Description
Technical field
This utility model relates to well head technical field of intelligence, is specifically related to a kind of intelligent Water injection well head device.
Background technology
Existing wellhead assembly is to be made up of traditional gate valve, oil pipe four-way and four-way junction of casing.Four-way junction of casing is mainly by hanging
Hanging device, four-way and upper flange are constituted, hanger connected pipes, adjust fixing by four jackscrews, and oil pipe four-way central part is two
90 ° of Intersect structures of cylinder, valve is all traditional structure, uses traditional flange to couple, and the shortcoming or the deficiency that exist be: 1. sleeve pipe
Processing top wire hole on four-way relatively difficult, complex operation, in the case of long-term high pressure water injection, screw thread easily corrodes, and causes jackscrew to grasp
Making difficulty, safety coefficient reduces simultaneously；2. hanger structure is complicated, and cost is high, and processing and aboveground operation are the most cumbersome；3. go up
Flange and four-way junction of casing steel ring seal, and processing request is tight, and aboveground task difficulty is big, and location difficulty, steel ring is easily damaged；4. well-head valve
Door all uses flange to couple, and cost is high, inconvenient operation；5. valve is easily stolen and tears open, repairs, and impact produces and also causes environment dirty
Dye, also buries potential safety hazard for producing in the future.This is accomplished by the setting of a kind of intelligent wellhead assembly, it is possible to good improvement is each
The problem of kind.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of simple in construction, and design is closed
Reason, the intelligent Water injection well head device of one easy to use, it uses and upper connecting tube side is provided with water injection pipe, passes through water injection pipe
On the cooperating of smart valve and pressure transducer, under controlling device effect, Based Intelligent Control water filling situation, prevent hydraulic pressure too high,
And it has easy to use, simple to operate, the features such as practicality is good, with low cost.
For achieving the above object, the technical solution adopted in the utility model is:
The intelligent Water injection well head device of one described in the utility model, including end pipe and upper connecting tube, pipe upper end, the described end
Being provided with upper connecting tube, be provided with inner sleeve and trocar sheath in the middle of pipe of the described end and upper connecting tube, described inner sleeve is coaxial with trocar sheath
Being connected, described upper connecting tube side is provided with water injection pipe, and described water injection pipe lower end is provided with pressure transducer, described pressure transducer
Being arranged on trocar sheath, described water injection pipe is provided with smart valve, described smart valve connects control device, described control device
It is connected with pressure transducer, in pipe of the described end, is provided with Intelligent three-way valve.
Smart valve front end in described water injection pipe is provided with water filling hands valve, and the setting of water filling hands valve can play Non-follow control
Effect, it is possible to play the effect that secondary ensures, belong to a kind of manual protection mechanism.
Using two to lead to nut between pipe of the described end and upper connecting tube to fix, described two lead to nut uses stainless steel material, uses
Two lead to nut connecting bottom tube and upper connecting tube, have good dismoutability, use stainless steel material simultaneously, have good connection effect
Fruit and good steadiness.
After using said structure, this utility model has the beneficial effect that this utility model, and it uses in the setting of upper connecting tube side
There is water injection pipe, by cooperating of the smart valve on water injection pipe and pressure transducer, under controlling device effect, Based Intelligent Control water filling
Situation, prevents hydraulic pressure too high；Employing can only the setting of three-way valve can switching between inner sleeve and trocar sheath, it is possible to ensure
The reasonable employment of inner and outer pipes；And it has easy to use, simple to operate, the features such as practicality is good, with low cost.
