膨脹(zhang)節習慣上(shang)(shang)也叫(jiao)補(bu)(bu)償(chang)(chang)器(qi),或(huo)(huo)伸(shen)(shen)縮節。由(you)構(gou)成其工(gong)作(zuo)主體的(de)(de)波紋管(guan)(guan)(guan)(guan)(一(yi)種(zhong)彈性元(yuan)件(jian))和端管(guan)(guan)(guan)(guan)、支架、法蘭、導(dao)管(guan)(guan)(guan)(guan)等附件(jian)組成。 膨脹(zhang)節是為(wei)了補(bu)(bu)償(chang)(chang)因溫度(du)(du)差與機械(xie)振動引(yin)起的(de)(de)附加應(ying)力,而(er)設置在(zai)容(rong)(rong)器(qi)殼體或(huo)(huo)管(guan)(guan)(guan)(guan)道(dao)上(shang)(shang)的(de)(de)一(yi)種(zhong)撓性結構(gou)。利用其工(gong)作(zuo)主體波紋管(guan)(guan)(guan)(guan)的(de)(de)有效伸(shen)(shen)縮變(bian)形,以吸收管(guan)(guan)(guan)(guan)線、導(dao)管(guan)(guan)(guan)(guan)、容(rong)(rong)器(qi)等由(you)熱脹(zhang)冷縮等原因而(er)產生的(de)(de)尺寸變(bian)化(hua),或(huo)(huo)補(bu)(bu)償(chang)(chang)管(guan)(guan)(guan)(guan)線、導(dao)管(guan)(guan)(guan)(guan)、容(rong)(rong)器(qi)等的(de)(de)軸向(xiang)(xiang)、橫(heng)向(xiang)(xiang)和角向(xiang)(xiang)位移(yi)。也可用于降(jiang)噪(zao)減(jian)振。供熱上(shang)(shang),為(wei)了防止供熱管(guan)(guan)(guan)(guan)道(dao)升溫時(shi),由(you)于熱伸(shen)(shen)長或(huo)(huo)溫度(du)(du)應(ying)力而(er)引(yin)起管(guan)(guan)(guan)(guan)道(dao)變(bian)形或(huo)(huo)破(po)壞(huai),需要(yao)在(zai)管(guan)(guan)(guan)(guan)道(dao)上(shang)(shang)設置補(bu)(bu)償(chang)(chang)器(qi),以補(bu)(bu)償(chang)(chang)管(guan)(guan)(guan)(guan)道(dao)的(de)(de)熱伸(shen)(shen)長,從(cong)而(er)減(jian)小(xiao)管(guan)(guan)(guan)(guan)壁的(de)(de)應(ying)力和作(zuo)用在(zai)閥(fa)件(jian)或(huo)(huo)支架結構(gou)上(shang)(shang)的(de)(de)作(zuo)用力。
