膨脹節(jie)習(xi)慣上(shang)也叫補(bu)償(chang)(chang)器(qi),或(huo)(huo)(huo)伸縮節(jie)。由(you)構成(cheng)其工作(zuo)主(zhu)(zhu)體的(de)(de)波紋管(guan)(guan)(guan)(guan)(一種(zhong)彈性元件(jian)(jian))和端管(guan)(guan)(guan)(guan)、支架、法(fa)蘭、導管(guan)(guan)(guan)(guan)等(deng)附(fu)件(jian)(jian)組成(cheng)。 膨脹節(jie)是為了補(bu)償(chang)(chang)因溫度差(cha)與機械振(zhen)動引起的(de)(de)附(fu)加應力(li),而設(she)置(zhi)在(zai)容(rong)器(qi)殼體或(huo)(huo)(huo)管(guan)(guan)(guan)(guan)道(dao)(dao)上(shang)的(de)(de)一種(zhong)撓(nao)性結(jie)(jie)構。利(li)用(yong)(yong)其工作(zuo)主(zhu)(zhu)體波紋管(guan)(guan)(guan)(guan)的(de)(de)有(you)效伸縮變(bian)形(xing),以(yi)吸收(shou)管(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)、容(rong)器(qi)等(deng)由(you)熱(re)(re)脹冷(leng)縮等(deng)原因而產生的(de)(de)尺寸變(bian)化,或(huo)(huo)(huo)補(bu)償(chang)(chang)管(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)、容(rong)器(qi)等(deng)的(de)(de)軸向、橫向和角(jiao)向位移(yi)。也可(ke)用(yong)(yong)于(yu)降噪減振(zhen)。供熱(re)(re)上(shang),為了防止供熱(re)(re)管(guan)(guan)(guan)(guan)道(dao)(dao)升溫時,由(you)于(yu)熱(re)(re)伸長或(huo)(huo)(huo)溫度應力(li)而引起管(guan)(guan)(guan)(guan)道(dao)(dao)變(bian)形(xing)或(huo)(huo)(huo)破壞(huai),需要在(zai)管(guan)(guan)(guan)(guan)道(dao)(dao)上(shang)設(she)置(zhi)補(bu)償(chang)(chang)器(qi),以(yi)補(bu)償(chang)(chang)管(guan)(guan)(guan)(guan)道(dao)(dao)的(de)(de)熱(re)(re)伸長,從而減小(xiao)管(guan)(guan)(guan)(guan)壁的(de)(de)應力(li)和作(zuo)用(yong)(yong)在(zai)閥件(jian)(jian)或(huo)(huo)(huo)支架結(jie)(jie)構上(shang)的(de)(de)作(zuo)用(yong)(yong)力(li)。
