Abstract
The utility model relates to an automatic flow measurement meter, in particular to a hyperboloidal balance cone flowmeter. The hyperboloidal balance cone flowmeter comprises a measuring tube, one end of which is matched with a flange. The hyperboloidal balance cone flowmeter is characterized in that a hyperboloidal restricting element is disposed in the measuring tube in a matching mode, and balance holes are distributed on an end surface of the hyperboloidal conical restricting element evenly. The hyperboloidal balance cone flowmeter has the advantages of unique structure, good stability and repeatability, high measurement accuracy, fast pressure recovery and small permanent pressure loss.
Description
Technical field
The utility model relates to a kind of flow measurement instrument and meter for automation, especially relates to a kind of hyperbolic formula balance cone shaped flow meter.
Background technology
Flow measurement instrument and meter for automation industry, only has in the market conventional V-type cone flow meter, the cone that may cause due to support bar before and after V-type cone flow meter cantilevered comes off, thereby cause measuring inaccurate, and because the conical surface of the restricting element of V-type cone flow meter is single-curved surface, the flow rate fluctuation that easy appearance is creeped and caused due to fluid, this just makes stability, repeatability and the precision of flowmeter all inadequate; The way that does not also address this is that at present.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, provides that a kind of structure uniqueness, stability, good reproducibility, measuring accuracy are high, pressure recovers hyperbolic formula balance cone shaped flow meter fast, that the permanent compression loss reduces.
The utility model is realized in the following way:
A kind of hyperbolic formula balance cone shaped flow meter comprises and holds one by one the measuring tube that is combined with flange, it is characterized in that: the restricting element that is combined with a hyperbolic conical surface body in above-mentioned measuring tube;
Radial equipartition at the end face of described restricting element hyperbolic conical surface body has equalizing port.
The utility model has following effect:
1) structure is unique: the flowmeter that the utility model provides comprises holds the measuring tube that is combined with flange one by one, it is characterized in that: the restricting element that is combined with a hyperbolic conical surface body in above-mentioned measuring tube; Radial equipartition at the end face of described restricting element hyperbolic conical surface body has equalizing port.
2) good stability, repeatability is high, precision is high: the flowmeter that the utility model provides is to have done a lot of improvement at the V-type cone flow meter of routine, at first increase symmetrical a plurality of balanced hole structure around cone, can carry out balance and dual rectification by stream field, greatly reduce eddy current, vibration and signal noise.The fluoran stream surface of restricting element becomes hyperboloid by the original conical surface simultaneously, and this hyperboloid makes the fluid stream therein contraction slow down, and has greatly reduced the flow rate fluctuation of creeping and causing due to fluid.This just makes stability, repeatability and the precision of flowmeter be greatly improved.
3) pressure recovers fast, permanent compression loss and reduces: the flowmeter that the utility model provides is owing to having increased equalizing port, slowed down fluid through violent contraction and expansion before and after restricting element, thereby make the flow field stable, pressure is restored very soon, reduce the formation of turbulent shear power and eddy current, reduced the loss of kinetic energy.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of the utility model Fig. 1;
Fig. 3 is the structural representation of restricting element of the present utility model.
Embodiment
A kind of hyperbolic formula balance cone shaped flow meter comprises and holds one by one the measuring tube 1 that is combined with flange 3, as illustrated in fig. 1 and 2: the restricting element 2 that is combined with a hyperbolic conical surface body 5 in above-mentioned measuring tube 1.
As shown in Figure 3: the radial equipartition at the end face of described restricting element 2 hyperbolic conical surface bodies 5 has equalizing port 4.
The balance cone shaped flow meter that the utility model provides is a kind of differential pressure type flow measurement sensor, and it and differential pressure transmitter etc. support the use.Be mainly used in measuring the flow of fluid of pipeline of flowing through.Flow is through throttling element 2, and a fluid stream shrinks, and makes rate of flow of fluid increase, pressure decreased, producing Pressure Drop in the front and back of throttling element 2 is differential pressure, and this differential pressure has certain relation with the flow of the pipeline of flowing through, and namely just can obtain the flow of pipeline inner fluid by measuring this differential pressure.Measuring differential pressure can realize with differential pressure transmitter.
Claims (2)
