style="text-indent:25px">閥門銅配件銅閥桿與填料接觸的表面經(jīng)常受到腐蝕。這種腐蝕常發(fā)生在使用前的貯存階段，這是由于經(jīng)過(guò)水壓試驗(yàn)后的填料被水飽和的緣故。如果在水壓試驗(yàn)后立即投入使用就不會(huì)發(fā)生腐蝕。從理論上講，處于濕潤(rùn)填料之中的銅閥桿其所以被腐蝕，是由于被填料所包圍的閥桿表面處在脫氧環(huán)境之中的結(jié)果。這種環(huán)境影響了金屬的活化與鈍化特性。銅氧化保護(hù)層表面的缺氧敏感點(diǎn)上產(chǎn)生了許多小的陽(yáng)極，這些陽(yáng)極與發(fā)生陽(yáng)極作用的大量殘留的鈍性金屬一起，就使金屬內(nèi)部產(chǎn)生原電池的作用。通常用于填料中的石墨作為陽(yáng)極材料作用于閥桿鋼的陰極場(chǎng)增強(qiáng)了原電池電流強(qiáng)度，從而很大程度加劇了對(duì)原始腐蝕點(diǎn)的腐蝕。閥門銅配件閥座有對(duì)夾式閥座和法蘭式閥座兩種。河北小閥門銅配件</p><p
