A variable profiled inner diameter adjusting flow regulator means

The present invention relates to an inner diameter of the flow-regulating device regulating variable profiled, metal flow regulating art. Flow rate adjusting means of the present invention is placed in a rigid outer tube (2) across the flange (1), a rigid outer tube (2), placed in a rigid outer tube surge hole (3) (2), placed adjustable elastic rigid outer tube (2) inside the tube (4), placed in the pressure equalizing chamber (5) between the rigid outer tube (2) and an elastic adjustable tube (4), and mounted on the flange on the circular elastic (1) spacer plate (6) constituting; wherein: each pressure chamber (5) by a multilayer spiral arc uniformly distributed pressure elastic deformable permeable membrane spaced apart; helical deformable elastic membrane osmotic pressure respectively outer rigid tube (2) and an elastic inner wall reducer (4) is connected to the outer wall. The present invention has simple structure, obvious effect, substantially without rheological advantages, in fine-tuning the traffic flow steady state, stability and continuity which have more substantial improvement, improving the flow adjusting accuracy.
