Abstract
The utility model discloses a threaded flange which comprises a plate body, wherein a plurality of evenly distributed through holes are arranged on the plate body, an annular dummy club is arranged in the centers of the top surface and the bottom surface of the plate body respectively, the inner diameters of the two annular dummy clubs are equal, a threaded hole is formed and penetrates through the center of the plate body, and a thread is arranged on the inner side wall of the threaded hole; and a bevel is arranged at the intersection of the top and bottom surfaces of the plate body and the side wall, and the bevel is arranged at the intersection of the inner wall of the through hole and the top and bottom surfaces of the plate body. An outer bevel is arranged at the intersection of the top and bottom surfaces of the plate body and the side wall, and the outer bevel is arranged at the intersection of the inner wall of the through hole and the top and bottom surfaces of the plate body, so that the edges of the plate body and through hole are prevented from being impacted to form a gap when a shaft or a bolt is installed, thereby improving the processing effect.
Description
Technical field
The utility model relates to a kind of flange, relates in particular to a kind of be used to the connect relative axle or the screwed flange of pipe.
Background technique
Flange is flange plate or bead again.Flange is to make pipe and the interconnective part of pipe, is connected in pipe end.Perforation on the flange utilizes bolt that two flanges are closely connected, and seals with liner between flange.Flange comprises screwed flange and welded flange.Wherein, screwed flange is applicable to fire-fighting, coal gas, hot and cold water, air-pressure tube, oil pipe, industry such as hydraulic tube and the sealing of commercial tubes thread locking etc.
Existing screwed flange comprises the flange disk body, disk body is provided with tapped hole and through hole, general traditional screwed flange is not to the seamed edge of disk body, it is the jointing place of end face and the bottom surface and the sidewall of disk body, carry out any processing, the screwed flange of making is dropped in, cause reeling of disk body edge easily when using and cause breach.Same, the screwed flange of prior art does not carry out any processing to the end face of through hole madial wall and disk body and the jointing place of bottom surface, when axle or bolt pass through hole and install, damages the seamed edge of through hole and disk body jointing place easily, causes breach, influences use.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of installation simple, does not allow flimsy screwed flange.
Scheme of the present utility model: a kind of screwed flange, comprise disk body, described disk body is provided with some equally distributed through holes, the end face of disk body and the middle part of bottom surface are respectively equipped with an annular boss, the interior ring diameter of two annular boss is identical, form a tapped hole at the middle part of disk body, tapped hole runs through the middle part of disk body, and the madial wall of tapped hole is provided with screw thread; The intersection of the end face of described disk body and bottom surface and sidewall is provided with groove, and the intersection of the inwall of described through hole and the end face of disk body and bottom surface is provided with groove.
Preferably, be provided with several equally distributed through holes around the described disk body, the center of circle of through hole is distributed on the same circle.After adopting above-mentioned preferred scheme, the position distribution of through hole is even, and the center of circle of through hole preferably is arranged on the same circle, and fixed effect is better, has improved the utilization efficiency of equipment.
Preferably, the angle of the inclined-plane of described outer groove and the end face of disk body and bottom surface is 25 °～70 °, and the angle of the inclined-plane of described internal groove and the end face of disk body and bottom surface is 25 °～70 °.After adopting above-mentioned preferred scheme, internal groove and the angle with end face disk body and bottom surface outer groove preferably are provided with, other component are to the destruction at the edge of disk body and through hole when reducing installation.
Preferably, the internal diameter of described tapped hole is 20～168mm, adopt above-mentioned preferred scheme after, the internal diameter in double thread hole preferably is provided with, better effects if when screwed flange is cooperated with pipeline.
Preferably, the aperture of described through hole is 16～22 mm, adopt above-mentioned preferred scheme after, the aperture of through hole preferably is provided with better effects if when screwed flange is cooperated with pipeline.
Screwed flange of the present utility model is groove outside the jointing place of the end face of disk body and bottom surface and sidewall is provided with, at the end face of through-hole wall and disk body and the intersection of bottom surface internal groove is set, avoid when installation shaft or bolt edge to disk body and through hole to cause reeling and formed breach, improved processing effect.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the utility model embodiment's a side structure schematic representation.
Embodiment
As depicted in figs. 1 and 2, a kind of screwed flange comprises disk body 1, and disk body 1 is provided with 4 equally distributed through holes 3, and the center of circle of through hole 3 is distributed on the same circle.Through hole 3 is used for the fixedly connected of axle or bolt.The interior ring diameter that the end face of disk body 1 and the middle part of bottom surface are respectively equipped with 12, two annular boss 12 of an annular boss is identical, forms a tapped hole 2 at the middle part of disk body 1, and tapped hole 2 runs through the middle part of disk body 1, and the madial wall of tapped hole 2 is provided with screw thread 21; The intersection of the end face of disk body 1 and bottom surface and sidewall is provided with the outer groove 11 into the annular slope shape, and the end face of the inwall of through hole 3 and disk body 1 and the intersection of bottom surface are made as the internal groove 31 of annular slope shape.Avoid when installation shaft or bolt edge to disk body 1 and through hole 3 to cause reeling and formed breach.
In the utility model specific embodiment, the angle of the inclined-plane of the outer groove 11 on the disk body 1 and disk body 1 end face and bottom surface is 45 °, and the angle of the inclined-plane of the internal groove 31 of through hole 3 and the end face of disk body 1 and bottom surface is 45 °.
Among the embodiment of the present utility model, the internal diameter of tapped hole 2 is 43.7mm.The aperture of through hole 3 is 16.2 mm.
The working principle of screwed flange of the present utility model is identical with prior art, difference is that existing screwed flange is not to the jointing place of end face and the bottom surface and the sidewall of disk body 1, and any processing is done in the jointing place of the end face of through hole 3 madial walls and disk body 1 and bottom surface, and the utility model groove 11 and internal groove 31 outside Liang Chu is provided with respectively, avoid when installation shaft or bolt edge to disk body and through hole to cause reeling and formed breach, improved processing effect.
