Background technology
Be accompanied by the national economy high speed development, oil and natural gas consumption continues soaring, already and will continue to form conveying crude oil, the key pipe network of natural gas and product oil, especially clean energy resource-natural-gas transfer pipeline develops to high pressure (12MPa) heavy caliber direction, pipe material is to the above high-strength material development of X80, the maximum working pressure (MWP) of existing tapping machine is all below 10MPa, manifold pressure acts on the tapping machine transmission mechanism during perforate operation, tapping machine gearing friction resistance is strengthened, the big heavy discount of power of output can't be finished the perforate operation under the pressure piping (12MPa).
The utility model content
Technical problem to be solved in the utility model provides a kind of power output that can improve tapping machine, strengthens the heavy caliber high pressure tapping machine pressure equaliser of perforate work capacity.
For solving the problems of the technologies described above, the utility model provides a kind of heavy caliber high pressure tapping machine pressure equaliser, comprises that the upper end connects tapping machine main frame oil-in, the lower end connects the accumulator that perforate connects the case gas port.
Further, described accumulator upper end comprise upper end reducer union, the upper end switch valve that is connected with the upper end reducer union, the last end connector that is connected with the upper end switch valve that connects the accumulator shell and be arranged on the lower end reducer union and the lower end switch valve between Pressure gauge, the described end connector of going up connects flexible pipe, and flexible pipe is connected to tapping machine main frame oil-in.
Further, described accumulator lower end comprises the lower end reducer union that connects the accumulator shell, the lower end switch valve that is connected with the lower end reducer union, reaches the following end connector that is connected with the lower end switch valve, described end connector down connects flexible pipe, and flexible pipe is connected to perforate and connects the case gas port.
Further, described accumulator is bladder type hydropneumatic accumulator or piston cylinder formula accumulator.
Further, described accumulator is connected on the tapping machine main frame body all the time.
A kind of heavy caliber high pressure tapping machine pressure equaliser that the utility model provides can utilize the pressure of pipeline medium, makes tapping machine when the pipeline tapping operation, produces normal pressure when pipe medium pressure affacts the tapping machine main shaft.The perforate of pressure medium by the lower end connects the case gas port and is passed in the accumulator, after pressure medium in the accumulator expands leather bag the hydraulic oil oil pressure is raise, again hydraulic oil is pressed in the tapping machine main frame by upper end tapping machine main frame oil-in, originally be full of hydraulic oil in the tapping machine main frame, because the oil pressure of the hydraulic oil in the accumulator raises, make the oil pressure and the pipe medium pressure of tapping machine body reach unanimity, thereby negative function normal pressure on the tapping machine main shaft partly, reduce resistance by the lead-screw drive mechanism of main shaft normal pressure generation, make tapping machine perforate on can pipeline under the equal feed power output situation in high pressure more, improve the power output of tapping machine, strengthened the work capacity of tapping machine.
