Abstract
The invention relates to a T-shaped flow meter, which is mainly characterized in that a flow measuring element arranged in a measuring pipe is a T-shaped polyhedron which is connected with a computation display unit through a conversion unit. The flow meter can effectively eliminate vortex generated when fluid flows through the flow measuring element and adhesion of dirty fluid, and has the characteristics of stable and reliable work, little pressure loss, high measurement precision, firmness and durability and convenient use and installation. The invention can be used for measuring various fluid media, such as gas, liquid, steam, double-phase fluid, smudge, thick fluid, high-temperature fluid, high-pressure fluid, wear fluid, corrosive fluid, and the like, and for measuring flow of various circular pipes or square pipes with large diameter, medium diameter and small diameter.
Description
Technical field
The present invention relates to a kind of measurement of fluid flow instrument, particularly T shape flowmeter.It is suitable for the flow measurement of various fluids.
Background technology
Flow measurement instrument is a kind of widely used instrument and meter for automation.Utilize the flow measurement instrument of fluid mechanics principle manufacturing to have at present: restriction device, even speed tube class flowmeter, target type meter, bent-tube boiler flowmeter etc.Wherein, target type meter is made up of measuring tube and the flat and thin circular plate type flow measurement element that is arranged in the measuring tube.Owing to the flat plectane that approaches of flow measurement element employing of target type meter, when fluid was flowed through the flow measurement element, this flow measurement element back can produce whirlpool, causes the vibrations of flow measurement element, makes transmission signals produce fluctuation, the reduction measuring accuracy.And whirlpool can also be transformed into heat energy to kinetic energy, causes big crushing, consumes fluid energy.In recent years,, all fail improving aspect the shape and structure of flow measurement element, cause above-mentioned defective still to exist, restricted its development though the manufacturer improves having done aspect the power conversion repeatedly target type meter.
Summary of the invention
The object of the present invention is to provide a kind of T shape flowmeter, it can overcome the deficiency of prior art, and the whirlpool that produces when eliminate fluid is flowed through the flow measurement element effectively prevents the shake of flow measurement element, makes stable signal transmission, improves measuring accuracy, reduces crushing.The adhesion of dirty fluid can be effectively prevented, the requirement of flowmeter can be reduced its forward and backward flow development length.
Its solution is: the flow measurement element that is arranged in the measuring tube is a T shape polyhedron, and it is connected with the calculation display unit through converting unit.And the fluoran stream surface of T shape polyhedron flow measurement element is plane or inner concave arc surface, and it is cone-shaped that its following current face is, and the outer surface of this cone is inclined-plane or inner concave arc surface, and the top of this cone is hemispherical or taper.
The present invention adopts technique scheme, because T-shaped polyhedral flow measurement element, its fluoran stream surface is plane or inner concave arc surface; Can give full play to this fluoran stream surface and accept the ability of fluid impact power; And help fluid dynamic energy moment to be transformed into static energy, and be applied on the fluoran stream surface of this flow measurement element, form ergometry; Become electric signal through converting unit, demonstrate flow by the calculation display unit.Owing to adopt slick and sly mild transient mode to connect between the following current face of flow measurement element and the fluoran stream surface, can not produce peeling off of boundary-layer, and be pyramidal following current face again; Its cone outer surface is inclined-plane or inner concave arc surface, and the cone top is hemispherical or taper, when fluid passes through the following current face of flow measurement element; Can not produce whirlpool, fluid is flow through gently, can avoid the shake of flow measurement element; The flow signal stable transfer can be guaranteed, thereby the degree of accuracy of measurement can be improved.And, can also practice thrift the energy of fluid, the pressure loss is little, can reach purpose of energy saving.
In a word, the whirlpool that flowmeter of the present invention produces when effectively eliminate fluid is flowed through the flow measurement element and the adhesion of dirty fluid have the advantages that stable working is reliable, the pressure loss is little, measuring accuracy is high, sturdy and durable, easy to install.It can measure various fluid media (medium)s like fluid media (medium)s such as: gas, liquid, steam, two phase fluid, dirty, thickness, high temperature, high pressure, wearing and tearing, corrosion, and the flow of the pipe of various large, medium and small bores or square tube pipeline.

Fig. 2, embodiment 2 are the another kind of structural representation of T shape flowmeter.
Embodiment
Describe embodiment of the present invention in detail below in conjunction with accompanying drawing.
Embodiment 1
Among Fig. 1, be that measuring tube 2 middle parts of 300mm are provided with a T shape polyhedron flow measurement element 9 at internal diameter, this flow measurement element 9 through connected power bar 4 be arranged on measuring tube 2 outside converting units 5 and be connected, converting unit 5 is connected with calculation display unit 6.And measuring tube 2 is connected with the flow process pipe flange through connected flange 1, is convenient to on-the-spot installation, dismounting like this.The fluoran stream surface 3 of described T shape polyhedron flow measurement element 9 is the plane, and external diameter is 100mm, and following current face 7 is a cone, and its outer surface is the inclined-plane, and cone angle is 60 °, at the top of following current face 7 for being connected and radius is the hemisphere 8 of 20mm with cone is slick and sly.This flow measurement element 9 is processed by plastic-blasting or coating anticorrosive material; Also can process by wimet or surface hardening technology.It can also be used for special media except that the measurement that is used for the general fluid medium, as contain catalyzer slurry oil, sandy crude, contain the strong medium of wearabilityes such as gas of dust and the measurement of strong corrosive medium such as chemical industry class fluid.
When fluid flow through said flow measurement element 9, the power that flow measurement element 9 is experienced was transformed into electric signal through converting unit 5, or reached calculation display unit 6 together with temperature, pressure signal, showed the mass rate or the standard volume flow of measured fluid by it.
Embodiment 2
Among Fig. 2, the fluoran stream surface 3 of T shape polyhedron flow measurement element 9 is an inner concave arc surface, and following current face 7 is a cone, and its outer surface is an inner concave arc surface, and the top of following current face 7 is and the slick and sly hemisphere 8 that is connected of cone.
Shown in Figure 2 is to adopt a kind of plug-type syndeton between T shape polyhedron flow measurement element 9 and the measuring tube, and it is applicable to installing and using during existing pipeline carries out equipment rebuilding.Its concrete connected mode is: flow process pipeline 11 is as the measuring tube of flowmeter; Pipeline axial is provided with a rectangular channel in the duct wall upper edge of this flow process pipeline 11; On the duct wall of this groove position, be fixedly connected with pedestal 10, a center pit 12 that T shape polyhedron flow measurement element 9 is passed through is arranged in the pedestal 10.When T shape polyhedron flow measurement element 9 when the center pit 12 of pedestal 10 is inserted into the precalculated position the flow process pipeline 11, with said flow measurement element 9 half-twists, its fluoran stream surface 3 is got final product over against direction of flow, other is all with embodiment 1.
