摘　　要：在总结分析目前国内外密封垫片综合性能评价技术的基础上,利用低压区作为密封测漏腔,克服高压区密封腔由于密封难带来试验误差大的问题,自主研制一种高温垫片综合性能试验机。介绍该试验机的设计原理和特殊功能,采用高斯误差估计方法对试验机的泄漏率测量范围和精度进行计算,并利用该试验机对不锈钢柔性石墨缠绕垫片和石棉橡胶板垫片的高温综合性能进行试验评定。试验结果表明,所研制的密封垫片高温综合性能试验机能够准确进行垫片的压缩回弹性能、蠕变性能和密封性能测试,为静密封连接的泄漏预测与控制提供可靠的试验依据。Based on studying combination property evaluation technology of gasket, a new sealing gasket testing machine was developed. The machine uses low pressure sealing cavity to detect leakage, which has more precise than that using high pressure area. The design principle and special function of the machine were introduced. The measurement range and accuracy of leakage rate were estimated by Gauss error function. The combination properties of stainless steel-graphite spiral wound gasket and asbestos rubber gasket were tested. The experimentation indicates this tester can simulate compression resilience, creep relaxation and sealing performances of gaskets, and it can provide experimental basis for preventing leakage.
