在蒸汽供热系统设计中,我们常常会遇到这样一个问题:高压凝结水在回送途中要不断二次汽化,加上疏水器的漏汽,余压凝结水管中必然是汽水两相流动。因此,当凝结水改变流动方向时,极易发生水击。水击会发出噪声和振动,严重时能破坏管件接口的严密性及管道支架,所以,应尽量防止水 In the design of steam heating systems, we often encounter such a problem: high-pressure condensate must be vaporized in the middle of the second return, plus steam leakage from the steam trap, and the residual pressure condensate water pipe must be a two-phase flow of soft drinks. Therefore, when the condensate changes its direction of flow, it is prone to water hammer. Water hammer will emit noise and vibration. In severe cases, it can damage the tightness of pipe fittings and pipe supports. Therefore, water should be prevented as much as possible.
