Description
Technical field
The utility model relates to piping flange, and more particularly, it relates to one specifically docking petroleum pipeline flange group of good performance.
Background technique
Flange is again flange plate or bead, flange be make pipe and pipe and and the interconnective part of valve, be connected to pipe end.Flange is paired use generally, and pipeline, by arranging mutually corresponding mounting hole, is well connected through mounting hole by links such as bolts by a pair flange.
Piping flange comprises the connecting tube that flange plate is integrally connected with it with one end, described flange plate offers some mounting holes, connecting tube is socketed on pipeline, then through welding or the fastening connection reaching a pipeline and a flange of other fastening pieces, two the pipeline combined and flange are docked by flange plate after fixed by the fastening piece such as screw or nut.
Piping flange normally uses in pairs, wherein the connecting tube of female piping flange is connected with valve body, the flange plate of sub-pipes flange is connected with female piping flange and its connecting tube is connected with pipeline, and then sub-pipes flange is also the main portions occurring to leak when being connected with female piping flange, usually caused by the circumferential play of sub-pipes flange and female piping flange and radial-play.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide petroleum pipeline flange group, and it effectively can solve the leakage problem that the sub-pipes flange of prior art and female piping flange cause due to the circumferential play when docking and radial-play.
For achieving the above object, the utility model provides following technological scheme: a kind of petroleum pipeline flange group, comprise sub-pipes flange and female piping flange, the sub-connection pipe that described sub-pipes flange comprises sub-flange plate and is attached thereto, female connecting tube that described female piping flange comprises female flange plate and is attached thereto, described sub-flange plate is provided with concentric frustoconic shape positioning block, described female flange plate is provided with frustoconic shape locating slot that is concentric and that match with described frustoconic shape positioning block, the end face that the relatively female flange plate of described sub-flange plate is relative is provided with annular lug, the end face that described female flange plate phase antithetical phrase flange plate is relative is provided with the annular groove matched with described annular lug.
By adopting technique scheme, when making sub-pipes flange and the docking of female piping flange by frustoconic shape positioning block and frustoconic shape locating slot, can by the self character of this shape of frustoconic shape in the process of docking to the heart, and its radial-play can be prevented; By arranging annular lug and annular groove, make sub-pipes flange and female tube method can prevent the rotation play of circumference, so just achieve and prevent the radial-play between sub-pipes flange and female piping flange and circumferential play, making their better connective stabilities when realizing connecting, greatly reducing the generation that the problem of leaking occurs.
The utility model is set to further: the sidewall of described frustoconic shape positioning block is provided with the first seal groove, and the sidewall of described frustoconic shape locating slot is provided with the second seal groove wanting with described first seal groove to mate.
The utility model is set to further: the seamed edge of described annular lug is all rounded down.
Compared with prior art, the utility model has the advantage of: by being arranged on frustoconic shape positioning block on sub-flange plate and annular lug, frustoconic shape locating slot on female flange plate and annular groove, achieve and prevent sub-pipes flange and female piping flange from when docking, radial-play and circumferential play occurring; The sealing of sub-pipes flange and female piping flange is further enhanced by the first seal groove and the second seal groove; By the fillet arranged at the seamed edge of annular lug, make annular lug and annular groove to becoming more smooth and easy time slotting.
Accompanying drawing explanation
Fig. 1 is the sub-pipes flange of the utility model petroleum pipeline flange group embodiment and the docking scheme of female piping flange;
Fig. 2 and Fig. 3 is the sub-pipes flange of the utility model petroleum pipeline flange group embodiment and female piping flange exploded view.
In figure, 1, sub-pipes flange; 11, frustoconic shape positioning block; 111, the first seal groove; 12, annular lug; 13, the first through hole; 2, female piping flange; 21, frustoconic shape locating slot; 211, the second seal groove; 22, annular groove; 23, the second through hole.
Embodiment
Referring to figs. 1 through Fig. 3, the embodiment of the utility model petroleum pipeline flange group is described in further details.
The utility model comprises sub-pipes flange 1 and female piping flange 2, the sub-connection pipe that described sub-pipes flange 1 comprises sub-flange plate and is attached thereto, female connecting tube that described female piping flange 2 comprises female flange plate and is attached thereto, described sub-flange plate is provided with concentric frustoconic shape positioning block 11, described female flange plate is provided with frustoconic shape locating slot 21 that is concentric and that match with described frustoconic shape positioning block 11, the sidewall of described frustoconic shape positioning block 11 is provided with the first seal groove 111, the sidewall of described frustoconic shape locating slot 21 is provided with the second seal groove 211 wanting with described first seal groove 111 to mate, the end face that the relatively female flange plate of described sub-flange plate is relative is provided with annular lug 12, the seamed edge of described annular lug 12 is all rounded down, the end face that described female flange plate phase antithetical phrase flange plate is relative is provided with the annular groove 22 matched with described annular lug 12.
By said structure and accompanying drawing known, female connecting tube of female piping flange 2 is connected with the valve body for petroleum industry, and its female flange plate docks with the sub-flange plate of sub-pipes flange 1, afterwards sub-connection Guan Zaiyu pipeline connect.
When sub-pipes flange 1 is connected with female piping flange 2, the relatively female flange plate direction docking of sub-flange plate, when sub-pipes flange 1 and female piping flange 2 being docked by frustoconic shape positioning block 11 and frustoconic shape locating slot 21, can by the self character of this shape of frustoconic shape in the process of docking to the heart, and its radial-play can be prevented; By arranging annular lug 12 and annular groove 22, make sub-pipes flange 1 and female tube method can prevent the rotation play of circumference, so just achieve and prevent the radial-play between sub-pipes flange 1 and female piping flange 2 and circumferential play, by being arranged on the first through hole 13 of sub-flange plate and the second through hole 23 be arranged on female flange plate, with bolt, their locking can be achieved axial locking; So just achieve axial, radial, the circumferential complete convenient location of sub-pipes flange 1 and female piping flange 2, prevent the leakage problem because all directions play between them causes; Further, by the first seal groove 111 and the second seal groove 211, can between seal ring is set, greatly increase sealing; Further, by the fillet arranged at the seamed edge of annular lug 12, make annular lug 12 and annular groove 22 to becoming more smooth and easy time slotting.
