Description
Technical field
The utility model relates to the safety engineering field, specifically is a kind of anti-fire smoke expelling valve.
Background technique
At present, high-rise all is equipped with ventilation duct, is provided with anti-fire smoke expelling valve in the ventilation duct.Anti-fire smoke expelling valve comprises valve body and is fixed on the actuator of valve body outer (generally being fixed on the valve body top), is provided with valve block in the passage of valve body, is fixed with main shaft on the valve block, and main shaft stretches out outside the valve body and with actuator and is connected.Actuator is by rotating spindle, thereby the band moving valve plate rotates, and then realizes the switching of whole valve body, during such as the transverse cross-section parallel of the passage in valve block and the valve body, valve block blocks passage, and valve body is closed, when the cross section of the passage in valve block and the valve body was vertical, the aperture of whole valve body was maximum.
Because the actuator of the anti-fire smoke expelling valve of prior art is installed in outside the fire and smoke exhaust valve body, like this, the versatility of this anti-fire smoke expelling valve is poor, narrow application range, be only suitable for being installed in the ventilation duct in the space that reserves accommodating actuator, then can't directly install in a lot of ventilation ducts that do not reserve containing space, must break air duct wall and dig out the space of accommodating actuator, again actuator and valve body are installed, so installation process quite bothers, just can't further dig the space of accommodating actuator after some ventilation duct construction is finished still more, can't install at all, and even if be reserved with the space, the process that actuator is packed into headspace and valve body is installed to pipeline is trouble very also.
Summary of the invention
The technical problems to be solved in the utility model is, provide highly versatile, applied widely, simply and easily a kind of anti-fire smoke expelling valve is installed.
Technical solution of the present utility model is, a kind of anti-fire smoke expelling valve is provided, it comprises valve body, be provided with valve block in the passage of valve body, valve block rotatably cooperates with valve body through main shaft, the transverse cross-section parallel that it also comprises drag-line, be used for making valve block and passage is with the resetting means of the passage of closing, drag-line comprises the low melting alloy section, one end of drag-line is connected with the wall of the passage of valve body, the other end of drag-line is connected with valve block, and is vertical with the cross section of the passage of valve body at the acting in conjunction lower valve of drag-line and resetting means.
The working principle of this anti-fire smoke expelling valve is: under normal state, valve block cross section with the passage of valve body under the acting in conjunction of resetting means and drag-line is vertical, the acting in conjunction of resetting means and drag-line refers to elastic force that drag-line overcomes resetting means as extension spring is pulled open, and the aperture of whole valve body is maximum this moment; When the condition of a fire occurs, temperature excursion in the room, the low melting alloy section of drag-line is fused, so that drag-line is to the draw disappearance of valve block, the valve block rotation that only under the effect (retraction such as extension spring is drawn over to one's side) of resetting means, resets, until valve block turns to the transverse cross-section parallel with the passage of valve body, valve block blocks passage, valve body is closed, prevents that flare from channeling to other zones of building through ventilation duct.
Adopt a kind of anti-fire smoke expelling valve of above structure compared with prior art, have the following advantages:
Because the actuator of this anti-fire smoke expelling valve is that drag-line and resetting means all are the passages that are positioned at valve body, like this, the overall volume of this valve body is dwindled, and has omitted the volume of the outer actuator of valve body, so when assembling, no longer need to reserve specially the space of accommodating actuator, more need not to dig out at the conduit wall that does not have in advance headspace the space of accommodating actuator, so the highly versatile of this anti-fire smoke expelling valve, applicability is good, applied widely, install simple and convenient.
As improvement, main shaft and valve block are fixed, and main shaft and valve body are hinged, and such Standard is convenient.
As improving, resetting means is an extension spring again, and extension spring one end is connected with the wall of the passage of valve body, the extension spring the other end is connected with valve block, the transverse cross-section parallel of the passage of extension spring nature lower valve and valve body, such is simple and reliable for structure, and it is all convenient to make, assemble.
As further improvement, drag-line is made of the wire rope at two ends and the fuse sheet of the low melting alloy material of centre, steel cable, fuse link and the root wire rope of being connected connect from beginning to end, like this simple in structure, easily manufactured, tensioning function to valve block under the normal temperature is reliable, and fuse function is also stable automatically under the high temperature.
As also further improving, one end of drag-line is provided with hook, be welded with connecting ring on the valve block, be hooked in the connecting ring, like this, during installation, firmly make valve block overcome the resetting means effect and turn to the state vertical with the cross section of the passage of valve body, then catch on connecting ring on the valve block with the hook of drag-line, just can very easily valve block be seated.
As further improving again, be fixed with link on the wall of the passage of valve body, also be fixed with link on the valve block, the two ends of extension spring are hooked on respectively on two links, and like this, the assembly process of extension spring is convenient and simple.
As preferably, link on connecting ring and the valve block all is positioned on same of valve block, and the both sides of the main shaft of link and connecting ring separation valve block, and such is simple in structure, easy to assembly, and can guarantee at the acting in conjunction lower valve of extension spring and drag-line vertical with the cross section of the passage of valve body.
