金属环垫安装在法兰表面的梯形环槽中。拧紧连接螺栓时,径向收缩和左右梯形槽紧固,产生塑性变形,产生环形密封带,形成原始密封。变压后,在物质压力的作用下,环垫轴向膨胀。垫片与梯形槽的斜坡更为帖紧,产生自紧功效。然而,物质压力的增加也会改变法兰和连接螺栓,导致密封面之间的相对分离,垫片密封比相对降低。因此,环垫可视为半自密封。1.耐热性.耐高压,适用于高压法兰;2.长期可靠密封;3.适应压力.温度波动的工况标准。金属环垫与法兰槽的匹配主要是表面接触。与椭圆形环垫相比,虽然不容易与法兰槽紧密结合,但可以重复使用,而且由于横截面由直线组成,易于处理。同时,八角金属环垫材料的强度应小于法兰15~20HB。

椭圆形金属环垫特性特点:

1、耐热、耐高压,适用于髙压法兰;

2、密封长久可靠;

3.适应压力.工况条件的温度波动;

应用范围:管法兰、塔槽、压力容器、高速接合面、高温高压阀盖一般用于高温高压蒸汽、气体、溶剂。石油化工工业中的井口装置和采油树上的密封

椭圆垫起源于美国,早在20世纪20年代就用于锅炉行业,然后用于密封人孔盖和高压釜的其他窗口。这在石油生产和炼油行业尤为重要。随着蒸汽动力系统温度和压力的升高,金属环垫的使用越来越普遍。
