Background technique
Threeway is the Common Component of water, gas, oil line pipe, be widely used in worker, agricultural and building industry, existing threeway generally is that material is the foundry goods of cast iron, cast steel, malleable iron, they generally are shaped on internal thread or outside thread at pipe end, be spirally connected with pipeline, have advantage easy to connect is installed, but they only are fit to make small-bore threeway, can not adapt to the large diameter pipeline requirement.The threeway lock ring bolt of common threeway and O-ring seal are on the same axis, and in course of working, because the error of screw thread and hole malalignment, the lock ring bolt is subjected to the restriction meeting secundly of screw thread that lock ring hole is leaked.
Summary of the invention
The purpose of this utility model is to provide a kind of adaptation bore scope wide, can be used for the profiled tee joint of pipeline repairing, overhaul, technological transformation, and this threeway is connected with pipeline, sandwich valve, when transport line is carried out the shutoff operation, is used for the meson stream in the transporting pipeline; Treat that the shutoff construction finishes, and is used for the plug-hole of pipeline.
The purpose of this utility model is achieved through the following technical solutions:
Profiled tee joint, comprise that bottom plate, three-way body, fixed tube, plug are stifled, snap ring, suspension ring, blind flange, bottom plate is connected with three-way body, three-way body and fixed tube weld together, it is stifled to be provided with plug between fixed tube and the flange, plug is stifled to be connected by snap ring with flange, and blind flange is fixed on the flange by stud bolt and nut, and blind flange is provided with suspension ring.
Aforesaid flange is provided with and is used for fixing the stifled pin of plug, is provided with the metal ring seal ring between blind flange and the flange.
Aforesaid plug is stifled, and to be provided with O RunddichtringO, steel ball, sealing seat, spring, spring washer, plug plug wire stifled.
Aforesaid snap ring is provided with the snap ring hook, the snap ring hook is connected with an end of snap ring by snap ring hook nut, the other end of snap ring is adjusted screw rod with snap ring and is connected, and snap ring is adjusted on the screw rod snap ring plug, snap ring silk braid, snap ring silk braid copper packing, support ring, Yx seal ring are housed.
Advantage of the present utility model and effect are:
1. four lock ring holes of the present utility model encircle sealing with Yx polyamine fat more, and its good sealing effect makes things convenient for situations such as medium, wax layer in the detecting tube.
2. the utility model is easy for installation, is convenient to get rid of the fault of cleaning in the pipe such as wiper, maintenance, detection facility.
3. the utility model is provided with the hook nut, advances snap ring, guarantees coaxality, improves sealing effect.

Embodiment
With reference to the accompanying drawings the utility model is elaborated.
As shown in the figure, the utility model include that bottom plate 1, three-way body 2, fixed tube 3, plug are stifled 5, nut 7, stud bolt 8, snap ring 9, suspension ring 11, blind flange 12.The bottom plate of this threeway is connected with three-way body, three-way body and fixed tube weld together, form weld bond 4, it is stifled to be provided with plug between fixed tube and the flange, flange is provided with and is used for fixing the stifled pin 25 of plug, the stifled O RunddichtringO 6 that is provided with of plug, steel ball 13, sealing seat 14, spring 15, spring washer 16, plug plug wire stifled 17, plug is stifled to be connected by snap ring 9 with flange, snap ring is provided with the snap ring hook, the snap ring hook is connected with an end of snap ring by snap ring hook nut 18, the other end of snap ring is adjusted screw rod 24 with snap ring and is connected, snap ring is adjusted on the screw rod snap ring plug 19 is housed, snap ring silk braid 20, snap ring silk braid copper packing 21, support ring 22, Yx seal ring 23, blind flange is fixed on the flange by stud bolt 8 and nut 7, is provided with metal ring seal ring 10 between blind flange and the flange, and blind flange is provided with suspension ring 11.
Programmed sequence of operations
1. unclamp bolt 8, unload blind flange 12; Withdraw from snap ring 9, take out plug stifled 5;
2. check steel ball 13, if having dirt sand, corrosion to clean out; Check whether sealing seat spare is intact, if distortion or scuffing should more renew; Adjust stifled 17 positions of plug plug wire, the up and down scope 6～12mm of steel ball is advisable; Check and stop up 5 surfaces, if jagged corrosion will be cleaned out;
3. check whether freely snap ring adjustment screw rod 24 is sent to, if there is stuck phenomenon to answer lubricating oil filling or repairing;
4. the point of choosing on the pipeline circle is as the shutoff setting, and position of opening does not have the place of weld seam, with the weld seam equating on the pipe, and the threeway centering, assurance level ± 0.02 welds, and annulus is welded in vertical weldering (horizontal both sides) more earlier;
5. bulge test;
6. after shutoff finished, following plug was stifled, locks snap ring, removes equipment such as plugging device, connector, sandwich valve, has filled up sealing gasket 10, covers blind flange 12, evenly tight firm bolt;
7. do anticorrosive coat.
It should be noted that: in the assembly process, must clean out lock ring hole and three-way body endoporus annular groove burr, dirt sand in order to avoid scratch seal ring; Install when stopping up, be coated with glycerine, frictional force when sending into obstruction with minimizing in the side; If oil leakage phenomenon occurs, please check whether sealing gasket, seal ring, sealing seat damage, then more renew if damage.
