Abstract
The utility model relates to a sensor of V-shaped cone flow meter, which comprises a flow meter pipeline 5 and an L-shaped cone body 1 with central through hole; the pipe wall of the flow meter pipeline 5 is provided with a hole; the hole opening is welded with a cylindrical sensor port 4; and the upper opening of the sensor port 4 is provided with screw threads. The sensor also comprises a pressure conducting part 2 and a fixed pressure cap 3; the cross section of the pressure conducting part 2 is in the shape of ''T''-shaped cylinder; a high pressure side pressure conducting hole P1 and a low pressure side pressure conducting hole P2 are arranged left and right on the cylinder body of the pressure conducting part 2 respectively, the lower end of the low pressure side pressure conducting hole P2 is welded with the upper end of the cone body, and the two holes are communicated with each other; the pressure conducting part 2 connected with the cone body is inserted in the sensor port 4; and the fixed pressure cap 3 with inner screw threads compacts the pressure conducing part 2 and is screwed on the upper opening of the sensor port. The utility model is convenient to mount, and the cone body is simple, convenient and easy to wash and maintain and can be processed on line; and when the flow parameters of the user pipeline are changed, the cone body and the pressure conducting part are replaced only, thereby reducing replacement cost of the flow meter.
Description
Technical field
The utility model belongs to the field of industrial small-caliber pipeline liquid flow measurement.
Background technology
The V-type cone flow meter is a kind of differential pressure flowmeter that is combined by V awl sensor (cone-shaped body) and differential pressure transmitter, can accurately measure the flow of various media in the wide reynolds number range.The V-type cone flow meter utilizes throttling effect to measure flow.Compare with other throttling bodies, it has changed the throttling layout, changes the ring-type throttling into from traditional center pit throttling, and promptly V awl sensor is to utilize a streamlined cone-shaped body to be suspended on pipeline center fluid is retracted to pipeline inner edge wall gradually.The throttling effect of this novelty makes it have self-rectifying, self-cleaning, self-shield characteristic, sees from the actual operating position of lots of field, and V awl sensor stream measures dose-effect and really is better than other differential pressure pick-up.
The sensor of V-type cone flow meter is in actual manufacture process, and the mode that the suspension of V awl sensor is fixed on pipeline center is its main points.Traditional way is that low pressure connecting pipe among Fig. 27 and cone-shaped body 1 are fixed together; Then with low pressure connecting pipe 7 with pass the low pressure hole of having held successfully on the flow process pipeline 5, low pressure connecting pipe 7 and high pressure connecting pipe 6 are welded on the flow process pipeline 5 after adjusting the position of cone-shaped body 1.Adopt the mode of this manufacturing very high, be not easy to operation the requirement of connecting pipe 7 welding preceding cone-shaped body position adjustment.On the other hand, under abominable working environment, when needing artificial cleaning sensor cone, need pull down whole flowmeter pipeline, and clean very difficultly for the sensor of tubule run-off meter, increase the workload and the difficulty of clean and maintenance.
Summary of the invention
The purpose of the utility model be exactly provide in order to overcome the above problems a kind of have install and the daily clean and maintenance sensor of V-type cone flow meter conveniently.
The technical scheme of the utility model is design like this: a kind of sensor of V-type cone flow meter; Comprise flowmeter pipeline 5, the L shaped cone-shaped body 1 that is provided with central through hole; Be characterized in: on flowmeter pipeline 5 tube walls, have the hole; The hole is welded with the sensor port 4 of tubular, the screw thread that is provided with suitable for reading of sensor port 4; It comprises that also xsect is columned pilot parts 2 of " T " font and the fixedly pressure cap 3 that has internal thread; About on the right cylinder of pilot parts 2, have high-pressure side pressure guide hole P1 and low-pressure side pressure guide hole P2, the lower end of low-pressure side pressure guide hole P2 and the upper end of cone-shaped body 1 weld together, and low-pressure side pressure guide hole P2 communicates with the center pit of cone-shaped body 1; The pilot parts 2 that combine as a whole with cone-shaped body 1 insert in the sensor port 4, and fixedly pressure cap 3 compresses pilot parts 2 and is tightened on the suitable for reading of sensor port 4.
The utility model is easy for installation, and the cone-shaped body clean and maintenance is simple and easy to do, can onlinely carry out; And after the user pipe flow parameter changes, need only change cone-shaped body and the pilot parts get final product, reduce the cost of flowmeter replacing.
