Specific embodiment
The invention will be further described with embodiment for explanation with reference to the accompanying drawing, and mode of the invention includes but not only limits
In following embodiment.
It is as shown in Figs. 1-2: a kind of alarm valve with data feedback and automatic inspection function, including alarm valve body 1, it is described
Alarm valve body 1 is divided into the system side 3 for connecting extraneous fire-fighting equipment by flap 8 and connects the water supply side 2 of extraneous water pump.
The system side 3 is equipped with drainpipe 4 and system side bypass compensation pipe 5, and the water supply side 2 is equipped with alarm 6 He of pipeline
Water supply side bypass compensation pipe 7, the system side bypass compensation pipe 5 and water supply side bypass compensation pipe 7 pass through 13 phase of compensator
Connection, since the pipeline of extraneous fire-fighting system connection is longer, fire-fighting equipment is excessive, and one can be more or less generated in fire-fighting system
Fixed pressure oscillation, when the compensator 13 can generate pressure oscillation in fire-fighting system, be connected to alarm valve water supply side and
System side makes alarm valve water supply side and system side keep pressure balance, effectively eliminates the influence of fire-fighting system normal pressure fluctuation,
The false alarm generated to avoid alarm valve because of the fluctuation of normal pressure caused by fire-fighting system.
The end of the water supply side bypass compensation pipe 7 is equipped with second pressure sensor 12, the system side bypass compensation pipe 5
End be equipped with first pressure sensor 10, the drainpipe 4 be equipped with examination water solenoid valve 9, and at its end be equipped with flow sensing
Device 14, the drainpipe 4 connect extraneous drainage system, and the alarm pipeline 6 controls its switch by the flap 8, works as alarm
The starting of valve system side fire-fighting equipment automatic fire extinguisher or fire-fighting system line fracture generate the flowing of water flow in system side,
To cause system lateral pressure to be less than water supply lateral pressure, flap is caused to open, the continuous continual water flow that supplies water enters alarm pipe
Road, triggering warning water system issue alarm the tinkle of bells.
The alarm pipeline 6 is equipped with shut-off valve 11, and the shut-off valve is normally open, and the shut-off valve 11 is connected with threeway
19, the remaining two-port of the threeway 19 is separately connected water flow delays device 16 and throttling set 15, and the throttling set 15 is connected to institute
Drainpipe 4 is stated, the internal diameter of the drainpipe 4 is greater than the internal diameter of the alarm pipeline 6, and the internal diameter of the throttling set 15 is less than institute
The internal diameter for stating alarm pipeline 6, when in alarm pipeline line remaining water flow generate because of some unexpected factors flowing or because
Flap it is poorly sealed alarm pipeline in generate small water flow when, alarm pipeline in water flow by drainpipe discharge,
Or enter in water flow delays device, without generating the false alarm of warning water system and the error starting of pressure switch, alarm pipeline is only
Have and generating endlessly water flow, while when water flow is more than the maximum stream flow of throttling set, water flow is full of water flow delays device
Afterwards, the starting of pressure switch and the alarm of warning water system can just be triggered.
16 rear end of water flow delays device is connected with alarm bell pipe 20, and the alarm bell pipe 20 is connected with warning water system 18, and institute
Alarm bell pipe 20 is stated equipped with the pressure switch 17 for controlling extraneous water pump start and stop, the warning water system 18 connects extraneous draining system
System, the first pressure sensor 10, the second pressure sensor 12, the examination water solenoid valve 9 and the flow sensing
Device 14 is respectively connected with signal connector 21, and the signal connector 21 connects remote alarms valve control platform 22, the long-range report
Alert valve control platform 22 is equipped with for showing 10 pressure value of first pressure sensor, 12 pressure of second pressure sensor
The display panel of value, 14 flow value of the flow sensor, the remote alarms valve control platform 22 are equipped with described for controlling
The switch button that water solenoid valve 9 switchs is tried, the controller in the remote alarms valve control platform 22 is selected but is not limited to
SIMATIC S7-200 is arranged button and realizes all alarms in building by remotely starting switch button and automatic detecting period
The automatic waterproof test of valve substantially reduces manpower spent by artificial outflow test and time, meanwhile, for heavy construction, certainly
Dynamic sprinkling fire fire-fighting system is complex, and alarm valve is more, it is possible to prevente effectively from the manually omission of examination water test, to eliminate
The risk hidden danger of fire-fighting system tries the pressure value and water flow of water test shown by display panel, tries water for evaluating its
Whether test succeeds, and provides scientific and effective foundation for the examination water test of fire-fighting system.
The working principle of alarm valve of the invention:
When the fluctuation of the normal pressure of extraneous fire-fighting system: compensator is connected to alarm valve under the action of pressure oscillation
Water supply side and system side make alarm valve water supply side and system side keep pressure balance, effectively eliminate fire-fighting system positive normal pressure Reeb
Dynamic influence, to avoid alarm valve because of the false alarm that normal pressure caused by fire-fighting system fluctuates and generates.
When having a small amount of water flow in pipeline of alarming: remaining water flow is produced because of some unexpected factors in alarm pipeline line
When life is flowed or generates small water flow in pipeline of alarming because of flap is poorly sealed, the water flow in pipeline of alarming is led to
Drainpipe discharge is crossed, or is entered in water flow delays device, without generating the false alarm of warning water system and accidentally opening for pressure switch
It is dynamic, while the data feedback of flow sensor, to remote alarms valve control platform, control platform is according to by flow sensor
The duration of uninterrupted and flow, determine whether alarm valve is in normal working condition, if flow sensor is supervised
Continual small flow is surveyed, then shows that flap is poorly sealed, needs to carry out maintenance and inspection to alarm valve flap.
When alarm valve normally tries water or extraneous fire-fighting automatic sprinkling fire-extinguishing equipment triggering starting: system side generates water flow
Flowing, cause the pressure of system side to be less than the pressure of water supply side, this is that triggering flap is opened, and is not generated in a steady stream not in alarm pipeline
Disconnected water flow, shut-off valve are normally open, and water flow is by shut-off valve, since the pipeline of connection drainpipe is equipped with throttling dress
It sets, and throttling set internal diameter is less than the internal diameter of alarm pipeline, water flow cannot be discharged completely from drainpipe by throttling set, be forced
Part water flow is flowed toward alarm bell direction in water, and after water flow is full of water flow delays device, water flow continues flowing and opens to trigger pressure
It closes, controls the unlatching of extraneous water pump, while triggering warning water system alarm.
Above-described embodiment is only one of the preferred embodiment of the present invention, should not be taken to limit protection model of the invention
It encloses, as long as that in body design thought of the invention and mentally makes has no the change of essential meaning or polishing, is solved
The technical issues of it is still consistent with the present invention, should all be included within protection scope of the present invention.
