In daily life, we often see pressure gauges on certain pipelines. Strangely, the pipes connecting these pressure gauges are actually bent, and some are even folded. Why do these pipes have to be bent? What's the usage? ?
In fact, this type of pipe is called a pressure buffer pipe. Used to connect pressure gauges and pipelines. The bending on the pressure buffer tube is called workbench bending. It is not only circular, but also U-shaped. Cooling and preventing backflow. When measuring the pressure of a hot water pipe, people must install a curved buffer tube on the pressure gauge. This is because the water temperature in the hot water pipe is very high and the height is basically very high. When the temperature reaches 90 degrees or higher, once the hot water returns to the pressure gauge, it will be destroyed. At this point, a bent buffer tube is installed to cool the coolant and the pressure gauge, making the pressure gauge work safer.
Additionally, the purpose of doing so is to buffer pressure and protect the pressure gauge. Usually, the pressure of liquids and gases in pipelines is very high and very unstable. At this point, a curved buffer tube can be installed to cushion or immediately prevent direct impact from high pressure. Pressure gauges not only ensure that they are not damaged, but also provide more accurate measurement data, thereby ensuring the stable operation of the measurement system. Some pressure buffer tubes store a certain amount of liquid. In order to prevent the impact of cold and hot air in the pipeline, it has a good protective effect. In short, this design is clever. If you see such a curved pipe, please do not walk straight.
