Description
Affiliated technical field:
The utility model relates to a kind of fire fighting device of growing apart from the emergent smoke evacuation of underway, especially lines up shape and is installed on underway sky top board with equidistant, again the special spacing grid type exhaust smoke valve of underway of selectively unlocking smoke evacuation as required.
background technique:
At present, on subway and tunnel, widely the large fan of application is supporting with air-valve, it is to have valve body, valve block and relevant opening/closing mechanism composition, it is except the difference in size, in shape and structure, most of manufacturers are basic identical, just in the making of valve block, all adopt splayed shape to split closing, the rotating shaft of valve block is arranged in longitudinal centre of valve block, there is Stamping Steel Ribbon on its longitudinal both sides, can crush seal in the time of closure, but at the two ends of valve block, answer valve block to want turn, Stamping Steel Ribbon can only be divided in to the valve body top and bottom of valve block end face, therefore, rotating shaft place of valve block turn cannot seal at all, this manufacture, the more inleakages of valve block are larger.And the exhaust smoke valve of applying on underway, it is not one or two, but tens of and even hundreds of, and what adopt is negative pressure smoke evacuation, if existing air-valve is used as exhaust smoke valve, because inleakage is large, the exhaust smoke valve of selectively unlocking when emergent, to be subject to the impact that other exhaust smoke valves leak out and reduced the smoke discharging effect of the exhaust smoke valve of opening, and cause more loss, can not be applied on underway with air-valve so existing large fan is supporting.
summary of the invention:
Supporting with air-valve in order to overcome existing large fan, due to rotating shaft place of valve block turn, cannot seal, the more inleakages of valve block are larger, when emergent, the exhaust smoke valve of selectively unlocking will be subject to the impact of leaking out of other exhaust smoke valves, and reduced unlatching exhaust smoke valve smoke discharging effect and cause the deficiency of more loss, the utility model provides a kind of underway special spacing grid type exhaust smoke valve, it is good airproof performance not only, and the smoke evacuation requirement that can be applicable to telecontrol selectivity completely and drive valve.
The technical scheme in the invention for solving the technical problem is: flat solid connecting rod base, rocking arm Cuo, connecting rod and the composition of the valve block opening/closing mechanism taking electric actuator as power on the valve block of withholding on the grid of valve body framework and valve block.
Valve body described in this technological scheme, has four jiaos, upper lower outside anti-limit to become the framework of 90 degree, and there is straight gear centre, the intrinsic bearing support that fills valve block in tank bracket left and right and straight gear, and weld respectively by the grid of valve block quantity straight shelves both sides.
Valve block described in this technological scheme, has dough sheet and the tergite of die forming, in dough sheet four limits, is stained with Stamping Steel Ribbon, and after tergite is clamping with dough sheet riveted; Grow an intrinsic page bearing pin, the intrinsic connecting rod base in centre on another long limit of connecting in two ends on limit at one of valve block.
Valve block opening/closing mechanism described in this technological scheme, is the rocking arm place in electric actuator, and the adjustable material that always draws is linked in sequence, drag link, the valve block being connected in the valve block rocker arm bracket on framework with one end opens and closes rocking arm, and has brace, connects respectively valve block and opens and closes the connecting rod base on rocking arm and valve block.
On the grid of valve body framework, by company's page bearing pin at valve block two ends, penetrate in the bearing support in valve body framework and middle straight shelves, the Stamping Steel Ribbon on valve block four limits is withheld on grid, and connecting rod is packed into the connecting rod base on valve block.While installation at the scene, a sky top board that valve body is inlaid in to passage gives and staying in smoke exhaust port, fix the rocker arm bracket on electric actuator and the leg of frame, at the rocking arm place of electric actuator, connect adjustable total railing, the other end drag link that is connected, horizontal bar bar two ends are moving to be connected in the valve block that valve block opens and closes on rocker arm bracket and to open and close rocking arm, and its top has the connecting rod base on brace and valve block coaxially to connect altogether.After this, get final product hand rocking electric final controlling element, proofread the sealing situation of valve block Stamping Steel Ribbon and grid, and regulate the length of adjustable whole tying rod, complete the optimal seal requirement of valve block and grid, reach the object of the telecontrol selectively unlocking smoke evacuation of this valve.
The beneficial effects of the utility model are: good airproof performance, through-flow rate is high, lightweight, opens and closes flexibly, not yielding, easy transportation and installation, the advantage such as cost is low.
