Abstract
The invention relates to a special-shaped variable inner diameter flow regulation device capable of regulating pressure, and belongs to the technical field of flow regulation. The device comprises flange plates (1) arranged at the two ends of a rigid outer tube (2), the rigid outer tube (2), a pressure regulation hole (3) formed in the rigid outer tube (2), an elastic reducing inner tube (4) arranged in the rigid outer tube (2), a pressure equalizing cavity (5) arranged between the rigid outer tube (2) and the elastic reducing inner tube (4) and round elastic pressure separation plates (6) installed on the flange plates (1). The pressure equalizing cavity (5) is divided by multiple layers of arc-shaped spiral elastic deformable pressure-transmitting membranes which are uniformly distributed, and the membranes are connected with the inner wall of the rigid outer tube (2) and the outer wall of the elastic reducing inner tube (4). The device has the advantages of being simple in structure, obvious in effect and basically free of flowing deformation, fine regulation can be carried out on flow in a steady flow state, stability and continuity are substantially improved, and flow regulation precision is improved.
Description
Technical field:
But the present invention relates to a kind of pressure regulation abnormity inside diameter-variable and transfer the stream device, belong to the Flow-rate adjustment technical field.
Background technique:
The current flux controlling device uses parts such as lock shape, sphere, butterfly, piston shape, taper to adjust area of passage more.But to the requirement of the stream of the accent under the current stabilization state, there is following shortcoming based on the fixed component flow regulator: 1, change flow regulator upstream and downstream hydrodynamic pressure, can influence the fluid proper flow.2, hydrodynamic pressure sharply changes near the flow regulator, exchanges stream device and pipeline and impacts.3, near flow regulator, form whirlpool, easily produce fouling.Flow regulator is regulated requirement for satisfying current stabilization state down-off both at home and abroad at present, in following several respects bigger improvement is arranged: 1, less change fluid flow state.2, preparation process and making material.3, driving mode.4, improve flow control accuracy.But the change of flow regulator surrounding fluid form still causes using always at present flow regulator and can't satisfy the true requirement that current stabilization state down-off is regulated fully.
By literature search, do not find the relevant open report of the accent stream device identical with technical solution of the present invention.
Summary of the invention:
The objective of the invention is to overcome the deficiency of existing flow regulator, but provide a kind of pressure regulation abnormity inside diameter-variable to transfer the stream device.
Structural representation of the present invention and perspective structure schematic representation are shown in accompanying drawing 1,2.
Flow regulator of the present invention by the flange plate (1) that places rigidity outer tube (2) two ends, rigidity outer tube (2), place regulator hole (3) on the rigidity outer tube (2), place pipe (4) in the elasticity reducing in the rigidity outer tube (2), place that all pressures chamber (5) between the pipe (4) and the round and elastic that is installed on the flange plate (1) constitute every pressing plate (6) in rigidity outer tube (2) and the elasticity reducing; Wherein: all press chamber (5) to be separated by the saturating compression elasticity film of the equally distributed arc helical of multilayer deformable; The saturating compression elasticity film of helical deformable links to each other with pipe (4) outer wall in rigidity outer tube (2) inwall and the elasticity reducing respectively.
The used device of the present invention is that the material that market is bought and market is bought prepares according to conventional method.
The advantage that the present invention has is simple in structure, effect does not have rheology obviously, substantially, at current stabilization state downward modulation stream, its stability and continuity have improvement by a relatively large margin, have improved to transfer and have flowed precision.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Fig. 2 is perspective structure schematic representation of the present invention.
Embodiment:
The used device of the present invention is that the material that market is bought and market is bought prepares according to conventional method.Its assembling connects as shown in Figure 1.
Flow regulator of the present invention by the flange plate 1 that places rigidity outer tube 2 two ends, rigidity outer tube 2, place regulator hole 3 on the rigidity outer tube 2, place in the elasticity reducing in the rigidity outer tube 2 and manage 4, place that the round and elastic of all pressing chamber 5 and being installed on the flange plate 1 between the pipe 4 constitutes every pressing plate 6 in rigidity outer tube 2 and the elasticity reducing; Wherein: all press chamber 5 to be separated by the saturating compression elasticity film of the equally distributed arc helical of multilayer deformable; The saturating compression elasticity film of helical deformable links to each other with pipe 4 outer walls in rigidity outer tube 2 inwalls and the elasticity reducing respectively.
During use: transfer the stream device by flange plate 1 rigidity outer tube 2 to be connected with treating accent stream pipeline; Regulator hole 3 is connected with the pressure-feeding apparatus that flows usefulness for accent.
Accent flows through journey: at first injected by regulator hole 3 and initially transfer flowing pressure, and improve the initial flowing pressure of transferring gradually, the diameter that makes the interior pipe 4 of elasticity reducing is half of rigidity outer tube 2 diameters; After this, if transfer flowing pressure to increase, pipe 4 diameters can reduce thereupon in the reducing elasticity, cause in the reducing elasticity pipe 4 the inner fluid flow is corresponding reducing; If transfer flowing pressure to reduce, pipe 4 diameters also increase thereupon in the reducing elasticity, impel the corresponding increase of pipe 4 inner fluid flows in the reducing elasticity.Transfer under the stream mode normal, regulate control by the accent flowing pressure to regulator hole 3, realize the fine setting to pipe 4 inner fluid flows in the reducing elasticity.
Practical application shows: the present invention is simple in structure, easy to use, effect is obvious, and at current stabilization state downward modulation stream, its stability and continuity have improvement by a relatively large margin, has improved and has transferred the stream precision.
