摘要
分析了国内有关标准对钢制阀门的壳体试验、高压密封和上密封试验等试验压力值及38℃时最大允许工作压力的规定,提出了各种金属材料的阀门试验压力值计算确定方法。
This paper analyzes the provisions of relevant domestic standards on the valve test pressures of shell test, high - pressure closure test, backseat test, and the cold working pressure at 38 degrees Cel- sius. In addition, puts forward a calculation method on steel valve test pressures which applied to com- mon metallic materials.
