Description

一种圆管翻板阀
技术领域
本发明涉及一种圆管翻板阀。
背景技术
目前一般大型的船舶、工况、粮食、冶金等行业的工业企业会使用到翻板阀，它一般是安装在通风或者除尘管道上，而现有翻板阀使用的方管，例如专利号为“CN206377333U”、名称为“一种手动多叶翻板阀”，当将这类翻板阀在现场使用时，由于抽风机或者除尘器接口为圆形，所以这类方管翻板阀需要另外量翻板阀两端接上天圆地方接头，而增加天圆地方接头不仅提高企业成本，也降低安装效率。
发明内容
本发明要解决的技术问题是提供一种圆管翻板阀，不仅可以直接与圆形接管对接，而且翻板受风阻小，开启方便，过风面积大。
为了解决上述问题，本发明要解决的技术方案为：
一种圆管翻板阀，包括圆管，圆管两端连接法兰，圆管中心设有支撑座，支撑座通过多根筋条连接圆管内壁，在支撑座与圆管内壁之间设有多块三角形翻板，各块翻板是绕着支撑座轴线均匀分布，各块翻板两端分别通过一根转轴与支撑座和圆管轴连接，在与圆管轴连接的各根转轴一端均安装有摇臂，各摇臂通过安装在圆管外的联动机构连接；所述联动机构到多根连杆，各根连杆设置各摇臂之间，连杆两端分别通过万向球头与连杆两端摇臂连接，还包括固定连接在圆管上的支架，支架内轴连接有传动轴，传动轴上端连接传动机构，下端与转轴固定连接。
所述传动机构包括固定安装在支架上壳体，在壳体内安装有蜗轮蜗杆机构，在壳体外安装有气动执行机构，蜗轮蜗杆机构两端分别与气动执行机构和传动轴连接。
在各块翻板一端均固定连接有挡片，当各块翻板将阀门封闭时，相邻两块翻板之间，其中一块翻板上的挡片贴在另外一块翻板上。
所述连杆为六棱柱形，连杆与万向球头之间是采用螺纹连接。
本发明的技术效果为：使用时，联动机构驱动各块翻板以支撑座做为中心同步翻转，以实现对阀门的启闭，由于是由圆管承载各块翻板，因此能够在保证阀门具有一定有效过气面积的同时，实现翻板阀与圆形接头的对接，而且翻板受风阻小，开启方便，过风面积大；另一方面，由于是采用蜗轮蜗杆机构驱动翻板旋转，所以能够有效的的翻板回转；另一方面，翻板旋转的动力来源于气动执行机构，进而能够实现远程操控翻板阀启闭，使用起来更加安全可靠。
附图说明
下面结合附图对本发明做进一步的说明：
图1为本发明的主视图，
图2为本发明的后视图，
图3为本发明的左视图，
图4为图2中A-A处的剖面结构示意图。
图中：圆管1、法兰2、支撑座3、筋条4、翻板5、转轴6、摇臂7、连杆8、万向球头9、支架10、传动轴11、壳体12、蜗轮蜗杆机构13、气动执行机构14、挡片15。
具体实施方式
如图1到4所示，一种圆管翻板阀，包括圆管1，圆管1两端连接法兰2，圆管1中心设有支撑座3，支撑座3通过多根筋条4连接圆管1内壁，在支撑座3与圆管1内壁之间设有多块三角形翻板5，各块翻板5是绕着支撑座3轴线均匀分布，当各块转动至翻板5表面垂直于圆管1轴线时，各块翻板5刚好将支撑座3与圆管1内壁面之间的通孔封住，各块翻板5两端分别通过一根转轴6与支撑座3和圆管1轴连接，在与圆管1轴连接的各根转轴6一端均安装有摇臂7，各摇臂7通过安装在圆管1外的联动机构连接；所述联动机构到多根连杆8，各根连杆8设置各摇臂7之间，连杆8两端分别通过万向球头9与连杆8两端摇臂7连接，还包括固定连接在圆管1上的支架10，支架10内轴连接有传动轴11，传动轴11上端连接传动机构，下端与转轴6固定连接，如图3所示，相邻两根连杆8之间左右布置，使得各摇臂7与各根连杆8形成多个平行四边形传动结构，当转动传动轴11时，能够驱动各块翻板5同步、同角度旋转。
本发明的使用方法为：传动机构驱动传动轴11旋转，传动轴11通过各摇臂7和各根连杆8驱动各块翻板5同步旋转，以实现对翻板5的开启或者关闭，不仅结构简单紧凑、维修快捷方便，而后能够与圆形管接头对接。
所述传动机构包括固定安装在支架10上壳体12，在壳体12内安装有蜗轮蜗杆机构13，在壳体12外安装有气动执行机构14，蜗轮蜗杆机构13两端分别与气动执行机构14和传动轴11连接。启动执行机构可以由控制室控制，通过气动执行机构14驱动蜗轮蜗杆机构13运动，以驱动传动轴11旋转，实现对各块翻板5的旋转，由于蜗轮蜗杆机构13具有止回作用，因此能够有效的防止翻板5自主旋转，使翻板5阀使用起来更加稳定可靠。
在各块翻板5一端均固定连接有挡片15，当各块翻板5将阀门封闭时，相邻两块翻板5之间，其中一块翻板5上的挡片15贴在另外一块翻板5上。如图4所示，挡片15不仅能够将相邻两块翻板5之间的缝隙进行密封的同时，而且能够有效的防止翻板5翻转过度。
所述连杆8为六棱柱形，连杆8与万向球头9之间是采用螺纹连接。六棱柱形的连杆8可以方便扳手卡入连杆8，旋转连杆8能够对翻板5的翻转角度进行微调。
