style="font-size:16px;">在連接方式方面，常見有對夾，支耳，法蘭，其中對夾方式在建筑樓宇領(lǐng)域，應(yīng)用比較多，性價比較高。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。支耳式蝶閥有兩種連接孔，一種是貫穿孔，這種形式和對夾連接的一樣需要雙頭螺栓固定。另外一種就是螺紋孔，在連接過程中，相當于起到了兩個螺母的功能，用兩個螺栓分別固定在管道法蘭中間。在閥體材質(zhì)方面，大約是兩類，鑄鐵和鑄鋼。其中鑄鐵如果沒有特指球墨鑄鐵，就是用灰鑄鐵。鑄鋼也是一樣，不特指不銹鋼的話通常就是用碳鋼。在密封方面，分軟密封和硬密封兩種，樓宇內(nèi)用比較多的就是軟密封，材質(zhì)多為EPDM或者NBR。</span>

style="font-size:16px;">蘭州閥門廠家為您介紹蝶閥的特點：（1）結(jié)構(gòu)簡單，外形尺寸小，結(jié)構(gòu)長度短，體積小，重量輕，適用于大口徑的閥門。（2）全開時閥座通道有效流通面積較大，流體阻力較小。（3）啟閉方便迅速，調(diào)節(jié)性能好。（4）啟閉力矩較小，由于轉(zhuǎn)軸兩側(cè)蝶板受介質(zhì)作用基本相等，而產(chǎn)生轉(zhuǎn)矩的方向相反，因而啟閉較省力。（5）密封面材料一般采用橡膠、塑料、故低壓密封性能好流體直流通過，阻力降小、開啟方便、迅速。旋塞閥在管路中主要用作切斷、分配和改變介質(zhì)流動方向的。旋塞閥是歷史上早被人們采用的閥件。由于結(jié)構(gòu)簡單，開閉迅速（塞子旋轉(zhuǎn)四分之一圈就能完成開閉動作），操作方便，流體阻力小，至今仍被使用。目前主要用于低壓，小口徑和介質(zhì)溫度不高的情況下。</span>
