Description

A kind ofly count stable water meter

Technical field

The utility model relates to a kind of water meter.

Background technology

Existing water meter comprises watchcase, the two ends of watchcase are respectively equipped with water inlet and water delivering orifice, counter and impeller box is provided with in watchcase, impeller and top is provided with in impeller box, existing water meter has the following disadvantages: one is easily produce eddy current in impeller box, affect the stability of wheel rotation, cause counting inaccurate; Two is easily generate incrustation scale, affects the quality of water; Three is easily by upside-down mounting, provides the chance of stolen water to lawless person.

Utility model content

The purpose of this utility model provides a kind of quantification stability for above-mentioned situation exactly, is not easy to generate incrustation scale and the water meter with Anti-inversion function.The purpose of this utility model realizes by following scheme: a kind ofly count stable water meter, comprise watchcase, the right-hand member of watchcase is water inlet, left end is water delivering orifice, top in watchcase is counter volume, bottom is impeller box, impeller and top is provided with inside impeller box, described impeller comprises rotation axis and multiple blade, described rotation axis comprise magnet end and with the top conflict end contacted, described impeller box bottom is provided with and regulates water hole, it is characterized in that described blade surface is provided with the curved drainage trough in cross section, because blade is provided with drainage trough, the blocking-up face run into when reducing current flowing, current flowing is more smooth and easy, and reduce the weight of impeller, make the initiating amount needed for wheel rotation less, sensitiveer to the water yield change of low discharge, screen pack is provided with bottom described impeller box, described screen pack comprises sidewall and bottom surface, described sidewall is conflicted with the inwall bottom impeller box and is connected, described bottom surface is provided with several filter bores and some inclined tab, described inclined tab uniform ring is located at one end of bottom surface, described inclined tab and end face are all in incline structure, described inclined tab vergence direction all tilts along end face circumferential direction homonymy, described filter bores is all inclined to set, the vergence direction of described filter bores is identical with the vergence direction of described inclined tab, the sidewall of described screen pack is provided with concave inward structure, the inwall of the impeller box that described screen pack is corresponding is provided with the groove matched with concave inward structure, described concave inward structure and groove surround formation placed cavity, some rollers are provided with in described placed cavity, because inclined tab and screen pack end face are incline structure, after screen pack circumference rule inclination inclined tab, the flow direction is changed when current run into, expulsive force is produced to blade, promote blade to move towards its vergence direction, and then make screen pack when there being current to pass through, rotate along its circumferencial direction, reduce the probability of foreign matters from being blocked filter bores, when foreign matters from being blocked filter bores, the screen pack rotated can provide certain centrifugal force, foreign matter is thrown away filter bores, ensure the even of discharge, avoiding water velocity to improve makes the rotating speed of impeller increase, cause the inaccurate of metering, filtrator is provided with in the water inlet of watchcase, described filtrator is provided with external thread, described water inlet is provided with internal thread, described filtrator is removably connected by screw thread and water inlet, described filtrator is provided with filtering layer, described filtering layer is the ceramic filtering bed of material be intervally arranged, Quadrafos filter material layer and organophosphorus filter material layer, described filtering layer put in order for, from the ceramic filtering bed of material that water inlet and water delivering orifice direction are intervally arranged successively, Quadrafos filter material layer and organophosphorus filter material layer, the filtering layer in filtrator is had to pass through when current enter water inlet, current are through filtrator, water first flows to organophosphorus filter material layer through ceramic filter material laminar flow to Quadrafos filter material layer again, this arrangement mode is to prevent the too fast consumption of Quadrafos, Quadrafos filtrate and ceramic filter material and organophosphorus filtrate are combinationally used, ceramic filter material is the granule filter material comprising oxide ceramic powder, the feature of ceramic filter material meets water release active oxygen, because active oxygen has extremely strong oxidability, can make Quadrafos filtrate, in stationary water, passivation occur, so that dissolution velocity obviously slows down.In addition, the active oxygen self of ceramic filter material release has sterilization algae removal, reduce the function of biochemical oxygen demand figureofmerit in water, effectively can suppress water quality pollution in other respects simultaneously, as micro-content organism pollutes, heavy metal pollution, chlorine pollution etc., active oxygen generates along with the hydrolytic process of ceramic filter material, organophosphorus antisludging agent is generally liquid, in order to realize technique effect of the present utility model, organophosphorus antisludging agent is needed to make solid particle, to make it have slow-release function, scale inhibition effect can be ensured, ensure the stability strengthening Quadrafos again, control the burst size of organophosphorus filtrate simultaneously, make it have sufficiently long serviceable life, and be Quadrafos filter material layer for what mainly play scale effect in water, its U.S. ion of calcium that can absorb in water prevents the generation of upper incrustation scale, here Quadrafos filtrate mainly refers to polyphosphate glass ball, for absorbing the U.S. ion of calcium in chilled water, Quadrafos can also form diaphragm in metal surface under certain condition, play corrosion inhibition, by this filtrator, greatly will improve watchcase inside and prevent incrustation scale generative capacity, improve the quality of potable water, Anti-inversion device is provided with inside described water delivering orifice, described Anti-inversion device comprises interior water delivering orifice, spheroid, upper block and lower block, described upper block to be welded on water delivering orifice on inwall, described lower block block welding is under water delivering orifice on inwall, and it is corresponding with interior water delivering orifice, described spheroid is arranged between block and lower block, when the utility model positive dirction is installed, under the effect of hydraulic pressure, spheroid is washed from upper block and is blocked by lower block, current flow out water delivering orifice by gap, and when current reversed flow, spheroid is rushed upstop and is pressed on interior water delivering orifice, anti-water-stop body flows backwards, the bottom of described watchcase is provided with sewage draining exit, described sewage draining exit is provided with buckle closure, described buckle closure is tightened on sewage draining exit by screw thread, because the bottom at watchcase is provided with sewage draining exit, only need open buckle closure can regularly clear up the impurity in water meter, avoid the impurity in water to discharge and do not go out the phenomenon causing water meter to block.The utility model has quantification stability, Anti-inversion, is not easy to generate the features such as incrustation scale.
