Description

동관 접속장치Copper tube connecting device

본 고안은 동관의 접속장치에 관한 것으로, 특히, 철관과 동관이나 강관과 동관, 또는 동관과 동관사이에 접촉부식이나 전식현상을 미연에 방지할 수 있도록 한 것을 특징으로 하는 동관의 접속장치에 관한 것이다.The present invention relates to a copper tube connecting device, and more particularly, to a copper tube and a copper tube or a steel tube and a copper tube, or to a copper tube connecting device characterized in that it can prevent contact corrosion or transfer phenomenon between the copper tube and the copper tube. will be.

근래에 이르러 동관은 열전도성이 뛰어남으로 인하여 난방용 배관자재로서 널리 사용되게 되었고, 이와 같은 동관은 온·냉수용 철제 물탱크와 배관의 연결부분이나 수전류와 배관의 연결부분, 또는 펌프류와 배관의 연결부분 및 가스배관 등에서 철관과의 저속 또는 동관끼리의 접속에 의하여 필요한 장소로 접속배관 되는데, 이와 같은 동관 접속부에는 접속되는 상대 관과의 재질 차이로 인하여 접촉부식이나 전식현상이 나타나므로 관의 접속부를 절연처리 하여 주는 일이 매우 중요하다.In recent years, copper pipes have been widely used as heating piping materials because of their excellent thermal conductivity. Such copper pipes are used as hot water and cold water steel tanks and pipe connections, water current and pipe connections, or pumps and pipes. In the connecting part and gas pipe, etc., the pipe is connected to the required place by the low speed with the steel pipe or the connection between the copper pipes.The copper pipe connection part has contact corrosion or electroforming phenomenon due to the material difference with the other pipe to be connected. It is very important to insulate.

그뿐만 아니라, 동관은 일반 철관이나 강관과는 달리 접속단부에 접속플렌지를 용접부착 하는 것이 불가능함에 따라 같은 동재질로 된 동어댑터를 사용하여 접속플렌지 역할을 수행하도록 구성하므로서 동관을 접속시키도록 구성되어 있다.In addition, the copper tube is configured to connect the copper tube by performing the role of a connecting flange using a copper adapter made of the same material as it is impossible to weld attach the connection flange to the connection end unlike the general steel pipe or steel pipe. It is.

종래에 사용되어온 동관의 접속장치는 첨부도면 도 1 내지 도 2에서 보는 바와 같이, 주관(101)의 접속단부에 다수의 볼트공(103)을 구비한 접속플렌지(102)를 용접부착 하고, 동관(104)의 접속단부에 다수의 볼트공(106)을 구비한 절연플렌지(105)를 삽입한 상태에서 절곡단턱(108)이 형성된 동어댑터(107)를 용접부착하여 주관(101)의 접속플렌지(102)와 동어댑터(107)의 접속단부 사이에 다수의 볼트공(111)을 구비한 고무패킹(110)을 삽입한 다음에 각 볼트공(103)(106)(111)을 통하여 접속플렌지(102)와 절연플렌지(105) 및 고무패킹(110)을 와셔(112)를 끼운 상태에서 체결볼트(113)와 너트(114)로 체결하여서 구성된 것이었다.Conventionally used copper tube connecting device, as shown in the accompanying drawings, Figures 1 to 2, the welding flange is provided with a connecting flange 102 having a plurality of bolt holes 103 at the connecting end of the main pipe 101, The connecting flange of the main pipe 101 is welded by welding the copper adapter 107 having the bending step 108 formed in the state where the insulating flange 105 having the plurality of bolt holes 106 is inserted into the connecting end of the 104. A rubber packing 110 having a plurality of bolt holes 111 is inserted between the 102 and the connection end of the copper adapter 107, and then through each of the bolt holes 103, 106, 111 through a connection flange. (102) and the insulating flange 105 and the rubber packing 110 was configured by fastening with the fastening bolt 113 and the nut 114 in the state in which the washer 112 is fitted.

이와 같이 구성된 종래의 동관 접속장치는 동어댑터(107)의 접속단부에 형성된 절곡단턱(108)의 폭이 비교적 협소할 뿐만 아니라, 그 절곡단턱(108) 자체가 관중심부측으로 인장력을 받는 것에 대하여 대응 저지력을 나타낼 수 없도록 구성되어 있음에 따라 배관라인내에 워터해머 현상 등의 고압유체압력이 걸리면 그 압력이 절곡 단턱에 걸리게 되어 절곡단턱(108)이 관중심부로 인장력을 받게 되는 결과 절곡단턱(108)에 왜곡 변형현상이 나타나게 되고, 그 결과 고무패킹이 파열 또는 파손되어 누수가 발생하는 문제점이 있었고, 또한, 종래에는 절연플렌지(105)가 단순한 철제로 되어 있어 절연의 효과가 미흡하여 접촉부식 또는 전식현상을 철저히 방지할 수 없는 문제점도 있었다.The conventional copper tube connecting device configured as described above has a relatively narrow width of the bending step 108 formed at the connection end of the copper adapter 107, and responds to the bending step 108 itself being tensioned toward the center of the tube. When the high pressure fluid pressure such as a water hammer phenomenon is applied to the pipe line, the pressure is applied to the bending step so that the bending step 108 receives the tensile force to the center of the pipe. There was a problem in that distortion deformation occurred, and as a result, there was a problem in that the rubber packing was ruptured or broken, causing leakage. In addition, the insulating flange 105 is made of simple iron, so that the effect of insulation is insufficient. There was also a problem that can not prevent the phenomenon thoroughly.

본 고안의 목적은 전술의 종래 문제점을 개선한 새로운 형태의 동관 접속장치를 제공하기 위한 것이다.An object of the present invention is to provide a new type of copper tube connecting device that improves the above-mentioned conventional problems.

Insert a rubber packing with a number of bolt holes between the connection flange of the main pipe and the connection end of the copper adapter, and then tighten the bolts with the connecting flange, insulating flange and rubber packing through the bolt holes. Formed by fastening with a nut, the bending flange formed by connecting a plurality of bolt holes at the connection end of the copper adapter extends to extend to the outer edge of the insulating flange, while the entire outer circumference of the insulating flange is coated with an insulating layer such as Teflon resin. Thus, the width of the flange portion of the copper tube can be secured to a great extent, and a fastening bolt is attached to a bolt hole provided in the flange portion of the copper tube. The fastening bolts of the present invention are designed to prevent distortion of the flange portion by providing a firm countermeasure against the tension of the flange portion to be pulled to the center of the tube as the high pressure fluid pressure such as water hammer phenomenon is applied. Another object of the present invention is that the entire outer periphery of the insulating flange is coated with an insulating layer such as Teflon resin to improve the insulation effect to achieve the bar, hereinafter The invention is described by the drawings as follows.
