）防止閃蒸和空化

閃蒸和空化只產(chǎn)生在液體介質(zhì)。在實(shí)際生產(chǎn)過程中，閃蒸和空化會(huì)形成振動(dòng)和噪聲，縮短閥門的使用壽命，因此在選擇閥門時(shí)應(yīng)防止閥門產(chǎn)生閃蒸和空化。

1、中心密封蝶閥：

結(jié)構(gòu)特征為閥桿軸心、蝶板中心、本體中心在同一位置上。 結(jié)構(gòu)簡單、制造方便。常見的襯膠蝶閥即屬于此類。缺點(diǎn)是由于蝶板與閥座始終處 于擠壓、刮擦狀態(tài)、阻距大、磨損快。為克服擠壓、刮擦、保證密封性能、閥座基 本上采用橡膠或聚四氟乙烯等彈性材料、但也因而在使用上受到溫度的限 制、這就 是為什么傳統(tǒng)上人們認(rèn)為蝶閥不耐高溫的原因。
