Specific embodiment
Technical scheme is described further below in conjunction with the accompanying drawings.
As shown in Figure 1-2, zero resistance flute check valve of the invention, including valve body 1, the valve body can be by the He of square shell 100
Upper lid 101 positioned at the one end of square shell 100 is constituted, wherein, pore 2 is opened in the centre of upper lid 101, and from the passage 2 to extension
One section of formation external interface 102 is stretched out, lid level indicator 107 can be set as needed on upper lid 101.The present invention is in ventilation
The valve 3 of monolithic is provided with hole 2, the side of valve 3 extends outward one section and retreads to bending, bending part through body wall
Divide the width of upper and lower ends, door-hinge 4 is installed in bending end, as shown in Figure 3-4, because dogleg section upper end width is less than
Lower end, now the center of gravity of valve 3 lean forward, can be fully open in valve body 1 around door-hinge 4, and when valve is fully open, bending
Part is just against at the opening of body wall.Wherein, door-hinge 4 has two kinds of forms, and one kind is bent axle 401, its upper and lower side difference
Fixed using positioner 5, and limited block 402 is set in the bending place of lower end bent axle, meanwhile, magnetic can be formed around in valve
Block 403, is accordingly provided with iron block groove, and placement positioning iron block 404 wherein, as shown in Figure 3-4 on valve interior wall.Here
Positioner 5 can include being fixed on two location-plates 501 of valve outer wall, and location-plate 501 is provided with location hole 502, bent axle
401 two ends are each passed through the location hole 502 on location-plate 501, are then fixed by set screw 503.Another kind is d-axis,
Its upper and lower side is respectively adopted positioner and fixes, and is provided with gravity block at the valve back side contrary with wrap direction, for making valve
Door is completely closed.The extension of above-mentioned valve and door-hinge can be arranged in the case 504 on the outside of valve body, and the case
504 inwall surroundings are opened up and arrange in groove, groove case sealing ring 505.Meanwhile, sealing ring 103 is provided with valve 3, to realize valve
Close contact when door 3 is closed with upper lid 101, it is air tight.In addition, the other end of valve body can arrange movable base plate 108.According to
Needs can be provided with positioning bar 105 and valve body location hole 106 with valve outer wall.
As seen in figs. 5-6, it is provided with firebreak device 6 in the valve body of check-valves of the present invention；Wherein, firebreak device includes one two
The fire prevention depression bar 601 of end bending, fire prevention base 602, the fire prevention fusing base 603 being individually fixed on valve interior wall, the fire prevention
Base 602 is provided with fire prevention stage clip 604, and the one end for depression bar 601 of preventing fires is through the seat on fire prevention stage clip 604 and fire prevention base 602
Ear 605 is flexibly connected, while the one end of stage clip 604 that prevents fires is fixed on fire prevention base 602, the other end is withheld by the tension force of stage clip
Firmly prevent fires depression bar 601, prevent fires depression bar 601 the other end be sheathed on fire prevention fusing base 603 on fuse link 606 in.Work as generation
During fire, when the rising of valve body temperature reaches the fusing point of fuse link 606, fuse link 606 melts disconnection, and fire prevention depression bar 601 loses
The pressure of fuse link 606, under the rebound effect of fire prevention stage clip 604, beats on valve, forces valve closing, blocks air.
The check-valves of the present invention can be used in lowrise layer, if floor is higher, the negative pressure in flue is higher, and valve is opened
Just it is not easy afterwards to close completely, therefore the axial line of valve body is arranged in a certain angle with horizontal line, angle can be according to reality
Need to adjust so that the center of gravity of valve further leans forward, valve is still capable of achieving under its own weight all closures after opening,
As shown in Figure 1.
