在北美和世界上许多国家PVC管道的连接,是通过橡胶密封圈的方式,承插后有效防止管道连接处漏水。传统的后置密封圈是无增强的,需要在施工现场或制造工厂,手工安装到预扩口的管道中。本文介绍了一种在北美PVC管道中应用超过90%以上的,一体成型的钢骨架密封圈连接。一体成型的钢骨架密封圈胶圈用临近的内部的或外部的钢圈加强,在扩口的过程中纳入管道中。这种永久性增强密封圈提供了对管道结构上的支撑以及橡胶圈的预先压缩,可实现快速安装,有利于保证管道连接密封的可靠性和安全性。
In many North American countries and the world PVC pipe connections, through the rubber ring, after the socket to prevent leakage at the pipe joints. Conventional rear seals are non-reinforced and require manual installation into pre-flared pipes at construction sites or in manufacturing facilities. This article describes a one-piece, steel-framed gasket connection that is used in more than 90% of North American PVC pipe applications. The integrally formed steel skeleton ring rubber ring with the adjacent internal or external steel ring reinforcement, in the process of flaring into the pipeline. This permanently reinforced seal provides structural support for the pipe and pre-compression of the rubber ring for quick installation and helps ensure the reliability and safety of the pipe connection seal.
