A40Y带散热器弹簧全启式**阀适用于工作温度≤400℃、A40Y-1≤450℃的空气、水、氮氢混合气等介质的设备或
管路上,A40Y-P适用于工作温度≤300℃有腐蚀性介质的设备或管路上,作为超压保护装置。
设计原理根据原理,可以设想,在线(又称热态)测量或调整**阀时,如果由外部提供一个向上的附加力,则当
介质压力与这个附加力的总和刚刚克服弹簧预紧力时,阀芯同样也会开启,甚至在没有介质作用的离线(又称冷
态)条件下,单独由外部附加力克服弹簧预紧力时,阀芯也可开启,图一清楚地表示了这种力的平衡关系。 很明
显,我们可以看出,
阀芯开启的条件为
FT=FW+PL×S 其中: FT——弹簧预紧力 FW——外部附加力 PL—— 介质作用压力 S——**阀密封面
面积 则开启压力P为:P=PL+FW/S 当冷态时,P=FW/S 显然,如果能够准确地测定附加外力FW,就可以
根据已知的阀芯面积S和系统工作压力,很容易地求得**阀的开启压力P。这即为**阀在线测试技术的设计依据
和原理。
