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 屬于一種(zhong)補償(chang)(chang)元件。利用(yong)其工(gong)作主體波紋管(guan)(guan)(guan)(guan)的(de)有(you)效伸縮(suo)變形(xing),以吸收(shou)管(guan)(guan)(guan)(guan)線、導管(guan)(guan)(guan)(guan)、容器等由熱(re)(re)脹冷縮(suo)等原因而(er)(er)產生的(de)尺(chi)寸變化,或補償(chang)(chang)管(guan)(guan)(guan)(guan)線、導管(guan)(guan)(guan)(guan)、容器等的(de)軸向、橫向和角向位移。也可用(yong)于降噪減振(zhen)。在(zai)現(xian)代工(gong)業中(zhong)用(yong)途(tu)廣泛。供熱(re)(re)上,為了防止供熱(re)(re)管(guan)(guan)(guan)(guan)道升溫(wen)時,由于熱(re)(re)伸長或溫(wen)度應力(li)而(er)(er)引起管(guan)(guan)(guan)(guan)道變形(xing)或破壞,需要在(zai)管(guan)(guan)(guan)(guan)道上設置補償(chang)(chang)器,以補償(chang)(chang)管(guan)(guan)(guan)(guan)道的(de)熱(re)(re)伸長,從而(er)(er)減小(xiao)管(guan)(guan)(guan)(guan)壁的(de)應力(li)和作用(yong)在(zai)閥件或支架結構上的(de)作用(yong)力(li)。
