一、H72TC陶瓷對夾式止回閥簡介
         H72TC陶瓷對夾式止回閥又稱陶瓷單向閥或陶瓷逆止閥，其作用是防止管路中的介質(zhì)倒流。水泵吸水關(guān)的底閥也屬于止回閥類。 啟閉件靠介質(zhì)流動和力量自行開啟或關(guān)閉，以防止介質(zhì)倒流的閥門叫陶瓷止回閥。
二、用途：
該系列閥門使用于電廠干灰系統(tǒng)倉泵的進(jìn)出料門，也可用于礦山、化工等各類有磨損的干灰、水渣等介質(zhì)管道的止回裝置。
本閥門閉后任何方向全部密封。閥體閥蓋采用WCB鑄鋼件或不銹鋼鑄件。密封面采用硬密封件。
本閥料口耐磨性能強，密封性能好，啟動負(fù)荷小，卡灰及結(jié)灰現(xiàn)象少。
本閥采用高檔增韌結(jié)構(gòu)陶瓷密封，機械強度高，耐磨性能好，使用壽命長。結(jié)構(gòu)緊湊可任意角度安裝。
三、特點：
閥辨與閥座均采用高性能結(jié)構(gòu)增韌陶瓷制造。
該品為手行式閘板結(jié)構(gòu)。密封可靠、啟閉輕便、維修方便。
本品具有高耐磨、耐沖刷等特點。
適用于水管道安裝。
四、主要參數(shù)：
公稱壓力：1.0MPa-1.6MPa
公稱通經(jīng)：DN15-DN1500
適用溫度：-40°C+797°F
連接形式：對夾式
