Description

一种组合式密封件
技术领域
本发明涉及一种组合式密封件。
背景技术
钢铁公司，轧钢机工况条件比较恶劣，对密封件要求比较高，传统制作的密封件不能满足要求，同时由于缸体的磨损，随机配件也不适用，需要密封件有足够的弹性余量，实际生产中迫切需要有新型的密封件出现。传统的密封件性能比较单一，有的密封效果比较好，但是耐磨，耐压比较差，寿命低；有的耐磨，耐压等性能比较好，但是弹性密封效果差。组合式密封是近年来飞速发展的新型密封，是由两种或多种材料结合，充分发挥不同材料的优点，它逐渐被应用到工况条件比较恶劣的状态下，大大提高了密封性能。
发明内容
本发明要解决的技术问题是：基于上述问题，提供一种组合式密封件。
本发明解决其技术问题所采用的技术方案是：一种组合式密封件，包括主体密封和弹性体，主体密封呈Y字型，弹性体呈V字型，弹性体嵌设于主体密封的开口内壁，主体密封开口处内壁设有便于卡住弹性体的卡块，主体密封的材质为聚四氟乙烯，弹性体的材质为不锈钢。
进一步地，主体密封和弹性体卡接为一个整体。
本发明的有益效果是：密封效果好，通过加入不锈钢弹性体增加主体密封的弹性恢复，双卡口槽使不锈钢弹性体固定牢固，在安装和拆卸时不容易主副体密封分离，保护密封缸体不被划伤，在工作时受到冲击力，也不容易脱落。
附图说明
下面结合附图对本发明进一步说明。
图1是本发明的结构示意图。
其中：1.主体密封，2.弹性体。
具体实施方式
现在结合附图对本发明作进一步的说明。这些附图均为简化的示意图仅以示意方式说明本发明的基本结构，因此其仅显示与本发明有关的构成。
如图1所示的一种组合式密封件，包括主体密封1和弹性体2，主体密封1呈Y字型，弹性体2呈V字型，弹性体2嵌设于主体密封1的开口内壁，主体密封1开口处内壁设有便于卡住弹性体2的卡块，主体密封1的材质为聚四氟乙烯，弹性体2的材质为不锈钢。
主体密封1和弹性体2卡接为一个整体。
密封工作原理是采用赋能型密封，即随着液体压力的增加，密封件唇部压力就越大，密封效果就更好。通过加入弹性体2增加其弹性，即增加初始状态的密封效果，也增加了主体密封1的弹性恢复。双卡口槽使弹性体2固定牢固，在安装和拆卸时不容易主副体密封分离，保护密封缸体不被划伤，在工作时受到冲击力，也不容易脱落。
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
