Description
Technical field
This utility model belongs to fire-extinguishing apparatus technical field, particularly relates to a kind of alternation of wetting and drying and runs hydrant system.
Background technology
Fire hydrant is a kind of fixing fire extinguishing supply equipment, and it includes fire water-supply pipe network and fire hydrant box, is arranged on fixing
Position, and have significantly mark, have bolt mouth, water band, hydraulic giant and fire hydrant button in case, be that a kind of convenient effective fire-fighting sets
Execute.Fight a fire for specialty fire fighter and field personnel when a fire, initial fire disaster is puted out a fire to save life and property and the intensity of a fire
Control to play very important effect.Generally it is not less than 4 DEG C, and the place of not higher than 70 DEG C at indoor environment temperature, uses more
Wet fire hydrant system.But when indoor environment temperature is less than 4 DEG C, and in fire water-supply pipe, water-filling there will be the danger of frost, environment
Temperature is higher than 70 DEG C, can make water-filling vaporization aggravation in pipe, be susceptible to destroy pipeline and the danger of adnexa.In addition freeze and vaporize
All can reduce the water supply capacity of fire hydrant pipeline, and then cause reduction or the disappearance of whole system extinguishing ability.Therefore indoor environment
Temperature is less than 4 DEG C, or the place higher than 70 DEG C, preferably uses dry type fire to tie system.In subway, winter environment temperature is less than 4 DEG C, its
His ambient temperature in season, between 4 DEG C～70 DEG C, preferably uses alternation of wetting and drying to run hydrant system.
Summary of the invention
This utility model provides one to operate steadily for solving technical problem present in known technology, safe and reliable,
Easy maintenance and in being applicable to subway the alternation of wetting and drying of fire-fighting system run hydrant system.
This utility model is adopted the technical scheme that by solving technical problem present in known technology:
Alternation of wetting and drying operation hydrant system, the interval fire hydrant pipeline being connected with station water fire fighting system including two ends,
It is arranged on the fire hydrant on fire hydrant pipeline, it is characterised in that: also include quick-acting valve, maintenance valve, automatic exhaust steam valve, peace
Full valve and drain valve, described interval fire hydrant pipeline circularizes layout, and described quick-acting valve is arranged on station and disappears near interval
The end of fire bolt pipeline, the interval fire hydrant pipeline between described every 2～3 fire hydrants arranges maintenance valve, disappears in interval
Being provided with multiple automatic exhaust steam valve on fire bolt pipeline, described relief valve is arranged in the middle part of interval fire hydrant pipeline, and disappear fire in interval
The minimum position of bolt pipeline is provided with drain valve.
This utility model can also adopt the following technical scheme that
Every 200m, one automatic exhaust steam valve is installed on described interval fire hydrant pipeline.
This utility model has the advantage that with good effect: owing to this utility model uses technique scheme, the most logical
Crossing and use this alternation of wetting and drying to run hydrant system, in opening each subway annual spring, station fire hydrant pipe ends is fast
Speed opens and closes valve, and being full of water in making fire hydrant pipeline can run according to wet type fire extinguishing system；When winter temperature is in low temperature state
Time, close this quick-acting valve, open the drain valve of interval fire hydrant pipeline lowest part, the water in interval fire hydrant pipeline is put
Empty by interval pump eliminating, opening and closing the fire hydrant pipeline after valve is dry type, can use dry fire hydrant system.Due to the fire that disappears winter
In bolt pipeline anhydrous, the hidden danger that fire hydrant pipeline freezes will not occur, and fire hydrant pipeline is without carrying out isothermal holding, more will not
Produce water dripping phenomenon.This hydrant system operates steadily, safe and reliable, simple and convenient operation and maintenance, therefore is highly suitable for subway and disappears
Anti-system.

Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate
Accompanying drawing describes in detail as follows:
Referring to Fig. 1, alternation of wetting and drying runs hydrant system, the interval being connected including two ends with station water fire fighting system 8
Fire hydrant pipeline 7 and the fire hydrant 6 being arranged on fire hydrant pipeline, described fire hydrant pipeline arranges one every 45～50m
Fire hydrant.This hydrant system also includes quick-acting valve 1, maintenance valve 2, automatic exhaust steam valve 3, relief valve 4 and drain valve 5,
Described interval fire hydrant pipeline circularizes layout.Described quick-acting valve 1 is arranged on the station end near interval fire hydrant pipeline
Portion, enables each interval fire hydrant pipeline from adjacent acquirement water source, two subway stations, undertakes two by each subway station
1/2 calculating of adjacent interval, during fire, the filling time of fire hydrant pipeline can shorten further.
Maintenance valve 2 is set on the interval fire hydrant pipeline between described every 2～3 fire hydrants, it is ensured that maintenance fire hydrant
Time, the quantity that fire hydrant disables will not be too many.
Being provided with multiple automatic exhaust steam valve 3 on interval fire hydrant pipeline, its effect is to get rid of rapidly when breaking out of fire
Gas in fire hydrant pipeline, makes water be full of fire hydrant pipeline.Owing to Metro Design circuit is substantially low interval, high station, interval
Two, tunnel is connected with station, middle low, two head heights, and during breaking out of fire, the system of interval fire hydrant pipeline is entered from station, two ends
Water, automatic exhaust steam valve relies primarily on system water pressure and drives away the gas in fire hydrant pipeline.In the present embodiment, automatic exhaust steam valve removes
To arrange at the middle part of interval fire hydrant pipeline, also to arrange along journey, the single track line of the most about 1km length should be at least provided with
5, every 200m, one automatic exhaust steam valve is installed.
Described relief valve 4 is arranged in the middle part of interval fire hydrant pipeline, in order to eliminate the danger of fire hydrant pipeline superpressure.
It is provided with drain valve 5 at the interval minimum position of fire hydrant pipeline, closes fire hydrant pipe ends when winter approached
Quick-acting valve 1, open the drain valve 5 at interval fire hydrant pipeline minimum point, the water in fire hydrant pipeline is vented and by
Pumping plant is got rid of.
This alternation of wetting and drying runs the automatically controlled setting of hydrant system: while the other button of interval fire hydrant is pressed, FAS system is beaten
Open the quick-acting valve before the headwall of station, two ends, interval, place, start the fire hydrant pump at station, two ends.Station control room is remotely controlled
Station processed leads to interval quick-acting valve, and shows work and malfunction.
The work process that alternation of wetting and drying runs hydrant system is as follows:
When breaking out of fire, the fire alarm system of subway station or control centre receives the report for police service signal, will open quickly
Open and close valve 1, make the water of subway station Fire Fighting Pumps pipe network rapidly to the fire hydrant pipeline input in corresponding station or interval, fire hydrant
In pipeline, air is discharged rapidly by automatic exhaust steam valve 3 under the effect of hydraulic pressure, can realize fire hydrant pipeline at short notice
It is changed into rapidly wet type fire extinguishing system by dry type fire extinguishing system, then picks out rotary hose from fire hydrant mouth and hydraulic giant reaches fire extinguishing
Purpose.
The embodiment that this utility model accompanying drawing describes is exemplary, is only used for explaining this utility model, and is not understood that
For to restriction of the present utility model.
