Abstract

本发明涉及一种法兰式蝶阀，利用撬杆、扳手以及扳手上的支点形成杠杆，撬杆中不设有孔，扳手自孔内穿出呈剪刀状，撬杆为折线转，撬杆前端位于扳手上方，后段位于扳手下方，在同时握住撬杆和扳手尾部是，带动弹簧销拔起或插入限位孔，完成解除或限位；该限位方式只需单手操作，操作方便，有效防止误操作。

Description

一种法兰式蝶阀
技术领域
本发明涉及一种蝶阀，具体涉及一种法兰式蝶阀蝶阀。
背景技术
蝶阀又叫翻板阀，是一种结构简单的调节阀，可用于低压管道介质的开关控制的蝶阀是指关闭件（阀瓣或蝶板）为圆盘，围绕阀轴旋转来达到开启与关闭的一种阀，阀门可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动。在管道上主要起切断和节流作用。蝶阀启闭件是一个圆盘形的蝶板，在阀体内绕其自身的轴线旋转，从而达到启闭或调节的目的。蝶阀的开启通常由手轮或者扳手转动阀杆实现的，在实际使用过程中，人员误碰到手轮时容易误开蝶阀，带来不必要的后果。
发明内容
本发明的目的在于提供一种防止误操作的带限位销的法兰式蝶阀。
本发明采取的技术方案为：一种法兰式蝶阀蝶阀，包括阀体，阀体的两侧设有进、出料口，阀体内安装阀芯，阀芯的顶部安装有阀杆，阀杆自阀体顶部的阀杆孔内伸出，阀杆孔内填充有填料，阀杆孔的顶部安装有填料压盖，所述填料压盖的边缘设有一圈限位孔；阀杆的伸出端上安装有限位扳手，所述限位扳手包括扳手、撬杆以及弹簧销，扳手与撬杆平行设置，所述扳手的头部的顶面设有支点，撬杆呈折线状，撬杆前段平行设置于扳手上方，撬杆自中段向下转折倾斜延伸至扳手的下方，撬杆头部支撑于扳手的支点，弹簧销自上而下依次穿接撬杆和扳手后与限位孔配合，弹簧销的固定座安装于扳手，弹簧销伸缩端的顶部经拉环与撬杆顶面限位。
采取以上技术方案后，利用撬杆、扳手以及扳手上的支点形成杠杆，撬杆中不设有孔，扳手自孔内穿出呈剪刀状，撬杆为折线转，撬杆前端位于扳手上方，后段位于扳手下方，在同时握住撬杆和扳手尾部是，带动弹簧销拔起或插入限位孔，完成解除或限位；该限位方式只需单手操作，操作方便，有效防止误操作。
附图说明
图1为本发明的剖视图。
具体实施方式
以下结合附图对本发明的具体实施方式做进一步详述：
如图所示，一种法兰式蝶阀蝶阀，包括阀体1，阀体1的两侧设有进、出料口2，阀体1内安装阀芯3，阀芯3的顶部安装有阀杆4，阀杆4自阀体1顶部的阀杆孔内伸出，阀杆4与阀体间设有多道密封圈，阀杆孔内填充有填料5，阀杆孔的顶部安装有填料压盖6，所述填料压盖6的边缘设有一圈限位孔12；阀杆4的伸出端上安装有限位扳手，所述限位扳手包括扳手7、撬杆8以及弹簧销9，扳手7与撬杆8平行设置，所述扳手7的头部的顶面设有支点10，撬杆8呈折线状，撬杆8中部设有穿接孔11，扳手穿过所述穿接孔11，撬杆8前段平行设置于扳手7上方，撬杆8头部支撑于扳手7的支点10，撬杆8自中段向下转折倾斜延伸至扳手7的下方，弹簧销9自上而下依次穿接撬杆8和扳手7后与限位孔12配合，弹簧销9的固定座安装于扳手7，弹簧销9伸缩端的顶部经拉环13与撬杆8顶面限位。
