膨脹(zhang)節習慣上(shang)(shang)也叫補(bu)(bu)償器,或(huo)(huo)(huo)伸(shen)縮節。由(you)構成其(qi)工(gong)作主(zhu)體的(de)波紋管(guan)(guan)(guan)(guan)(guan)(一(yi)種彈(dan)性元件)和端管(guan)(guan)(guan)(guan)(guan)、支架、法(fa)蘭、導(dao)(dao)管(guan)(guan)(guan)(guan)(guan)等(deng)附件組成。 膨脹(zhang)節是為(wei)了補(bu)(bu)償因溫度差與機械(xie)振(zhen)動引起的(de)附加應(ying)力(li),而(er)(er)設(she)置在容(rong)器殼體或(huo)(huo)(huo)管(guan)(guan)(guan)(guan)(guan)道上(shang)(shang)的(de)一(yi)種撓性結構。利用其(qi)工(gong)作主(zhu)體波紋管(guan)(guan)(guan)(guan)(guan)的(de)有效伸(shen)縮變(bian)形,以吸收(shou)管(guan)(guan)(guan)(guan)(guan)線、導(dao)(dao)管(guan)(guan)(guan)(guan)(guan)、容(rong)器等(deng)由(you)熱(re)脹(zhang)冷縮等(deng)原因而(er)(er)產生的(de)尺寸變(bian)化,或(huo)(huo)(huo)補(bu)(bu)償管(guan)(guan)(guan)(guan)(guan)線、導(dao)(dao)管(guan)(guan)(guan)(guan)(guan)、容(rong)器等(deng)的(de)軸向、橫向和角向位(wei)移。也可用于降(jiang)噪減振(zhen)。供(gong)熱(re)上(shang)(shang),為(wei)了防止(zhi)供(gong)熱(re)管(guan)(guan)(guan)(guan)(guan)道升溫時(shi),由(you)于熱(re)伸(shen)長或(huo)(huo)(huo)溫度應(ying)力(li)而(er)(er)引起管(guan)(guan)(guan)(guan)(guan)道變(bian)形或(huo)(huo)(huo)破(po)壞,需(xu)要在管(guan)(guan)(guan)(guan)(guan)道上(shang)(shang)設(she)置補(bu)(bu)償器,以補(bu)(bu)償管(guan)(guan)(guan)(guan)(guan)道的(de)熱(re)伸(shen)長,從而(er)(er)減小(xiao)管(guan)(guan)(guan)(guan)(guan)壁(bi)的(de)應(ying)力(li)和作用在閥件或(huo)(huo)(huo)支架結構上(shang)(shang)的(de)作用力(li)。
