style="text-indent:25px">內自緊連接以上各種連接形式，都是利用外力來抵消介質壓力，實現(xiàn)密封的。下面介紹利用介質壓力進行自緊的連接形式。它的密封圈裝在內錐體處，跟介質相向的一面成一定角度，介質壓力傳給內錐體，又傳遞給密封圈，在一定角度的錐面上，產生兩個分力，一個與閥體中心線平行向外，另一個壓向閥體內壁。后面這個分力便是自緊力。介質壓力愈大，自緊力也愈大。所以這種連接形式，適合于高壓閥門。它比法蘭連接，要節(jié)省許多材料和人力，但也需要一定的預緊力，以便在閥內壓力不高時，使用可靠。利用自緊密封原理做成的閥門，一般是高壓閥門。閥門連接的形式還很多，例如有的不必拆除的小閥門，跟管子焊接在一起；有的非金屬閥門，采用承插式連接，等等。閥門使用者要根據(jù)具休情況具體對待。新疆疏水閥廠家直銷</p><p
