尺寸图

部件列表:1.阀体 2.阀体衬里 3.隔膜 4.阀瓣 5.阀杆 6.阀盖 7.手轮

二、用途

    本阀专用于控制非腐蚀性或一般腐蚀性介质,阀体内腔表面无衬里或覆有可供选择的各种橡胶、适用于不同工作温度和液体管路。
适用温度:≤85℃、≤100℃、≤120℃、≤150℃
压力等级:PN(MPa) 0.6 1.0 1.6

三、材料

阀体:铸铁、球墨铸铁、碳钢、不锈钢
阀盖:铸铁、球墨铸铁、碳钢、不锈钢
衬里:无衬里、橡胶
隔膜:橡胶
阀瓣:铸铁
阀杆:碳钢、不锈钢
手轮:铸铁

四、测试

衬里层:电火花检测
试验与检验按BS6755标准
公称压力:PN(MPa)
阀体:PN×1.5 密封:PN×1.1

五、结构特点

隔膜阀是一种特殊形式的截断阀: 1、弹性密封的开闭件,确保没有内漏;
2、流线型的流道,使得压力损失小;
3、没有填料函,因此没有外漏;
4、阀体与盖被中间隔膜隔开,使得隔膜上方的阀盖,阀杆等零件不受介质侵蚀;
5、隔膜可更换,维护费用低;
6、衬里材料的多样性,可适用于各种介质,并具有强度高、耐腐蚀性能好的特点。
