Abstract
The utility model relates to a certain proportion ash valve used in cementing cement slurry mixing system equipment which can automatically control the slurry density, comprising a valve body, inside which a channel for transporting dry cement ash is arranged. The utility model aims to ensure the constant of the dry ash flow, characterized in that the channel is provided with valve flap to adjust the over flow cut area therein, the power source drives the valve flap to rotate by the rotating shaft, the rotating shaft is fixedly connected with an angular displacement sensor connected with the computer and the computer is connected with the power source via a hydraulic buttery valve or a relay.
Description
Technical field
The utility model relates to a kind of ratio ash discharging valve, is used for the mixing well cementing cement slurry equipment that cement slurry density can be controlled automatically.
Background technique
In the ocean or land well cementing operation of petroleum production industry, need to adopt cement slurry cementing equipment, this equipment should be able to be by setting that density is come mix cement slurry and with it continuously under the input well.And will realize that the automatic control of cement slurry density, one of its key are that can be according to setting density, and with reference to the flow of water flow control solid carbon dioxide plaster in pipeline.Existing ash discharging valve comprises valve body, has the passage of carrying the solid carbon dioxide plaster in the valve body, and what have then is provided with manual butterfly valve on pipeline.Problem is when fluctuation appears in the dry ash flow, promptly can directly influence cement slurry density, and obvious existing technical scheme is difficult to coupled computer works together, promptly in time regulates the dry ash flow in the ratio of water.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of ratio ash discharging valve, and its structure is fit to be controlled by computer, can in time regulate the dry ash flow when the dry ash flowed fluctuation.
The technological scheme that solves this technical problem is when comprising aforementioned formation, its unique distinction is: be provided with in the passage of carrying the solid carbon dioxide plaster and regulate the long-pending flap of passage overflow section, power source drives flap through rotating shaft and rotates, be fixed with the angular displacement sensor that links to each other with computer in the rotating shaft, computer links to each other with power source through hydraulic buttery valve or relay.
The technical program advantage compared to existing technology is: when fluctuation appears in the dry ash flow, computer passes through angular displacement sensor, identification flap present located position, and according to water flow and default cement slurry density value, instruction drive power source flap is opened big or is turned down flow channels, promptly regulate the dry ash flow, thereby make constant flow by changing the long-pending size of overflow section.Because the angular displacement and the dry ash flow of flap are linear, the easier realization of the technical program is controlled automatically again.
Description of drawings
Fig. 1 is the integrally-built sectional view of reflection the utility model.
Fig. 2 is the sectional view of flap rotating assembly.
Fig. 3 is the partial view of another kind of mode of execution.
Embodiment
With reference to Fig. 1~Fig. 3, the technical program comprises valve body 1, has the passage 9 of carrying the solid carbon dioxide plaster in the valve body 1, in order to keep the dry ash constant flow, in this passage 9, be provided with and regulate the long-pending flap 2 of passage 9 overflow sections, power source 7 drives flap 2 through rotating shaft 3 and rotates, and is fixed with the angular displacement sensor 6 that links to each other with computer 8 in the rotating shaft 3, and computer 8 links to each other with power source 7 through hydraulic buttery valve 10 or relay 11.
The utility model further technological scheme is: when power source 7 during for hydraulic jack 7 ', this oil cylinder 7 ' drives rotating shaft 3 through pinion and rack 5, be connected with the dial 4 that shows flap 2 angular displacements in the rotating shaft 3, computer 8 links to each other with oil cylinder 7 ' through hydraulic buttery valve 10.Described hydraulic buttery valve 10 can adopt the two-position four-way hydraulic buttery valve.
Further technological scheme can also be: when power source 7 is motor 7 " when (stepper motor or actuating motor), 8 in computer is through relay 11 and motor 7 " connect, be connected with the dial 4 that shows flap 2 angular displacements in the rotating shaft 3.This dial 4 is used for artificial auxiliary the sight and looks into flap 2 angular displacements.
Wherein, computer 8 and hydraulic buttery valve 10 or computer 8 and relay 11 and motor 7 ", perhaps computer 8 all is a prior art with angular displacement driver 6 more detailed electrical connections, specifically can be referring to " mechanical engineering manual " the 6th volume, the 35th and 37 piece.
