膨(peng)脹(zhang)節習慣(guan)上(shang)也(ye)叫補(bu)(bu)償(chang)器,或(huo)(huo)伸縮節。由(you)(you)構成其工(gong)作主(zhu)體的波(bo)紋管(guan)(guan)(guan)(一種彈(dan)性(xing)元件)和(he)端管(guan)(guan)(guan)、支(zhi)架、法蘭、導(dao)管(guan)(guan)(guan)等(deng)附件組成。 膨(peng)脹(zhang)節是為了(le)補(bu)(bu)償(chang)因溫(wen)度差與機械振動引起的附加應(ying)力(li)(li),而(er)(er)設(she)(she)置(zhi)在容器殼體或(huo)(huo)管(guan)(guan)(guan)道上(shang)的一種撓性(xing)結構。利用(yong)其工(gong)作主(zhu)體波(bo)紋管(guan)(guan)(guan)的有(you)效伸縮變(bian)形,以吸收管(guan)(guan)(guan)線(xian)(xian)、導(dao)管(guan)(guan)(guan)、容器等(deng)由(you)(you)熱脹(zhang)冷縮等(deng)原因而(er)(er)產生的尺寸變(bian)化,或(huo)(huo)補(bu)(bu)償(chang)管(guan)(guan)(guan)線(xian)(xian)、導(dao)管(guan)(guan)(guan)、容器等(deng)的軸向、橫向和(he)角向位移(yi)。也(ye)可用(yong)于(yu)降噪(zao)減(jian)振。供熱上(shang),為了(le)防止(zhi)供熱管(guan)(guan)(guan)道升溫(wen)時(shi),由(you)(you)于(yu)熱伸長(chang)或(huo)(huo)溫(wen)度應(ying)力(li)(li)而(er)(er)引起管(guan)(guan)(guan)道變(bian)形或(huo)(huo)破壞,需要在管(guan)(guan)(guan)道上(shang)設(she)(she)置(zhi)補(bu)(bu)償(chang)器,以補(bu)(bu)償(chang)管(guan)(guan)(guan)道的熱伸長(chang),從而(er)(er)減(jian)小管(guan)(guan)(guan)壁的應(ying)力(li)(li)和(he)作用(yong)在閥件或(huo)(huo)支(zhi)架結構上(shang)的作用(yong)力(li)(li)。
