[기술배경][Technology Background]

본 고안은 동 및 동합금관 이음쇠에 관한 것으로, 특히 이음동관이 끼움결합되는 이음쇠몸체의 접속개구부 안으로 납땜용접시의 땜납이 모세관현상에 의해 용이하게 침투 확산되면서 용접결합될 수 있도록 한 동 및 동합금관 이음쇠에 관한 것이다.The present invention relates to copper and copper alloy pipe fittings, in particular, copper and copper alloy pipes that allow the solder during welding to be easily penetrated and spread by the capillary phenomenon into the connection opening of the fitting body into which the fitting copper pipe is fitted. It is about fittings.

[종래의 기술][Prior art]

시대가 복잡해지고 과학기술이 발전됨에 따라 현대인은 편안하고 안락한 주거환경의 분위기를 추구하고 있는 실정이다. 그 일례로 동절기에 맞는 주거환경을 영위하기 위한 난방수단으로 보일러를 설치하여 실내를 난방시키거나 필요한 양의 온수를 이용할 수 있도록 하고 있다.As the times become more complex and science and technology develop, modern people are pursuing the atmosphere of comfortable and comfortable living environment. For example, a boiler is installed as a heating means for maintaining a residential environment suitable for the winter so that a room can be heated or a required amount of hot water can be used.

이러한 보일러에 있어, 해당 평수의 실내바닥에 설치되는 배관은 중간중간에 이음쇠로 연결되어 해당 장소로 배관의 방향을 전환시키거나 분기시켜 필요한 량의 난방수를 여러 장소로 공급 순환시키게 되는데, 이들 이음동관은 이음쇠를 매개로 끼움연결하고 일반 땜납이나 인동땜납으로 용접결합시켜 순환되는 난방수가 누수되지 않도록 한다.In such boilers, the pipes installed on the indoor floor of the plain water are connected by fittings in the middle to divert or divert the pipes to the corresponding place to supply and circulate the required amount of heating water to various places. Copper pipes are fitted with fittings and welded together with ordinary solder or copper solder to prevent circulating heating water leakage.

그런데, 이렇게 동관 사이에 끼움연결되는 이음쇠를 용접결합시킴에 있어 이들 동관과 이음쇠가 밀폐끼움된 연결구조를 갖기 때문에, 이들 연결부위에 용접되는 땜납이 연결부위 안으로 침투되지 못하고 중력에 의해 주변으로 흘러내리면서 이음동관과 이음쇠와의 경계부위 선접합면에만 용접결합되므로 신뢰성있는 정확한 용접작업이 이루어지기 힘들다는 문제점이 있었다.However, in welding the fittings that are fitted between the copper tubes, the copper tubes and the fittings have a sealed fitting structure, so that the solder welded to these joints does not penetrate into the joints and flows to the surroundings by gravity. As it is lowered, the welding joint is connected only to the line junction surface between the joint pipe and the fitting, and thus there is a problem that a reliable and accurate welding operation is difficult.

[고안의 목적][Purpose of designation]

Concave-convex portions are formed in the longitudinal direction at regular intervals.

또한, 상기 접속개구부에 납땜시의 납땜이 균일하게 스며들면서 용접결합되도록 요철부 대신에 내주면이 확장된 동관이음부가 각각 돌출형성된 것을 특징으로 한다.In addition, the copper pipe joints each having an inner circumferential surface extended instead of the uneven parts may be formed to protrude so that the solder at the time of soldering is uniformly infiltrated with the solder.
