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。徑向壓力沿整個填料長度按指數(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)整到允許末一個圈填料稍有一點泄漏,也就是說這個環(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,則大多數(shù)填料圈上就將出現(xiàn)一些泄漏。</span>

style="font-size:16px;">閥門關(guān)閉，對于燃氣總閥門來說，并不需要每次使用完都關(guān)閉，每次使用后記得關(guān)閉小的閥門就足夠了，總閥門也就是大閥門在一些長時間外出或者是長時間不用燃氣的時候關(guān)閉就可以了，經(jīng)常的關(guān)閉這個閥門容易壞。小的閥門應(yīng)該記住使用順序，先開小閥門然后再打開燃氣灶開關(guān)，關(guān)閉的時候也是要先關(guān)閉燃氣灶開關(guān)，然后再去關(guān)閉小閥門，避免因為先關(guān)閥門造成的火苗倒吸進管道，導(dǎo)致管道著火。順序一定不要弄混，很多老年人一直是按照自己的習(xí)慣來，習(xí)慣很可能是錯的，所以子女記得要和家中的老人講明白應(yīng)該怎么做。閥門在流體系統(tǒng)中，是用來控制流體的方向、壓力、流量的裝置。在施工過程中，閥門安裝的質(zhì)量，直接影響到日后的正常運行，所以必須引起施工單位及生產(chǎn)單位的高度重視。</span>
