Description

一种便于双面涂层自润滑密封垫片 技术领域
本实用新型涉及密封配件制品技术领域，具体为一种便于双面涂层自润滑密封垫片。
背景技术
密封垫片，是一种用于机械、设备、管道只要是有流体的地方就是用的密封备件，使用内外部，起密封作用的材料。密封垫片是以金属或非金属板状材质，经切割，冲压或裁剪等工艺制成，用于管道之间的密封连接，起密封作用的材料。密封垫片是以金属或非金属板状材质，经切割，冲压或裁剪等工艺制成，用于管道之间的密封连接，机器设备的机件与机件之间的密封连接。按材质可分为金属密封垫片和非金属密封垫片。金属的有铜垫片，不锈钢垫片，铁垫片，铝垫片等。非金属的有石棉垫片，非石棉垫片，纸垫片，橡胶垫片等；目前主流的技术中，为了尽可能的减少主体的暴露，人们常常采用整体式结构的垫片，此类垫片在生产时其模具以及生产数量均受到限制；为此人们提出一种组合式密封垫片，如中国专利CN207634683U所公开的一种组合式密封垫片，包括两结构一致的可插接在一起的圆形本体；所述两圆形本体的相向面上设置有相应的插柱和承口，所述圆形本体的上下侧表面上设置有与所述通孔同心的环形密封线，所述环形密封线相对应的圆形本体内设有与所述环形密封线轨迹一致的空心压缩槽；所述圆形本体靠外的腰侧设有伸缩槽，所述伸缩槽的表面涂有耐蚀层。本实用新型将现有技术中的整体式密封垫片采用分段组合式设计，这样，原先在一个模具中仅能布置一个整体式模腔的模具结构，在采用分段式设计后，现在即可在不增大模具结构尺寸的前提下，就可布置多个分段式模腔，大大提高模具的利用率，降低模具的制作费用，大大提高密封垫片的生产效率；
但是在实际使用过程中，由于圆形本体组合时粘结剂的添加不够方便，操作起来费时费力，降低了工作效率。
实用新型内容
本实用新型的目的在于提供一种便于双面涂层自润滑密封垫片，对传统装置进行改进，解决了背景技术中的问题。
为实现上述目的，本实用新型提供如下技术方案：一种便于双面涂层自润滑密封垫片，包括对称设置的圆形本体一和圆形本体二，所述圆形本体一和圆形本体二相对面上的对应位置均固定连接有插柱，所述圆形本体一和圆形本体二的相对面上均开设有与插柱配合的承接口，所述插柱的表面固定连接有自覆盖装置。
所述自覆盖装置包括环形气囊，所述环形气囊的内缘与插柱的表面活动连接，所述圆形本体一和圆形本体二上靠近插柱的表面均开设有凹槽一，所述凹槽一的内壁与环形气囊的表面固定连接，所述环形气囊内填充有粘结剂，所述圆形本体一和圆形本体二上靠近凹槽一的表面均开设有凹槽二，所述凹槽二延伸至凹槽一内并与凹槽一连通，所述凹槽二内设有柱形气囊，所述柱形气囊上靠近环形气囊的一端贯穿环形气囊并延伸至环形气囊 内，所述凹槽二内远离柱形气囊一端的内壁固定连接有插针。
优选的，所述凹槽二的数量为两个，且两个凹槽二以插柱的竖直中心对称设置。
优选的，所述凹槽二上远离插柱一端的内壁上开设有凹槽三，且凹槽二上凹槽三的数量不少于四个。
优选的，所述圆形本体一和圆形本体二上靠近插柱的表面上均开设有回字形槽，所述回字形槽延伸至凹槽二内与凹槽二连通。
优选的，所述柱形气囊上延伸至环形气囊内的一端固定连接有单向阀，所述单向阀的导液口朝向插针。
优选的，所述插针为锥形插针，且其表面上开设有凸起。
与现有技术相比，本实用新型的有益效果如下：
一、本实用新型通过圆形本体一和圆形本体二上的插柱与承接口对应卡合，实现圆形本体一与圆形本体二的完整组装；在组装过程中，环形气囊会受到来自对应的圆形本体一和圆形本体二的挤压，环形气囊内压强增加会使其内的粘结剂被挤压至柱形气囊中，柱形气囊的体积随即膨胀，会使柱形气囊上远离环形气囊的一端膨胀移动至与插针的针尖接触并产生挤压，随即梓形气囊被刺破，柱形气囊中的粘结剂喷射出来，喷射出的粘结剂会快速将凹槽二填充满后再溢出至圆形本体一和圆形本体二的对应的相对面上，伴随着圆形本体一和圆形本体二的完整卡合，实现了粘结剂在圆形本体一和圆形本体二相对面上完成的涂抹，最终实现圆形本体一和圆形本体二的粘合固定；
二、本实用新型通过上述结构之间的配合使用，解决了在实际使用过程中，由于传统的圆形本体组合时粘结剂的添加不够方便，操作起来费时费力，降低了工作效率的问题。

工作原理：该便于双面涂层自润滑密封垫片在使用时，通过圆形本体一1和圆形本体二2上的插柱3与承接口4对应卡合，实现圆形本体一1与圆形本体二2的完整组装；在组装过程中，环形气囊6会受到来自对应的圆形本体一1和圆形本体二2的挤压，环形气囊6内压 强增加会使其内的粘结剂被挤压至柱形气囊9中，柱形气囊9的体积随即膨胀，会使柱形气囊9上远离环形气囊6的一端膨胀移动至与插针10的针尖接触并产生挤压，随即柱形气囊9被刺破，柱形气囊9中的粘结剂喷射出来，喷射出的粘结剂会快速将凹槽二8填充满后再溢出至圆形本体一1和圆形本体二2的对应的相对面上，伴随着圆形本体一1和圆形本体二2的完整卡合，实现了粘结剂在圆形本体一1和圆形本体二2相对面上完成自动的挤压式涂抹，最终实现圆形本体一1和圆形本体二2的粘合固定；通过上述结构之间的配合使用，解决了在实际使用过程中，由于传统的圆形本体组合时粘结剂的添加不够方便，操作起来费时费力，降低了工作效率的问题。
