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 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 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 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, 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 features such as the utility model has quantification stability, Anti-inversion.
