阀门常用材料

1、第三章阀门常用材料阀门通常由阀体、阀盖、阀瓣（闸板）、阀座、阀杆、热片、填料及驱动件（手轮、齿轮箱或气动、电动装置等）组成。我们称阀体、阀盖的材料为壳体材料（也称主体材料），闸板（阀瓣）、球体、阀座、阀杆、密封座常常称谓内件，此外还有紧固件等。按主体材料分类，人们常常把阀门分为：1. 非金属材料阀门：如陶瓷阀门、玻璃阀门、塑料阀门。2. 金属材料阀门：如铜合金阀门、铝合金阀门、铅合金阀门、钛合金阀门、蒙乃尔阀门、铸铁阀门、碳钢阀门、合金钢阀门等。3. 金属阀体衬旦阀门：如衬铅阀门、衬塑阀门、衬搪瓷阀门。我们将重点介绍金属材料阀门中的碳钢阀门和合金钢阀门。第一节壳体材料一、壳体常用材料的使用温度
