閥門毛坯的選擇原則與機械加工餘量

一、閥門毛坯的選擇原則機械加工常用的毛坯有鑄件、鍛件、型材及焊接件。不同的毛坯種類以及毛坯的精度、粗糙度和硬度等對機械加工工藝過程有着直接的影響。選擇閥門毛坯時應考慮如下的一些因素。①零件的材料及對材料的組織和性能要求。設計圖上規定的零件材料,大體上就決定毛坯的種類。例如,零件材料為鑄鐵就必須用鑄造方法來制造毛坯。對于鋼制零件,在選擇毛坯時應考慮對材料的力學性能要求。例如,制造高壓閥門的零件一般應

高性能三偏心雙向硬密封蝶閥的應用

    目前,蝶閥作為一種用來實現管路系統通斷及流量控制的部件,已在石油、化工、冶金、水電等許多領域中得到極為廣泛地應用。在已公知的蝶閥技術中,其密封形式多采用密封結構,密封材料為橡膠、聚四氟乙烯等。由于結構特征的限制,不适應耐高溫、高壓及耐腐蝕、抗磨損等行業。現有一種比較先進的蝶閥是三偏心金屬硬密封蝶閥,閥體和閥座為連體構件,閥座密封表面層堆焊耐溫、耐蝕合金材料。多層軟疊式密
