6、銅合金銅合金常用材料有6-6-3錫青銅和58-2-2錳黃銅等。銅合金耐磨性好，適用于溫度t≤200℃、公稱壓力PN≤，常用于閘閥、截止閥、止回閥、旋塞閥等。7、鉻不銹鋼鉻不銹鋼常用牌號有2Cr13、3Cr13經(jīng)調(diào)質(zhì)處理，耐腐蝕性能好。常用于溫度t≤450℃，天津FSA真空管道蝶閥密封、公稱壓力PN≤32MPa的水，天津FSA真空管道蝶閥密封、蒸汽和石油等介質(zhì)的閥門上。8、鉻鎳鈦不銹鋼鉻鎳鈦不銹鋼常用牌號為1Cr18Ni9ti，其耐腐性、耐沖蝕性和耐熱性能較好，天津FSA真空管道蝶閥密封。適用于溫度t≤600℃、公稱壓力PN≤、硝酸等介質(zhì)中，用于截止閥、球閥等。9、滲氮鋼滲氮鋼常用牌號是38CrMoAlA，經(jīng)滲碳處理，具有良好的耐腐蝕性和抗擦傷性。常用于溫度t≤540℃、公稱壓力PN≤10MPa的電站閘閥。10、滲硼滲硼由閥體或閥瓣本體材料直接加工出密封面，再進行滲硼表面處理，密封面耐磨性能很好。用于電站排污閥。閥門在使用中，應(yīng)該注意的事項如：1、應(yīng)對閥門的密封性能進行試驗，確保其性能。2、應(yīng)查看閥門密封面是否磨損，并根據(jù)情況進行維修或更換。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="天津FSA真空管道蝶閥密封"

蝶閥的蝶板安裝于管道的直徑方向。在蝶閥閥體圓柱形通道內(nèi)，圓盤形蝶板繞著軸線旋轉(zhuǎn)，旋轉(zhuǎn)角度為0°~90°之間，旋轉(zhuǎn)到90°時，閥門則牌全開狀態(tài)。 </p> <p> <br /> </p> <p> 蝶閥結(jié)構(gòu)簡單、體積小、重量輕，只由少數(shù)幾個零件組成。而且只需旋轉(zhuǎn)90°即可快速啟閉，操作簡單，同時該閥門具有良好的流體控制特性。蝶閥處于完全開啟位置時，蝶板厚度是介質(zhì)流經(jīng)閥體時***的阻力，因此通過該閥門所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。蝶閥有彈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。 </p> <p> <br /> </p> <p> 采用金屬密封的閥門一般比彈性密封的閥門壽命長，但很難做到完全密封。金屬密封能適應(yīng)較高的工作溫度，彈性密封則具有受溫度限制的缺點。 </p> <p> <br /> </p> <p> 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(jié)構(gòu)原理尤其適合制作大口徑閥門。蝶閥不僅在石油、煤氣、化工、水處理等一般工業(yè)上得到廣泛應(yīng)用，而且還應(yīng)用于熱電站的冷卻水系統(tǒng)。 </p> <p> <br /> </p> <p> 常用的蝶閥有對夾式蝶閥和法蘭式蝶閥兩種。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。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="天津FSA真空管道蝶閥密封"

</p> <p> 2）檢查標準組合時，要考慮閥門所規(guī)定的允許壓差是否滿足工藝要求。大壓差時要計算閥芯所受的不平衡力。 </p> <p> 3）要考慮執(zhí)行機構(gòu)的響應(yīng)速度是否滿足工藝操作要求，尤其是電動執(zhí)行機構(gòu)。 </p> <p> <br /> </p> <p> 二、與氣動執(zhí)行機構(gòu)相比電動執(zhí)行機構(gòu)有何特點，有哪幾種輸出形式 </p> <p> <br /> </p> <p> 電動驅(qū)動源為電力簡單方便，推力、扭矩大，剛度大。但結(jié)構(gòu)復(fù)雜，可靠性差。在中小規(guī)格上比氣動的貴。常用于無氣源或不需嚴格防爆、防燃的場合。 </p> <p> <br /> </p> <p> 三、為什么角行程類閥的切斷壓差較大？ </p> <p> <br /> </p> <p> 角行程類閥的切斷壓差較大，是因為介質(zhì)在閥芯或閥板上產(chǎn)生的合力對轉(zhuǎn)動軸產(chǎn)生的力矩非常小，因此，它能承受較大的壓差。 </p> <p> 蝶閥，球閥是最常見的角行程類閥門。 </p> <p> <br /> </p> <p> 四、哪些閥需進行流向選擇？如何選擇？ </p> <p> <br /> </p> <p> 流開、流閉各有利弊。流開型的閥工作比較穩(wěn)定，但自潔性能和密封性較差，壽命短；流閉型的閥壽命長，自潔性能和密封性好，但當閥桿直徑小于閥芯直徑時穩(wěn)定性差。 </p> <p> <br /> </p> <p> <br /> </p> <p> 五、除單、雙座閥及套筒閥外還有哪些具有調(diào)節(jié)功能的閥？ </p> <p> <br /> </p> <p> 隔膜閥、蝶閥、O型球閥（以切斷為主）、V型球閥（調(diào)節(jié)比大、具剪切作用）、偏心旋轉(zhuǎn)閥都是具有調(diào)節(jié)功能的閥。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
