Background technique
The needle type valve control mode that current rock gas uses is all manually, needs people to carry out manually-operable to scene when driving a well at every turn; Defect one: consume a large amount of human and material resources and energy; Defect two: palm is completely with feel, and countless according to for referencial use, control accuracy is low.
Model utility content
The purpose of this utility model is to provide a kind of needle type valve electrohydraulic control, and it is manual for solving existing needle type valve control mode, labor intensive, material resources, the problem that control accuracy is lower.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of needle type valve electrohydraulic control, comprise the needle valve body with valve core of needle valve gear, to be connected with needle valve body and for driving the motor of valve core of needle valve pinion rotation, with motors and for driving the actuating motor of revolution, the fuel tank be connected with actuating motor, be arranged on needle valve body for detecting the displacement transducer of valve core of needle valve pinion rotation situation, and be arranged at needle valve body one end and the signal sent for received bit displacement sensor and and upper machine communication, and control the controller of actuating motor work.
Further, described fuel tank is also provided with inhalation valve.
Further, between described motor with valve core of needle valve gear, manually clutch is connected.
Further, described valve core of needle valve gear is also coaxially connected with handwheel.
In addition, institute's displacement sensors is arranged at on the gear shaft of valve core of needle valve gears meshing.
In addition, described fuel tank to be positioned at below actuating motor and coupled.
Particularly, described manual clutch one end and valve core of needle valve gears meshing; The other end and motors, and be connected for coaxial with motor.Described controller is provided with RS232 interface.
Compared with prior art, the utility model has following beneficial effect:
Application of the present utility model can save a large amount of manpower and materials, improves the operational efficiency of gas well; Displacement transducer Real-Time Monitoring and feedback, controller inside compares and computing, can accurate detection and control needle type valve aperture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, the component name that reference character is corresponding is called:
1-needle valve body, 2-motor, 3-actuating motor, 4-fuel tank, 5-displacement transducer, 6-controller, 7-inhalation valve, 8-manual clutch, 9-handwheel.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and mode of execution of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, a kind of needle type valve electrohydraulic control, comprise the needle valve body 1 with valve core of needle valve gear, to be connected with needle valve body and for driving the motor 2 of valve core of needle valve pinion rotation, with motors and for driving the actuating motor 3 of revolution, the fuel tank 4 be connected with actuating motor, be arranged on needle valve body for detecting the displacement transducer 5 of valve core of needle valve pinion rotation situation, and be arranged at needle valve body one end and the signal sent for received bit displacement sensor and and upper machine communication, and control the controller of actuating motor work.
Wherein, described fuel tank to be positioned at below actuating motor and coupled.
Motor is driven by the oil that actuating motor is brought in fuel tank and rotates, and motor and valve core of needle valve gears meshing, so motor can drive valve core of needle valve pinion rotation.
Actuating motor is then for being transported in motor by fixing speed by the oil in fuel tank.
Particularly, described fuel tank is also provided with inhalation valve 7, this inhalation valve is specifically fixed on the ventilation plant on case top, with the normal state of pressing in guard box, prevents superpressure or ultravacuum in case from causing damage, also can reduce the loss that evaporates.
Particularly, between described motor with valve core of needle valve gear, manually clutch 8 is connected; Described valve core of needle valve gear is also coaxially connected with handwheel 9.One place of manual clutch connects with on valve core of needle valve gear, and engages with it; Another place and motors, and be connected for coaxial with motor; When needs control valve core of needle valve rotation automatically, only manual clutch need be closed.But the object arranging handwheel realizes hand rotation valve core of needle valve, particular by unclamping manual clutch, making motor cannot drive valve core of needle valve pinion rotation, then manual rotation handwheel, can realize rotating valve core of needle valve.
Particularly, institute's displacement sensors is arranged at on the gear shaft of valve core of needle valve gears meshing.By arranging gear shaft, when valve core of needle valve rotates, inevitable driven gear axle rotates, and so just detects by displacement transducer the angle that valve core of needle valve rotates.
Preferred as one, controller is provided with RS232 interface.By arranging RS232 interface, controller can carry out communication with upper-position unit.
The utility model automatic control flow chart: long-range send action authorized order after, the control signal that the synchronous Real-time Collection of controller is long-range to be sent and 0 ~ 5V valve position signal that displacement transducer transmits, compare and algorithm in controller inside, control command is exported in actuating motor plate by RS232 interface, actuating motor plate finally exports the driving power of actuating motor, drive actuating motor action, produce hydraulic flow, control motor action, and by displacement transducer forming position closed loop, finally make valve position be in settling position.
Local regulable control process is substantially the same, and just local control signal is produced by controller inside.
Non-follow control flow process: manual clutch is totally released, now the gear of motor will depart from valve core of needle valve gear, valve core of needle valve gear and handwheel are directly be connected (and coaxial), as long as rotate handwheel and rotatable valve core of needle valve gear, and then pin valve opening in mobile valve.
What deserves to be explained is, the utility model has the execution architecture of automatic adjustment, monitoring automatically, can accept PC control, perform corresponding action, feed back signal to upper-position unit simultaneously.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical problem; even if some making on the utility model are without substantial change or polishing; the essence of the technological scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
