力士樂直動式高頻響方向閥,德國REXROTH高頻響方向閥資料
力士樂直動式高頻響方向閥用途廣泛,有很多種類,下面說的是供水和熱力常用的止回閥: 1、彈簧式:液體由下而上,依靠壓力頂起彈簧控制的閥瓣,壓力消失后,彈簧力將閥瓣壓下,封閉液體倒流。常用于通徑較小的止回閥。 2、重力式:和彈簧式相似,依靠閥瓣的自身重力封閉,防止倒流。 3、旋啟式:液體在閥體內直通,依靠壓力頂開一側的旋轉閥瓣,壓力失去后,閥瓣依靠自重回位,反向的液體壓力封閉閥瓣。 4.塑料隔膜式: 外殼和隔膜均為塑料.一般外殼為ABS,PE,PP,NYLON, PC.隔膜有硅樹脂,氟樹脂等. 其它的單向閥(止回閥),如排污的止回閥,人防的防爆閥和液體使用的止回閥的原理是大同小異。
