摘要
作者选取了球阀常用密封阀座的三种型式,在液氮中进行试验。利用试验结果分析比较了三种阀座低温条件下的形态,从而得出了大口径低温球阀阀座结构设计要点。
The author selected the ball valve seal seat of three kinds of commonly used type,were tested in liquid nitrogen.Were compared and analyzed,using the test results of three kinds of seat under the condition of low temperature form,thus it is concluded that the large caliber cryogenic ball valve seat structure design points.
