style="text-indent:25px">手動(dòng)閥門是設(shè)備和裝置上使用很普遍的一種閥門，它是通過手柄、手輪來操作的。一般情況下手柄、手輪順時(shí)針旋轉(zhuǎn)規(guī)定為關(guān)閉方向，逆時(shí)針旋轉(zhuǎn)規(guī)定為開啟方向。但有的閥門啟閉方向與上述相反，故操作前應(yīng)注意檢查啟閉標(biāo)志后再操作。手動(dòng)閥門，其手柄、手輪的大小是按正常人力設(shè)計(jì)的。因此，在手動(dòng)閥門使用上規(guī)定：不允許操作者借助杠桿和長(zhǎng)扳手啟、閉閥門。同時(shí)，手柄長(zhǎng)度、手輪直徑小于320mm的，只允許一個(gè)人操作；直徑等于或超過320mm的手輪，允許兩人共同操作，或者允許一人借助適當(dāng)?shù)母軛U(一般長(zhǎng)度不超過0．5m)操作。但隔膜閥、非金屬閥門是嚴(yán)禁使用杠桿或長(zhǎng)扳手操作的，手動(dòng)蝶閥規(guī)格，也不允許用過大、過猛的力關(guān)閉閥門，手動(dòng)蝶閥規(guī)格。閥門型號(hào)的標(biāo)準(zhǔn)化對(duì)閥門的設(shè)計(jì)，手動(dòng)蝶閥規(guī)格、選用、銷售提供了方便。手動(dòng)蝶閥規(guī)格</p><div

style="text-indent:25px">手動(dòng)閥門的磨粒磨損這是粗糙的硬表面在軟表面上滑動(dòng)時(shí)出現(xiàn)的磨損。硬材料壓入較軟的材料表面，在軟表面上滑動(dòng)時(shí)出現(xiàn)的磨損。硬材料壓入較軟的材料表面，在接觸的表面就會(huì)劃出一條微小的溝槽。此溝槽所脫落的材料，以碎屑或疏松粒子的形式被推離物體表面。磨蝕磨損金屬表面腐蝕時(shí)，產(chǎn)生一層氧化物。這層氧化物通常覆蓋在受到腐蝕作用的部位上，這樣就能減慢對(duì)金屬的進(jìn)一步腐蝕。但是，如果發(fā)生滑動(dòng)的話，就會(huì)去除掉表面的氧化物，使裸露出來的金屬表面受到進(jìn)一步的腐蝕。手動(dòng)閥門表面疲勞磨損反復(fù)循環(huán)加載和卸載，會(huì)使表面或表面下層產(chǎn)生疲勞裂紋，在表面形成碎片和凹坑，導(dǎo)致表面破壞。沖蝕材料損壞是由銳利的粒子沖擊物體表面產(chǎn)生的。它與磨粒磨損相似，但表面很粗糙。手動(dòng)閥門的擦傷是指密封面相對(duì)運(yùn)動(dòng)的過程中，材料因摩擦引起的破損。</p><p
