Description

一种弹性密封闸阀
技术领域
本实用新型涉及一种阀门,尤其涉及一种弹性密封闸阀。 
背景技术
众所周知,闸阀是一种常用的阀门,一般包括阀体、阀杆、闸板、阀盖等,阀盖与阀体固定连接,阀杆上设有密封填料,阀杆与闸板传动连接,闸阀在管道上主要作切断、节流、分配和改变介质流动方向用。现有技术的闸板由实心金属材料制成,本体不具有弹性,造成密封效果不好。为了提高密封效果,往往采用在闸板的外面包设橡胶,但橡胶又存在不耐用的缺点。 
发明内容
本实用新型所要解决的技术问题是克服现有技术的不足,提供一种密封效果好又耐用的弹性密封闸阀。 
本实用新型解决上述技术问题所采用的技术方案是:一种弹性密封闸阀,包括阀盖、阀体、阀杆和闸板,阀盖与阀体固定连接,阀杆上设有密封填料,阀杆与闸板传动连接,所述的闸板的上下端开设有使闸板的密封面具有弹性的凹槽。 
本实用新型的有益技术效果是:由于闸板的上下端开设有使 闸板的密封面具有弹性的凹槽,可使密封面产生微量的弹性变形,达到更好的密封效果,而且密封面为硬密封,具有耐磨、使用寿命长的优点。 
附图说明
图1为本实用新型的结构示意图; 
具体实施方式
下面结合附图和具体实施例对本实用新型作进一步描述: 
如图1所示,一种弹性密封闸阀,包括阀盖6、阀体1、阀杆5和闸板3,阀盖6与阀体1固定连接,阀杆5上设有密封填料7,阀杆5与闸板3传动连接,所述的闸板3的上下端开设有使闸板3的密封面4具有弹性的凹槽9。 
所述的闸板3的密封面4和阀体1的密封座2设有耐腐耐磨耐高压的硬合金层8。 
所述的硬合金层8为司太立合金,喷焊在密封面4和密封座2上。 

Claims (3)
