Description
Technical field
The present invention relates to fire-fighting domain, more particularly, to a kind of fire hydrant of non-proliferation.
Background technology
In fire-fighting domain, Outdoor Fire Hydrant is most commonly used national standard product, and it has a fire fighting truck intake and two
Individual hand tengential belt interface, internal flap axle is cut-off type structure, once there is the condition of a fire, opens end cap, connects rotary hose turn, unlatching disappears
Power transmission shaft lifting flap in anti-bolt top departs from valve seat, and the hydraulic giant that the water among pipe network sprays fire hose end of tape under pressure promotion is real
Apply fire extinguishing.Fire extinguishing terminates closing flap and blocks current, removes water hose joint, covers end cap, fire extinguishing terminates.
But if end cap is opened, end cap is covered again after foul, poisonous substance have been put into bolt body, and then opening flap will
Produce water dissolving foul, poisonous substance and diffuse into pipeline, because the fire_fighting pipe network in current China's major part city is from life
Branched away on grid, so contaminated fire water diffuses to life pipe soon if not filling diversion preventer
Net, carry out hidden trouble to safety belt.
Chinese patent CN20612819u discloses a kind of Outdoor Fire Hydrant, including key is installed on the water flow switch in key
And the bolt that lid is located on key emits, the water flow switch is provided with honeywell switch sensor, and internal relevant configuration, this invention
Main function be allow administrative staff obtain fire hydrant relevant information, quickly take measures, to greatest extent reduce water resource wave
Take, but it does not possess and prevents top foreign matter from diffusing to bottom function opening anhydrous stream mode.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of fire-fighting of non-proliferation
Bolt.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of fire hydrant of non-proliferation, it is dirty to prevent from poisoning, including key and the bolt body that is arranged on key, institute
The bolt body stated sets the hand tengential belt interface for being stamped end cap, and transmission is sequentially provided with from top to bottom inside described key and bolt body
Axle, flap and guide rod, described flap at key inner flow passage with being provided with valve seat, it is characterised in that the fire hydrant also includes
Bogie and spring, power transmission shaft bottom are that a T-shaped screw rod is fixedly connected with bogie, and lower end is stretched into flap and is oriented to, described
Spring be set in outside T-shaped screw rod, upper and lower ends are connected with bogie and flap respectively.
Described flap is an ampuliform structure, and top bottleneck is hollow, is transported up and down in bottleneck to be oriented to power transmission shaft lower end
Dynamic, bottom body is correspondingly arranged with valve seat.
Described key inwall is additionally provided with to prevent the guiding rib that bogie rotates.
Described key and bolt body are by bolt or hit driffractive ring and be fixedly connected.
When key is fixedly connected with bolt body by hitting driffractive ring, described power transmission shaft is made up of bolt figure and key section, institute
The bolt figure and key section stated are connected with each other by shaft coupling to be driven.
The fire hydrant also includes being arranged on the fixed mount at key and bolt body contact surface, and described fixed mount center, which is provided with, to be used
With through the centre bore of power transmission shaft.
The position of described shaft coupling is higher than fixed mount.
Compared with prior art, the present invention has advantages below：
First, it is simple in construction, cost is low：It is of the invention compared with original fire hydrant, only with the addition of spring, bogie etc. knot
Structure, transformation are simple and convenient.
2nd, security is reliable, prevents foreign matter from spreading：The present invention effectively can compress flap and valve seat downwards by spring
Sealing, it is therefore prevented that malicious, the dirty infiltration to city planting ductwork, water quality safety is effectively protected, with existing anti-foreign matter fire hydrant phase
Than spring of the invention is located in key, away from hand tengential belt interface, can effectively prevent artificial destruction from losing non-proliferation work(
Energy.
3rd, anticollision well blowout preventing：Power transmission shaft of the invention by setting two-part, can be certainly on key top after being knocked
Dynamic to separate, still phenomenon of spraying water will not occur for sealing inside key.

Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As illustrated in fig. 1 and 2, the present invention provides a kind of non-proliferation fire hydrant, there is two kinds of forms, including plain edition (Fig. 1) and
Crash-proof (Fig. 2), disappear including key, bolt body, end cap, power transmission shaft, bogie, spring, flap, valve seat, guide rod, crash-proof
Anti- bolt also includes fixed mount, hits driffractive ring and shaft coupling.
End cap is installed on the hand tengential belt interface of bolt body, and power transmission shaft is fixed between bolt body center and flap, driving
Frame is located at power transmission shaft bottom, and in key bosom, between power transmission shaft bottom bogie and flap, flap is located at spring
Power transmission shaft bottom, valve seat top, valve seat are fixed on key inner ring, and guide rod is fastened on flap bottom；
Fixed mount is fixed on key top, hits driffractive ring and is fixed on bolt body bottom and key top junction, shaft coupling is located at
On fixed mount crash-proof.
Power transmission shaft bottom is T-shaped screw rod, bogie can be promoted to move up and down, and prevented by the guiding rib on the inside of key
Rotation, the keying of flap are jointly controlled by pressure difference above and below bogie, spring and flap, the flap top bottleneck endoporus of vase-like
To be oriented to for the T-shaped end of thread in power transmission shaft bottom, screw thread does not engage.
The power transmission shaft of crash-proof fire hydrant is formed by upper and lower two, and is docked by shaft coupling, once fire hydrant is hit, is hit
Driffractive ring is broken, and power transmission shaft separates automatically at shaft coupling, and fixed mount can be fixed on the power transmission shaft of bottom, prevents it from deviating from bolt
Body, do not damaged except hitting driffractive ring damage other parts, and can effectively prevent blowout phenomenon.
The non-proliferation function of the present invention by acting realization as follows：
Flap is not threadedly coupled with power transmission shaft, and power transmission shaft lower end is only used as flap bottom and installs guide rod by being led among key
It is oriented to change, is threadedly coupled among bogie for T-shaped screw thread and axle moving axis, anti-rotation is to lean on the guiding rib of key both sides, spring housing
In power transmission shaft bottom, between bogie and flap.When fire hydrant standard-sized sheet, driver is in topmost, if without water
Flow regime, then flap close automatically under the action of the spring, prevent under Medium Diffusion above in facial canal net.
As shown in figure (3a) and (4a), figure is that fire extinguishing terminates after closing, and waits use state next time --- at this moment at flap
Have the pressure of pipe network below closure state, flap, above no pressure, end cap covers.
As shown in figure (3b) and (4b), figure is that end cap opening connects rotary hose and rotates in an anti-clockwise direction power transmission shaft to standard-sized sheet,
Flap is controlled it to automatically open up under the promotion of waterpower and discharged water because bogie loses.Reach fire extinguishing purpose.Returned after end
To the state of figure (3a) and (4a).
As shown in figure (3c) and (4c), figure is non-proliferation state, once in the closed state, there is lawless people to open end cap
Be put into foul, poisonous substance, then cover end cap open power transmission shaft rotate counterclockwise flap and it is crack discharge water, once punching is full in bolt body
Water, current stop, and pressure balance, flap is closed rapidly under the promotion of spring, prevent foul, poisonous substance in bolt body from diffusing to fire-fighting
Pipe network.
