ZL03 2 354312.The innovations include: automatic self-closing and reliably sealed valve structure: the design of duplex valve clack with pilot valve to tackle the problem of reverse seal structured valve being difficult to be opened; an automatic drain control device to automatically drain the remaining water from the hydrant; protective plate provided between the hydrant body and the valve block to serve as a connection between the hydrant body and the valve block, which is the first one to be damaged when the ground hydrant is clashed, and prevent pulling-off of the whole above-ground part of the fire hydrant, so as to properly protect the main parts from any damage. The self-closing and reliably sealed valve now prevents drain of water, and only the damaged protective plate is needed to be replaced before immediate re-operation. Thus the repair work after clashing is very easy and simple.

其创新点为：具有能自动关闭并可靠密封的阀门结构：采用有先导阀复式结构阀瓣设计，解决反向密封结构阀门开启沉重费力的难题；设计自控排水装置，能自动排除栓体内余水；在栓体和阀体之间设计撞裂板，它既起到连接栓体和阀体的中介作用，又可在地上消火栓被撞击时率先破裂毁坏，并使露出地面的栓体不见整体脱落，有效保护各主体部件的完好无损，而此时阀门的自闭式结构可靠密封阀门阻止水源外泄，修复时只需更换损坏的撞裂板即可立即复位投入使用，使被撞后的修复工作变得十分轻松简便。
