膨脹(zhang)節習(xi)慣上(shang)(shang)也(ye)叫補(bu)償(chang)(chang)器(qi)(qi),或(huo)伸縮節。由構成其工作(zuo)主體的(de)(de)波紋(wen)管(guan)(guan)(guan)(一(yi)種(zhong)彈性(xing)元件(jian))和(he)端管(guan)(guan)(guan)、支(zhi)架、法蘭、導(dao)管(guan)(guan)(guan)等(deng)附件(jian)組成。 膨脹(zhang)節是為(wei)了補(bu)償(chang)(chang)因溫(wen)(wen)度差與(yu)機械振動引起的(de)(de)附加(jia)應力(li)(li),而設(she)置在容器(qi)(qi)殼體或(huo)管(guan)(guan)(guan)道上(shang)(shang)的(de)(de)一(yi)種(zhong)撓性(xing)結構。利用(yong)其工作(zuo)主體波紋(wen)管(guan)(guan)(guan)的(de)(de)有效伸縮變(bian)(bian)形,以(yi)吸收管(guan)(guan)(guan)線、導(dao)管(guan)(guan)(guan)、容器(qi)(qi)等(deng)由熱(re)(re)脹(zhang)冷縮等(deng)原(yuan)因而產生(sheng)的(de)(de)尺(chi)寸變(bian)(bian)化(hua),或(huo)補(bu)償(chang)(chang)管(guan)(guan)(guan)線、導(dao)管(guan)(guan)(guan)、容器(qi)(qi)等(deng)的(de)(de)軸向、橫向和(he)角向位移。也(ye)可用(yong)于降噪減(jian)振。供熱(re)(re)上(shang)(shang),為(wei)了防止供熱(re)(re)管(guan)(guan)(guan)道升(sheng)溫(wen)(wen)時,由于熱(re)(re)伸長(chang)或(huo)溫(wen)(wen)度應力(li)(li)而引起管(guan)(guan)(guan)道變(bian)(bian)形或(huo)破(po)壞,需(xu)要在管(guan)(guan)(guan)道上(shang)(shang)設(she)置補(bu)償(chang)(chang)器(qi)(qi),以(yi)補(bu)償(chang)(chang)管(guan)(guan)(guan)道的(de)(de)熱(re)(re)伸長(chang),從而減(jian)小管(guan)(guan)(guan)壁(bi)的(de)(de)應力(li)(li)和(he)作(zuo)用(yong)在閥(fa)件(jian)或(huo)支(zhi)架結構上(shang)(shang)的(de)(de)作(zuo)用(yong)力(li)(li)。
