摘要
介绍国家标准GB 27790—2011《城镇燃气调压器》中调压器静特性的检验要求和判定方法,分析流量参数的调整对调压器稳压精度等级的影响,探讨了通过降低稳压精度等级和关闭压力等级的方法实现在一定程度上拓宽调压器适用流量范围。
The test requirements and judgment methods of static characteristics of pressure regulator in the national standard, namely City Gas Pressure Regulators （GB 27790 - 2011） are introduced. The impact of regulating the flow parameters on the pressure accuracy class of pressure regulator is analyzed. The methods by reducing the pressure accuracy class and lock-up pressure class are discussed in order to broaden applicable flow range of the regulator to a certain extent.
