Abstract

A pipe continuous diverter comprises a pipe with a tube screw thread on both ends. The pipe is provided with one big and one small screw thread split pipe joints, which is provided with a comminuted screw thread cap with an inner gasket. The utility model also comprises a valve matching the pipe screw thread, an external joint, a prolonged drilling bit with a big head and a small handle. The utility model also comprises a long blocking head with a shoot-through hole in central part of the disk, which is comminuted with the external joint and equipped with a hex disk and no square end, two washers and the packing sets. The utility model is required to be fixed firmly on the pipe split connector described in patent number ZL02235228.7. The drill stock is clamped by a drill device before pressing into a drill through pipe wall, followed by backing the drilling bit out of the valve, shutting down the valve core, remaining the valve and removal of the pipe and the drill device. Thus continuous shunt is realized and drilling dust is removed effectively. Also valve blocking is prevented.

Description

Pipeline is the stopping transportation shunt not

Technical field

The utility model relates to a kind of pipeline diverting means, is used to cooperate the contained pipeline shunting connector of patent No. ZL02235228.7.Sealing boring when stopping transportation does not connect split-flow opening along separate routes on various pipelines.

Background technique

A lot of pipelines need when carrying liquid along separate routes, and when directly holing along separate routes with the contained pipeline shunting connector of patent No. ZL02235228.7, the interior liquid of pipe is drilling through unavoidable splash of moment, and drilling cuttings remains in the pipeline not easy-clear, block valve easily.

Summary of the invention

The purpose of this utility model seals boring, removes the gred and the diverting means of not splash with regard to providing a kind of pipeline when stopping transportation does not connect along separate routes.

For achieving the above object, the utility model adopts following technological scheme: comprise that two has on the body, body of pipe thread the thread cap cover that supporting with it, interior band sealing gasket is arranged on two screw thread ram's horns joints of size, the joint is arranged; Comprise the big little lengthening twist bit of handle of valve, socket and head again with body screw thread coupling; Also comprise with supporting, the no square toes of socket but band outer-hexagonal dish, dish central authorities have the long plug of clear opening, two packing rings and packing.

There is pipe thread at described body two, has located two screw thread ram's horns joints of size to the greatest extent by screw thread on it, and its big Yong Yu stores slag, its I connect pressure-measuring meter, and the cap of supporting thread belt sealing gasket is arranged on the joint, and whole body is longer than the drill bit fried dough twist partly;

Described drill bit is the little lengthening twist bit of a big handle, and its footpath is more smaller than internal diameter of tube body, fried dough twist is partly slightly long than valve;

Described valve screw thread and body screw thread are supporting, and the latus rectum when opening to maximum is identical with internal diameter of tube body; The moving rod-type throughway valve of system;

Described socket is that harness cord and body screw thread are supporting;

Described packing ring internal diameter just can be slightly less than the socket internal diameter by drillstock, external diameter;

Described plug does not have square toes but band outer-hexagonal dish, dish central authorities have firm clear opening, longer slightly than plug commonly used that can be by drillstock, and screw thread and socket are supporting;

Described pipeline not stopping transportation shunt is so assembled: after being tightened to one by valve (opening to maximum), body (big joint one end is by valve), socket, with drillstock generation one packing ring, again handle coiling packing a few, drill bit is inserted towards socket one end, propelling enters in the socket packing ring and packing, drill bit just exposes valve, at last from another packing ring of drillstock substitution, advance plug, it be anchored in the socket, the compacting packing is tightened cap.

Stopping transportation shunt constituent material is not except that sealing gasket and packing for described pipeline, and other component are all made of hard, pressure-resistant material.

The utility model is the different series product of model, specification, when the described pipeline shunting connector of patent No. ZL02235228.7 on stopping transportation pipeline not along separate routes, when installing the shunting connector joint, will with supporting fastening its joint of valve of the present utility model of its joint on, with drilling tool clamp drillstock, compress into drill through tube wall, again drill bit was moved back valve, close spool, stay valve, shed drilling tool and can realize that with body stopping transportation is not connected along separate routes, and can effectively get rid of drilling cuttings, prevent the card valve.

Fig. 2 is an A-A cross-sectional schematic of the present utility model;

Perspective view when Fig. 3 is the utility model use.

Specific embodiment

Referring to Fig. 1-Fig. 3, the utility model comprises that there is the body 1 of pipe thread 7 at two, has on the body 1 on the ram's

horns joint

4 and 2,4 and 2 of two screw threads 7 of size and 6 supporting with it, interior thread cap cover 5 and 3 for sealing

gasket

51 and 31 is arranged; Comprise again and the valve 16 of body screw thread 7 coupling, socket 8 and the little lengthening twist bit of 15 big handles 14; Comprise also with supporting, the no square toes of socket but band outer-hexagonal dish 12 that there is the long plug 11 of clear opening 13 in dish central authorities; Two packing rings 9 and packing 10.

Wherein: have two ram's horns joints of size to be connected two head threads 7 place to the greatest extent on the body 1, the caliber of big joint 4 and screw thread communicate together and with the footpath with body 1.The screw thread of little joint 2 can connect with the pressure-measuring meter screw thread, uses during the superpressure shunting.Two packing ring 9 internal diameters can and can lie against in the harness cord socket 8 by drillstock 14, and packing 10 coiling drillstocks 14 fill up socket 8 residue holes again;

Drill bit 15 is longer than valve 16 ' summary, and body 1 is slightly longer than drill bit 15 again, and drillstock 14 is longer than body, and drill bit 15 has obvious step with drillstock 14 joints;

On the long plug 11 outer-hexagonal dish 12 is arranged, there is clear opening 13 in dish central authorities, and its aperture is identical with packing ring 9 internal diameters;

Valve 16 is moving rod-type throughway valve, and latus rectum is identical with body 1 internal diameter when opening to maximum;

The utility model constituent material is except that packing and sealing gasket, and other component are by hard, pressure-resistant material such as making such as high-speed steel, pottery.

Referring to Fig. 3, when the utility model uses, on valve 16 fastening taps 21, clamp drillstock 14 with drilling tool, compress into the tube wall that drills through aqueduct R, hydraulic pressure advances drilling cuttings is pushed in the large shunt joint 4 of body 1, mentioning drillstock 14 makes drill bit 15 move back valve 16 to enter body 1, throttle down 16 then, shed drilling tool and body 1 from valve 16, can realize that stopping transportation does not connect along separate routes as required on valve 16.
