In 1776, Watt created the first practically useful steam engine, ushering in a new era of energy utilization for humanity and marking the beginning of the Industrial Revolution. Later generations designated the unit of power as the “watt” (abbreviated as “W”, symbol W). The widespread use of steam places higher and greater demands on steam traps. However, the main functions of steam traps are as follows: 1. Separating the condensate system from the steam system; 2. Removing condensate from the steam space; 3. Removing air and non-condensable gases from the steam space; 4. Establishing a proper pressure environment in the steam system; 5. Preventing steam leakage. The purpose of installing steam traps is to ensure that equipment operates as efficiently as possible. Prevent water hammer and corrosion from damaging the steam system, reducing maintenance and replacement costs as well as time required. Prevent fuel loss. No matter what, a steam drain valve can only ensure customer satisfaction by meeting these requirements. Why are drainage valves needed? Heat transfer efficiency. When it releases its vaporization heat, it will condense into the liquid phase. Since the heat contained in condensed water is much lower than that of steam, and it creates a thermal resistance, it is necessary to remove the condensed water in order to ensure efficient heat exchange. Air is a poor heat conductor. The presence of air and non-condensable gases in the heating space leads to poor heat transfer between the steam and the surface of the equipment. Experience shows that poor heat transfer prolongs heating time, reduces product quality, decreases heat output, and increases fuel costs. Therefore, it is crucial to remove air and condensed water from the vapor space in a timely manner to improve production efficiency and product quality. Damaged steam pipes and the presence of water in the equipment can cause hazards and water hammer damage. At the same time, water accumulation can lead to corrosion (such as corrosion of heat exchangers), and water hammer not only has corrosive effects but also causes damage to equipment or pipes, resulting in shutdowns for repairs. The experience of Hangzhou Watt Energy Saving shows that all of these factors will significantly increase costs, while properly eliminating condensate water can prevent the occurrence of such problems. Air vapor heats the air in the space, and the presence of non-condensable gases significantly reduces heat loss. Relying solely on steam traps to remove these gases is insufficient to meet the requirements; therefore, separate exhaust valves must be installed depending on the size of the steam space to prevent air from accumulating. At the same time, the venting capacity of some steam drain valves is not satisfactory; it is necessary to install vent valves, manual valves, plug valves with drilled holes, and fixing valves simultaneously. Since they are unable to meet the requirements arising from changes in load, none of them can effectively remove condensate water. An ideal device should be able to meet the requirements for discharging condensed water under different loads within the specified pressure range of the device. Now, steam traps that have been improved over many years can avoid the aforementioned problems and effectively remove condensate water and other gases from the steam space.
