膨(peng)脹(zhang)(zhang)節(jie)習慣上(shang)也叫補(bu)(bu)償器,或(huo)(huo)伸縮(suo)節(jie)。由構(gou)成其(qi)工(gong)作主體(ti)(ti)的(de)(de)波(bo)紋管(guan)(guan)(guan)(guan)(一(yi)種彈性(xing)元件(jian))和(he)(he)端(duan)管(guan)(guan)(guan)(guan)、支架、法蘭、導管(guan)(guan)(guan)(guan)等附件(jian)組成。 膨(peng)脹(zhang)(zhang)節(jie)是為(wei)了補(bu)(bu)償因溫(wen)(wen)度(du)差與機械振動引起(qi)的(de)(de)附加應力(li),而設置在(zai)容(rong)器殼(ke)體(ti)(ti)或(huo)(huo)管(guan)(guan)(guan)(guan)道(dao)上(shang)的(de)(de)一(yi)種撓性(xing)結構(gou)。利(li)用(yong)其(qi)工(gong)作主體(ti)(ti)波(bo)紋管(guan)(guan)(guan)(guan)的(de)(de)有效伸縮(suo)變(bian)形,以(yi)吸收管(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)、容(rong)器等由熱(re)脹(zhang)(zhang)冷(leng)縮(suo)等原因而產(chan)生的(de)(de)尺寸變(bian)化,或(huo)(huo)補(bu)(bu)償管(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)、容(rong)器等的(de)(de)軸向、橫向和(he)(he)角向位移。也可用(yong)于(yu)降噪減振。供(gong)熱(re)上(shang),為(wei)了防止(zhi)供(gong)熱(re)管(guan)(guan)(guan)(guan)道(dao)升溫(wen)(wen)時,由于(yu)熱(re)伸長或(huo)(huo)溫(wen)(wen)度(du)應力(li)而引起(qi)管(guan)(guan)(guan)(guan)道(dao)變(bian)形或(huo)(huo)破壞,需要在(zai)管(guan)(guan)(guan)(guan)道(dao)上(shang)設置補(bu)(bu)償器,以(yi)補(bu)(bu)償管(guan)(guan)(guan)(guan)道(dao)的(de)(de)熱(re)伸長,從而減小管(guan)(guan)(guan)(guan)壁的(de)(de)應力(li)和(he)(he)作用(yong)在(zai)閥件(jian)或(huo)(huo)支架結構(gou)上(shang)的(de)(de)作用(yong)力(li)。
