Abstract
The utility model relates to a multifunction water meter chamber. A pipeline fixed in the multifunction water meter chamber adopts a compound structure with a straight through pipe and a bypass pipe, wherein, the straight through pipe is provided with a measuring water meter; a ball check valve is arranged in front of the water meter as the basis for calculating fire water quantity; in normal times valves on two sides of the water meter 3 are closed and a lead seal is opened to prevent users from stealing water; the ball check valve and the valves on two sides of the water meter 3 can form water stopping effect, which is convenient for replacing the water meter on the straight through pipe. The bypass pipe is provided with valves respectively fixed on two sides of the water meter, wherein, reducing pipes are respectively arranged between the valves and the water meter; according to practical water consumption of users, the water meter can be replaced at option so as to ensure that the water meter operates in the best measurement range. The utility model has the advantages that: the water meter chamber prevents users from stealing water, and is good in water saving effect as well as low in cost.
Description
Technical field
The utility model relates to a kind of communal facilities, particularly relates to a kind of multifunctional watermeter well.
Background technology
As everyone knows, at present, total water meter chamber pipeline is a forthright band bypass structure, but there is not metering water meter on the forthright, some user utilizes the forthright fire main to steal water, though bypass has the existing water meter table of metering water meter footpath not match with the actual used water amount, user's water supply volume has a long way to go sometimes, then water meter does not operate in optimal economic technical data scope, yet it is but very difficult with the water meter that the actual used water amount is complementary to want to be replaced with water meter table footpath, only way is to reconstruct well, thus waste of manpower, material resources and financial resources, and the waste of water is very big.
Summary of the invention
Main purpose of the present utility model is to overcome above deficiency and a kind of anti-stolen water is provided and arbitrarily changes water meter table footpath and the multifunctional watermeter well of the water meter that the actual used water amount is complementary.
The technical scheme that its technical problem that solves the utility model adopts is:, it comprises prefabricated box, well lid, water meter, pipeline and valve, it is characterized in that: be fixed on the duplex that the interior pipeline of multifunctional watermeter well prefabricated box adopts straight pipe and bypass pipe, straight pipe partly installs metering water meter additional, installs ball check valve before water meter additional; The bypass pipe part is fixed with valve respectively in the both sides of water meter, and a reducing pipe is respectively arranged between valve and the water meter.
Advantage and the good effect that the utlity model has are: increase metering and water-stealing-preventing but add water meter on the straight tube, other pipe is gone up in the both sides of water meter and is connected reducing pipe and fixed valve, can arbitrarily change water meter, makes water meter operate in best measures range, water-saving result is good, and cost is low.
Description of drawings
Fig. 1 is the structural representation of multifunctional watermeter well.
Among Fig. 1: 1. straight pipe, 2. bypass pipe, 3. water meter, 4. ball check valve, 5. water meter, 6. valve, 7. valve, 8. reducing pipe, 9. reducing pipe, 10. reducing tee,
The specific embodiment
For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1.
As shown in Figure 1: the pipeline in the multifunctional watermeter well is an example with the DN200/80 bore, adopt the duplex of straight pipe 1 and bypass pipe 2, straight pipe 1 place installs metering water meter 3 additional, it is effective to install non-return additional before water meter 3, the DN200 ball check valve 4 that depressurization is little, change and repacking for the ease of metering water meter 3 bores, straight-through fire protection pipeline bore is constant, the water meter 3 that installs additional, as calculating the fire-fighting water yield, valve-off 6 at ordinary times, 7 and play lead sealing and prevent that the user from stealing water, the flap valve 4 that installs additional before the water meter 3, so with the valve 6 of water meter 3 both sides, 7 can form the sealing effect, are convenient to the replacing of this water meter 3; Bypass pipe 2 bores are less than straight pipe, fixedly the reducing tee 10 of DN200 change DN100 is connected with DN100 elbow 11 and the two flange DN80 of undergauge, in the both sides of water meter 5 DN100 valve 12,13 is installed respectively, one reducing pipe 8,9 is respectively arranged between valve 12,13 and the water meter 5, effect by reducing pipe 8,9 can make the flow velocity of water accelerate, simultaneously, after installing like this, at any time increase to the water meter of DN100 with reference to the bore of water meter or narrow down to the water meter of DN80 according to user's actual used water amount, valve-off 12,13, change water meter 5, make water meter 5 operate in best measures range.The rest may be inferred, be that straight pipe 1 is during for DN200, be changed to DN100/DN80 or DN50/DN40 corresponding to bypass pipe 2, when straight pipe 1 is DN150, be changed to DN100/DN80 or DN50/DN40 corresponding to bypass pipe 2, the water meter that proves the different bores of ad eundem through the actual tests result is under the situation of same user, same water, and the effect of metering is different.The bore gap is more little, and error is also more little, and the bore gap is big more, and error is also big more, suitably in time both can reduce error in dipping if the water meter type selecting is changed; In addition, in case bypass pipe 2 parts break down when maybe needing to change water meter, but lashup straight pipe 1 and utilizes the metering water meter 3 of straight pipe 1 to measure.
Its advantage is: increase metering and water-stealing-preventing but add water meter on the straight tube, the upper both sides at water meter of other pipe connect Connect reducing pipe and fixed valve, can arbitrarily change water meter, make water meter operate in best measures range, joint Water is effective, and cost is low.
