Pressure Reducing Valve

The PRV dataset is a water model required feature class that is consumed with it's specific behaviors set as rules for long term planning of the water system. Their positions also delineate the pressure zones that exist within the City's water system. Locations are derived from as-built drawings and have their locations verified with a survey grade GPS unit. Attribute Information: Field Name Description InstallDate The date when the asset was installed. Typically pulled from the as-built cover sheet for consistency. Infor required field. AssetID A unique identifier for the asset class. Infor required field. LifecycleStatus The current status of the asset with respect to its location in the asset management lifecycle. Infor required field. LocationDescription Information related to the construction location or project name. Infor required field Notes Stores textual information denoting which pressure subzones the PRV delineates.PRV（Pressure Reducing Valve，减压阀）数据集是供水模型必需的特征类数据集，其特定行为被设定为城市供水系统长期规划的规则依据。该数据集的点位同时划定了城市供水系统内的压力分区。点位信息源自竣工图纸，并通过测量级GPS设备完成位置核验。 属性信息如下： 1. InstallDate（安装日期）：该资产的安装日期。为保证数据一致性，通常从竣工封面页提取，为Infor系统必填字段。 2. AssetID（资产唯一标识符）：该资产类别的唯一标识，为Infor系统必填字段。 3. LifecycleStatus（资产生命周期状态）：该资产在资产管理生命周期中所处的当前状态，为Infor系统必填字段。 4. LocationDescription（位置描述）：与施工地点或项目名称相关的信息，为Infor系统必填字段。 5. Notes（备注）：存储文本信息，用于说明该PRV所划定的压力子分区情况。
