本文提出了天然气计量调压站应该简单、轻便的观点，在建设设计中应首先考虑安全、准确、经济和可靠。文章论述了天然气计量调压站设计参数的选取原则及管线、管汇、控制阀、阀门、超压保护和计量仪表的设计原则和方法。 This paper puts forward the idea that natural gas metering and pressure regulator station should be simple and light, and safety, accuracy, economy and reliability should be the first consideration in the construction design. The paper discusses the selection principle of design parameters of natural gas metering and pressure regulating station and the design principles and methods of pipeline, manifold, control valves, valves, overpressure protection and measuring instruments.
