Abstract
The utility model relates to an adjusting air valve for opening or closing an exhaust flaring of a metro tunnel, in particular to a curtain type adjusting air valve which can effectively prevent smoke leakage in case of a fire disaster in the tunnel. The curtain type adjusting air valve comprises a frame and a rolling drum which is provided with a curtain, wherein the two ends of the rolling drum are fixed at the upper end of the frame through bearing seats; the bottom end of the frame is provided with a guide wheel bearing pedestal; a curtain guide shaft is arranged below the frame and is provided with a curtain guide wheel and a guide bearing seat; the guide bearing seat is matched with a guide wheel bearing pedestal; the curtain guide wheel is matched with a pulling strap which is connected with the curtain; and a transmission shaft with a speed reducer and a motor is arranged on the same side of the rolling drum and the curtain guide shaft. Through the adjusting air valve, the area of an air outlet can be increased during ventilation, the air leakage rate is small when the adjusting air valve is closed, the smoke leakage can be effectively controlled, personnel are timely evacuated, and the loss of life and property is reduced.
Description
Technical field
The utility model can prevent the curtain type adjusting air-valve of smoke spillage effectively when relating to breaking out of fire in adjusting air-valve, the especially tunnel that a kind of subway tunnel opens and closes the air draft enlarging.
Background technique
At present, air-valve is regulated in smoke evacuation used in the subway tunnel, the adjusting air-valve that generally uses how electric dish formula to split, it is attached together together by tens of vane group forms, and there is the array assembly unit synthetic, this air-valve air intake/outtake surface is long-pending little, component are many, assembling requires superior, has carelessness just to cause poor sealing slightly, leaks out in a large number, air-valve cuts out during breaking out of fire in the tunnel, because blade quantity is many, can not play due smog seal action, and the loss of life and property that causes smog to leak outside and brought in a large number.
Summary of the invention
Many in order to overcome existing air-valve blade quantity, sealability is bad, inleakage is big, the deficiency that causes smog to leak outside in a large number when fire, the utility model provide a kind of curtain type to regulate air-valve, and it can not only increase the exhaust outlet area when ventilating, inleakage is little when closing, can control smog effectively and leak, personnel are in time withdrawn, reduce loss of life and property.
The technical scheme in the invention for solving the technical problem is: a kind of curtain type is regulated air-valve, comprise framework, rolling up of curtain is installed puts cylinder, can roll up the two ends of putting cylinder and be fixed on the framework upper end by bearing support, the bottom of framework is equipped with upper saw pulley bearing base, the below of framework is provided with the curtain axis of guide, the curtain upper saw pulley is installed on the curtain axis of guide, guide bearing chock, guide bearing chock matches with upper saw pulley bearing base, cooperate on the curtain upper saw pulley puller strap that is connected with curtain is installed, can roll up and put cylinder, the homonymy of the curtain axis of guide is equipped with the band speed reducer, drive axle of motor.
As the further setting of such scheme, described framework comprises the external frame of bottom frame, die forming of channel-section steel combination and curtain guiding skeleton, with the stiffening rib that band steel is made, and punching connects to form an integral body; Periphery dress at the both sides of curtain external frame is used Stamping Steel Ribbon, and is connected and fixed with external frame.
The described curtain axis of guide, on the speed reducer of its end face manual system is installed, manual system comprises the manual components support that is connected with speed reducer, small gear, spring seat, spring and hand wheel shaft assembling, put into guide sleeve, locating stud, setting sleeve and electric machine support punching and be connected the handwheel of packing into, handle.
The both ends of the surface that the utility model is opened and closed at air-valve have increased main shaft respectively, upper saw pulley, be connected with puller strap with curtain, make valve become totally-enclosed normality, another termination at the main shaft and the axis of guide, be provided with the fast machine of examination, motor, the direction joint, coupling, transmission shaft, starting electrical machinery, pass through transmission shaft, speed reducer drives main shaft and the axis of guide rotates the opening and closing that realize valve, end face at speed reducer has been set up manual components, can be with manually coming the opening and closing valve when having a power failure, be provided with Stamping Steel Ribbon at the periphery of curtain, valve opening and close and adopt the infrared ray electric control, the infrared rays photoelectricity valve of cutting off the electricity supply automatically becomes to close normality when the curtain standard-sized sheet.Be provided with flue gas transmission rod signaling system in the tunnel, breaking out of fire in the tunnel is when flue gas reaches certain concentration, the tobacco rod telltale feeds back to valve master control cabinet, valve is closed automatically, and another advantage of valve is that curtain can become half-open half off status, but the size of free adjustment air quantity.The material of institute's adapted all can use 2 hours under 280 degree high temperature, controlled smog effectively and leaked the purpose that smog does not leak as far as possible.
The utility model beneficial effect is: can control smog effectively and leak, simple in structure, drop into few, can overall application in the fire-fighting of various subway tunnels, the smoke evacuation effect of taking precautions against natural calamities, ventilating.
