Abstract
The invention discloses a branch pipeline connection drilling device. The branch pipeline connection drilling device comprises a valve, a sealing pipe sleeve and a drill, wherein the valve and the sealing pipe sleeve are fixedly connected and are kept sealed, and the drill is installed in the sealing pipe sleeve. During branch pipeline connection, the valve is fixedly connected to a pipeline in a sealing mode; after the sealing pipe sleeve is connected with the valve in a sealing mode, the valve is in a completely open state, the drill penetrates through the valve to drill holes in the pipeline, and the sealing pipe sleeve and the drill are kept sealed so that the situation that fluid in the pipeline overflows due to drilling can be avoided. The branch pipeline connection drilling device has the advantages that normal operation of a main pipeline is not affected by branch pipeline connection, cost is reduced, the structure is simple, operation is convenient to carry out, the sealing pipe sleeve and the drill are easy to dismount after drilling, and efficiency is improved.
Description
Technical field
The present invention relates to the boring interconnection technique field in pipeline connection technology field, particularly pipeline.
Background technology
The connection of lateral, is generally reserved joint in main pipeline, or cutting off main pipeline installs three-way connection additional.Connection, tap for pipeline in service, generally need to stop the operation of pipeline, even needs to discharge ducted fluid; In connection procedure, easily make leaking of fluid in pipeline, pollute or waste.Also in some cases, three-way connection installation difficulty is large, and cost is high.Meanwhile, the operating efficiency of these connected modes is lower, has affected the operation of pipeline simultaneously, and user is caused to a lot of inconvenience.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of drilling equipment that can prevent leakage in the situation that not stopping conduit running.
Duct shunting drilling equipment of the present invention comprises, valve, and sealed tube and drill bit, valve is fixedly connected with sealed tube and keeps sealing, and drill bit is loaded in sealed tube.
Sealed tube of the present invention comprises body, upper cover and piston, and upper cover can be passed through in piston upper end, and piston lower end is connected with drill bit, and sealing ring is housed on piston, keeps sealing with body.
The bossed step of piston middle part tool of the present invention, is equipped with sealing ring on step.
Piston of the present invention upper end is connected with drive unit, can in sealed tube, move back and forth and rotate, and makes drill bit along sealed tube and valve axially-movable and rotation, implements boring.
During duct shunting, valve seal is fixedly connected on pipeline, after sealed tube is connected with valve seal, valve is in complete opening, drill bit is holed to pipeline through valve, keeps sealing between sealed tube body and piston, and the fluid in pipeline can not overflow because of boring.After having holed, drill bit exits valve, and valve-off unloads after sealed tube and drill bit, i.e. conduit connectable branch.
The present invention has the following advantages:
The tap that adopts the present invention to carry out pipeline does not affect the normal operation of main pipeline, has reduced cost;
The present invention is simple in structure, easy to operate;
After having holed, sealed tube and drill bit are easy to retract, and have improved efficiency.
Accompanying drawing explanation
Fig. 1 structural representation of the present invention
Fig. 2 sealing ring is installed on the schematic diagram of sealed tube upper cover
In figure, pipeline 1, valve 2, drill bit 3, sealed tube 4, sealing ring 5, upper cover 6, step 7, piston 8.
The specific embodiment
See Fig. 1, during duct shunting, first valve 2 is fixedly connected by welding on pipeline 1, drill bit 3 packs on the piston 8 in sealed tube 4, sealed tube 4 is tightly connected with valve 2 by screw thread or flange etc., complete Open valve 2, and drill bit 3 is holed through 2 pairs of pipelines of valve; Because the step 7 of piston 8 is equipped with sealing ring 5, between sealed tube 4 tube walls and piston 8, keep sealing, the fluid in pipeline can not overflow because of boring.After having holed, drill bit 3 exits valve 2, and valve-off 2 prevents that fluid from leaking.Unload after sealed tube 4 and drill bit 3 connecting pipe branch on valve 3.
See Fig. 2, sealing ring 5 also can be pacified the upper cover 6 that is packaged in sealed tube 4, makes to keep sealing between sealed tube 4 and piston 8.
Claims (3)
1. duct shunting drilling equipment, is characterized in that, it comprises valve, sealed tube and drill bit, and valve is fixedly connected with sealed tube and keeps sealing, and drill bit is loaded in sealed tube.
2. duct shunting drilling equipment according to claim 1, is characterized in that, described sealed tube comprises body, upper cover and piston, and upper cover can be passed through in piston upper end, and piston lower end is connected with drill bit, and sealing ring is housed on piston.
