Description

蝶阀弹性密封阀座
技术领域
本实用新型涉及一种蝶阀弹性密封阀座。   
背景技术
    现有技术中,阀门的阀座大都采用硬质橡胶支撑,受到压力大,形变量小,阀座会被压坏,需要经常的更换阀座。
实用新型内容
本实用新型目的是提供一种结构简单,密封性好,且形变量大的,使用寿命长的蝶阀弹性密封阀座。
本实用新型解决技术问题提供如下方案:
一种蝶阀弹性密封阀座,包括阀体,其特征在于:所述阀体内转动安装有阀板,所述阀板一侧的阀腔内壁上设有阀座槽,所述阀座槽的内壁上设有波纹槽,所述阀座槽内设有阀座,所述阀座的内部空心,且安装有弹簧,所述阀座的侧壁也是波纹形。
所述阀板的边缘为圆弧形。
    本实用新型在阀门的阀体内转动安装有阀板,且在阀板一侧的阀体上设有阀座,且阀座采用波纹槽结构,弹性特别好,可以随着阀板的挤压产生相应的形变,防止阀板被压坏。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,一种蝶阀弹性密封阀座,包括阀体1,所述阀体1内转动安装有阀板2,所述阀板2一侧的阀腔3内壁上设有阀座槽4,所述阀座槽4的内壁上设有波纹槽5,所述阀座槽5内设有阀座6,所述阀座6的内部空心,且安装有弹簧7,所述阀座6的侧壁也是波纹形。
所述阀板2的边缘为圆弧形。
