expansion part inserted in the middle to maintain airtightness. .

도면에는 미 도시되었으나, 배관(에어컨의 냉매 배관)의 확관부와 볼트 사이에 합성수지재 등으로 성형되는 슬리브를 게재시켜 이음연결하게 되는 데, 배관을 이음연결하는 작업현장에서 작업자가 너트와 볼트를 상호 결합하여 체결시 필요이상으로 힘을 가하여 체결하게 된다.Although not shown in the drawing, a sleeve formed of synthetic resin, etc. is placed between the expansion part of the pipe (refrigerant pipe of the air conditioner) and the bolt to connect the joint. At the work site connecting the pipe, the operator uses nuts and bolts. When they are combined with each other, they are tightened by applying more force than necessary.

이로 인해, 볼트 선단부와 접촉되는 슬리브가 필요이상의 외력을 받아 형상 변형(크랙 또는 찌끄러짐 발생)이 발생될 경우에 형상 변형으로 인해 틈새가 발생되고, 틈새를 통해 냉매가 누출될 수 있는 문제점을 갖게 된다.For this reason, when the sleeve in contact with the bolt tip is subjected to more external force than necessary and a shape deformation (cracking or crushing occurs), a gap is generated due to the shape deformation, and a refrigerant may leak through the gap. do.

본 명세서의 실시예는, 냉매관을 이음연결하는 작업경험이 부족한 작업자가 냉매관의 확관부를 파손시키지않고 서비스밸브에 쉽게 이음연결할 수 있도록 한, 에어컨 실외기용 수지코팅 알루미늄 배관 연결구와 관련된다.An embodiment of the present specification relates to a resin-coated aluminum pipe connector for an air conditioner outdoor unit so that an operator who lacks experience in jointing and connecting the refrigerant pipe can easily connect the refrigerant pipe to the service valve without damaging the expansion pipe.

본 명세서의 실시예는, 이종 재질의 서비스밸브, 압축링에 대해 냉매관의 확관부가 직접 접촉되어 갈바닉(galvanic) 부식되는 것을 방지할 수 있도록 한, 에어컨 실외기용 수지코팅 알루미늄 배관 연결구와 관련된다.An embodiment of the present specification relates to a resin-coated aluminum pipe connector for an air conditioner outdoor unit to prevent galvanic corrosion by directly contacting the expansion pipe of a refrigerant pipe with a service valve and a compression ring made of different materials.
