膨脹節(jie)習慣上也叫補(bu)(bu)(bu)償(chang)(chang)器,或(huo)伸縮節(jie)。由(you)構(gou)成其工作主(zhu)體的(de)(de)波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)(一(yi)種(zhong)彈性元(yuan)件)和(he)端(duan)管(guan)(guan)(guan)(guan)(guan)、支架、法蘭、導管(guan)(guan)(guan)(guan)(guan)等(deng)附件組成。 膨脹節(jie)是為了(le)補(bu)(bu)(bu)償(chang)(chang)因溫(wen)度差與機械振動引起的(de)(de)附加應(ying)力(li),而(er)設(she)置在(zai)容(rong)器殼體或(huo)管(guan)(guan)(guan)(guan)(guan)道(dao)上的(de)(de)一(yi)種(zhong)撓性結構(gou)。利用(yong)其工作主(zhu)體波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)的(de)(de)有效(xiao)伸縮變(bian)形,以吸收管(guan)(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)(guan)、容(rong)器等(deng)由(you)熱脹冷縮等(deng)原因而(er)產生的(de)(de)尺寸變(bian)化,或(huo)補(bu)(bu)(bu)償(chang)(chang)管(guan)(guan)(guan)(guan)(guan)線(xian)、導管(guan)(guan)(guan)(guan)(guan)、容(rong)器等(deng)的(de)(de)軸向、橫向和(he)角向位(wei)移。也可用(yong)于降噪減振。供熱上,為了(le)防止(zhi)供熱管(guan)(guan)(guan)(guan)(guan)道(dao)升溫(wen)時(shi),由(you)于熱伸長(chang)或(huo)溫(wen)度應(ying)力(li)而(er)引起管(guan)(guan)(guan)(guan)(guan)道(dao)變(bian)形或(huo)破壞,需要在(zai)管(guan)(guan)(guan)(guan)(guan)道(dao)上設(she)置補(bu)(bu)(bu)償(chang)(chang)器,以補(bu)(bu)(bu)償(chang)(chang)管(guan)(guan)(guan)(guan)(guan)道(dao)的(de)(de)熱伸長(chang),從而(er)減小(xiao)管(guan)(guan)(guan)(guan)(guan)壁的(de)(de)應(ying)力(li)和(he)作用(yong)在(zai)閥件或(huo)支架結構(gou)上的(de)(de)作用(yong)力(li)。
