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, and
Signal connector 21 and remote alarms valve control platform 22.The sensor element that signal connector 21 is used to that alarm valve to be arranged
Signal is received and is converted, and feeds back to remote alarms valve control platform 22, is controlled and is reported by remote alarms valve control platform 22
The operations such as the examination water of alert valve.
The alarm valve body 1 is divided into the system side 3 for connecting extraneous fire-fighting equipment and the extraneous spray of connection by flap 8
The water supply side 2 of water pump.Valve body 1 of alarming is interior to be equipped with a chamber for accommodating flap 8, and the top of chamber, which is equipped with a limiting stand, prevents valve
Valve 8 deviates from the limit range of chamber, and flap 8 is the structure type of an inverted trapezoidal, and top is the structure of a umbrella shaped support, its underpart
For a cylindrical spool, the interior seal chamber for being equipped with the sealing to match with spool of alarm valve body, the cooperation of spool and seal chamber
Sealed separation system side 3 and water supply side 2；When system side 3 has water flowing that the pressure of system side 3 is caused to reduce, due to water supply side 2
Pressure remained steady it is constant, at this point, the pressure of water supply side 2 be greater than system side 3 pressure, effect of the flap in the pressure difference
Under, it is moved up by promotion, the spool of flap is detached from the seal chamber in alarm valve body, since a limit is arranged at the top of chamber
Platform, flap are limited to the limit dais, and flap top is the support construction of a umbrella, packingless function, at this time alarm valve master
The system side of body is connected with water supply side, and when the anhydrous flowing of system side, system lateral pressure and water supply side pressure balance, flap exist
It under the action of self gravity, moves down, to restore to the state of sealed separation.
The system side 3 is equipped with drainpipe 4, and drainpipe 4 is connected to extraneous drainage system, and the setting examination water on drainpipe 4
Solenoid valve 9, and flow sensor 14 is set in the end of its drainpipe 4, flow sensor 14 is electrically connected in signal connector, is used for
Monitor the water size of drainpipe discharge.Water supply side 2 is provided with alarm pipeline 6, and control of the pipeline 6 by flap 8 of alarming, alarm
The internal diameter of pipeline 6 is less than the internal diameter of drainpipe 4；When flap 8 moves up, alarm pipeline 6 is opened, when flap 8 resets, pipeline 6 of alarming
It is sealed and closes by flap 8.
In order to realize being turned off manually for alarm pipeline, it is additionally provided with shut-off valve 11 on alarm pipeline 6, shut-off valve 11 keeps normal
Open state.Alarm pipeline 6 is connected with threeway 19, and two ports of residue of threeway 19 are separately connected water flow delays device 16 and throttling dress
Set 15, wherein water flow delays device 16 is the container of a barrel-like structure that can store certain water, and throttling set 15 is a undergauge
Tubular structure, internal diameter are less than the internal diameter of the alarm pipeline 6, meanwhile, throttling set 15 passes through pipeline connection drainpipe 4, and
The rear end of its connectivity points is arranged in flow sensor 14；The rear end of water flow delays device 16 is connected with alarm bell pipe 20, and alarm bell pipe 20 connects
It is connected to warning water system 18, and the alarm bell pipe 20 is equipped with the pressure switch 17 for controlling feeding spraying pump start and stop, the waterpower
Alarm bell 18 connects extraneous drainage system.When the starting of alarm valve system side fire-fighting equipment automatic fire extinguisher or fire-fighting system pipeline
Rupture generates the flowing of water flow in system side, so that system lateral pressure be caused to be less than water supply lateral pressure, flap is caused to open, supplied
Continuously continual water flow enters alarm pipeline to water, and triggering warning water system issues alarm the tinkle of bells.When residual water in alarm pipeline line
Flowing is generated because of some unexpected factors for flow or because flap is poorly sealed to generate small water flow in alarm pipeline
When amount, the water flow in pipeline of alarming is discharged by drainpipe, or is entered in water flow delays device, without generating warning water system
False alarm and pressure switch error starting, alarm pipeline is only generating endlessly water flow, while water flow is more than section
When flowing the maximum stream flow of device, after water flow is full of water flow delays device, the starting of pressure switch and the report of warning water system can be just triggered
It is alert.
The normal pressure of water supply side and system side fluctuates bring false alarm in order to prevent, and the system side 3, which is additionally provided with, is
Side bypass of uniting compensates pipe 5, and is equipped with the first pressure sensor 10 being electrically connected with signal connector 21 at its end；The water supply side
2 are additionally provided with water supply side bypass compensation pipe 7, and are equipped with the second pressure sensor 12 being electrically connected with signal connector 21 at its end.
The system side bypass compensation pipe 5 bypasses compensation pipe 7 with the water supply side and is connected by compensator 13, due to extraneous fire-fighting system
Uniting, the pipeline connected is longer, and fire-fighting equipment is excessive, and certain pressure oscillation, the benefit can be more or less generated in fire-fighting system
When pressure oscillation can be generated in fire-fighting system by repaying device 13, it is connected to the water supply side and system side of alarm valve, makes valve supply water of alarming
Side and system side keep pressure balance, effectively eliminate the influence of fire-fighting system normal pressure fluctuation, thus avoid alarm valve because
The false alarm of the fluctuation of normal pressure caused by fire-fighting system and generation.
The remote alarms valve control platform 22 is additionally provided with for showing 10 pressure value of first pressure sensor, described
The display panel of 12 pressure value of second pressure sensor, 14 flow value of the flow sensor, the remote alarms valve control are flat
Platform 22 is equipped with the switch button switched for controlling the examination water solenoid valve 9, the control in the remote alarms valve control platform 22
SIMATIC S7-200 is selected but be not limited to device processed, and button reality is arranged by remotely starting switch button and automatic detecting period
The automatic waterproof test of all alarm valves, substantially reduces manpower spent by artificial outflow test and time in now building, meanwhile,
For heavy construction, automatic sprinkling fire-extinguishing fire-fighting system is complex, and alarm valve is more, it is possible to prevente effectively from manually trying water test
Omission the pressure value and water flow of water test are tried shown by display panel to eliminate the risk hidden danger of fire-fighting system,
It tries whether water test succeeds for evaluating it, provides scientific and effective foundation for the examination water test of fire-fighting system.
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.
