摘要
河南煤业化工集团中原大化公司煤化工500kt/y甲醇项目,该装置气化锁斗阀原先采用进口FL0WSERVE浮动球阀,金属密封。由于煤粉锁斗阀的高压差,高冲刷工作环境造成阀体,阀球及密封冲蚀严重,使得阀门极易损坏,阀门更换频繁严重影响生产。所以气化锁斗阀改造势在必行,历时半年的考察交流比较,最终选用国产上海福泰斯的盘阀。
Coal chemical industry group in Henan Zhongyuan Dahua Company coal chemical 500kt/y Methanol Project, the device gasification lock hopper valve originally imported FLOWSERVE floating ball valve, metal sealed. As a result of pulverized coal lock hopper valve high pressure difference, high flushing work environment caused by valve, ball valve and sealing of serious erosion, easy to damage the valve, valve replacement is frequent and serious effect on production. So the gasification lock hopper valve is changed imperative, lasted for half a year to inspect communication comparison, the final selection of domestic Shanghai Fu theis disc valve.
