Abstract
Disclosed is a highly sensitive water meter, pertaining to the waterway measurement apparatus field;, an obstructing board with an orifice arranged is arranged at the half of the central part of a water inlet; a pressure-limited ball valve is arranged at the orifice; a thin and long jet pipe is in parallel arranged at the other half of the water inlet; a small check valve is arranged on an end head of the jet pipe; an obstructing bar is arranged at the bottom of the small valve. The paralleling thin and long jet pipe structure can effectively improve the sensitivity of the measurement of the water meter so that the water flow, no matter in small stream or in large quantity, can be measured inside the same water meter without water leakage so that the measurement can be fair and reasonable, and the stealing and leaking of the water as well as the wasting of the water can be prevented.
Description
(1) technical field
The utility model belongs to measuring apparatus field, water route, specially refers to a kind of high sensitivity water meter that is contained in the water route.
(2) background technology
China is as the country of a water resource sleepiness, water-saving notion is rooted in the hearts of the people at large, administrative authority is the waste that further reduces water, consumption with the lever of price regulating pondage, this just correspondingly requirement reasonably water metering standard should be arranged accurately, at present in market and the employed tap water meter of family, bigger metering leak often appears, when current are enough big, can correctly measure, and under the state of fine water droplet stream, because the impulsive force of water is not enough to drive the rotation of measurement wheel in the water meter, water meter is motionless state, flowing away silently and still have pencil without stop this moment, have the individual user opening the thin water of drip all the time, from morning to night uninterruptedly laying in water, this will form iniquitious friendship money state, in order to make water meter have no the just metering of leak, just wish that design is a kind of highly sensitive, do not let slip for unbroken fine water droplets yet, should be able to demonstrate its accumulation, so that charge is tending towards fair and rational.
(3) summary of the invention
The utility model technical issues that need to address are, in prior art, water meter could correctly measure when often having only big current, and water meter is motionless during weep, the weak point that sensitivity is not high, and redesign the high sensitivity water meter that a kind of fine droplets stream mode just can drive the water meter running.The purpose of this utility model is achieved through the following technical solutions, a kind of high sensitivity water meter comprises watermeter shell, the water meter lid, entery and delivery port, impeller and wheel chamber, pressure limiting ball valve, and the rotary flyweights on the dial plate, it is characterized in that, in half position, the middle part of water inlet, be provided with the baffler of a fenestrated, the place, aperture is equipped with a pressure limiting ball valve; Second half position of water inlet is provided with a thin straight tube side by side, and this jet pipe termination is provided with a unidirectional little valve, and this little valve bottom is provided with the obstruction grid.Described unidirectional little valve, its outer rim is greater than stopping the grid internal orifice dimension.Described obstruction grid, it is made by nontoxic rubber, and there is the fixedly little claw of usefulness at the edge, tightens with valve body.State when anhydrous circulation, unidirectional little valve is adjacent to the obstruction grid, make thin straight tube be in pent state, when the fine water droplet stream mode, the impulse force of water is not enough to go drive impeller so that be in the pressure limiting ball valve unlatching of closed state, under this state, unidirectional little valve is in opening because of water bundle pressure, thin straight tube ejection current drive impeller is rotated, and rotary flyweights rotates on the dial plate thereby drive, and is able to water is measured; When the water yield strengthened, hydraulic pressure overcomes pressure limiting ball valve gravity floated it, and current pour the channels drive impeller around this ball valve, and this moment, unidirectional little valve cut out at obstruction grid mouth, and water normally measures state in blade wheel chamber.The beneficial effects of the utility model are, the sensitivity that the side by side thin straight tube structure of this shunting action has improved water meter measurement effectively, making current no matter be in the fine water droplet stream mode still is big flow status, can both in same water meter, be measured watertightly, make metering fair and rational, and prevent the behavior of tax evasion water and reduced the waste of water.
(4) description of drawings
Fig. 1 is the synoptic diagram of water meter under user mode
Fig. 2 is this water meter inner structure synoptic diagram
Fig. 3 is that unidirectional little valve concerns synoptic diagram with the obstruction grid in this water meter structure
(5) embodiment
Further specify embodiment with reference to accompanying drawing, accompanying drawing 1 is synoptic diagram under the user mode in the water meter access water route, wherein watermeter shell 1 is serially connected in the pipeline, water inlet is 11, water delivering orifice is 12, this pipeline leads to the tap of water, on the dial plate of water meter top rotary flyweights 3 is arranged, the top is a water meter lid 2, with reference to Fig. 2, the inner structure relation of expression water meter, rotary flyweights 3 is connected with impeller 4 in the wheel chamber, below 5, by water inlet on one side, limited pressure ball valve 6 is seated in the place, aperture of baffler 7, is placing a thin straight tube 10 side by side with baffler, and a unidirectional little valve 8 is equipped with in its termination, because unidirectional little valve outer rim is greater than the internal orifice dimension that stops grid, so the action of this valve is subjected to stopping the restriction of grid 9.
Claims (3)
1, a kind of high sensitivity water meter comprises watermeter shell, water meter lid, entery and delivery port, impeller and wheel chamber, pressure limiting ball valve, and the rotary flyweights on the dial plate is characterized in that, in half position, the middle part of water inlet, be provided with the baffler of a fenestrated, the place, aperture is equipped with a pressure limiting ball valve; Second half position of water inlet is provided with a thin straight tube side by side, and this jet pipe termination is provided with a unidirectional little valve, and this little valve bottom is provided with the obstruction grid.
2, water meter according to claim 1 is characterized in that, described unidirectional little valve, and its outer rim is greater than stopping the grid internal orifice dimension.
3, water meter according to claim 1 is characterized in that, described obstruction grid, and it is made by nontoxic rubber, and there is the fixedly little claw of usefulness at the edge.
