产品简介
----------------------------------------------------------------------
DZ41W低温闸阀适用于甲烷、液态天然气、已烯、二氧化碳、液氨、液氧、液氮、液氢等低温介质,低温闸阀有二种阀盖设计形式。第一种是螺栓式阀盖,按这种设计的阀门,其阀体与阀盖用螺栓螺母连接,缠绕式垫片(316夹柔性石墨制造)。客户有特殊要求时也可采用金属环连接。第二种设计形式是焊接式阀盖,按这种设计形式的闸阀,其阀体与阀盖用螺纹连接,全焊密封。客户有特殊要求时也可采用透焊连接。低温闸阀特点
1、为防止中腔异常升压,在闸板的进口侧设置了泄压孔2、根据阀门的工作温度确定阀盖的顶部长度,确保阀桿填料的可靠密封
3、根据工作温度合理选用填料,垫片等零件的材料
4、低温闸阀严格控制材料的化学成份及低温冲击韧性等力学性能指标
5、低温闸阀采用多种配管法兰标准及密封面型式,适用于各种工程需要
