墊圈是指墊在被(bei)連(lian)接件(jian)與螺(luo)母之(zhi)間(jian)的(de)零件(jian)。一般為扁平形的(de)金屬環，用來(lai)保護(hu)被(bei)連(lian)接件(jian)的(de)表面不受(shou)螺(luo)母擦傷，分散螺(luo)母對被(bei)連(lian)接件(jian)的(de)壓力。

　　墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)分為(wei)：平墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)-C級、大墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)-A和C級、特大墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)-C級、小墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)-A級、平墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)-A級、平墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)-倒(dao)角型-A級、鋼結構用(yong)(yong)高強度墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、球面(mian)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、錐面(mian)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、工字鋼用(yong)(yong)方斜(xie)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、槽鋼用(yong)(yong)方斜(xie)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、標準(zhun)型彈(dan)(dan)簧墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、輕(qing)型彈(dan)(dan)簧墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、重型彈(dan)(dan)簧墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、內齒(chi)鎖緊(jin)(jin)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、內鋸(ju)(ju)齒(chi)鎖緊(jin)(jin)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、外(wai)齒(chi)鎖緊(jin)(jin)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、外(wai)鋸(ju)(ju)齒(chi)鎖緊(jin)(jin)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、單耳止(zhi)動墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、雙耳止(zhi)動墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、外(wai)舌(she)止(zhi)動墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、圓螺(luo)母(mu)用(yong)(yong)止(zhi)動墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)。

　　平墊(dian)圈一般(ban)用(yong)在連接(jie)件中一個是(shi)軟(ruan)(ruan)質地的(de)(de)，一個是(shi)硬質地較脆的(de)(de)，其主要作(zuo)用(yong)是(shi)增(zeng)大(da)接(jie)觸(chu)面積，分散壓(ya)(ya)力(li)，防止把質地軟(ruan)(ruan)的(de)(de)壓(ya)(ya)壞。而彈簧墊(dian)圈的(de)(de)彈簧的(de)(de)基本作(zuo)用(yong)是(shi)再螺(luo)母擰緊之(zhi)后給螺(luo)母一個力(li)，增(zeng)大(da)螺(luo)母和螺(luo)栓之(zhi)間的(de)(de)摩擦力(li)!材料(liao)為65Mn(彈簧鋼)、熱(re)處理(li)硬度(du)為HRC44～51HRC，經表面氧(yang)化處理(li)。

　　不銹鋼墊片的使用是非常的普遍,在使用不銹鋼墊片時,無論哪種類型,在惡劣使用環境中,應保證長時間的有效密封,否則不銹鋼墊片的使用作用就會(hui)無效,會(hui)嚴重(zhong)損零件(jian)或者其(qi)他工件(jian)的正常使用,因(yin)此我們在選擇不(bu)銹鋼墊片時,應主(zhu)語墊片要具備哪些特性(xing)。

　　不銹鋼墊片應具備的特點，無腐蝕性(xing)(xing)、抗黏接性(xing)(xing)、抗化學(xue)腐蝕、耐溫度、可壓縮性(xing)(xing)、氣密性(xing)(xing)、抗蠕變性(xing)(xing)、回彈性(xing)(xing)。

　　1、無(wu)腐蝕性:墊片應對(dui)連接(jie)的法蘭表面無(wu)腐蝕性。

　　2、抗黏接(jie)性:墊(dian)片(pian)在(zai)使用(yong)后應能方便(bian)的從法蘭上拆(chai)除,不粘接(jie)。

　　3、抗化(hua)學(xue)腐蝕:所選(xuan)用(yong)的墊片(pian)應不受化(hua)學(xue)介質的腐蝕,而且不能污染(ran)介質。

　　4、耐溫度:所選用的(de)墊片應保(bao)證在系(xi)統的(de)最低溫度和最高溫度下正常使用。

　　5、可壓縮(suo)性:墊片和法蘭的(de)接觸面在連接螺栓緊固后,應能(neng)很好吻合,以保證密封。

　　6、氣(qi)密(mi)性(xing):對(dui)于(yu)密(mi)封系統的(de)介質,墊片在推薦的(de)溫度和壓力工(gong)作一(yi)定時(shi)間內不發生(sheng)泄露。

　　7、抗蠕(ru)變(bian)性(xing):墊片在壓(ya)力負荷(he)和使用(yong)溫(wen)度(du)的影響(xiang)下,抗蠕(ru)變(bian)性(xing)應較好,否則回造成螺(luo)栓扭距損(sun)失,導致墊片的表面應力減(jian)小,從而硬氣(qi)系統(tong)泄露(lu)。

　　8、回彈性(xing)(xing):即使在系統穩定的(de)狀況下,相連(lian)接的(de)兩個法蘭由于溫度和壓力的(de)影(ying)響肯定會存在微小(xiao)位(wei)移,墊(dian)片的(de)彈性(xing)(xing)功能應能彌補此(ci)位(wei)移,以保證系統的(de)密封性(xing)(xing)。
