Description
Technical field:
The present invention relates to a kind of pressure-adjustable abnormity inside diameter-variable and adjust stream device, belong to Flow-rate adjustment technical field.
Background technique:
The parts adjustment area of passages such as current flux controlling device many uses lock shape, spherical, butterfly, piston shape, taper.But to the tune stream requirement under current stabilization state, there is following shortcoming based on fixed component flow regulator: 1, change flow regulator upstream and downstream hydrodynamic pressure, fluid proper flow can be affected.2, near flow regulator, hydrodynamic pressure sharply changes, exchange stream device and pipeline impact.3, near flow regulator, form whirlpool, easily produce fouling.Flow regulator regulates requirement for meeting current stabilization state down-off both at home and abroad at present, has larger improvement: 1, less alter fluidised form in following several respects.2, preparation process and making material.3, driving mode.4, flow control accuracy is improved.But the change of flow regulator surrounding fluid form, still causes commonly using the true requirement that flow regulator cannot meet the adjustment of current stabilization state down-off completely at present.
By literature search, the relevant open report of the tune stream device identical with technical solution of the present invention is not found.
Summary of the invention:
The object of the invention is to the deficiency overcoming existing flow regulator, provide a kind of pressure-adjustable abnormity inside diameter-variable to adjust stream device.
Structural representation of the present invention and perspective structure schematic diagram are as shown in accompanying drawing 1,2.
Flow regulator of the present invention by pipe (4) in being placed in the flange plate (1) at rigidity outer tube (2) two ends, rigidity outer tube (2), the regulator hole (3) be placed on rigidity outer tube (2), being placed in rigidity outer tube (2) elasticity reducing, be placed in all pressures chamber (5) in rigidity outer tube (2) and elasticity reducing between pipe (4) and the round and elastic be arranged on flange plate (1) is formed every pressing plate (6); Wherein: all press chamber (5) to be separated by the saturating compression elasticity film of multilayer equally distributed arc helical deformable; The saturating compression elasticity film of helical deformable respectively with manage (4) outer wall in rigidity outer tube (2) inwall and elasticity reducing and be connected.
The present invention's device used is that the material that market is bought and market is bought conventionally is prepared.
The present invention has that structure is simple, successful, substantially without the advantage that stream becomes, lower stream in current stabilization state, its stability and continuity have improvement by a relatively large margin, improves tune and flows precision.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is perspective structure schematic diagram of the present invention.
Embodiment:
The present invention's device used is that the material that market is bought and market is bought conventionally is prepared.Its assembly connection as shown in Figure 1.
Flow regulator of the present invention by being placed in the flange plate 1 at rigidity outer tube 2 two ends, rigidity outer tube 2, the regulator hole 3 be placed on rigidity outer tube 2, be placed in rigidity outer tube 2 elasticity reducing in pipe 4, all press chamber 5 and the round and elastic be arranged on flange plate 1 be placed in rigidity outer tube 2 and elasticity reducing between pipe 4 form every pressing plate 6; Wherein: all press chamber 5 to be separated by the saturating compression elasticity film of multilayer equally distributed arc helical deformable; The saturating compression elasticity film of helical deformable is connected with pipe 4 outer wall in rigidity outer tube 2 inwall and elasticity reducing respectively.
During use: adjust stream device by flange plate 1, rigidity outer tube 2 to be flowed pipeline and is connected with waiting to adjust; Regulator hole 3 with for adjusting the pressure-feeding apparatus flowed to be connected.
Tune flows through journey: first injected by regulator hole 3 and initially adjust flowing pressure, and improves gradually and initially adjust flowing pressure, makes the diameter of pipe 4 in elasticity reducing be the half of rigidity outer tube 2 diameter; After this, if adjust flowing pressure to increase, reducing flexible inner tube 4 diameter can reduce thereupon, causes the corresponding reduction of reducing flexible inner tube 4 inner fluid flow; If adjust flowing pressure to reduce, reducing flexible inner tube 4 diameter also increases thereupon, impels the corresponding increase of reducing flexible inner tube 4 inner fluid flow.Under normal tune stream mode, by the tune flowing pressure regulable control to regulator hole 3, realize the fine setting to reducing flexible inner tube 4 inner fluid flow.
Practical application shows: structure of the present invention is simple, easy to use, successful, and lower stream in current stabilization state, its stability and continuity have improvement by a relatively large margin, improves and adjusts stream precision.
