Description

A kind of rotatable flange connecting apparatus and connection method
Technical field
The present invention relates to oil gas field construction operation fields, in particular to flange connecting apparatus.
Background technique
Flanged joint is usually used in oil-gas field fracturing construction and other high-pressure fluids conveying construction operation, conventional flange pipeline are Monoblock type, installation is more demanding to field ground flatness, installation dimension when connecting, and pipe center and two flange bolt holes must It entirely on the center must could connect and effectively seal.Since field condition limits, it is difficult to smoothly complete flange pipeline in more situation Be linked and packed, installation personnel labor intensity increase, it is time-consuming and laborious.The rotatable flange connecting apparatus of the type is designed, it can It solves the problems, such as to encounter when the installation of above-mentioned flange pipeline, satisfies the use demand, reduce installation difficulty.
Summary of the invention
The difficulty that it is an object of the invention to solve to encounter when the installation connection of conventional flange pipeline, provides a kind of new flange Attachment device and connection method, the present invention can during installation flange can Arbitrary Rotation, alignment is accurate, connection is quick.
To achieve the above object, the technical solution of the present invention is as follows:
A kind of rotatable flange connecting apparatus, it is characterised in that: including tube body, rotary flange, collar stop, threaded collar, Integral flange, one end of the tube body are connected with mounting flange, and annular groove, annular gear are provided on the tube body section of the other end Block is mounted in groove, and rotary flange is sleeved on tube body, and rotary flange inner ring is provided with boss, and boss is matched with collar stop It closes, rotary flange is prevented to be detached from tube body, rotary flange inner ring is provided with screw thread, and threaded collar outer circle and rotary flange pass through screw thread Connection, threaded collar one end is concordant with rotary flange, the other end and annular retaining ring clearance fit, be arranged on threaded collar end face etc. The hole of spacing distribution, is provided with bolt hole on rotary flange 2, and can rotate freely around 360 degree of body central line.
The collar stop is divided into multistage, and cross sectional shape can be equilateral polygon, is also possible to non-equilateral polygon Shape.
A kind of connection method of rotatable flange connecting apparatus, it is characterised in that: this method specific steps are as follows:
(1) assembling of device: the groove ends by rotary flange ring set in tube body, Xiang Guanti mounting flange direction sliding, until exposing The groove of tube body, then in a groove by collar stop installation, mobile rotary flange makes its inner ring raised head face and collar stop Contact, is horizontally arranged the flange apparatus, threaded collar is mounted on rotary flange inner ring, the two is connected through a screw thread;
(2) connection of device: after device is completed, mounting flange is connected with the flange of one end on pipeline to be connect first It connects, by the rotary flange end alignment of device to the flange on the connecting pipeline other end, rotates threaded collar and rotary flange, make it On hole be aligned with the hole on underwater flange, insertion bolt installation can be completed.
The beneficial effects of the present invention are:
The rotatable flange connecting apparatus structure is simple, and practicability is good, securely and reliably.When the installation connection of flange pipeline, tube body After upper fixed flange is fixed, rotary flange with other when connecting flange docks can Arbitrary Rotation, simple and quick is complete At flange bolt hole centering, bolt and nut is installed, improves flange pipeline installation joint efficiency, reduces personnel labor intensity. The technical solution can effectively solve conventional flange pipeline in-site installation connection when, because place limitation etc. reasons, flange bolt hole without Method is entirely on the center to lead to the difficult problem that can not even connect of connection.The rotatable flange connecting apparatus can be applied to oil gas field The connection of gas testing pressing crack construction flange pipeline can also be applied to the connection of other field high pressure flange class pipeline.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention;
Fig. 2 is the sectional view of Fig. 1.
Specific embodiment
Below with reference to the drawings and specific embodiments, the present invention is further explained.It should be understood that these embodiments are only used for Illustrating rather than will limit the scope of the invention.After the present invention has been read, those of ordinary skill in the art are not having Other examples obtained under the premise of creative work are made, protection scope of the present invention is belonged to.
Referring to attached drawing 1-2, the present invention provides a kind of rotatable flange connecting apparatus, including tube body 1, rotary flange 2, ring Shape block 3, threaded collar 4, mounting flange 5, one end of the tube body 1 are provided with mounting flange 1, the end face of 1 other end of tube body Upper setting fluted 6, collar stop 3 is mounted in groove 6.Collar stop 3 can be divided into multistage, and cross sectional shape can be Equilateral polygon is also possible to non-equilateral polygon, can be easily installed in this way.
Rotary flange 2 is sleeved on tube body and can slide along tube body, and 2 inner ring of rotary flange is provided with boss, boss face with Annular retaining ring 3 cooperates, and thus rotary flange 2 is limited on tube body 1;
Threaded collar 4 is connected through a screw thread with rotary flange 2, and rotary flange 2 can be rotated freely around 360 degree of center line, screw thread gear It is concordant with 2 outer end face of rotary flange to enclose 4 one end, the other end and 3 clearance fit of annular retaining ring;Setting etc. on 4 end face of threaded collar The hole of spacing distribution, is provided with bolt hole on rotary flange 2, can be connect with other flange-interfaces by bolt and nut.
The present invention in the specific implementation, first by 2 sets of the rotary flange groove ends in tube body 1,1 mounting flange 5 of Xiang Guanti Direction sliding, until exposing the groove of tube body 1, then in a groove by the installation of collar stop 3, mobile rotary flange 2 makes its inner ring Raised head face is contacted with collar stop 3, is horizontally arranged the flange apparatus, and threaded collar 4 is mounted on 2 inner ring of rotary flange, The two is connected through a screw thread;After device is completed, mounting flange 5 is connected with the flange of one end on pipeline to be connect first It connects, by the rotary flange end alignment of device to the flange on the connecting pipeline other end, rotates threaded collar 4 and rotary flange 2, make Hole thereon is aligned with the hole on underwater flange, and installation can be completed in insertion bolt.
