Abstract
The utility model relates to a fire protection system technical field, the especially automatic pressure reliving device of a guard plot outer wall, including the guard plate, one side of guard plate evenly is provided with a plurality of flabellums, the flabellum is opened between two liang has the bleeder vent, guard plate top inboard is provided with the pivot, the pivot is through rotating connecting piece and pressure release board fixed connection, the inside counter weight stick that is provided with of the opposite side that rotates the connecting piece is kept away from to the pressure release board. After the structure of the oil adding device is adopted, the utility model discloses an automatic pressure reliving device's that the other system was used guard plate is in normally closed state, and when atmospheric pressure when the guard plot in was greater than the pressure that can bear, the bleeder vent that the guard plate was passed to fire smothering gas realization boosted the pressure release board to one side to carry out automatic pressure release and need not control and open, saved the energy.
Description
Technical field
The utility model relates to fire prevention system technical field, particularly the automatic decompression device of a kind of guard plot exterior wall.
Background technology
Due to gas extinguishing system there is higher fire-fighting efficiency, lower extinguishing concentration, electrical insulating property are high, clean without performances such as spots, increasing important place employing gas extinguishing system is protected.In order to ensure to put out a fire successfully, gas extinguishing system protection zone requires that in extinguishing chemical dispose procedure guard plot keeps air-tight state, to ensure extinguishing concentration and dip time.In extinguishing chemical dispose procedure, because the seal of guard plot and the rapidity of extinguishing chemical release can cause increasing sharply of guard plot internal pressure, thus cause building enclosure to be destroyed, finally cause putting out a fire unsuccessfully, arrange and cause more serious consequence.
Chinese utility model patent CN202128845U discloses a kind of pressure relief device of gas extinguishing system, comprise casing, at least a slice blade, drive unit and the signal feedback device be arranged in casing, described driving child holds and is being connected with the rotating shaft transmission of described blade, described vane tip is provided with a baffle plate, described signal feedback device, drive unit are electrically connected with outside extinguishment control system, the signal that described signal feedback device has been opened for feeding back a blade to described outside extinguishment control system.
Summary of the invention
The utility model technical issues that need to address provide a kind of automatic decompression device of gas extinguishing system.
For solving above-mentioned technical problem, automatic decompression device of the present utility model, comprises protective plate, and the side of described protective plate is evenly provided with some flabellums, and described flabellum has air-vent between any two; Described protective plate top inner side is provided with rotating shaft, and described rotating shaft is fixedly connected with pressure relief plate by rotating connector, and described pressure relief plate is provided with weighted rod away from the opposite side inside of rotating connector.
Further, described rotating connector is right-angle connector, and one end of described right-angle connector is fixedly connected with rotating shaft, and the other end is fixedly connected with pressure relief plate.
Further, described pressure relief plate is fixed with elastic buffering pad near the inner side of protective plate.
Further, affiliated weighted rod is zinc-plated weighted rod.
After adopting said structure, the protective plate of the automatic decompression device of other system of the present utility model is in normally off, when the air pressure in guard plot is greater than the pressure that can carry, pressure relief plate boosts to side by the air-vent that fire smothering gas is known from experience through protective plate, thus carry out releasing pressure automatically and do not need control to open, save the energy.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 a is the structural representation that the pressure relief plate of the utility model automatic decompression device is closed.
Fig. 1 b is the structural representation that the pressure relief plate of the utility model automatic decompression device is opened.
Fig. 2 is the panel construction schematic diagram of the utility model protective plate.
In figure: 1 is protective plate, 2 is rotating shaft, and 3 is right-angle connector, and 4 is pressure relief plate, and 5 is elastic buffering pad, and 6 is weighted rod, and 101 is flabellum, and 102 is air-vent
Detailed description of the invention
As shown in Fig. 1 a and Fig. 2, the automatic decompression device of automatic decompression device of the present utility model, comprise protective plate 1, in order to the gas in guard plot can be discharged from protective plate 1, the side of described protective plate 1 is evenly provided with some flabellums 101, described flabellum 101 has air-vent 102 between any two, and the gas 1 in such guard plot can flow out through air-vent 102.Described protective plate 1 top inner side is provided with rotating shaft 2, and described rotating shaft 1 is fixedly connected with pressure relief plate 4 by rotating connector, and described pressure relief plate 4 is provided with weighted rod 6 away from the opposite side inside of rotating connector.In present embodiment, affiliated weighted rod is zinc-plated weighted rod, and the permission pressure that the weight of described weighted rod sets according to protection zone is determined.
Further, described rotating connector is right-angle connector 3, and one end of described right-angle connector 3 is fixedly connected with rotating shaft 2, and the other end is fixedly connected with pressure relief plate 4.
Further, falling protective plate 1 to make pressure relief plate 4 is effective buffering, and described pressure relief plate 4 is fixed with elastic buffering pad 5 near the inner side of protective plate 1.
Operation principle of the present utility model is as follows: as shown in Figure 1a, and this pressure relief device is arranged on protection zone exterior wall, is in normally off at ordinary times.When guard plot breaking out of fire; before gas extinguishing system release fire-suppressant gas; in order to ensure drug concentration; dip time; ensure to put out a fire successfully; all automatic ventilation equipment in protection zone are in sealing state by automatically closing, and fire extinguishing system release fire-suppressant gas, causes Pressure Drop in protection zone to exceed rapidly the permission pressure of architectural design.As shown in Figure 1 b; when the pressure in protection zone exceedes setting pressure; when in present embodiment being 1.2KPa; due to the effect of pressure; pressure relief plate 4 boosts to side through the air-vent 102 of protective plate 1 by fire-suppressant gas; such pressure relief plate 4 opens the over-pressure gas in rear automatic leakage releasing guard plot, and the building of protection guard plot, reaches extinguishment requirement.
Certainly, weighted rod of the present utility model also can adopt other materials be suitable for, and air-vent also can adopt other shapes be suitable for, and such conversion all drops within protection domain of the present utility model.
Although the foregoing describe detailed description of the invention of the present utility model; but those skilled in the art are to be understood that; these only illustrate; various changes or modifications can be made to present embodiment; and not deviating from principle of the present utility model and essence, protection domain of the present utility model is only defined by the appended claims.
