O型圈的材料主要有丁氰橡膠NBR和氟橡膠FKM，氟橡膠更適用于高溫工況。除材料之外，O型圈很重要的一個指標(biāo)的是它的硬度，一般采用邵氏硬度來表示，從60到90左右不等，數(shù)值越大表示硬度越高。在同樣壓力下，硬度越高，防擠出(變形甚至撕裂)的能力就越強。因此，應(yīng)選用硬度較高的O型圈。然而，市場上常見的O型圈均為丁氰橡膠制成，邵氏硬度一般O型圈的溝槽設(shè)計有相關(guān)的國家標(biāo)準(zhǔn)，主要分動密封、軸向靜密封和徑向靜密封三種。法蘭、箱蓋等的O型圈采用軸向壓緊更便于裝配和保證密封性能。另外，我國國家標(biāo)準(zhǔn)中的溝槽尺寸標(biāo)準(zhǔn)已顯落后，如國家標(biāo)準(zhǔn)中受內(nèi)壓的O型圈溝槽外徑等于O型圈外徑，而PARKER法蘭接頭的O型圈溝槽外徑小于O型圈外徑。設(shè)計時應(yīng)適當(dāng)參考國外標(biāo)準(zhǔn)。在70左右，難以滿足相當(dāng)一部分工況的要求。有O型圈的密封面不得使用平面密封膠，可以在O型圈上涂少量黃油以使其不脫落。在維修時。江西耐高溫O型圈廠家耐高溫o型圈_專業(yè)生產(chǎn)廠家。</p><div
