膨脹(zhang)節習慣上(shang)也叫補(bu)償(chang)(chang)器(qi),或(huo)伸(shen)縮(suo)(suo)節。由構成(cheng)其工作主體(ti)的波(bo)紋(wen)管(guan)(guan)(guan)(guan)(一(yi)種(zhong)彈性(xing)元件(jian))和(he)端管(guan)(guan)(guan)(guan)、支架、法(fa)蘭、導管(guan)(guan)(guan)(guan)等附(fu)件(jian)組成(cheng)。 膨脹(zhang)節是(shi)為(wei)(wei)了(le)補(bu)償(chang)(chang)因溫度差與(yu)機械振(zhen)動引起的附(fu)加應(ying)力(li),而(er)設(she)置(zhi)在(zai)容(rong)器(qi)殼體(ti)或(huo)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)上(shang)的一(yi)種(zhong)撓性(xing)結(jie)構。利用(yong)(yong)其工作主體(ti)波(bo)紋(wen)管(guan)(guan)(guan)(guan)的有效伸(shen)縮(suo)(suo)變形(xing),以吸收管(guan)(guan)(guan)(guan)線、導管(guan)(guan)(guan)(guan)、容(rong)器(qi)等由熱脹(zhang)冷縮(suo)(suo)等原因而(er)產生的尺寸變化,或(huo)補(bu)償(chang)(chang)管(guan)(guan)(guan)(guan)線、導管(guan)(guan)(guan)(guan)、容(rong)器(qi)等的軸向、橫向和(he)角(jiao)向位移。也可用(yong)(yong)于降噪(zao)減(jian)振(zhen)。供熱上(shang),為(wei)(wei)了(le)防止供熱管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)升溫時,由于熱伸(shen)長或(huo)溫度應(ying)力(li)而(er)引起管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)變形(xing)或(huo)破(po)壞,需要(yao)在(zai)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)上(shang)設(she)置(zhi)補(bu)償(chang)(chang)器(qi),以補(bu)償(chang)(chang)管(guan)(guan)(guan)(guan)道(dao)(dao)(dao)的熱伸(shen)長,從而(er)減(jian)小管(guan)(guan)(guan)(guan)壁的應(ying)力(li)和(he)作用(yong)(yong)在(zai)閥(fa)件(jian)或(huo)支架結(jie)構上(shang)的作用(yong)(yong)力(li)。
