Abstract
The utility model relates to a pneumatic butterfly valve, which comprises a valve body and a pneumatic means, wherein the pneumatic means is composed of a cylinder, a handle and a first rotating shaft. The handle is connected to one end of the rotating shaft. The utility model has the advantages of simple structure and long service life.
Description
Technical field
The utility model relates to valve, relates in particular to a kind of Pneumatic butterfly valve.
Background technique
Pneumatic butterfly valve in the prior art all is made of valve body and Pneumatic actuator, the compression by gas in the cylinder in the Pneumatic actuator or discharge the switching of controlling valve plate.The valve plate of this Pneumatic butterfly valve exists easy to wear, the defective that working life is short.
The model utility content
The purpose of this utility model is to overcome defective of the prior art, designs a kind of Pneumatic butterfly valve of simple in structure, long service life.
For achieving the above object, the technical solution of the utility model is to adopt a kind of Pneumatic butterfly valve, and it comprises valve body and Pneumatic actuator, and Pneumatic actuator comprises cylinder, handle and first rotating shaft, and handle is connected with an end of first rotating shaft.
Wherein, valve body also comprises second rotating shaft that is connected with the other end of first rotating shaft.
Wherein, valve inner can be installed valve plate, and valve plate can use high-abrasive material to make.
Wherein, valve plate can be made by 16Mn.
Wherein, valve plate can be connected by high-strength bolt with second rotating shaft.
Wherein, handle can be connected by first bearing pin with cylinder.
Wherein, Pneumatic butterfly valve can also comprise the support that is welded in valve body and be positioned at the cylinder fixing frame of cylinder 3 belows that the cylinder fixing frame can be connected by second bearing pin with support.
Advantage of the present utility model and beneficial effect are: the Pneumatic actuator of this Pneumatic butterfly valve is simple in structure, and valve plate is by high-abrasive material, and for example 16Mn makes, and experiment showed, that the use of this material makes prolong more than one times the working life of this Pneumatic butterfly valve.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
To shown in Figure 4, the concrete technological scheme of implementing of the utility model is as accompanying drawing 1:
A kind of Pneumatic butterfly valve comprises valve body 1 and Pneumatic actuator, and Pneumatic actuator comprises cylinder 3, first rotating shaft 4 and handle 5, and handle 5 is connected with an end of first rotating shaft 4.
In the present embodiment, valve body 1 also comprises second rotating shaft 6 that is connected with the other end of first rotating shaft 4.
In the present embodiment, the valve body 1 inner valve plate 7 of installing, valve plate 7 uses high-abrasive material, and for example 16Mn makes.
In the present embodiment, valve plate 7 is connected by high-strength bolt with second rotating shaft 6.
In the present embodiment, handle 5 is connected by first bearing pin 8 with cylinder 3.
In the present embodiment, this Pneumatic butterfly valve also comprises the support 9 that is welded in valve body 1 and is positioned at the cylinder fixing frame 11 of cylinder 3 belows that cylinder fixing frame 11 is connected by second bearing pin 10 with support 9.Wherein, cylinder fixing frame 11 is used for fixing cylinder 3.
Pneumatic butterfly valve of the present utility model is when work, by regulating the stroke size of cylinder, making cylinder drive handle rotates around first rotating shaft, handle drives the second rotating shaft rotation, and then the drive valve plate rotates, with this purpose that reaches the opening degree of control valve plate, the opening degree of valve plate has determined the flow by gas in the valve body.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
