style="text-indent:25px">如果要求蝶閥作為流量控制使用，主要的是正確選擇閥門的尺寸和類型。蝶閥的結構原理尤其適合制作大口徑閥門。蝶閥不僅在石油、煤氣，上海排氣閥配球閥生產企業(yè)、化工、水處理等一般工業(yè)上得到普遍應用，而且還應用于熱電站的冷卻水系統(tǒng)；蝶閥有彈性密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈可以鑲嵌在閥體上或附在蝶板周邊；常用的蝶閥有對夾式蝶閥和法蘭式蝶閥兩種，上海排氣閥配球閥生產企業(yè)，上海排氣閥配球閥生產企業(yè)。對夾式蝶閥是用雙頭螺栓將閥門連接在兩管道法蘭之間，法蘭式蝶閥是閥門上帶有法蘭，用螺栓將閥門上兩端法蘭連接在管道法蘭上。手動閥門的流線形設計，使流體阻力損失小，可謂是一種節(jié)能型產品。上海排氣閥配球閥生產企業(yè)</p><div
