（1）水力条件
(1) hydraulic conditions
只要给水管道内壁不结垢、润滑、润滑，才干削减水头丢失，确保效劳水头。橡胶软接头能下降振荡和噪声，并能补偿温度改变引起的热膨胀和缩短。广泛应用于各种管道体系中。
Only when the inner wall of the water supply pipeline is not fouled, smooth and smooth can the loss of water head be reduced and the service water head be guaranteed.The soft rubber joint can reduce vibration and noise, and compensate thermal expansion and contraction caused by temperature change.Widely used in various pipe systems.
（2）关闭功能高
(2) high sealing performance
供水管网是承压管网，管道只要杰出的合拢，是接连供水的根本确保。为了防止长期使用中橡胶软接头的天然萎缩和削减老化开裂，选用丝网进行多体保护。
Water supply pipe network is pressure pipe network, only good pipeline closure, is the basic guarantee of continuous water supply.In order to prevent the natural shrinkage of rubber soft joints in long-term use and reduce the aging of the fracture, the use of wire mesh for multi-body protection.
（3）建造出资省
(3) construction investment province
供水管网的建造本钱一般占供水体系工程造价的50％。因而，怎么经过技术经济剖析断定供水管网的建造规划，合理挑选管道资料和橡胶软接头，是管网合理运转的确保。
The construction cost of water supply pipe network usually accounts for 50% of the construction cost of water supply system.Therefore, how to determine the construction scale of water supply pipe network through technical and economic analysis, and how to rationally select pipe materials and rubber soft joints is the guarantee of reasonable operation of the pipe network.
（4）设备操控灵
(4) device control device
管网中的专用设备包含：阀门、消防栓、通风阀、排空阀、冲刷排水阀、减压阀、流量调节阀、水锤消除器、井筒保护、弹性设备、渣斗、流量和压力丈量设备等。这些设备的完整性是确保管网顺畅运转和防止污染的条件。橡胶软接头选用硫化成型，再与金属法兰或平行接头松套组合而成。
Special equipment in the pipe network includes: valves, fire hydrants, ventilation valves, exhaust valves, flushing and drainage valves, pressure reducing valves, flow regulating valves, water hammer eliminators, wellbore maintenance, telescopic devices, dregs, flow and pressure measuring devices, etc.The integrity of these devices is the premise to ensure the smooth operation of the pipe network and avoid pollution.The rubber soft joint is vulcanized and combined with metal flange or parallel joint loose sleeve.
（5）运送水质佳
(5) good water quality
经过长管道从自来水厂向用户自来水一般需求数小时乃至数天。管网实际上是一个大型反响堆。工厂水的未完成的化学反响将在管网中持续，而且氯水将与管壁新触摸，这或许发生新的反响。这些反响是生物学的。 ，感官和物理化学。橡胶软接头用于中空橡胶产品，其用作金属管之间的柔性接头。因而，要求管的内壁耐腐蚀而且不会将有害物质沉积到水中。
It can take hours or even days to deliver water from a water plant to customers through a long pipe.The pipe network is actually a large reactor.The unfinished chemical reaction of the factory water will continue in the pipe network, and the chlorine water will make new contact with the pipe wall, which may produce new reactions.These reactions are biological.Sensory and physical chemistry.The rubber joint is used for hollow rubber products and is used as a flexible joint between metal pipes.Therefore, the inner wall of the tube is required to be corrosion resistant and not to precipitate harmful substances into the water.
