Abstract
An automatic opening and closing device for a valve of a hydraulic tong belongs to the technical field of workover machinery of oil and gas fields. The hydraulic clamp comprises a hydraulic clamp body, a hydraulic clamp piston, a hydraulic clamp valve switch handle, a hydraulic clamp piston connecting rod and a hydraulic clamp cover, wherein the hydraulic clamp body is cylindrical and is fixedly connected to the hydraulic clamp body through bolts; an oil inlet of the hydraulic cylinder body is connected with an oil inlet pipeline in a threaded manner, an oil outlet of the hydraulic cylinder body is connected with an oil outlet pipeline in a threaded manner, the oil inlet pipeline and the oil outlet pipeline are communicated with a liquid path electromagnetic control valve pipeline, and the liquid path electromagnetic control valve is connected with a hydraulic source; the liquid path electromagnetic control valve is connected with the electromagnetic valve control button by adopting a cable wire. The utility model provides a traditional hydraulic tong must rely on personnel to operate the function of opening and shutting the valve, reduces intensity of labour. The potential safety hazard that exists under the condition of not breaking the power liquid way when eliminating personnel's operation, it is simple to maintain, and the operation is reliable, and the fault rate is low.
Description
Technical field
The utility model relates to a kind of hydraulic tongs valve recloser, belongs to oil gas field well workover field of mechanical technique.
Background technology
At present, hydraulic tongs is on oilfield downhole operation, to unload the indispensable construction machinery instrument of tubing string screw thread, and most employing the in domestic each oil field be take manual operation as main hydraulic tongs.Thisly with personnel, operate to realize the hydraulic tongs that unloads tubing string screw thread, jaw rotary part has manual openning and dosing bib, rotary part causes machinery to hurt sb.'s feelings when preventing on tubing string shackle, but in use must just can make tubing string enter hydraulic tongs by special messenger's openning and dosing bib, there is great potential safety hazard, and exist operational sequence loaded down with trivial details, the problems such as labour intensity is large.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of hydraulic tongs valve recloser, its objective is the hydraulic power of utilizing hydraulic tongs itself to use, adopt small-sized piston-type hydraulic cylinder to control hydraulic pipe wrench valve, realize remote switch, solve the function that traditional hydraulic tongs must dependence personnel operates openning and dosing bib, the potential safety hazard existing when elimination personnel operate simultaneously and reduce the problem of labour intensity.
A kind of hydraulic tongs valve recloser, hydraulic cylinder body is cylindrical, hydraulic cylinder body is bolted to connection on hydraulic tongs body, liquid cylinder piston is installed in hydraulic cylinder body, liquid cylinder piston connecting rod and liquid cylinder piston are integrated, and liquid cylinder piston connecting rod top is porose to be connected with bolt with hydraulic tongs valve handle; The oil-in of hydraulic cylinder body and feed line screwed connection, the oil-out of hydraulic cylinder body and flow line screwed connection, feed line and flow line Yu Ye road solenoid electric valve pipeline are communicated with, liquid road solenoid electric valve connecting fluid potential source; Liquid road solenoid electric valve adopts cable conductor to be connected with solenoid control button.
The beneficial effect of advantage of the present utility model and generation is: solve the function that traditional hydraulic tongs must dependence personnel operates openning and dosing bib.Solve operating personnel's frequent operation switch, reduce labour intensity.Potential safety hazard when elimination personnel operate in the situation that not disconnecting power fluid road, maintaining is simple, reliable, failure rate is low.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of hydraulic tongs valve recloser, hydraulic cylinder body 1 is cylindrical, hydraulic cylinder body 1 is bolted to connection on hydraulic tongs body, the interior installation liquid cylinder piston 2 of hydraulic cylinder body 1, liquid cylinder piston connecting rod 3 is integrated with liquid cylinder piston 2, and liquid cylinder piston connecting rod 3 tops are porose to be connected with hydraulic tongs valve handle 8 use bolts; Oil-in 4 and feed line 5 screwed connections of hydraulic cylinder body 1, oil-out 6 and flow line 7 screwed connections of hydraulic cylinder body 1, feed line 5 and flow line 7 Yu Ye road solenoid electric valve 9 pipelines are communicated with, liquid road solenoid electric valve 9 connecting fluid potential sources 11; Liquid road solenoid electric valve 9 adopts cable conductor to be connected with solenoid control button 10.
The hydraulic power supply that starts hydraulic power unit or connection workover rig itself, makes hydraulic tongs in above unloading the duty for the treatment of of tubing string screw thread, and meanwhile, hydraulic tongs automatic gear shift apparatus is full of hydraulic power in treating duty.During hydraulic tongs work, press the high speed button on solenoid control button 10, liquid road solenoid electric valve 9 is opened, hydraulic power oil enters and is full of hydraulic cylinder body 1 oil suction chamber through feed line 5, promote liquid cylinder piston 2 and liquid cylinder piston connecting rod 3 descending, thereby promote hydraulic tongs valve handle 8, open valve.Otherwise, hydraulic tongs completes shackle while exiting, press the low speed button on solenoid control button 10, liquid road solenoid electric valve 9 is opened, hydraulic power oil enters and is full of hydraulic cylinder body 1 oil suction chamber through flow line 7, promote liquid cylinder piston 2 and liquid cylinder piston connecting rod 3 up, thereby promote hydraulic tongs valve handle 8, open and close, realize the object of hydraulic tongs valve remote switch.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
