Abstract
The utility model relates to the technical field of water meter metering and especially relates to a high-sensitivity error-adjustable water meter. The high-sensitivity error-adjustable water meter comprises a water meter shell, wherein a character wheel box is mounted in the water meter shell; an impeller box is mounted under the character wheel box; an impeller is mounted in the impeller box; a plurality of water outlets and a water inlet are respectively arranged at upper and lower ends of the impeller box; a baffle is arranged on a side wall of the water inlet; the upper part of the baffle is connected with a screw rod; the middle part of the screw rod is matched with a thread bush fixed on the impeller box; a knob is arranged at the top end of the screw rod; the screw rod and the knob extend out of the water meter shell. The high-sensitivity error-adjustable water meter has a simple structure. The baffle capable of being adjusted is arranged at the water inlet of the impeller box, so that the flow of water entering into the impeller box can be controlled, the water meter can be fine tuned and the error of the water meter is reduced.
Description
Technical field
The utility model relates to water meter measurement technical field, relates in particular to the adjustable water meter of a kind of highly sensitive error.
Background technology
At present, urbanite water consumption table majority is that water promotes the semi-invariant that vane rotary measures urbanite water consumption, i.e. rotor water gauge.Water meter can be divided into positive displacement and rotary wind type, and positive displacement is that equivalent is measured, and rotary wind type is to realize indirect measurement according to the rotating speed of the speed of current and impeller.Rotor water gauge can be divided into dry type and wet type, rotary-wing type wet water-meter is connected on water supply line, the gland on housing and its top forms volume, connecting portion between fluid intake and outlet is housing, and its top is counter, and bottom is impeller box, in impeller box, there are impeller and lower shaft, impeller box upper and lower end all has a lot of holes, below be blasthole, above be apopore.Impeller shaft in impeller box is connected with the armature spindle of counter, and water is entered in impeller box and promoted wheel rotation by blasthole, makes its driven gear rotate the semi-invariant that can show water.And if water enters after impeller box by inlet opening that current are very little can not impeller rotate, so the large wheel rotation that could promote of flow, initial-flow is large; And so can cause Running-water Company's little unsettled situations of error that exist of numeral many and that user's water meter shows that supply water, there is inequitable phenomenon to water supply company in the large low discharge error robustness that affects of initial-flow.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of highly sensitive error adjustable water meter, the error of adjustable water meter.
The utility model for achieving the above object, by the following technical solutions: the adjustable water meter of a kind of highly sensitive error, comprise water meter case, in described water meter case, character wheel box is installed, described character wheel and below are provided with impeller box, in described impeller box, impeller is installed, on described impeller box, multiple apopores and inlet opening that lower end is offered respectively, side, described inlet opening is provided with baffle plate, described baffle plate top is connected with screw rod, described screw rod middle part coordinates with the thread bush being fixed on impeller box, the top of described screw rod is provided with knob, described screw rod and knob extend to outside water meter case.
The beneficial effects of the utility model are: the utility model is simple in structure, and the baffle plate that can regulate in the water inlet setting of impeller box can be controlled current and enter into the flow of impeller box, thereby can finely tune water meter, has dwindled the error of water meter.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of impeller box in the utility model;
Fig. 3 is mounting structure schematic diagram of the present utility model;
In figure: 1, water meter case; 2, character wheel box; 3, impeller box; 4, impeller; 5, apopore; 6, inlet opening; 7, baffle plate; 8, screw rod; 9, thread bush; 10, knob.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, the adjustable water meter of a kind of highly sensitive error, comprise water meter case 1, character wheel box 2 is installed in described water meter case, described character wheel and below are provided with impeller box 3, impeller 4 is installed in described impeller box, multiple apopores 5 that described impeller box upper and lower end is offered respectively and inlet opening 6, side, described inlet opening is provided with baffle plate 7, described baffle plate top is connected with screw rod 8, described screw rod middle part coordinates with the thread bush 9 being fixed on impeller box, and the top of described screw rod is provided with knob 10, and described screw rod and knob extend to outside water meter case.Can drive bolt rotary by rotation knob, screw rod drives baffle plate to rise or declines, thereby can control accurately the flow velocity of current in water inlet, the utility model is simple in structure, the baffle plate that can regulate in the water inlet setting of impeller box, can control the flow that current enter into impeller box, thereby can finely tune water meter, dwindle the error of water meter.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
