Description
Technical field
The present invention relates to the PE gas pipeline hole making drill that a kind of opening diameter is not more than the Operating Pressure of 63mm, belong to pipeline tapping instrument, be mainly applicable to buried with the perforate of polyethylene saddle type bypass pipe fitting Operating Pressure.
Background technology
In the time of buried gas pipeline operation, busy need to be on gas pipeline connecting bypass pipe, under normal circumstances, first stop the supple of gas or steam to gas pipeline, traditional method is to cut off gas pipeline, a three-way connection is installed, then bypass pipe is connected on three-way connection; Be generally now in gas pipeline on perforate, then bypass connecting pipe is installed, by bypass connecting pipe connecting bypass pipe.Its shortcoming is that the coverage of stopping the supple of gas or steam is large, and economic loss is many, executes man-hour requirement whole piece pipeline is dug out, very trouble.Therefore, need the drilling tool of a kind of (not stopping the supple of gas or steam) with pressure operation of design.
Summary of the invention
The object of the invention is the shortcoming in order to overcome prior art, provide a kind of without stopping the supple of gas or steam, easy construction, perforate speed is fast, safety coefficient is high, the PE gas pipeline hole making drill of the Operating Pressure that working area is little.
The technical scheme of the PE gas pipeline hole making drill of Operating Pressure of the present invention is: comprise a T-shaped spanner, T-shaped spanner connects seal and opening cap, seal and opening cap connects saddle type bypass, saddle type bypass matches with gas pipeline with pressure, it is characterized in that described seal and opening cap comprises cap and the outer cap of sealing in sealing, in sealing, cap matches with T-shaped spanner by locating slot, in sealing, cap is threaded with the outer cap of sealing by positioning key, described saddle type bypass is electric smelting bypass pipe, on electric smelting bypass pipe, tube connector is set, on one sidewall of tube connector, breather pipe is set, the head outer wall of tube connector is shaped with external screw thread, the lower inner wall of the outer cap of sealing is shaped with internal thread, internal thread matches with external screw thread, in tube connector, place bore cutter, bore cutter is connected with T-shaped spanner, electric smelting bypass pipe matches with gas pipeline with pressure by suspension bracket, and fixed by fastener.
The invention discloses a kind of PE gas pipeline hole making drill of Operating Pressure, when construction, first cap in T-shaped spanner and sealing is assembled, cap in sealing and the outer cap of sealing are assembled simultaneously, reach the effect of location and sealing, again the electric smelting bypass pipe and the gas pipeline with pressure that are equipped with bore cutter are assembled and electric fusion welding, electric smelting bypass pipe is stayed on gas pipeline with pressure, then T-shaped spanner, in sealing, cap and the assembly that seals outer cap are by sealing the internal thread of outer cap and the external screw thread of tube connector is connected and seals, simultaneously, bore cutter is assembled to the head end of T-shaped spanner, clockwise rotate again T-shaped spanner, after the blade of bore cutter acts on gas pipeline with pressure, increase gradually the rotation dynamics on T-shaped spanner, until pipeline tapping completes.After perforate completes, rotate counterclockwise T-shaped spanner until bore cutter is rotated to the top end of electric smelting bypass pipe, now take off each drilling tool accessory, outer sealing cap and tube connector are tightened, tube connector blocks, and ventilates by breather pipe, and perforate completes.This programme has solved the difficult problem that gas pipeline is difficult for gas leakage in perforate or perforate process under running status with pressure, thereby realize the Fast Installation ventilation of pipeline, be a kind of safe, simple to operate, with low cost, should acute strong drilling tool, there is obvious technical advantage and economic worth.
The PE gas pipeline hole making drill of Operating Pressure of the present invention, the both sides that described fastener is included in electric smelting bypass pipe arrange holder, and fixing hole is set in holder, and fixing hole fixes by hold-down screw and suspension bracket, adopt screw fixed structure simple, processing ease.Described bore cutter comprises that top contains hexagonal hole, and bore cutter external wall of upper portion contains bore screw, and boring cutting edge of a knife or a sword limit is contained in bore cutter bottom, the bottom of T-shaped spanner arranges six square toes, six square toes and hexagonal hole with match, bore cutter rotation in the time of boring, six square toes are non-slip, and boring is reliable.Described bore cutter width K≤63mm.The diameter of namely perforate is generally no more than 63mm, by the perforate pressure control of gas pipeline with pressure within the specific limits, avoids perforate large, causes the excessive explosion of gas pipe pressure with pressure.
