一、密封垫片简介:
Description of sealing gasket
密封件作为管道和设备法兰连接的主要元件,对密封起着重要作用。其密封系借助螺栓压紧垫片,使垫片在螺栓压紧力的作用下发生塑性或弹性变形以堵塞法兰压紧面的缝隙而达到密封效果。
密封件主要有金属缠绕垫、金属包垫、高强石墨复合垫、聚四氟乙烯包覆垫、齿形垫、透镜垫、金属环垫、椭圆垫、橡胶石墨垫及填料等。
Sealing gasket is the main component connecting pipes and equipment's flanges, which is very important for sealing.
The function of sealing is under the help of pressing force from the bolts to make gasket undergoes plasticity or flexible
deformation and to plunge the gap of flange's clamping surface for the purpose of good sealing.
