Abstract
The utility model discloses a center line sealed butterfly valve which comprises a pipe connection ring and a butterfly plate. A first connection tube is arranged on the upper side of the pipe connection ring, a second connection tube is arranged on the lower side of the pipe connection ring, a third connection tube is arranged on the upper side of the butterfly plate, and a fourth connection tube is arranged on the lower side of the butterfly plate. The first connection tube is connected with the third connection tube in a rotary mode, and the second connection tube is connected with the fourth connection tube in the rotary mode. The center line sealed butterfly valve has the advantages that a sealing rubber layer is covered on the inferior surface of the pipe connection ring, the sealing property between the butterfly plate and the pipe connection ring is good, leakage does not easily occur, and the center line sealed butterfly valve is safe to use.
Description
Technical field
The utility model relates to a kind of butterfly valve, more precisely a kind of center line sealed type butterfly valve.
Background technique
The internal surface of the pipeline fastener rings of butterfly valve of the prior art does not arrange the caulking gum layer, and the internal surface of butterfly plate and pipeline fastener rings is difficult for sealing, easily reveals, and uses more dangerous.
The model utility content
The utility model mainly is to solve the existing technical problem of prior art, thereby provides a kind of internal surface of pipeline fastener rings to be covered with the caulking gum layer, and the sealing between butterfly plate and the pipeline fastener rings is better, is difficult for revealing, and uses the center line sealed type butterfly valve of safety.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of center line sealed type butterfly valve, described butterfly valve comprises a pipeline fastener rings and a butterfly plate, the upside of described pipeline fastener rings is provided with one first connecting cylinder, the downside of described pipeline fastener rings is provided with one second connecting cylinder, the upside of described butterfly plate is provided with one the 3rd connecting cylinder, the downside of described butterfly plate is provided with one the 4th connecting cylinder, and described the first connecting cylinder and described the 3rd connecting cylinder are rotationally connected, and described the second connecting cylinder and described the 4th connecting cylinder are rotationally connected.
As the utility model preferred embodiment, described butterfly valve also comprises an adjusting axle, and described adjusting axle is fixedly connected with described the 3rd connecting cylinder, and described adjusting axle and described the first connecting cylinder are rotationally connected.
As the utility model preferred embodiment, the internal surface of described pipeline fastener rings has been covered with the caulking gum layer.
Therefore the advantage of center line sealed type butterfly valve of the present utility model is, the internal surface of pipeline fastener rings is covered with the caulking gum layer, and the sealing between butterfly plate and the pipeline fastener rings is better, is difficult for revealing, and uses safety.
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.
The utility model provides a kind of internal surface of pipeline fastener rings to be covered with the caulking gum layer, and the sealing between butterfly plate and the pipeline fastener rings is better, is difficult for revealing, and uses the center line sealed type butterfly valve of safety.
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of center line sealed type butterfly valve, this butterfly valve comprises a pipeline fastener rings 1 and a butterfly plate 2, the upside of this pipeline fastener rings 1 is provided with one first connecting cylinder 11, the downside of this pipeline fastener rings 1 is provided with one second connecting cylinder 12, and the upside of this butterfly plate 2 is provided with one the 3rd connecting cylinder 21, and the downside of this butterfly plate 2 is provided with one the 4th connecting cylinder 22, this first connecting cylinder 11 is rotationally connected with the 3rd connecting cylinder 21, and this second connecting cylinder 12 is rotationally connected with the 4th connecting cylinder 22.
As shown in Figure 1 and Figure 2, this butterfly valve also comprises an adjusting axle 3, and this adjusting axle 3 is fixedly connected with the 3rd connecting cylinder 21, and this adjusting axle 3 is rotationally connected with this first connecting cylinder 11.
The internal surface of this pipeline fastener rings 1 has been covered with the caulking gum layer.
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.
