T/CI 131-2022 Intelligent Pipe Network Overlay (Negative Pressure) Water Supply Equipment

Scope

Scope: This document specifies the terms and definitions, models, materials, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of intelligent pipe network supercharged (non-negative pressure) water supply equipment. This document is applicable to the production and inspection of non-negative pressure pipe network pressurization and flow stabilization water supply equipment (hereinafter referred to as "equipment") for living and production water supply systems. Main technical content: 6. Technical requirements 6.1 Appearance 6.1.1 The surface of the equipment shall be smooth and even, with no defects such as bumps, scratches, or local deformation. The areas sprayed with plastic or painted shall not have defects such as peeling, delamination, bubbling, or flow marks. 6.1.2 The composition of the equipment is shown in Appendix A. 6.1.3 The surface of stainless steel equipment shall be treated with mirror or matte pickling and passivation. 6.2 Performance requirements 6.2.1 The supercharged water supply function of the equipment shall be able to supercharge water supply above the specified pressure value of the water supply pipe network. 6.2.2 Flow and head: When the equipment is operating normally, its flow and head shall not be less than 95% of the rated value. 6.2.3 The non-negative pressure function of the equipment shall have the function of non-negative pressure, that is, the equipment shall not cause negative pressure impact on the municipal water supply network or pressurized pipe network during operation. 6.2.4 The full-sealed and flow-stabilizing compensation function: The equipment shall operate in a fully sealed environment. When the water output exceeds the water input for a short period of time, the water in the flow-stabilizing tank shall be able to be transported to the user's pipe network, playing a role in stabilizing the flow and instantaneously adjusting the flow compensation.
