紫(zi)銅墊片采(cai)用(yong)(yong)優質的紫銅(tong)(tong)板材具備(bei)良好的焊接(jie)性(xing), 可經冷、 熱塑性(xing)加工(gong)制成各(ge)種(zhong)半成品(pin)和成品(pin), 經數控車床精密車削(xue)確保密封面平直不翹曲,高(gao)精度研磨確保金屬面與法(fa)蘭密封面緊密貼 合。退火(huo)板材的室溫抗拉強度為(wei) 22~25 公(gong)斤力/毫 米 2,伸長率為(wei) 45~50%,布氏硬 度(HB)為(wei) 35~45。可以(yi)滿足(zu)客戶(hu)的淬火(huo)、酸洗等(deng)各(ge)種(zhong)要(yao)求。使用(yong)(yong)溫度小于(yu) 400℃ 材料選 擇: 銅(tong)(tong) Hpb59-1,H62,H65,H68(RoHS)環(huan)保銅(tong)(tong),紫銅(tong)(tong),硅青(qing)銅(tong)(tong),各(ge)種(zhong)鋁青(qing)銅(tong)(tong),錫青(qing)銅(tong)(tong),錳青(qing) 銅(tong)(tong),錳黃銅(tong)(tong),鉻鋯(gao)銅(tong)(tong)等(deng) 。 因為(wei)要(yao)檢驗紫銅墊片密封的作(zuo)用,所以(yi)(yi)要檢驗其(qi)兩面的平整度(du),不能(neng)有(you)凹陷,變形,裂(lie) 痕和劃痕。 這種(zhong)墊片采(cai)用的原材(cai)料是紫(zi)銅(tong)(tong) 因(yin)呈紫(zi)紅色而得名。它不一定是純銅(tong)(tong),有(you)時還加入少量脫氧(yang) 元素或其(qi)他元素,以(yi)(yi)改善材(cai)質和性能(neng),因(yin)此(ci)也歸(gui)入銅(tong)(tong)合金。
一種實心金(jin)屬墊片(pian),用(yong)金(jin)屬薄板沖(chong)壓或車削而成,取材(cai)廣(guang)泛,華英主要(yao)有鋁平墊、紫銅墊、不銹鋼墊等。由(you)于其密(mi)(mi)封(feng)依靠材(cai)料自身的壓縮回彈性,因此選用(yong)時一般選擇(ze)較軟(ruan)的材(cai)料,且需(xu)要(yao)有一定(ding)的壓緊力(li)才能密(mi)(mi)封(feng)。因為(wei)容易(yi)造(zao)成界面泄(xie)露,所以(yi)多數情(qing)況(kuang)下會被推薦用(yong)金屬齒形組合墊或金屬波齒復合墊片替(ti)代使用(yong)以達到(dao)(dao)更好的(de)(de)(de)(de)(de)密(mi)(mi)封(feng)(feng)性(xing)能,但其優點(dian)(dian)是加工(gong)簡(jian)單成(cheng)本低廉。多數情(qing)況下(xia)金屬(shu)平墊(dian)片也可(ke)(ke)以用(yong)和其它非金屬(shu)材料(liao)組合(he)使用(yong)以達到(dao)(dao)更好的(de)(de)(de)(de)(de)密(mi)(mi)封(feng)(feng)效(xiao)(xiao)果(guo)。根據不同的(de)(de)(de)(de)(de)介質和工(gong)況條件,可(ke)(ke)選擇(ze)柔性(xing)石(shi)墨(mo)、PTFE、無石(shi)棉板或(huo)其它一(yi)些軟金屬(shu),粘貼在墊(dian)片的(de)(de)(de)(de)(de)兩面,利用(yong)軟性(xing)覆蓋層的(de)(de)(de)(de)(de)密(mi)(mi)封(feng)(feng)性(xing)以及金屬(shu)的(de)(de)(de)(de)(de)強度、彈(dan)性(xing)好的(de)(de)(de)(de)(de)優點(dian)(dian),以達到(dao)(dao)更好的(de)(de)(de)(de)(de)密(mi)(mi)封(feng)(feng)效(xiao)(xiao)果(guo),大(da)多數情(qing)況下(xia)我們推(tui)薦石(shi)墨(mo)作為密(mi)(mi)封(feng)(feng)層,當介質對石(shi)墨(mo)產生(sheng)反應(ying)或(huo)要求潔凈環境時建議(yi)選擇(ze)新近推(tui)出(chu)的(de)(de)(de)(de)(de)性(xing)能的(de)(de)(de)(de)(de)膨體四氟作粘貼層,一(yi)般(ban)不需要很大(da)的(de)(de)(de)(de)(de)壓(ya)緊(jin)力(li),即(ji)可(ke)(ke)達到(dao)(dao)密(mi)(mi)封(feng)(feng)效(xiao)(xiao)果(guo)。
如果金屬平(ping)墊(dian)片(pian)規格較小的(de)情(qing)況下一般會被(bei)視作緊固件(jian)中配(pei)套墊(dian)圈,用(yong)來保護被(bei)連(lian)(lian)接(jie)件(jian)的(de)表面(mian)不受螺母擦傷,分散螺母對被(bei)連(lian)(lian)接(jie)件(jian)的(de)壓力,其形(xing)式(shi)也(ye)比較多樣如:平(ping)墊(dian)圈-C級(ji)、大墊(dian)圈-A和(he)C級(ji)、球面(mian)墊(dian)圈、錐面(mian)墊(dian)圈、波(bo)紋(wen)墊(dian)圈等(deng)。
金屬平墊片性能特點:
1.加工(gong)簡單,成本低廉。
2.材料廣泛(fan),使用方便。
3.可(ke)用(yong)于(yu)高壓(ya)部(bu)位(wei),與非(fei)金屬材(cai)料(liao)組合使用(yong)可(ke)以達到更好的使用(yong)效果。
應用范圍:
幾乎可用(yong)于任何(he)標準工業(ye)的(de)密(mi)(mi)封需(xu)求,從標準的(de)管道連接到閼門及大(da)型容器密(mi)(mi)封(換熱器、塔、罐(guan)、槽(cao)),***常用(yong)的(de)為標準件螺栓螺帽(mao)配套(tao)作為墊(dian)圈使用(yong)。
