,具体涉及一种适用于高压管道的蝶阀。
技术介绍
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。但是现有蝶阀主要用于低压管道,这限制了其应用范围。
技术实现思路
本技术所要解决的技术问题在于克服现有的技术缺陷,提供一种适用于高压管道的蝶阀。本技术所要解决的技术问题采用以下的技术方案来实现:一种适用于高压管道的蝶阀,包括中空圆柱形阀体,阀体一端为流体进口端,另一端为流体出口端,阀板位于阀体截面位置,阀板一面朝向阀体进口端,另一面朝向阀体出口端,阀板朝向阀体出口端一面与阀杆固定连接,阀杆一端穿过阀体侧壁,阀杆穿过阀体一端与转轮或手柄连接,其特征在于:所述阀体侧壁靠近阀板朝向出口端一面并与所述阀杆垂直位置分别设置通孔,所述通孔内壁设置内螺纹,带有外螺纹的支撑螺栓分别插入所述通孔中,从而通过支撑螺栓对阀板起进一步支撑作用。所述阀板朝向出口端一面沿阀杆两侧分别设置加强杆,加强杆一端与阀杆固定连接。所述阀体内壁沿阀杆方向设置凹槽,阀杆朝向凹槽一端插入凹槽中。本技术的有益效果为:通过在阀体侧壁与阀杆垂直方向上分别设置带有内螺纹的通孔,支撑螺栓插入所述通孔中,从而在关闭该蝶阀时,将支撑螺栓旋入阀体内,从而对阀板起进一步支撑作用,以应 ...
