Abstract
The utility model provides a high -sensitivity water meter, including watchcase, rotary wind type metering mechanism and indicating mechanism, water strainer and case, be provided with the impeller in metering mechanism's the casing, the lower part of casing is equipped with the inlet opening, and metering mechanism's casing is covered with the water strainer outward, and characterized by is equipped with a little through -hole on metering mechanism's casing lateral wall to, evenly distributed has four group's rill metering orifices on the relevant position in water strainer side week, is equipped with an annular ladder groove in the inboard of water strainer, it is recessed netted hole to have bottom the water strainer, the case sets up in this netted hole top, the delivery port the inside is equipped with the prevention inversion device, the prevention inversion device includes one way check valve and blocks the piece, one way check valve splices on the inner wall on delivery port upper portion, block the piece install on the inner wall of delivery port lower part, block that the piece is in one way check valve's bottom right side. The utility model has the characteristics of the measurement is accurate, prevention inversion etc.
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, and existing water meter has the following disadvantages: one is that water flow impact pressure is too small when discharge is less, can not promote impeller, water meter just cannot count; 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 accurate measurement 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 high sensitivity water meter, comprise watchcase, rotary wind type metering mechanism and indicating mechanism, water strainer and spool, wherein the two ends of watchcase are respectively equipped with water inlet and water delivering orifice, described metering mechanism is between water inlet and the water-flowing path of water delivering orifice, described indicating mechanism is connected with metering mechanism transmission, impeller is provided with in the housing of metering mechanism, the bottom of housing is provided with inlet opening, the housing shells of metering mechanism has water strainer, its upper edge is connected with the outward flange of this housing central section, it is characterized in that being provided with a small through hole in the housing sidewall of metering mechanism, and, the relevant position in water strainer side week is evenly distributed with four groups of rill metering-orifices, often group is three, a ring ladder groove is provided with in the inner side of water strainer, this ring ladder groove communicates with described four groups of rill metering-orifices, this ring ladder groove is made to become the circular passage being communicated with small through hole on described rill metering-orifice and described metering mechanism housing, thus the small circulation path that formation one is relatively independent, have bottom described water strainer in recessed reticulated cell, described spool is arranged on above this reticulated cell, under spool closed condition, spool closes this reticulated cell, when spool is opened, spool is spacing by the bottom of metering mechanism's housing of the side of being located thereon, at this moment, described reticulated cell is communicated with the inlet opening on metering mechanism housing, thus the books circulation path that formation one is relatively independent, described reticulated cell centre offers a ring, the valve seat inserting be connected with spool is in this ring, when current are larger, current are walk from books circulation path substantially, namely the reticulated cell after filtration bottom the network of rivers backs down spool automatically, the inlet opening flowing through metering mechanism's housing enters metering mechanism, normal metering, when current are small quantity, spool is because of pressure differential and the gravity of himself, the reticulated cell bottom water strainer can be closed, current are walked from small circulation path, namely the rill metering-orifice after filtration on the network of rivers enters circular passage, then flow through the small through hole on metering mechanism's housing and enter impeller place chamber, thus realize the function that water meter also can correctly measure when current are small, 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.
