Abstract
A kind of intelligent control throttle valve.It is by valve body 1, entry end 1-1, outlet end 1-2, throttling valve core 2, throttle orifice 3, limiting stopper 4, spur rack 5, restraining groove 6, end cap 7, stepper motor 8, gear 9, metering mechanism 10 and controller 11 form, valve body 1 is logical structure in T-shaped annulus, a throttling valve core 2 is provided with in valve body 1 upper end, throttling valve core 2 is mutually sealed and matched with the passage in valve body 1 and can moves up and down, the one side of throttling valve core 2 aligned inlet end 1-1 is provided with some throttle orifices 3, throttling valve core 2 is connected with spur rack 5, the side of spur rack 5 has restraining groove 6, two limiting stoppers 4 are provided with in valve body 1, limiting stopper 4 coordinates with the restraining groove 6 of spur rack 5, spur rack 5 is driven by a gear 9 and moves up and down, and gear 9, by stepper motor 8 driven rotary of a band auto-lock function, is provided with an end cap 7 outside the valve body 1 of spur rack 5 end, the outlet end 1-2 of valve body 1 is provided with a metering mechanism 10, metering mechanism 10 is connected with controller 11, and controller 11 is connected with stepper motor 8, and the utility model can improve the negotiability of throttle valve, block fluid capacity and flow control accuracy.
Description
Technical field
The utility model relates to the throttle valve accurately controlled for Oil/gas Well pressure.
Background technique
In existing oil, natural gas extraction operation, the fluid that pressure imbalance due to down-hole needs throttle valve to return out to control well head, back pressure value is controlled in rational scope, because the pressure of down-hole changes over time, make the flow of throttle valve need to regulate according to the change of pressure, need often to carry out manual tune.
Summary of the invention
Precisely cannot control the deficiency of flow in order to solve existing throttle valve for a long time, the utility model provides a kind of increases the negotiability of throttle valve, block the intelligent control throttle valve of fluid capacity and flow control accuracy.
The utility model solves the technological scheme that its technical problem adopts: the valve body of intelligent control throttle valve is logical structure in T-shaped annulus, a throttling valve core is provided with in described valve body upper end, passage in described throttling valve core and valve body is mutually sealed and matched and can moves up and down, the throttling valve core of described entry end is provided with some throttle orifices, described throttling valve core is connected with a spur rack, the side of described spur rack has restraining groove, at least two limiting stoppers are provided with in described valve body, described limiting stopper coordinates with the restraining groove of spur rack, described spur rack is moved up and down by a gear driven, described gear is by the stepper motor driven rotary of a band auto-lock function, an end cap is provided with outside the valve body of described spur rack end, the hole moved up and down for spur rack is had in described end cap, the outlet end of described valve body is provided with a metering mechanism, described metering mechanism is connected with controller, described controller is connected with stepper motor.
The number that flowmeter detects the liquid flow through in throttle valve is detected by controller, control step motor driven gear rotates and drives spur rack to move up and down, the moving up and down of spur rack drive the Exposure of throttle orifice in throttling valve core and valve body inlet end number to adjust the flow of throttle valve, limiting stopper can limit the position of spur rack, do not allow it move everywhere, the stepper motor of band auto-lock function can firmly pin spur rack and not move.
The beneficial effects of the utility model are: the utility model can improve throttle valve negotiability, block fluid capacity and flow control accuracy.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
