Abstract

The utility model belongs to the improvement of an electric worm gear gas. A signal sensing display system is particularly composed of a magnetic ring, a magnetoelectric sensor, conducting wires and a liquid crystal display device which uses a solar cell and an accumulator as a power supply. The liquid crystal display direct-reading worm gear gas flow meter comprises a quick-demount metering core composed of impellers, an impeller shell and a front rectifier, and a continuous lubricating device composed of an oil storage cavity, a positioning sleeve with a siphonage hole or groove, and small holes on the impeller shell. The utility model mini type, short body, light weight and convenient mounting and demounting, and is capable of reliably and normally working for a long term.

Description

Liquid crystal display direct-reading turbine flowmeter for gas
The utility model belongs to the improvement of the turbine flowmeter for gas that measures gas flow.
Chinese patent 93229036.1 discloses a kind of direct-reading electronic turbine flowmeter for gas, adopt the magnetoelectricity transmission that pulse signal is imported LCD, it obviously has advantage than the flowmeter of mechanical drive counting, but, because project organization is limit, still can not guarantee outfield work reliably and with long-term, especially can not satisfy the outfield and reliably check easily and maintenance.
The purpose of this utility model is to provide a kind of direct-reading turbine flowmeter for gas, and it is not only simple in structure, compact, in light weight, easy to maintenance, and can long-term reliably operate as normal.
The purpose of this utility model reaches like this, in the turbine flowmeter for gas that comprises main casing, magnetoelectric transducer, numeric display unit, be provided with by the magnet ring on the impeller spindle, the magnetoelectric transducer corresponding, pass the transfer wire of locating sleeve and constitute the sensing display system as the liquid crystal indicator of power supply with the solar cell that is contained in the gauge outfit pros and cons respectively and accumulator with magnet ring; Setting comprise with the locating sleeve cooperation place have gap impeller housing, with impeller housing coaxial be provided with its circumferentially with no more than 2 screw retention on main casing preceding rectifier and be clipped in wherein impeller and constitute quick-release and measure core; Setting by the ring-type shoe cream room under the main casing gauge outfit, be erected at the siphon piping that forms by orthogonal some apertures on the locating sleeve that has siphon aperture and groove on the shoe cream room mesospore and the impeller housing and constitute uninterrupted continuous lubrication device.
See embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the local enlarged diagram in K place among Fig. 1.
Fig. 3 is impeller housing and locating sleeve assembling back schematic top plan view.
In Fig. 1,1 for main casing 2 for screw 3 for preceding rectifier 4 for impeller 5 for blowoff valve 6 for impeller housing 7 for being contained in magnet ring 8 on the impeller spindle for being expansion screw for instantaneous liquid crystal display mouth 14 for accumulative total liquid crystal display mouth 15 for the solar cell 13 in gauge outfit front for filler valve 12 for shoe cream room 11 for locating sleeve 10 with the magnetoelectric transducer 9 of 7 corresponding intruments, the gauge outfit that cracks it open rotatable arbitrarily angled 16 is transfer wire, by its magnetoelectric transducer 8 the impeller rotation pulse signal of sensing is imported the liquid crystal display counter.Among Fig. 1 dotted line be depicted as when the flowmeter nominal diameter hour, the not flanged limit of main casing, the flowmeter two ends can directly be connected in the pipe network with bolt after adding sealing gasket.In Fig. 2,17 and 19 for open in the location siphon aperture 18 on the jacket wall for open on the locating sleeve tube wall groove 20 and 21 for O-ring seal 22 for opening on impeller housing 6 aperture radially.Find out that by Fig. 1 the aperture of opening on 6 is 3, have one to parallel to the axis, also have a radially through impeller spindle bearing seat.In Fig. 3,23 is the gap of opening on the impeller housing 6, when needs are changed the metering core, only need lay down screw 2, comprises that 3,4,6 quick-releases that constitute measure cores and just can take out vertically easily.
The utility model has the advantages that small-sized short body, simple in structure, volume is little, in light weight. In the identical situation of measuring index, weight can differ about one times, and not only the material saving also Reduced manufacturing cost. The quick-release metering core so that the metering core of demarcating separately as required can At any time to change, this makes things convenient for the on the spot I﹠M in outfield especially. Profit in the shoe cream room Lubricating oil is by the siphon aperture on the positioning sleeve and the aperture pipeline on the impeller housing, slowly Inject between the impeller shaft bearing, this perfect oiling, oil storage system have guaranteed flowmeter Long-term normal operation and reliable life-span. Because this machine does not adopt charactron and power consumption big Hall element adopts the brilliant demonstration of stream of low-power consumption, and when daytime, solar cell serves as Power supply, night, battery worked on, and power consumption is obviously seldom. Therefore, the utility model New packed battery all can be worked more than 1 year. In addition, gauge outfit is rotatable arbitrarily angled, and also ten Divide user friendly need to selection. In a word, the present invention meets the reality of China, is suitable for In the metering of natural gas, liquefied petroleum gas, artificial coal gas and other industrial gasses, especially suitable Contain the gas dosing of the impurity such as light oil and water with the oil field.
