膨脹(zhang)(zhang)節(jie)習慣(guan)上也叫補(bu)償(chang)器(qi),或(huo)(huo)(huo)伸(shen)縮節(jie)。由(you)構(gou)(gou)成其(qi)工作主體的波紋管(guan)(guan)(guan)(guan)(guan)(一種彈性(xing)元件(jian)(jian))和(he)端管(guan)(guan)(guan)(guan)(guan)、支(zhi)架(jia)、法蘭、導管(guan)(guan)(guan)(guan)(guan)等附件(jian)(jian)組成。 膨脹(zhang)(zhang)節(jie)是為了補(bu)償(chang)因(yin)溫度差與機械(xie)振(zhen)動引(yin)起(qi)的附加應(ying)力(li),而設置(zhi)在容(rong)器(qi)殼體或(huo)(huo)(huo)管(guan)(guan)(guan)(guan)(guan)道上的一種撓(nao)性(xing)結(jie)構(gou)(gou)。利用其(qi)工作主體波紋管(guan)(guan)(guan)(guan)(guan)的有效伸(shen)縮變(bian)形,以(yi)(yi)吸收管(guan)(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)(guan)、容(rong)器(qi)等由(you)熱脹(zhang)(zhang)冷縮等原因(yin)而產生的尺(chi)寸(cun)變(bian)化,或(huo)(huo)(huo)補(bu)償(chang)管(guan)(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)(guan)、容(rong)器(qi)等的軸向、橫向和(he)角向位移。也可用于降(jiang)噪減(jian)振(zhen)。供(gong)熱上,為了防止供(gong)熱管(guan)(guan)(guan)(guan)(guan)道升溫時,由(you)于熱伸(shen)長或(huo)(huo)(huo)溫度應(ying)力(li)而引(yin)起(qi)管(guan)(guan)(guan)(guan)(guan)道變(bian)形或(huo)(huo)(huo)破(po)壞,需要(yao)在管(guan)(guan)(guan)(guan)(guan)道上設置(zhi)補(bu)償(chang)器(qi),以(yi)(yi)補(bu)償(chang)管(guan)(guan)(guan)(guan)(guan)道的熱伸(shen)長,從而減(jian)小(xiao)管(guan)(guan)(guan)(guan)(guan)壁的應(ying)力(li)和(he)作用在閥件(jian)(jian)或(huo)(huo)(huo)支(zhi)架(jia)結(jie)構(gou)(gou)上的作用力(li)。
