style="text-indent:25px">在安裝手動蝶閥的時候，注意先看好管道上介質(zhì)流動的方向要與閥體所標(biāo)的箭頭方向一樣，同時還需要注意選擇好安裝的位置、高度和進出口的情況等，連接的部位一定要牢固而緊密了。對外觀進行相關(guān)的檢查，也是安裝前需要做的，并要做好壓力的測試等，在符合要求的規(guī)定范圍之內(nèi)就可以了。蝶閥的蝶板主要安裝于管道的半徑方向。在蝶閥閥體圓柱形通道里，圓盤形蝶板圍繞著軸線旋轉(zhuǎn)，旋轉(zhuǎn)角度為0°-90°之間，旋轉(zhuǎn)到90°時，閥門則排全開狀態(tài)。蝶閥結(jié)構(gòu)簡單、體積小、重量輕，只有幾個少數(shù)零件組成。且只需旋轉(zhuǎn)90°就可以快速啟閉，操作簡單，同時該閥門具有良好的流體控制特性。當(dāng)?shù)y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，所以通過該閥門所產(chǎn)生的壓力會降很小，故而具有較好的流量控制特性。上海不銹鋼高壓球閥手動閥門是管路流體輸送系統(tǒng)中控制部件，它是用來改變通路斷面和介質(zhì)流動方向。</p><div
