            超大口径阀门选型

            随着装置规模的不断扩大,超大口径调节阀及阀门应用得越来越多。由于角行程类阀结构简单、尺寸小、重量轻。故大口径阀门通常用角行程类阀(传统的闸阀也逐步会被蝶阀所代替)。公称通径大于300的直通阀、大于500的球阀和大于1200的蝶阀均属于超大口径的特殊阀。当阀门的口径以算术级数增加时,阀门在关闭时承受的静压力负荷会以几何级数增加。因此轴的强度,轴承的强度,轴承的负载,不平衡力和执行机构的推力等都是必须考虑的问题。

            选用超大口径阀门应注意的几个问题如下:

            因受力面积大,不平衡力大,不稳定因素多,因此,提高阀门整体刚度、强度和抗震性也是必须重点考虑的因素。

            系统的压力及压差不?#21830;?#22823;,以便能够提供有足够余量的大推力执行机构,并减轻重量。

            因噪声水?#25509;?#27969;量成比例,因此噪声水平是必须仔细考虑问题,应尽可能地选择直通流道或增设小?#30528;?#23556;型结构,减小流体通过节流口的速度和流量来降低噪声。

            对于大口径阀门,因尺寸大、重量大,运输、安装、维护都比?#32454;?#26434;,将阀门装到管线里以及拆卸和更换主要零部件都需使用吊车等设备,因此,提高可靠性、减轻重量也是一个需重点考虑的方面。
