Abstract
At present, flow measurement device includes two kinds of patterns, i.e. solder type flow measurement device and flange type flow measurement device, and flange type flow measurement device has dismountable feature, is most widely used；Flange type flow measurement device comprises at least two orifice flanges, a flow-through orifice and flange bolt, a measured hole is provided with each orifice flange, one or more metering orifices are provided with flow-through orifice, because the flow hole number on flow-through orifice and bore dia are all fixed, so that the range of flow of measurement is all fixed, which limits its use occasion and scope.To solve the above problems, develop a kind of flow monitoring orifice plate component, with for solving the problems, such as that flow hole number on flow-through orifice and bore dia are fixed.
Description
Technical field
The present invention relates to air-conditioning technical field, more particularly to a kind of flow monitoring orifice plate component.
Background technology
At present, flow measurement device includes two kinds of patterns, i.e. solder type flow measurement device and flange form flow measurement dress
Put, and flange type flow measurement device has dismountable feature, is most widely used；Flange type flow measurement device is at least wrapped
Two orifice flanges, a flow-through orifice and flange bolt are included, a measured hole is provided with each orifice flange, in metering orifice
Plate is provided with one or more metering orifices, because the flow hole number on flow-through orifice and bore dia are all fixed, thus makes
The range of flow that must be measured all is fixed, and which limits its use occasion and scope.To solve the above problems, develop one
Kind of flow monitoring orifice plate component, with for solving the problems, such as that flow hole number on flow-through orifice and bore dia are fixed.
The content of the invention
Flow monitoring orifice plate component, including pipeline, orifice plate, fixation kit and pressure measuring tube, the pipeline are straight pipe
Section, pipeline centre set orifice plate, and pipeline centre outer periphery sets fixation kit, and the orifice plate is circular, centre setting flow
Hole, orifice plate are divided into A plates and B plates, and the fixation kit is arranged on the outside of orifice plate, and fixation kit includes fixed seat, fixing bolt, institute
State and pressure measuring tube is set in fixed seat, the pressure measuring tube is arranged at left and right sides of orifice plate, pressure measuring tube and pipeline phase
Even, flow monitoring orifice plate component of the present invention, the metering orifice of varying number and different can be realized by changing B plates
Aperture is to adapt to the easy pressure measxurement requirement of different pipe contents, while A plates are provided separately with B plates, and A plates slow down B plates and bear
Pressure, B plates can avoid cavitation, any damage parts damage, be more convenient renewal part, saved raw material, installation side
Just it is reasonable.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Reference numerals list：
1. pipeline, 2. orifice plates, 3. fixation kits, 4. pressure measuring tubes, 5. metering orifices, 6.A plates, 7.B plates, 8. fixed seats, 9. are consolidated

Embodiment
The present invention is described in further detail below according to drawings and examples.
As illustrated, flow monitoring orifice plate component, including pipeline 1, orifice plate 2, fixation kit 3 and pressure measuring tube 4, it is described
Pipeline 1 is flat segments, and orifice plate 2 is set among pipeline 1, and 1 middle outer periphery of pipeline sets fixation kit 3, and the orifice plate 2 is
Circle, centre set metering orifice 5, and metering orifice 5 is concentric reducer's shape, and left side diameter is more than right side diameter, is easy to liquid to pass through
Cavitation erosion is not likely to produce, orifice plate 2 divides is arranged at the outside of orifice plate 2 for A plates 6 and B plates 7, the fixation kit 3, and fixation kit 3 includes solid
Reservation 8, fixing bolt 9, pressure measuring tube 4 is set in the fixed seat 8, and the pressure measuring tube 4 is arranged at orifice plate 2 or so two
Side, pressure measuring tube 4 are connected with pipeline 1.
As illustrated, the diameter of the orifice plate 2 is more than the diameter of pipeline 1, orifice plate 2 is installed between pipeline 1, bears pipeline
The pressure of 1 content flowing, is not easy to pour in pipeline 1, blocks pipeline 1, avoids the generation of unsafe conditions.
As illustrated, 7 one groups of the B plates are no less than two panels, stackable use, and can be used as A plates 6, according to
Advance pressure requirements customization, meets the requirement of the different contents of pipeline 1 and pressure.
As illustrated, the position that the bottom of pressure measuring tube 4 is connected with pipeline 1 is capillary, the pressure of capillary is quick
Sense degree is higher, more accurate and sensitive.
