      一、产品介绍:
      
      FL641F气动放料阀是用气动执行器控制阀门,性能与用途:操作方便,开启自由,运动灵活可靠;阀瓣装配维修简单,密封结构合理,密封圈更换方便实用。结构:主要由阀体,阀瓣,密封圈,阀杆,支架,阀压盖,手轮,法兰,螺母,定位螺钉等零件。


      
      二、适用介质:
      
      (1)使用介质如水、丙酮、酒精、氨、碳酸钡、苯(WCB材质的温度使用-29℃-425℃)。 
      
      (2)使用介质如颗粒、油品、纸浆、二氧化碳气(不锈钢材质可使用温度-60℃-232℃)。 
      
      (3)严禁使用含氟离子液体(如HF等)也不能用强碱及磷酸(温度小于150℃,浓度>30%)。 
      
      (4)不锈钢的一般工作温度≤150℃,压力范围0.6-2.5MPA,超过此规定订货时要说明。 
      
      耐腐蚀性: 
      
      (1)聚四氟乙烯与金属粘结性优良,抗拉性一般,耐稀酸、浓酸等。 
      
      (2)使用介质如颗粒、油品、纸浆、二氧化碳气(不锈钢材质可使用温度-60℃-232℃)。 
      
      (3)严禁使用含氟离子液体(如HF等)也不能用强碱及磷酸(温度小于150℃,浓度>30%)。 
      
      (4)不锈钢的一般工作温度为-5℃-225℃,压力范围0.6-1.6MPA,超过此规定订货时要说明。
      
      三、安装注意事项:
      
      1、坚持阀瓣于封圈密封面无尘垢、泥沙。
      
      2、查看填料于活塞能否密封杰出,不得私自拆装,要技术人员的指导下。
      
      3、气缸拆下长时间不用时,一切加工外表应涂防锈油,进、排气口应加防尘阻塞。
