I.e. water inlet pipe 2 and housing 3 is integrated part, thus improve between water inlet pipe 2 and housing 3 close
Feng Xing.Generally, water inlet pipe 2 is connected by ring flange is fixing with fire-fighting post 1.Preferably, enter
The bottom outside of water pipe 2 can include flange plate structure, then without additionally choosing ring flange, just
Stable connection between water inlet pipe 2 and fire-fighting post 1, improves the installation effectiveness of fire hydrant.When
So, housing 3, water inlet pipe 2 can also be set to split-type structural.
It addition, can also removably be covered with hydrant cover 6 in the upside of membrane cover 7, this
Hydrant cover 6 usually cover first connecting tube the 5, first valve, the second connecting tube 8 with
And second valve, after closing fire hydrant, hydrant cover 6 is covered in the upside of membrane cover 7,
Effectively fire hydrant can be protected.Further, can be at hydrant cover 6 and shell
Between body 3, locking piece is set, such as, theftproof lock, when opening fire hydrant, open locking piece,
Hydrant cover 6 is taken off；When closing fire hydrant, hydrant cover 6 is covered and pins locking
Part.Locking piece the anti-theft function that can play fire water, beneficially saving water resource are set.
In each embodiment above-mentioned, the outside of intake 303 can be provided with intake pipe, intake pipe
Connecting end surface be connected at intake 303, connecting end surface is the water inlet of intake pipe, water intaking
The upside of the connecting end surface of the pipe i.e. upper part of connecting end surface periphery is connected to described housing 3, even
The downside of the contact surface i.e. lower part of connecting end surface periphery is connected to water inlet pipe 2, say, that
The bore of intake pipe is likely larger than the bore of intake 303, and under shed 302 is higher than connecting end
The lowest part in face, can effectively prevent the fire water flowed out from intake 303 to be back under shed
302, it is ensured that use the reliability of fire water.Preferably, water inlet pipe 2, intake pipe and housing 3
Can be one-body molded, to ensure the sealing of fire hydrant.
Wherein, intake pipe can and vertical direction between there is certain angle of inclination, in order to
Being stably connected with between the external equipments such as intake pipe and water band, hydraulic giant, it is simple to water intaking.Certainly,
The set-up mode of intake pipe is not limited with each embodiment above-mentioned.
It addition, one or at least two intake 303 can be arranged on the sidewall of housing 3.
Preferably, can be each around circumferentially disposed three intakes 303 of housing 3 on housing 3
