Abstract
The utility model discloses a large-size gas valve driven by a cylinder. The large-size gas valve comprises a valve body (1), a sealing plate (2), a valve plate (3) and the cylinder. The valve body (1) is fixedly connected with the sealing plate (2), the valve plate (3) is fixedly connected with the valve body (1) or the sealing plate (2), and the valve plate (3) is connected with the cylinder. The large-size gas valve is characterized by artful conception, simple structure, short opening and closing time and tight seal.
Description
Technical field
The utility model belongs to the environmental protection equipment field, relates to a kind of except the large scale valve of nitre with air cylinder driven.
Background technique
According to provisions of laws and regulations such as the Law on Environmental Protection of the People's Republic of China, " The Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution ", the content of sulfur dioxide in the flue gas after various containing sulfur minerals burnings must be removed to below the regulation requirement.
At present, pending flue gas must enter desulphurization system and process, and flue gas needs to be transported to desulphurization system with flue before entering desulphurization system.Along with the maximization of containing sulfur minerals fuel-burning equipment, original bottom flue valve used can not satisfy the requirement after flue maximizes.What use on present large-scale flue is generally the louver damper valve, and there is complex structure in it, and opening/closing time is long, the airtight shortcoming such as not tight.
The model utility content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of and be skillfully constructed, simple in structure, opening/closing time is short, and is airtight tight.
For achieving the above object, the utility model solves the technological scheme that its technical problem adopts and is:
A kind of except nitre with the large scale valve of air cylinder driven, comprise valve body, sealing plate, valve plate and cylinder, described valve body and sealing plate are fixedly connected with, described valve plate and valve body or sealing plate are fixedly connected with, described valve plate is connected with cylinder.
As optimal way, described valve plate and valve body or sealing plate are hinged.
As optimal way, described valve body and valve plate are for being circle or square.
As optimal way, described valve inner is provided with at least one sealing plate.
As optimal way, described sealing plate is ring or square.
As optimal way, the cylinder sleeve of described cylinder is hinged on outside valve body.
As optimal way, piston crown and the valve plate of described cylinder are hinged.
As optimal way, described valve plate is one at least.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
The utility model device is skillfully constructed, simple in structure, by valve body, sealing plate, being used in conjunction with of valve plate, linkage mechanism, driving mechanism, solved the shortcoming of existing large scale gas valve, its device structure is simple, easy to make, failure rate is low, long service life.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Embodiment 1: as Figure 1-3, a kind of large scale valve of using air cylinder driven except nitre comprises valve body 1, sealing plate 2, valve plate 3 and cylinder, and described valve body 1 is fixedly connected with sealing plate 2, described valve plate 3 is fixedly connected with valve body 1 or sealing plate 2, and described valve plate 3 is connected with cylinder.
Described valve body and valve plate are for being circular, and described sealing plate is ring.The cylinder sleeve of described cylinder is hinged on outside valve body, and piston crown and the valve plate of described cylinder are hinged.
Embodiment 2: as Figure 1-3, a kind of valve body 1, sealing plate 2, valve plate 3, cylinder are welded with sealing plate 2 on valve body 1 except the large scale valve of nitre with air cylinder driven, and valve plate 3 is hinged on valve body 1 or sealing plate 2, swings around articulating point under cylinder action.
In use, gas enters valve plate 3 left sides in valve body 1 from valve left side.
When valve closing, gas pressure acts on valve plate 3 left sides, makes valve plate 3 right sides be pressed on sealing plate 2 left sides, and gas can not pass through valve.
When needs are opened valve and are passed through by gas, pressurized air makes cylinder piston rod 7 in the interior motion of cylinder liner 8, the cylinder overall length shortens, by the valve plate activity ship and resell on another market 13, the movable swivel base 4 of valve plate makes valve plate 3, valve plate transfer ear 5, valve plate fixing swing pin 12 around valve plate fixedly swivel base 6 rotate counterclockwise, progressively open valve, allow gas pass through.
When the needs throttle down does not allow air cylinder driven pass through, pressurized air makes cylinder piston 7 in the interior motion of cylinder liner 8, the elongation of cylinder overall length, by the valve plate activity ship and resell on another market 13, the movable swivel base 4 of valve plate makes valve plate 3, valve plate transfer ear 5, valve plate fixing swing pin 12 around valve plate fixedly swivel base 6 clockwise rotate, throttle down progressively is until valve plate 3 right sides are adjacent on sealing plate 2 left sides.
Cylinder integral body is shipped and resell on another market 11 hinged on the first cylinder saddle 9 with cylinder, the first cylinder saddle 9 is welded on the second air cylinder support 10, and the second air cylinder support 10 is welded on valve body 1.In the interior shortening of cylinder liner 8, when extending, cylinder integral body ships and resell on another market 11 around the first cylinder saddle 9 swings by cylinder when cylinder piston 7.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
