閥門常用材料

1、第三章閥門常用材料閥門通常由閥體、閥蓋、閥瓣（閘板）、閥座、閥桿、熱片、填料及驅(qū)動(dòng)件（手輪、齒輪箱或氣動(dòng)、電 動(dòng)裝置等）組成。我們稱閥體、閥蓋的材料為殼體材料（也稱主體材料），閘板（閥瓣）、球體、閥座、閥桿、密封座 常常稱謂內(nèi)件，此外還有緊固件等。按主體材料分類，人們常常把閥門分為：1. 非金屬材料閥門：如陶瓷閥門、玻璃閥門、塑料閥門。2. 金屬材料閥門：如銅合金閥門、鋁合金閥門、鉛合金閥門、鈦合金閥門、蒙乃爾閥門、鑄鐵閥門、碳鋼閥門、合金鋼閥門等。3. 金屬閥體襯旦閥門：如襯鉛閥門、襯塑閥門、襯搪瓷閥門。我們將重點(diǎn)介紹金屬材料閥門中的碳鋼閥門和合金鋼閥門。第一節(jié)殼體材料一、殼體常用材料的使用
