Abstract

本实用新型提供一种截止阀,包括填料压板(1),填料压板(1)通过螺栓(2)与阀盖(3)连接,填料(4)分布在阀杆(5)与阀盖(3)之间,其特征在于填料压板(1)与填料(4)之间设置有填料压套(6)。本实用新型与现有技术区别在于在填料压板(1)与填料(4)之间加设一个填料压套(6),填料压套(6)与填料压板(1)构成双保险,使填料(4)的密封性进一步得到保障。

Description

截止阀
技术领域
本实用新型涉及管道控制技术领域,尤其涉及一种阀门。
背景技术
截止阀是用于截断介质流动的一类阀门,截止阀的阀杆轴线与阀座密封面垂直,通过带动阀芯的上下升降进行开断。截止阀一旦处于开启状态,它的阀座和阀瓣密封面之间就不再有接触,当它关闭时,具有非常可靠的切断动作,因而它的密封面机械磨损较小,由于大部分截止阀的阀座和阀瓣比较容易修理或更换,因此当密封元件损坏时,无需把整个阀门从管线上拆下来,这对于阀门和管线焊接成一体的场合是很适用的。
截止阀是一种完全接通或切断管路的闭路阀门,其应用广泛,常在石油、化工等行业中用于控制管路中介质流通。现有的截止阀在对填料进行密封时,一般只在填料上加盖一层填料盖,其密封性不高,在使用了一段时间后,容易出现外泄的情况。
发明内容
为了解决以上技术问题,本实用新型提供一种可以有效防止填料外泄的截止阀,包括填料压板,填料压板通过螺栓与阀盖连接,填料分布在阀杆与阀盖之间,其特征在于填料压板与填料之间设置有填料压套。
本实用新型的有益效果为:本实用新型与现有技术区别在于在填料压板与填料之间加设一个填料压套,填料压套与填料压板构成双保险,使填料的密封性进一步得到保障。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
根据图1所示,填料压板1通过螺栓2与阀盖3连接,填料4分布在阀杆5与阀盖3之间,填料4上设置有填料压套6,填料压板1覆盖在填料压套6上。填料压套6与填料压板1构成双保险,使填料4的密封性进一步得到保障。
