Schematic diagram when Fig. 3 uses for inventive flow coalignment.
The each labelling of in figure is as follows:
1 regulation handle, 2 springs, 3 butt tubes, 4 edge face sealing members, 5 end caps, 6 pressure-sensitive diaphragms, 7 tee Ts, 8 pressure feedback
Pipe, 9 regulating parts, 10 lip rings, 11 regulating part guide blocks.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings, but the invention is not limited in following examples.
As shown in figure 1, the flow matches device being applied to the conveying of multiple-limb pipeline material providing for the present invention, it includes
Butt tube 3, regulating part 9, pressure-sensitive diaphragm 6, pressure feedback pipe 8, regulation handle 1 and spring 2.This regulating part 9 includes a body of rod
(in figure is not marked) and the double round end keies (in figure is not marked) being arranged on this body of rod, wherein this body of rod be cylindrical, its diameter with
The thickness of double round end keies is equal.As shown in Fig. 2 along butt tube 3 radially, butt tube 3 is tightly connected above-mentioned regulating part 9,
And this regulating part 9 can moving radially along butt tube 3.Regulating part 9 enters particular by edge face sealing member 4 and lip ring 10
Row sealing.The two ends of the body of rod all extend to outside the cavity of butt tube 3, and its one end is sequentially connected regulating part guide block 11, spring 2 and adjusts
Section handle 1；The outer wall of butt tube 3 and end cap 5 form cavity (in figure is not marked), and the other end edge of the body of rod extends in above-mentioned cavity
And be connected with the pressure-sensitive diaphragm 6 being arranged in this cavity, the cavity of the other end of pressure-sensitive diaphragm 6 is connected with pressure feedback pipe 8
Logical, the other end of this pressure feedback pipe 8 is connected with butt tube 3, to realize the perception to the pressure in butt tube 3 and feedback.
In the present invention, a tee T 7 is arranged on end cap 5, pressure feedback pipe 8 is connected through tee T 7 with butt tube 3.
In the flow matches device of the present invention, pressure-sensitive diaphragm 6 specifically can be using rubber corrugated film or other pressure-sensitive material.
In the flow matches device of the present invention, described regulation handle can be the form such as regulating bolt or valve handle.
During using inventive flow coalignment, by inventive flow coalignment according to being connected to multi-user shown in Fig. 3
In pipeline Material pipeline road.After installation, inventive flow coalignment can adjust pump before pressure to target area, enter
And the coupling realizing flow is adjusted, specific operation process is as follows:
This flow matches device is attached to before the booster pump of each branch line, when (flow before a certain branch line pump
Equipped postpone) reduced pressure when, the active force on pressure-sensitive diaphragm 6 is acted on by pressure feedback pipe 8 and also reduces therewith, now,
Active force on pressure-sensitive diaphragm 6 is less than spring 2 counteracting force set in advance, and spring 2 promotes regulating part guide block 11 to drive and adjusts
Part 9 moves to the direction of pressure-sensitive diaphragm 6, and the double round end keies on regulating part 9 are reduced with the overlapping area in butt tube 3 tube chamber section,
The circulation area of butt tube 3 tube chamber becomes big, and flow resistance diminishes, the pressure release backward of the pressure before flow matches device, and flow increases, thus
After making flow matches device, (before pump) pressure constantly increases, until the active force of pressure-sensitive diaphragm 6 is equal with the counteracting force of spring 2
Till weighing apparatus, after final flow rate coalignment, (before pump) pressure increases to desired value.
In the same manner, when after flow matches device, pressure increases, direction of action is contrary to the above.
When self-checking device occur adjusting deviation or accordingly slow when, also can be adjusted manually by regulation handle 1,
To control to adjust the movement of part 9, to change the circulation area of butt tube 3 tube chamber, realize the coupling of flow.During practical application, can root
Screen the diameter of pressure-sensitive diaphragm and thickness according to concrete operating mode to determine the reasonable stroke of regulating part 9.
