Abstract
The utility model provides an installation structure of a differential pressure type wedge flowmeter. The installation structure of the differential pressure type wedge flowmeter comprises a technological pipe section, a V-shaped wedge block and two pressure tapping flanges, wherein the two pressure tapping flanges are respectively arranged on two sides of the V-shaped wedge block on the technological pipe section; a V-shaped opening end of the V-shaped wedge block is fixedly provided with a reinforcing plate; the reinforcing plate is connected with the technological pipe section through multiple connecting pieces; and the connecting pieces are integrally fixed with the reinforcing plate and the technological pipe section in a welding way. According to the installation structure of the differential pressure type wedge flowmeter, as the technological pipe section and the V-shaped wedge block are connected by the connecting pieces, the technological pipe section is not damaged; the quantity and the location of installation holes can be determined according to an actual situation under the premise that the wedge block can bear the impact of equivalent pressure; and by the adoption of the installation structure of the differential pressure type wedge flowmeter, the strength and the comprehensive mechanical performance of the technological pipe section are improved, the roundness and the measure precision of the technological pipe section are improved, the linear cutting procedure is omitted, both the welding rod and the processing time are saved, the production cost is reduced and the working efficiency is improved.
Description
Technical field
The utility model belongs to field of flow meters, is specifically related to a kind of mounting structure of differential pressure type V-Bar Flowmeter.
Background technology
The detection piece of differential pressure type V-Bar Flowmeter is a V font voussoir (claiming again the wedge shape throttling element), its round and smooth drift angle down, the liquid or the thick liquid that are conducive to like this to contain suspended particle pass through smoothly, can not produce at the throttling element upstream side to remain in a standstill.Therefore be particularly suitable in the industries such as oil, chemical industry, being used for the measurement of volumetric flow rate and mass rate.
Fluid is by the wedge flow timing, because the throttling action of voussoir, thereon, the downstream has produced a differential pressure that becomes quadratic relationship with flow value, this differential pressure is drawn from voussoir both sides pressure tappings, deliver to differential pressure transmitter and change electric signal output into, through after the computing of special intelligent Flow Meter Based, can know flow value again.
Traditional V-Bar Flowmeter (300lb, DN 〉=150) voussoir mounting structure (as shown in Figure 1) is that technique pipeline section 1 usefulness line is cut a voussoir shape, again 1 pair of good position (fixing with unit clamp) of V font voussoir 3 and technique pipeline section, then welding, nondestructive examination is perhaps done in pressure testing.But it is original good that this mounting structure causes the intensity of technique pipeline section 1 not have, and increased process costs.Technique pipeline section 1 is wanted line cutting, and after the cutting, the intensity of pipeline section does not have original good, and has increased process costs.Because after the pipeline section cutting, weld with voussoir, bonding area is large simultaneously, increases welding cost; And during built-up welding, pipeline section easily is deformed into ellipse, has affected dimensional accuracy.
The utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of mounting structure of differential pressure type V-Bar Flowmeter.
The utility model is achieved by the following technical solution:
A kind of mounting structure of differential pressure type V-Bar Flowmeter comprises technique pipeline section, V font voussoir and two pressure flanges, and two pressure flanges are separately positioned on the both sides of V font voussoir on the technique pipeline section; It is characterized in that, the V word openend of described V font voussoir is fixedly installed a stiffening plate, and described stiffening plate is connected by a plurality of web members with the technique pipeline section, and described web member and stiffening plate and technique pipeline section are welded and fixed and are integrated.
Further setting of the present utility model is, described web member is pin or screw.
Further setting of the present utility model is, described stiffening plate and V font voussoir are welded and fixed.
Further setting of the present utility model is, the mounting hole that passes web member on the described technique pipeline section all is positioned at the end face of technique pipeline section, and perhaps part is positioned at the end face of technique pipeline section, the side that part is positioned at the technique pipeline section.
The mounting structure of differential pressure type V-Bar Flowmeter described in the utility model is by coupling together technique pipeline section and V font voussoir with web member, so that the technique pipeline section need not destroy, the number of mounting hole and position can be decided according to actual conditions, and can bear with voussoir can with the impact of equal pressure.The utility model has improved technique pipeline section intensity and comprehensive mechanical performance, has improved circularity and the measuring accuracy of technique pipeline section, has saved the line cutting action, has saved welding rod and process time, has reduced production cost, has improved work efficiency.
Description of drawings
Fig. 1 is the mounting structure of differential pressure type V-Bar Flowmeter in the prior art;
Fig. 2 is the mounting structure of differential pressure type V-Bar Flowmeter in the utility model.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, the utility model provides a kind of mounting structure of differential pressure type V-Bar Flowmeter, comprises that technique pipeline section 1, V font voussoir 3 and 2, two pressure flanges 2 of two pressure flanges are separately positioned on the both sides of V font voussoir on the technique pipeline section 1; The V word openend of described V font voussoir 3 is welded and fixed and is provided with a stiffening plate 4, described stiffening plate 4 and technique pipeline section 1 by a plurality of web member 5(such as pin or screw etc.) be connected, described web member 5 is welded and fixed with stiffening plate 4 and technique pipeline section 1 and is integrated.If pressure is too large, also can make a call to again two holes in technique pipeline section 1 side, load onto web member 5 after, pile with again welding rod.Flaw detection is perhaps done in all good rear pressure testings of welding, and flaw detection meets the requirement of II level.
The above is preferred embodiment of the present utility model, and all equivalent variations of doing according to the utility model claim all should belong to protection domain of the present utility model.
