Abstract
The utility model relates to a hydraulic large vice torque controller, which is used for the screwing-on and screwing-off work of drill tools during the well drilling process of the oilfield. The utility model comprises a casing with an oil inlet and an oil drain, a seal valve mounted inside an inner cavity, adjusting screws, etc. The torque controller can effectively and conveniently control the torque of the hydraulic large vice and have simple structure and low cost.
Description
The utility model relates in a kind of Process of Oil Well Drilling, the torque control device of used hydraulic tongs in button, the shackle operation on drilling tool.
The power tongs of button, shackle generally is power with hydraulic pressure on the drilling tool that situ of drilling well is used, operate on one side by the driller, observe pressure meter on one side, so be difficult to grasp just right moment of torsion, in case over proof moment of torsion, tend to damage drilling tool or hydraulic tongs, cause unnecessary loss.In order to address this problem, the patent No. is to propose a kind of technical solution in 90226811.2 the patented technology, this scheme is by Pneumatic reversal valve, solenoid operated directional valve, electro connecting pressure gauge, formations such as relay, need gas circuit, the circuit acting in conjunction could be controlled the moment of torsion pressure of hydraulic tongs, used component are more, complex structure, in use, wherein there are parts to break down and influence its result of use, particularly circuit accessory wherein not only needs power supply, also easier breaking down in the adverse circumstances of situ of drilling well, therefore, this technology is used very undesirable at the scene.
The purpose of this utility model is for a kind of power supply, electrical accessorie of neither needing is provided, do not need gas control element and gas path device yet, simple in structure, easy to use, reliable, with low cost can be effectively, the hydraulic tongs torque control device of control torque easily.
Technical solution of the present utility model is to realize like this, detain on a kind of well drilling tool, used hydraulic tongs torque control device in the shackle operation, have oil-in that is connected with fluid pressure line and the drain tap that is connected with the oil return pipeline, its special character is that oil-in and drain tap are installed on the housing, and with the housing intracavity inter-connection, between endoceliac oil-in of shell and drain tap, seal valve is installed, seal valve and seal receptacle are closely linked by spring, the spring other end combines by spring bearer plate and adjusting screw(rod), adjusting screw(rod) is installed on the gland by screw thread, and gland is installed on the shell.
In above-mentioned hydraulic tongs torque control device, its special character also is: seal valve is installed in to be set upright in the support.Between seal valve and the seal receptacle sealing mat is installed.
The utility model has the advantages that the moment of torsion that to control hydraulic tongs effectively, and can regulate the scope of control torque easily, installation, easy to use, simple in structure, with low cost.
Fig. 1 is a sectional structure chart of the present utility model.
Be described further below in conjunction with accompanying drawing: the sealing surface inside the inner chamber of housing 34 is ground smooth smooth (perhaps installing sealing mat), grind the sealing surface of seal valve 8 smooth smooth, with seal valve 8, spring 6, spring bearer plate 7 is packed into and is set upright in the inner chamber of the shell 3 of packing into together again in the support, adjusting screw(rod) 1 is installed on the gland 2 by screw thread, gland 2 is installed on the shell 3 by screw thread or screw, oil-in 10 adopts the threeway form, its straight-through two ends are connected with the hydraulic tongs hand-operated direction valve with hydraulic pump respectively, its end by thread connection on shell 3, drain tap 9 is straight-through pipe short circuit, on shell 3, the other end is connected on the oil return pipeline of hydraulic tongs one end by thread connection.Turn adjusting screw(rod) 1 can be regulated the moment of torsion of hydraulic tongs.In use, when the moment of torsion of hydraulic tongs surpassed predetermined value, seal valve 8 will be pressed off, high-pressure and hydraulic oil is by oil-in 10, and housing 3 inner chambers, drain tap 9 are let out and got back in the oil return pipeline, the moment of torsion of hydraulic tongs can not raise again, thereby can guarantee the safety of drilling tool and hydraulic tongs.
Claims (3)
1, button on a kind of well drilling tool, all hydraulic tongs torque control devices in the shackle operation, have oil-in that is connected with fluid pressure line and the drain tap that is connected with return line, it is characterized in that, oil-in and unloading port are installed on the housing, and with the housing intracavity inter-connection, between endoceliac oil-in of shell and drain tap, seal valve is installed, seal valve and seal receptacle are closely linked by spring, the spring other end combines by spring bearer plate and adjusting screw(rod), adjusting screw(rod) is installed on the gland by screw thread, and gland is installed on the shell.
2, hydraulic tongs torque control device according to claim 1 is characterized in that seal valve is installed in to set upright in the support.
3, hydraulic tongs torque control device according to claim 1 and 2 is characterized in that between seal valve and the seal receptacle sealing mat being installed.
