聚四氟乙烯作为阀门密封面的必需比压值有不同的公式和经验数据,本文对这些公式和经验数据进行了分析。通过实验,提出了几种常用的填充聚四氟乙烯用在常温、低压(小于16kgf/cm~3)空气介质的必需比压曲线。图9,表4,参考文献2。
PTFE valve sealing surface of the necessary specific pressure values have different formulas and empirical data, the paper analyzes these formulas and empirical data. Through experiments, some commonly used polytetrafluoroethylene (PTFE) filled with the required pressure curve at room temperature, low pressure (less than 16kgf / cm ~ 3) air medium is proposed.
