Description
本実用新案は分岐管の技術分野に関し、特に打込式分岐管に関する。 This utility model relates to the technical field of branch pipes, and more particularly to a drive-type branch pipe.
分岐管はセントラルエアコン分岐管または枝管、マニホールドとも呼ばれ、VRF空調システムに使用されており、ホストマシンと複数のエンドデバイスを接続する接続チューブとして、一般的に気管と液管に分かれる。通常気管の直径が液管より大きい。その理由は、気体の相対フローエリアが液体よりもはるかに大きいからである。液管は小径配管を使用すればいい。空調機の冷媒が凝縮器の出口から排出されてから、スプリッターの液管につながり、冷媒が液管による分流で他の分岐管やエンドエバポレータに分流されることができる。冷媒が蒸発器内に熱を吸収し気体になってから、気管を通じてホストマシンの圧縮機に流れ戻し、分岐管の口部と外部配管とが通常溶接で接続される。その欠点は、溶接による外部配管との接続をするとき溶接部への酸化物の混入、サンドホールや溶接部剥離、酸化腐食後の漏れなどが発生しやすい。例えば、中国特許出願公開番号：CN203132225Uは、三方管、三方管の単口端に接続されているメイン配管、三方管の両口端にそれぞれ接続されているストレート配管と曲がり配管を備え、前記曲がり配管がスプリット構造となり、スプリット型曲がり配管が固定曲がり配管と曲がり接続配管を備え、固定曲がり配管の一端と三方管の両口端の一端とが固定的に接続されており、固定曲がり配管のもう一端と前記曲がり接続配管の一端とが接続されており、固定曲がり配管が両端の直管部分と中央の曲がり部分より構成され、固定曲がり配管の両端の直管部分の軸線による夾角が120~150°であり、曲がり接続配管が両端の直管部分と中央の曲がり部分より構成され、曲がり接続配管の両端の直管部分の軸線による夾角が120~150°であることを特徴とする「空調分岐管」を開示した。この実用新案は1組の分岐管のみを使用し、別にエルボーベンドを使用しなくても、２つの分流管の並行と垂直を実現できるが、気体入口部と気体出口部が溶接で接続されているので、サンドホールや溶接部剥離、酸化腐食後の漏れなどが発生しやすい。 A branch pipe is also called a central air conditioner branch pipe, branch pipe, or manifold, and is used in a VRF air conditioning system. Generally, a branch pipe is divided into a trachea and a liquid pipe as a connection tube connecting a host machine and a plurality of end devices. Usually the trachea is larger in diameter than the liquid tube. The reason is that the relative flow area of the gas is much larger than the liquid. The liquid pipe may be a small diameter pipe. After the refrigerant of the air conditioner is discharged from the outlet of the condenser, the refrigerant is connected to the liquid pipe of the splitter, and the refrigerant can be diverted to other branch pipes and end evaporators by the diversion by the liquid pipe. After the refrigerant absorbs heat into the evaporator and becomes gas, it flows back to the compressor of the host machine through the trachea, and the mouth of the branch pipe and the external pipe are connected by normal welding. The disadvantage is that when connecting to an external pipe by welding, oxides are mixed into the welded part, sand holes and welded parts are peeled off, and leakage after oxidative corrosion is likely to occur. For example, the Chinese Patent Application Publication Number: CN203132225U includes a three-way pipe, a main pipe connected to a single-port end of the three-way pipe, a straight pipe and a bent pipe connected to both ends of the three-way pipe, respectively. The pipe has a split structure, the split bent pipe has a fixed bent pipe and a bent connecting pipe, and one end of the fixed bent pipe and one end of both ends of the three-way pipe are fixedly connected. One end and one end of the bent connecting pipe are connected, the fixed bent pipe is composed of a straight pipe portion at the both ends and a central bent portion, and the depression angle due to the axis of the straight pipe portion at both ends of the fixed bent pipe is 120 to 150. The bend connection pipe is composed of a straight pipe portion at both ends and a central bend portion, and the depression angle by the axis of the straight pipe portion at both ends of the bend connection pipe is 120 to 150 °. It disclosed the air conditioning branch pipe ". This utility model uses only one set of branch pipes, and without using an elbow bend, the parallel and vertical of the two shunt pipes can be realized, but the gas inlet and the gas outlet are connected by welding. As a result, sand holes, weld delamination and leakage after oxidative corrosion are likely to occur.
溶接による外部配管との接続をするとき溶接部への酸化物の混入、サンドホールや溶接部剥離、酸化腐食後の漏れなどが発生しやすい。 When connecting to an external pipe by welding, oxides are likely to be mixed into the welded part, sand holes and welded parts are peeled off, and leakage after oxidative corrosion is likely to occur.
