Abstract
The utility model provides a double-rotor flow meter which is long in service life, high in accuracy and strong in reliability. The double-rotor flow meter comprises a measuring shell, rotors, a counter, and is characterized by further comprising a positioning gear, a sensor, a message sender and a waterproof sunscreen layer, the rotors are spiral rotors, the positioning gear is arranged between the two spiral rotors, the spiral rotors and the positioning gear are fixedly arranged inside the measuring shell, and the external portion of the measuring shell is connected with the sensor and the message sender. According to the double-rotor flow meter, due to the fact that the two spiral rotors are arranged inside the measuring shell and are separated through the positioning gear, the two rotors are not contacted with each other when the two rotors rotate, and accuracy of measuring is ensured. Due to the fact that the waterproof sunscreen layer is sprayed on an original measuring shell, the purpose that the double-rotor flow meter is not affected by external water and sunshine is ensured, and the service life of the double-rotor flow meter is prolonged.
Description
Technical field
The utility model relates to metering field, relates in particular to a kind of flowmeter.
Background technology
Flowmeter is for the flow of measuring the fluid of flowing through in the selected time interval, but spinner-type flowmeter now only is provided with two rotors in the metering shell, but since two rotors distance too proximal pole its when metered flow, influence each other easily, cause error to produce, influence staff's gage work; And the utility model is flow measuring apparatus, uses extensively, often be applied to outdoor, when outdoor utility and since the product time be exposed to outdoor easily by sunlight be exposed to the sun, rain erosion, flowmeter is of short duration serviceable life.
Summary of the invention
According to above technical matters, the utility model provides a kind of long service life, the accuracy height, the duplex rotor meter of good reliability, comprise metering shell, rotor, counter, it is characterized in that also comprising the sun-proof layer of Positioning Gear, sensor, signalling generator and waterproof, described rotor is helical rotor, be provided with Positioning Gear between described two helical rotors, described helical rotor, Positioning Gear are fixed on this metering shell inside, described metering shell is externally connected to sensor and signalling generator, and described metering shell external spray has the sun-proof layer of waterproof.
The beneficial effects of the utility model are: the utility model is provided with a pair of helical rotor in metering shell inside and by Positioning Gear a pair of helical rotor is kept apart, make when rotating, to reach each other between two rotors and do not contact mutually, guaranteed the accuracy of measuring, helical rotor plays the effect of cutting apart, calculate, transporting and draining fluid to be measured for unique movable body in the metering shell.Rotor is once discharged 8 times of shade volumes with the interior every revolution of enclosure space that forms of metering shell.The utility model outside also is connected with sensor, counter and signalling generator, as long as by the sensor metering rotor rotating number of times of calculating, can calculate the flow accumulation amount by counter, revolution according to per second, can measure instantaneous delivery, signalling generator can pass to control center with information; The utility model can guarantee that at the sun-proof layer of original metering shell spraying waterproof the utility model is not subjected to the influence of extraneous water and sunlight, has prolonged serviceable life of the present utility model.
Description of drawings
Fig. 1 is the utility model cut-open view;
Fig. 2 is the utility model metering shell cut-open view.
As shown in Figure 1 and Figure 2, metering shell-1, helical rotor-2, counter-3, Positioning Gear-4, sensor-5, signalling generator-6, the sun-proof layer-7 of waterproof;
Embodiment
According to Fig. 1, shown in Figure 2, the utility model further specifies:
At first in metering shell 1, fix two helical rotors 2, fix Positioning Gear 42 of two helical rotors then, again sensor 5, signalling generator 6 sum counters 3 are fixed on the metering shell 1, at last the sun-proof layer 7 of waterproof is sprayed on metering shell 1 outside.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
