Why does the tube under the pressure gauge bend? I didn't know it would matter so much!
In life, we often see pressure gauges in certain pipes. Oddly, the tubes that connect these gauges are actually bent, and some are even folded. Why do these pipes have to bend? What's the use?

In fact, this type of tube is called a pressure buffer tube. For connecting pressure gauge and pipe. Bending on the pressure buffer tube is called bench bending. It's not only circular, it's u-shaped. Cool and cool and prevent reflux. When measuring the pressure of the hot water pipe, one must install a curved buffer in the pressure gauge. This is because the water temperature in the hot water pipe is very high and basically very high. When it reaches 90 degrees or higher, once the hot water returns to the gauge, it will be destroyed. At this point, a curved buffer tube is installed to cool the coolant and cool the gauge, making it safer to work.
In addition, the purpose is to cushion the pressure and protect the gauge. Usually, the pressure on the liquid and gas in the pipe is very high and very unstable. At this point, a bent buffer tube can be installed to buffer or immediately prevent direct impact of high pressure. The pressure gauge can not only ensure that the pressure gauge is not damaged, but also can obtain more accurate measurement data, thus ensuring the stable operation of the measurement system. Some pressure buffers store a certain amount of liquid. In order to prevent the cold air and hot air in the pipeline impact, it has a good protective effect. In short, the design is clever. If you see a bent tube like this, please do not go straight.
