style="text-indent:25px">內(nèi)自緊連接以上各種連接形式，都是利用外力來(lái)抵消介質(zhì)壓力，實(shí)現(xiàn)密封的。下面介紹利用介質(zhì)壓力進(jìn)行自緊的連接形式。它的密封圈裝在內(nèi)錐體處，跟介質(zhì)相向的一面成一定角度，介質(zhì)壓力傳給內(nèi)錐體，又傳遞給密封圈，在一定角度的錐面上，產(chǎn)生兩個(gè)分力，一個(gè)與閥體中心線平行向外，另一個(gè)壓向閥體內(nèi)壁。后面這個(gè)分力便是自緊力。介質(zhì)壓力愈大，自緊力也愈大。所以這種連接形式，適合于高壓閥門(mén)。它比法蘭連接，要節(jié)省許多材料和人力，但也需要一定的預(yù)緊力，以便在閥內(nèi)壓力不高時(shí)，使用可靠。利用自緊密封原理做成的閥門(mén)，一般是高壓閥門(mén)。閥門(mén)連接的形式還很多，例如有的不必拆除的小閥門(mén)，跟管子焊接在一起；有的非金屬閥門(mén)，采用承插式連接，等等。閥門(mén)使用者要根據(jù)具休情況具體對(duì)待。烏魯木齊市工業(yè)管道閥門(mén)廠家推薦。</p><div
