截止阀密封面宽度对泄漏量影响的试验研究

Test and study on the sealing surface width of globe valve influencing on leakage rate

通过试验 ,得出了金属硬密封截止阀随口径的增大 ,最小泄漏点密封面宽度增加的规律 。

Reaching a law relating to the width increasing of sealing surface of minimum leaking point accompanied by increasing bores for metal to metal sealed globe valves,and summarizing approximate formulas of leakage rate and sealing surface width relations of various bores for globe valves.
