Abstract

本实用新型公开了一种双面密封阀门,该阀门包括阀体(1)、阀体(1)空腔内的阀座(3)及带有阀芯(4)的阀杆(2),阀杆(2)为两个且分别设在阀座(3)的两侧。本实用新型的两阀杆(2)的阀芯(4)同时从两侧将阀座(3)通孔密封堵住,该阀门密封效果相当于两个普通阀门的密封效果,密封效果好,所占用空间也相对较小,同时也减少了维修量,从而也降低了成本。

Description

双面密封阀门
技术领域:
本实用新型涉及阀门,特别是一种双面密封阀门。
背景技术:
目前,化工行业、特殊液体及气体的管道密封要求普遍高于其它行业,在这些行业中阀门的一般配置多采用两个阀门来控制管道密封以防泄漏。管道上阀门越多,接头就越多,泄漏可能点就越多,不仅加大了维修量,也增加了维修技术。另外,在安装上有的地方由于受场地限制无法安装两个阀门。
实用新型内容:
本实用新型的目的在于提供一种密封效果好、防泄漏、易维修的双面密封阀门。
为达到上述目的,本实用新型采用的技术方案:该阀门包括阀体、阀体空腔内的阀座及带有阀芯的阀杆,该阀杆为两个且分别设在阀座的两侧。
本实用新型双面密封阀门,使用时,开启阀座两侧的阀杆,液体或气体从阀体空腔一侧通过阀座通孔流向阀体空腔另一侧,此时该阀门为导通开启状态;相反,将阀座两侧的阀杆同时关闭,两阀杆的阀芯同时从两侧将阀座通孔密封堵住,本实用新型一个阀门密封效果相当于两个普通阀门的密封效果,密封效果好、防泄漏,所占用空间相对较小,同时也减少了维修量,从而也降低了成本。
附图说明:
图1为本实用新型结构示意图。
具体实施方式:
如图1所示,本实用新型双面密封阀门,包括阀体1、阀座3及阀杆2,该阀体1、阀座3及阀杆2均为普通的阀门部件,阀体1空腔内设有隔板5,阀座3设在隔板5中间,使用时,液体或气体从阀体1空腔一侧流进,然后通过阀座3通孔流向空腔另一侧;本实用新型的阀杆2一端带有阀芯4,另一端设有操作手柄,本实用新型在阀体1空腔垂直的方向上设有两个阀杆2,一个阀杆2的阀芯4与阀座3通孔一侧相对应,另一个阀杆2的阀芯4与阀座3通孔另一侧相对应,即两个阀杆2的阀芯4可以同时从两侧将阀座3通孔密封堵住,密封效果好。
