換(huan)熱器(qi)中(zhong),內嵌管板(ban)是一(yi)種重要的(de)組成部件,現有(you)的(de)管板(ban)兼(jian)做(zuo)法蘭的(de)鈦換(huan)熱器(qi)存在以下不足:

　　一(yi)、由于(yu)鈦材(cai)(cai)與其他材(cai)(cai)質無法(fa)焊接的特性,法(fa)蘭和管(guan)板都需要鈦材(cai)(cai),因此,較大(da)的增加了鈦材(cai)(cai)使用量。

　　二、由于鈦材厚(hou)度對(dui)設計壓力(li)影響較大,因此,當設計壓力(li)增(zeng)加時,法蘭(lan)和管板厚(hou)度將同(tong)步增(zeng)加。

　　為此研究(jiu)(jiu)人員研究(jiu)(jiu)出(chu)了(le)一(yi)種適(shi)應不同設(she)計壓力,同時可以采用襯環(huan)活(huo)套(tao)法蘭結構的內嵌管(guan)鈦換熱器(qi)。

　　該三層復(fu)合(he)管(guan)(guan)(guan)(guan)(guan)板(ban)鈦式換(huan)(huan)熱(re)器的結構包括管(guan)(guan)(guan)(guan)(guan)板(ban)、定距(ju)管(guan)(guan)(guan)(guan)(guan)、拉桿、螺母(mu)、防松(song)(song)(song)支(zhi)(zhi)(zhi)(zhi)耳(er)(er)、支(zhi)(zhi)(zhi)(zhi)撐(cheng)(cheng)板(ban)、U形換(huan)(huan)熱(re)管(guan)(guan)(guan)(guan)(guan),U形換(huan)(huan)熱(re)管(guan)(guan)(guan)(guan)(guan)為多根,多根U形換(huan)(huan)熱(re)管(guan)(guan)(guan)(guan)(guan)重疊在(zai)(zai)一起后穿過管(guan)(guan)(guan)(guan)(guan)板(ban),U形換(huan)(huan)熱(re)管(guan)(guan)(guan)(guan)(guan)通過防松(song)(song)(song)支(zhi)(zhi)(zhi)(zhi)耳(er)(er)固定在(zai)(zai)支(zhi)(zhi)(zhi)(zhi)撐(cheng)(cheng)板(ban)上(shang),防松(song)(song)(song)支(zhi)(zhi)(zhi)(zhi)耳(er)(er)為多片(pian),多片(pian)防松(song)(song)(song)支(zhi)(zhi)(zhi)(zhi)耳(er)(er)等間距(ju)設置(zhi),防松(song)(song)(song)支(zhi)(zhi)(zhi)(zhi)耳(er)(er)之(zhi)(zhi)間設置(zhi)定距(ju)管(guan)(guan)(guan)(guan)(guan),拉桿一端(duan)連(lian)接(jie)在(zai)(zai)管(guan)(guan)(guan)(guan)(guan)板(ban)上(shang),另一端(duan)穿過定距(ju)管(guan)(guan)(guan)(guan)(guan)、防松(song)(song)(song)支(zhi)(zhi)(zhi)(zhi)耳(er)(er)后通過螺母(mu)壓緊,管(guan)(guan)(guan)(guan)(guan)板(ban)采用(yong)三層復(fu)合(he)材(cai)料制成。防松(song)(song)(song)支(zhi)(zhi)(zhi)(zhi)耳(er)(er)為五片(pian)。防松(song)(song)(song)支(zhi)(zhi)(zhi)(zhi)耳(er)(er)與(yu)(yu)(yu)支(zhi)(zhi)(zhi)(zhi)撐(cheng)(cheng)板(ban)之(zhi)(zhi)間為固定連(lian)接(jie)。U形換(huan)(huan)熱(re)管(guan)(guan)(guan)(guan)(guan)與(yu)(yu)(yu)管(guan)(guan)(guan)(guan)(guan)板(ban)之(zhi)(zhi)間設置(zhi)緩(huan)沖套。U形換(huan)(huan)熱(re)管(guan)(guan)(guan)(guan)(guan)與(yu)(yu)(yu)管(guan)(guan)(guan)(guan)(guan)板(ban)之(zhi)(zhi)間的緩(huan)沖套選(xuan)用(yong)鋼材(cai)。U形換(huan)(huan)熱(re)管(guan)(guan)(guan)(guan)(guan)穿過管(guan)(guan)(guan)(guan)(guan)板(ban)后與(yu)(yu)(yu)管(guan)(guan)(guan)(guan)(guan)板(ban)進行焊接(jie)。
