Abstract
The present invention relates to the structure of the assembling element of eddy-current flowmeter, this flowmeter is used in the measuring technique measuring liquid or gas.Task of the present invention is that the mistake eliminating sensing element is installed.Be fixed with the assembling element (1) of the impeller (2) of the sensor of eddy-current flowmeter above, from side, inseparable turning up the soil is connected with the columniform main body for transducer, and being fixed on flat cup dolly (4) from inseparable the turning up the soil of this assembling element of opposite side (1), sensing element (2) is fixed on this base (4) by inseparable the turning up the soil of seal (5).Assembling element (1) is the flange of the quadrangle form be made up of thick sheet metal, is processed with the hole (6 for tightening member at four angles place of this flange
1-6
4), and to make the mutually the same mode of the distance between in each edge two holes (6) arrange described hole in a pair of this flange relative two edge (7) and (9), and another on relative two edge (8) and (10) to make the mode different from each other of the distance between in each edge two holes (6) arrange above described holes, and those holes above-mentioned are arranged symmetrically relative to the longitudinal axis of flange.Seal (5) is the middle part protruded on the flange (10) of quadrangle form.Main body (3) has the two-stage hollow cylinder being with female open end, and have through breach (11) on the wall of the ridge of the cylindrical whole protuberance of that one-level large diameter.By being arranged to value different from each other by another of assembling element to the distance between two holes in each edge in two relative edge, can ensure that sensing element is arranged on device in mode accurately uniquely.
Description
Technical field
The present invention relates to the swirlmeter with measuring in the measuring technique of liquid or gas flow.
Background technology
The current assembling element that the sensing element of swirlmeter is housed above used aborning is known.
Above-mentioned known assembling element from side inseparable turn up the soil be connected to for piezoelectric transformer cylinder-shaped body, and being fixed to flat cup dolly from inseparable the turning up the soil of opposite side, sensing element is fixed on cup dolly by inseparable the turning up the soil of seal.This assembling element is the shape be made up of thick sheet metal is the flange of quadrilateral, is processed with the hole for tightening member at four angles place of this flange, and the distance between two holes simultaneously in all edge is identical.
There is following shortcoming in above-mentioned known assembling element: eddy current type sensing element must to be arranged in the main body of flowmeter with the attitude determined (this sensing element is in face of on the flow direction of liquid or gas), but due to the hole of four on the assembling element distance be arranged between two holes be identical, this will cause sensing element continually setup error to occur, thus cause necessary stripping device, then sensing element is reinstalled on the apparatus.
Summary of the invention
Task of the present invention is the possibility of the setup error eliminating sensing element.
Above-mentioned task is completed by following technical solution: in the structure of the impeller assembling element of the puzzled element of the biography that can prevent setup error from occurring, be connected from side with inseparable the turning up the soil of cylinder-shaped body for piezoelectric transformer, and be fixed to partially flat cup dolly from inseparable the turning up the soil of opposite side, sensing element is fixed on the base by inseparable the turning up the soil of seal, this assembling element is the quadrilateral flange be made up of thick sheet metal, four angles of this flange are formed the hole for tightening member, simultaneously, with the hole making the mutually the same mode of the distance between in each edge two holes arrange above-mentioned corner place in a pair of this flange relative two edge, it is characterized in that: this flange another in two relative edge with the hole making the different mode of the distance between in each edge two holes arrange above-mentioned corner place, and make the hole in above-mentioned other a pair relative two edge be symmetrical relative to the longitudinal axis of flange, so just can ensure that sensing element is arranged on device with the unique attitude determined.
Technique effect is the setup error eliminating sensing element.
The assembling element of the application is compared with the product of prior art, and its substantive distinguishing characteristics is: be configured to different numerical value at another of flange to the distance between two the respective holes in two relative edge, realize above-mentioned technique effect whereby.
The assembling element of the application has a wide range of applications in measuring technique, particularly on swirlmeter, therefore meets the regulation of industrial applicibility.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described:
Fig. 1 is total figure of assembling element of the present invention;
Fig. 2 is the vertical view of the installation elements with rectangular shape;
Fig. 3 is the vertical view of the installation elements with isosceles-trapezium-shaped.
Embodiment
By the assembling element 1 being used for the impeller of sensing element 2 (Fig. 1), from side, inseparable turning up the soil is connected with the cylinder-shaped body 3 for piezoelectric transformer (not shown), and being fixed to flat cup dolly 4 from inseparable the turning up the soil of opposite side, sensing element 2 is fixed on base 4 by inseparable the turning up the soil of seal 5.Assembling element 1 is the flange of the quadrilateral shape be made up of thick sheet metal, is formed with the hole 6 for tightening member (at Fig. 2, not shown in 3) at four angles place of this flange
1-6
4to make the mutually the same mode of distance between in each edge two holes arrange described hole 6 in a pair of this flange relative two edge 7 and 9, and another in two relative edge 8 and 9 to make the mode different from each other of the distance between in each edge two holes arrange described hole 6.And the shape of flange can be rectangle (Fig. 2) or isosceles trapezoid (Fig. 3), seal 5 is parts that middle part is protruding on the flange 1 of quadrangle form.Main body 3 has the two-stage hollow cylinder being with female open end, and wall in the spine of the cylindrical all projections of that one-level that diameter is large is formed with through otch 11.
By on swirlmeter by another in two relative edge to make the mode different from each other of the distance between in each edge two holes arrange described hole, compared with the product of prior art, the generation that sensing element mistake is installed can be eliminated when assembling.
