Show, more preferably, between the first continuous curve surface 104 and the tangent line and axis 5 of the intersection of the first pipe end 102
The first angle 6 can be 18 °, the tangent line of the second continuous curve surface 105 and the intersection of the second pipe end 103
The second angle 7 between axis 5 can also be 18 °.Oily drilling rod is allowd in non-snubbing service
Scene under, it is easy to by the rotary blowout preventer glue core being arranged on casing head of well head.
Alternatively, the first continuous curve surface 104 and the second pipe end 103 and the Tensile of the second continuous curve surface 105
When the factor of stress concentration be 1.21.
Alternatively, the axial length of the first continuous curve surface 104 and the second continuous curve surface 105 can be 100
Millimeter.
It should be noted that the axial length of the first continuous curve surface 104 and the second continuous curve surface 105 is set
100 millimeters are set to so that body 101 forms the first continuous song by needing only to a time hot extrusion jumping-up
The continuous curve surface 105 of face 104 and second, manufacturing process is simple.If the first continuous curve surface 104 and second
If the axial length of continuous curve surface 105 is long, then multi-pass hot extrusion jumping-up is needed to form first
The continuous curve surface 105 of continuous curve surface 104 and second.
In another embodiment, the first pipe end 102 and the first port 201 of the first joint of body 1 are welded
Connection；Second pipe end 103 of body 1 is welded to connect with the first port 201 of the second joint.
More specifically, the friction welding of first port 201 of the first pipe end 102 of body 1 and the first joint
Connection；Second pipe end 103 of body 1 is connected with the friction welding of first port 201 of the second joint.
It should be noted that the first pipe end 102 of body 1 passes through with the first port 201 of the first joint
Friction welding connects so that between first pipe end 102 and the first port 201 of the first joint of body 1
Friction welding seam 4 is formed, likewise, second pipe end 103 and the first port 201 of the second joint of body 1
Between also form friction welding seam 4.
Preferably, the first joint 2 and the first pipe end 102 and the second joint 3 and the second pipe end 103 it
Between friction welding condition it is as follows：Friction pressure is 60-75MPa, fraction time 10-12sec, upset pressure
Power 110-130MPa.Friction welding is carried out under the conditions of being somebody's turn to do can ensure that the first joint 2 and the first pipe end 102
And second friction welding between joint 3 and the second pipe end 103 quality, while friction can also be reduced
The cost of welding.
Preferably, the first pipe end 102 of body 1 and the first port 201 of the first joint adopt external upset (EU)
Friction welding connects；Second pipe end 103 of body 1 is with the first port 201 of the second joint using additional
Thick friction welding connection so that the first pipe end 102 of body 1 and the first port 201 of the first joint it
Between the thickness of friction welding seam 4 increase, likewise, the second pipe end 103 of body 1 and the second joint
The thickness of the friction welding seam 4 between first port 201 also increases.
In another embodiment, alternatively, first pipe end 102 and the first port of the first joint of body 1
The sectional area of 201 end face is 1.72 times of the sectional area of body 101, likewise, the second of body 1
The sectional area of the end face of the first port 201 of the joint of pipe end 103 and second is the sectional area of body 101
1.72 again.As such, it is possible to advantageously account for friction welding seam semi-finals degree and toughness is below a difficult problem for mother metal,
Joint being it also avoid simultaneously and differing too big with pipe diameter, easily injury is arranged on the rotation on casing head of well head
The problem of rubber core of lubricator.
It should be noted that above-mentioned rotating blowout preventer rubber core is in oil drilling, installed in casing head of well head
On, for controlling the blowout apparatus of hydraulic oil, gas and water, when OIH atmospheric pressure is very high, rotation is anti-
Spray apparatus glue core can close well head, and when weighted mud is pressed into from oily drilling rod, rotating blowout preventer rubber core
Flashboard under have four-way, alternatively go out the mud by gas cut, increase the pressure of fluid column in well, to push down height
The ejection of force feed gas.
