Abstract
The utility model discloses a flange type butterfly valve provided with a limiting plate. The butterfly valve comprises a pipeline connecting barrel, an operating handle, a butterfly plate and a rotating shaft, wherein the rotating shaft is connected with the butterfly plate through bolts, the operating handle is connected with the rotating shaft in a mutually perpendicular mode, two ends of the pipeline connecting barrel are respectively provided with a connecting flange ring, and the pipeline connecting barrel is provided with a shaft sleeve which is connected with the rotating shaft in a rotating mode. The flange type butterfly valve provided with the limiting plate has the advantages of being provided with a limiting column and the fan-shaped limiting plate, being capable of being opened and closed quickly and improving a butterfly valve in the prior art conveniently, and being simple in structure.
Description
Technical field
The utility model relates to a kind of butterfly valve, more precisely a kind of flange-type butterfly valve with limiting board.
Background technique
Do not have limiting board on the butterfly valve of the prior art, the user can't judge the residing position of current butterfly plate when regulating butterfly plate, can't open and close fast butterfly valve, uses extremely inconveniently, and closed imprecise situation easily occurs, easily causes fluid leakage.
The model utility content
The utility model mainly is to solve the existing technical problem of prior art, thereby provide a kind of with limited post and fan-shaped limiting board, can open and close fast butterfly valve, simple in structure, the flange-type butterfly valve with limiting board of repacking butterfly valve of the prior art that can be more convenient.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of flange-type butterfly valve with limiting board, described butterfly valve comprises a pipeline connecting cylinder, an operating grip, a butterfly plate and a rotating shaft, described rotating shaft and described butterfly plate are bolted, described operating grip and mutual vertical connection of described rotating shaft, the two ends of described pipeline connecting cylinder are respectively arranged with an adpting flange circle, be provided with an axle sleeve on the described pipeline connecting cylinder, described rotating shaft and described axle sleeve are rotationally connected.
As the utility model preferred embodiment, described pipeline connecting cylinder comprises a fan-shaped limiting board, and described fan-shaped limiting board is fixedly connected with the end of described axle sleeve, is provided with an arc-shaped limit hole on the described fan-shaped limiting board.
As the utility model preferred embodiment, described butterfly valve also comprises a limited post, and described limited post and described operating grip be vertical being fixedly connected with mutually, and the other end of described limited post passes described arc-shaped limit hole and arranges.
Therefore the advantage of the flange-type butterfly valve with limiting board of the present utility model is, with limited post and fan-shaped limiting board, can open and close fast butterfly valve, and is simple in structure, repacking that can be more convenient butterfly valve of the prior art.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
It is a kind of with limited post and fan-shaped limiting board that the utility model provides, and can open and close fast butterfly valve, simple in structure, the flange-type butterfly valve with limiting board of repacking butterfly valve of the prior art that can be more convenient.
As shown in Figure 1 and Figure 2, a kind of flange-type butterfly valve with limiting board, this butterfly valve comprises a pipeline connecting cylinder 1, an operating grip 2, a butterfly plate 3 and a rotating shaft 4, this rotating shaft 4 is bolted with this butterfly plate 3, this operating grip 2 and these 4 mutual vertical connections of rotating shaft, the two ends of this pipeline connecting cylinder 1 are respectively arranged with an adpting flange circle 11, are provided with an axle sleeve 12 on this pipeline connecting cylinder 1, and this rotating shaft 4 is rotationally connected with this axle sleeve 12.
As shown in Figure 3, this pipeline connecting cylinder 1 comprises a fan-shaped limiting board 13, and this fan-shaped limiting board 13 is fixedly connected with the end of this axle sleeve 12, is provided with an arc-shaped limit hole on this fan-shaped limiting board 13.
As shown in Figure 1 and Figure 2, this butterfly valve also comprises a limited post 5, and this limited post 5 and this operating grip 2 be vertical being fixedly connected with mutually, and the other end of this limited post 5 passes this arc-shaped limit hole and arranges.
Below only with a mode of execution mentality of designing of the present utility model is described, in the situation that system allows, the utility model can expand to simultaneously external more function module, thereby expands to greatest extent its function.
The above only be embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
