Description

节流截止阀
技术领域
本实用新型涉及一种截止阀,特别涉及一种节流截止阀。
背景技术
传统的截止阀由阀体、阀杆、阀瓣和控制手柄构成,阀瓣和控制手柄固定在阀杆两端,阀杆可以在阀体内上下移动,阀体内设置有流道,流道的两端分别为进流口和出流口,进流口和出流口连接处为密封口。现有的截止阀的阀瓣与阀体的密封口之间会产生磨损,进而导致密封不严密,导致泄漏,造成浪费。
发明内容
本实用新型的目的就在于提供一种结构简单,密封严密的节流截止阀,能有效解决上述问题。
为了实现上述目的,本实用新型采用的技术方案是这样的:本实用新型的节流截止阀,包括阀体、阀杆、阀瓣和控制手柄,阀瓣和控制手柄固定在阀杆两端,阀体内设置有流道,流道的两端分别为进流口和出流口,进流口和出流口连接处为密封口,所述阀瓣为倒圆台形,阀瓣上设置有密封圈,所述密封口为与阀瓣相匹配的倒圆台形,所述阀体底部开有溢出口,对应溢出口设置有底盖。
作为优选,所述阀瓣与阀杆螺纹连接。
与现有技术相比,本实用新型的优点在于:本实用新型结构简单,阀瓣与密封口的形状相同,且阀瓣上设置有密封圈,密封效果好,放置泄漏,从而达到节流的目的;阀瓣与阀杆螺纹连接,且阀体上开有溢出口,方便更换阀瓣。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
下面将结合附图对本实用新型作进一步说明。
参见图1,本实用新型的节流截止阀,包括阀体1、阀杆2、阀瓣4和控制手柄3,阀瓣4和控制手柄3固定在阀杆2两端,阀体1内设置有流道,流道的两端分别为进流口和出流口,进流口和出流口连接处为密封口5,所述阀瓣4为倒圆台形,阀瓣4上设置有密封圈6,所述密封口5为与阀瓣4相匹配的倒圆台形,所述阀体1底部开有溢出口,对应溢出口设置有底盖7,所述阀瓣4与阀杆2螺纹连接。
阀瓣4与密封口5的形状相同,且阀瓣4上设置有密封圈6,密封效果好,放置泄漏,从而达到节流的目的;阀瓣4与阀杆2螺纹连接,且阀体1上开有溢出口,方便更换阀瓣4。
