进口旋塞阀密封泄露问题分析及改进措施

The reason analysis and the improved measures on seal leakage problem of imported stopcock

针对目前国外进口大口径旋塞阀在醋酸、醋酐管线上容易出现密封泄露的问题,依托技术优势研发设计新型旋塞阀,整改目前醋酸上普通旋塞阀的结构,解决了介质外漏现象,保障管线长期安全稳定。

Aiming at the problems that the seal leakage of the large-diameter imported stopcock easily appeared on the pipe line of acetic acid and acetic anhydride,based on the technology advantage,the new stopcock is researched and designed.The new design way improve the structure of ordinary stopcock,and solve the media leakage problem,which can ensure the long-term safety and steady.
