The utility model is characterized in that a large capacity metering water channel and a small capacity metering water channel, wherein the water inlet ends of the large capacity metering water channel and the small capacity metering water channel are communicated with the water inlet of the meter casing, and the water outlet ends of the large capacity metering water channel and the small capacity metering water channel are communicated with the water outlet of the meter casing; the existing transmission metering assembly is arranged in the large capacity metering water channel, and the water outlet end of the existing transmission metering assembly is provided with an automatic water baffling valve; an impeller chamber is also arranged in the small capacity metering water channel, and a small metering impeller is arranged in the impeller chamber; a rotating shaft of the small metering impeller is provided with a small metering gear engaged with a counting gear of the existing transmission metering assembly. The utility model realizes the purpose of water theft prevention by using simple structure, and has the advantages of accurate metering and convenient maintenance.
Description
Technical field
The utility model relates to a kind of tap water meter, particularly anti-stolen water tap water meter.
Background technology
At present, the tap water meter that uses in the water supply network is owing to the defective in the design, and it is when water velocity is very slow, and water meter turbine is difficult to rotate, and causes the water consumption metering inaccurate.Therefore now a lot of users catch existing this defective of water meter, just water swivel are reached minimum position, and formation is dripped or linear flow water, but water meter do not change, and steal tap water, cause enormous economic loss to Running-water Company.If what unit users adopted is the metering method of submeter and summary table,, have influence on neighborhood relationship because user's this behavior also can cause sub-metering number and summary table stoichiometric number not right.
Summary of the invention
Even goal of the invention of the present utility model provides a kind of when discharge is very little, the anti-stolen water tap water meter that also can accurately measure is to solve the weak point that existing tap water meter exists.
In order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is: anti-stolen water tap water meter, the table that comprises the watchcase with entery and delivery port and cover on watchcase metering form covers and existing transmission metering assembly, it is characterized in that: in watchcase, be provided with a large capacity meter water gaging road and a small flowmeter water gaging road, wherein the water inlet end in large capacity meter water gaging road and small flowmeter water gaging road is communicated with the water inlet of watchcase, and the water side in large capacity meter water gaging road and small flowmeter water gaging road is communicated with the water delivering orifice of watchcase; Existing transmission metering assembly is installed in the large capacity meter water gaging road, and in its water side one automatic water stopping valve is housed; Also be provided with a blade wheel chamber in small flowmeter water gaging road, subtotal amount impeller is installed in this blade wheel chamber; The one little measurement gear that is meshed with counting gear in the existing transmission metering assembly is housed in the rotating shaft of subtotal amount impeller.
Owing to adopted technical scheme as above, when the user with water swivel open very little, formation is dripped or during line water, because the pressure reduction of entery and delivery port is very little on the watchcase, at this moment the automatic water stopping valve that is installed on the water side, large capacity meter water gaging road can not be opened, tap water is just with the water inlet of very slow flow velocity by watchcase, through the water inlet end in small flowmeter water gaging road by small flowmeter water gaging road, and through the water side in small flowmeter water gaging road the water delivering orifice from watchcase flows out.Tap water is when flowing through small flowmeter water gaging road, to promote subtotal amount wheel rotation, subtotal amount impeller by the existing transmission metering assembly work of subtotal amount gear driven, carries out the low discharge metering again, and user's utilization is dripped or the method for unwrapping wire water is stolen tap water to stop.If the user with water swivel open very big after, the pressure reduction of entery and delivery port becomes big on the watchcase, at this moment the automatic water stopping valve that is installed on the water side, large capacity meter water gaging road is opened, tap water is just with the water inlet of very fast flow velocity by watchcase, water inlet end through large capacity meter water gaging road passes through large capacity meter water gaging road, and flows out with the water delivering orifice of automatic water stopping valve from watchcase through the water side in large capacity meter water gaging road.Tap water is when flowing through large capacity meter water gaging road, and existing transmission metering assembly measures normally.The simple structure of the utility model utilization has just realized preventing the surreptitiously purpose of water, and has accurate measurement, advantage easy to maintenance.Owing in the water side in large capacity meter water gaging road automatic water stopping valve is housed, if with water meter upside-down mounting described in the utility model, water stopping valve can't normally be opened automatically, so the utility model can also prevent that user's upside-down mounting water meter from stealing tap water.

Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is the transmission synoptic diagram between the first order gear in little measurement gear described in the utility model and the existing transmission metering assembly;
Embodiment
As Fig. 1, Fig. 2 and anti-stolen water tap water meter shown in Figure 3, comprise watchcase 1 and cover table lid 2 and existing transmission metering assembly 3 on watchcase 1 metering form with entery and delivery port 11,12.In this embodiment, existing transmission metering assembly 3 is exactly the transmission measuring apparatus of existing water meter, is not described in detail at this.
In watchcase 1, be provided with a large capacity meter water gaging road 13 and a small flowmeter water gaging road 14, wherein the water inlet end 131,141 in large capacity meter water gaging road 13 and small flowmeter water gaging road 14 is communicated with the water inlet 11 of watchcase 1, and the water side 132,142 in large capacity meter water gaging road 13 and small flowmeter water gaging road 14 is communicated with the water delivering orifice 12 of watchcase 1; Existing transmission metering assembly 3 is installed in the large capacity meter water gaging road 13, and an automatic water stopping valve 4 is housed in the water side 131 in large capacity meter water gaging road 13; Also be provided with a blade wheel chamber 143 in small flowmeter water gaging road 14, subtotal amount impeller 5 is installed in this blade wheel chamber 143; The one little measurement gear 6 that is meshed with meter 3 gears 31 in the existing transmission metering assembly 3 is housed in the rotating shaft of subtotal amount impeller 5.
As shown in Figure 1, the automatic water stopping valve 4 that this embodiment adopted, comprise valve body 41, valve rod 42, valve 43, torsion spring 44, valve body 41 is a drum, the one end is threaded with the water side 132 in large capacity meter water gaging road 13, and valve rod 42 radially passes valve body 41, and is connected with valve body 41 by torsion spring 44, valve 43 for valve body 41 endoporus adapt discoid, it is placed in the valve body 41 and with valve rod 41 and is connected.
Certainly, water stopping valve 4 can also be other version automatically, as valve 42 being made two semi-circular shapes, is connected with valve rod 41 hinges, and transmits the moment of torsion that opens and closes by torsion spring 44.When water swivel open very big the time, the pressure reduction of entery and delivery port 11,12 becomes big on the watchcase 1, the pressure of water promotes valve 42 and opens, water swivel is opened when very little, the pressure reduction of entery and delivery port 11,12 diminishes on the watchcase 1, torsion spring 44 is just closed valve 42.
