Description
Technical field
The present invention relates to a kind of air-valve, be specifically related to a kind of hermetically sealed gate-type and open and close the combination air-valve, it is used for the air channel end of 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 assembled on the net sheet group frame by some butterfly nets basically and forms.But, in the making of net sheet, be the rigidity of strengthening net sheet, need on the net sheet, vertically suppress the different stiffening rib of angle, involutory and form whole piece butterfly net two net sheets again.
Simultaneously, be provided with some bearing holes at the both sides Jun Chong of net sheet group frame, in bearing hole, can put into square internally and round externally copper bearing.One square shaft can pass the copper bearing, and is pressed in the net sheet, make the net sheet be splayed shape split, to closed type structure.
But, owing to be concaveconvex shape after forming stiffening rib on the net sheet, though and Stamping Steel Ribbon has the shape same with the net sheet, because Stamping Steel Ribbon is placed on the positive and negative of the centre of two valve block closures, most meshing not just, leak out thereby cause.Because square internally and round externally copper bearing will rotate, be again that Stamping Steel Ribbon disconnects part again, therefore, the place can't seal at all at the copper bearing, makes the air-valve inleakage of this form big, is difficult to solve sealing problem, does not reach the correlation technique standard, can not be used for the smoking air channel.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of and have structure improved hermetically sealed gate-type and open and close the combination air-valve, to overcome described defective of the prior art.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of simple in structure, good seal performance, easily manufactured, and the hermetically sealed gate-type that can open synchronously or close opens and closes the combination air-valve.
For achieving the above object, the technological scheme that the present invention takes is: a kind of hermetically sealed gate-type opens and closes the combination air-valve, and it comprises framework, some sealed doors, Stamping Steel Ribbon, connecting rod, pull bar and electric actuator; Wherein, offer some stationary grizzlies hole on the described framework; Stamping Steel Ribbon is installed around each stationary grizzly hole; Described Stamping Steel Ribbon can be connected to the surface of sealed door; Each sealed door is articulated on the framework by a pair of hinge, and it is corresponding with a stationary grizzly hole, and can seal the stationary grizzly hole; Be welded with the pair of links seat on each sealed door; Each connecting rod base is articulated on the connecting rod by a pin; Be welded with a ram seat respectively on the two fan sealed doors in the middle of being positioned at; Two ram seat connect 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 of the present invention opens and closes the combination air-valve and further is set to: described stationary grizzly hole is rectangular arranges, and is symmetrically distributed in the both sides of pull bar.
Hermetically sealed gate-type of the present invention opens and closes the combination air-valve and further is set to: the cross section of described Stamping Steel Ribbon is " 9 " font structure.
Hermetically sealed gate-type of the present invention opens and closes the combination air-valve and further is set to: described Stamping Steel Ribbon is fixed in the internal surface in stationary grizzly hole by the metal flat bar.
Hermetically sealed gate-type of the present invention opens and closes the combination air-valve and further is set to: described ram seat is positioned at the neutral position of two connecting rod bases.
Hermetically sealed gate-type of the present invention opens and closes the combination air-valve and further is set to: described hinge is arranged at an end of sealed door, and described connecting rod base is arranged at the relative the other end of sealed door.
Hermetically sealed gate-type of the present invention opens and closes the combination air-valve and also is set to: described connecting rod is specially and is 4 that are arranged in parallel.
Compared with prior art, the present invention has following beneficial effect: hermetically sealed gate-type of the present invention opens and closes the combination air-valve and has simple in structure, easily manufactured, good airproof performance, and plurality of advantages such as Stamping Steel Ribbon is not fragile, it can not only be opened or close synchronously, and can realize zero requirement of leaking out, and is particularly suitable for supporting use on the air channel of large fan.

Embodiment
See also Figure of description 1 to shown in the accompanying drawing 5, the present invention is that a kind of hermetically sealed gate-type opens and closes the combination air-valve, and it is made up of several parts such as framework 1, some sealed doors 2, Stamping Steel Ribbon 3, connecting rod 4, pull bar 5 and electric actuator 6.
Wherein, offer some stationary grizzlies hole 7 on the described framework 1.Described stationary grizzly hole 7 is rectangular arranges, and is symmetrically distributed in the both sides of pull bar 5.Described Stamping Steel Ribbon 3 is installed around each stationary grizzly hole 7.
Described Stamping Steel Ribbon 3 can be connected to the surface of sealed door 2, fit closely thereby make between Stamping Steel Ribbon 3 and the sealed door 2, and Stamping Steel Ribbon 3 is not fragile.The cross section of described Stamping Steel Ribbon 3 is " 9 " font structure, and it is fixed in the internal surface in stationary grizzly hole 7 by metal flat bar 8.
Each sealed door 2 is articulated on the framework 1 by a pair of hinge 9, and it is corresponding with a stationary grizzly hole 7, and can seal stationary grizzly hole 7.Be welded with pair of links seat 10 on each sealed door 2.Each connecting rod base 10 is articulated on the connecting rod 4 by a pin 11.In the present embodiment, described connecting rod 4 is specially and is 4 that are arranged in parallel.Described hinge 9 is arranged at an 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 welded with a ram seat 12 respectively on the two fan sealed doors 2 in the middle of being positioned at, connect 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, thereby makes the mutual balance of strength required when promoting.
Described pull bar 5 one ends are articulated in the central authorities of link arm 13, and the other end is connected with described electric actuator 6, and are driven by electric actuator 6.Because pull bar 5 is positioned at the centre in two row's stationary grizzly holes 7, thereby pull bar 5 is firmly economized most, and can deflection.
The working principle that hermetically sealed gate-type of the present invention opens and closes the combination air-valve is as follows: shown in Figure of description 1, it opens and closes the phase diagram of combination air-valve when closing for hermetically sealed gate-type of the present invention.When this air-valve need be opened, electric actuator 6 started, and it spurs pull bar 5, link arm 13, ram seat 12 successively, thereby two fan sealed doors 2 of centre are rotated and realize opening around hinge 9; Meanwhile, middle two fan sealed doors 2 drivening rod 4, connecting rod base 10 and drive remaining sealed door 2 and rotate and realize opening around hinge 9 successively.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
