Q647F喷煤粉公用球阀-70088.com-80011js金沙娱城

产品结构特性

本系列气动球阀是作为掌握露尘、露固体粉末,稀奇适用于高炉煤粉喷吹、氛围管路及喷枪管路等体系。
1、阀座带有磨损主动赔偿装配,有用确保阀门的密封机能。
2、特别质料制成的密封圈,具有耐高温、耐磨益、使用寿命少的特性。
3、阀门构造松散、启闭天真、安装维修轻易。

Construction Features

The Air operated ball valve series are designed fcontrollingthe powders containing dusts solid bodies, especially fthosefields 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 thoseacteristics like compact structure,flexible on-off, convenient method finstallation mainte-nance.
