膨脹節習慣(guan)上也叫補(bu)(bu)償器(qi)(qi)(qi),或(huo)伸縮(suo)節。由構成其工作主體的(de)(de)波紋(wen)管(guan)(guan)(guan)(guan)(一種(zhong)彈性元件)和(he)端管(guan)(guan)(guan)(guan)、支架、法蘭、導管(guan)(guan)(guan)(guan)等(deng)(deng)附(fu)(fu)件組成。 膨脹節是為了補(bu)(bu)償因(yin)溫度(du)差與(yu)機(ji)械(xie)振動(dong)引起(qi)(qi)的(de)(de)附(fu)(fu)加應力(li)(li),而(er)(er)(er)設置在容(rong)器(qi)(qi)(qi)殼體或(huo)管(guan)(guan)(guan)(guan)道上的(de)(de)一種(zhong)撓性結(jie)(jie)構。利用(yong)(yong)其工作主體波紋(wen)管(guan)(guan)(guan)(guan)的(de)(de)有效伸縮(suo)變(bian)(bian)形(xing),以吸(xi)收(shou)管(guan)(guan)(guan)(guan)線、導管(guan)(guan)(guan)(guan)、容(rong)器(qi)(qi)(qi)等(deng)(deng)由熱脹冷縮(suo)等(deng)(deng)原(yuan)因(yin)而(er)(er)(er)產生的(de)(de)尺(chi)寸變(bian)(bian)化,或(huo)補(bu)(bu)償管(guan)(guan)(guan)(guan)線、導管(guan)(guan)(guan)(guan)、容(rong)器(qi)(qi)(qi)等(deng)(deng)的(de)(de)軸向(xiang)(xiang)、橫(heng)向(xiang)(xiang)和(he)角向(xiang)(xiang)位移。也可用(yong)(yong)于降(jiang)噪減振。供熱上,為了防止供熱管(guan)(guan)(guan)(guan)道升(sheng)溫時(shi),由于熱伸長(chang)或(huo)溫度(du)應力(li)(li)而(er)(er)(er)引起(qi)(qi)管(guan)(guan)(guan)(guan)道變(bian)(bian)形(xing)或(huo)破壞,需要在管(guan)(guan)(guan)(guan)道上設置補(bu)(bu)償器(qi)(qi)(qi),以補(bu)(bu)償管(guan)(guan)(guan)(guan)道的(de)(de)熱伸長(chang),從而(er)(er)(er)減小管(guan)(guan)(guan)(guan)壁的(de)(de)應力(li)(li)和(he)作用(yong)(yong)在閥件或(huo)支架結(jie)(jie)構上的(de)(de)作用(yong)(yong)力(li)(li)。
