Abstract
The magnetic transmission full-sealing leakage-free flowmeter completely seals a medium in a cavity in the flowmeter by using a sealing sleeve, and measures the medium in a leakage-free flowing process in a magnetic transmission mode. The whole flowmeter consists of a shell, blades, an upper transmission shaft, a lower transmission shaft, an upper magnetic rotor, a lower magnetic rotor, an isolation sleeve, a metering gear set, a display board, a gear set fixer, a pointer and the like. Magnets are arranged in the upper magnetic rotor and the lower magnetic rotor and are respectively fixed on the upper transmission shaft and the lower transmission shaft. An isolating sealing sleeve is arranged between the upper magnetic rotor and the lower magnetic rotor and fixed on the shell, the blades are fixed on the lower transmission shaft, the metering gear set and the display board, the pointer is fixed on the gear set fixing frame, the upper transmission shaft is provided with a driving gear meshed with the gear set, and the whole metering part is not in contact with a medium. The flowmeter changes the original dynamic seal into a static seal. The metering data is clear at a glance, the operation is reliable, the maintenance is convenient, and the phenomena of running, overflowing, dripping and leaking of the medium are thoroughly solved.
Description
The utility model relates to a kind of flowmeter, the hermetically sealed no leakage flow meter of particularly a kind of magnetic drives.
The metering of liquid medium operational throughput at present, the general employing by managing the method that goes out theoretical operational throughput as calculated measured.This metering method in real work because of flow media in managing is subjected to all multifactor impacts bigger, so metering precision is not high.With the isotope method metering, exist apparatus expensive, shortcomings such as measuring cost height.And the flowmeter that adopts other measures and can't solve the run, drip, leak phenomenon of measurement instrument in MEDIA FLOW fortune process, particularly in the course of conveying of high pressure, severe toxicity, inflammable, explosive, radiating medium, can't use, also can't use in occasions such as high vacuum.
The purpose of this utility model provides and a kind ofly with sealing shroud medium is sealed in the flowmeter in the die cavity fully, with the mode of magnetic drives the flow process that medium does not have any leakage is measured.This flowmeter has become static seal with original motive seal.Continuous data comes into plain view, and running is reliable, and is easy to maintenance, thoroughly solves the run, drip, leak phenomenon of medium.
The concrete technical scheme that realizes the utility model purpose is: whole flowmeter is made up of shell, blade, upper and lower transmission shaft and upper and lower magnet rotor, spacer sleeve, measurement gear group and display board, gear set fixed mount, pointer etc.In upper and lower magnet rotor magnet is housed, they are fixed respectively on the upper and lower transmission shaft.One isolating seal cover is arranged between upper and lower magnet rotor, it is fixed on the shell, vanes fixed is on lower drive shaft, measurement gear group and display board, pointer is fixed on the gear set fixed mount, the driving gear that is meshed with gear set is arranged on the last transmission shaft, and whole metering section does not have any contact with medium.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-set bolt and lead sealing, magnet rotor under the 2-, 3-gear set, the last transmission shaft of 4-, 5-pointer, 6-data display board, the 7-spring collar, 8-glass, 9-gear set support, the last magnet rotor of 10-, 11-spacer sleeve, the 12-O-ring seal, 13-fixed head, 14-blade, 15-shell, 16-lower drive shaft.
When the timing of MEDIA FLOW inflow-rate of water turbine, blade 14 can rotate round the axis of lower drive shaft 16 because of the out-of-date thrust to it of MEDIA FLOW, its rotation also drives lower drive shaft 16, following magnet rotor 2 rotates simultaneously, this at present the magnetic force of magnet rotor 2 inner magnets pass the magnets that 11 pairs of spacer sleeves go up in the magnet rotor 10 and produce mutual attraction, go up magnet rotor 10 when therefore magnet rotor 2 rotates down and under the effect of magnetic force, also rotate synchronously thereupon.When last magnet rotor 10 rotates; gear on the last transmission shaft 4 that links with it also rotates thereupon; the gear of respectively organizing that so just drives on the whole gear set 3 rotates by different gear ratios; pointer 5 indicates the rate-of flow data that flow through according to the different number of turns that different gears on the gear set 3 rotate on metering display board 6; finish the overall process of whole flow metering; glass 8 is fixed on the shell 15 by spring collar 7; protection gear set 3; data display board 6; pointer 5 grades prevent that dust, dirt etc. from entering upper impression, and the influence metering shows.
Claims (3)
1, the hermetically sealed no leakage flow meter of a kind of magnetic drives is by shell 15, lower drive shaft 16, last transmission shaft 4, following magnet rotor 2, last magnet rotor 10, gear set 3, gear set support 9, spacer sleeve 11, metering display board 6, pointer 5 compositions such as grade is characterized in that in upper and lower magnet rotor 10,2 magnet being arranged respectively, it is to be fixed on the shell 15 with screw that one spacer sleeve 11 is arranged between the upper and lower magnet rotor 10,2, carries out medium-tight by O-ring seal 12.
2, flowmeter according to claim 1, its metrology features is to have on the transmission shaft 4 gear to be meshing with each other with different gear ratios with gear on the gear set 3, one piece of pointer 5 all is equipped with on each gear top on the gear set 3, after gear rotates, will on metering display board 6, demonstrate continuous data by pointer 5.Transmission shaft 4 metering display boards 6 glass 8 spring collars 7 all are fixed on the gear set support 9 on the age wheels 3, and gear set support 9 is fixed on the spacer sleeve 11 by bolt 1.
3, the measures range and the measuring accuracy of mark on gear ratio that depends on each gear on the gear set 3 according to the measures range and the measuring accuracy of claim 1,2 described flowmeters and the metering display board 6.
