style="text-indent:25px">密封性能和強(qiáng)度性能是一切通風(fēng)閥門基本、比較重要的性能。通風(fēng)閥門的密封分內(nèi)密封和外密封兩部分。內(nèi)密封是閥瓣與閥座之間的密封；外密封是閥桿運(yùn)動(dòng)部位與閥蓋之間、閥體與閥蓋之間和閥體與管道聯(lián)接部位之間的密封。通風(fēng)閥門在使用時(shí)不僅要求密封性能好，而且必須保證安全。如果因密封不好而發(fā)生泄漏或因強(qiáng)度不夠而使零件破壞，將會(huì)造成不同程度的經(jīng)濟(jì)損失，如輸送有毒，上海通風(fēng)手動(dòng)蝶閥、易燃易爆或有強(qiáng)腐蝕性流體，還可能導(dǎo)致嚴(yán)重的安全事故。為了保證閥門的密封和強(qiáng)度，上海通風(fēng)手動(dòng)蝶閥，除了必須遵守有關(guān)標(biāo)準(zhǔn)規(guī)定合理地進(jìn)行結(jié)構(gòu)設(shè)計(jì)、確保工藝質(zhì)量外，還必須正確地選用材料，上海通風(fēng)手動(dòng)蝶閥?？ㄌ走B接形式，已在中國(guó)某些小口徑通風(fēng)閥門產(chǎn)品中采用。上海通風(fēng)手動(dòng)蝶閥</p><div

style="text-indent:25px">通風(fēng)閥門的基本參數(shù)是工作壓力、工作溫度和口徑。對(duì)于大量使用于工業(yè)管道的各種閥門，常用公稱壓力和公稱通徑作為基本參數(shù)。公稱壓力是指某種材料的閥門，在規(guī)定的溫度下，允許承受的較大工作壓力。公稱通徑是指閥體與管子聯(lián)接端部的名義內(nèi)徑。通風(fēng)閥門根據(jù)其種類和用途有不同的要求，主要有密封、強(qiáng)度、調(diào)節(jié)、流通、啟閉等性能。在設(shè)計(jì)和選用閥門時(shí)，除了要考慮基本參數(shù)和性能外，還要考慮流體的性能，包括流體的相態(tài)(氣體、液體或含固體顆粒)、腐蝕性、粘度、毒性、易燃易爆性，貴重稀有程度和放射性等。上海通風(fēng)手動(dòng)蝶閥通風(fēng)閥門注脂時(shí)，注意閥門在開(kāi)關(guān)位的問(wèn)題。球閥維護(hù)保養(yǎng)時(shí)一般都處于開(kāi)位狀態(tài)，特殊情況下選擇關(guān)閉保養(yǎng)。</p><div
