沟槽技术

The concept of grooved pipe joining technology, as it is known today, was born into existence in 1919 when Ernest Tribe, a British Royal Engineers Lieutenant and Dr. Henry Selby Hele-Shaw, a renowned engineer, finalized a patent application of the invention of the grooved pipe coupling. Originally known as The Victory Pipe Joint Company, Victaulic began to market this revolutionary new concept in the pipe joining industry. Nearly 100 years later this grooved pipe joining technology continues to evolve and change the way the construction industry looks at piping systems. Victaulic grooved couplings, fittings & accessories provide a faster, easier and safer way to join pipe.

什么是沟槽技术?

沟槽技术的四个
关键元素:

  • 沟槽管道
  • 密封垫圈
  • 壳体
  • 螺母和螺栓

沟槽接头由这 3 个
部件组成。

管端沟槽通过铸造或加工产生。密封垫圈包围管端周边和顶部,壳体包围密封垫圈并安放于管道沟槽内,通过扳手拧紧螺栓和螺母将它们固定在一起。

沟槽接头大体分为两类:

沟槽接头

挠性沟槽接头
这些沟槽接头允许
有限的角移动量。

刚性沟槽接头
这种接头将两段管道牢牢固定住,使之不能移动,连接后的效果与法兰或焊接类似,用在管道接口不允许移动的场合。

现在,沟槽接头、沟槽管件、沟槽阀门和沟槽附件(如过滤器和导流过滤器)在世界范围内广泛而大量地应用于管道连接系统。

然而,当“沟槽”成为“更快更易安装”的代名词时,不同沟槽产品制造商的差异渐渐凸显。我们的产品独具特色。在管道系统连接领域能够同时具备可靠、耐用且构造精密的,只有 Victaulic(唯特利)。
