Description
Technical field
Fire-fighting domain is the utility model is related to, 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, it has a fire fighting truck intake and two
A hand tengential belt interface, internal flap axis is cut-off type structure, once there is fire behavior, opens end cap, connects rotary hose turn, unlatching disappears
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, since 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, carrys out hidden trouble to safety belt.
Chinese patent CN20612819u discloses a kind of Outdoor Fire Hydrant, including body is installed on the water flow switch in body
And the bolt that lid is located on body emits, the water flow switch is equipped with honeywell switch sensor, and internal relevant configuration, this is practical
New main function is the relevant information for allowing administrative staff to obtain fire hydrant, is quickly taken measures, and reduces water money to greatest extent
Source wastes, but it does not possess and prevents top foreign matter from diffusing to lower part function opening anhydrous stream mode.
Utility model content
The purpose of this utility model is exactly to provide a kind of non-proliferation to overcome the problems of the above-mentioned prior art
Fire hydrant.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of fire hydrant of non-proliferation, it is dirty to prevent from poisoning, including body and the bolt body that is arranged on body, institute
The bolt body stated sets the hand tengential belt interface for being stamped end cap, and transmission is equipped with successively from top to bottom inside the body and bolt body
Axis, flap and guide rod, the flap at body inner flow passage with being equipped with valve seat, it is characterised in that the fire hydrant further includes
Bogie and spring, transmission shaft lower part are fixedly connected for a T-shaped screw rod 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.
The flap is an ampuliform structure, and top bottleneck is hollow, is transported up and down in bottleneck to be oriented to transmission shaft lower end
Dynamic, lower part body is correspondingly arranged with valve seat.
The body inner wall is additionally provided with to prevent the guiding rib that bogie rotates.
The body and bolt body are by bolt or hit driffractive ring and be fixedly connected.
When body is fixedly connected with bolt body by hitting driffractive ring, the transmission shaft is made of bolt figure and body section, institute
The bolt figure and body section stated are connected with each other by shaft coupling to be driven.
The fire hydrant further includes the fixed frame being arranged at body and bolt body contact surface, and the fixed frame center, which is equipped with, to be used
To pass through the centre bore of transmission shaft.
The position of the shaft coupling is higher than fixed frame.
Compared with prior art, the utility model has the following advantages：
First, it is simple in structure, cost is low：The utility model only with the addition of spring, bogie compared with original fire hydrant
It is simple and convenient etc. structure, transformation.
2nd, security is reliable, prevents foreign matter from spreading：The utility model can effectively be compressed downwards by spring flap with
Valve base sealing, it is therefore prevented that malicious, the dirty infiltration to city planting ductwork, is effectively protected water quality safety, with existing anti-foreign matter fire-fighting
Bolt is compared, and the spring of the utility model is located in body, and away from hand tengential belt interface, it is anti-can effectively to prevent that artificial destruction from losing
Diffusion function.
3rd, anticollision well blowout preventing：The utility model is by setting the transmission shaft of two-part, in body top energy after being knocked
Phenomenon of spraying water will not occur for enough automatic separately, inside body still seal.

Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As illustrated in fig. 1 and 2, the utility model provides a kind of non-proliferation fire hydrant, there is two kinds of forms, including plain edition (figure
1) and crash-proof (Fig. 2), including body, bolt body, end cap, transmission shaft, bogie, spring, flap, valve seat, guide rod, anticollision
Type fire hydrant further includes fixed frame, hits driffractive ring and shaft coupling.
End cap is installed on the hand tengential belt interface of bolt body, and transmission shaft is fixed between bolt body center and flap, driving
Frame is located at transmission shaft lower part, and in body bosom, between transmission shaft lower part bogie and flap, flap is located at spring
Transmission shaft lower part, valve seat top, valve seat are fixed on body inner ring, and guide rod is fastened on flap lower part；
Fixed frame is fixed on body top, hits driffractive ring and is fixed on bolt body lower part and body top junction, shaft coupling is located at
On fixed frame crash-proof.
Transmission shaft lower part is T-shaped screw rod, bogie can be promoted to move up and down, and prevented by the guiding rib on the inside of body
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 transmission shaft lower part, not screw thread engagement.
The 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 transmission shaft separates automatically at shaft coupling, and fixed frame can be fixed on the transmission shaft of lower part, prevents it from deviating from bolt
Body, is not damaged except hitting driffractive ring damage other parts, and can effectively prevent blowout phenomenon.
The non-proliferation function of the utility model by acting realization as follows：
Flap is not threadedly coupled with transmission shaft, and transmission shaft lower end is only used as flap lower part and installs guide rod by being led among body
It is oriented to change, is threadedly coupled among bogie for T-shaped screw thread and axis moving axis, anti-rotation is to lean on the guiding rib of body both sides, spring pocket
In transmission shaft lower part, between bogie and flap.When fire hydrant standard-sized sheet, driver is in topmost, if without water
Flow regime, then flap be automatically closed 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 transmission shaft to standard-sized sheet,
Flap controls it to automatically open up under the promotion of waterpower and discharges water since bogie loses.Reach fire extinguishing purpose.After return
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 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.
