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)量彎曲。圖2為常見的(de)軸向(xiang)式波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)膨(peng)脹(zhang)節(jie),用在管(guan)(guan)(guan)(guan)(guan)(guan)道上(shang)進行軸向(xiang)長(chang)度(du)補償。為了防止超(chao)過(guo)允許的(de)補償量,在波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)兩端(duan)設置有(you)保(bao)護(hu)拉桿或保(bao)護(hu)環,在與(yu)它連接的(de)兩端(duan)管(guan)(guan)(guan)(guan)(guan)(guan)道上(shang)設置導向(xiang)支架。另(ling)外還(huan)有(you)轉(zhuan)角(jiao)式和橫(heng)向(xiang)式膨(peng)脹(zhang)節(jie),可用來補償管(guan)(guan)(guan)(guan)(guan)(guan)道的(de)轉(zhuan)角(jiao)變(bian)形和橫(heng)向(xiang)變(bian)形。這類膨(peng)脹(zhang)節(jie)的(de)優點是節(jie)省空間,節(jie)約材(cai)料(liao),便于(yu)標準化和批量生產,缺點是壽(shou)命較短(duan)。波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)膨(peng)脹(zhang)節(jie)一般用于(yu)溫度(du)和壓力不很高(gao)、長(chang)度(du)較短(duan)的(de)管(guan)(guan)(guan)(guan)(guan)(guan)道上(shang)。隨著波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)生產技(ji)術水平(ping)的(de)提高(gao),這類膨(peng)脹(zhang)節(jie)的(de)應(ying)用范圍正在擴大。目前,波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)膨(peng)脹(zhang)節(jie)可用在最(zui)高(gao)壓力6.0兆帕(pa)的(de)管(guan)(guan)(guan)(guan)(guan)(guan)系中。
