金屬纏(chan)繞墊片

金(jin)屬(shu)(shu)纏(chan)繞墊(dian)(dian)片(pian)(pian)是目(mu)前(qian)應(ying)用廣泛的一種密(mi)(mi)封墊(dian)(dian)片(pian)(pian)，為(wei)半金(jin)屬(shu)(shu)密(mi)(mi)合(he)墊(dian)(dian)中回彈性的墊(dian)(dian)片(pian)(pian)，由V形(xing)(xing)或W形(xing)(xing)薄鋼(gang)帶與各種填充(chong)料(liao)交替纏(chan)繞而(er)成，能耐高(gao)溫(wen)、高(gao)壓(ya)和(he)(he)適(shi)應(ying)超低溫(wen)或真空下的條件使用，通過(guo)改變(bian)墊(dian)(dian)片(pian)(pian)的材料(liao)組合(he)，可(ke)解決各種介質(zhi)對墊(dian)(dian)片(pian)(pian)的化學腐(fu)蝕問題，其(qi)結構密(mi)(mi)度(du)可(ke)依據(ju)不同的鎖緊力要求來制(zhi)作，為(wei)加強(qiang)主體(ti)和(he)(he)準確定(ding)位(wei)，纏(chan)繞墊(dian)(dian)片(pian)(pian)設(she)有(you)金(jin)屬(shu)(shu)內加強(qiang)環和(he)(he)外定(ding)位(wei)環，利(li)用內外鋼(gang)環來控制(zhi)其(qi)大壓(ya)緊度(du)，對墊(dian)(dian)片(pian)(pian)接觸的法(fa)蘭密(mi)(mi)封面的表面精度(du)要求不高(gao)。

主要用途(tu)

回彈性優良的(de)(de)金屬(shu)纏繞墊片能夠(gou)對(dui)管道系統的(de)(de)壓力熱循環和振動進行

自(zi)動(dong)調(diao)整(zheng)，特別適(shi)用于負荷不均(jun)勻、接(jie)合力易(yi)松弛，溫度(du)與壓(ya)力周期性變(bian)化、有(you)沖擊或震動(dong)的場合。是閥門、泵、換熱(re)器、塔(ta)、人孔、手(shou)孔等法蘭連接(jie)處(chu)的靜(jing)密封原件，廣泛地用于石化、機械(xie)、電力、冶(ye)金、造船、醫藥、原子能和宇航等部門。

在法(fa)蘭墊(dian)外觀設計上為了安裝方便,根據墊(dian)片(pian)口徑大(da)小,在墊(dian)片(pian)外圍焊上2~8個定位帶,讓定位帶扣在法(fa)蘭孔上,以防安裝時(shi)墊(dian)片(pian)移位或脫落,節約了輔助(zhu)材料(liao)及工時(shi).一(yi)般分為以下幾(ji)種類(lei)型:

金(jin)屬(shu)纏(chan)(chan)(chan)繞(rao)墊(dian)(dian)(dian)(dian)(dian)(dian)片采用(yong)(yong)優質SUS304、SUS316("V"形(xing)或(huo)"W"形(xing)) 金(jin)屬(shu)帶(dai)及其它合金(jin)材料與石墨、石棉(mian)、聚四(si)氟乙(yi)烯墊(dian)(dian)(dian)(dian)(dian)(dian)片、無石棉(mian)等軟(ruan)性材料相互交替重(zhong)疊(die)螺旋纏(chan)(chan)(chan)繞(rao)而成，在開始及末端用(yong)(yong)點焊方式將(jiang)金(jin)屬(shu)帶(dai)固定(ding)。金(jin)屬(shu)纏(chan)(chan)(chan)繞(rao)墊(dian)(dian)(dian)(dian)(dian)(dian)片為半金(jin)屬(shu)密(mi)合墊(dian)(dian)(dian)(dian)(dian)(dian)中(zhong)回彈(dan)性墊(dian)(dian)(dian)(dian)(dian)(dian)片，金(jin)屬(shu)纏(chan)(chan)(chan)繞(rao)墊(dian)(dian)(dian)(dian)(dian)(dian)片結構密(mi)度可(ke)依據不同的鎖(suo)緊力要(yao)求來制作，并利用(yong)(yong)內外鋼環(huan)來控制其大壓(ya)緊度，纏(chan)(chan)(chan)繞(rao)墊(dian)(dian)(dian)(dian)(dian)(dian)片接觸的法蘭(lan)密(mi)封面(mian)的表面(mian)精度要(yao)求不高。金(jin)屬(shu)纏(chan)(chan)(chan)繞(rao)墊(dian)(dian)(dian)(dian)(dian)(dian)片特(te)別(bie)適用(yong)(yong)于負荷不均勻、接合力易(yi)松弛(chi)，溫度與壓(ya)力周期性變化、有(you)沖擊或(huo)震動的場合。纏(chan)(chan)(chan)繞(rao)墊(dian)(dian)(dian)(dian)(dian)(dian)片是閥門、泵(beng)、換熱(re)器、塔、人(ren)孔、手(shou)孔等法蘭(lan)連接處理想的靜密(mi)封原件。

纏繞墊片應用范圍:

石(shi)油、化工、冶金、電力、船舶(bo)、機械等(deng)行(xing)業的管道、閥門、壓力容器、冷凝器、換熱器、塔、人孔、手孔等(deng)法蘭連接(jie)處密封。
