Abstract
The paper analyzed the sealing performance of double-offset butterfly valve by simulation method. The axial sealing performance was analyzed under conditions of friction coefficient and eccentricity as the independent variables. The lateral sealing performance was analyzed under conditions of gas pressure and ring compaction as independent variables. Conclusions show that the key factors affecting the reliability of axial sealing and lateral sealing are the eccentricity, gas pressure and ring compaction, respectively. As the eccentricity decreases, the axial sealing will be more reliable, and as the gas pressure or the ring compaction increase, the reliability of the lateral sealing will also increase.
