手動閥：手動閥借助手輪、手柄、杠桿，江蘇信號蝶閥門便宜、鏈輪，由人力來操縱閥門動作。當(dāng)閥門啟閉力矩較大時，江蘇信號蝶閥門便宜，可在手輪和閥桿之間設(shè)置齒輪或蝸輪減速器，江蘇信號蝶閥門便宜。必要時，也可以利用萬向接頭及傳動軸進行遠距離操作。 </p><div style="width:100%;text-align: center;"><img style="max-width:

閥門的密封性能是指閥門各密封部位阻止介質(zhì)泄漏的能力，它是閥門**重要的技術(shù)性能指標(biāo)。閥門的密封部位有三處：啟閉件與閥座兩密封面間的接觸處；填料與閥桿和填料函的配合處；閥體與閥蓋的連接處。其中前一處的泄漏叫做內(nèi)漏，也就是通常所說的關(guān)不嚴，它將影響閥門截斷介質(zhì)的能力。對于截斷閥類來說，內(nèi)漏是不允許的。后兩處的泄漏叫做外漏，即介質(zhì)從閥內(nèi)泄漏到閥外。外漏會造成物料損失，污染環(huán)境，嚴重時還會造成惡事件。對于易燃易爆、或有放射的介質(zhì)，外漏更是不能允許的，因而閥門必須具有可靠的密封性能。
