1、閥體結(jié)構(gòu)有單座、套筒、雙座（二位三通）三種，密封形式有填料密封和波紋管密封兩種，產(chǎn)品公稱壓力等級(jí)有PN10、16、40、64四種，公稱口徑范圍DN20～200mm。適用流體溫度由-60～450℃。泄漏量等級(jí)為IV級(jí)或Ⅵ級(jí)。流量特性為快開(kāi)；2、采用多彈簧執(zhí)行機(jī)構(gòu)與調(diào)節(jié)機(jī)構(gòu)用三根立柱相連，整個(gè)高度可減小約30%，重量可減輕約30%；3、閥體按流體力學(xué)原理設(shè)計(jì)成等截面低流阻流道，額定流量系數(shù)增大30%；4、閥內(nèi)件密封部分有嚴(yán)密型和軟密封兩種，嚴(yán)密型為堆焊硬質(zhì)合金，軟密封型為軟質(zhì)材料制作，關(guān)閉時(shí)密封性能優(yōu)良；5、平衡型閥內(nèi)件，提高了切斷閥的許用壓差；6、波紋管密封型對(duì)移動(dòng)的閥桿形成完全的密封，堵絕了介質(zhì)外漏的可能性；7、活塞式執(zhí)行機(jī)構(gòu)，操作力大，使用壓差大。 </p><p> 接頭尺寸至少為3/4英寸。當(dāng)容器接頭是法蘭式管嘴并且切斷閥直接安裝在管嘴上時(shí)，接頭**小尺寸為1英寸。當(dāng)容器接頭是管接頭且切斷閥安裝在一個(gè)短節(jié)上時(shí)，接頭的**小尺寸為3/4英寸，(除下述提到的例外情況外)。容器和切斷閥之間的配件或管道要減至**低限度。折疊編輯本段例外情況1.特殊應(yīng)用如果容器的管嘴是法蘭式的并且被連接的儀表(如差壓計(jì))是小尺寸的螺紋接頭，這時(shí)切斷閥**小可用3/4英寸的口徑并可以用一個(gè)縮徑法蘭和短節(jié)連接到容器管嘴上。2.雙切斷閥有些公司允許在并聯(lián)的儀表上采用雙切斷閥，這些儀表用直接裝在管嘴上的三通連接起來(lái)。這種方法可以節(jié)省空間并在很多情況下比較經(jīng)濟(jì)。3.法蘭式安裝的薄膜液位變送器這種型式的儀表安裝可設(shè)計(jì)成與容器壁齊平，變送器可用與法蘭同樣大小的切斷閥安裝在容器管嘴和變送器之間。折疊編輯本段用途切斷閥的用途很廣，可用于切斷煤氣、助燃空氣、冷風(fēng)及煙氣。煤氣切斷閥是把燃燒器與煤氣管道切斷。助燃空氣切斷閥是將燃燒器與助燃空氣管道切斷。熱風(fēng)爐在送風(fēng)期用燃燒器切斷閥將熱風(fēng)爐與燃燒器或煤氣系統(tǒng)及助燃空氣系統(tǒng)隔斷。煙道閥使熱風(fēng)爐與煙道隔離。冷風(fēng)閥的用途是在熱風(fēng)爐燃燒期把冷風(fēng)管道與熱風(fēng)爐隔開(kāi)。F系列切斷閥

結(jié)構(gòu)型式在切斷效果方面，角行程閥比直行程閥（如單座閥、套筒閥、閘閥等）結(jié)構(gòu)更簡(jiǎn)單、密封效果更可靠、更具有優(yōu)越性。比較有**性的有三偏心硬密封蝶閥、球閥等。密封面面對(duì)面密封常見(jiàn)的柱塞閥芯，其密封面為60°的小錐面，此小錐面的寬度通常在～2mm之間，要密封好就必須保證兩個(gè)錐面良好接觸。但事實(shí)上，它始終受到加工誤差的影響（如同心度、不圓度、傾斜度等），其密封效果不很理想。這類閥的泄漏率通常為10-4，經(jīng)精密研磨后可達(dá)到10-6，可達(dá)較高的密封等級(jí)。球面密封利用球面的球面轉(zhuǎn)動(dòng)與固定的閥定小錐面相切，它們之間為線接觸，這就比上述面對(duì)面密封效果好。球閥、球面密封蝶閥等就是采用這一思路來(lái)制作的，其泄漏率可達(dá)10-6～10-8，高性能的三偏心蝶閥可達(dá)10-8，甚至為零泄漏。
