Abstract
The utility model relates to a kind of blind flange, comprise circular cover, the inner side end of circular cover is evenly equipped with a circle fastener, the L-shaped structure of described fastener, the long limit of L shape fastener is connected with circular cover, the minor face of L shape fastener is arranged outwardly, forms draw-in groove between the minor face of L shape fastener and circular cover inner side end, and the degree of depth of this draw-in groove is greater than the thickness of the minor face of L shape fastener.Blind flange of the present utility model is by being arranged on the L shape fastener on inner side end, can with the quick clamping of respective slot pipeline, and then can make just blind flange and pipeline tentatively can be fixed spinning between bolt, thus the follow-up bolt that carries out of setter safety is fixed.
Description
Technical field
The utility model relates to a kind of blind flange.
Background technique
Blind flange, also known as blind flange, is mainly used to blocking pipe road junction, traditional blind flange is relatively simple for structure, just on the cover board be provided with a circle bolt connecting hole, bolt is directly connected with pipeline through attachment hole, and this being connected in as installed exists such defect, for some bigbore pipelines, blind flange is also larger, heavier, and dependence two people must be needed to realize installing, and flange is lifted in a personal responsibility, another positions with bolt, inconvenience very.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of blind flange, is convenient to be connected with pipeline.
The utility model solves the technological scheme that its technical problem adopts: a kind of blind flange, comprise circular cover, the inner side end of circular cover is evenly equipped with a circle fastener, the L-shaped structure of described fastener, the long limit of L shape fastener is connected with circular cover, the minor face of L shape fastener is arranged outwardly, forms draw-in groove between the minor face of L shape fastener and circular cover inner side end, and the degree of depth of this draw-in groove is greater than the thickness of the minor face of L shape fastener.
Further, described circular cover is also evenly equipped with a circle bolt connecting hole.
Further, the quantity of described fastener is 4.
The beneficial effects of the utility model are: blind flange of the present utility model is by being arranged on the L shape fastener on inner side end, can with the quick clamping of respective slot pipeline, and then can make just blind flange and pipeline tentatively can be fixed spinning between bolt, thus the follow-up bolt that carries out of setter safety is fixed.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of blind flange;
Fig. 2 be in Fig. 1 A-A to sectional view;
Fig. 3 be with the utility model with the use of piping schematic;
Fig. 4 is the structural drawing that blind flange is connected with pipeline;
Wherein: 1, circular cover, 2, fastener, 3, draw-in groove, 4, bolt connecting hole.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Fig. 1 Fig. 2, a kind of blind flange, comprise circular cover 1, the inner side end of circular cover 1 is evenly equipped with a circle fastener 2, and the quantity of fastener 2 is 4, the L-shaped structure of fastener 2, the long limit of L shape fastener 2 is connected with circular cover 1, the minor face of L shape fastener 2 is arranged outwardly, forms draw-in groove 3 between the minor face of L shape fastener 2 and circular cover 1 inner side end, and the degree of depth of this draw-in groove 3 is greater than the thickness of the minor face of L shape fastener 2.Circular cover 1 is also evenly equipped with a circle bolt connecting hole 4.
As shown in Figure 3 and Figure 4, the pipe end connected joined together has the connecting ring that aperture is less than inner bore of pipeline, the notch that the minor face that this connecting ring has fastener 2 inserts, after buckle inserts, blind flange is connected on pipeline by the limit that turns an angle, and is finally being fixedly connected with pipeline by blind flange by screw-in bolt.
Blind flange of the present utility model is by being arranged on the L shape fastener 2 on inner side end, can with the quick clamping of respective slot pipeline, and then can make just blind flange and pipeline tentatively can be fixed spinning between bolt, thus the follow-up bolt that carries out of setter safety is fixed.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
