As another important component of fluid control, the plug valve also has a variety of structural forms. Common types include straight through packing, triangular packing, and quaternary packing. Meanwhile, the oil seal straight through type and T-shaped triangle type are also common structures in plug valves. Understanding these structural form codes helps us to have a more comprehensive understanding of the performance and application characteristics of plug valves.
In addition, as an important device for protecting the safety of fluid systems, the structural form code of safety valves also deserves our attention. For example, a fully open safety valve with a spring closure and heat sink is one of the common and high-performance safety valve structures. By understanding these structural form codes, we can better select safety valves that are suitable for practical needs, ensuring the safe and stable operation of the fluid system.
