Abstract
The utility model provides a duplex water-saving water meter which comprises a main meter measuring larger flow and an auxiliary meter measuring smaller flow, wherein, a water inlet end and a water outlet end are respectively arranged at the two ends of the main meter, a water inlet channel and a water outlet channel communicated with the auxiliary meter are also arranged at the water inlet end and the water outlet end, the water inlet channel and the water outlet channel are respectively communicated with the water inlet end and the water outlet end, and a one-way valve is also arranged inside the channel between the water inlet end and the water outlet end. The utility model has the characteristics of simple structure, small size, short length, and low production cost, etc. The utility model especially facilitates the replacement of the prior ordinary meter.
Description
Technical field:
The utility model relates to a kind of compound water-saving type water meter, and the utility model is used to enlarge the measures range of water meter.
Background technology:
Water meter has one to overcome the initial flow of moving component stiction rotation and require water meter to provide the minimum flow of indicating value in limits of error limit, the water meter bore is big more, its initiating flow is just big more with the minimum flow that provides indicating value, does not promptly measure under the duty of low discharge.Helical vane type water meter the most frequently used in the large-diameter water meter is by a kind of water meter of forming around the screw wing rotor of flow axes rotation, and its advantage is that negotiability is big, the pressure loss is little, broad quantum, but bigger initiating flow is also arranged; For this reason, need a kind of compound water metre, it is made up of big flow water meter, low discharge water meter and flow conversion valve; When duty was low discharge, flow conversion valve was closed, by little water meter measurement; When flow increases to the conversion flow, participate in metering by big water meter; When flow was reduced to the conversion flow, cross-over valve cut out automatically, still by little water meter measurement; So both brought into play the advantage of large-diameter water meter, measured the low discharge duty again, and made the water meter measurement expanded range arrive the maximum flow of large-diameter water meter to the minimum flow of small diameter watermeter.
Above-mentioned compound water metre comparatively is typically " compound water metre " shown in a kind of China Patent No. 94102339.7 at present, and the outlet of the subtabulation of the measurement low discharge that its structure is settled in arm or by-path by the cross-over valve of the master meter of the big flow of a measurement, an automatism of settling thereafter, and arm or by-path is formed; Outlet feeds the conversion valve housing from side, and simultaneously, this cross-over valve comprises a complete switch module, wherein has a supporting mass, a central guide pins, blocking mechanism, a sealing surface and a ring cavity that holds blocking mechanism; This blocking mechanism has the edge of a dish type, and its first section is positioned at the cylindrical shape district of ring cavity in valve off-position amount.The compound water metre of above-mentioned China Patent No. 94102339.7 is owing to the water meter employing is horizontal spiral type structure, its water (flow) direction is laterally water inlet, described matching used with it be that cross-over valve is a spring structure, and be in same horizontal line with horizontal spiral type rotor, this structure can make that this product length in manufacture process is long, with the DN80 water meter is example, generally reach 370 millimeters, under the situation that does not influence performance, be difficult to make the length of 225 millimeters of traditional horizontal rotor water gauges, the replacing of inconvenient original water meter.And there is such problem too in the compound water metre that China Patent No. 03229226.0 provides.
The utility model content:
The purpose of this utility model just provides a kind of compound water-saving type water meter.
The purpose of this utility model can realize by following scheme.
Comprise the master meter of measuring big flow and measurement subtabulation than low discharge, the two ends of master meter are respectively equipped with water inlet end and water side, also be provided with the intake tunnel and the exhalant canal that are connected with subtabulation on water inlet end and water side, described intake tunnel and exhalant canal are communicated with water inlet end and water side respectively.
Described master meter comprises watchcase, watch core, impeller on the watch core is the rotary wind type impeller, be in the passage between water inlet end and the water side, its outside also is provided with a semi-enclosed impeller box, be convenient to impeller directed rotation under the impact of current, impeller is connected with water meter counter by transmission shaft, drives counter rotation metering, and the passage the inside between water inlet end and water side also is provided with an one-way cock.
Described one-way cock is a switch module, and described switch module comprises that one can set the flexible member of pretightning force.
Described one-way cock is from gravity valve or spring valve or Magnetic valves, or the arbitrary combination among their threes.
Described subtabulation is that existing various types of low discharge water meter, especially China Patent No. are 200320108689.7 high precision water-saving type water meter.
The utlity model has simple in structure, volume is little, length is short, characteristics such as cheap, the replacing of especially convenient existing common water meter.

Fig. 3, another master meter sectional view of the utility model
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
Contrast Fig. 1, Fig. 2 as can be known, the utility model comprises master meter 1 and subtabulation 2, the two ends of master meter 1 are respectively equipped with water inlet end 3 and water side 4, on water inlet end 3 and water side 4, also be provided with the intake tunnel 5 and the exhalant canal 6 that are connected with subtabulation 2, described intake tunnel 5 and exhalant canal 6 are communicated with water inlet end 3 and water side 4 respectively, described master meter comprises watchcase 7, watch core 8, impeller 9 on the watch core 8 is the rotary wind type impeller, be in the path 10 between water inlet end and the water side, its outside also is provided with a semi-enclosed impeller box 11, be convenient to impeller 9 directed rotation under the impact of current, impeller 9 is connected with water meter counter 12 by transmission shaft, drive counter rotation metering, the passage the inside between water inlet end and water side also is provided with an one-way cock.
Described one-way cock is a switch module 13, and described switch module 13 comprises that one can set the flexible member 14 of pretightning force.
Contrast Fig. 3 as can be known, described one-way cock also can be from gravity valve 15 or spring valve or Magnetic valves, or the arbitrary combination among their threes.
The utility model principle of work is as follows: when flow was opened needed hydraulic pressure less than one-way cock, current entered subtabulation from intake tunnel, and flowed out from exhalant canal, and at this moment, subtabulation is in running order; When the pressure of current reaches can back down one-way cock and open needed hydraulic pressure the time, at this moment, master meter and subtabulation are simultaneously in running order.
