Description
Technical field
The present invention relates to a kind of by measuring upper-lower position of the choked flow part being located in direct current pipeline in direct current pipeline
To calculate the device of flow, more particularly to a kind of pointer spinner flowmeter.
Background technology
Spinner flowmeter is made up of two parts, and one is the conical pipe gradually expanded from bottom to top；Another is placed in
In conical pipe and the rotor that can freely up and down be moved along the center line of pipe.Spinner flowmeter is when measuring the flow of fluid, quilt
Fluid measured flows into from conical pipe lower end, and the impact flow of fluid rotor, and to it produce an active force (this power it is big
It is small to change with uninterrupted)；When flow is sufficiently large, rotor picking-up is allowed to raise by caused active force.Meanwhile
Detected fluid flows through the annular section between rotor and taper tube wall, is flowed out from upper end.When detected fluid flows to the work of rotor
Firmly, it is exactly equal to (referred to as show weight) during the weight of rotor in a fluid, rotor stress is in poised state and rested on
A certain height.Analysis shows；Position height of the rotor in conical pipe, there is mutual corresponding relation with the flow passed through.
Therefore, position height of the rotor in conical pipe is observed, it is possible to try to achieve corresponding flow value.Rotor it is vertical on
Lower linear motion passes through Electromagnetic Coupling System transmission, is converted into the rotation of needle pivot, passes through the pointer being combined into one with needle pivot
Rotate to indicate the instantaneous delivery of medium.Spinner flowmeter is at the scene during use, because medium instantaneous delivery is too small or not
Stabilization, operating pressure are low or unstable, and the change of instrument fore-and-aft survey internal diameter of the pipeline is excessive, and front and rear straight length serious non-compliance uses
Regulation requires that especially measuring can cause the flowing of flow measurement buret certain media extremely unstable when medium is gas, draw
Play rotor and jumping phenomena occurs.The jumping phenomena that float rotor occurs in flow measurement buret passes to pointer, reforms into refer to
The dancing that pin does not stop continuously, cause flow instruction unstable, or even scale value can not be read at all, determine instantaneous delivery
Numerical value.If such a phenomenon occurs in scene, common processing method is to analyze the main reason for causing the beat of pointer, most cases
Under taken measures from technique, improve media flow situation, so as to reduce, avoid the swing of pointer.But many times pointer
Frequency, the amplitude of swing are difficult fundamentally to avoid, reduce more.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, there is provided a kind of pointer spinner flowmeter, the flowmeter solve
Deficiency, rational in infrastructure existing for existing flowmeter, can improve the using effect of flowmeter, makes frequency, the amplitude of the beat of pointer
It is greatly lowered, pointer instruction is stable, and scale value, which is read, becomes easy, and reading accuracy improves, technology to be solved by this invention
Problem is to increase the damping unit of the anti-beat of pointer, can slow down the frequency of the beat of pointer when jumping phenomena occurs for rotor, reduce
The amplitude of the beat of pointer, it is ensured that pointer instruction is stable, and the technical solution used in the present invention is as follows：The present invention is included from bottom to top
The conical pipe that gradually expands and be placed in the rotor that can be moved along the center line of pipe in conical pipe and freely up and down and by pointer,
Pointer tabletting, hand rest, the indicating hand component of counterweight composition, it is characterised in that also including a damping unit, damping unit installation
It is integrally formed below pointer scale disk, and with dial, the damping unit includes what is be made up of two pieces of metallic plates and connector
Framework and the magnet steel being pull-in on the inside of two pieces of metallic plates, there is gap between the magnet steel on the inside of two pieces of metallic plates, form a closure
Magnetic field, the counterweight in indicating hand component can freely swing in this gap.
The action principle of the present invention is as follows, and the counterweight in indicating hand component is conducting metal aluminium alloy, is determined according to electromagnetic induction
Rule, moves with focusing in magnetic field, cutting magnetic line, necessarily leads to induced electromotive force, so as to produce vortex flow in counterweight；Magnetic
Field necessarily leads to active force to energized conductor, and this active force plays a part of hindering to match somebody with somebody to focus in magnetic field to move just, counterweight
The speed of motion is bigger, and caused reaction force is also bigger, and its effect is similar to damper, due to counterweight and pointer, pointer pressure
It is integrated after the assembling such as piece, hand rest, so as to which damping unit can play a part of reducing beat of pointer frequency, amplitude, reaches
Stablizing effect.
Compared with prior art, the present invention is rational in infrastructure, can improve the using effect of flowmeter, make the frequency of the beat of pointer
Rate, amplitude are greatly lowered, and pointer instruction is stable, and scale value, which is read, becomes easy, and reading accuracy improves, and both improves efficiency,
It in turn ensure that measurement accuracy.
Brief description of the drawings
Accompanying drawing 1 is front view of the present invention.
Embodiment
