During work, high pressure pipe joint discharged by fracturing unit truck and the oscillation phenomenon of double loop pressure break high pressure pipe joint substantially weakens, and flow velocity is steady,
Discharge capacity is stable, and through periodic detection, each member internal walls antiscour effect is obvious, and spoilage is low, and service life improves, and meets construction need
Ask.
2nd, the utility model big orifice double loop pressure break high pressure pipe joint is applied widely, safe and reliable, and pressure break efficiency is high.
3rd, the utility model big orifice double loop pressure break high pressure pipe joint, 10 fracturing unit trucks can be connected in flank two ends, maximum
Operational discharge capacity 9.08m3/ min, liquid flows to choose at random.
Brief description
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the utility model big orifice double loop pressure break high pressure pipe joint.
Detailed description of the invention
In order to be more clearly understood from technical characteristic of the present utility model, purpose and effect, now compare accompanying drawing detailed
Detailed description of the invention of the present utility model is described.
As it is shown in figure 1, the utility model big orifice double loop pressure break high pressure pipe joint includes the 1st, the T-shaped threeway 2 of flank plug valve
With straight tube 3.The two ends of T-shaped threeway 2 connect straight tube 3 respectively, and the other end connects flank plug valve 1.By 12 T-shaped threeways 2
Be connected eight rigid straight pipe 3 with ten plug valves 1, straight tube 3 point of two row arranged, and two row's straight tubes 3 are at one end through T-shaped threeway
2 connect.
The straight tube 3 of main channel all selects 4 " rigid straight pipe 3, the big antiscour of discharge capacity, and flank branch road is selected and thickeied T-shaped threeway
2 and plug valve 1, improve anti-shearing stress intensity.In plug valve 1, latus rectum is 2 ", and connecting union specification is 3 ", at 15000psi etc.
Under level execution conditions, Peak Flow Rate, more than the highest discharge capacity of fracturing unit truck, meets construction requirement.T-shaped threeway 2 is connected with plug valve 1
Part be single channel, the part that T-shaped threeway 2 is connected with straight tube 3 is binary channels.Single channel union is connected as F type, and binary channels is left
Wing passage union is connected as M type, and right channel union is connected as F type.Single channel and twin-channel angle are 90 °, high-pressure fluid
It is collected to main channel through branch road, there is antiscour effect.Single channel is identical with the internal diameter of plug valve 1, and binary channels is interior with straight tube 3
Footpath is identical.
The concrete specifications and models of the T-shaped threeway 2 in the present embodiment are 3 " F × 4 " MF 1502, and in single channel, latus rectum is 2 ",
Union is connected as 3 " 1502 and detains, and left and right binary channels is consistent with 4 " straight tube 3 structures.By the structural analysis to conventional T-shaped threeway 2,
Find each side reason producing quality accident, structure optimization is carried out to weak part, changes single channel internal diameter into 2 ", integral wall
Thick increase, identical with plug valve 1 internal diameter of outer connection, eliminate reducing defect, increase shear strength.
Adjacent legs spacing is 2.1m, facilitates fracturing unit truck discharge pipe to be connected with beeline with manifold plug valve 1, the shortest
Distance, less than 1.0m, eliminates the resonance effects that fluid produces.The T-shaped threeway 2 in main channel, left and right is connected composition loop, eliminates
The turbulent phenomenon that high-velocity fluid produces, keeps manifold main channel flow velocity stable equilibrium.
Flank plug valve 1 uses independent base to support, and eliminates extraneous stress.Base is skid-mounted type base, and base uses
Rubber blanket is U-shaped fastens seat supports.Rubber blanket is 3mm canvas filler rubber.
Above in conjunction with accompanying drawing, embodiment of the present utility model is described, but on the utility model is not limited to
The detailed description of the invention stated, above-mentioned detailed description of the invention is only schematically, rather than restricted, this area common
Technical staff is under enlightenment of the present utility model, without departing from the utility model objective and scope of the claimed protection situation
Under, it may also be made that a lot of form, these belong within protection of the present utility model.
