After being generated in the boiler, steam is contained within a pressure pipeline and sent to heat exchange equipment; we refer to this pipeline network for transporting steam as the heat network. At the start of operation, the steel pipes at room temperature, as well as the pipe fittings and flanges, must be heated to a temperature close to that of the steam; this will cause some of the steam to condense. When steam flows through the heating network, good insulation measures are necessary, but it is still impossible to avoid heat loss to the surrounding environment due to the temperature difference between the external environment and the steam, which results in some of the steam condensing. We refer to this condensed steam as pipe losses. Steam containing some condensed water becomes humid and corrosive; as more condensed water is present, the high-speed flowing steam provides sufficient \"head pressure\" to create high-kinetic-energy \"water projectiles\". “\"Water bullets\" can cause a series of damages to steam systems; pipes, valves, elbows, flanges, instruments, and heat exchange equipment may all be deformed or damaged by the impact force of these \"water bullets,\" which can lead to safety accidents in severe cases. Therefore, this portion of condensed water must be drained promptly, which requires a trap; we generally refer to such a trap as a main line trap or pipeline trap. Improper selection of the supervisor hydrophobic valve can easily lead to air leakage and environmental pollution. If water cannot be drained in a timely manner, it will lead to water hammer and vibration.
