zpg-i型(直通式)自动排污过滤器 工作原理 管道系统在正常工作时，管道内杂物会收集到过滤器网内排污口上，不需拆卸过滤器任何部件来排除污物，只需打开排污阀即可排污。 ①在排污前先把过滤器前阀门，关小流量，进行排污，②排污时把转向阀转向冲洗方向，水从转向阀前部进入，往过滤网外部流过，然后又从过滤网外部进入转向阀后部，杂物全部集中到排污口上，然后再打开排污阀进行排污，起到了优秀自动反冲洗过滤器全部功能。 zpg-i型(直通式)自动排污过滤器型号 modellabcdzpg-i-40250180639015*zpg-i-502551857010015*zpg-i-652701908312020*zpg-i-803202259614025*zpg-i-10035025012818032*zpg-1-12543032016220040zpg-i-15052538018923050zpg-i-20070052022028065zpg-i-25087566025533080zpg-i-3001050790294380100zpg-i-3501200885330450125zpg-i-40014001040377480150zpg-i-45015501145420500150zpg-i-50017001250462580150zpg-i-60020001460537650200zpg-i-70022801720607700200zpg-i-80025001900685820200zpg-i-90028002180785880200zpg-i-100031202470860920250zpg-i-110034502780915960250zpg-i-1200370030009651040250zpg-i-15004470365012201400250
