有些閥門上，填料函壓蓋法蘭都需要加彈簧墊圈DIN127B的。方斜墊圈，主要用它墊在槽鋼或工字鋼的斜面上，使螺母的支承面垂直于螺桿，避免扳擰螺絲時(shí)使螺桿受彎曲應(yīng)力。預(yù)載墊圈又稱預(yù)載指示墊圈，它可用來(lái)控制螺栓的擰緊程度。這種墊圈由4個(gè)零件組成：兩個(gè)普通平墊圈、一個(gè)屈服強(qiáng)度較低而厚度較厚的內(nèi)圈和一個(gè)屈服強(qiáng)度較高而厚度較薄的外圈，其工作原理為：在擰緊螺母時(shí)，內(nèi)圈受到壓力，直到屈服，并且厚度逐漸變薄，當(dāng)厚度降到外圈高度時(shí)，即表示螺栓的預(yù)緊力達(dá)到了設(shè)定值 </p><p style="text-indent:25px">墊圈紙墊它的用途有兩種。一是增加密封性，防止漏油；二是用來(lái)調(diào)整部件之間的間隙。使用紙墊的部件不可隨意增減，如柴油泵每側(cè)蓋間的紙墊是用來(lái)調(diào)整供油時(shí)間的，墊圈的厚度為0.1毫米，墊圈每增減0.1毫米，飛輪的供油角度就相應(yīng)改變1.7度。曲軸瓦與曲軸的軸向間隙也是通過(guò)調(diào)整飛輪端的側(cè)蓋與機(jī)體間的紙墊來(lái)實(shí)現(xiàn)。紙墊如果損壞應(yīng)及時(shí)更換，防止發(fā)生漏油現(xiàn)。平墊它的作用是通過(guò)平墊將螺母的壓力均勻地分布在受壓件上，同時(shí)保護(hù)螺栓絲扣和連接體的表面。一般薄的金屬殼體固定采用金屬平墊。防松墊圈安裝很簡(jiǎn)單,只需將兩片墊圈內(nèi)側(cè)斜齒面相對(duì),置于螺母和連接材料之間即可。</p><div

style="text-indent:25px">平墊圈DIN125主要用于減小壓強(qiáng)，當(dāng)有的部位擰緊軸向力很大時(shí)，易使墊圈壓成碟形，這時(shí)可改用材料和提高硬度來(lái)解決。彈簧墊圈DIN127B的鎖緊效果一般，重要部位盡量少用或不用，而采用自鎖結(jié)構(gòu)。對(duì)于用于高速擰緊（氣動(dòng)或電動(dòng)）的彈簧墊圈，較好采用表面磷化處理的墊圈，提高其減磨性能，否則易摩擦發(fā)熱而燒壞或張口，甚至損壞被連接件表面。對(duì)于薄板連接處，不應(yīng)采用彈簧墊圈結(jié)構(gòu)。據(jù)統(tǒng)計(jì)，彈簧墊圈在汽車上使用得越來(lái)越少了。齒形彈性墊圈中的連接齒形由于鎖緊力大而且均勻，在汽車行業(yè)中使用較多，而間隔齒型的則少一些。對(duì)于彈簧墊圈、彈性墊圈，根據(jù)國(guó)標(biāo)，一般可選擇GB699-1999《優(yōu)良碳素結(jié)構(gòu)鋼》中的60、70鋼和65Mn鋼。墊圈一般為扁平形的金屬環(huán)，用來(lái)保護(hù)被連接件的表面不受螺母擦傷。四川墊片采購(gòu)</p><p style="text-indent:25px">墊圈分為：平墊圈-C級(jí)、大墊圈-A和C級(jí)、特大墊圈-C級(jí)、小墊圈-A級(jí)等。進(jìn)口墊圈供應(yīng)</p><p style="text-indent:25px">平墊圈（DIN125/GB97），其形狀為截頭圓錐或球形。這些墊圈的偏轉(zhuǎn)范圍較小，但負(fù)載能力較高。變形時(shí)，它們會(huì)提供軸向力。像其他兩種類型的墊圈一樣，有時(shí)會(huì)回火到指定的硬度。具體而言，它們由不銹鋼或碳鋼，鈹銅或磷青銅制成。每個(gè)墊圈均由頂部組件和底部組建構(gòu)成，在擰緊螺栓時(shí)，它們會(huì)互鎖以產(chǎn)生張力，并可靠地將螺栓鎖定到位。由于墊圈的凸輪角大于螺栓螺距的升角，所以會(huì)產(chǎn)生張力。本質(zhì)上，即使受到極端振動(dòng)或動(dòng)態(tài)載荷，螺栓也會(huì)自鎖并保持這種狀態(tài)。進(jìn)口墊圈供應(yīng)</p><p
