Abstract
A kind of combination type oil well production tree big four.Mainly solve existing big four processing difficulties, the problem that processing cost is high.It is characterized in that: on upper flange body (1) and lower flange body (2), axially have bolt hole, there is ring gasket groove upper flange body (1) upper surface and lower flange body (2) lower surface, clip short circuit (3) external end head has hoop, there is conic tube upper flange body (1) lower end, there is main seam cylinder lower end, there is conic tube lower flange body (2) upper end, in cylinder upper end is placed in main seam and by being welded and fixed, upper flange body (1) has side seam with both sides outside lower flange body (2) junction, in clip short circuit (3) inner termination is placed in side seam and by being welded and fixed.This combination type oil well production tree big four has handling ease, the feature that processing cost is low.
Description
Technical field
This utility model relates to the big four used by a kind of oil field shaft mouth production tree, and especially combination type oil well production tree is big
Four-way.
Background technology
Field of oil field oil extraction, oil well are provided with production tree.Production tree is by lower flange, big four, upper flange, little by four
Logical, 250 valves, test strobe and packing box composition.And there is processing difficulties due to reasons in structure in existing big four, processing cost
High problem, is unfavorable for popularization and application.
Summary of the invention
In order to solve existing big four processing difficulties, the problem that processing cost is high.This utility model provides a kind of combination type
Oil well production tree big four.This combination type oil well production tree big four has handling ease, the feature that processing cost is low.
The technical solution of the utility model is: this combination type oil well production tree big four includes upper flange body, lower flange body
And clip short circuit.Bolt hole, upper flange body upper surface and lower flange body lower surface is axially had on upper flange body and lower flange body
Ring gasket groove, clip short circuit external end head is had to have hoop, upper flange body lower end to have conic tube, cylinder lower end to have main seam,
In lower flange body upper end has conic tube, cylinder upper end to be placed in main seam and by being welded and fixed, upper flange body and lower flange body
In outside junction, both sides have side seam, clip short circuit inner termination to be placed in side seam and by being welded and fixed.
This utility model have the advantages that this combination type oil well production tree big four due to use upper flange body and
Bolt hole, upper flange body upper surface and lower flange body lower surface is axially had to have ring gasket groove, outside clip short circuit on lower flange body
Termination has hoop, upper flange body lower end to have conic tube, cylinder lower end to have main seam, lower flange body upper end to have conic tube,
In cylinder upper end is placed in main seam and by being welded and fixed, upper flange body has side seam with both sides outside lower flange body junction, card
In hoop short circuit inner termination is placed in side seam and by the structure being welded and fixed.Utilize upper flange body, lower flange body and clip short
Connecing and be combined into big four, and then make handling ease, processing cost reduces, and simple in construction.This combination type oil well is adopted thus
Oil tree big four has handling ease, the feature that processing cost is low.
Accompanying drawing illustrates:
Accompanying drawing 1 is this utility model structural representation.
1-upper flange body in figure, 2-lower flange body, 3-clip short circuit.
Detailed description of the invention:
The utility model is described in further detail below in conjunction with the accompanying drawings:
Shown in accompanying drawing, this combination type oil well production tree big four includes that upper flange body 1, lower flange body 2 and clip are short
Connect 3.Bolt hole, upper flange body 1 upper surface and lower flange body 2 lower end is axially had on forging upper flange body 1 and forging lower flange body 2
Face has ring gasket groove, forging clip short circuit 3 external end head to have hoop, upper flange body 1 lower end to have conic tube, cylinder lower end to have
Main seam, lower flange body 2 upper end has conic tube, cylinder upper end to be placed in main seam and by being welded and fixed, upper flange body 1 with
In outside lower flange body 2 junction, both sides have side seam, clip short circuit 3 inner termination to be placed in side seam and by being welded and fixed.Due to
Use forging upper flange body 1, lower flange body 2 and clip short circuit 3 big by CO 2 gas-shielded automatic round welder
Four-way, uses junior machine to process, thus makes big four handling ease, and processing cost is low.Simultaneously as on employing forging
Flange body 1, lower flange body 2 and clip short circuit 3, occur that sand holes and crackle are few, thus waste product be the fewest, final processing cost drops
Low.Existing big four generally uses casting to hold stove mode and casts, and its product is easily generated deformation burning into sand, pore, and casting density is low, holds
The defects such as pressure energy power is poor, and finished product rate is low.This combination type oil well production tree big four simple in construction, intensity is big, processability
Can be good, stable performance, outward appearance is beautiful, and service life is long, reduces leakage and the pollution to environment, extends 30% service life..
