Abstract
The utility model relates to a run from opposite directions shutoff tee bend with strengthening rib, include and run from opposite directions shutoff tee bend main part, its characterized in that, run from opposite directions and be equipped with two semicircular in the shutoff tee bend main part and run from opposite directions the backplate, be backplate, backplate down respectively, it is located to go up the backplate down above the backplate, go up the backplate with be equipped with the strengthening rib that the in bank distributes on the outer wall of lower backplate, go up the backplate with be equipped with closing the weld bond between the backplate down, be equipped with the taut circle bolt of transferring that the in bank distributes to closing weld bond department, the utility model discloses a set up the strengthening rib on running from opposite directions the backplate to the shutoff three -way, set up the taut circle bolt of transferring at upper and lower backplate junction, improved the function of running from opposite directions three -way backplate rigidity and correction tubular product ovality.
Description
Technical field
The utility model relates to the technical field of the connection machinery pipe fitting of the mechanical tapping shutoff operation with pressure of the large-caliber thin-walled pipeline in the field such as steel mill, chemical industry, particularly relate to and a kind ofly split shutoff threeway with stiffening rib, the effect that Calibration pipe is not justified after installation, can be played.
Background technique
In the operation of pipeline online plugging, elder generation's welding with pressure on pipeline is needed to split shutoff threeway, by forming a perforate gas-tight silo after threeway and sandwich valve and perforator assembling after having welded, under the state of sealing, press and open holes is implemented to pipeline, then insert block head from tapping, local can be implemented to the pipeline run and intercept.Implement the work of on-line production partial sealing at the oil and gas pipes run, need the pipeline ovality at shutoff position to be not more than 1%, example: Φ 1400 pipeline ovality is not more than 14mm.And diameter is greater than the low-pressure gas pipeline of Φ 1000 in general steel mill, wall thickness is all at about 6mm, and because wall thickness is partially thin, pipeline ovality is all greater than 1% of diameter, brings the difficulty that shutoff sternly maybe cannot not implement shutoff to shutoff operation.
Model utility content
The utility model is intended to solve the deficiencies in the prior art, and provide a kind of prevent pipeline thin pipe wall in pipe plugging work from occurring ovality is out of shape splits shutoff threeway.
The utility model for achieving the above object, by the following technical solutions: a kind ofly split shutoff threeway with stiffening rib, comprise and split shutoff threeway main body, it is characterized in that, described shutoff threeway main body of splitting is provided with two and semicircularly splits backplate, be respectively upper guard board, lower backplate, described upper guard board is positioned at above described lower backplate, the outer wall of described upper guard board and described lower backplate is provided with the stiffening rib of in a row distribution, be provided with involutory weld bond between described upper guard board and described lower backplate, circle bolt is adjusted in the tension that described involutory weld bond place is provided with in a row distribution.
The beneficial effects of the utility model are: the utility model, by arranging stiffening rib to splitting on backplate of shutoff threeway, arranges tension at upper and lower backplate junction point and adjusts circle bolt, improves the backplate rigidity of split tee and revises the function of tubing ovality.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is left view of the present utility model;
In figure: 1-body; 2-upper guard board; 3-splits shutoff threeway main body; 4-stiffening rib; The involutory weld bond of 5-; Circle bolt is adjusted in 6-tension; Backplate under 7-;
Be described in detail with reference to accompanying drawing below with reference to embodiment of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
A kind ofly split shutoff threeway with stiffening rib, comprise and split shutoff threeway main body 3, it is characterized in that, described shutoff threeway main body 3 of splitting is provided with two and semicircularly splits backplate, be respectively upper guard board 2, lower backplate 7, described upper guard board 2 is positioned at above described lower backplate 7, the outer wall of described upper guard board 2 and described lower backplate 7 is provided with the stiffening rib 4 of in a row distribution, be provided with involutory weld bond 5 between described upper guard board 2 and described lower backplate 7, circle bolt 6 is adjusted in the tension that described involutory weld bond place is provided with in a row distribution.
In the operation of pipeline online plugging, first on body 1, shutoff threeway is split in welding with pressure, add stiffening rib 4 splitting on the upper guard board 2 of shutoff threeway main body 3, lower backplate 7, after upper guard board 2, lower backplate 7 are involutory, define a kind of positive round mould effect, when adjusting circle bolt 6 to be strained to positive round by upper and lower tension, thin walled tube is greater than the position that ovality requires, and then implement upper guard board 2, the fixing welding of lower backplate 7 transverse joint, then circle bolt 6 is adjusted in dismounting tension.
