Abstract
The utility model provides a high-precision water-saving water meter, comprising a watch case and a watch core. An additional device is arranged at the lower end of the watch core. The additional device comprises a tank body which can be communicated with the lower end of the watch core. An inlet is arranged at the bottom of the tank body. A one-way cock is arranged inside the inlet. An aperture is arranged on top of the tank body. In addition, an aperture is also provided below the impeller case inlet of the watch core. The aperture on the impeller case is corresponded to the aperture on top of the tank body. The utility model has the advantages of simple structure, low cost, water loss reduction for the feedwater branch and water use method regulation for people and can be widely applied to the intellectual water meter, the heat energy water meter, the remote indication water meter, etc.
Description
Technical field: the utility model relates to a kind of flowmeter, relates in particular to a kind of tap water meter.
Background technology: existing water meter comprises watchcase and watch core two parts.Watch core is installed in watchcase the inside, and the impeller of water impact watch core the inside begins metering, and this kind conventional water meter has following some deficiency, and the one, the requirement water velocity is big, when current can not accurate measurement during less than 30l/h; The 2nd, can install in the other direction, thereby make the impeller counter-rotating reach the stolen water purpose.
Summary of the invention: the purpose of this utility model is exactly at above-mentioned deficiency, and a kind of high precision water-saving type water meter is provided.This kind water meter just can accurate measurement during greater than 10l/h at flow velocity, and can avoid illegal user to reach the stolen water purpose by the upside-down mounting water meter.The utility model comprises watchcase and watch core, in the lower end of watch core an attachment device is installed.This attachment device comprises a staving that can be connected with the watch core lower end, the bottom of staving is provided with water inlet, the water inlet the inside is provided with one-way cock, aperture is left at the staving top, also be provided with aperture in addition below the impeller box water inlet seam of watch core, the aperture at aperture on the impeller box and staving top in correspondence with each other.Characteristics such as the utility model is simple in structure, and cost is low can reduce the water supply department damage by water, and standard people's water method can be widely used in intellectual water meter, heat energy water meter and remote transmitting water meter etc.

Embodiment:
Contrast Fig. 1 as can be known, the utility model comprises watchcase 1, watch core 2, lower end at watch core 2 is provided with attachment device, this attachment device comprises staving 8, the lower end of staving 8 is provided with water inlet 9, the bottom of water inlet 9 is provided with sieves 11, and water inlet 9 the insides are provided with one-way cock 6, and the top of staving is provided with staving top aperture 4.Be provided with impeller box aperture 5 below the water inlet seam of the impeller box 3 of watch core lower end, the inwall of water inlet is provided with guide rail 10, one-way cock 6 is provided with the guide groove (not marking among the figure) that matches with this guide rail 10 and to use, and makes one-way cock vertical moving and can not rotating up and down.The top of staving 8 is socketed on the outer rim of impeller box 3, and except that water inlet 9 and staving top aperture 4, all the other are in sealing state, forms a kind of fixedly flow field between staving and impeller box.Described one-way cock 6 can be unidirectional deadweight valve, relies on the weight sealing water inlet 9 of self; Also can be spring valve, spring 12 is installed above the top of valve, the bottom of the other end conflict impeller box 3 of spring 12.Under the effect of spring 12, one-way cock 6 sealing water inlets 9; One-way cock 6 also can be a Magnetic valves, promptly is provided with magnet 13 on the inwall of water inlet 9, is used to hold one-way cock 6, makes its sealing water inlet 9, and the bottom of impeller box 3 is provided with the spacing top 7 of float valve, is used to withstand the one-way cock 6 that floats.
The utility model principle of work is as follows: when water velocity was big, current one-way cock 6 jack-up, and entered staving 8 the insides from water inlet 9, thereby impacted the impeller metering; When water velocity hour, one-way cock 6 is closed water inlet 9, and current can only enter impeller box from staving top aperture 4 and impeller box aperture 5 corresponding positions, form one tiny current, and directly impact impeller, makes impeller rotation metering.Owing to form a kind of fixing flow field between staving and the impeller box, make the water movement state that enters impeller box in the staving constant relatively, thereby make the impeller rotational speed even, increased the accuracy of water meter measurement, in addition owing to all be provided with aperture on staving and the impeller box, when water velocity was little, current also can flow to and directly impact impeller and make water meter measurement from aperture, reached the purpose that improves water meter sensitivity.
