The invention relates to a high strength butterfly valve, comprising a valve body, a valve plate and the valve seat, the valve seat coaxially installed in the valve body, the valve seat valve plate installed coaxial system, outer surface of the valve body are reinforced with annular bulge, the reinforcing rib width less than the width of the valve body, the valve board both ends of the surface integral transverse rib guide are evenly spaced parallel intervals, the outer edge of the axial ribs strengthen evenly spaced a plurality of arc-shaped grooves. Through the reinforcement on the outer edge of the valve body, there are multiple arc grooves on the outer edge of the reinforcing rib uniformly spaced on the outer edge, which not only improves the rigidity of the valve body, but also reduces the cost of the valve body. A plurality of guide tendons are made on the valve plate to prevent the medium from hanging on the side of the valve plate so as to influence the velocity of the valve. Through the design of the nameplate protruding, the nameplate is installed conveniently, quickly and firmly. The invention is simple in structure, scientific and reasonable in design and ingenious in conception, and has the value of extensive popularization and application.
【技术实现步骤摘要】
高强度蝶阀
本专利技术属于阀门领域,尤其是一种高强度蝶阀。
技术介绍
大口径蝶阀的蝶板安装于管道的直径方向。在蝶阀阀体圆柱形通道内,圆盘形蝶板绕着轴线旋转,旋转角度为0°-90°之间,旋转到90°时,阀门则全开状态。目前,特别是在大中型口径、中低压力的使用领域,蝶阀将会成为主导的阀门形式。大口径蝶阀对其阀体的刚度要求较高,传统的做法是直接加大阀体的厚度,这样大大地提高了阀体的成本。当管道内的介质通过蝶阀时,尤其是粘稠介质,经常会挂在碟板上,影响管道的流速。经检索,发现一篇与本专利内容相关的专利文献,名称为:一种蝶阀的阀体结构,公告号:CN102996826A,包括阀体、位于阀体内的蝶板,其特征在于:所述的阀体内设有若干圈筋,所述的阀体为铸钢件,所述的蝶板上设有导流片;导流片为弧线形,两端均固定于蝶板且凸出于蝶板表面。通过对比,上述专利公开文献与本专利申请在技术方案上有较大不同。
技术实现思路
本专利技术的目的在于克服现有技术的不足,提供一种高强度蝶阀。本专利技术的方案是这样实现的:一种高强度蝶阀,包括阀体、阀板以及阀座,所述阀座同轴安装在阀体内,该阀座内同轴安装阀板,所述阀体的外缘表面一体制有环形凸起的加强筋,该加强筋的宽度小于阀体的宽度,所述阀板的两端面一体横向均匀间隔制有平行间隔设置的导向筋。而且,所述加强筋的外缘轴向均匀间隔制有多个弧形凹槽。而且,所述导向筋的两端部向外侧延伸。而且,所述阀体上部的圆柱连接部一侧一体制有矩形铭牌凸起。本专利技术的优点和积极效果是:通过在阀体的外缘制有加强筋,该加强筋的外缘轴向均匀间隔制有多个弧形凹槽,该加强筋不仅提高了阀体 ...
