Abstract
The utility model provides a thereby simple structure, with the closely cooperate electromagnetic water meter's earthing pole structure of lifting means incorruptibility of pipe wall. The utility model discloses a detection water pipe (1), symmetry setting are in a pair of detection electrode (2) and the earthing pole, the winding that detect in water pipe (1) are in detect water pipe (1) outlying excitation coil (3) and fixed the setting detect water gauge (4) on water pipe (1), the earthing pole includes to inlay through the mode of moulding plastics to be established electrode tube (5) in the inner wall of detection water pipe (1), be equipped with on electrode tube (5) with detect radian (6) of water pipe (1) looks adaptation. The utility model is suitable for an electromagnetic water meter makes the field.
Description
Technical field
The utility model relates to a kind of ground structure, particularly relates to a kind of earthing pole structure of electromagnetism water meter.
Background technology
Along with the continuous progress of society, the development of science and technology, more and more novel surveying instrument is extensively adopted by enterprise.Electromagnetism water meter is exactly one of them, and it is widely used the flow measurement in various conductive liquid, especially tap water supply field.Electromagnetism water meter is exactly the flowmeter carrying out measuring water flow according to faraday electromagnetic induction principle, with measuring tube axis and the perpendicular tube wall of the magnetic line of force on a pair detecting electrode has been installed, when conducting liquid is along measuring tube axial-movement, conducting liquid cutting magnetic line produces induced potential, thus measures the fluid flow flow through.General electromagnetism water meter, detecting electrode and earthing pole be symmetrically between two arranged on same vertical plane, and form cross structure, its end is provided with screw thread and through water pipe, is fixed by nut.Such fixed form makes the tight ness rating between earthing pole with tube wall relative poor, is difficult to the robustness ensureing water meter.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides a kind of structure simply, with tube wall to closely cooperate thus the earthing pole structure of the electromagnetism water meter of lifting means durability.
The technical scheme that the utility model adopts is: the utility model comprises and detects water pipe, is symmetricly set on a pair detecting electrode in described detection water pipe and earthing pole, the field coil being wrapped in described detection water pipe periphery and the water meter be fixedly installed on described detection water pipe, described earthing pole comprises the electrode tube be embedded in the inwall of described detection water pipe by the mode of injection moulding, and described electrode tube is provided with the radian suitable with described detection water pipe.
Further, the tube wall of described electrode tube is provided with some through holes.
Further, described electrode tube is through described detection water pipe, and the one end be positioned at outside described detection water pipe at described electrode tube is also provided with threaded hole.
Further, the plane that arranges of described electrode tube and described detecting electrode staggers mutually.
The beneficial effects of the utility model are: detect water pipe because the utility model comprises, be symmetricly set on a pair detecting electrode in described detection water pipe and earthing pole, the field coil being wrapped in described detection water pipe periphery and the water meter be fixedly installed on described detection water pipe, described earthing pole comprises the electrode tube be embedded in the inwall of described detection water pipe by the mode of injection moulding, and described electrode tube is provided with the radian suitable with described detection water pipe.Compared with prior art, ground pipe in the utility model makes strip electrode tube, and on described electrode tube, be provided with the radian suitable with described detection water pipe, both are made closely to be connected, simultaneously in the utility model, described ground pipe is embedded tube wall at described detection water pipe in the mode of injection moulding, and both are one-body molded.So the utility model structure simply, with tube wall closely cooperates thus lifting means durability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises and detects water pipe 1, is symmetricly set on a pair detecting electrode 2 in described detection water pipe 1 and earthing pole, the field coil 3 being wrapped in described detection water pipe 1 periphery and the water meter 4 be fixedly installed on described detection water pipe 1, described earthing pole comprises the electrode tube 5 be embedded in the inwall of described detection water pipe 1 by the mode of injection moulding, and described electrode tube 5 is provided with the radian 6 suitable with described detection water pipe 1.In the present embodiment, described electrode tube 5, in J-shaped structure, because the described radian 6 be wherein provided with is consistent with the radian of described detection water pipe 1 tube wall, makes cooperation between the two tightr; The tube wall of described electrode tube 5 is provided with some through holes 7, and like this when carrying out injection moulding and being fixing, it is one-body molded that the existence due to described through hole 7 makes described electrode tube 5 and described detection water pipe 1 mutually merge, and reinforces cooperation between the two further.Described electrode tube 5 is through described detection water pipe 1, and the one end be positioned at outside described detection water pipe 1 at described electrode tube 5 is also provided with threaded hole 8.In the present embodiment, described electrode tube 5 staggers mutually with the plane that arranges of described detecting electrode 2, and such design can meet the request for utilization of small-bore pipeline, avoids when caliber is too small time, described earthing pole and described detecting electrode contact with each other, and cause the error even damage equipment in measurement.
The utility model is applicable to electromagnetism water meter and manufactures field.
