    O形圈屬于擠壓密封,擠壓型密封結(jié)構(gòu)的基本特點(diǎn)依靠密封件發(fā)生彈xing變形、在密封接觸面上造成接觸壓力,當(dāng)

    接觸壓力大于被密封介質(zhì)的內(nèi)壓時(shí),則起到密封作用,反之導(dǎo)致滲漏。兩片式球閥的左、右端體為金屬對(duì)金屬

    接觸,屬于靜態(tài)密封結(jié)構(gòu),為了減小或消除它們之間的密封面間隙,在設(shè)計(jì)時(shí)選擇O形圈作密封元件,當(dāng)介質(zhì)壓

    力較小時(shí)呈靜止?fàn)顟B(tài),所需密封力很小,此時(shí)靠裝配時(shí)的預(yù)緊力在O形圈彈力的作用下,即可保證左、右端體密

    封;當(dāng)介質(zhì)壓力不斷升高時(shí),密封比壓也隨著增大,O形圈驟然膨脹,此時(shí)O形圈有效地阻止了兩端縫隙間的泄

    漏點(diǎn),球閥的密封xing能因而得到保證產(chǎn)品SMK20-12L-VG-C6F入庫(kù)號(hào)產(chǎn)品SMK20-12L-VG-C6F入庫(kù)號(hào)

    當(dāng)球閥作啟、閉動(dòng)作時(shí),無(wú)論采用何種驅(qū)動(dòng)方式,閥桿都要作旋轉(zhuǎn)運(yùn)動(dòng),為防止介質(zhì)通過(guò)中孔間隙竄出,在閥

    桿處勾一凹槽嵌入O形圈雖然閥桿作往復(fù)轉(zhuǎn)動(dòng)90,但由于O形圈的摩擦小和良好的自潤(rùn)滑xing,它們相互

    配合起到良好的密封效果。為了保證閥座與閥芯形成良好的密封副,同樣在閥座內(nèi)加工一凹槽,把O形圈安裝

    其中(如圖4)當(dāng)閥腔介質(zhì)壓力升高時(shí),在彈huang力的推動(dòng)下,閥座向閥芯產(chǎn)生位移,在O形圈高彈xing能的作

    用下,保證了管道內(nèi)腔的密封xing,此時(shí)O形圈在管道中啟動(dòng)態(tài)密封效果,前兩種結(jié)構(gòu)形式中,O形圈同屬于動(dòng)
    態(tài)密封結(jié)構(gòu)。
