带螺母的螺丝中,垫片的作用主要是:增大接触面积,减小压力,防止松动,保护零件和螺丝。

垫片是两个物体之间的机械密封,通常用以防止两个物体之间受到压力、腐蚀、和管路自然地热胀冷缩泄漏。由于机械加工表面不可能完美,使用垫片即可填补不规则性。

垫圈是薄板(通常圆型)的一个漏洞(通常在中间)通常是用于分配的负荷线程紧固件。其他用途是作为间隔,弹簧(贝尔维尔垫片,波垫片) ,耐磨垫,预显示装置,锁装置。通常垫片外径是内径的两倍左右 。

垫片厚度与其形式、材料、直径、密封面状况和密封介质等有关。对大多数非金属板状片而言,通常采用较薄的1.5mm或2mm厚垫片。这是因为较薄的垫片,暴露在内压下的表面积较小,介质沿本体渗漏少,故泄漏率较低,且垫片向外挤出的力也较小;较薄的垫片有较低的蠕变松弛;垫片越薄,价格也越低。

但是,垫片必须填补不规则的法兰密封面,较厚的垫片压缩性好,对损伤或瓢曲不大的密封面有一定的适应能力。因此,垫片的厚度取决于法兰表面粗糙度、垫片的压缩性、垫片应力、法兰的偏转程度等。
