    产品详情
    止回阀:止回阀又称单向阀或逆止阀,其作用是防止管路中的介质倒流。水泵吸水关的底阀也属于止回阀类。
    启闭件靠介质流动和力量自行开启或关闭,以防止介质倒流的阀门叫止回阀。止回阀属于自动阀类,主要用于介质单向流动的管道上,只允许介质向一个方向流动,以防止发生事故。
    止回阀按结构划分,可分为升降式止回阀、旋启式止回阀和蝶式止回阀三种。升降式止回阀可分为立式和卧式两","CompanyName":"上海卓越阀门有限公司","CompanyID":"82269","MarketPrice":"-1","PsOrder":"0","PgID":"0","MaxOrder":"0","CityID":"3","City":"上海市","Address":"上海市","PropertysValue":"","HitNumber":"104","FrontShow":"0","IsCharges":"0","Year":"7","StarNum":"2","UpdateAndClientSort":"8081820","StandUrl":"/st82269","UpdateTime":"2018/5/14 9:00:00","TodayIsUpdate":"0","AttType":"0","AttState":"0","AttAddType":"0","IsSeoCreate":"","IsOnlinePay":"0","MinPrice":"0.00","MaxPrice":"0.00","ClassID":"1759","productonlinetime":"1900/1/1 0:00:00","OnLineDate":"1900/1/1 0:00:00","DownLineDate":"1900/1/1 0:00:00","BrandPicDomin":"","BrandPicName":"","BrandProperty":"","PBrandID":"0","IsHadVideo":"0","VideoTime":"0","ShowPrice":"0.00"},{"ID":"3146312","Picture":"","PictureDomain":"","Name":"国标不锈钢升降式止回阀","Type":"H41H","Descrip":"H41H-16P/25P/40P/64P国标不锈钢升降式止回阀产品概述
