Description

A kind of water meter of quantification stability

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 lower shaft is provided with in impeller box, impeller axle in impeller box is connected with the armature spindle of counter, existing water meter has the following disadvantages: one is when discharge is less, counts 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 of water meter of quantification stability, comprise watchcase, the right-hand member of watchcase is water inlet, left end is water delivering orifice, top in watchcase is counter volume, the lower shaft that bottom is impeller box and is fixed on bottom impeller box, lower shaft is provided with impeller, on impeller box, lower end offers multiple apopore and inlet opening respectively, it is characterized in that described impeller box center of inside position is provided with baffle circle, be provided with fluid between baffle circle and impeller to be entered by inlet opening and flow out from apopore the gap had to pass through, institute's impeller upper end is provided with the impeller axle be connected with counter armature spindle, owing to there is gap between baffle circle and impeller, can enter gap when water enters after impeller box from inlet opening, change the flow direction of water, enhance the expulsive force of current, promote wheel rotation, and not picture does not set up baffle circle forward position impeller and bottom is directly flowed out from apopore, improve the Stability and veracity 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 discharge of the impurity in water 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.
