Description

一种硬密封蝶阀
技术领域
本发明涉及阀类领域，具体属于一种硬密封蝶阀。
背景技术
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，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。蝶阀适用于发生炉、煤气、天然气、液化石油气、城市煤气、冷热空气、化工冶炼和发电环保等工程系统中输送各种腐蚀性、非腐蚀性流体介质的管道上，用于调节和截断介质的流动。
发明内容
本发明的目的是提供一种硬密封蝶阀，启闭方便迅速、省力、流体阻力小，可以经常操作，安装方便。
本发明的技术方案如下：
一种硬密封蝶阀，包括有阀体、阀杆，阀杆下部与阀体之间设有导向环，阀杆上部与阀体之间设有石墨填料，石墨填料上压置填料压盖，阀杆下端放置于固定于阀体上的底盖上，阀杆上固定连接有阀板，阀板压圈将阀板密封圈压置于阀板侧壁上，阀板密封圈与阀体内腔的凸起密封配合。
所述的阀板压圈与阀板密封圈、阀板之间联接有螺钉。
所述的填料压盖上压置有填料压板，填料压板通过填料螺栓固定连接于阀体上端。
本发明通过阀板密封圈与阀体内腔的凸起实现硬性密封接触，启闭方便迅速、省力、流体阻力小，可以经常操作，安装方便。
附图说明
图1为本发明的结构示意图。
具体实施方式
参见附图，一种硬密封蝶阀，包括有阀体1、阀杆2，阀杆2下部与阀体1之间设有导向环3，阀杆2上部与阀体1之间设有石墨填料4，石墨填料4上压置填料压盖5，阀杆2下端放置于固定于阀体1上的底盖6上，阀杆2上固定连接有阀板7，阀板压圈8将阀板密封圈9压置于阀板7侧壁上，阀板密封圈与阀体内腔的凸起密封配合，阀板压圈与阀板密封圈、阀板之间联接有螺钉，填料压盖5上压置有填料压板10，填料压板10通过填料螺栓固定连接于阀体上端。
