Description
Technical field
The utility model belongs to valve field, particularly relates to a kind of stopcock remote control.
Background technique
At present, the application of the various high-voltage type stopcocks in oil field is very general, and stopcock unlatching is closed, still adopts the method for artificial crowbar operation can not meet field operation requirement, and on-the-spot needs can realize the closed stopcock control gear of frequent unlatching.Domestic existing product is as hydraulic drive type stopcock, pneumatic type stopcock, electromagnetic type stopcock, though frequently can open closed at operation field, effect is also good, and adaptive shape stopcock remote control exploitation has just just started to explore.
Domestic plug valve device extensively adopts artificial crowbar, when mesolow valve opening closes, has feature simply and easily.The problem of this mode of operation is in fracturing work, when high pressure cock valve controls, needs several operator work compound simultaneously, just can complete closure or openness.And larger condition is proposed to operating space.When massive hydraulic fracture operation, this mode will cause manufacturing efficiency low, and occur that special fortuitous event can not feed back in time, personnel labor intensity is higher and dangerous.Domestic current employing with pneumatic, surge, the cost of the stopcock of motorized motions head is general higher, and the expense of driving head is still high.Be applied to the stopcock without the need to frequent operation, there is larger wasting of resources phenomenon.Great number cost when demolition and maintenance stopcock, universal use has suitable difficulty.
In sum, external stopcock is not suitable for domestic pressure break field condition, and fixed driving head stopcock scheme does not solve the simplification and high cost problem that oil field uses.So control gear needs based on oil field at home actual job situation, to solve stopcock tele-control system and to carry out adaptive requirement with stopcock.
Model utility content
The purpose of this utility model is to provide a kind of stopcock remote control, is intended to the working method of the artificial crowbar solving existing stopcock, the high and unsafe problem of intensity of workers.
The utility model is achieved in that a kind of stopcock remote control comprises PLC, hydraulic power unit electromechanical double power module, two outlet-rod hydraulic cylinder, stopcock driving mechanism;
Described PLC and described hydraulic power unit electromechanical double power model calling, for driving described hydraulic power unit electromechanical double power module, described two outlet-rod hydraulic cylinder and described hydraulic power unit electromechanical double power model calling;
Described stopcock driving mechanism comprises carousel gear and tooth bar, and described carousel gear is arranged in the tap handle of described stopcock, and described tooth bar is arranged on the cylinder body of described two outlet-rod hydraulic cylinders, described tooth bar and described carousel gear engagement driving.
Further, described two outlet-rod hydraulic cylinders are symmetricly set on the both sides of described carousel gear.
Further, described two outlet-rod hydraulic cylinders can also adopt oil hydraulic motor.
The utility model with PLC hydraulic control pumping plant electromechanical double power module for two outlet-rod hydraulic cylinder provides power, two outlet-rod hydraulic cylinder provides the tap handle of motivational drive stopcock to rotate for stopcock driving mechanism, dynamical stability is reliable, can meet the operating environment of various complexity; Simple structure, be convenient to the maintenance in later stage, stability is strong.
Accompanying drawing explanation
Fig. 1 is the structural representation of the stopcock remote control that the utility model embodiment provides;
In figure: 1, PLC; 2, hydraulic power unit electromechanical double power module; 3, two outlet-rod hydraulic cylinder; 4, stopcock driving mechanism.
Embodiment
For model utility content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.
As shown in Figure 1, the utility model is achieved in that a kind of stopcock remote control comprises PLC 1, hydraulic power unit electromechanical double power module 2, two outlet-rod hydraulic cylinder 3, stopcock driving mechanism 4;
Described PLC 1 is connected with described hydraulic power unit electromechanical double power module 2, and for driving described hydraulic power unit electromechanical double power module 2, described two outlet-rod hydraulic cylinders 3 are connected with described hydraulic power unit electromechanical double power module 2;
Described stopcock driving mechanism 4 comprises carousel gear and tooth bar, and described carousel gear is arranged in the tap handle of described stopcock, and described tooth bar is arranged on the cylinder body of described two outlet-rod hydraulic cylinders 3, described tooth bar and described carousel gear engagement driving.
Further, described two outlet-rod hydraulic cylinders 3 are symmetricly set on the both sides of described carousel gear.
The utility model embodiment have employed and assists spur gear to drive and the carousel gear on the positioning device of stopcock handwheel adaptation with two outlet-rod hydraulic cylinders of bilateral balanced type, with PLC hydraulic control pumping plant electromechanical double power module for two outlet-rod hydraulic cylinder provides power, two outlet-rod hydraulic cylinder provides the tap handle of motivational drive stopcock to rotate for stopcock driving mechanism, the dynamical stability that two outlet-rod hydraulic cylinder provides is reliable, can meet the operating environment of various complexity; Simple structure, be convenient to the maintenance in later stage, stability is strong; Sound construction, stable performance.
Further, described two outlet-rod hydraulic cylinders can also adopt oil hydraulic motor, and by gear transmission, drive the clamp device on stopcock handwheel, thus control cock valve is opened under hyperbaric environment, employing oil hydraulic motor is power source, can provide larger moment of torsion.Avoid the problem of not opening that power difference is brought when job execution.
The above is only to preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
