閥的修復(fù)方法及原理

(1)零件組合選配維修法。液壓閥制造過程中，為提高裝配精度多采用選配方法，即對一批加工完畢的零件，如閥體和閥芯。依據(jù)實(shí)際尺寸選擇配合間隙最為恰當(dāng)?shù)囊粚M(jìn)行裝配，以保證良好的閥芯滑動(dòng)和密封性能。也就是說，同一類型的液壓閥，閥芯與閥體的配合尺寸有一定的差異。

對于使用企業(yè)，當(dāng)某一種失效液壓閥的數(shù)量較多時(shí)，可以將所有閥拆卸清洗，檢查測量各零件，依據(jù)檢測結(jié)果將零件歸類，依據(jù)下列方法重新組合選配。

如果閥芯、閥體屬于均勻磨損，工作表面沒有嚴(yán)重劃傷或局部嚴(yán)重磨損，則依照有關(guān)手冊，選擇出具有合適間隙的閥芯、閥體重新裝配。如果閥芯、閥體磨損不均勻或工作表面有劃傷，通過上述方法已經(jīng)不能恢復(fù)液壓閥功能，則選擇滿足加工余量要求的過盈量的一對閥芯、閥體(孔尺寸小的閥體與外徑尺寸大的閥芯)，對閥體孔進(jìn)行鉸削或磨削，對閥芯進(jìn)行磨削，達(dá)到合理的形狀精度配合精度后裝配。

(2)恢復(fù)尺寸維修法。采用零件選配法維修液壓閥雖然工藝較為簡單，但有其局限性，而采用修理尺寸法則適應(yīng)更為廣泛的場合。簡易可行的修理尺寸法主要有更換零件法和修補(bǔ)法兩類。

更換零件法是將已經(jīng)失去配合精度的閥芯拆卸，測量并畫出零件圖，檢查閥體導(dǎo)向孔或閥座的磨損及損壞程度，并依此確定修復(fù)加工量，然后進(jìn)行精加工(精鉸或磨削)修復(fù)。對于有一定錐度的閥座，要制作特定的加工工具。加工到相應(yīng)精度后，測量實(shí)際尺寸，然后依據(jù)此尺寸加工新的閥芯。這種維修方法維修精度高，適應(yīng)面廣，可完全恢復(fù)原有的精度，適合于有一定加工能力的企業(yè)。
