style="font-size:16px;">蝶閥是指啟閉件(蝶板)由閥桿帶動，并繞閥桿的軸線作旋轉(zhuǎn)運(yùn)動的閥門。蝶閥的特點(diǎn)是體積小，質(zhì)量輕、結(jié)構(gòu)簡單，啟閉迅速、密封和調(diào)節(jié)性能良好，沙坡頭區(qū)蝶閥聯(lián)系方式，且可實(shí)現(xiàn)分級流量控制、流阻和操作力矩較小、由于蝶板的運(yùn)動帶有擦拭性，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，沙坡頭區(qū)蝶閥聯(lián)系方式，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，故對于大尺寸管道。</span> ，沙坡頭區(qū)蝶閥聯(lián)系方式.蝶閥的結(jié)構(gòu)長度和總體高度較小，開啟和關(guān)閉速度較快。沙坡頭區(qū)蝶閥聯(lián)系方式</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="font-size:16px;">蝶閥是根據(jù)旋轉(zhuǎn)閥桿同時(shí)帶動蝶板轉(zhuǎn)動來做啟閉的一種閥門，在蝶閥閥體圓柱形通道內(nèi)，圓盤形蝶板繞著軸線旋轉(zhuǎn)，主要是旋轉(zhuǎn)蝶板90°來做流量控制，當(dāng)?shù)宓竭_(dá)90°時(shí)閥門處于全開狀態(tài)，同時(shí)可以改變蝶板的角度來調(diào)節(jié)介質(zhì)流量，一般安裝于管道的直徑方向。蝶閥與閥桿自身是沒有鎖定能力，為了有效的調(diào)節(jié)流量需裝蝸輪減速器，加裝蝸輪減速器的蝶閥不僅使蝶閥有自鎖能力，還能改變蝶閥的操作性能及更準(zhǔn)確的調(diào)節(jié)介質(zhì)流量。1、蝶閥在完全開啟時(shí)，具有較小的流阻。當(dāng)開啟在大約15°~70°之間時(shí)，又能進(jìn)行靈敏的流量控制，因而在大口徑的調(diào)節(jié)領(lǐng)域，蝶閥的應(yīng)用非常普遍。由于蝶閥蝶板的運(yùn)動帶有擦拭性，故大多數(shù)的蝶閥可用于帶懸浮固體顆粒的介質(zhì)。依據(jù)密封件的強(qiáng)度，也可用于粉狀和顆粒狀介質(zhì)。</span>

style="font-size:16px;">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，故對于大尺寸管道，用蝶閥代替其他切斷閥對降低裝置建設(shè)成本是非常有利的;⑵與閘閥、截止閥、球閥、旋塞閥等相比，其密封可靠性**差，故不宜用于高溫(如200℃及以上)、高壓(如Class600及以上)的介質(zhì)工況，但個(gè)別工廠的特殊設(shè)計(jì)例外;⑶對于軟密封蝶閥，雖然價(jià)格會更便宜，但受溫度和壓力的限制，高溫高壓時(shí)不能使用;⑷蝶閥無密閉閥腔，適宜用于低溫介質(zhì)工況或可能發(fā)生氣化的介質(zhì)工況;⑸不能用于有通球要求的管路切斷;⑹可以做襯里;⑺適宜用于壓力脈動介質(zhì)工況和可能產(chǎn)生汽蝕的介質(zhì)工況;適宜用于高壓氧氣工況;適宜用于可能產(chǎn)生沖刷或沖刷腐蝕的介質(zhì)工況;⑻相對于閘閥、球閥來說，由于蝶閥的壓</span><span
