Abstract
The utility model provides a turbine liquid flow meter, which comprises a shell, a preposing pipe section, an impeller, a postposing pipe section and a preamplifier, wherein, the shell is arranged between the preposing pipe section and the postposing pipe section, the impeller is arranged in the inner cavity of the shell, the preamplifier is arranged at the upper end of the shell, and the front part of the preposing pipe section is provided with a filter; the filter comprises a filter housing, a retainer ring and a filter screen, wherein the filter screen is movably connected with the retainer ring; a bolt tightly connects the retainer ring with the filter housing by a sealing washer; and the filter screen is drum-shaped with front end opening and back end closing. By the filter arranged at the front end of the preposing pipe section of the liquid flow meter, the turbine liquid flow meter can filter out impurities in the measured liquid, thus greatly reducing the effects of the impurities on the impeller and improving the measurement accuracy; and meanwhile the turbine liquid flow meter has the advantages of simple structure and convenient modification and maintenance.
Description
Technical field
The utility model relates to a kind of metering apparatus, is specifically related to a kind of liquid flowmeter.
Background technology
Liquid flowmeter is widely used in industries such as oil, chemical industry, metallurgy, water supply, papermaking.Present liquid flowmeter is a lot, have speed mode, mechanical, electronic type etc., but ubiquity low precision, slow, the inconvenient deficiency of installation and maintenance of reaction, particularly when the many liquid of metering impurity, error is bigger.
Summary of the invention
For solving above the deficiencies in the prior art, the utility model provides a kind of simple in structure, liquid flowmeter that precision is high, convenient for installation and maintenance, is specially adapted to the many liquid of impurity.
Technical solutions of the utility model are:
A kind of turbine liquid flowmeter comprises housing, preposition pipeline section, impeller, rearmounted pipeline section, prime amplifier, housing is between preposition pipeline section and rearmounted pipeline section, impeller is arranged at the housing inner chamber, and prime amplifier is arranged at the upper end of housing, and the front portion of described preposition pipeline section is provided with a filtrator.
Described filtrator comprises filter housing, compacting ring, screen pack, and screen pack and compacting ring are lived and connected, bolt with compacting ring by packing washer and filter housing close proximity.
