GB 12250-89 Structural Length of Steam Traps

Steam Trap Structure Length A steam trap is an important component in a steam heating system. It is used to allow steam to escape while preventing condensate from entering the system. It ensures that the system is able to efficiently transfer heat by preventing condensate from clogging the system by blocking off the steam supply. The structure of a steam trap directly influences the efficiency of the system and the overall longevity of the unit. It is important to understand the different components that make up this critical component as well as the lengths at which each component should be installed. The first component of the steam trap is the valve. This is an important component as it regulates the amount of steam released from the system. A valve is generally composed of two parts, the control component and the valve body. The length of the valve body depends on the type of trap and the system requirements. The valve body generally has a length between two and three inches, depending on the valve size. The second component of the steam trap is the seat. This component is used to seal the valve and prevent steam from escaping past the shut off point. Seats are generally a quarter of an inch long and should be installed in a length that corresponds to the valve size. The third component of the steam trap is the stem. Stems are typically threaded and can be between one and two inches in length depending on the valve size. The forth component of the steam trap is the connecting rod. This component is attached to the seat and provides a means of securely connecting the valve and seat. The length of the connecting rod should be chosen according to the valve size. Finally, the fifth component of the steam trap is the bellows. This component is necessary to reduce the pressure of the escaping steam. The bellows typically range in size from 2.5-4 inches in length depending on the type of steam trap and system requirements. This component is also responsible for reducing and controlling the amount of noise generated during steam release. In conclusion, steam trap structure lengths are important to understand and use when installing a steam trap. The length of each component is determined by the type of trap and the system requirements and should be chosen accordingly. Proper installation ensures that the system runs efficiently and reliably, ensuring the longevity of the system.
