Abstract
The utility model discloses a turning gasket for flange connection, which can resolve the problem such as that in prior art, the direction change of two connected pipes leads high cost. The turning gasket comprises a gasket body; wherein the extension lines of the connecting planes at two sides of the gasket body are crossed to form a corner smaller than 90 degrees. The turning gasket for flange connection, which is provided with a corner, can be used to connect two pipes, with simple change on the connecting direction of the pipes. The turning gasket for flange connection has the advantages of simple structure, low manufacture cost and easy manufacture.
Description
Technical field
The utility model relates to a kind of flange connection packing ring, particularly a kind of turning gasket for connecting flanges.
Background technique
At present, on the pipe or pipeline (pipe) that connect with flange, as shown in Figure 1, packing ring 1 normally is used for sealing the joint of two pipelines, can only change direction with corresponding elbow 2 if want to change direction.And the angle of existing elbow mostly be greatly 90 degree (also can be designed to as required sometimes other angle as: 22.5,45,90 degree), angle is too big, can not satisfy the requirement of " fine setting direction " in the practical operation, as making often difficulty relatively of connection.And for the elbow of some specific (special) requirements (angle of the elbow among Fig. 1 is 11 degree), it is big that it makes difficulty of processing, and versatility is poor.
Connect for the flange of some larger caliber, as concrete agitation station, each big fix after, be difficult to connect when being connected to each other defeated goods pipe between them again, angle is always a little bit poorer.
The model utility content
For overcoming above-mentioned defective, it is a kind of simple in structure that the purpose of this utility model is to provide, easy to use and can finely tune the turning gasket for connecting flanges of direction.
For achieving the above object, turning gasket for connecting flanges of the present utility model comprises a packing ring body, and wherein, the elongation line that described packing ring body both sides connect the plane intersects shape in an angle, and described angle is less than 90 degree.
Preferably, above-mentioned angle is 5-45 degree (saying that " 0-45 degree " is quite a lot of).
Preferably, described packing ring body is made up of clad and laminboard layer, and described clad is coated on the laminboard layer outer surface.
Preferably, described clad is that soft material is made, and described laminboard layer is a hard material.
Preferably, described soft material is a rubber, and described hard material is a metal.
Preferably, described packing ring body week side shaft to being interval with plural through hole.
Adopt said structure, connect two pipelines by the turning gasket for connecting flanges with angle, can change the connecting direction of pipeline comparatively easily, it is simple in structure, and fabricating cost is low, is suitable for processing.

Embodiment
The utility model is further described below in conjunction with drawings and Examples.
To shown in Figure 8, turning gasket for connecting flanges 3 of the present utility model comprises a packing ring body as Fig. 2, and wherein, the elongation line that described packing ring body both sides connect the plane intersects shape in an angle, and described angle is less than 90 degree.This angle has just determined the corner of pipeline.Above-mentioned angle can design as required, can design in the interval of 5-45 degree (saying that " 0-45 degree " is quite a lot of), also a series can be set as required, as being a series etc. every 5 degree or 10 degree, to adapt to different needs.
The material of above-mentioned packing ring body can be for existing various packing rings, as various rubber washers, metal washer etc.For the packing ring of wide-angle, in order to consider its firm intensity, improve further as the utility model, described packing ring body is by clad 31 and laminboard layer 32, and described clad 31 is coated on laminboard layer 32 outer surfaces.Common described clad is that soft material is made, and as rubber, plastics etc., described laminboard layer is a hard material, as various metals, wood, plastics etc.
As this reality novel improvement is further arranged, described packing ring body week side shaft to being provided with plural through hole 5 (also can be groove), as Fig. 3, Fig. 5 and shown in Figure 9.Like this, the connecting bolt of being convenient to connect two piping flanges penetrates with fastening flange and connects with the position of turning gasket between pipeline, as shown in Figure 9, be subjected to displacement with relative two tube contacts faces after preventing the turning gasket for connecting flanges long-term pressurized of turning gasket for connecting flanges that particularly angle is bigger.Then can not consider for the turning gasket for connecting flanges that angle is less.Certainly, when using the bigger turning gasket for connecting flanges of angle, connecting bolt should bend accordingly, to adapt to this distortion, as the connecting bolt among Fig. 9.
In summary, flange connection of the present utility model can be widely used between various pipelines and the various device by the flange connection with the break-in rubber cushion.Product structure is simple, and is easy to use, makes easy processing, and cost is low, safeguards and changes conveniently.
Obviously, those skilled in the art can carry out various changes and not break away from spiritual scope of the present utility model structure of the present utility model.If therefore these changes belong in the utility model claims and the equivalent technologies scope thereof, then the utility model also is intended to contain these changes.
