摘　　要：分析了硫酸生产中高温蝶阀密封泄漏的实际情况。通过对填料函的间隙、填料材质、密封形式等进行改进探索,最终形成一种填料密封和干气密封相结合的方式,解决了硫酸生产中高温蝶阀在高温和高腐蚀的恶劣环境中频繁泄漏的问题。The actual situation of sealing leakage of high temperature butterfly valve in sulphuric acid production is analyzed. Through improving and exploring the clearance of packing box, packing material and sealing form, a combination of packing seal and dry gas seal is finally formed, which solved frequent leakage of high temperature butterfly valve in sulphuric acid production in high temperature and corrosive harsh environment.
