Abstract

本发明涉及一种用于电力机车牵引变压器油循环冷却装置中的蝶阀，特别是用于新八轴动车高铁车牵引变压器中。它包括阀体、阀片、转轴、轴头盖、密封件和密封槽，阀体一侧法兰面上为中间厚、边上薄的结构,其另一侧为平面结构；密封槽外上下、左右四个方向各延伸出一段加强筋；转轴轴头上端加工成六角形状,在该段六角形状部位靠顶端加工成半六角形状；轴头盖上有一个腰形沉孔,在腰形沉孔底部各有一个与横向和纵向的半圆开关键对应的沉孔，可套在半六角形状的转轴上,轴头盖紧固在阀体上。通过结构改进,使轴头盖锁住转轴及阀片，提高了蝶阀的操作安全可靠性，同时阀体的重量减轻、强度增大，节省了成本，并可减少震动和渗漏。

Description

一种蝶阀
技术领域
本发明涉及一种用于电力机车牵引变压器油循环冷却装置中的蝶阀，特别适用于新八轴动车高铁车牵引变压器中。
背景技术
金属蝶阀主要包括阀体、阀片、转轴、轴头盖和密封装置，传统的金属蝶阀阀体采用金属板材或棒材为原材料,只是在材料上简单的加工出安装孔、密封槽、轴孔及通径,因此整个阀体重量比较大，轴头盖一般是盖在转轴上,起到防止雨水、灰尘等进入作用；转轴与阀体间有开关限位装置,但在运行使用过程中,管道里的急流会冲击阀片,使阀片产生转动而造成蝶阀自动关闭现象,这对运行中的设备是很大的隐患。
发明内容
本发明的目的是提供一种具有自动锁紧转轴阀片且阀体重量轻、强度好的新型蝶阀。
本发明包括阀体、阀片、转轴、轴头盖、密封件和密封槽，阀体一侧法兰面上为中间厚、边上薄的结构,其另一侧为平面结构；密封槽外上下、左右四个方向各延伸出一段加强筋；转轴轴头上端加工成六角形状,在该段六角形状部位靠顶端加工成半六角形状；轴头盖上设有与二个不同向半圆开关键对应的沉孔，套在半六角形状的转轴上,轴头盖紧固在阀体上。
通过结构改进,使轴头盖锁住转轴及阀片，提高了本蝶阀的操作安全可靠性，同时阀体的重量减轻、强度增大，节省了成本，并可减少震动和渗漏。

图2为图1的俯视图；
图3为图1的左视剖面图；
图4为本发明轴头盖图结构示意；
图5为图4的俯视图；
图6为本发明转轴结构示意图。
图中1为阀体，2为阀片，3为转轴，4为轴头盖，5为密封件，6为加强筋，7为阀体中间厚的部分，8为阀体边薄的部分，9为轴头盖上的横向半圆开关键，10为轴头盖上的纵向半圆开关键，11为安装孔，12为六角形转轴，13为半六角形转轴。
具体实施方式
如图所示，本发明所述的蝶阀包括阀体1、阀片2、转轴3、轴头盖4、密封件5和密封槽，阀体一侧的法兰面上根据机械强度原理，制作出符合受力作用规则又能减轻阀体重量——既中间厚、边上薄的结构,其另一侧为平面结构；密封槽外上下、左右四个方向各延伸出一段加强筋6，可提高阀体的强度和稳定性；如果阀体整体厚度为35mm,其边上的大部分厚度可减为12mm，可大大减轻阀体的重量；轴头盖通过铝压铸成型,其上开有二个螺栓安装孔11，轴头盖上有一个腰形沉孔,在腰形沉孔底部各有一个与横向和纵向的半圆开关键9、10对应的沉孔,分别代表蝶阀在关或开的状态，蝶阀的转轴轴头上端加工成六角形轴12,在该段六角形状部位靠顶端加工成半六角形轴13;例如转动转轴关闭蝶阀时,使轴头盖4上的横向半圆开关键9套住转轴顶端的半六角形轴13，很好的起到限位作用，螺栓通过轴头盖上的螺栓安装孔11将轴头盖4固定在阀体1上，通过锁住转轴3使转轴上的阀片2处于关闭状态，提高蝶阀的安全可靠性能；同样原理,转动转轴开启蝶阀时,将轴头盖4上的纵向半圆开关键10套住转轴顶端的半六角形轴13，转轴3上的阀片处于打开状态。
