纸厂内阀门使用V型调节阀球阀,阀体材质为316不锈钢,阀座与阀球进行硬化处理,现场工况温度不超过100℃,压力不超过1MPa,浆液管线上大面积出现了阀门出口阀体处磨损严重,有的甚至出现磨穿阀体的现象。请问除了进行阀腔内壁喷涂外还有什么解决方法?

首先要确认磨损严重的原因,是物料杂质引起的,还是其他原因导致的。 是否考虑从去除浆液中的颗粒杂质方面入手解决,否则不能从根门上解决问题,供参考。

阀腔内部全部喷涂WC,增加硬度

不知道陶瓷球阀对你们的工况是否适用,如果可以的话,阀体内衬陶瓷,阀体本身不锈钢,球体不锈钢喷涂WC,这样既保证了耐磨,球体也不容易碎,如果是介质造成阀体腐蚀就不适用了。

造纸工业中要用氯气作为漂白剂

管道颗粒太大,建议更换另一种规格的调节阀
