style="font-size:16px;">蝶閥的選用原則1、由于蝶閥相對(duì)于閘閥，球閥壓力損失比較大，故適應(yīng)于壓力損失要求不嚴(yán)的管路系統(tǒng)中2、由于蝶閥可以用流量調(diào)節(jié)，故在需要進(jìn)行流量調(diào)節(jié)的管路中宜于選用3、由于蝶閥的結(jié)構(gòu)和密封材料的限制，不宜用于高溫，高壓的管路系統(tǒng)。一般工作溫度在300℃以下，公稱壓力在PN40以下。4、由于蝶閥結(jié)構(gòu)長(zhǎng)度比較短，且又可以做成大口徑，故在結(jié)構(gòu)長(zhǎng)度要求短的場(chǎng)合或是大口徑閥門(mén)（如DN1000以上），宜選用蝶閥。5、由于蝶閥*旋轉(zhuǎn)90°就能開(kāi)啟或關(guān)閉，因此在啟閉要求快的場(chǎng)合宜選用蝶閥蝶閥***用于℃的各種介質(zhì)。閥桿只做旋轉(zhuǎn)運(yùn)動(dòng)，蝶板和</span><span

style="font-size:16px;">蝶閥于閘閥的使用區(qū)別在哪里？按照閘閥和蝶閥的作用及用途來(lái)說(shuō)，閘閥流阻小，密封性能好，因閘閥閥板和介質(zhì)流向是垂直角度，如果閘閥在閥板開(kāi)關(guān)不到位，介質(zhì)對(duì)閥板的沖刷使閥板顫動(dòng)，極易照成閘閥密封損壞。蝶閥又叫翻板閥，是一種結(jié)構(gòu)簡(jiǎn)單的調(diào)節(jié)閥，可用于低壓管道介質(zhì)的開(kāi)關(guān)控制的蝶閥是指關(guān)閉件（閥瓣或蝶板）為圓盤(pán)，圍繞閥軸旋轉(zhuǎn)來(lái)達(dá)到開(kāi)啟與關(guān)閉的一種閥，閥門(mén)可用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動(dòng)。在管道上主要起切斷和節(jié)流作用。蝶閥啟閉件是一個(gè)圓盤(pán)形的蝶板，在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn)，從而達(dá)到啟閉或調(diào)節(jié)的目的。蝶板由閥桿帶動(dòng)，若轉(zhuǎn)過(guò)90°，便能完成一次啟閉。改變蝶板的偏轉(zhuǎn)角度，即可控制介質(zhì)的流量。</span> </p><p> <span style="font-size:16px;">對(duì)建筑里常用的軟密封蝶閥來(lái)說(shuō)，它的三種連接形式比較大的差異是價(jià)格方面，從對(duì)夾，支耳，法蘭逐步提高的。其次是性能方面。在選擇使用的螺栓時(shí)，對(duì)夾連接是采用雙頭螺栓將蝶閥閥體固定在管道的法蘭中間，而法蘭連接則需要一對(duì)螺栓分別將蝶閥的兩片法蘭固定在管道法蘭中間。支耳蝶閥是比較特殊的一種，它有兩種連接孔，一個(gè)是貫穿孔，這種形式和對(duì)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(guò)程中，相當(dāng)于起到了兩個(gè)螺母的功能，用兩個(gè)螺栓分別固定在管道法蘭中間。大口徑蝶閥能不能夾的住的問(wèn)題。實(shí)際上對(duì)夾蝶閥的重量相比是較輕的，靠管道的夾持力是足以保證蝶閥牢固的安裝在管道中間，也不需要專門(mén)的做支撐。因此在非必要工況下，其造價(jià)低，安裝方便等優(yōu)點(diǎn)，是建議使用的。</span>

style="font-size:16px;">蝶閥是指啟閉件(蝶板)由閥桿帶動(dòng)，并繞閥桿的軸線作旋轉(zhuǎn)運(yùn)動(dòng)的閥門(mén)。蝶閥的特點(diǎn)是體積小，質(zhì)量輕、結(jié)構(gòu)簡(jiǎn)單，啟閉迅速、密封和調(diào)節(jié)性能良好，且可實(shí)現(xiàn)分級(jí)流量控制、流阻和操作力矩較小、由于蝶板的運(yùn)動(dòng)帶有擦拭性，故大多數(shù)蝶閥可用于帶懸浮固體顆粒介質(zhì)。蝶閥的種類很多，根據(jù)其結(jié)構(gòu)特點(diǎn)和用途，一般可分為兩大類：密封型蝶閥和非密封蝶閥。密封型蝶閥在關(guān)閉時(shí)能夠完全保證密封，在管路中可以作為切斷用;非密封型蝶閥在關(guān)閉時(shí)不能保證完全密封，只能在管道中做調(diào)節(jié)用或在密封要求不嚴(yán)的管道中使用。蝶閥和通道的連接方式有：對(duì)夾式、雙法蘭式、和單法蘭式。選用蝶閥應(yīng)遵循的原則：⑴與閘閥、截止閥、球閥、旋塞閥等相比，蝶閥的結(jié)構(gòu)尺寸**小，重量**輕，價(jià)格便宜，故對(duì)于大尺寸管道。</span> 蝶閥在完全開(kāi)啟時(shí)，具有較小的流阻。金昌蝶閥廠家</p><p style="text-indent:25px">蝶閥在管路中的壓力損失比較**約是閘閥的三倍。隴南蝶閥電話</p><p> <span
