O型圈作為往復(fù)式密封，結(jié)構(gòu)緊湊、尺寸小，可以降低元件價格。主要用在：1）低壓液壓元件中，一般限于短行程和10MPa左右的中等壓力。2）小直徑、短行程以及中等壓力的液壓滑閥中。3）氣動滑閥和氣動缸中。4）作為組合式往復(fù)動密封裝置中的彈性體。O型圈作為往復(fù)動密封適合小直徑，天津食品級O型圈、短行程、中低壓力的應(yīng)用場合，氣動缸、氣動滑閥等往復(fù)運動元件中。在液壓元件中，用O型圈作主要動密封，一般限于短行程和10MPa左右的中低壓力。O型圈不適合用作速度非常低的往復(fù)動密封和單獨作為高壓往復(fù)動密封。這主要是因為在這種條件下摩擦較大，會導致密封過早失效。在任何型式應(yīng)用中，都要根據(jù)密封件的額定數(shù)據(jù)或能力來使用，并且要裝配得當，才能得到滿意的性能。3、旋轉(zhuǎn)運動用密封在旋轉(zhuǎn)運動密封中，通常采用油封和機械密封。但是油封的使用壓力較低，而且與O型圈相比，顯得過大和復(fù)雜，工藝性也差。機械密封雖然可用于高壓（40MPa）、高速（50m/s）及高溫（400℃），但是結(jié)構(gòu)更加復(fù)雜、龐大，天津食品級O型圈，而且成本高，天津食品級O型圈，只適用于石油、化工等作用的一些重型機械設(shè)備上。

橡膠O型圈安裝要求(1)檢查引入角是否符合圖紙要求，15°~30°以及D2K尺寸。(2)密封件和零件應(yīng)涂潤滑脂或潤滑液，但不得使用含固體添加劑的潤滑脂，如二硫化鉬、硫化鋅。(3)安裝前對安裝軸頸進行外觀檢查，表面不得有飛邊毛刺、雜質(zhì)、灰塵等缺陷及刮傷。(4)安裝過程中防止O型圈碰傷，應(yīng)先用銼修平毛刺，在其通過的部位螺紋及鍵槽表面用膠帶包上再進行安裝，可起到保護O型圈的作用。油管接頭倒角密封橡膠O型圈是一種連接面處的密封，采用O形圈將其裝配到一個通過倒角產(chǎn)生的槽中，然后通過殼體擠壓來產(chǎn)生密封。設(shè)計時主要考慮橡膠O型圈產(chǎn)品必須進行輕微拉伸、壓縮量適當減小、填充率適當加大。倒角一般為15°~30°，依據(jù)工作壓力選取，壓力大時，角度要趨近于小值。反之，則取大值。倒角密封因其在接頭與液壓閥之間使用簡便，操作簡單，且制作與加工容易等特點，在油管接頭的密封過程中常被廣泛應(yīng)用。本文著重介紹密封倒角的設(shè)計及O型圈的選用。橡膠O型圈破壞的重要原因之一是在工作壓力作用下被擠入間隙內(nèi)，此間隙的允許值與工作壓力，橡膠O型圈橡膠硬度及其截面直徑d0大小有關(guān)，O型圈壓縮量的大小能直接影響到密封性能和使用壽命，壓縮量太小，密封效果不好;壓縮量太大。

性能指標1.分析項目：主成分分析、圖譜分析、失效分析、全成份分析、材質(zhì)鑒定、配方還原等2.物理機械性能：密度/比重、硬度試驗、表面電阻率、拉伸性能、沖擊性能等；3.老化性能：臭氧、紫外老化、鹽霧老化、氙燈老化、碳弧燈老化、鹵素燈老化、壽命推算等；4.耐液體性能：耐潤滑油、耐汽油、耐機油、耐酸、耐堿、耐有機溶劑、耐耐水性能等；5.燃燒性能：防火阻燃、垂直燃燒、酒精噴燈燃燒、巷道丙烷燃燒、煙密度、燃燒速率等；6.適用性能：耐液壓、脈沖試驗、導電性能、水密性、氣密性等。材料選擇用作O形圈的材料有丁腈橡膠、羧酸腈、氟橡膠、乙丙橡膠、氫化丁腈橡膠、硅橡膠、氯丁橡膠、氟硅橡膠、聚氨酯、氯醇橡膠、丁苯橡膠、丁基橡膠、天然橡膠、乙烯/乙丙酸橡膠、聚丙烯酸酯橡膠、全氟橡膠等等。同樣一種橡膠由于配方的不同，性能指標也有較大的變化。所以在材料欄中簡單地填寫丁腈橡膠或丁腈-40是不準確的。用于O形圈的材料化工部有專門的標準，如：HG/T2579-1994、HG/T2021-1991、HG/T2333-1992、HG/T3089-2001、HB5290-1991等。HG/T2579-1994專門去掉了材料的具體類別，只給出了材料的一些性能指標。進口O型圈-派克密封件美標AS568標準O-ring。</p><div

O型密封圈O型圈(O-rings)是一種截面為圓形的橡膠密封圈，因其截面為O型，故稱其為O型橡膠密封圈，也叫O型圈。開始出現(xiàn)在19世紀中葉，當時用它作蒸汽機汽缸的密封元件。O型圈，是一種圓環(huán)形狀的機械墊片，它是環(huán)狀的彈性體，斷面為圓形，一般會固定在一凹槽中，組裝過程中會被兩個或兩個以上的組件壓縮，因此產(chǎn)生密封的接口。因為價格便宜，制造簡單，功能可靠，并且安裝要求簡單，O型圈是常見的密封用機械設(shè)計。可以承受幾十帕斯卡（千磅）的壓力。O型圈可用于靜態(tài)的應(yīng)用中，也可以用在部件之間有相對運動的動態(tài)應(yīng)用中，例如旋轉(zhuǎn)泵的軸和液壓缸活塞。O型密封圈O型圈(O-rings)是一種截面為圓形的橡膠密封圈，因其截面為O型，故稱其為O型橡膠密封圈，也叫O型圈。開始出現(xiàn)在19世紀中葉，當時用它作蒸汽機汽缸的密封元件。天津食品級O型圈</p><p
