style="text-indent:25px">閥門模具在工作中除了要求基體具有足夠高的強(qiáng)度和韌性的合理配合外，其表面性能對模具的工作性能和使用壽命至關(guān)重要。這些表面性能指：耐磨損性能、耐腐蝕性能、摩擦系數(shù)、疲勞性能等。這些性能的改善，單純依賴基體材料的改進(jìn)和提高是非常有限的，也是不經(jīng)濟(jì)的，而通過表面處理技術(shù)，往往可以收到事半功倍的效果，這也正是表面處理技術(shù)得到迅速發(fā)展的原因。閥門模具的表面處理技術(shù)，是通過表面涂覆、表面改性或復(fù)合處理技術(shù)，改變模具表面的形態(tài)、化學(xué)成分、組織結(jié)構(gòu)和應(yīng)力狀態(tài)，以獲得所需表面性能的系統(tǒng)工程。從表面處理的方式上，又可分為：化學(xué)方法、物理方法、物理化學(xué)方法和機(jī)械方法。雖然旨在提高模具表面性能新的處理技術(shù)不斷涌現(xiàn)，但在模具制造中應(yīng)用較多的主要是滲氮、滲碳和硬化膜沉積。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="內(nèi)蒙古口碑好閥門模具國家標(biāo)準(zhǔn)"

style="text-indent:25px">從閥門零件的工藝安排上講，閥門的主要零件個數(shù)不多，結(jié)構(gòu)相對簡單，大部分尺寸的加工精度不高，外部比較粗糙，這就給人一種屬于簡單機(jī)械的印象。其實閥門的心臟密封部位可是精密，其密封面要求很高，平整度、光潔度、硬度，以及兩個密封面形成的密封付的吻合度都有達(dá)到零對零，才能滿足氣體密封試驗的零泄漏。這種以粗糙的基準(zhǔn)來保證精密的零對零要求，就是閥門加工的大工藝難點。從閥門的試驗和檢驗上講，閥門是壓力管道重要的啟閉、調(diào)節(jié)元件，而壓力管道的使用工況是千變?nèi)f化的，高溫高壓、低溫深冷、易燃易爆、劇毒強(qiáng)腐蝕。</p></p><br
