Technical field
The present invention relates to surveying instrument technology, particularly relate to a kind of technology of linerless inner duct type necking down electromagnetism water meter.
Background technology
Electromagnetism water meter is a kind of instrument for rate-of flow in measuring channel, during use, it is connected with the flange of tested pipeline, can measure the rate-of flow in tested pipeline.
Electromagnetism water meter is generally used for closed full-section pipe-flow and measures, as shown in Figure 4, the measuring tube of tradition electromagnetism water meter is all straight tube double-decker, at uninsulated body 21 inwalls, be coated with one deck insulated liner 22, insulated liner 22 is for avoiding the vortex flow loss of measuring process, guarantee measuring accuracy, be welded together with respectively for connecting the flange 26 of tested pipeline at the two ends of body 21, this traditional electromagnetism water meter has following defect:
1) in the situation that caliber is certain, the medium in tested pipeline is during full packages, and the medium in measuring tube is also full packages not, thereby can cause measurement result to occur error;
2) two flanges directly weld and put on measuring tube, and two flanges can directly contact measured medium, so be also coated with one deck insulated liner on flange sealing surface, insulated liner on flange face in measuring media process easily because of negative pressure and thermal shock impaired, thereby cause flange portion to produce vortex flow loss, have influence on the reliability of measurement result;
3), once the insulated liner layer of measuring tube is impaired in measuring media process, just easily causes generation vortex flow loss in measuring tube, thereby have influence on the reliability of measurement result.
Summary of the invention
For the defect existing in above-mentioned prior art, technical matters to be solved by this invention be to provide a kind of can be in tested pipeline medium effectively do not reduce measuring error during full packages, vortex flow loss can be avoided, thereby the linerless inner duct type necking down electromagnetism water meter of measurement result reliability can be improved.
In order to solve the problems of the technologies described above, a kind of linerless inner duct type necking down electromagnetism water meter provided by the present invention, comprise measuring tube, watermeter shell, and two flanges, it is characterized in that: on described watermeter shell, be fixed with two water conservancy diversion Taper Pipes, the narrow end mouth of pipe of the two ends mouth of pipe of described measuring tube and two water conservancy diversion Taper Pipes is coaxial docking respectively and fixes, and the joint portion of measuring tube two ends and two water conservancy diversion Taper Pipes seals by O-ring seal respectively;
Each is arranged on described two flanges respectively on the outer wall of two water conservancy diversion Taper Pipes through jump ring.
Further, described measuring tube is the linerless inner necking down pipe of an electric insulation.
Further, the internal diameter of the narrow end mouth of pipe of described water conservancy diversion Taper Pipe and the internal diameter of measuring tube are consistent.
Further, in described watermeter shell, be fixed with water meter movement and electric battery.
Further, described watermeter shell is a polygon housing.
Linerless inner duct type necking down electromagnetism water meter provided by the invention, two water conservancy diversion Taper Pipes at the two ends of measuring tube, have been installed additional, by the rectification of water conservancy diversion Taper Pipe, can guarantee as much as possible that in measuring tube, medium can reach full packages or approach full packages state, can be in tested pipeline medium effectively do not reduce measuring error during full packages, and two flanges are arranged on respectively on the outer wall of two water conservancy diversion Taper Pipes by jump ring, flange and measuring tube are separated from each other, directly do not contact measured medium yet, thereby on flange sealing surface, do not need insulated liner yet, in measuring process, flange can not produce vortex flow loss yet, can improve the reliability of measurement result.Further, measuring tube adopts the linerless inner necking down pipe of electric insulation, can avoid producing vortex flow loss in measuring tube, can further improve the reliability of measurement result.
