Description

一种降噪球阀
技术领域
本实用新型属于给排水阀门技术领域,尤其涉及一种降噪球阀。
背景技术
阀门尤其是球阀,是建筑给排水管道常用的五金件。管道在运行过程中,因水流压力流速等变化,撞击管道壁及阀门,容易生成连续性噪音,尤其是竖井中或管道中存在空气,噪音更加明显。在一些对噪音有特殊控制的场合,例如实验室、高档建筑、图书馆等,普通球阀无法达到降噪的功能。
通常,有将消音棉塞入阀球中用来降噪,但带来的问题是:消音棉会带来的二次噪音,消音棉吸水后容易造成管道堵塞。
实用新型内容
本实用新型针对上述现有技术存在的不足,提供一种降噪球阀。
本实用新型解决上述技术问题的技术方案如下:一种降噪球阀,包括球阀体、与球阀体配合的球阀盖、及在球阀体和球阀盖之间的球形阀芯,其特殊之处在于,所述球形阀芯上设有通孔,所述通孔的孔壁为凹凸面。
本实用新型的有益效果是:本实用新型的球形阀芯通孔孔壁的凹凸面使得缓冲面积增加,对水流或气流产生的缓冲作用大大提高,保证更充分吸收气体和水流带来的能量,能够明显降低水流和气流的噪音污染,结构简单,经济实惠,实用性强,尤其适用于实验室、图书馆等安静场所。
在上述技术方案的基础上,本实用新型还可以做如下改进。
进一步,所述凹凸面在通孔孔壁上成波浪形。
采用上述进一步方案的有益效果是,通过波浪形的曲折流路来增加流体介质途径的通道距离,实现流体介质的逐步减速,达到对噪音源的控制,有效降低噪音。
进一步,所述通孔内嵌有尼龙套,所述尼龙套表面均布盲孔。
采用上述进一步方案的有益效果是,盲孔能够使噪声在峰值频段形成共振,进而提高球阀的消声系数和声阻抗,增加吸声带宽。
附图说明
图1为本实用新型实施例1的结构示意图;
图2为本实用新型实施例2的结构示意图;
图中,1、球阀体;2、球阀盖;3、球形阀芯;4、通孔;5、凹凸面;6、尼龙套;7、盲孔。
具体实施方式
