Description

带限位板的法兰式蝶阀
 
技术领域
本发明涉及一种蝶阀，更确切的说是一种带限位板的法兰式蝶阀。
 
背景技术
现有技术中的蝶阀上没有限位板，在调节蝶板时用户无法判断当前蝶板所处的位置，无法快速的打开和关闭蝶阀，使用极不方便，且容易出现闭合不严密的情况，容易导致流体泄露。
发明内容
本发明主要是解决现有技术所存在的技术问题，从而提供一种带有限位柱和扇形限位板，能够快速打开和关闭蝶阀，结构简单，能够较方便的改装现有技术中的蝶阀的带限位板的法兰式蝶阀。
本发明的上述技术问题主要是通过下述技术方案得以解决的：
一种带限位板的法兰式蝶阀，所述的蝶阀包括一管路连接筒、一操作手柄、一蝶板和一转轴，所述的转轴与所述的蝶板通过螺栓连接，所述的操作手柄与所述的转轴相互垂直连接，所述的管路连接筒的两端分别设置有一连接法兰圈，所述的管路连接筒上设置有一轴套，所述的转轴与所述的轴套转动连接。
作为本发明较佳的实施例，所述的管路连接筒包括一扇形限位板，所述的扇形限位板与所述的轴套的端部固定连接，所述的扇形限位板上设置有一弧形限位孔。
作为本发明较佳的实施例，所述的蝶阀还包括一限位柱，所述的限位柱与所述的操作手柄相互垂直固定连接，所述的限位柱的另一端穿过所述的弧形限位孔布置。
因此本发明的带限位板的法兰式蝶阀的优点是，带有限位柱和扇形限位板，能够快速打开和关闭蝶阀，结构简单，能够较方便的改装现有技术中的蝶阀。
 
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明的现有技术中的带限位板的法兰式蝶阀的结构示意图；
图2为图1中的蝶阀的爆炸结构示意图；
图3为图1中的管路连接筒的立体结构示意图；
其中：
1、管路连接筒；11、连接法兰圈；12、轴套；13、扇形限位板；
2、操作手柄；3、蝶板；4、转轴；5、限位柱。
 
具体实施方式
下面结合附图对本发明的优选实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
本发明提供了一种带有限位柱和扇形限位板，能够快速打开和关闭蝶阀，结构简单，能够较方便的改装现有技术中的蝶阀的带限位板的法兰式蝶阀。
如图1、图2所示，一种带限位板的法兰式蝶阀，该蝶阀包括一管路连接筒1、一操作手柄2、一蝶板3和一转轴4，该转轴4与该蝶板3通过螺栓连接，该操作手柄2与该转轴4相互垂直连接，该管路连接筒1的两端分别设置有一连接法兰圈11，该管路连接筒1上设置有一轴套12，该转轴4与该轴套12转动连接。
如图3所示，该管路连接筒1包括一扇形限位板13，该扇形限位板13与该轴套12的端部固定连接，该扇形限位板13上设置有一弧形限位孔。
如图1、图2所示，该蝶阀还包括一限位柱5，该限位柱5与该操作手柄2相互垂直固定连接，该限位柱5的另一端穿过该弧形限位孔布置。
以上仅仅以一个实施方式来说明本发明的设计思路，在系统允许的情况下，本发明可以扩展为同时外接更多的功能模块，从而最大限度扩展其功能。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何不经过创造性劳动想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书所限定的保护范围为准。
