Description
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 can cause showing to accelerate when being water meter Long-Time Service, affects the stable of water meter measurement; 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 rotor water gauge, comprise watchcase and table cover, the right-hand member of watchcase is water inlet, left end is water delivering orifice, table cover is arranged on the top of watchcase, watchcase and table cover hinged, counting mechanism is provided with in watchcase, counting box, impeller box, impeller and screen pack, it is characterized in that counting mechanism is arranged on the side in counting box, opposite side in counting box is provided with controller, heating and dehumidification device, pilot lamp and battery, controller, heating and dehumidification device, pilot lamp is connected successively with battery, counting box is arranged on the top of impeller box, O-ring seal is provided with between counting box and impeller box, the side of impeller box bottom is provided with inlet opening, the impeller box top opposite side corresponding with inlet opening is provided with apopore, impeller is arranged in impeller box, screen pack is arranged between impeller box and watchcase, inlet opening place is parallel with water (flow) direction and the side of water impact vane edge is provided with baffle plate, described counting mechanism comprises counter, reduction gearing and runner, counter is arranged on above reduction gearing, runner engages with reduction gearing, due to parallel with water (flow) direction at inlet opening place and water impact vane edge side arranges baffle plate, make the off-centring of current, current are allowed to beat in the position in the middle of impeller, avoid water meter Long-Time Service and the phenomenon causing water meter to accelerate, thus ensure the stable of water meter measurement performance, heating and dehumidification device is set in water meter, enabling of heating and dehumidification device is controlled by controller, avoiding water meter causes the inside surface of table cover to occur mist layer through moisture, staff is caused to be not easy to reading, and easily damage the problem of water meter, 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 one-way cock and stopper, described one-way cock hinge joint is on the inwall on water delivering orifice top, described stopper is arranged on the inwall of water delivering orifice bottom, described stopper is on the right side of the bottom of one-way cock, one-way cock can only be overturn left, and can not overturn to the right, when the utility model positive dirction is installed, under the effect of hydraulic pressure, one-way cock overturns left, current flow out water delivering orifice, and when current reversed flow, one-way cock is blocked by stopper, bottling up current enters in watchcase, 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.
