查询词典 buttress thread

It is pointed out that the inherent reason of the leakage is that the buttress thread is adopted, and the outer reasons of the leakage lie in poor quality sealing ring being used, the design of sealing groove being unreasonable, and the thread sealing compound failing at 350℃.

指出偏梯形螺纹连接本身存在较大的泄漏通道，是造成泄漏的内在原因；工厂为弥补这一缺陷而设计的密封圈质量较差、密封槽设计不合理，以及所使用的螺纹脂不耐350℃高温，是造成隔热管泄漏的外在原因。
