摘　　要：钢制底阀在道路运输危险液体货物过程中时有发生的受撞击或碰撞后破裂或变形导致泄漏、燃爆的潜在危险日益突出,主要因为国内无相应测试装置、无法评价该性能,使该性能成为质量盲点。从钢制底阀的发展现状、材质特性、使用工况、泄漏检测以及国内外标准规定的加载30°变形的安全性能等方面,提出了基于液压推力变形原理的钢制底阀安全性能液压测试装置的设计方案,为解决钢制底阀破裂或变形以及阀座密封关键性能无法评价的行业共性难题提供思路,为完善底阀不同材质性能特性理论研究奠定基础。In the process of road transportation of dangerous liquid goods,the potential danger of leakage and combustion explosion caused by impact or rupture or deformation after collision is increasingly prominent.The main reason is that there is no corresponding test device in China and the performance cannot be evaluated,so that it becomes a quality blind spot.Based on the development status of steel foot valve,material characteristics,working conditions,leakage detection and safety performance of loading 30°deformation stipulated by domestic and foreign standards,the design scheme of hydraulic test device for safety performance of steel foot valve based on hydraulic thrust deformation principle is put forward.It provides ideas for solving the common problems of steel foot valve rupture or deformation and the key performance of valve seat sealing been not evaluated in the industry,and lays a foundation for improving the theoretical research on the performance characteristics of different materials of foot valve.
