                万博ti育app工作原理

                当罐na介质的ya力在万博ti育app的控zhicao作ya力范围之na时,万博ti育app不工作,保chi油罐的密闭性;当往罐nabu充介质,shi罐na上部气ti空jian的ya力升高,达到万博ti育app的cao作正ya时,ya力阀県uanタ鴗i从万博ti育app呼出口逸出,shi罐naya力不在继续增高;罐外的da气将顶开万博ti育app的负ya阀盘。万博ti育appshizhiji保证贮罐空jian在襤uan▂a力范围na与da气隔绝、又能在超过huo低于此ya力范围时与da气相通(呼吸)的一种阀门。其作yongshifang止贮罐yin超yahuozhen空导zhi破坏,同时ke减少贮液的蒸发损失。
