Abstract

一种闸阀,包括阀体、阀座和闸板,阀座固定在阀体上,闸板与阀座形成密封副,其特征是:在闸板与阀座的密封面上,分别嵌有整体式的环形硬质合金环块。与现有技术相比,本实用新型在构成闸阀密封副的闸板和阀座的密封面上,采用嵌入式结构设置整体式的环形硬质合金环块,使两者构成密封副,比传统结构具有更好的耐磨损、抗冲击性能,有利于提高阀门使用寿命,保证系统的可靠运行。

Description

闸阀
【技术领域】
本实用新型属于一种闸阀。
【背景技术】
应用于气力输送系统上的闸阀,其密封副不但要承受高速运动介质颗粒强力冲击,还要承受工作时密封副之间的磨损,如果有介质夹在密封副之间,磨损将更为严重。通常使用的橡胶密封件,使用寿命很短。
【发明内容】
为克服现有技术存在的上述问题,本实用新型旨在提供一种闸阀,该闸阀的密封件具有特别好的耐磨损、抗冲击优点。
实现上述目的的技术方案如下:这种结构的闸阀,包括阀体、阀座和闸板,阀座固定在阀体上,闸板与阀座形成密封副,其特征是:在闸板与阀座的密封面上,分别嵌有整体式的环形硬质合金环块。
有益效果:与现有技术相比,本实用新型在构成闸阀密封副的闸板和阀座的密封面上,采用嵌入式结构设置整体式的环形硬质合金环块,使两者构成密封副,比传统结构具有更好的耐磨损、抗冲击性能,有利于提高阀门使用寿命,保证系统的可靠运行。
【附图说明】
图1为本实用新型实施例局部剖视结构示意图;
图2为图1的俯视结构示意图。
图中:气缸1,阀体2,推柄3,弹簧4,环形硬质合金环块5,上闸板6,环形硬质合金环7,上阀座8。
【具体实施方式】
参见图1,并结合图2。本实用新型以一种双闸板闸阀为例说明,它主要由气缸1和阀体2构成,阀体2包括上阀体、中阀体和下阀体三部分,上阀体和下阀体法兰式由紧固件分别联接在中阀体的上、下侧,形成闸阀的进出输送通道。中阀体的右端与气缸1的左端经紧固件直连。在中阀体内,轴向设置推柄3,推柄3左端与气缸1内的活塞杆直连,推柄3的右端相对上阀体、下阀体的两侧,设置上闸板6和下闸板。上阀体和下阀体,以及上闸板6和下闸板为对称结构,上闸板6与上阀座8,以及下闸板与下阀座构成密封副。
本实用新型的创新点在于:在闸板与阀座的密封面上,即:上闸板6与上阀座8,以及下闸板与下阀座构成密封副的密封面上,分别嵌有整体式的环形硬质合金环块5、7,以相对设置的环形硬质合金环块构成密封副,具有诸多优点。
