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 by upside-down mounting, provides the chance of stolen water to lawless person.
Utility model content
The purpose of this utility model is exactly provide a kind of quantification stability for above-mentioned situation and have the water meter of 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, described impeller comprises impeller axle and multiple blade, 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, 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, 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.
