The deficiency of above-mentioned prior art, it can effectively solve the scene of under balance pressure drilling in the prior art liquid-gas separator, U-tube and install and make
Industry there is a problem of wasting time and energy, efficiency of construction is relatively low, there is potential safety hazard.
One of technical scheme is realized by following measures：A kind of underbalance Special rotary flange, bag
Upper flange and lower flange are included, the integral middle of the upper flange is fixedly connected with level board, and the top one of lower flange is fixed
Lower horizontal board is connected with, bearing is provided between the upper level board and lower horizontal board, the bearing includes bearing outer ring and bearing
Inner ring, bearing outer ring is fixed together with upper level board, and bearing inner race is fixed together with lower horizontal board.
Here is the further optimization and/or improvements to foregoing invention technical scheme：
Sealing ring can be provided between the bottom of above-mentioned upper flange and the top of lower flange.
Above-mentioned sealing ring can be O-ring seal.
Above-mentioned bearing can be single roller bearing.
Bearing outer ring described above can be fixed together with upper level board by bolt, the bearing inner race with
Lower horizontal board can be fixed together by bolt.
The two of technical scheme are realized by following measures：A kind of underbalance Special rotary flange connection
Device, including underbalance Special rotary flange, U-tube and liquid-gas separator, the upper flange are fixedly mounted on one with U-tube
Rise, the lower flange is fixedly installed togather with liquid-gas separator.
Reasonable and compact in structure of the present invention, it is easy to use, it is after liquid-gas separator is fixed in well site position, underbalance is special
Liquid-gas separator discharging tube is arranged on rotary flange to export and U-tube between, after installation is connected, if U-tube goes out
Mouth can not enter in elevated trough, it is only necessary to rotate U-tube outlet, i.e., U-tube reaches with underbalance Special rotary flange rotary
Adjustment U-tube outlet orientation target, realizes that disposable successfully outlet U-tube enters in elevated trough, is effectively saved installation and makees
The industry time, reduce work high above the ground risk.
Brief description of the drawings
Accompanying drawing 1 is the main view half section structural representation of the embodiment of the present invention 1.
Coding in accompanying drawing is respectively：1 is upper flange, and 2 is lower flange, and 3 is upper level board, and 4 is lower horizontal board, and 5 is axle
Bearing outer-ring, 6 is bearing inner race, and 7 is O-ring seal, and 8 is single roller bearing, and 9 is bolt.
Specific embodiment
The present invention is not limited by following embodiments, can technology according to the present invention scheme and actual conditions determine specifically
Implementation method.
In the present invention, for the ease of description, the description of the relative position relation of each part is according to Figure of description 1
Butut mode be described, such as：The position relationship of forward and backward, upper and lower, left and right etc. is according to the Butut of Figure of description
Direction determines.
With reference to embodiment and accompanying drawing, the invention will be further described：
Embodiment 1：As shown in Figure 1, the underbalance Special rotary flange includes upper flange 1 and lower flange 2, the upper flange 1
Integral middle be fixedly connected with level board 3, the top of lower flange 2 is integrally fixedly connected with lower horizontal board 4, the upper level
Bearing is provided between plate 3 and lower horizontal board 4, the bearing includes bearing outer ring 5 and bearing inner race 6, bearing outer ring 5 and upper level
Plate 3 is fixed together, and bearing inner race 6 is fixed together with lower horizontal board 4.Optimization length of the invention is 500mm, size specification
Including 4 〞, 6 〞, tri- kinds of 8 〞, the specification of underbalance Special rotary flange is performed fully according to API standard.The present invention it is rational in infrastructure and
It is compact, it is easy to use, after liquid-gas separator is fixed in well site position, by underbalance Special rotary flange be arranged on liquid qi leel from
Device discharging tube is exported and U-tube between, after installation is connected, if U-tube outlet can not enter in elevated trough, it is only necessary to
U-tube outlet is rotated, i.e. U-tube reaches adjustment U-tube outlet orientation target with underbalance Special rotary flange rotary, real
It is now disposable successfully to enter in elevated trough U-tube outlet, the installation exercise time is effectively saved, reduce work high above the ground wind
