Abstract
The utility model relates to a structure of a magnetoelectric flowmeter which is particularly applicable to occasions having low requirement for fluid medium. The flowmeter has a section of tubular shell body connected with a pipe containing fluid body to be detected; the pipe wall of the shell body is provided with a meter and a magnetic block which are radially arranged at the outer side; the meter is connected with a probe extending in the tubular shell body and placed in the magnetic field; one side of the probe is provided with a triangular prism shaped vortex generator parallel to the probe and radially penetrating the inner hole of the tubular shell body. The flowmeter is characterized in that one end of the generator is blindly inserted in the pipe wall of the tubular shell body and the other end is tightly pressed and sealed by a stopper through a thread. When washed or twisted, the vortex generator of the flowmeter can be replaced or discarded without discarding the whole flowmeter, and the problems concerning the accuracy restoration and the pipe system blockage of the flowmeter can be solved on site.
Description
Technical field
The utility model relates to the structure of magneto-electric flowmeter, is specially adapted to fluid medium and requires low occasion.
Background technology
The magneto-electric flowmeter, has one section tubular shell that links with the detected fluid pipeline, be provided with the gauge outfit and the magnetic patch of radially installation on the tube wall of this housing in the outside, gauge outfit is associated with a probe of stretching in tubular shell, probe is in the magnetic field, in a side of described probe, be provided with one with it parallel alley to the triangular prism shaped eddy generator that passes the tubular shell endoporus.When described flowmeter was worked, the fluid that is passed through can produce whirlpool at the triangular prism place as eddy generator, and produces pulse signal thus, and gauge outfit is extracted these signals by probe, demonstrates flow value by conversion.The form accuracy of eddy generator directly influences the degree of accuracy of this flowmeter.Therefore, in the magneto-electric flowmeter, eddy generator is a vital part.Yet because this flowmeter generally uses in the relatively poor occasion of fluid media (medium), in pipings such as oil well sewage, paper mill draining, fluid inclusion wherein silt particle, foreign material fiber, stalk slag etc., thereby eddy generator is easily produced erosion, winding.And in the existing magneto-electric flowmeter, eddy generator is directly to be welded on the tubular shell, in case erosion on the eddy generator, heavy wear, winding produce, its form accuracy is promptly destroyed, just can not produce significant whirlpool.Clean up for twining the fault that produces, need disassembling flowmeter again.The one less important expensive time (2-3 hour) of dismounting influences the row of giving continuously of fluid like this.For the fault of erosion on the eddy generator or heavy wear generation, then can only change whole flowmeter, waste is serious.
Summary of the invention
The purpose of this utility model, be that existing magneto-electric flowmeter is improved, make it to become the dismountable magneto-electric flowmeter of its consumable accessory, after its eddy generator or is twined at erosion, can change or clear up this part, and will not scrap by whole flowmeter, and just can solve the precision recovery of flowmeter and the blockage problem of piping at the scene fast.
Above-mentioned purpose is to realize with such technical scheme: the dismountable magneto-electric flowmeter of consumable accessory, has one section tubular shell that links with the detected fluid pipeline, be provided with the gauge outfit and the magnetic patch of radially installation on the tube wall of this housing in the outside, gauge outfit is associated with the probe of stretching in tubular shell, probe is in the magnetic field, side at described probe, be provided with one with it parallel alley to the triangular prism shaped eddy generator that passes the tubular shell endoporus, it is characterized in that, one end of this eddy generator is blind to be inserted on the tube wall of tubular shell, and the other end is compressed and seals by screw thread by plug.Be welded with the outlet port of eddy generator on the described tubular shell, described plug by thread connection in this outlet port.Described magnetic patch is two, is symmetrical in described probe.The end face that described eddy generator goes out to hold earlier is provided with and draws the horse conch hole.
The beneficial effects of the utility model are: by above-mentioned improvement, the consumable accessory eddy generator of magneto-electric flowmeter after by erosion, screws off plug and can pull out replacing, after being wound, also can pull down cleaning.Because eddy generator is detachable, thereby avoided whole flowmeter is scrapped and the halt system operation, and changed or clear up and to solve a problem promptly with regard to carrying out at the scene.Therefore, use the utility model can save the consumption costs of flowmeter in a large number, also convenient production.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Figure 1A-A cut-open view;
Fig. 3 is Figure 1B-B cut-open view.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, the tube wall outside of the tubular shell 3 that links with the detected fluid pipeline, radially connect gauge outfit 1, be coupled to the probe 8 at gauge outfit 1 center, stretch in tubular shell 3, side at probe 8, parallel probe is radially installed triangular prism shaped eddy generator 2, for making eddy generator 2 detachable, take to make it longitudinal register with on the blind tube wall that is inserted in tubular shell 3 of one end, the other end by plug 4 by screw thread be welded on outlet port 5 on the tubular shell 3 and link it is compressed and should locate to seal, during dismounting, screw off plug and get final product, the triangular prism xsect orientation of eddy generator 2 is by both provisioning request was definite, because the occupy-place of outlet port 5, the former magnetic patch that is contained in probe 8 opposites moves to the probe side, for satisfying the magnetic field requirement of flowmeter work, after moving, magnetic patch 7 is two, and symmetry is installed on the outer wall of tubular shell 3 of probe 8 both sides.For making things convenient for eddy generator 2 to pull out, can on its end face that goes out to hold earlier, removal hole be set with tool using, this example is seen Fig. 3 for drawing horse conch hole 6, available at ordinary times screw is sealed, in order to avoid corrosion and foreign material are inserted.
