加工比較方便2、凹凸式：工作壓力較高，可使用中硬墊圈3、榫槽式：可用塑性變形較大的墊圈，在腐蝕性介質(zhì)中使用較***，密封效果較好。4、梯形槽式：用橢圓形金屬環(huán)作墊圈，使用于工作壓力≥64公斤/平方厘米的閥門，或高溫閥門。5、透鏡式：墊圈是透鏡形狀，用金屬制作。用于工作壓力≥100公斤/平方厘米的高壓閥門，或高溫閥門。6、O形圈式：這是一種較新的法蘭連接形式，它是隨著各種橡膠O形圈的出現(xiàn)，而發(fā)展起來的，它在密封效連接形式。閥門對(duì)夾連接用螺栓直接將閥門及兩頭管道穿夾在一起的連接形式。閥門對(duì)焊連接直接與管道焊接的一種連接方式。閥門螺紋連接這是一種簡(jiǎn)便的連接方法，常用于小閥門。又分兩種情況：1、直接密封：內(nèi)外螺紋直接起密封作用。為了確保連接處不漏，往往用鉛油、線麻和聚四氟乙烯生料帶填充；其中聚四氟乙烯生料帶，使用日見***；這種材料耐腐蝕性能很好，密封效果較好，使用和保存方便，拆卸時(shí)，可以完整地將其取下，因?yàn)樗且粚訜o粘性的薄膜，比鉛油、線麻優(yōu)越得多。2、間接密封：螺紋旋緊的力量，傳遞給兩平面間的墊圈，讓墊圈起密封作用。閥門卡套連接卡套連接，它的連接和密封原理是，當(dāng)旋緊螺母時(shí)，卡套受到壓力，使其刃部咬入管子外壁。</p><div
