Abstract

The utility model discloses a double finned water drop measuring meter, which comprises a shell body, a filtering net mask, a cylinder rack, a big rotating fin, a cup cylinder, and a counting unit, wherein the cylinder is equipped inside the net mask, the cup cylinder and the big rotating fin are equipped on the central axis of the cylinder rack, a circular gear on top of the big rotating fin rotating shaft is connected the counting unit, meanwhile the measuring meter is equipped with movable separating plates with a side water hole and a little rotating fin between the cylinder rack and the cup cylinder, when the water flow is big, the big rotating fin drives the work of the counting unit, when the water flow is normal or intermittent, the little rotating fin drives the work of the counting unit, thereby the utility model can measure accurately for no matter big water flow or intermittent water flow, suitable for one household one meter used measuring meter.

Description

The double-vane dripping water meter

One, technical field

The utility model relates to a kind of metering water meter, and the water meter that also can accurately measure during particularly a kind of dripping belongs to the metering water meter technical field.

Two, background technology

Existing most of metering water meter, only when current reached a certain amount of, the rotor in the ability red switch water meter rotated thereby drive to water meter counting pointer, realization water consumption counting, when current very little, even just during the dripping of discontinuity, because of its momentum corresponding very weak, to rotor can not be rotated thereupon, indicator of water gauge also just can not be counted certainly accordingly, like this, also will bring corresponding loss to relevant department.

Three, summary of the invention

The purpose of this utility model provides a kind of sensitivity, accurate metering water meter, even when very little current or discontinuous drip, can both accurately measure, for achieving the above object, the utility model adopts following technical scheme: the utility model comprises housing, filtering screen, the cylindrical shell seat, big rotor, the cup tube, counter assembly, on the cylindrical shell seat, be respectively equipped with main apopore and inlet opening on the barrel of hypomere, and the inlet opening section placed in the filtering screen, the cup tube, big rotor places on the central shaft of a base, the cylinder tooth of big rotorshaft epimere is connected with counter assembly, between tube base and cup tube, also be provided with active clapboard, described active clapboard is provided with secondary limbers, the center of secondary limbers is provided with little rotor, the opposite side of plane and little rotor position symmetry on the active clapboard, be equiped with the guide pipe of bottom opening, the counter assembly relevant position is provided with guidepost, reach a cup tube hypomere between the paddle hole of tube base inner wall stage casing and be provided with the step of placing restrictions on the active clapboard domain of walker, active clapboard fluctuates between two steps, the dividing plate top also is equipped with and little rotor meshed gears on the big rotor central shaft.Gear on the little rotor is a cylindrical gear, also can be the discontinuous cylindrical gear, with gear on the big rotor be continous way or discontinuous engagement.

The utility model is compared with existing metering water meter, and because of having increased active clapboard and little rotor, metering is sensitive, accurate, can carry out the accurate measurement of large and small current simultaneously.

Five, embodiment

As shown in Figure 1, dripping water meter described in the utility model comprises housing 1, filtering screen 2, tube base 3, big rotor 4, cup tube 5, counter assembly 10, on the tube base 3, be respectively equipped with main apopore and inlet opening on the barrel of hypomere, and its inlet opening section placed in the filtering screen 2, the big rotor 4 that has rotating shaft places on the central shaft of a base 3, cup tube 5 places on the base 3, counter assembly 10 places on the cup tube 5, between tube base 3 inwall stage casing paddle holes, reach cup tube 5 hypomeres limited step is set, be provided with active clapboard 7 between tube base 3 and the cup tube 5, described active clapboard 7 one sides have into the secondary limbers 6 that circumferencial direction is arranged, be provided with a fixed pivot at the center of described secondary limbers 6, lay little rotor 8 on this fixed pivot, little rotor 8 blades twist, the central shaft of little rotor stretches in the baseplane of counter assembly 10, the another side of plane and little rotor 8 position symmetries on the active clapboard 7, be provided with bottom guide pipe 11 radially with holes, counter assembly 10 relevant positions are provided with guidepost 12, active clapboard 7 is placed big rotor central shaft, plane on active clapboard, big rotor central shaft epimere also is provided with to be installed and little rotor meshed gears 9, be the up and down scope of restriction active clapboard, between tube base 3 paddle holes, reach a cup tube lower inside and be provided with limited step, active clapboard 7 is floated along big rotor central shaft between

tube base

3 and 5 liang of steps of cup tube, and counter assembly 10 is connected cup tube 5 upper ends.

When using this double-vane dripping water meter, when water swivel is closed fully, active clapboard sinks down into the lower position together with little rotor, whole metering water meter was in and treated duty this moment, inner pressure everywhere equates, pressure equilibrium, when fetching boiling water tap, because plane space pressure reduces on the active clapboard, form pressure differential, active clapboard moves up under the effect of pressure of supply water, set water inlet directly is communicated with water delivering orifice on the tube base, current continuously outflow, the big rotor of red switch, thereby drive counter assembly work counting, when water swivel does not close the water supply of formation low discharge fully, in the metering water meter everywhere pressure approach balance, active clapboard sinks down into the lower position under himself action of gravity, the intake-outlet on the tube base is cut off, and current are in a small amount concentrated and passed through from the secondary limbers of active clapboard, main apopore from the tube base flows out again to the top of active clapboard, the cross flow that variation is loose is the current of concentrating relatively, thereby forms stronger impulsive force, and the little rotor of red switch rotates, and, realize low discharge by driving counter assembly work counting with little rotor meshed gears, the purpose that discontinuous drips and measures.
