| Abstract: | This paper introduces the necessity of drain and vent of the long distance pipeline and pipe-line valves from the pipeline engineering practice. The influence of drain and vent on the piston effectseat is analysed. The design of the pipeline valve seat piston effect must combine with the actual needsof drain and vent, truly embodying the DBB function of the pipeline valve. |
