Abstract
The invention relates to the field of metering technologies for water meters, in particular to a high-sensitivity error-adjustable water meter which comprises a water meter shell. A character wheel box is mounted in the water meter shell, an impeller box is mounted below the character wheel box, an impeller is mounted in the impeller box, a plurality of water outlet holes and water inlet holes are respectively formed in the upper end and the lower end of the impeller box, a barrier is arranged on the side surfaces of the water inlet holes, the upper portion of the barrier is connected with a screw, the middle of the screw is matched with a threaded sleeve which is fixed onto the impeller box, a knob is arranged on the top of the screw, and the screw and the knob extend to the outside of the water meter shell all along. The high-sensitivity error-adjustable water meter has the advantages that the high-sensitivity error-adjustable water meter is simple in structure, the adjustable barrier is arranged at water inlets of the impeller box, the rate of water flow which flows into the impeller box can be controlled, accordingly, the water meter can be finely adjusted, and errors of the water meter can be lessened.
Description
Technical field
The present invention relates to water meter measurement technical field, particularly relate to the water meter that a kind of highly sensitive error is adjustable.
Background technology
At present, urbanite water consumption table majority is that water promotes vane rotary to measure the semi-invariant of 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 realizes indirect inspection according to the speed of current and the rotating speed of 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, impeller and lower shaft is had in impeller box, impeller box upper and lower end all has many holes, below be blasthole, above be apopore.Impeller axle in impeller box is connected with the armature spindle of counter, and water is entered in impeller box by blasthole and promotes wheel rotation, makes its driven gear rotate the semi-invariant that can show water.And if water enters by inlet opening that current after impeller box are very little can not impeller rotate, so the large wheel rotation that could promote of flow, namely initial-flow is large; And the large low discharge error robustness that affects of initial-flow, so Running-water Company's water supply can be caused many and the little situation that there is error instability of numeral of user's water meter display, inequitable phenomenon is existed to water supply company.
Summary of the invention
The object of the invention is to the deficiency overcoming above-mentioned technology, and the water meter providing a kind of highly sensitive error adjustable, the error of adjustable water meter.
The present invention for achieving the above object, by the following technical solutions: the water meter that a kind of highly sensitive error is adjustable, 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 apopore that lower end is offered respectively and inlet opening, side, described inlet opening is provided with baffle plate, described baffle plate top is connected with screw rod, coordinate with the thread bush be fixed on impeller box in the middle part of described screw rod, the top of described screw rod is provided with knob, described screw rod and knob extend to outside water meter case.
The invention has the beneficial effects as follows: structure of the present invention is simple, arranges the baffle plate that can regulate, can control the flow that current enter into impeller box, thus can finely tune water meter, reduce the error of water meter at the water inlet of impeller box.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the vertical view of impeller box in the present invention;
Fig. 3 is mounting structure schematic diagram of the present invention;
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
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, the water meter that a kind of highly sensitive error is adjustable, 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, coordinate with the thread bush 9 be fixed on impeller box in the middle part of described screw rod, the top of described screw rod is provided with knob 10, and described screw rod and knob extend to outside water meter case.Bolt rotary can be driven by rotating knob, screw rod drives baffle plate to rise or declines, thus can control accurately the flow velocity of current in water inlet, structure of the present invention is simple, at the water inlet of impeller box, the baffle plate that can regulate is set, the flow that current enter into impeller box can be controlled, thus can finely tune water meter, reduce the error of water meter.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
