Abstract
The utility model relates to an integrated inbuilt venturi which mainly comprises an inlet section, a contraction section, a measurement hole, a diffuser section and a regulation section. The calibers of the outer walls of the inlet section, the contraction section, the measurement hole, the diffuser section and the regulation section are ventures with same diameter. The inlet section, the contraction section, the measurement hole, the diffuser section and the regulation section are orderly formed in each caliber. The integrated inbuilt venturi has the advantages that: a. the measurement precision of a strangling device is greatly increased; b. the material cost is saved by about five times, thereby saving resources; c. the leak source phenomenon does not occur; d. the integrated inbuilt venturi not only withstands the gravitational force of a pipe, but also increases the tensile strength of the product.
Description
Technical field
The utility model relates to a kind of venturi, particularly relates to a kind of integrated built-in venturi.
Background technology
As shown in Figure 1, whole venturi can be divided into five sections operation intervals, be respectively entrance, contraction section, measured hole, diffuser, adjust five parts such as section, function is as follows: entrance and pipeline welding, and steady flow velocity make the measured medium that enters into contraction section begin to measure under stable status.Contraction section is with the size of medium smooth transition to measured hole, and it is minimum that the pressure loss is reduced to.The measured hole place is the flow velocity that measured medium is changed to an aperture that requires in theory, and will this moment the pressure of measured medium measure and continue to employ.Diffuser is the interval of connecting tube and measured hole, and main effect is to make measured medium evenly be amplified to the normal flow of pipeline.Adjusting section is to keep for the adjustment distance of pipeline and this throttling device venturi, restriction device and pipeline are when installing, pipeline can be given length in reserve of restriction device, make venturi energy normal mounting in the middle of pipeline, but because pipeline is sectional joining, some error on the size is adjusted section so stay, make install more convenient more smooth.
The work inconvenience of venturi on the market: whole restriction device is divided into five sections, and process is respectively five sections shears, roll bending, welding, pipe is to the pipe welding again, and whole process is in roll bending, in the welding, to material, technological requirement is quite strict, and will carry out the X ray Non-Destructive Testing to product, roll bending, welding and detection, any one link is made mistakes, and mistake is produced significant impact to product quality.
The utility model content
The utility model will solve the defective of above-mentioned prior art, and a kind of integrated built-in venturi is provided.
The utility model solves the technical scheme that its technical matters adopts.This integrated built-in venturi, mainly comprise entrance, contraction section, measured hole, diffuser and adjustment section, the outer wall caliber of described entrance, contraction section, measured hole, diffuser and adjustment section is the venturi of same diameter, and forms entrance, contraction section, measured hole, diffuser and adjustment section successively in this caliber inside.
The described venturi structure that is formed in one.
The effect that the utility model is useful is: the measuring accuracy that 1, has improved this kind restriction device greatly; 2, on material cost, saved approximately 5%, saved resource than in the past; 3, can not produce " leak source " existing picture; 4, both can resist pipeline gravitation, increase the tensile strength of product itself again.
Description of drawings
Fig. 1 is the main TV structure synoptic diagram of prior art;
Fig. 2 is a main TV structure synoptic diagram of the present utility model;
Description of symbols: entrance 1, contraction section 2, measured hole 3, diffuser 4, adjustment section 5.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described further:
As shown in Figure 2, this integrated built-in venturi, mainly comprise entrance 1, contraction section 2, measured hole 3, diffuser 4 and adjust section 5, the outer wall caliber of described entrance 1, contraction section 2, measured hole 3, diffuser 4 and adjustment section 5 is the venturi (being originally the structure that becomes diameter) of same diameter, the venturi structure that is formed in one, and form entrance 1, contraction section 2, measured hole 3, diffuser 4 in this caliber inside successively and adjust section 5.
Venturi of the present utility model improves from manufacture craft, formed the entrance of venturi, contraction section, measuring section, diffuser is adjusted the integrally formed way of section and is processed venturi, at first customizes the venturi forging of this kind specification from forging factory, use specific mould clamping then, the Vehicle Processing one-shot forming.
Venturi of the present utility model and the contrast of old-fashioned venturi characteristics.
One, precision: precision is the highest behind the old-fashioned venturi girth sheets guarantees in 0.5mm, and the place one's entire reliance upon precision of lathe of the precision after the processing of our adopting said method can reach more than the 0.05mm, has improved the measuring accuracy of this kind restriction device greatly.
Two, economical with materials: old-fashioned venturi will cut out fan-shaped plate face when blanking, girth sheets becomes cone then, and the waste material that this model face is produced is many.And our venturi of processing can customize forging according to size, and the surplus during just forging process for fuel that Vehicle Processing is fallen has been saved approximately 5% on material cost than in the past, saved resource.
Three, no leak source: old-fashioned venturi can have destruction to the molecular structure of plate in the girth sheets process, in welding, and the quality of wlding, the gimmick of welding all can be influential to the quality of finished product, and finished product will carry out the Non-Destructive Testing X ray.So not only strengthened cost, and the wrong venturi finished product that all can be directed at of any one link produces " leak source " existing picture in application, increased the danger in using greatly.And the venturi that my this kind method is produced will never produce above problem, and can guarantee the high product quality of no leak source under any temperature in application.
Four, increase tensile strength: traditional Venturi tube is all used with a kind of coiled sheet plate and is formed because of belonging to each point in design, the institute so that each point all thickness is identical, this sample is to being a measuring equipment that pipeline pressure is increased, so pipeline itself has also been strengthened its gravitation, we uses the built-in venturi of this one, both can resist pipeline gravitation, increase the tensile strength of product itself again.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
