快速排污阀结构原理

z44h快速排污阀是直接依靠介质压力产生的作用力来帮助作用于阀瓣上的机械荷密封的,作用在阀瓣上的机械载荷主要是来自压缩弹簧,这种几乎是固定的机械载荷。虽然对于压缩弹簧,加载的排污阀可以通过调整弹簧力来达到良好密封,但密封压差必须足够强,以保证足够的密封力,从而在阀正常运行时达到密封。密封压差还应小于启闭压差,以确保开启灵活。

快速排污阀采用主要标准

    ▲ 1、结构长度按JB/T6900-93的规定。 ▲ 2、标志按GB/T12220-1989的规定。 ▲ 3、压缩弹簧按GB/T1239.2的规定。 ▲ 4、压力--温度等级按GB9131的规定。 ▲ 5、Z44H排污阀法兰尺寸按JB79-59的规定。 ▲ 6、检验和试验按GB/T13927-1992的规定。 ▲ 7、 设计制造按GB/T12237-1989的规定。
