Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
As shown in Figure 1 and Figure 2, a kind of gate-valve device for ventilation duct, comprises valve body 1; Be arranged on the flashboard 2 of valve body 1 inside; Flashboard 2 is in rolling curtain type; Be arranged on the actuator 3 of one end in valve body 1; Driving shaft 4 is connected with flashboard 2 one end; By the driven shaft 5 that rope 22 is connected with flashboard 2 the other end; Actuator 3 and driving shaft 4 run through the sidewall of valve body 1 respectively; Driving shaft 4 is connected with actuator 3; Connect the driving mechanism 6 of driving shaft 4 and driven shaft 5; Actuator 3 drives driving shaft 4 clockwise or be rotated counterclockwise pull-up flashboard 2, realizes opening; Actuator 3 drives driving shaft 4 counterclockwise or after turning clockwise and driving driven shaft 5 to rotate by driving mechanism 6, driven shaft 5 pulls flashboard 2 to realize closing by scrolling rope 22.
As shown in Figure 3, Figure 4, the structure size of flashboard 2 and the structure size of valve body 1 inwall suitable.Flashboard 2 is made up of canvas.Many poles 21 are lined with in flashboard 2; Pole 21 be arranged in parallel with driving shaft 4 and driven shaft 5.
As shown in Figure 5, Figure 6, parallel with driving mechanism 6 in valve body 1 two side is respectively equipped with guide rail 11; Ball is provided with in guide rail 11; Pole 21 is slided along guide rail 11 by ball.Driving mechanism 6 is chain; Driving shaft 4 and driven shaft 5 are respectively equipped with gear; Gear on driving shaft 4 and driven shaft 5 is connected with driving mechanism 6 respectively.
Embody rule: flashboard 2 is fixed on inside valve body 1, flashboard 2 then makes rolling curtain type, first many poles 21 are fixed on flashboard 2(canvas) inner side, pole 21 both sides are fixed in guide rail 11 by ball and are not only beneficial to slip, and to flashboard 2(canvas) serve supporting effect, the structure size of flashboard 2 and the structure size of valve body 1 inwall suitable, driving shaft 4 is fixed in side, driven shaft 5 is fixed on by lengthening rope 22 in side, driving mechanism 6(chain is adopted between driving shaft 4 with driven shaft 5) be connected, flashboard 2(canvas), workpiece is all placed in the sealing that ensure that valve inside valve body, double-deck O type circle is adopted to seal between driving shaft 4 and valve body 1, valve is to space environment no requirement (NR).
Due to flashboard 2(canvas) volume/completely inside valve body 1 so spatially can not produce with other equipment and interfere, efficiently solve the sealing of common gate valve and the problem of spatial constraints.Actuator 3 drives driving shaft 4 to turn clockwise pull-up flashboard 2(canvas), valve is opening state; Actuator 3 drives driving shaft 4 to be rotated counterclockwise by driving mechanism 6(chain) drive driven shaft 5 rotate after, driven shaft 5 pulls flashboard 2(canvas by scrolling rope 22) realize close.
