補償器習慣上也叫膨脹節,或伸縮節。由構成其工作主體的波紋管(一種彈性元件)和端管、支架、法蘭、導管等附件組成。膨脹節廠家 屬于(yu)一種補(bu)償元件(jian)。利用(yong)(yong)其工作(zuo)(zuo)主體波紋(wen)管(guan)(guan)(guan)的有效伸(shen)縮變(bian)形,以(yi)吸收管(guan)(guan)(guan)線、導管(guan)(guan)(guan)、容(rong)器等由熱脹(zhang)冷縮等原因而(er)產(chan)生的尺寸變(bian)化,或(huo)補(bu)償管(guan)(guan)(guan)線、導管(guan)(guan)(guan)、容(rong)器等的軸向(xiang)(xiang)、橫向(xiang)(xiang)和(he)(he)角(jiao)向(xiang)(xiang)位(wei)移(yi)。也可用(yong)(yong)于(yu)降噪(zao)減振(zhen)。在(zai)現代工業中用(yong)(yong)途廣泛。供(gong)熱上(shang),為了防止供(gong)熱管(guan)(guan)(guan)道(dao)(dao)(dao)升溫(wen)時,由于(yu)熱伸(shen)長(chang)或(huo)溫(wen)度應(ying)(ying)力而(er)引起(qi)管(guan)(guan)(guan)道(dao)(dao)(dao)變(bian)形或(huo)破壞,需(xu)要在(zai)管(guan)(guan)(guan)道(dao)(dao)(dao)上(shang)設置補(bu)償器,以(yi)補(bu)償管(guan)(guan)(guan)道(dao)(dao)(dao)的熱伸(shen)長(chang),從而(er)減小管(guan)(guan)(guan)壁的應(ying)(ying)力和(he)(he)作(zuo)(zuo)用(yong)(yong)在(zai)閥件(jian)或(huo)支架結構上(shang)的作(zuo)(zuo)用(yong)(yong)力。
