Description
Technical field
The utility model belongs to civil air defense constructions and installations protection field, is specifically related to the valve on a kind of explosion-wave-preventing door, relates in particular to a kind of explosion wave prevention active door.
Background technology
In existing technology, what explosion wave prevention active door generally adopted is suspension valve door leaf, when this door leaf is opened and the whole certain angle that forms of doorframe, when being subject to shock wave and impacting, because having impact force that certain angle can make to be subject to decompose, door leaf causes unresponsive phenomenon.The suspension valve door leaf that existing explosion wave prevention active door adopts because do not have a kind of restraint to allow it be close to ventilation opening, leaks so may cause door leaf to contact the radiation not exclusively causing after blast with ventilation opening when enclosed ventilation mouth, and human body is damaged.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the explosion wave prevention active door that a kind of safety factor is high, simple in structure, flat appearance is attractive in appearance is provided.
The purpose of this utility model is to realize like this, a kind of explosion wave prevention active door, comprise fixedly doorframe, in described fixedly doorframe, upper and lower side is provided with support column, described support column top is provided with swivel bearing, swivel bearing is connected with rotary supporting rod, rotary supporting rod is connected and fixed support bar, and the air pressure telescopic link being connected with fixed support bar, described rotary supporting rod is connected by swivel bearing with fixed support bar, described air pressure telescopic link comprise air pressure bracing stick and with the supporting sleeve of air pressure bracing stick, described air pressure telescopic link is connected with push and pull bar push-and-pull place, the other end of described push and pull bar is connected to valve door leaf leeward side, described fixed gate edge is along being provided with sealing joint strip.
Described support column has four, and above and below is respectively provided with two.
Described push and pull bar has two.
Described air pressure telescopic link has four, and two ends, two push and pull bar left and right respectively connect one.
Described valve door leaf leeward side edge is provided with sealing joint strip.
Described valve door leaf windward side scribbles protective paint.
The beneficial effects of the utility model are: adopt drawing valve door leaf, under the state ventilating, door leaf and doorframe do not form angle, and when being subject to shock wave, the stressed homogeneous reaction in the windward side of whole door leaf is sensitiveer.On fixed gate edge edge, be provided with sealing joint strip, and at valve door leaf leeward side edge, sealing joint strip be set, when closure, between sealing joint strip, contact makes sealing effect better.When closure state, air pressure telescopic link inwardly stretches rotary supporting rod completely and fixed gate frame forms angle, makes door leaf be subject to inside power and makes close mouth tightr.In valve door leaf windward side, scribble the corrosion that protective paint can effectively protect valve door leaf to cause after blast.Whole adopt plug-type valve, simple in structure and flat appearance is attractive in appearance.
Accompanying drawing explanation
Fig. 1 is structural representation one of the present utility model.
Fig. 2 is structural representation two of the present utility model.
Fig. 3 is structural representation three of the present utility model.
In figure: 1, fixedly doorframe 2, support column 3, swivel bearing 4, rotary supporting rod 5, fixed support bar 6, air pressure telescopic link 7, air pressure bracing stick 8, sleeve 9, push and pull bar 10, leeward side 11, sealing joint strip 12, windward side 13, valve door leaf 14, rolling bearing.
The specific embodiment
Below in conjunction with embodiment, the technical solution of the utility model is further illustrated:
Embodiment 1
As depicted in figs. 1 and 2, a kind of explosion wave prevention active door, comprise fixedly doorframe 1, the interior upper and lower side of described fixedly doorframe 1 is provided with support column 2, described support column 2 tops are provided with swivel bearing 3, swivel bearing 3 is connected with rotary supporting rod 4, rotary supporting rod 4 is connected and fixed support bar 5, and the air pressure telescopic link 6 being connected with fixed support bar 5, described rotary supporting rod 4 is connected by swivel bearing 14 with fixed support bar 5, described air pressure telescopic link 6 comprise air pressure bracing stick 7 and with the supporting sleeve 8 of air pressure bracing stick, described air pressure telescopic link 6 is connected with push and pull bar 9 push-and-pulls place, the other end of described push and pull bar 9 is connected to valve door leaf leeward side 10, described fixedly doorframe 1 edge is provided with sealing joint strip 11.
During use, promote push and pull bar, the swivel bearing of rotary supporting rod on support column is to outer support, air pressure telescopic link is shunk by extended configuration gradually, continue to promote push and pull bar rotary supporting rod and air pressure bracing stick place in the same horizontal line, again promoting push and pull bar rotary supporting rod outwards rotates, air pressure telescopic link stretches until reach limit positions, forms as the open mode of Fig. 2.When being subject to shock wave, because the stressed contraction rotary supporting rod of the stressed air pressure telescopic link in door leaf windward side inwardly moves and closes ventilation opening, while reaching boundary, air pressure telescopic link is in unfolding state, and the rotary supporting rod inwardly door leaf of integral body is subject to inside closing force.At fixed gate edge along being arranged at the sealing process that plays that sealing joint strip can more have.The utlity model has large, the easy to operate advantage of safety factor.
