膨脹(zhang)節(jie)習慣上(shang)(shang)(shang)也(ye)叫補償(chang)(chang)(chang)(chang)器(qi)(qi),或(huo)(huo)伸縮節(jie)。由(you)構成(cheng)其工作(zuo)(zuo)主(zhu)體的(de)(de)(de)(de)波(bo)紋管(guan)(guan)(guan)(guan)(一(yi)種彈性元(yuan)件(jian))和端管(guan)(guan)(guan)(guan)、支架、法蘭、導管(guan)(guan)(guan)(guan)等附件(jian)組成(cheng)。 膨脹(zhang)節(jie)是(shi)為(wei)了(le)補償(chang)(chang)(chang)(chang)因溫度(du)差與機(ji)械振動引(yin)起(qi)的(de)(de)(de)(de)附加應力(li),而(er)設(she)置(zhi)在容器(qi)(qi)殼(ke)體或(huo)(huo)管(guan)(guan)(guan)(guan)道上(shang)(shang)(shang)的(de)(de)(de)(de)一(yi)種撓性結構。利用(yong)(yong)其工作(zuo)(zuo)主(zhu)體波(bo)紋管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)有效伸縮變形(xing)(xing),以(yi)吸(xi)收(shou)管(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)、容器(qi)(qi)等由(you)熱(re)(re)脹(zhang)冷縮等原因而(er)產生的(de)(de)(de)(de)尺(chi)寸變化,或(huo)(huo)補償(chang)(chang)(chang)(chang)管(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)、容器(qi)(qi)等的(de)(de)(de)(de)軸向、橫向和角向位移。也(ye)可用(yong)(yong)于(yu)降噪(zao)減(jian)振。供(gong)熱(re)(re)上(shang)(shang)(shang),為(wei)了(le)防止供(gong)熱(re)(re)管(guan)(guan)(guan)(guan)道升溫時,由(you)于(yu)熱(re)(re)伸長或(huo)(huo)溫度(du)應力(li)而(er)引(yin)起(qi)管(guan)(guan)(guan)(guan)道變形(xing)(xing)或(huo)(huo)破壞,需要(yao)在管(guan)(guan)(guan)(guan)道上(shang)(shang)(shang)設(she)置(zhi)補償(chang)(chang)(chang)(chang)器(qi)(qi),以(yi)補償(chang)(chang)(chang)(chang)管(guan)(guan)(guan)(guan)道的(de)(de)(de)(de)熱(re)(re)伸長,從而(er)減(jian)小管(guan)(guan)(guan)(guan)壁(bi)的(de)(de)(de)(de)應力(li)和作(zuo)(zuo)用(yong)(yong)在閥件(jian)或(huo)(huo)支架結構上(shang)(shang)(shang)的(de)(de)(de)(de)作(zuo)(zuo)用(yong)(yong)力(li)。
