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.
