than one meter. In recent years, water meter is arranged on the indoor and caused many problems cause the attention of people increasingly: Home meter reading disturbs people 39。 s normal life and may lead to residential burglary, privacy and safety not guaranteed: management of meter reading me ter reading is not easy and large labor intensity: individual user steals water management departments to prevent and punish and so on. Because of these problems, water production has bee an inevitable choice. Therefore, the newly revised national standard ( code for design of building water supply GBJ1588article : residential building should be installed in household water meter, household water meter or household water meter digital display should be located outdoors. Meter households generally have the following ways: Household water meter concentrated in the roof ( water supply ) or the underlying space ( water supply ). This mode is often used for multistormy residential. In general a unit provided with a ladder of water meter water meter well ( box ), household water pipe along the interior tube or building wall into the indoor. The utility model has the 外文翻译 5 advantages of convenient reading。 reading, low labor intensity of workers, can avoid users water behavior. Disadvantages are: material consumption, head loss of pipeline, occupying larger space pipeline well, such as a wall is easy to affect the appearance of the building, the user branches not easy maintenance. Meter is arranged on the stair landing platform. Vertical water supply pipe is arranged on the platform, each provided with a water tank。 the water meter box embedded platform resting on both sides of the wall. The utility model has the advantages of: user branches short, saving material, low head loss of pipeline, the shorting is: water dispersed settings, meter reading personnel of great labor intensity。 usually indoor fire hydrant box is installed on a platform, so that the already crowded rest platform more cramped, traffic inconvenience to the layer is Meter centralized meter room, household water meter on the wall. The utility model has the advantages of the same with B, the disadvantages are: household pipeline must follow the public walkway under floor into interior and corridors, ceiling requirements. Will be the traditional ordinary mechanical water meter changes for telemetering water meter or IC card intelligent water meter. Remote water meter accurate calculation without reading, this form must be a deposit a certain amount of water, will recharge after insertion of the IC card water meter reading can be water. Because the remote water meter and IC card table relatively expensive and technically still exist certain problems, hence in practice has not been widely applied. Above a few kinds of watermeter, each has its advantages and disadvantages, concrete in practical engineering design in which way, by the design staff according to residential properties, grades and local industry management department supply pipe arrangement and laying. At present, to build the house in one hutch two defend very general already, even with some houses one hutch three defend one hutch four defend, kitchen, toilet, the balcony, and each water using point locations are more dispersed. User branches to water points along the interior floor pipeline such as hanging, inevitable requirement set indoor ceiling, wall should also have the anticondensation measures to bring inconvenience, household decoration, after all, not all tenants wanted to ceiling. ( the building water supply and drainage design specification ) GB15 2020(manuscript ) as 外文翻译 6 specified in article , water supp。
