"闸阀和蝶阀在管道使用中都是起开关,调节流量的作用。当然在蝶阀和闸阀的选配过程中还是有方法的,上海阀门厂家来教大家如何选配:闸阀与蝶阀在供水管网中为了降低管道覆土深度,一般口径较大管道选配蝶阀,对覆土深度影响不大,力求选配闸阀,但是同样规格的闸阀价格又比蝶阀的价格高。至于口径的分界线应各地按具体情况考虑。从近十年使用情况而言,蝶阀出现的故障比闸阀高,因此在条件许可的情况下,扩大闸阀的使用范围是值得关注的。 关于闸阀近年来,国内不少阀门制造厂家,研制、仿制软密封闸阀,这种闸阀比传统的楔式或平行双闸板式闸阀有如下特点:a.软密封闸阀的阀体、阀盖采用精密铸造法铸造,一次成型,基本不机械加工,不使用密封铜环,节约有色金属。b.软密封闸阀底部无凹坑,不积存渣物,闸阀启闭的故障率低。c.软密封衬胶阀板尺寸统一,互换性强。因此软密封闸阀将是供水行业乐意采用的一种形式。目前国内制造的软密封闸阀口径达15
