Description

一种装载机汽缸盖结构
技术领域
本发明属于装载机配件技术领域，涉及装载机汽缸盖结构。
背景技术
装载机汽缸普遍存在汽缸盖气门座孔水腔密封部位腐蚀问题，甚至因汽缸盖气门座孔内壁形成腐蚀坑，出现密封失效导致漏水的现象。冷水泄漏导致汽缸内燃烧异常，严重时会造成冷却水腔穿透，冷却水进入气缸内，导致汽缸盖、活塞连杆或曲轴报废，对发动机有危害。
 发明内容
本发明旨在克服现有技术的缺陷，提供了一种装载机汽缸盖结构，具有结构简单，密封型好的特点。
本发明的目的通过以下技术方案来具体实现：
一种装载机汽缸盖结构，装在汽缸体上部，包括汽缸盖1，汽缸盖1中央为喷油孔，汽缸盖1内侧有气门阀座4，气门阀座4和汽缸盖1之间设置有冷却水腔5，冷却空腔5位于气门阀座的一侧设置有密封圈3，气门阀座4内设置有气门阀2。
进一步地，汽缸盖材质为QT70-3的球墨铸铁。
与现有技术相比较，本发明具有如下的有益效果：
本发明塑料件结构简单，密封型好。且有良好的抗拉强度、耐腐蚀性，能够在高流速水流中的腐蚀试验使用。
附图说明
    图1是本发明装载机汽缸盖结构的示意图。
具体实施方式
以下结合附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
实施例  如图1所示，一种装载机汽缸盖结构，装在汽缸体上部，包括汽缸盖1，汽缸盖材质为QT70-3的球墨铸铁。汽缸盖1中央为喷油孔，汽缸盖1内侧有气门阀座4，气门阀座4和汽缸盖1之间设置有冷却水腔5，冷却空腔5位于气门阀座的一侧设置有密封圈3，气门阀座4内设置有气门阀2。
最后应说明的是：以上所述仅为说明本发明的实施方式，并不用于限制本发明，对于本领域的技术人员来说，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
