波紋管膨脹節是用金屬波紋管制成的一種膨脹節。它能沿管道軸線方向伸縮,也允許少(shao)量(liang)彎曲。圖(tu)2為常見的軸向(xiang)式波(bo)(bo)紋(wen)管(guan)(guan)膨(peng)(peng)脹(zhang)節(jie)(jie)(jie),用(yong)(yong)(yong)在(zai)管(guan)(guan)道(dao)上進行軸向(xiang)長(chang)度(du)補償。為了防(fang)止超過(guo)允許的補償量(liang),在(zai)波(bo)(bo)紋(wen)管(guan)(guan)兩端(duan)設置有(you)保(bao)(bao)護拉桿或保(bao)(bao)護環,在(zai)與(yu)它連接的兩端(duan)管(guan)(guan)道(dao)上設置導向(xiang)支架。另外還(huan)有(you)轉(zhuan)角(jiao)式和橫向(xiang)式膨(peng)(peng)脹(zhang)節(jie)(jie)(jie),可用(yong)(yong)(yong)來補償管(guan)(guan)道(dao)的轉(zhuan)角(jiao)變形(xing)和橫向(xiang)變形(xing)。這類膨(peng)(peng)脹(zhang)節(jie)(jie)(jie)的優點是節(jie)(jie)(jie)省空間,節(jie)(jie)(jie)約材(cai)料,便于(yu)標準化(hua)和批量(liang)生產,缺點是壽命(ming)較短(duan)。波(bo)(bo)紋(wen)管(guan)(guan)膨(peng)(peng)脹(zhang)節(jie)(jie)(jie)一般(ban)用(yong)(yong)(yong)于(yu)溫度(du)和壓力不很高(gao)(gao)、長(chang)度(du)較短(duan)的管(guan)(guan)道(dao)上。隨著波(bo)(bo)紋(wen)管(guan)(guan)生產技術水(shui)平的提高(gao)(gao),這類膨(peng)(peng)脹(zhang)節(jie)(jie)(jie)的應用(yong)(yong)(yong)范圍正在(zai)擴大(da)。目(mu)前,波(bo)(bo)紋(wen)管(guan)(guan)膨(peng)(peng)脹(zhang)節(jie)(jie)(jie)可用(yong)(yong)(yong)在(zai)最(zui)高(gao)(gao)壓力6.0兆帕的管(guan)(guan)系(xi)中。
