膨脹節習慣(guan)上(shang)也(ye)叫補(bu)償(chang)器(qi),或(huo)(huo)伸縮節。由構成(cheng)其工(gong)作(zuo)主(zhu)(zhu)體(ti)的波紋(wen)管(guan)(guan)(guan)(guan)(一(yi)種彈(dan)性(xing)元件)和端管(guan)(guan)(guan)(guan)、支架、法蘭(lan)、導管(guan)(guan)(guan)(guan)等(deng)附件組成(cheng)。 膨脹節是為了(le)補(bu)償(chang)因溫度差(cha)與(yu)機械振動引起的附加(jia)應(ying)(ying)力(li)(li),而(er)設置在(zai)(zai)容(rong)器(qi)殼體(ti)或(huo)(huo)管(guan)(guan)(guan)(guan)道(dao)(dao)上(shang)的一(yi)種撓性(xing)結構。利用其工(gong)作(zuo)主(zhu)(zhu)體(ti)波紋(wen)管(guan)(guan)(guan)(guan)的有效伸縮變(bian)(bian)形(xing),以吸收管(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)、容(rong)器(qi)等(deng)由熱(re)脹冷縮等(deng)原因而(er)產生的尺寸變(bian)(bian)化(hua),或(huo)(huo)補(bu)償(chang)管(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)、容(rong)器(qi)等(deng)的軸向(xiang)、橫向(xiang)和角向(xiang)位移(yi)。也(ye)可用于降噪減振。供熱(re)上(shang),為了(le)防止(zhi)供熱(re)管(guan)(guan)(guan)(guan)道(dao)(dao)升溫時,由于熱(re)伸長或(huo)(huo)溫度應(ying)(ying)力(li)(li)而(er)引起管(guan)(guan)(guan)(guan)道(dao)(dao)變(bian)(bian)形(xing)或(huo)(huo)破壞,需要在(zai)(zai)管(guan)(guan)(guan)(guan)道(dao)(dao)上(shang)設置補(bu)償(chang)器(qi),以補(bu)償(chang)管(guan)(guan)(guan)(guan)道(dao)(dao)的熱(re)伸長,從而(er)減小管(guan)(guan)(guan)(guan)壁的應(ying)(ying)力(li)(li)和作(zuo)用在(zai)(zai)閥件或(huo)(huo)支架結構上(shang)的作(zuo)用力(li)(li)。
