Abstract

一种室外消火栓,其阀体上设有自动排水阀,自动排水阀的阀体内装有阀杆,阀杆上装有弹簧座,弹簧座下设有弹簧,弹簧下端有调整螺丝,这种排水阀加工精度要求低,因此消火栓整体寿命较长,且便于维修。

Description

室外消火栓
本实用新型涉及一种消防用的室外消火栓。
现有的消火栓,其排水阀是平面密封式的,橡胶密封件易产生压缩变形磨损及吃垫现象,且受机械加工精度限制。
本实用新型的目的是提供一种排水阀加工精度要求低、寿命较长、受压力控制的室外消火栓。
本实用新型的目的是这样实现的:室外消火栓其阀体(2)的本体(8)内设有阀杆(7),阀杆(7)下连阀瓣(4),阀瓣(4)与阀座(3)密封配合,本体(8)上设有接扣(9),其特征在于阀体(2)上设有自动排水阀(5),自动排水阀的阀体(1)内装有自动排水阀阀杆(6),阀杆上装有弹簧座(10),弹簧座下设有弹簧(11),弹簧下端有调整螺丝(12),自动排水阀阀体(1)上设有排水孔。
同现有技术相比,本实用新型由于采用弹簧式自动排水阀,所以无需相应平面密封式的机械加工精度,而成为受压力控制的,所以寿命较长。维修方便。
下面结合附图详细叙述本实用新型的技术解决方案。
图1为本实用新型的结构示意图。
图2为自动排水阀的结构示意图。
如图,室外消火栓其阀体2的本体8内设有阀杆7,阀杆7下连阀瓣4,阀瓣4与阀座3密封配合,本体8上设有接扣9,阀体2上设有自动排水阀5,自动排水阀的阀体1内装有自动排水阀阀杆6,阀杆上装有弹簧座10,弹簧座下设有弹簧11,弹簧下端有调整螺丝12,自动排水阀阀体1上设有排水孔。
使用时,拉动阀杆7带动阀瓣动作启闭自动排水阀5。
