静密封(英文翻译）.rar

1.1 Introduction
The designs and types of sealing methods for static duties cover a vast range. To
discuss the various types it is useful to divide them into two basic categories, seals and gaskets. Seals are typified by an elastomeric O-ring in a seal groove and gaskets by fibrous materials clamped between a pair of flanges.
Seals, within this context are designed such that they are expected to be self-energizing whereas it is normal for gaskets to be clamped with sufficient force that the pressure is resisted by the stored energy within the gasket. Hence the relative assembly load for a seal may be much lower than a gasket for the same duty.
There are many variations on these two individual themes and several that cover a grey area between them. The selection will depend on a number of factors. These include:

1.1介绍
静态密封设计的方法和类型涵盖了广阔的范围。为了讨论其不同的使用方法，我们将其分为两个基本的类别，即为密封件和垫圈。密封是典型的将一个O型橡胶圈在一个密封槽和垫圈之间装夹着一对法兰盘。
密封，在这方面是这样设计的，他们预计将自激而这是正常的垫圈被夹有足够的力量，抵制压力是由储存能量在垫片。因此相对装配负荷密封可能远低于垫片相同的职责。
有许多变化，这些个人的主题和几个盖之间的灰色地带他们。选择将取决于若干因素。
