Abstract

本实用新型公开了一种闸阀,包括阀体和阀盖,阀体内设置有阀座,阀座配置有阀瓣,阀瓣设置于阀杆的下端,阀瓣内部带有空腔,阀瓣下部带有空腔的出口。本实用新型提供的闸阀的阀瓣中带有空腔,因此能够节省阀瓣的材料成本,而且空心阀瓣的重量较小,便于控制。

Description

闸阀
技术领域
本实用新型涉及一种闸阀,尤其是阀瓣的结构。 
背景技术
传统闸阀一般包括阀体和阀盖,阀体内设置有阀座,阀座配置有阀瓣,阀瓣设置于阀杆的下端,一般这些阀瓣采用实心金属制造,重量较大,控制该阀瓣所需力量较大,因此控制难度增加,而且比较耗费材料成本。 
发明内容
本实用新型所要解决的技术问题是提供一种阀瓣重量较轻且材料更加节省的闸阀。 
为此,本实用新型提供的闸阀,包括阀体和阀盖,阀体内设置有阀座,阀座配置有阀瓣,阀瓣设置于阀杆的下端,阀瓣内部带有空腔,阀瓣下部带有空腔的出口。 
本实用新型提供的闸阀的阀瓣中带有空腔,因此能够节省阀瓣的材料成本,而且空心阀瓣的重量较小,便于控制。 
附图说明
附图为本实用新型提供的闸阀的结构剖视示意图。 
具体实施方式
如图所示,本实用新型提供的闸阀包括阀体1和阀盖2,阀体1内设置有阀座3,阀座3配置有阀瓣4,阀瓣4设置于阀杆5的下端,阀瓣3内部带有空腔6,阀瓣3下部带有空腔6的出口7,阀瓣3下端的出口7主要是为了方便空心 阀瓣的制造。在本实施例中,阀瓣3呈密封面8绕阀杆中心线旋转而成的旋转体,阀座3上密封配合面与旋转体状阀瓣3匹配,这种旋转体状的阀瓣3更加便于同阀座3进行密封配合。
