style="font-size:16px;">繞成螺旋狀的或者作為切制圖,裝在壓蓋上的成型件。無論采用哪種結(jié)構(gòu),都是靠壓緊壓蓋,迫使填料緊壓在密封表面上而取得密封作用的。由于壓緊壓蓋所形成的壓緊力產(chǎn)生一種造成密封效果的徑向壓力。徑向壓力沿整個(gè)填料長(zhǎng)度按指數(shù)曲線分布。為了保持填料的“干”狀態(tài),內(nèi)側(cè)圈上的徑向壓力至少要等于系統(tǒng)的內(nèi)壓力,這就意味著外側(cè)圈上的徑向壓力高得多,在大多數(shù)用途中是過高的(導(dǎo)致過大的摩擦,軸磨損和氣動(dòng)密封件失效)。因此,在大多數(shù)使用中,要將壓緊力調(diào)整到允許末一個(gè)圈填料稍有一點(diǎn)泄漏,也就是說這個(gè)環(huán)上的徑向壓力稍微低于系統(tǒng)的內(nèi)壓力。然而,這樣一來,如果將壓蓋調(diào)整到不產(chǎn)生泄漏的小壓縮程度時(shí),則大多數(shù)填料圈上就將出現(xiàn)一些泄漏。</span>
