Description

一种新型快速切断阀
技术领域
 本实用新型涉及阀门领域,尤其是一种新型快速切断阀。
背景技术
现有燃气阀技术领域,阀门的关闭都是依靠阀杆的转动来推动阀瓣上下运动,实现阀门的关闭,但是阀杆螺纹旋转直线运动速度慢,尤其是紧急状态下阀门从开启状态到闭合状态,动作时间长,容易造成介质渗漏,不能满足快速切断气源的要求。
发明内容
为克服现有技术的不足,本实用新型提供了一种新型快速切断阀,所
述一种新型快速切断阀,其特征在于,包括:阀柄1、阀盖2、孔洞3、阀杆4、阀杆栓5、弹簧6、阀瓣7、密封体8、行程插口9、密封槽10、阀瓣反顶口11、反栓密封12、阀体13,所述一种新型快速切
断阀,在阀瓣7上设有阀瓣反顶口11,其阀瓣反顶口11是从反面顶住阀瓣7,防止介质渗漏。
本实用新型的有益效果:能实现阀门的快速开闭,防止介质渗漏,
紧急状态下为切断危险源赢得了时间。
附图说明
图1为本实用新型示意图;
其中:阀柄1、阀盖2、孔洞3、阀杆4、阀杆栓5、弹簧6、阀瓣7、密封体8、行程插口9、密封槽10、阀瓣反顶口11、反栓密封12、阀体13。
具体实施方式
下面结合附图对本实用新型作详细描述:
如图1, 所述一种新型快速切断阀,在阀瓣7上设有阀瓣反顶口11,其阀瓣反顶口11是从反面顶住阀瓣7,防止介质渗漏。
