As by fracturing device, liquid dispensing device, support agent storage device, liquid storaging device, manifold etc. to constitute, in pressing crack construction, match somebody with somebody
The good fracturing fluid of mixture is conveyed to fracturing device by feed flow manifold with certain pressure by liquid device, after being pressurized by fracturing device
In injection Oil/gas Well.In whole work flow, feed flow manifold serves the effect for conveying fracturing fluid to fracturing device.According to not
Require with operation technique, operational discharge capacity often has very big difference, and the displacement range of liquid dispensing device is also different, typically requires in Q
Between～10Q.Accordingly, as the feed flow manifold for conveying liquid between liquid dispensing device and fracturing device, it is desirable to Q can be met simultaneously
To 10Q, any discharge capacity carries out liquid conveying, and the pressure value for ensureing to reach job requirements in pipeline.
At present, the feed pipe Correspondent in land and ocean platform fracturing work is pressed according to scene frequently with 4 cun of rubber hose
Job requirements are split, connects many 4 cun of rubber hose between liquid dispensing device and fracturing device, by controlling the unlatching of butterfly valve, changed
Become the quantity of 4 cun of connected rubber hose, to adapt to the conveying of different flow fracturing fluid, it is ensured that the suction side of fracturing device has
Sufficient suction pressure.
Existing feed flow manifold is applied has problems with pressure break ship：1 is limited by the space of hull and cabin, is not had
The existing pipeline of enough space mountings is completing the conveying of fracturing fluid；2 single 4 cun of rubber hose cannot meet different displacements pressure
Split liquid conveying to require.So, the feed liquid way adopted by current land is not applied for pressure break ship.
Content of the invention
The purpose of this utility model is to provide a kind of pressure break ship feed flow manifold, disclosure satisfy that ship installing space and pressure break are made
Industry process requirements, it is ensured that the suction pressure of fracturing device.
For achieving the above object, the technical solution of the utility model is：
A kind of pressure break ship feed flow manifold, including manifold 1, butterfly valve I 2, butterfly valve II 3, supervisor 4, arm 5, it is characterised in that：Discrimination
Pipe 1 has two branch roads, arranges in Ч types, and 4 caliber of supervisor of two branch roads is not equal to the caliber of arm 5, has between two branch roads
One angle a.
The supervisor 4 is made up of I 4-1 of flange connecting pipe, I 4-2 of bending rubber joint, and I 4-2 of bending rubber joint connects
On I 4-1 of flange connecting pipe.
Arm 5 includes that II 5-1 of flange connecting pipe, II 5-2 of bending rubber joint, II 5-2 of bending rubber joint are connected to
On II 5-1 of flange connecting pipe.
I 4-1 of flange connecting pipe, II 5-1 of flange connecting pipe have at least four branch roads respectively, I 4-2 of bending rubber joint and can be bent
II 5-2 of torsion rubber joint is connected on I 4-1 of flange connecting pipe, each branch road of II 5-1 of flange connecting pipe.
The beneficial effects of the utility model are：
The utility model devises the manifold structure of two kinds of calibers：In small displacement fracturing work, using the pipe of pipe with small pipe diameter
Remittance ensures the suction pressure of fracturing device；In huge discharge fracturing work, ensure the suction of fracturing device using the manifold of Large Diameter Pipeline
Enter pressure and equipment safety operation.Bending rubber joint is mounted on the branch road of the utility model manifold, confession can be absorbed
The vibration produced during liquid pipe remittance work, it is to avoid the destruction that vibration is caused to feed flow manifold, it is ensured that fracturing work safe and reliable operation.
There are at least four branch roads on the manifold of two kinds of calibers of the utility model, at least four fracturing device feed flows can be given simultaneously.

Specific embodiment
1-4 further illustrates specific embodiment of the present utility model below in conjunction with the accompanying drawings.
Referring to Fig. 1 and 4：A kind of pressure break ship feed flow manifold, including manifold 1, butterfly valve I 2, butterfly valve II 3, supervisor 4, arm 5, discrimination
Pipe 1 has two branch roads, arranges in Ч types, and the caliber of two branch roads differs, and between two branch roads, angle is a, one of manifold 1
Road is connected by butterfly valve I 2 and supervisor 4, and another branch road of manifold 1 is connected with arm 5 by butterfly valve II 3, wherein, supervisor's 4
Caliber is not equal to the caliber of arm 5, selects two branch roads wherein by the switch of control butterfly valve I and butterfly valve II.
Referring to such as Fig. 2, Fig. 3, the supervisor 4 is made up of flange connecting pipe I (4-1), bending rubber joint I (4-2)；Described
Arm 5 is made up of flange connecting pipe II (5-1), bending rubber joint II (5-2), flange connecting pipe I (4-1), II (5- of flange connecting pipe
1) there are at least four branch roads.In supervisor and arm, bending rubber joint is separately mounted to flange connecting pipe I and flange connecting pipe
On II every branch road, bending rubber joint is used for the vibrations for absorbing manifold.
During huge discharge fracturing work, the butterfly valve I (2) on supervisor 4 is opened, and the butterfly valve II (3) on arm 5 cuts out, fracturing fluid
Fracturing device low-pressure manifold is entered by least four branch roads being responsible for；Butterfly valve II during small displacement fracturing work, on arm 5
(3) open, the butterfly valve I (2) on supervisor 4 cuts out, fracturing fluid enters fracturing device low-voltage tube by least four branch roads of arm
Converge.
There is following relation in caliber, pressure and flow：
P=Q²*ρgSL
S=10.3n^2 / D^5.33
D-- internal diameter of the pipeline；N-- inner-walls of duct roughness；S-- resistivitys；L-- duct lengths；ρ -- fracturing fluid density；
Q-- flows；P-- pressure reduction
From above formula, when the suction pressure of fracturing pump is certain certain value, same fracturing fluid identical pipe material,
Under identical duct length during operation, when flow becomes hour, caliber also accordingly diminishes.
The fracturing unit feed flow manifold can adapt to large and small discharge capacity fracturing work work on the premise of liquid supply pressure is ensured
Condition, by 4 feed flow of supervisor of Large Diameter Pipeline during huge discharge operation, by 5 feed flow of arm of pipe with small pipe diameter during small displacement operation.
