Description
Technical field
The utility model belongs to measuring instrument design production field, is specifically related to a kind of ultrasonic flowmeter.
Background technology
Ultrasonic flow rate measuring table is to utilize ultrasound wave time difference principle, realize the device that liquid or gas flow are measured, compare with traditional mechanical type gauging table, ultrasonic flow rate measuring table has the advantages such as low, the high accuracy of measuring of initial-flow is high, crushing is little, just because of these good characteristics, ultrasonic flow rate measuring table is widely used in the fields such as oil, chemical industry, metallurgy, electric power, plumbing.The meter casing structure of most ultrasonic flowmeter is in the market all simple fastening, watchcase internal environment and external environment are basic identical, yet flowmeter is generally all arranged in comparatively moist environment, the environment of this humidity can produce heavy corrosion to each components and parts of watchcase inside, has greatly affected the serviceable life of flowmeter.
Utility model content
The purpose of this utility model is to provide a kind of mildew-resistant, protection against the tide, etch-proof ultrasonic flowmeter.
For realizing above object, the technical solution adopted in the utility model is: a kind of ultrasonic flowmeter, comprise the conduit passing for fluid, described conduit is provided with two for transmitting or accepts hyperacoustic transducer, described transducer is connected with data processing module, described data processing module is connected with flow indication module, also comprise for each module is carried out to supplying cell, described transducer, data processing module, flow indication module and battery are all positioned at a seal casinghousing, and described conduit runs through seal casinghousing setting.
Technique effect of the present utility model is: all modules in conventional flow scale are all placed in the oxygen-free environment of a sealing, have effectively avoided flowmeter because of infringement moist, that corrosion causes inner member.
Accompanying drawing explanation
Fig. 1 is cut-open view of the present utility model.
Embodiment
As shown in Figure 1, a kind of ultrasonic flowmeter, comprise the conduit 10 for treating that fluid measured is passed through, described conduit 10 is provided with two for transmitting or accepts hyperacoustic transducer 11, described transducer 11 is connected with data processing module 12, and described data processing module 12 is connected with flow indication module 13; Also comprise for each module is carried out to supplying cell 14, described transducer 11, data processing module 12, flow indication module 13 and battery 14 are all positioned in a seal casinghousing, described conduit 10 runs through seal casinghousing setting, and described seal casinghousing is provided with for the inner chamber of seal casinghousing being carried out to the valve 221 of exhaust and/or inflation.After said structure has assembled, also will vacuumize and be filled with nitrogen to seal casinghousing, the internal component of the flowmeter that is, in an oxygen-free environment, and then has effectively been avoided the corrosion of humid air to each components and parts.
As described in Figure 1, described conduit 10 is straight pipe, adopts straight pipe can reduce to greatest extent the pressure loss that fluid produces when by flowmeter.
Described seal casinghousing is enclosed and is formed by cylindrical sidewall 20 and upper and lower cover plate 21,22, the tube port position at described cylindrical sidewall 20 two ends is equipped with inside flange, described upper and lower cover plate 21,22 by rivet or bolt, be fixedly connected with flange and upper and lower cover plate 21,22 and flange between be equipped with O-ring seal 40.Seal casinghousing divides three parts independent moulding, and then assembles, and is more convenient for like this producing, and in technique, also than being easier to, realizes.
Described conduit 10 runs through cylindrical sidewall 20 and arranges, and described conduit 10 is integral type structure with cylindrical sidewall 20.Cylindrical sidewall 20 and conduit 10 can adopt plastics once injection moulding, also can adopt metal material first to process separately cylindrical sidewall 20 and conduit 10, then in cylindrical sidewall 20, offer through hole, again conduit 10 is passed to through hole, finally in conduit 10 and cylindrical sidewall 20 junctions, weld the two is connected as a single entity.
Described flow indication module 13 is oppositely arranged with upper cover plate 21, and described upper cover plate 21 is for transparent panel or at least comprise one for observing the transparent region of flow indication module 13, is convenient to testing staff from the reading of visual observation flowmeter.Valve 221 is arranged on lower cover 22, is convenient to like this valve 221 and is connected with source of the gas.
