Abstract

本实用新型涉及一种闸阀,具体地说是一种密封闸阀,包括阀体、置于阀体上的阀盖,还包括阀杆、与阀杆底部连接的闸板、与阀杆顶部连接的手轮,其特征在于,阀体内腔的表面上设有密封圈。本实用新型同现有技术相比,在阀体的内腔表面上设有密封圈,能够避免了阀体内腔因长时间使用而造成腐蚀,从而提高了整个闸阀的稳定性。

Description

一种密封闸阀
[技术领域]
本实用新型涉及一种闸阀,具体地说是一种密封闸阀。 
[背景技术]
闸阀主要适用于石油化工、冶金及热电厂等管道中,主要由阀体、闸板、阀杆和阀盖组成。由于闸阀的使用频率较多,所以阀体的内腔部分经常受到化工液体的腐蚀,造成阀体受损。 
[发明内容]
本实用新型的目的是克服现有技术的不足,提供了一种抗腐蚀的密封闸阀。 
为了达到上述目的,本实用新型设计了一种密封闸阀,包括阀体、置于阀体上的阀盖,还包括阀杆、与阀杆底部连接的闸板、与阀杆顶部连接的手轮,其特征在于:阀体的内腔表面上设有密封圈。 
本实用新型同现有技术相比,在阀体的内腔表面上设有密封圈,能够避免了阀体内腔因长时间使用而造成腐蚀,从而提高了整个闸阀的稳定性。 
[附图说明]
图1为本实用新型的结构示意图。 
参见图1,1为阀体;2为闸板;3为内腔;4为阀杆;5为手轮;6为密封圈;7为阀盖。 
[具体实施方式]
现结合附图对本实用新型做进一步描述。 
如图1所示,本实用新型包括阀体1、置于阀体上的阀盖7,还包括阀杆4、与阀杆底部连接的闸板2、与阀杆顶部连接的手轮5;在阀体1的内腔3的表面上设有密封圈6。 
本实用新型同现有技术相比,阀体内腔设有密封圈,避免了阀体内腔因长时间使用而造成腐蚀,从而提高了整个闸阀的稳定性。
