In figure, each mark is as follows:
1 regulating handle, 2 springs, 3 butt tubes, 4 edge face sealing members, 5 end caps, 6 pressure-sensitive diaphragms, 7 three-way pipes, 8 pressure feedback pipes, 9 adjusting elements, 10 lip rings, 11 adjusting element guide blocks.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further, but the utility model is not limited to following examples.
As shown in Figure 1, be the flow matches device that is applicable to multiple-limb pipeline mass transport that the utility model provides, it comprises butt tube 3, adjusting element 9, pressure-sensitive diaphragm 6, pressure feedback pipe 8, regulating handle 1 and spring 2.This adjusting element 9 comprises a body of rod (in figure not mark) and is arranged at the two round end keies (not marking in figure) on this body of rod, and wherein this body of rod is cylindrical, and its diameter equates with the thickness of pair round end keies.As shown in Figure 2, along the footpath of butt tube 3 upwards, the above-mentioned adjusting element 9 that is tightly connected on butt tube 3, and this adjusting element 9 can moving radially along butt tube 3.Adjusting element 9 specifically seals by edge face sealing member 4 and lip ring 10.The two ends of the body of rod all extend to outside the cavity of butt tube 3, and its one end connects adjusting element guide block 11, spring 2 and regulating handle 1 successively; The outer wall of butt tube 3 and end cap 5 form cavity (not marking in figure), the other end of the body of rod is along extending in above-mentioned cavity and being 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, the other end of this pressure feedback pipe 8 is connected with butt tube 3, to realize perception and the feedback to the pressure in butt tube 3.In the utility model, a three-way pipe 7 is set on end cap 5, pressure feedback pipe 8 is connected with butt tube 3 through three-way pipe 7.
In flow matches device of the present utility model, pressure-sensitive diaphragm 6 specifically can adopt rubber corrugated film or other pressure-sensitive material.
In flow matches device of the present utility model, described regulating handle can be the form such as adjusting bolt or valve handle.
While using the utility model flow matches device, by the utility model flow matches device according to being connected in shown in Fig. 3 in multi-user's pipeline mass transport pipeline.After installation, the utility model flow matches device can regulate the front pressure of pump to target area, and then realizes the match and regulate of flow, and specific operation process is as follows:
This flow matches device is mounted to before the suction booster of each branch line, when before a certain branch line pump when (after flow matches device) pressure decreased, the active force acting on pressure-sensitive diaphragm 6 by pressure feedback pipe 8 also reduces thereupon, now, active force on pressure-sensitive diaphragm 6 is less than the predefined reaction force of spring 2, spring 2 promotes adjusting element guide block 11 and drives adjusting element 9 to move to the direction of pressure-sensitive diaphragm 6, two round end keies on adjusting element 9 reduce with the area that overlaps in butt tube 3 tube chamber cross sections, it is large that the circulation area of butt tube 3 tube chambers becomes, flow resistance diminishes, the pressure release backward of pressure before flow matches device, flow increases, thereby (before pump) pressure after flow matches device is constantly increased, until the reaction force of the active force of pressure-sensitive diaphragm 6 and spring 2 balances each other, after final flow rate coalignment, (before pump) pressure increases to desired value.
