Description
Technical field
The present invention relates to a kind of air-valve, be specifically related to a kind of hermetically sealed gate-type opening and closing combination air-valve, its air channel end for large fan, as the switch in air channel, belongs to blower fan accessory technical field.
Background technique
In the prior art, the air-valve of large fan air channel end is substantially assembled on mesh sheet shelving by some butterfly nets and forms.But, in the making of mesh sheet, be the rigidity of reinforcement mesh, need in mesh sheet the stiffening rib that longitudinally compacting angle is different, then involutory for two panels mesh sheet and form whole piece butterfly net.
Meanwhile, be provided with some bearing holes at the both sides Jun Chong of mesh sheet shelving, square internally and round externally copper bearing can be put in bearing hole.One square shaft can pass copper bearing, and is pressed in mesh sheet, makes mesh sheet be that splayed shape is split, to closed type structure.
But, owing to mesh sheet being formed in concaveconvex shape after stiffening rib, although and Stamping Steel Ribbon has the shape same with mesh sheet, because Stamping Steel Ribbon is placed on the positive and negative of the centre that two valve blocks close, most meshing not just, thus cause and leak out.Again because square internally and round externally copper bearing will rotate, be again that Stamping Steel Ribbon disconnects part, therefore, at copper bearing, place cannot seal at all, makes the air-valve inleakage of this form large, is difficult to solve sealing problem, does not reach Its Relevant Technology Standards, can not be used for air channel of smoking.
Therefore, for solving the problems of the technologies described above, the necessary one that provides has structure improved hermetically sealed gate-type opening and closing combination air-valve, to overcome described defect of the prior art.
Summary of the invention
For solving the problem, the object of the present invention is to provide a kind of structure simple, good seal performance, easily manufactured, and the hermetically sealed gate-type opening and closing combination air-valve that can synchronously open or close.
For achieving the above object, the technological scheme that the present invention takes is: a kind of hermetically sealed gate-type opening and closing combination air-valve, and it comprises framework, some sealed doors, Stamping Steel Ribbon, connecting rod, pull bar and electric actuator; Wherein, described framework offers some fixed grating gate hole; The surrounding of each fixed grating gate hole is provided with Stamping Steel Ribbon; Described Stamping Steel Ribbon can be connected to the surface of sealed door; Each sealed door is articulated on framework by a pair hinge, and it is corresponding with a fixed grating gate hole, and can close fixed grating gate hole; Each sealed door is welded with pair of links seat; Each connecting rod base is articulated on connecting rod by a pin; Be positioned on two middle fan sealed doors and be welded with a ram seat respectively; Two ram seat are connected by a link arm; Described pull bar one end is articulated in the central authorities of link arm, and the other end is connected with described electric actuator, and is driven by electric actuator.
Hermetically sealed gate-type opening and closing combination air-valve of the present invention is set to further: described fixed grating gate hole is rectangular arrangement, and is symmetrically distributed in the both sides of pull bar.
Hermetically sealed gate-type opening and closing combination air-valve of the present invention is set to further: the cross section of described Stamping Steel Ribbon is in " 9 " character form structure.
Hermetically sealed gate-type opening and closing combination air-valve of the present invention is set to further: described Stamping Steel Ribbon is fixed on the internal surface of fixed grating gate hole by metal flat bar.
Hermetically sealed gate-type opening and closing combination air-valve of the present invention is set to further: described ram seat is positioned at the neutral position of two connecting rod bases.
Hermetically sealed gate-type opening and closing combination air-valve of the present invention is set to further: described hinge is arranged at one end of sealed door, and described connecting rod base is arranged at the relative the other end of sealed door.
Hermetically sealed gate-type opening and closing combination air-valve of the present invention is also set to: described connecting rod is specially in arranged in parallel 4.
Compared with prior art, the present invention has following beneficial effect: it is simple that hermetically sealed gate-type opening and closing combination air-valve of the present invention has structure, easily manufactured, good airproof performance, and the plurality of advantages such as Stamping Steel Ribbon is not fragile, it can not only synchronously be opened or close, and can realize zero and to leak out requirement, and the air channel being particularly suitable for large fan supports the use.

Embodiment
Refer to shown in Figure of description 1 to accompanying drawing 5, the present invention is a kind of hermetically sealed gate-type opening and closing combination air-valve, and it is made up of a few parts such as framework 1, some sealed doors 2, Stamping Steel Ribbon 3, connecting rod 4, pull bar 5 and electric actuator 6.
Wherein, described framework 1 offers some fixed grating gate hole 7.Described fixed grating gate hole 7 in rectangular arrangement, and is symmetrically distributed in the both sides of pull bar 5.The surrounding of each fixed grating gate hole 7 is provided with described Stamping Steel Ribbon 3.
Described Stamping Steel Ribbon 3 can be connected to the surface of sealed door 2, thus makes laminating between Stamping Steel Ribbon 3 and sealed door 2 tight, and Stamping Steel Ribbon 3 is not fragile.The cross section of described Stamping Steel Ribbon 3 is in " 9 " character form structure, and it is fixed on the internal surface of fixed grating gate hole 7 by metal flat bar 8.
Each sealed door 2 is articulated on framework 1 by a pair hinge 9, and it is corresponding with a fixed grating gate hole 7, and can close fixed grating gate hole 7.Each sealed door 2 is welded with pair of links seat 10.Each connecting rod base 10 is articulated on connecting rod 4 by a pin 11.In the present embodiment, described connecting rod 4 is specially in arranged in parallel 4.Described hinge 9 is arranged at one end of sealed door 2, and described connecting rod base 10 is arranged at the relative the other end of sealed door 2.
Further, be positioned on two middle fan sealed doors 2 and be welded with a ram seat 12 respectively, connected by a link arm 13 between this two ram seat 12.Described ram seat 12 is positioned at the neutral position of two connecting rod bases 10, thus strength required when making promotion balances mutually.
Described pull bar 5 one end is articulated in the central authorities of link arm 13, and the other end is connected with described electric actuator 6, and is driven by electric actuator 6.Because pull bar 5 is positioned at the centre of two row's fixed grating gate hole 7, thus pull bar 5 is firmly economized most, and can not deflect.
The working principle of hermetically sealed gate-type opening and closing combination air-valve of the present invention is as follows: as shown in Figure of description 1, and it is the phase diagram of hermetically sealed gate-type opening and closing combination air-valve of the present invention when closing.When this air-valve needs to open, electric actuator 6 starts, and it pulls pull bar 5, link arm 13, ram seat 12 successively, thus is rotated around hinge 9 by two of centre fan sealed doors 2 and realize opening; Meanwhile, two middle fan sealed doors 2 are drivening rod 4, connecting rod base 10 and drive remaining sealed door 2 rotate around hinge 9 and realize opening successively.
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
