Detailed description of the invention
Fig. 1, the structural schematic diagram of the utility model.
Specific embodiment
A kind of improved oil-smoke-exhausting fireproof check valve, including check-valves air door seat 1 offer on check-valves air door seat 1
Several mounting hole 1-1, the centre of check-valves air door seat 1 offer mist extractor stomata 1-2, the edge setting of mist extractor stomata 1-2
There is the hole wall 1-3 vertical with check-valves air door seat 1, is rotatably equipped on check-valves air door seat 1 by shaft 6 and blocks exhausting oil fume
The air door plate 2 of hole 1-2 stamps out on the air door plate 2 to the side mist extractor stomata 1-2 and is sheathed with mist extractor stomata 1-
A circle seal bead 2-1 in 2, the edge of seal bead 2-1 to air door plate 2 is set as connecing with the end face of mist extractor stomata 1-2
One layer of sealing rubber layer is bonded on the sealing surface 2-2 of touching, sealing surface 2-2.
The two sides of the hole wall 1-3 are fixed with one group of support plate 3 in parallel, inclined in support plate 3 to offer sliding slot 4,
Passing through in sliding slot 4 has the compression bar 5 for squeezing air door plate 2, is connected on compression bar 5 by compression bar 5 to the drawing far from the pulling of 6 side of shaft
Spring 7, the both ends of tension spring 7 are connected on the both ends of compression bar 5, and the middle section of tension spring 7 is set on the outside of hole wall 1-3,
The outer end of support plate 3 is fixed with the transverse slat vertical with support plate 3, and the hook that hook holds compression bar 5 is fixed on transverse slat.It is horizontal in Fig. 1
Plate and hook are not shown, reference can be made to " 201721076619.6 " number patent.
The compression bar 5 is arranged in parallel with shaft 6, and the cross section of seal bead 2-1 is at a V-structure.
The end of the hole wall 1-3 is set as one to the inclined inclined-plane in 6 side of shaft, after air door plate 2 is closed, air door
Plate 2 covers on the inclined-plane.
The fusing point of the hook is not more than 150 DEG C.
The outside of the hole wall 1-3 is provided with the convex block 1-4 for preventing 7 landing of tension spring.In figure, tension spring 7 is not sheathed with
On hole wall 1-3, reference can be made to " 201721076619.6 " number patent.
The sliding slot 4 from the edge of check-valves air door seat 1 to centre be gradually obliquely installed, sliding slot 4 far from transverse slat one
The angle that is upturned is held to form a card slot 4-1.
The use of the utility model is same as " 201721076619.6 " number patent.
Under normal use state, 5 hook of compression bar is held on hook, and air door plate 2 can be rotated along shaft 6, i.e., openable row
Oil smoke stomata 1-2 achievees the effect that kitchen ventilator pump drainage cooking fume.
When encountering fire behavior, the intensity of a fire enters the utility model by chimney, and hook encounters the intensity of a fire, and (high temperature is more than 150
DEG C), it links up with and melts rapidly, pulling force of the compression bar 5 by tension spring 7, compression bar 5 is mobile to the side far from shaft 6, and compression bar 5 snaps onto
In card slot 4-1, compression bar 5 is extruded on air door plate 2, and air door plate 2 is not openable, the clogging mist extractor stomata 1-2 of air door plate 2, is risen
It is acted on to fireproof.
After the utility model is improved for air door plate 2, the circle seal bead 2-1 on air door plate 2 is sheathed with exhausting oil fume
In the 1-2 of hole, meanwhile, sealing surface 2-2 is depressed on the end face of mist extractor stomata 1-2, and sealing rubber layer encounters fire behavior, it is melted,
The effect for playing the role of bonding, further realizes sealing.
