Abstract
The utility model discloses an air leakage prevention plugboard valve which comprises a valve body, a support rail connected with the valve body, and a valve plate which is mounted on the support rail and slides along the support rail, wherein a support plate perpendicular to the valve body is mounted at an opening part, used for inserting the valve plate, of the valve body; a hinge is mounted on the support plate, and fixed with one side of sealing rubber; and the other side of the sealing rubber is fixed with a pressure plate. The valve has the benefits that air leakage of an air conduit is reduced; the sealing performance is good, so that the energy consumption of a fan is reduced; the problem of gap blocking with additional sealing cotton is solved; and the operation is more convenient.
Description
Technical field
The utility model relates to a kind of Anti-air-leakage push-pull valve.
Background technique
At present, ventilating engineering adopts the push-pull valve of field fabrication conventionally, this kind of push-pull valve mainly comprises several parts (close improvement or the modification structures such as valve body, valve plate, supporting track, parts are different), be all generally by promoting valve plate to-and-fro motion on supporting track, realize the Kai Heguan of valve.Above-mentioned push-pull valve, due to valve plate and valve body insertion jointing, has certain space, and sealing is poor, causes fan energy consumption waste; In using process, often, after each operation valve plate, additionally employing sealing is cotton carries out plug for seal, inconvenient operation to space.
Summary of the invention
The utility model causes for current space of inserting interface due to valve plate and valve body for the push-pull valve in blower fan that sealing is poor, space is easily stopped up, unhandy problem, has proposed a kind of good airproof performance, easy to operate Anti-air-leakage push-pull valve.
Anti-air-leakage push-pull valve described in the utility model, the supporting track that comprises valve body, be connected with valve body, the valve plate that is installed on supporting track and slides along supporting track, it is characterized in that: described valve body is equipped with the dunnage vertical with valve body for the opening that inserts valve plate, in described dunnage, hinge is installed; The wherein one side of described hinge and stripper rubber is fixing, the another side stationary platen of described stripper rubber.
Described hinge is fixed in described dunnage by thread screw.
Described stripper rubber wherein one side by thread screw and described hinge fix, another side is fixed on pressing plate by rivet.
Described push-pull valve is arranged on the intake grill place of blower fan.
The intake grill place that described push-pull valve is arranged on blower fan, is furnished with latch on described pressing plate.
When use, when needing pull-out or advance valve plate, hinge is opened and driven stripper rubber to separate with valve plate, can, because of the action of frictional influence valve plate, after valve plate has operated, then hinge not closed, stripper rubber and valve plate laminating, realize sealing; If push-pull valve is arranged on the intake grill place of blower fan, in pipeline, carry pressure condition, blast can naturally make stripper rubber and valve plate, valve body compress, and well plays seal action; If be arranged on the exhaust outlet of blower fan, can increase latch fixing seal rubber, avoid sealing surface because blast and valve plate depart from, reduce sealing effect.
The beneficial effects of the utility model are: reduce leaking out of ventilation duct, and favorable sealing property, thus reduce the energy consumption of blower fan; Solve the situation that extra employing seals cotton shutoff space, more convenient to operate.
Brief description of the drawings

Embodiment
Further illustrate the utility model below in conjunction with accompanying drawing
With reference to accompanying drawing:
Anti-air-leakage push-pull valve described in the utility model, the supporting track 2 that comprises valve body 1, be connected with valve body, the valve plate 3 that is installed on supporting track and slides along supporting track, described valve body 1 is equipped with the dunnage vertical with valve body 11 for inserting the opening of valve plate, in described dunnage 11, hinge 12 is installed; Described hinge 12 is fixing with the wherein one side of stripper rubber 13, the another side stationary platen 14 of described stripper rubber 13.
Described hinge 12 is fixed in described dunnage 11 by thread screw.
Described stripper rubber 13 wherein one side by thread screw and described hinge 12 fix, another side is fixed on pressing plate 14 by rivet.
Described push-pull valve is arranged on the intake grill place of blower fan.
Described push-pull valve is arranged on the intake grill place of blower fan, on described pressing plate 14, is furnished with latch.
When use, when needing pull-out or advance valve plate 3, hinge 12 is opened and driven stripper rubber 13 to separate with valve plate 3, can, because frictional influence valve plate 3 moves, after valve plate 3 has operated, then hinge 12 not closed, stripper rubber 13 is fitted with valve plate 3, realizes sealing; If push-pull valve is arranged on the intake grill place of blower fan, in pipeline, carry pressure condition, blast can naturally make stripper rubber 13 and valve plate 3, valve body 1 compress, and well plays seal action; If be arranged on the exhaust outlet of blower fan, can increase latch fixing seal rubber 13, avoid sealing surface because blast and valve plate 3 depart from, reduce sealing effect.
Content described in this specification embodiment is only enumerating of way of realization to model utility design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also comprises that those skilled in the art conceive the equivalent technologies means that can expect according to the utility model.
