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(shu)于(yu)一種(zhong)補償元件。利用其工作(zuo)主體(ti)波紋(wen)管(guan)(guan)(guan)(guan)的有效伸(shen)縮變形,以吸收(shou)管(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)、容(rong)器(qi)(qi)等由熱(re)脹(zhang)冷縮等原因(yin)而(er)產生的尺寸變化,或(huo)補償管(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)、容(rong)器(qi)(qi)等的軸向、橫(heng)向和角向位移。也可用于(yu)降噪(zao)減振(zhen)。在現(xian)代工業中用途廣泛(fan)。供熱(re)上(shang),為了防止供熱(re)管(guan)(guan)(guan)(guan)道(dao)(dao)升(sheng)溫(wen)時,由于(yu)熱(re)伸(shen)長或(huo)溫(wen)度應力而(er)引(yin)起管(guan)(guan)(guan)(guan)道(dao)(dao)變形或(huo)破壞,需要在管(guan)(guan)(guan)(guan)道(dao)(dao)上(shang)設(she)置補償器(qi)(qi),以補償管(guan)(guan)(guan)(guan)道(dao)(dao)的熱(re)伸(shen)長,從(cong)而(er)減小管(guan)(guan)(guan)(guan)壁的應力和作(zuo)用在閥件或(huo)支(zhi)架結(jie)構上(shang)的作(zuo)用力。
