產(chǎn)品結(jié)構(gòu)特點(diǎn)

Q647MF-16C/25氣動(dòng)噴煤粉球閥是作為控制含塵、含固體粉末，特別適用于高爐煤粉噴吹、空氣管路及噴槍管路等系統(tǒng)。
1、閥座帶有磨損自動(dòng)補(bǔ)償裝置，有效確保閥門的密封性能。
2、特殊材料制成的密封圈，具有耐高溫、耐磨損、使用壽命長的特點(diǎn)。
3、閥門結(jié)構(gòu)緊湊、啟閉靈活、安裝維修方便。

Construction Features

The Air operated ball valve series are designed for controllingthe powders containing dusts or solid bodies, especially for thosefields or systems as coal-powder injection in high-furnace, airflowlines, lance lines, etc.
1.Wear-auto-compensation equipment is applied with the valveseat to effectively ensure the sealing performance of the valve.
2.The seal ring made from exotic materials features such spe-c ialties as high-temperature resistance,abrasion-resistance, longservice-life, etc.
3.The valve bears those characteristics like compact structure,flexible on-off, and convenient method for installation and mainte-nance.
