Preferably, the upper surface of the positioning threads ring is equipped with 4 holes, is fixed on the upper flange with 4 bolts.
The present invention, which allows, upper flange while to be met normal production and being put into what speed column was produced after carrying out fracturing work
General utility functions, and reduce the height of total equipment, reduce the risk of operation field.
Detailed description of the invention
Fig. 1 is design scheme structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram of positioning threads ring.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Closing the drawings and specific embodiments, the present invention will be further described in detail, the range of but do not limit the invention in any way.
As shown in Fig. 1, pressing sleeve (2) are arranged in the two sides of the bottom of upper flange (1), to rotate upper flange (1).Jackscrew (4)
Two sides in upper flange (1) are set, first end radially across upper flange (1) lateral wall, into the inner cavity of upper flange (1).
Pass through the convex block company of fixation mutually chimeric with the U-lag of wedge block rear end of jackscrew front end between the jackscrew (4) and wedge block (3)
It connects.Second face of wedge block (3) is provided with step, and the contact surface of the step and speed column is inclined-plane.The jackscrew drives
The wedge block (3) does stretching in the inner cavity of upper flange (1) or retracts movement.
Positioning threads ring (5) is fixed on inside the annular notch of upper flange (1) inner cavity top setting；The positioning threads ring
(5) top with it is continuous at the top of upper flange (1), flushed on the inside of positioning threads ring (5) with the upper flange (1) inner cavity and continuously；Institute
It states positioning threads ring (5) bottom and is provided with step, be in contact with the step of the wedge block (3), to limit the wedge block (3)
Moving range.As shown in Fig. 2, the upper surface of the positioning threads ring (5) is equipped with 4 holes, is fixed on 4 bolts described
Upper flange (1).
Main valve (6) and raising flange (7) one reinstate the top that stay bolt is fixedly installed in the upper flange (1).Raising method
The first end of blue jackscrew (8) passes through the lateral wall for increasing flange (7), into the inner cavity for increasing flange (7), to withstand speed
Tubing string.
When the jackscrew (4) drives wedge block (3) to stretch out the inner cavity of upper flange (1), the step of wedge block (3) supports upper method
The speed column being arranged inside blue (1) inner cavity；When the jackscrew (4) drives wedge block (3) to retract the inner cavity of upper flange (1), make
Obtain the inner cavity that BPV passes through upper flange (1).
Since the device is needed for pressure break process, fracturing process, which can generate inner cavity, to be washed away, and the meeting in fracturing process
Take the silt of underground to upper flange inner cavity wedge block slot part；Therefore upper flange (1) the inner cavity built-up welding 625 in the present invention
Alloy, and when the wedge block (3) retracts upper flange (1) inner cavity with cleaning hole is opened up at lumen contact, to clean in pressure break mistake
The silt generated in journey.
