Description
Technical field
The utility model relates to air channel switching construction technical field, and particularly a kind of wind direction changes duct device.
Background technique
What traditional air channel switching valve was conventional has two forms: one, adopt driving stepper motor, soft rubber or the sealing of rubber and plastic heat-preservation cotton.Air channel is all sheet metal part, and size is comparatively large, and machining accuracy is generally not high, although soft rubber and rubber and plastic heat-preservation cotton can be compressed, if the moment of torsion of the large required stepper motor of size is also large, if will close the tight stepper motor must selecting high pulling torque when switching air channel.Because the restriction of installing space, product weight and cost of production can not select the stepper motor of high pulling torque in the middle of practical application, can leak gas during this type of air channel switching valve application body, switches not exclusively.
Another kind of form is that stepper motor or reducing motor drive, and running shaft is on the axle center of wind channel tube.Owing to will leave gap between spool and ventilation duct, can not realize complete switching, can leak gas body equally.
Model utility content
For solving above-mentioned prior art Problems existing, the purpose of this utility model is to provide a kind of wind direction to change duct device.Have deft design, flexible structure is reliable, and sealing is superior, and can not leak gas body, is convenient to dismounting, low cost and other advantages.
For achieving the above object, the technical solution of the utility model is:
A kind of wind direction changes duct device, comprise the hollow connecting plate being fixed on two air intake road junctions, each connecting plate is vertical with its fixing air inlet duct, two connecting plate jointing place up-and-down boundaries are outward extended with the mounting plate of its handing-over axis vertical, mounting plate is fixed with motor, the switching valve side projection that the transmission shaft extended by motor runs through between upper and lower two mounting plates and two mounting plates is connected, projection and transmission shaft geo-stationary, switching valve center is the circular boop type spool of shutoff, in the spool periphery of switching valve, also be fixed with two metal sheets, switching valve rotates to when being close to an air inlet duct position, one tinsel correspondence contacts with a proximity switch, switching valve rotates to when being close to another air inlet duct position, another tinsel contacts another proximity switch.
Further, described connecting plate and switching valve contacting side, be provided with sealing gasket.
Further, described switching valve spool and two side connecting plate surface of contact are provided with seal ring.
Further, described seal ring adopts hollow sealing strip.
Further, the outer tinsel of described spool and projection are all welded and fixed with it or integrally casting.
Further, described motor is fixed by the screw of surrounding and mounting plate.
Relative to prior art, the beneficial effects of the utility model are:
This structure drives with deceleration self-locking motor, and proximity switch is spacing, by the hollow sealing adhesive tape sealing of welding after extrusion molding.Adopt the hollow sealing adhesive tape of extrusion molding welding to carry out sealing contact surface, the wall thickness of adhesive tape is 0.4-0.5mm, is increased in the cross section of adhesive tape especially to increase decrement.The object of this adhesive tape is selected to be reduce the moment of torsion of reducing motor, even if adopt the deceleration self-locking motor of small volume, little moment of torsion, low cost also can realize the function switched.The utility model device reaction is sensitive, reliable and stable, and repetitive positioning accuracy is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Structural representation when Fig. 2 is the utility model device switching air channel.
Wherein, 1-air inlet duct, 2-connecting plate, 3-mounting plate, 4-motor, 5-transmission shaft, 6-projection, 7-spool, 8-tinsel, 9-proximity switch, 10-sealing gasket, 11-seal ring.
Embodiment
Below in conjunction with the drawings and the specific embodiments, technical solutions of the utility model are described in further detail:
As shown in Figure 1, a kind of wind direction changes duct device, comprise the hollow connecting plate 2 being fixed on two air inlet ducts 1 mouthful, each connecting plate 2 is vertical with its fixing air inlet duct 1, two connecting plate 2 jointing place up-and-down boundaries are outward extended with the mounting plate 3 of its handing-over axis vertical, mounting plate 3 is fixed with motor 4, the switching valve side projection 6 that the transmission shaft 5 extended by motor 4 runs through between upper and lower two mounting plates 3 and two mounting plates 3 is connected, projection 6 and transmission shaft 5 geo-stationary, switching valve center is the circular boop type spool 7 of shutoff, in spool 7 periphery of switching valve, also be fixed with two metal sheets 8, switching valve rotates to when being close to air inlet duct 1 position, one tinsel 8 correspondence contacts with a proximity switch 9, switching valve rotates to when being close to another air inlet duct 1 position, another tinsel 8 contacts another proximity switch 9.
Further, described connecting plate 2 and switching valve contacting side, be provided with sealing gasket 10.
Further, described switching valve spool 7 and two side connecting plate 2 surface of contact are provided with seal ring 11.
Further, described seal ring 11 adopts hollow sealing strip.
Further, the outer tinsel 8 of described spool 7 is all welded and fixed with it or integrally casting with projection 6.
Further, described motor 4 is fixing with mounting plate 3 by the screw of surrounding.
Working principle of the present utility model is: as shown in Figure 2, and in real work, gas enters from an air inlet duct 1, and another air inlet duct 1 is close to by switching valve, is closed by this air inlet duct 1 by the seal ring 11 of spool 7 and sealing gasket 10 and correspondence.When needing to switch air inlet duct 1, motor 4 operates and drives projection 6 and spool 7 to rotate by transmission shaft 5, until the tinsel 8 on spool 7 touches the proximity switch 9 on another air inlet duct 1 connecting plate 2, motor 4 shuts down, and vice versa.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
