Description:

三通隔膜阀 G49W、G49J

部件列表:1、阀体 2、隔膜 3、阀瓣 4、阀杆 5、阀盖 6、手轮

二、三通隔膜阀用途:

三通隔膜阀用途:三通隔膜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流体管路。
适用温度:≤85℃、≤100℃、 ≤120℃、≤150℃(按照衬里和隔膜材料)
压力等级:PN1.0

三、三通隔膜阀材料:

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、三通隔膜阀测试:

衬里层:电火花检测
试验与检验按GB/T13297标准
公称压力:PN(Mpa)
阀体:PN×1.5
密封:PN×1.1

五、三通隔膜阀结构特点:

隔膜阀是一种特殊形式的截止阀
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,并具有良好的耐腐蚀性。
