供水管道的阀门附近常安装有伸缩器,管道伸缩器在供水管道中能起到重要的作用,一方面可以为管道检修提供拆卸阀门的便利,另一方面,它作为供水管网的重要辅助配件之一,能够实现一定程度上的轴向伸缩,也可以克制由于管道对接不足而发生的小角度范围内的位移。它既解决了阀门安装与拆卸的施工难度,又在一定范围内补偿了由于热胀冷缩产生的伸缩变形。所以,管道伸缩器在供水管网的设置中被广泛的应用。然后,应用不合理也会导致管道运行不良的后果。本文主要就管道伸缩器的选择及不同部位的安装进行了探讨。
Water supply pipe valves are often installed near the expansion joints, pipe expansion joints in the water supply pipe can play an important role, on the one hand, can provide the convenience of dismantling the valve for pipe inspection, on the other hand, it is an important accessory for water supply pipe network Can achieve a certain degree of axial expansion and contraction, and can also restrain the displacement in the small angle range caused by insufficient pipe docking. It not only solves the difficulty of valve installation and disassembly, but also compensates for the expansion and contraction due to thermal expansion and contraction within a certain range. Therefore, the pipe expansion joints in the water supply network settings are widely used. Then, the application of unreasonable pipeline can lead to poor results. This article mainly discusses the choice of pipe expansion joints and the installation of different parts.
