120 and pressure sensor 110.
It is, for example, computer to control host 100, has the data processor (not shown) for handling data.
Electronic relief valve 120 is for being embedded in wall, for carrying out pressure release to wherein side.Referring to Fig. 1, electronic let out
Pressure valve 120 includes valve body outline border 121, drop front 123 and driving device 125.
Wherein, valve body outline border 121 has installation cavity 1211,1211 phase of installation cavity for being installed on wall, valve body outline border 121
To both sides be respectively communicated with air inlet 1213 and air outlet 1215, wherein in actual installation, air inlet 1213 and air-supply
Mouth 1215 is located at the both sides of wall.Optionally, air outlet 1215 is blinds air outlet 1215, can further support valve by blinds
External frame 121, improves stability, while preventing extraneous dust from entering installation cavity 1211.Wherein, optionally, blinds air outlet
1215 is set valvular power-operated shutter air outlet 1215, and the wherein valve is electrically connected with the data processor of control host 100,
For Remote Open or blinds air outlet 1215 is closed, blinds air outlet can also be opened or closed manually by using the valve
1215, wherein this sets valvular power-operated shutter air outlet 1215 as existing apparatus, does not do specifically repeat herein.
Please refer to Fig. 2 and Fig. 3, one end of drop front 123 and valve body outline border 121 are hinged, for selectivity cover in
Air inlet 1213 is used to open or closes air inlet 1213.In the present embodiment, drop front 123 is embedded at air inlet 1213,
It is after closing air inlet 1213, side of the drop front 123 far from installation cavity 1211 is located at valve body outline border with air inlet 1213
The side wall of 121 side flushes, and is convenient to clean and prevents to damage.At this point, drop front 123 and the bottom wall of installation cavity 1211 have
There is certain gap 1231, air inlet 1213 is smoothly sealed for drop front 123.
Optionally, drop front 123 is equipped with the limit convex towards 1211 protrusion of installation cavity close to the side of installation cavity 1211
1233 are played, the outer wall of limit protrusion 1233 is flushed with the side wall of the drop front 123, and limit protrusion 1233 is located at drop front
123 can effectively limit drop front 123 close to the part of itself and the junction of valve body outline border 121 moves in installation cavity 1211
Portion.
Driving device 125 is set to installation cavity 1211, and driving device 125 is connect with drop front 123 for controlling activity
Panel 123 opens or closes air inlet 1213, and specifically, driving device 125 is retractable driving device 125, drop front 123
It is hinged with driving device 125.Since the driving force of driving device 125 is linear drives, pass through drop front 123 and driving device
125 is hinged so that driving device 125 and the angle of the junction of drop front 123 constantly become larger, so that drop front
123 can open or close air inlet 1213.Driving device 125 is electrically connected with the data processor of control host 100.
In the present embodiment, driving device 125 includes box body 126, and motor (not shown) and chain are provided in box body 126
127。
Specifically, chain 127 includes first end (not shown) and second end 1271, and first end is fixed in box body 126,
Second end 1271 drives hinged with drop front 123 for stretching out box body 126 or retraction box body 126, second end 1271 through motor.
Motor is electrically connected with the data processor of control host 100, the motion state of motor is controlled by controlling host 100, and then control
The size of air inlet 1213 processed, and then control the time of pressure release and the size of pressure release.
In order to further increase the precision that driving device 125 controls drop front 123, and then improve the essence of control pressure release
Accuracy, please continue to refer to Fig. 1, box body 126 is fixedly arranged on the bottom wall of installation cavity 1211, and drop front 123 is far from itself and valve body outline border
One end of 121 hinged place is hinged with second end 1271.
During actual use, since the process that chain 127 stretches out box body 126 or is retracted box body 126 will produce centainly
Stress, generate certain loss to it, and then reduce the precision of pressure release, concurrently there are drop front 123 and be directly pulled
To accommodating chamber, the problem of can not effectively sealing air inlet 1213, therefore, the bottom wall of installation cavity 1211, are equipped with limiting plate 128, limit
Position plate 128 is set to side of the box body 126 far from air outlet 1215, and it is separate that 123 selectivity of drop front is resisted against limiting plate 128
The side of box body 126 effectively prevent drop front 123 to be directly pulled in accommodating chamber by the setting of limiting plate 128.Together
When limiting plate 128 and box body 126 interval be arranged, and then box body 126 is stretched out in the part of second end 1271, can be used when stopping
Property under the action of shock limiting plate 128 gently, forming second end 1271 is vibrated, and then discharges stress.And limiting plate
128 with 1233 tight abutment of limit protrusion, effectively improve the accuracy of pressure release.
Wherein, limiting plate 128 can be along the circumferentially disposed of installation cavity 1211, in the present embodiment, and limiting plate 128 is only arranged at
The bottom wall of installation cavity 1211, structure is more simple, while not influencing specifically to use.
In order to ensure air inlet 1213 close when leakproofness, further include be set to limiting plate 128 sealing strip (figure not
Show), sealing strip is located at the junction of limiting plate 128 and drop front 123.Wherein, the length of limiting plate 128 is more than gap 1231
Length, the length of limiting plate 128 herein refers to limiting plate 128 with the junction of 1211 bottom wall of installation cavity to it far from installation
The length of the distance between one end of 1211 bottom wall of chamber, gap 1231 refers to the gap 1231 along the length direction of limiting plate 128
Length.
Optionally, in other embodiments of the invention, driving device 125 is push-rod electric machine, and push-rod electric machine is equipped with telescopic
Push rod (not shown), the one end of drop front 123 far from drop front 123 and the hinged place of valve body outline border 121 and push rod are hinged,
Push-rod electric machine is electrically connected with the data processor of control host 100.
Pressure sensor 110 controls the data processor and pressure sensor of host 100 for acquiring wall pressure at both sides
Pressure of 110 electrical connections for receiving wall both sides, and by calculating, obtain the overbottom pressure value between cup and evacu-ation walk, dredge
The overbottom pressure value between staircase and cup is dissipated, is prevented when fire occurs, smog invades the smoke proof staircase of escape route.
To sum up, the setting of staircase remote-controllable pressure relief device 10 acquires wall pressure at both sides by remote control, leads to
It crosses control host 100 and calculates pressure difference, when pressure difference is unsatisfactory for the requirement of skyscraper smoke control system, such as cup is walked with evacuation
Road overbottom pressure value is more than 30pa, emergency staircase and cup overbottom pressure value and is more than 50pa, carries out pressure release.Simultaneously by controlling host 100
The state of regulation motor, and then opening degree and the folding time of drop front 123 are controlled, effectively carry out pressure release.
It is noted that pressure release is carried out from high pressure to low pressure, therefore, air inlet 1213 is located at the side of high pressure, outlet air
Mouth is located at the side of low pressure, and then effective pressure release, while preventing flue gas from entering high-pressure side from one end of low pressure in pressure leak process.
