Description
Technical field
This utility model relates to the Quick Connect Kit of a kind of fracture well head and pipeline, in particulars relate to one and 140MPa pressure
The line connection device of above well head pipeline fast sealing and needs often dismounting.
Background technology
Union is a kind of conduit coupling facilitating installing/dismounting, is widely used in acid process environment, mainly at discharge pipe, defeated
Enter during pipeline, temporary fluid pipeline and fracture well head are connected with the pipeline of fracturing unit truck conveyance fluid use, can motionless pipe and incite somebody to action
Two pipes are separately.At present, the sealing of known union be outer power be tightened onto make the most afterwards end-face seal ring tighten generation seal
Effect, needs to pound tightly with hammer during routine use, but speedily carries out rescue work scene in blowout, due to full natural gas, it is impossible to make
Pounding union with hammer, in order to avoid causing spark to cause the accident expansion, the connection causing pipeline is the most difficult；Further, at high-voltage tube
When using on line, union material and sealing member are easily deformed causing seepage.
Utility model content
The purpose of this utility model is to provide a kind of fracture well head and quickly connects union, and its installation is more convenient, sealing effectiveness more preferable,
And can thoroughly avoid hammer to produce spark during pounding tightly, installation process is safer.
To achieve these goals, technical solution of the present utility model is:
A kind of fracture well head quickly connects union, including the first crossover flange, the second crossover flange, described first crossover flange
Connect end outer wall and be provided with external screw thread, described second crossover flange connect small outer diameter section that end includes being arranged in order from top to bottom, in
External diameter section and big outer diameter section, form the first positioning step between described small outer diameter section and middle external diameter section, in described middle external diameter section and
Forming the second positioning step between big outer diameter section, described small outer diameter section outer wall has seal groove, is provided with sealing in described seal groove
Circle, the connection end of described first crossover flange is enclosed within described small outer diameter section and the connection end end of described first crossover flange is supported
Leaning against on described first positioning step, described middle external diameter section outer wall is provided with external screw thread, and described middle external diameter section external screw thread connects locking
Nut, the connection end external screw thread of described locking nut and described first crossover flange connects locking cap.
This utility model fracture well head quickly connects union, wherein, described locking cap has radial direction through hole, described radial direction through hole
Inside it is used for inserting check lock lever.
This utility model fracture well head quickly connects union, and wherein, described locking nut is anti-tooth locking nut, and described anti-tooth is locked
Jack panel female thread have employed anti-tooth trapezoidal thread.
This utility model fracture well head quickly connects union, wherein, forms second fixed between described middle external diameter section and big outer diameter section
Position step, described locking nut lower end is resisted against on described second positioning step.
After using such scheme, compared with prior art quickly connect union the second crossover flange due to this utility model fracture well head
Small outer diameter section outer wall have seal groove, be provided with sealing ring in seal groove, the connection end of the first crossover flange is enclosed within the second conversion
On the small outer diameter section of flange, and the connection end external screw thread connection of the second crossover flange, the first crossover flange has locking cap, therefore
Only sealing ring and the first crossover flange connection end inwall need to be made mutually to compress and can realize sealing, installation side by screwing locking cap
Just, can thoroughly avoid hammer to produce spark during pounding tightly, installation process is safer, it is to avoid occur installing in prior art
With the leakage phenomenon produced because producing axial force height pressure reduction when end-face seal ring seals during use.
Accompanying drawing explanation
Fig. 1 is the partial sectional view that this utility model fracture well head quickly connects union.
Detailed description of the invention
As it is shown in figure 1, this utility model one fracture well head quickly connects union, change including the first crossover flange 11, second
Flange 12, the connection end outer wall of the first crossover flange 11 is provided with external screw thread, the connection end of the second crossover flange 12 include to
Under the small outer diameter section 121, middle external diameter section 122 and the big outer diameter section 123 that are arranged in order, in small outer diameter section 121 and middle external diameter section 122
Between form the first positioning step, between middle external diameter section 122 and big outer diameter section 123, form the second positioning step, small outer diameter section
121 outer walls have twice annular seal pocket, are provided with sealing ring 13, the company of the first crossover flange 11 in twice annular seal pocket
Connect end to be enclosed within small outer diameter section 121 and the connection end end of the first crossover flange 11 is resisted against on the first positioning step, middle external diameter
Section 122 outer walls are provided with external screw thread, and middle external diameter section 122 external screw thread connects has locking nut 14, locking nut 14 lower end to be resisted against
On second positioning step, the connection end external screw thread of locking nut 14 and the first crossover flange 11 connects locking cap 15.
This utility model fracture well head quickly connects union when using, and is connected with underwater flange by the first crossover flange 11, by the
Two crossover flanges 12 are connected with wellhead flange, then by screwing locking cap 15, make sealing ring 13 and the first crossover flange 11
Connect end inwall and mutually compress realization sealing.
It addition, more convenient during in order to screw locking cap 15, locking cap 15 has radial direction through hole 151, in radial direction through hole 151
For inserting check lock lever 16, only need to check lock lever 16 be inserted in radial direction through hole 151 during installation, manually pull locking cap 15
Produce high pressure sealing, so thoroughly avoid use hammer to pound situation that union cap causes spark to cause the accident occurs.
Further, locking nut 14 is anti-tooth locking nut, and anti-tooth locking nut female thread have employed anti-tooth trapezoidal thread, is using
Time locking nut 14 and locking cap 15 produce contrary direction force, it is ensured that during screwing locking cap 15, locking nut
14 do not have loosening.
Embodiment described above is only to be described preferred implementation of the present utility model, not to model of the present utility model
Enclosing and be defined, on the premise of without departing from this utility model design spirit, this area ordinary skill technical staff is new to this practicality
Various deformation that the technical scheme of type is made and improvement, all should fall in the protection domain that claims of the present utility model determine.
